IELTS Reading Passage - Population Movements And GeneticsPopulation Movements And GeneticsOrigins and distribution of human populations is studied based on archaeological and fossil evidence. From the 1950s, numerous techniques have been used which are more objective. Information about early population movements now obtained by 'archaeology of the living body', the clues are taken from the genetic material.These values of the techniques are ensured by the work on the problems which deal with when people entered America. The launching ground of human colonisers of the New World is North-east Asia and Siberia. It was found that major migration happened across the Bering Strait into the Americans. New clues have derived from the research into genetics which includes the genetic markers in modern Native Americans.Biological Anthropologist Robert Williams found one particular protein (immunoglobulin G) in the form of fluid in the blood. Most of the proteins produce variants and interbreeding human population members will share these sets of variants. One can determine their genetic distance by comparing the Gm allotypes of two different populations. This informs the length of time.In the span of a twenty year period, Williams and his colleagues collected the sample of over 5,000 American Indians in Western North America. . Gm allotypes can be divided into two groups, one of them corresponds to the genetic typing of Central And South American Indians. Apart from this, other tests showed that Aleut3 and Inuit formed a third group. It was found from the evidence that there have been three migration waves that happened across the Bering Strait. da about 600 or 700 years ago). The third wave, perhaps 10,000 or 9,000 years ago, saw the migration from North-east Asia of groups ancestral to the modern Eskimo and Aleut.To what extent does other research support these conclusions ? Douglas Wallace, a geneticist, studied mitochondrial DNA4 in the blood samples from three distinct Native American Groups: Arizona’s Pima-Papago Indians, Maya Indians on the Yucatan Peninsula, Mexico, and Ticuna Indians in Brazil's Upper region. According to the prediction of Robert Williams’s work, all three groups seem to be descended from the same ancestor - thePaleo-indian population.There are two other sorts of research which throws some light on the Native American Population origination. It involves the study of teeth and of languages. The biological anthropologist Christy Turner, having an expertise in analysing the changing physical characteristics in human teeth. According to him, tooth crowns and roots possess a high genetic component, affected by environmental and other factors in a minimal fashion. Turner studied many thousands of New and Old World Specimens, both ancient and modern and finds that most of the prehistoric Americans are connected to Northern Asian Populations byroot and crown traits such as incisor shovelling ( a scooping out on one or both surfaces of the tooth ), triple-rooted lower first molars and single-rooted upper first premolars.As stated by Turner, this ties in with the idea of a single Paleo-Indian migration out of North Asia, which he fixes before 14,000 years ago by calibrating rates of dental micro-evaluation. Analysing the tooth suggests that there were two later migrations of Eskimo-Aleut andNa-Denes.Since the 1950s, the linguist Joseph Greenberg has argued that all Native American languages belong to a single ‘Amerind’ family, Na-Dene and Eskimo-Aleut is an exception -a view that supports the idea of three main migrations. Among fellow linguists, Greenberg is a minority, who favour the idea of many waves of migration to account for the fact that American Indians speak more than 1000 languages at one time. Greenberg’s view is supported by the new genetic and dental evidence. However, dates given for the migrations should be treated cautiously, excluded where supported by hard archaeological evidence.

专业英语四级-71(总分100,考试时间90分钟)READING COMPREHENSIONTEXT AIn a recent book entitledThe Psychic Life of Insects, Professor Bouvier says that we must be careful not to credit the little winged fellow with intelligence when they behave in what seems like an intelligent manner. They may be only reacting. I would like to confront the Professor with an instance of reasoning power on the part of an insect which cannot be explained away in any other manner.During the summer, while I was at work on my doctoral thesis, we kept a female wasp at our cottage. It was more like a child of our own than a wasp, except that it looked more like a wasp than a child of our own. That was one of the ways we told the difference.It was still a young wasp when we got it and for some time we could not get it to eat or drink, it was so shy. Since it was female, we decided to call it Miriam.One evening I had been working late in my laboratory fooling around with some gin and other chemicals, and in leaving the room I tripped over a line of diamonds which someone had left lying on the floor and knocked over my card index which contained the names and addresses of all the larvae worth knowing in North American. The cards went everywhere.I was too tired to stop to pick them that night. As I went, however, I noticed the wasp was flying about in circles over the scattered cards. "Maybe Miriam will pick them up", I said half laughingly to myself, never thinking for one moment that such would be the case.When I came down the next morning Miriam was still asleep in her box, evidently tired out. And well she might have been. For there on the floor lay the cards scattered all about just as I had left them the night before. The faithful little insect had buzzed about all night trying to come to some decision about picking them up and arranging them in the boxes for me, and then had figured out for herself that, as she knew practically nothing on larvae of any sort except wasp larvae, she would probably make more of a mess of rearranging them than if she had left them on the floor for me to fix. It was just too much for her to tackle, and discouraged, she went over and lay down in her box, where she cried herself to sleep.1. Professor Bouvier most probably agrees that ______.A. insects" reasoning power has nothing to do with intelligenceB. wasps can only behave in an instinctive mannerC. wasps are different from other winged creaturesD. the issue of insects" intelligence need further research2. The author took the wasp Miriam to his cottage because ______.A. Miriam was treated like a childB. Miriam was the pet of the familyC. the author was studying insects for his doctoral thesisD. the author wanted to prove that insects have intelligence3. When the card index scattered on the floor, the author ______.A. decided to pick them up the next morningB. believed Miriam would pick them upC. didn"t understand why Miriam flew about over the cardsD. found it ridiculous that Miriam would pick them up4. By saying "And well she might have been" (Para. 6), the author thinks that Miriam was ______.A. exhaustedB. intelligentC. energeticD. depressed5. Which of the following statements was based on facts rather than on the author"s pure thinking?A. Miriam cried herself to sleep.B. Miriam had buzzed about all night.C. Miriam could only tell wasp larvae.D. Miriam had left the cards on the floor.An "apple polisher" is one who gives gifts to win friendship or special treatment. It is not exactly a bribe, but is close to it.All sorts of people are apple polishers, including politicians and people in high offices—just about everybody. Oliver Cromwell, the great English leader, offered many gifts to win the support of George Fox and his party, but failed.There are other phrases meaning the same thing as "apple-polishing"—"soft-soaping" or "buttering-up". A gift is just one way to "soft-soap" somebody, or to "butter him up". Another that is just as effective is flattery, giving someone high praise-telling him how good he looks, or how well he speaks, or how talented and wise he is.Endless are the ways of flattery. Who does not love to hear it? Only an unusual man can resist the thrill of being told how wonderful he is. In truth, flattery is good medicine for most of us, who get so little of it.We need it to be more sure of ourselves. It cannot hurt unless we get carried away by it. But if we just lap it up for its food value and nourishment, as a cat laps up milk, then we can still remain true to ourselves.Sometimes, however, flattery will get you nothing from one who has had too much of it. A good example is the famous 12th century legend of King Canute of Denmark and England. The king got tired of listening to the endless sickening flattery of his courtiers. They overpraised him to the skies, as a man of limitless might.He decided to teach them a lesson. He took them to the seashore and sat down. Then he ordered the waves to **ing in. The tide was too busy to listen to him. The king was satisfied. This might show his followers how weak his power.6. Which of the following activities has nothing to do with "apple-polishing"?A. A boy tells his girlfriend how pretty she looks.B. An employee tells her boss how good he is at management.C. A knight is said to be of limitless power by his followers.D. A teacher praises her students for their talent and wisdom.7. What does the writer want to prove with Cromwell"s example?A. Everybody can be an apple-polisher.B. Cromwell was not a good apple-polisher.C. George Fox and his party were not apple-polishers.D. There are people who don"t like being apple-polished.8. Which of the following statements about flattery is true according to the writer?A. Too much flattery can carry us away.B. Flattery is too empty to do people any good.C. Flattery can get you nothing but excessive pride.D. Flattery is one of the ways to apple-polish people.9. King Canute of Denmark and England took his followers to the seashore because ______.A. he was sick of his normal lifeB. he disliked being overpraised any moreC. he wanted them to realize how wise he wasD. he wanted them to see how weak he was as a king10. The author thinks that flattery can do good to those who ______.A. are politicians or in high officesB. lack confidenceC. are really excellentD. think highly of themselvesTEXT BAs medical evidence mounts that we are indeed what we eat, consuming a healthier diet has become almost a national passion in the United States. The food-for-fitness phenomenon began in the late "70s when a U.S. **mittee on nutrition reached grim conclusion that six out of the ten leading causes of death—such as heart disease, cancer, and stroke—might be linked to diet. The government issued dietary guidelines advising Americans to eat a variety of foods, maintain proper weight, and limit intake of fat, salt, sugar, and alcohol.For most Americans, what to eat is a matter of personal choice, rather than one of supply. An excellent nationwide food distribution system assures that fresh produce is readily available in all parts of the country, regardless of the season. Taking advantage of this abundance, many people are forsaking traditional meat-and- potatoes and in favor of lighter meals of salads, fruits, and vegetables.The single most dramatic change in the American diet has been a reduction in consumption of animal fat, which is thought to increase the risk of heart disease and may contribute to the high U.S. incidence of breast and colon cancer. Margarine and vegetable oils have replaced butter and lard in many homes, and half of all milk now drunk in the United States is low-fat. Fish and poultry are increasingly popular sources of protein as consumption of red meat declines. The food industry has responded to concern about fat by producing leaner cuts of meat and cholesterol-free substitutes for eggs.One of the most significant trends in the American way of eating is the healthful change in restaurant food. "One of every two meals in the United States is eaten outside the home," says Donna Watson, president of the American Dietetic Association. "Restaurants are making special efforts to provide low-fat, low-salt, and low-calorie items." Salad bars, loaded with fresh greens and raw fruits and vegetables, are found everywhere, even along-side the burgers and French fries in fast-food restaurants.Most important, the focus on prudent diet has led to an unprecedented national quest for a healthier life style. Americans are smoking less, exercising more, and experimenting with new ways to conquer stress. Eating sensibly, they have discovered, is only one important route to good health.1. It is suggested in the dietary guidelines that ______.A. 60% leading causes of death might be linked to dietB. fat and alcohol should be taken as little as possibleC. eating diverse foods helps maintain proper weightD. sugar and salt should be taken in restricted amount2. Many Americans no longer maintain the meat-and-potatoes diet because ______.A. salads, fruits, and vegetables are more easily preparedB. there is a rich supply of diverse foodsC. such diet is not as healthy as salads, fruits and vegetablesD. diverse foods vary with seasons3. Which of the following can be a way to decrease the consumption of animal fat?A. Using less butter when cooking soup.B. Drinking more milk at breakfast.C. Eating more fish or poultry at dinner.D. Having two eggs at most daily.4. What is the author"s attitude towards restaurant food?A. Optimistic.B. Impersonal.C. Enthusiastic.D. Anxious.5. A nationwide pursuit of a sounder life style began when the American realized ______.A. the disadvantages of smokingB. the advantages of exercisingC. the advantages of prudent dietD. the disadvantages of stressWith increasing prosperity, Western European youth is having a fling that is creating distinctive consumer and cultural patterns.The result has been the increasing emergence in Europe of that phenomenon well known in America as the "youth market". This is a market in which enterprising businesses cater to the demands of teenagers and older youths in all their rock mania and pop-art forms.In Western Europe, the youth market may appropriately be said to be in its infancy. In some countries such as Britain, West Germany and France, it is more advanced than in others. Some manifestations of the market, chiefly sociological, have been recorded, but it is only just beginning to be the subject of organized consumer research and promotion.Characteristics of evolving European youth market indicate dissimilarities as well as similarities to the American youth market.The similarities:The market"s basis is essentially the same—more spending power and freedom to use it in the hands of teenagers and older youth. Young consumers also make up an increasingly high proportion of the population.As in the United States, youthful tastes in Europe extend over a similar range of products—records and record players, transistor radios, leather jackets and "way-out", extravagantly styled clothing, cosmetics and soft drinks. Generally it now is difficult to tell in which direction trans-Atlantic teenage influences are flowing.Also, a pattern of conformity dominates Europe youth as in this country, though in Britain the object is to wear clothes that "make the wearer stand out," but also make him "in," such as tight trousers and precisely tailored jackets.Worship and emulation of "idols" in the entertainment field, especially the "pop" singers and other performers is pervasive. There"s also the same exuberance and unpredictability in sudden fad switches. In Paris, buyers of stores catering to the youth market carefully watch what dress is being worn by a popular television teenage singer to be ready for a sudden demand for copies. In Stockholm other followers of teenage fads call the youth market "attractive but irrational."The most obvious differences between the youth market in Europe and that in the United States is in size. In terms of volume and variety sales, the market in Europe is only a shadow of its American counterpart, but it is a growing shadow.6. The "youth market" is created so as to cater for ______.A. distinctive young consumers and their cultureB. the enterprising businesses in Western EuropeC. the increasingly prosperous European economyD. the emergence of an American phenomenon7. What does the author think about the youth market in Britain, West Germany and France?A. It is more developed than that in Western Europe.B. It is still in its preliminary stage of development.C. More sociological phenomena of the market should be recorded.D. Consumer research and promotion should be based on the market.8. The European youth market and the American one are similar in ______.A. the youth"s spending powerB. the youth"s influences on the marketC. the proportion of the youth populationD. the kinds of products that interest the youth9. Which of the following statements is true about the youth in Britain?A. Their dressing is dominated by a pattern of conformity.B. Their clothing is distinct from the other Europe youth"s.C. Tight trousers and precisely tailored clothes are their favorites.D. They are influenced by the conformity derived from the U.S.A.10. The author mentions the Paris and the Stockholm examples to illustrate ______.A. the prosperity of the youth marketB. the craziness of the fashion followersC. the unpredictable change of fashionD. the popularity of the fashion idolsTEXT CLogistically, it worked out best for me to fly east from Boston Logan to London Heathrow to Tokyo Narita, a trip which involves 26 hours of flight time and another 12 of waiting in airports. The time difference from Eastern Standard Time to Japan Time is 13 hours forward. I arrived at Logan at 3am, the 16th of June, and left Narita at 8am on the 18th. I"m afraid I wasn"t really in the best mental shape once I finally landed; my memories of processing through customs are sketchy reconstructions based on small flashes of recollection.What I remember most about that arrival is my luggage. Terry Pratchett and Neil Stephenson have both written amusingly about unwary travellers carrying too much baggage. I have to say that it"s a lot less amusing when it"s happening to you. I had imagined that the process on arrival would be like arrival at an American airport: I would pull the luggage off the conveyor and put it on a trolley, trundle it 100 yards, and load it into some sort of car. Accordingly, I didn"t really consider space or weight: I had two huge bags, each loaded to the 701b flight luggage limit. I had a giant cardboard box containing a full **puter system and two cubic yards of packing peanuts. I had another big box containing my bicycle. I was moving, after all, and this seemed a fairly minimal set of things to take for a stay of at least a year.The gentleman who **pany sent to greet me at the airport was cheerful about my situation. A lot of people who he met, he told me, had similar situations. There was a shipping office conveniently located within the airport which could freight whichever items weren"t immediately necessary to the apartment which would become mine. It didn"t matter that the larger box had gone squishy and organic, and was slowly leaking peanuts; the **panies were extremely talented here. In fact, he was very nice about everything—but he never once offered to help carry anything.I shipped off my cardboard boxes, but I hadn"t planned for a situation in which it would matter how much luggage I had, so necessary items were scattered between the two bags. We left for **pany guest house where I"d be staying: the cheerful semi-**pany man leading, and me following with 701b in each hand. We rode the train toward Chiba, with each of my bags taking up a pair of seats, and the two of us standing between them. We left the train station and started walking to the house. It wasn"t too far, he told me: less than two kilometers. We had the advantage of good weather, too: the temperature wasn"t expected to break 30 degrees, and the humidity was only 70.**pany man had it easy: he wasn"t carrying anything. As for me, I"ll just say that when you go to experience a foreign land, attempting a 2km walk while carrying 1401b of stuff in the first humidity of summer while exhausted is not the recommended starting point.It"s kind of funny, but I didn"t immediately feel like I was anywhere new. Yes, the roads were narrow, the people were Asian, and the writing was funny, but I"d seen each of those elements before. It wasn"t until the first time I went to get something to eat that I had a really profound understanding that I was in Japan. **pany man told me that I could survive eating prepackaged meals from convenience stores, and showed one to me on the way to the guest house. The first food 1 ate in that country was a strawberry cream sandwich. That sandwich provided my "not in Kansas anymore" moment; it took on a weird significance as my first step in participating in the widespread oddness that is Japanese culture.I slept for 14 hours that night, and woke up at 7am the next morning to a small earthquake. I was now in the Land of the Rising Sun, and those two elements had just cooperated to greet me. It felt good.1. The author found that he had only vague memories about ______.A. how he dealt with his luggageB. how he landed in Narita JapanC. how he passed through the customsD. how he got over the time difference2. The author would most probably describe the experience of unwary travelers with too much luggage other than himself as ______.A. interestingB. ridiculousC. painfulD. pleasing3. When the gentleman greeted the author, ______.A. he took the author"s luggage to the shipping officeB. he told the author he had never expected so much luggageC. he showed the author to the shipping officeD. he refused to help the author with his luggage4. The author didn"t ship off the two bags because ______.A. items in them were of higher valueB. items in them weren"t available in JapanC. they **paratively lighterD. they were of more immediate use5. The author finally realized he was in a foreign country when he ______.A. processed through customsB. ate his first meal in JapanC. got to the guesthouse on foot instead of by taxiD. came to narrow roads and Japanese peopleThe HMS Ontario is one of the most famous shipwrecks and was discovered by two Rochester engineers Jim Kennard, 64, who has spent more than half his life pursuing The HMS Ontario, along with Dan Scoville, 35, a shipwreck diver. They discovered The HMS Ontario deep off the southern shore of Lake Ontario when side-scanning sonar system that Mr. Kennard, a retired Kodak engineer, designed and built himself, showed a picture of something deep in Lake Ontario. The location of the shipwreck had been unknown for 228 years.Experienced shipwreck divers Jim Kennard and Dan Scoville have discovered seven of Lake Ontario"s estimated 500 shipwrecks in the last six years alone. Jim Kennard also designed a microwave-sized remote submersible that they deployed to go down and take the shipwreck"s video. The shipwreck is quite deep in Lake Ontario, so the remote machine with video was very useful."Right away we saw the quarter gallery, the windows in the stem, the cannons," said Jim Kennard. "There was no mistaking. That"s when we started getting excited." The discovery of the ship wreck was confirmed by the HMS Ontario expert Canadian Arthur Britton Smith, who authored the definitive book on the HMS Ontario.The loss of the HMS Ontario, is one of the worst-ever disasters recorded on Lake Ontario. In her time the HMS Ontario was the most-feared ship on the Great Lakes. It was 1780 and the Yankeeswere threatening to storm across Lake Ontario and seize Montreal from the British. But the intimidating 226-ton Ontario--22 cannons, two 80-foot masts, a beamy hull with cargo space for 1000 barrels, was intimidating. On Oct. 31, 1780, she sailed into a storm with around 120 passengers on board and was never seen again. The British tried to keep the news of the ship wreck hush.The HMS Ontario appears to be in perfect shape and the HMS Ontario has aged remarkably well though zebra mussels cover much of the woodwork. Leaning on a 45-degree angle, her masts still jut straight up from her decks where several guns lie upside-down and a brass bell, brass cleats and the stem lantern are perfectly visible. The Seven windows across her stem still have glass. Shipwrecks in cold freshwater are well preserved, that is why great lakes shipwrecks are prized. At 500 feet deep, where the HMS Ontario lies, there is no light and no oxygen to speed up the decomposition, and little marine life to feed on the wood.There was no evidence of the roughly 113 Canadian men, women, children and American prisoners who went down with the ship—the passengers—mostly Canadian soldiers from the 34th regiment—were never found. Nobody knows for sure how many passengers perished on the Ontario; the British kept their prisoner counts secret.Out of worries over looting, Mr. Jim Kennard and Mr. Dan Scoville are not revealing the HMS Ontario"s location. The vessel sits in water up to 500 feet deep and cannot be reached by anyone other than experienced divers. It is not believed to have any shipwreck treasure on it as was reported other than a few shipwreck coins that belonged to the passengers.Kennard said he and his partner have gathered enough ship wreck video of the ship that it will not be necessary to return to the site. He added that they hope to make a documentary about the discovery with the video of the shipwreck.The Great Lakes host many shipwreck locations and there are an estimated 4,700 shipwrecks in total, of which 500 are in Lake Ontario. Freshwater shipwrecks are famous for their preservation of the vessels and make popular diving spots.6. The two discoverers of the HMS Ontario saw its video ______.A. with the help of a scanning sonar systemB. with the help of a remote submersibleC. on an Ontario TV channelD. on a DVD about history7. The HMS Ontario was most probably a ______.A. cruise linerB. fishing boatC. war shipD. cargo ship8. Great Lakes shipwrecks are highly valued because ______.A. they are well protected against decompositionB. they need to be explored with high technologyC. they are of great use to the research of historyD. they have much well-preserved treasure on board9. What is NOT true about the HMS Ontario?A. No trace of human being has been found in the shipwreck.B. The passengers were evacuated before the ship sank.C. The ship used to belong to the British Navy.D. There was not much treasure on the ship.10. What will Jim and Dan do with the HMS Ontario shipwreck?A. They will take it to the surface when they get more financial fund.B. They will make it a popular diving spot.C. They will reveal the location of the ship when the video is released.D. They will leave the shipwreck where it is.11. Which paragraph is NOT about the finding of Jim and Dan?A. Paragraph 3.B. Paragraph 4.C. Paragraph 5.D. Paragraph 6.TEXT DThe 35-year-old Beijing woman is watching an ad showing a giant television made by the **pany Haler. A stream of introduction for the television floats in and out of view, including one about receiving electronic mail over the tube. A suffer tides the waves between skyscrapers, his wash leaving an "@" in the water. The ad is "too direct", she tells an interviewer. "There is this guy talking, telling me all about the product, showing me some images. We get it—but we don"t like it."Since a Shanghai television station aired China"s first TV commercial in 1979, most have been the plain, straightforward, tell-the-name-of-the-product-and-what-it-does kind. Those started disappearing in the U.S. in the late 1960s in favor of more subtle pitches using irony and humor. Now a study says **mercials don"t have to talk down to consumers anymore either—at least the one-third of them living in China"s prosperous cities, and who most interest advertisers.Even the Western agencies that win awards elsewhere for hip, **mercials usually keep it simple in China. After all this country only began flirting with capitalism 20 years ago and is fairly new to advertising. And to consumer culture, too. China is still a developing nation where an income of just $2,000 a year qualifies an urban household as middle-class. On the other hand, city people who once aspired to own the "big three"—a television, refrigerator and washing machine—have already moved up to DVD players and mobile phones. And with a population of 1.3 billion, the world"s largest, China is a huge market. That is why the world"s **panies, from Coca-Cola to Procter & Gamble, are battling it out in China. Advertisers spent more than $500 million dollars through the first half of the year, estimates market researcher, making China the largest advertising market in Asia after Japan.The prevailing view of many of those advertisers and their agencies is that the Chinese don"t yet get clever or subtle advertising and they prefer a straightforward ad with lots of information. But the April survey of almost 500 people in five China"s largest cities discovered "a savvy urban population, tired of a diet of "boring" ads and hungry to be treated as the sophisticated decision-makers they are." In short, the Chinese appreciation of what makes a good ad is no different from their counterparts anywhere else in the world.1. The 35-year-old woman was dissatisfied with the Haier ad because ______.A. there is too much misleading information about itB. its function is too similar to that of a computerC. its advertisement was too difficult to understandD. it has been advertised in a simple-minded way2. By saying that "**mercials don"t have to talk down to consumers", the author suggests that ______.A. the plain and straight-forward way of advertising should be abolishedB. it is not necessary to take up irony and humor in advertisementC. advertisers are more interested in how to attract the high-class citizensD. those disappearing in the U.S. may be just appropriate in China3. What can we learn about the consumer culture in China?A. It is not as complicated as that outside China.B. It has not been fully understood yet.C. Its influence on advertising is still limited.D. It is one of the most important products of capitalism.4. The author will agree that China"s middle-class households ______.A. are interested in inventive ads instead of simple onesB. earn less than the overseas middle-class householdsC. contribute most to China"s consumer marketD. no longer aspire to own the "the big three"5. The passage mainly intends to discuss ______.A. the most effective ways of advertising in ChinaB. the development of advertising styles in ChinaC. consumers" view on the ads in ChinaD. a misconception on the ads in ChinaSome products respond to consumers" needs; others, like Sony"s airboard, seek to create them. Like sending e-mails from the pool, or curling up in bed with your favorite sitcom. This futuristic **bines the functions of a television, a DVD player and the Internet into a portable tablet the size of a place mat. If it catches on, it could change the concept of being digital at home.At 1.5kg, the airboard is light enough to carry anywhere in the house, and can send and receive data wirelessly from a base station hooked up to home-entertainment equipment. A 10.4-inc. (26-cm) LCD screen delivers vivid moving images or can serve as a digital photo album, and a touch-panel display eliminates the need for a keyboard. Sony, which began selling the device in Japan late last year, praises it as the Walkman of the information age. "It is amazing," **pany president Kunitake Ando, who loftily describes the device as a gateway connecting the home to the outside world and eventually linking all appliances within. "The wireless environment will become **mon pretty soon."I tried out the airboard in my Tokyo apartment, and I have to admit: it"s way cool. First of all, airboarding is easy. I didn"t crack the instruction manual once to get the thing set up—and this is from someone who has trouble finding the "record" button on the VCR. Relaxing on my balcony, I could call up the airboard"s on-screen remote control and start playing video. By pressing another button, I could Net surf or check my e-mail account, while a split screen let me simultaneously watch my movie. The airboard"s base station—the size of a shoe box—doubles as a stand and battery charger. There is a slot for inserting a Sony memory stick, the gum-stick-sized cassette used to store photos and other digital files.But the airboard is not for everybody. At $1,065, it costs as much as a laptop but isn"t meant for **puting. Checking e-mail is easy, but a 56-kbps modem makes for pretty slow surfing. The touch panel is fine for sending quick messages, but pushing the on-screen buttons is tedious for anything。

I was quickly labeled a "brain." I did so well that by the end of senior year I had perfect grades and enough college credits to give up an entire quarter of coursework.But in early June of senior year, the principal called me into his office. He asked me to give a speech at graduation. I was surprised to look at him, my heart thumping. This was the reward for my hard work? I murmured something and fled the office, blaming myself for staying away from physics, a subject sure to have broken up my perfect record.I finally agreed to a compromise. I would share the honor with five other students. I agreed to introduce my friend Judy, who would then give her own, full-length speech.Graduation day soon arrived, I’d been practicing my speech for days, and I had it memorized. The first half hour of the ceremony passed in a blur, and then my moment came. My name was announced. I managed to reach the stage without falling down. I faced my classmates. My voice trembled a little, but mostly it was clear and strong. But within seconds, I was done and heading back to my seat. I accomplished something I’d never dreamed of — I spoke in front of hundreds of people.Although I didn’t realize it at the time, the successful completion of that speech gave me the confidence to take part in class at college, to give oral reports, and to eventually break free of my shyness. I never would have chosen to give a speech at graduation — or ever. But I’m glad I did. Ino longer hesitate when I’m faced with the prospect of doing something I feared. I know it may very well turn out to be one of my shining moments.4.Why was the writer called a "brain"?A.She was the most intelligent student.B.She was the head of her small group.C.She was a bookworm all the time.D.She did more coursework for good grades.5.What can we learn from the second paragraph?A.She ruined her health by studying hard.B.She got the reward as was expected.C.She was grateful for giving a speech.D.She wasn't good at physics at school.6.How did the author feel at the beginning of the graduation speech?A.Excited.B.Moved.C.Scared.D.Embarrassed7.What did the speech bring to the author at last?A.She had nothing to fear in life,B.She won enough college credits.C.She got rid of her sense of shyness.D.She desired to become a speaker.On average, American kids ages 3 to 12 spent 29 hours a week in school, eight hours more than they did in 1981. They also did more household work and participated in more of such organized activities as soccer and ballet. Involvement in sports, in particular, rose almost 50% from 1981 to 1997: boys now spend an average of four hours a week playing sports; girls log hall that time. All in all, however, children’s leisure time dropped from 40% of the day in 1981 to 25%.“Children are affected by the same time crunch that affects their parents,” says Sandra Hofferth, who headed the recent study of children’s timetable. A chief reason, she says, is that more mothers are working outside the home. (Nevertheless, children in both double-income and “male breadwinner” households spent comparable amounts of time interacting with their parents19 hours and 22 hours respectively. In contrast, children spent only 9 hours with their single mothers.)All work and no play could make for some very messed-up kids. “Play is the most powerful way a child explores the world and learns about himself,” says T. Berry Brazelton, professor at Harvard Medical School Unstructured play encourages independent thinking and allows the young to negotiate their relationships with their peers, but kids ages 3 to 12 spent only 12 hours a week engaged in it.The children sampled spent a quarter of their rapidly decreasing “free time” watching television. But that, believe it or not, was one of the findings parents might regard as good news. If they’re spending less time in front of the TV set, however, kids aren’t replacing it with reading. Despite efforts to get kids more interested in books, the children spent just over an hour a week reading. Let’s face it, who’s got the time?8.What does the underlined phrase “the same time crunch” in Paragraph 2 refer to?A.Children have little time to play with their parents.B.Both parents and children suffer from lack of leisure time.C.Children are not taken good care of by their working parents.D.Both parents and children have trouble managing their time.9.In the author’s opinion, a child develops better if .A.he has plenty of time reading and studying B.he is free to interact with his working parentsC.he is left to play with his peers in his own way D.he has more time participating in school activities10.What does the author worry about American kids?A.They are increasingly ignored by their working mothers.B.They are engaged in more and more structured activities.C.They are spending more and more time watching TV.D.They are involved less and less in household work.11.What can we conclude from the text?A.Extracurricular activities promote children’s intelligence.B.Most parents believe reading to be beneficial to children.C.Efforts to get kids interested in reading have been fruitful.D.Most children will turn to reading with TV sets switched off.Move over, helicopter parents. “Snowplow (扫雪机) parents” are the newest reflection of an intensive (强化的) parenting style that can include parents booking their adult children haircuts, texting their college kids to wake them up so they don’t sleep through a test, and even calling their kids’ employers.Helicopter parenting, the practice of wandering anxiously near one’s children, monitoring their every activity, is so 20th century. Some rich mothers and fathers now are more like snowplows: machines moving ahead, clearing any difficulties in their children’s path to success, so they don’t have to suffer failure, frustration (挫折) or lose opportunities.It starts early, when parents get on wait lists for excellent preschools before their babies are born and try to make sure their kids never do anything that may frustrate them. It gets more intense when school starts: running forgotten homework to school or calling a coach to request that their children make the team.Rich parents may have more time and money to devote to making sure their children don’t ever meet with failure, but it’s not only rich parents practicing snowplow parenting. This intensive parenting has become the most welcome way to raise children, regardless of income, education, or race.Yes, it’s a parent’s job to support the children, and to use their adult wisdom to prepare for the future when their children aren’t mature enough to do so. That’s why parents hide certain toys from babies to avoid getting angry or take away a teenager’s car keys until he finishes his college applications.But snowplow parents can take it too far, some experts say. If children have never faced a difficulty, what happens when they get into the real world?“Solving problems, taking risks and overcoming frustration are key life skills,” many child development experts say, “and if parents don’t let their children experience failure, the children don’t acquire them.”12.What do we know about snowplow parenting?A.It appeared before helicopter parenting.B.It costs parents less than helicopter parenting.C.It was a typical phenomenon of the 20th century.D.It provides more than enough services for children.13.What is mainly discussed about snowplow parenting in Paragraph 4?A.Its cost.B.Its benefits.C.Its popularity.D.Its ending. 14.Why does the author mention parents’ taking away car keys?A.To show teenagers are no better than babies.B.To advise teenagers not to treat their cars as toys.C.To advise parents not to buy cars for their teenagers.D.To show it’s appropriate to help children when necessary.15.What’s the possible result of snowplow parenting according to the experts?A.Children lacking problem-solving ability in reality.B.Children mastering more key life skills than parents.C.Children gaining great success in every aspect of life.D.Children meeting no problems or frustration after growing up.Capture spirit of youth“Youth is like the early spring,like the morning sun,like the budding flowers,like the sharp blade fresh off the grinding stone. Youth is the most valuable time of life. "Chen Duxiu,one of the founders of the Communist Party of China,once wrote the Spirit of Youth.16 During this time,habits and interests that will continue for the rest of your life are formed and developed--so it's important to get off to a good start.But what is the spirit of youth It's a time to begin the process of self-reliance and self-motivation. Sure,you might have parents and friends to help you. 17 It builds your character and makes you independent,a necessity to get through the challenges of life. No one can force you to get good grades or get the perfect job-those responsibilities are yours and yours alone. Only you can be the author of your own life.When times get tough,please be persevering. Train yourself to be strong. Tell yourself that you can summon(召唤)the will to overcome whatever obstacles come your way. Anything worth doing isn't easy. 18 In the end,conquering a difficult task is always worth it,and you canthank perseverance for guiding you there.Work hard. There's nothing better than relaxing at the end of a long day,knowing that you did all you could do for yourself,your family and friends,and your community. Be a person that others admire. Do the work that others won't and never complain.

But don't get too 37 (attach) to the technique—telling too many white lies to your child may have more far-reaching consequences than you might have hoped.To examine the impact of parental lying, researchers in Singapore gave 379 adults online 38 (questionnaire). The results suggested that those 39 parents had lied more were now more likely to lie to their own parents—by being lied to, in other words, it seemed they had started to believe that being dishonest 40 (be) morally acceptable.Additionally, if parents are constantly lying to their children, there may potentially be other underlying relational issues 41 (contribute) to problems in adolescence and adulthood. Yes, misleading children might not help their 42 (develop), but there may also be deeper problems that are responsible 43 their difficulty with attention or behaviour.So, next time you think about telling 44 you see as a harmless white lie to keep your child quiet or get them into bed, 45 (think) again. It may save you some time—but, in the long run, it's probably not worth it.四、完成句子46.玛丽发现丈夫躺在地上,于是她拨打了120。

GRE阅读考试资料During experiments at the Bimini Biological Research Station in the Bahamas, researchers Eric Stroud and Michael Hermann dropped a small mag in the water beside a shark。
The presence of the mag elicited a distinct reaction from the fish -- they darted away from it。
Why the intense reaction? The interaction of salt water and charged metals produces a weak electrical field。
When a shark es close to that field, the field seems to disrupt the sharks‘ special sixth sense,electroreception。
Many shark species have pores dotted around their snouts called ampullae of Lorenzinithat detect minute changes of electricity in the seawater, up to one-billionth of a volt。
These electrical impulses e from the tiniest muscle contractions of other aquatic life forms -- or people -- and are carried through the ions in the salt water。

Read the passages carefully. Then answer the questions in the fewest possible words(not exceeding 10 words). Remember to rewrite the answers on the Answer Sheet.Questions 61 to 66 are based on the following passage:Centuries ago, man discovered that removing moisture from food helps to preserve it, and that the easiest way to do this is to expose the food to sun and wind.Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. The methods used vary, but in general, the fruit is spread out on trays in drying yards in the hot sun. In order to prevent darkening, pears, peaches and apricots are exposed to the fumes of burning sulphur before drying. Plums, for making prunes, and certain varieties of grapes for making raisins and currants, are dipped in an alkaline solution in order to crack the skins of the fruit slightly and remove their wax coating, so increasing the rate ofdrying.Nowadays most foods are dried mechanically. The conventional method of such dehydration is to put food in chambers through which hot air is blown at temperatures of about 110℃ at entry to about 43℃ at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients are dried separately and then mixed.Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them. Usually it is just a case of replacing the dried-out moisture with boiling water.Questions:61. Fruit is sun-dried generally on________.62. Why are sulphur fumes used before drying some fruits?63. Where are vegetables commonly dried nowadays?64. If soup requires recognizable pieces of meat, they are________.65. Dried foods are often used by________, ________and________.66. Why do housewives like dried foods?Questions 67 to 72 are based on the following passage:Hollywood writers honor Coppo la, “Splendor”Sunday, February 22, 2004 Posted: 9:56 AM EST (14:56 GMT)LOS ANGELES, California (Reuters) —Hollywood’s screenwriters Saturday snubbed the final installment of the highly acclaimed Lord of the Rings trilogy and instead awarded a key prize to a low-budget film based on a comic book writer.American Splendor, which revolves around thetravails of comics connoisseur Harvey Pekar, won theWriters Guild of America Award for best adaptedscreenplay, while writer / director Sofia Coppola’s Lost inTranslation, about a pair of mismatched Americanslanguishing inTokyo, nabbedthe trophy fororiginalscreenplay.TheAmericanSplendorscreenplay waswritten by thefilm’s directors,Robert Springerand ShariSpringer Berman, who were not present at the awards. The Writers Guild of America Awards were handed out simultaneously in Los Angeles and New York.Coppola said she was excited to be honored by the union.“I find it difficult to write, so it’s very encouraging and exciting to get an award,” C oppola told Reuters after the event.Coppola’s competition was Gurinder Chadha, Paul Mayeda Berges and Guljit Bindra for Bend It Like Beckham, Steven Knight for Dirty Pretty Things, Irish director Jim Sheridan and his daughters Naomi and Kirsten for In America, and first-time writer / director Tom McCarthy for The Station Agent.The other adapted screenplay nominees were director Peter Jackson, Fran Walsh and Philippa Boyens for The Lord of the Rings: The Return of the King, Anthony Minghella for Cold Mountain, Brian Helgeland for Mystic River, and writer / director Gary Ross for Seabiscuit.Coppola, Knight and the Sheridans will vie for the Academy Award next week, along with the writers of The Barbarian Invasions and Finding Nemo.Apart from Cold Mountain, all the Writers Guild of America adapted screenplay contenders will compete for the Oscar, along with the Brazilian drama City of God.In the last 12 years, eight of the Writers Guild of America adapted screenplay winners and seven of its original screenplay winners have gone on to Oscar glory.Lost in Translation has already picked up three Golden Globes—an Oscar bell-wether—including best screenplay. The Lord of the Rings: The Return of the King, which has 11 Oscar nominations, has collected four Golden Globes and prizes from Hollywood’s producers and directors guilds.Questions:67. What does American Splendor mainly write about?68. Sofia Coppola’s Lost in Translation won the Writers Guild of America Award for________.69. The Writers Guild of America Awards were offered at the same time in________and________.70. How did Coppola feel about her getting the award?71. List at least 3 movies that competed with Lost in Translation.72. How many Writers Guild of America screenplay winners have gone on to Oscar glory in the last 12 years?Questions 73 to 78 are based on the following passage:The need for a surgical operation, especially an emergency operation, almost always comes as a severe shock to the patient and his family. Despite modern advances, most people still have an irrational fear of hospitals and anaesthetics.In the early years of last century there was little specialization in surgery. A good surgeon was capable ofperforming almost every operation that had been devised up to that time. Today the situation is different. Operations are now being carried out that were not even dreamed of fifty years ago. The heart can be safely opened and its valves repaired. Clogged blood vessels can be cleaned out, and broken ones mended or replaced. A lung, the whole stomach, or even part of the brain can be removed and still permit the patient to live a comfortable and satisfactory life.The scope of surgery has increased remarkably in 20th century. Its safety has increased too. Deaths from most operations are about 20% of what they were in 1910 and surgery has been extended in many directions,for example to certain types of birth defects in newborn babies, and, at the other end of the scale, to life-saving operations for the octogenarian.The hospital stay after surgery has been shortened to as little as a week for most major operations.Many developments in modern surgery are almost incredible. They include the replacement of damaged blood vessels with simulated ones made of plastic; the replacement of heart valves with plastic substitutes; the transplanting of tissues such as the lens of the eye.One of the most revolutionary areas of modern surgery is that of organ transplants. Until a few years ago, no person, except an indentical twin, was able to accept into his body the tissues of another person without reacting against them and eventually causing death. Recently, however, it has been discovered that with the use of x-rays and special drugs, it is possible to graft tissues from one person to another which will survive for periods of a year or more. Kidneys have been successfully transplanted between non-identical twins. Heart and lung transplants have been reasonably successful in animals, though rejection problems in humans have yet to be solved.“Spare parts” surgery, the simple routine replacement of all worn-out organs by new ones, is still a dream of the distant future. As yet, surgery is not ready for such miracles. In the meantime, you can be happy if your doctor says to you,“Yes, I think it is possible to operate on you for this condition.”Questions:73. Most people are afraid of being operated on in spite of________.74.A patient can still live a comfortable and satisfactory life even after the removal of________.75. Today deaths from most operations are about ________of what they were in 1910.76. What’s the main difficulty in organ transplanting?77. Is “spare parts” surgery possible now?78. You can be happy if your surgeon can operate because it means________.Questions 79 to 84 are based on the following passage:Sales of anti-ageing skin treatments have reached a new high as British women try to stay younger longer (writes Joanna Bale). But according to a recent survey of those aged between 35 and 55 there are significant regional variations in annual spend on these cosmetics.While the average woman thinks costs of £200 a year acceptable—almost treble the £75 of three years ago—some fork out £500, according to the survey of over 2,000 women nationwide by the beauty company Olay.Brows will wrinkle at the differences in yearly spend on anti-ageing treatments across major cities: the ladies of Edinburgh spent least, just £50 a year, while those in Leeds spend most, at a staggering £500. London women most commonly spend £200 annually, and those in Manchester give themselves a modest yearly budget of £100.Equally surprising are the results among 40-somethings. Single women spend the least on indulging their desire for facial rejuvenation, with only 25 per cent forking out on skincare products or treatments. This figure rises to just over 31 per cent of married women and a similar figure for those who are unmarried with partners.By far the biggest spenders are the 50 per cent of divorcees who feel the pressure to invest heavily in their facial futures.The survey highlighted two groups who spend significant sums on enhancing their appearances—“Sindies” (single income now divorced), and women in their 40s who use their looks to get ahead.The survey also found that although women wanted to “de-age” they had a holistic view of beauty and embraced a realistic and natural approach to looking good.Questions:79. Compared with that of three years ago, the average British woman’s annual spend on cosmetics hasalmost________.80. Women in________spend most on cosmetics according to the survey.81. The ladies of Birmingham as well as those in ________spend £100 a year on antiageing treatments.82. ________and________spend more on indulging their desire for facial rejuvenation than single women.83. Enhancing appearances plays an important role in the life of________and________.84. After reading the passage, what do you learn about the sales of anti-ageing skin treatments now in Britain?Questions 85 to 90 are based on the following passage:It is hard to get any agreement on the precise meaning of the term “social class”. In everyday life, people tend to have a different approach to those they consider higher or lower than themselves in the social scale. The criteria we use to “place” a new acquaintance, however, are a complex mixture of factors. Dress, way of speaking, area of residence in a given city or province, education and manners all play a part.In ancient civilizations, the Sumerian, for example,social differences were based on birth,status or rank,rather than on wealth. Four main classes were recognized. These were the rulers, the priestly administrators, the freemen (such as craftsmen,merchants or farmers) and the slaves.In Greece, after the sixth-century B.C., there was a growing conflict between the peasants and the landed aristocrats, and a gradual decrea se in the power of the aristocracy when a kind of “middle class” of traders and skilled workers grew up. The population of Athens,for example, was divided into three main classes which were politically and legally distinct. About one-third of the total were slaves, who did not count politically at all, a fact often forgotten by those who praise Athens as the nursery of democracy. The next main group consisted of resident foreigners, the “metics”, who were freemen, though they too were allowed no share in political life. The third group was the powerful body of “citizens”, who were themselves divided into subclasses.In ancient Rome, too, a similar struggle between the plebs, or working people, and the landed families was a recurrent feature of social life.The medieval feudal system, which flourished in Europe from the ninth to the thirteenth centuries, gave rise to a comparatively simple system based on birth.Under the king there were two main classes—lords and “vassals”, the latter with many subdivisions. The vassal owed the lord fidelity, obedience and aid, especially in the form of military service. The lord in return owed his vassal protection and an assured livelihood.In the later Middle Ages, however, the development of a money economy and the growth of cities and trade led to the rise of another class, the “burghers” or city merchants and mayors. These were the predecessors of the modern middle classes. Gradually high office and occupation assumed importance in determining social position, as it became more and more possible for a person born to one station in life to move to another. This change affected the towns more than the country areas, where remnants of feudalism lasted much longer.Questions:85. List at least three common criteria for tel ling a person’s social position.86. What were the four main classes in the Sumerian civilization?87. Slaves in Greece in the sixth century B.C. were not________significant.88. The struggle between the plebs and the landed families was a________feature of social life.89. The metics,one of the three classes of Greece, consisted mainly of________.90.

A brand isn’t just a logo on a shirt or an ice-cream van. It’s much more than that. To be successful a brand has to have rational characteristics—(101)ie, it has to be competitive on price or quality or service, and it has to have a “personality” that charms and seduces.It is a mix of emotional factors,such as “Do I like it?” and “Is it me?” and rational factors such as,“Is it cheaper or better or quicker?”(102)Getting things in balance is tricky,and that’s why so many brands don’t succeed.Just let’s look at all the ways brands can fail. Brands are vulnerable to fashion. Fizzy drinks such as Coke and Pepsi are now being attacked by stimulation drinks such as Red Bull. Fast food brands are threatened by salads and other “lite” foods. McDonald’s has recently been in real trouble.Brands are also vulnerable because they get cocky,arrogant and out of touch. They think the y know best and don’t change with the market—like the Gap, Levi’s and Marks & Spencer brands who learnt their lesson the hard way.(103)In fact, even the people who create brands can’t really control them or even predict how people will use them. Not one single mobile phone company anywhere in the world anticipated the growth of texting.The companies involved in the new 3G phone technology are still holding their breath because they don’t know whether it will take off or not. And if it does take off, they won’t know how and in what direction until the market tells them. It’s a huge gamble.Range Rover was the first Sport Utility Vehicle, but Land Rover never completely understood the concept that it had inspired. Range Rover has spent much of its life span trying to catch up with the trend that it serendipitously created. (104)Organic foods。

xxxxKeywords:Changjiang (Yangtze River)Estuary Bathymetric change DredgingRiver-mouth shoal Sediment dischargeEstuarine morphodynamics Time seriesThe mouths of major rivers in the world have always been important waterways and as a result,subject to signi ficant human intervention.Therefore,it is necessary to understand the coupling of natural processes and human intervention in the sediment movement and deposition to determine long-term morphodynamic evolution in the mouth regions of major rivers.A multivariate technique was used to analyze high-resolution bathymetric data from the North Passage of Changjiang (Yangtze River),which is the vital shipping channel in the mouth region and for the entire Changjiang waterway.Our findings show that there are two modes of bathymetric changes.The first mode represents 85%of the variability,which includes the deposition in the peripheral groin fields along the shipping channel and deepening of the shipping channel,which is primarily due to the channel maintenance.The second mode represents 6%of the variability of the river-mouth shoal (seaward migration and size reduction),attributable to the declining sediment discharge of the Changjiang due to the Three Gorges Dam,and the enhancement of the ebb flow as the result of dredging.©2013Elsevier B.V.All rights reserved.1.IntroductionEstuaries are located at the junctions of rivers and the sea.They are complex systems in which exchanges of fluvial and marine sedi-ments take place (Wright and Coleman,1974).Estuaries possess valuable natural and human resources such as biodiversity and waterway;they have therefore been the foci of several scienti fic en-quiries.Many estuaries in the world have been subject to human in-tervention,such as the excavation for aggregates and dredging for waterway (La fite and Romaña,2001;Blott et al.,2006;Benedet and List,2008;Talke et al.,2009;Jiang et al.,2012),and no longer “be-have ”naturally.The examples can be seen in many estuaries around the world.In the past 200years,because of the navigational needs,the channel in the Ribble estuary in N.England has been dredged,leading to deposition in the estuary especially in the upper intertidal zone (van der Wal et al.,2002).Due to the construction of retaining walls and dredging of the approaching channels,in the past 150years the volume of the Mersey Estuary decreased by 0.1%or 1million m 3(Lane,2004).After channel improvements in the Columbia River Estuary,the tidal prism decreased,leading to the loss of river-mouth wetland and habitat (Sherwood,et al.,1990).Dredging and dumping activities in the Ems Estuary altered the estua-rine dynamics and sedimentation process,causing the upriver displace-ment of the Estuarine Turbidity Maximum (ETM)zone (De Jonge,1983;Talke et al.,2009).Accumulation of a large amount of silt and fine sand occurred in the middle reaches of the Lune Estuary in the last 100years due to the construction of retaining walls (Spearman et al.,1998).In the Anthropocene,many estuaries face declining sediment load,river engineering modi fications,and the relative sea-level rise (Syvitski et al.,2005).There have been studies on estuarine sediment transport (Wright,1977),estuarine morphodynamic modeling (Karunarathna et al.,2008;van der Wegen et al.,2010;Rossington et al.,2011),estuarine tidal flat reclamation (van Proosdij et al.,2009),and channel dredging and regulation (Stark,2006;van Proosdij et al.,2009).Yet,little has been focused on how human interventions affect estuarine changes and evolution.Based on studies of the river catchments,many large riv-ers in the world have been regulated (Nilsson et al.,2008),but due to the complexity in the estuarine hydrodynamics,even with human regula-tion,it is still unclear how the regulations affect estuaries.Changjiang (Yangtze River)is the largest river on the Eurasia con-tinent whose estuary is the largest in China (Fig.1A).In the lower reaches of the Changjiang,the river channel sequentially bifurcates at four islands,Chongming,Hengsha,Changxing and Jiuduansha Shoal,forming a 3-tiered branching meso-tidal estuary that has 4openings to the East China Sea (Fig.1B,C).At the mouth of the Changjiang the average tidal range is 2.67m and flow rate is 1m/s.Since June 2003,when the upper reaches of the Changjiang beganGeomorphology xxx (2013)xxx

l s e v i e r.c o m /l o c a t e /g e o m o rp hto be impounded by the world's largest Three Gorges Dam (TGD),the sediment load rapidly decreased (Fig.1D),leading to localized ero-sions in the mouth area (Yang et al.,2007;Dai et al.,2008a,2011).Since 1998the North Passage (N.Passage),where the main ship-ping channel of the Changjiang waterway is located,has been contin-ually dredged from the average depth less than 7m to the present day 12.5m using trailing-suction hopper dredgers.For the mainte-nance of the dredged shipping channel,nineteen T-shaped groins were constructed off two dikes on both flanks along the shipping channel (Fig.1C).On each side the dikes were 49.2and 48km long,respectively.They were designed to maintain the outer perime-ter of the N.Passage.The dikes and groins are emerged at low tide and submerged at high tide.Their first intended function was to sta-bilize the shipping channel.Their second intended function was to prevent sediment entrained by waves on the tidal flats on both sides of the N.Passage entering the channel.The third intended function was to redirect the peripheral ebb flows into the main chan-nel to strengthen the ebb flow in the channel and also to ensure the ebb flow dominance in the channel so that the flow field in the chan-nel maintains the trough-shaped cross-sectional geometry.The aver-age length of the groins is 2km.There were ten groins on the north side and 9on the south side.The total length of all the groins was about 30km.This channel maintenance project is by far the largest estuarine hy-draulic engineering endeavor in China whose scale and regional in flu-ence is comparable to that of the Dutch Delta Works,which is located near the con fluence of the Rhine,Maas and Schelde.Although the N.Pas-sage Improvement Project and the Delta Works are located in different regions and in river systems with contrasting hydrodynamic regimes,they share similarities in the scale of engineering work,the impact on the immediate estuarine environment,and their far-reaching in fluence on the socio-economical well-being of thepopulation.Fig.1.Geographic information of the study area including (A)the map of China,which

–xxxTheoretically,the TGD in the distal upper reaches of the Changjiang and the proximal shipping channel engineering activities in the estuary would affect the estuarine hydrodynamics and produce pronounced ef-fects.Furthermore,the effects of the proximal channel dredging and the groinfields on the morphodynamics in the N.Passage are not well studied.We hypothesize that these two major factors,the distal TGD and the proximal channel maintenance engineering will affect the sedimentation the North Passage.Therefore,this study used quarterly high-resolution bathymetric survey data since1998to examine the spa-tial and temporal variability of the bathymetry along the N.Passage.The goal is to determine the combined influence of hydrodynamics and human intervention on the N.Passage and further distinguish the rela-tive significance of the proximal and distal influence.This is an interest-ing aspect that is of wider international significance.2.Materials and methodsThe scarcity of high-resolution bathymetric survey data that cover a long time span makes it difficult to quantify long-term sediment morphodynamics in estuaries.Since January1998when the channel deepening and maintenance engineering project began,the N.Passage was surveyed on a semi-quarterly basis every year by the Changjiang Estuary Waterway Administration Bureau(CJWAB),Ministry of Trans-portation(data available at )using dual-frequency echo sounders and GPS positioning.The vertical error in the depth sur-veys was0.1m.The surveyed raw data were made into1:10,000and 1:25.000bathymetric charts suing AutoCad software(Table1).The water depths on channel cross-sections were spaced1km apart,having 50m intervals along each cross-section on the1:10,000-scale chart,and the cross-sectional spacing was the same but the depth-intervals along each cross-section was250m on the1:25,000-scale chart.Every square kilometer on each chart should contain8–40surveyed data points.This study collected45bathymetric charts between August1998and August 2011in February,May,August,and November each year.Subsequently on the ArcGis9.3platform using Kriging interpolation method each data set was gridded into charts of200×200m resolution.Each chart contained11,255interpolated data points so that cross-comparisons could be made between charts of different times.This study also acquired measuredflow data(source:CJWAB)in a 25-hour tidal cycle at5locations in the N.Passage in the months of June1999,and August2002,2005,2007,2008and2011,respectively (Fig.1C,Table2).The measured tidal cycles all coincided with the spring tide.In addition,monthly records of suspended sediment data since1955monitored at Datong station,which is located beyond the tidal limit of the Changjiang(Fig.1A),were also acquired(data available at ).At each hydrographic station,the coefficient offlow dominance (defined as tidal excursion during the ebb divided by the sum of tidal excursions of the ebb andflood)was calculated(Simmons,1955) as follows:A¼Q eQ eþQ fÂ100%ð1Þwhere A is the dominance coefficient,Q e is the unit width ebb vol-ume,and Q f is the unit widthflood volume.When the ebbflow is dominant,A>50%,and vice versa.To quantify the volume change of the N.Passage so that the sedi-ment change could be deduced,ArcGIS was used as the platform for data assimilations.Generally in the deltaic region of the Changjiang, the estimate of the volume of the river channel is estimated from the bathymetry below the0m elevation.The area of the tidalflat is considered within elevation range between0and−2m.To compre-hensively represent the average channel depth and dredged naviga-tional depth,−8m elevation was used.Therefore,for each dataset the volumes of the river channel below−0m,−8m and above−2m,and the volume of the river-mouth shoal were estimated.The depth values along the thalweg location were extracted and their anomalies(deviations from the mean)were subsequently calculated at each location for each data set.EOF(Empirical Orthogonal/Eigen Function)is eigentechniques that can permit us to extract information from large datasets.The advantage of EOF analysis is that a set of intercorrelated variables can be decomposed into a set of statistically independent variables. Eigenanalysis separates the temporal and spatial dependence of the data,considering data as a linear combination of products of corre-sponding functions of time and space(Dai et al.,2008b,2010).Obvious-ly,the aim of EOF is tofind a relatively small number of independent variables that describe as much of the original information as possible. This technique has been widely used in the study of estuarine mor-phodynamics and sediment dynamics(Zarillo and Liu,1988;Emery and Thomson,2001;Lane,2004;Liu and Lin,2004;Dai et al.,2008b; Liu et al.,2009;Dai et al.,2010).Here,all the bathymetric data sets were standardized to form a single matrix XX¼X1…X NðÞwhere each X N represents a single grouped observation of the M vari-ables and X is an M×N data matrix.M is a spatial point,and N is the ob-served time.By definition,the EOFs are the eigenfunctions of the standardized covariance matrix S,which is given by S=XX′.Based on singular value decomposition of the matrix S,the eigenvaluesλ(λ1,λ2,…,λM)of S and spatial patterns(V)can be obtained.Thereafter,the time series de-scribing the loadings(T)is calculated by T=V′X.Subsequently,eigenvaluesλ(λ1,λ2,…,λM)can be rearranged from largest to smallest in order,the variance contribution of eachTable1Surveyed water depth data in the North Passage,Changjiang

2001)the depth of the shipping channel was deepened to 8.5m.The first stage only affected the upper part of the N.Passage where the dikes and groin fields were put in place and the navigational channel was deepened (Fig.2A).However,there was erosion of over 1m in the channel in the lower part,and minor erosion of less than 0.5m appeared in the middle part of the N.Passage.There was deposition over 2m in the groins on the north side of the channel (Fig.2A).The capacity (volume be-tween 0m and the channel floor)of the channel was enlarged by about 214.8×106m 3(Table 3).In the interim period between the 1st and 2nd stages,there was minor deposition.The formerly dredged channel was back-filled by about 145.7×106m 3(Fig.2B,Table 3).During the 2nd stage (May 2002–February 2005),the channel depth reached 10m and the dikes and groin fields were extended for the en-tire shipping channel and the groins in the 1st stage on the north side were lengthened (Fig.2C).During this stage,the channel continued to be deepened and simultaneously deposition occurred in between groins,in which the average vertical accumulations exceeded 1m (Table 3).Consequently,the channel capacity actually decreased by 125.6×106m 3.In the interim period between the 2nd and 3rd stages,channel deepening took place in the lower part of the N.Passage and deposition occurred in the upper part (Fig.2D).During the 3rd stage (August 2006–March 2010),the water depth reached 12.5m and the deposition rate of about 4.5cm/year in the groin fields was similar to that during the previous stage,but themain channel was deepened further (Fig.2E,Table 3).The channel ca-pacity remained unchanged (Table 3).After the completion of the 3rd stage,between February 2010and August 2011,the N.Passage was back-filled by 80.9×106m 3.The channel capacity below 0m was de-creased by about 15%in comparison with that before the dredged en-gineering in August 1998.In the meantime,deposition continued to occur in the groin fields.The patterns in bathymetric change showed patchy deposition (Fig.2F)similar to the interim period between the 1st and 2nd stages (Fig.2B).During each stage,immediately after dredging,dredgers maintained the shipping channel.In general,the engineering efforts deepened the navigational channel and the groin fields trapped sediment as expected.After the completion of the engi-neering project,the sediment continued to in fill the groin fields but the dredged channel began to be back-filled,starting in the middle section and,then extended down-river (Fig.2F).In the past 13years,the capacity of the N.Passage has been on a decreasing trend,punctuated by seasonal fluctuations (Fig.3A).On average,the mean yearly capacity decreased by 17.2×106m 3.How-ever,in the main shipping channel where the depth was greater than −8m,the capacity increased (especially in the 3rd engineering stage)by 14.8×106m 3(Fig.3B).It is notable that although the alter-nate phenomena of deposition in the flood season and erosion in the dry season were not as pronounced as observed previously (Yun,2004),seasonal fluctuations were still presented in our data.More-over,based the different digital navigational charts,patterns of sedi-ment exchange between the tidal flat and channel can be found (Yun,2004).Here,the opposing accumulation/removal trend be-tween the groin fields and the channel (deeper than −8m)suggests some sediment exchange between the two still existed.During the 13-year period that spanned the engineering project,the depth anomaly along the channel thalweg reveals that the firstFig.2.Bathymetric changes (depth of later time minus that of the previous time)in the follow periods:(A)Aug.1998–May 2001,(B)May 2001–May 2002,(C)May

more effective in deepening the channel.However,although there were continued dredging efforts,the channel always became back-filled after the completion of each stage (Fig.3C).The river-mouth shoal in the N.Passage is a characteristic deposi-tional feature common in estuaries,whose changes are well re flected in the depth anomaly (Fig.3C).In the beginning of the first engineer-ing period (September 1998–May 2001),the shoal appeared to be symmetrical in the axial direction,having a height as much as 2m above the channel floor and a wide (about 20km)base (red curves,Fig.3C).During the 13-year period,the volume of the shoal decreased by more than twofold (Fig.3D).It is notable that in the course of the declining trend,the shoal always grew larger during each engineering stage,probably fed by the sediment plume during dredging.In the post-engineering period (May 2010–August 2011),the shoal was lo-cated 18km down river from the pre-engineering position,having a greater height about 3m and narrower (about 5km)base in the axial direction (blue curves,Fig.3C).The morphology of the shoal was changed from having gentle slopes during the pre-engineering period to having steeper slopes during the third engineering period (Fig.3C).3.2.Empirical orthogonal function/eigenanalysis of the bathymetric changesThe major morphology of the Changjiang Estuary has remained the same since the 1954deluge (Yun,2004).Therefore,our analysis is only on the small-scale depth changes in the N.Passage using the EOF technique.The EOF results show that the dataset was highly correlated and that the first two eigenmodes explain 91%of the correlations (stan-dardized covariance)of the time-and-space correlated bathymetric changes.Therefore,we present only the first two modes;the remain-der is considered as being insigni ficant (Zarillo and Liu,1988;Emery and Thomson,2001).The eigenvectors of the 1st mode,which explains 85%of the corre-lations,were contoured with the groin fields superimposed (Fig.4A).It re flects the dichotomy in the bathymetric changes along the N.Pas-sage due to the engineering project.On one hand,along the thalweg(below −8m depth)the water became deeper (negative values)due to dredging (Fig.2).On the other hand,along the flanks of the channel in the groin fields and on the tidal flats (above −2m depth),the depths became shallower (positive values)due to deposi-tion (Fig.2).The contoured patterns also indicate that major accumu-lation occurred in the northern groin field during the 1st stage and in the southern groin field since the 2nd stage (Fig.4A).The temporal pattern of this mode is represented by the eigenweighting curve (Fig.4B).The periods of the 3stages of the engineering project are in-dicated by three dashed rectangles,and the time frame when the TGD became operational is indicated by dotted rectangle.In essence,this curve is a mirror re flection (opposite)of the channel capacity de-crease (Fig.3A)such that a weak yet signi ficant negative correlation exists between the 1st mode eigenweightings and the capacity below —0m (n =45,r =−0.25,p b 0.1).Therefore,the first eigen-mode primarily describes the decrease in channel capacity over the 13-year period in which the main channel was deepened by human efforts in three incremental stages while sediment accumulated be-tween the groins and on the tidal flats along the channel.The second eigenmode explains 6%of the correlations.The contoured eigenvectors show positive values are along the thalweg (Fig.4C).The temporal characteristics of this mode are represented by the eigenweighting curve that shows secular decline (Fig.4D).The same trends of volume decrease of the river-mouth shoal (Fig.3D)and the decline of the suspended sediment discharge of Changjiang recorded at Datong (Fig.1B)suggests that this mode is probably attributed to both.In fact,linear regression analysis shows that a highly signi ficant correlation (r =0.91,p b 0.001)exists between the 2nd mode eigenweightings and the mean yearly-suspended load at Datong.Concurrently signi ficant linear correlation also exists be-tween the 2nd mode eigenweightings and the volume of the river-mouth shoal (r =0.86,p b 0.001).It is also noted that the zero-crossing of the 2nd eigenweighting curve corresponds to the time when the TGD began operation (Figs.1D,4D).3.3.Variations of flow

point,not all stations are available (Table 2).Data from the time points that coincided with the engineering stages are plotted with dashed lines.When comparing the values in June 1999(pre-engineering)and in August 2011(post-engineering),one can see that the overall ebb-flow dominance has dropped by 5%along the N.Passage.It is also worth noting that the ebb-flow dominance increased at Cs3,and exceeded that at Cs1.This could explain why the river-mouth shoal was pushed down river from Cs1to Cs3during the 13-year period.The relatively weak ebb-flow dominance in the landward bottom estuarine circulation is probably located at Csw after the engineering project.4.Discussion and conclusionOur findings show that the engineering project to deepen the thalweg and the construction of the T-shaped groin fields along the N.Passage to improve and maintain the navigation channel is the main cause for the predominant form (85%)of bathymetric changes in N.Passage.Throughout the course of the engineering project,the bathy-metric changes appeared in two opposite and yet related patterns.Within the navigational channel (water depth deeper than −8m)during the engineering stages,the depth increased due to dredging.The combined effect of the groins and the dyke prevented sediment from entering the N.Passage and also reinforced the ebb flow (Fig.1B).However,in the interim periods between two engineering stages,the dredged channel got back-filled and the depth became shallower.Eventually,the continual dredging did increase the capacity of the North Passage below the depth of −8m.The groins on the other hand,trapped sediment and caused deposition in the groin fields and on the tidal flats outside the channel in areas shallower than −2m depth.Two factors contributed to the second most important form of bathymetric changes (6%of the data variability)that occurred in the thalweg of the N.Passage.The first one is the declining sediment sup-ply to the estuary that is directly linked to the operation of the TGD.Since its operation in 2003,the amount of sediment trapped by TGD was 124×106t in 2003,102×106t in 2004,151×106t in 2005,and 196×106t in 2010(data available at ).This in-duced an obvious decrease in sediment discharge into the Changjiang Estuary from 420×106t/y during the last 50years to 150×106t/y in recent years (Fig.1D).Meanwhile,suspended sediment concentra-tion around the shoal area in the Changjiang Estuary decreased from 0.34kg/m 3in 1999to 0.28kg/m 3in 2009(Dai et al.,2012).The other factor is the down-river migration and volumereductionFig.4.Results of the EOF analysis showing (A)contoured eigenvectors of the first mode,(B)the first mode eigenweightings,(C)contoured eigenvectors of second
