高三英语读后续写素材积累28——声音篇(1)乐音1.The melody of the violin drifted through the air, softly caressing every soulpresent, as if nature itself were humming a soothing lullaby.小提琴的旋律在空中飘荡,温柔地抚慰着在场的每一个人,仿佛大自然本身在低吟一首安神的摇篮曲。
2.With each note resonating in the vast hall, the concertgoers found themselvestransported to a realm of pure joy, where worries seemed to dissolve.随着每一个音符在大厅中回荡,听众们发现自己被带到了一个充满纯粹喜悦的领域,那里的烦恼似乎都烟消云散了。
3.The pianoforte’s gentle touch painted the air with hues of emotion, leaving no oneuntouched by its profound melody.钢琴轻柔的触键在空气中绘出了情感的色彩,其深沉的旋律无人不为之动容。
4.It was as if the music had a life of its own, weaving intricate patterns of joy andsorrow, inviting all to participate in its symphony of emotions.仿佛音乐有着自己的生命,编织着喜悦与悲伤的复杂图案,邀请每个人参与这场情感的交响乐。
5.Had it not been for the symphony’s ethereal harmonies, the night would haveremained a mere blank canvas, devoid of color and depth.如果没有交响乐那超凡脱俗的和声,这个夜晚就会像一张空白的画布,缺乏色彩与深度。
Unit 4Task 1【答案】1) He stood up and rang the bell.2) He wanted to make sure that the driver heard him.3) The conductor came and shouted at him.4) The landlady told him that’s the signal for the driver to go on and only the conductor was allowed to ring the bell twice. That’s why the conductor got so annoyed.【原文】A strange thing happened to Henri yesterday. He was on a bus and wanted to get off. So he stood up and rang the bell. To make sure the driver heard him he rang it twice, but the bus didn’t stop, and the conductor came and shouted at him.The conductor was so annoyed, and spoke so fast, that Henri didn’t understand a word. The bus stopped at the next bus stop and Henri got off. As he got off he heard someone say, “I think he’s a foreigner.”When Henri got home, he told his landlady about the incident.“How many times did you ring the bell?” she asked.“Twice,” said Henri.“Well, that’s the signal for the driver to go on,” his landlady explained. “Only the conductor is allowed to ring the bell twi ce. That’s why he got so annoyed.”Henri nodded. “I see,” he said.Task 2【答案】1) T, 2) F, 3) F, 4) F, 5) T, 6) T【原文】The Taylor family, who live in North London, are planning to spend a day in Norwich. They can’t agree how to get there.Mr. Taylor: I don’t want to drive all that way. Let’s go by train.Mrs. Taylor: But that’s so expensive. It’s much cheaper for a family to go by car.Peter: Why not try the coach? It’ll be cheaper than the train, and Daddy won’t have to drive.Alison: But I’ll be sick! I hate traveling by coach.Mrs. Taylor: Which is the quickest way to get there?Mr. Taylor: Well, it’ll take at least three hours by car.Peter: No, it won’t. Not if we take the motorway out of London.Alison: I’m sure there’s a fast train service.Mrs. Taylor: But we’ll have to get to Liverpool Street first. And then there’s the tube fares at this end, and bus or taxi fares at the other.Alison: And the coach station is at Victoria, so that’s an extra journey too.Mr. Taylor: I think there are som e special family rail fares. Perhaps that’ll be the cheapes t way.Peter: But it won’t be the most convenient.Mrs. Taylor: Why don’t we check all the facts and then decide?Peter: OK.Task 3【答案】A.of, without, of,for, to, by, to, to, intofrom, withon, in, around, aboutB.1) school buses are used only when children live more than a mile from the school. When their children are too young to walk that far, their mothers take turns driving them to school.2) they can save gasoline and it is easier for them to find parking places3) too many cars are on the road and have created many problems【原文】The United States is full of automobiles. There are still many families without cars, but some families have two or even more. However, cars are used for more than pleasure. They are a necessary part of life.Cars are used for business. They are driven to offices and factories by workers who have no other way to get to their jobs. When salesmen are sent to different parts of the city, they have to drive in order to carry their products. Farmers have to drive into the city in order to get supplies.Sometimes small children must be driven to school. In some cities school buses are used only when children live more than a mile from the school. When the children are too young to walk that far, their mothers take turns driving them to school. One mother drives on Mondays, taking her own children and the neighbors’ children as well. Another mother drives on Tuesdays, another on Wednesdays and so on. This is called forming a car pool. Men also form car pools, with three or four men taking turns driving to the place where they all work.More car pools should be formed in order to put fewer automobiles on the road and use less gasoline. Parking is a great problem, and so is the traffic in and around cities. Too many cars are being driven. Something will have to be done about the use of cars.Task 4【答案】1) T, 2) F, 3) T, 4) F【原文】Mr. Fine: Can anyone in the class explain some differences between a zip code and an area code?Mary: Both of them are numbers.Mr. Fine: That’s how they are alike. But how are they different?Mary: A zip code is for mailing letters. An area code is for making phone calls,Mr. Fine: What kind of phone calls?Mary: Long distance calls.Mr. Fine: All right. And what is a zip code?Mary: When I write a letter to my friends in New York City, I write 10027 on the envelope.That’s their zip code. I have some other friends i n New York City, but their zip code is10003.Mr. Fine: In a big city there are different zip codes for different parts of the city. What about area codes?Mary: Sometimes a whole small city has the same area code.Mr. Fine: That’s right. And sometimes a whole state has the same area code if it doesn’t have many telephones. For example, the area code for the whole state of Arizona is 802.Mary: But New York State has millions of telephones, so it has more than one area code.Task 5【答案】A.1) c, 2) b, 3) a, 4) c, 5) a, 6) c, 7) b, 8) cB.1) would have got up on time2) would have woken up James3) would have been on the plane that crashed4) would have lost his life in the crash【原文】James wrote a play for television about an immigrant family who came to England from Pakistan, and the problems they had settled down in England. The play was surprisingly successful, and it was bought by an American TV company.James was invited to go to New York to help with the production. He lived in Dulwich, which is an hour’s journey away from Heathrow. The flight was due to leave at 8:30 am, so he had to be at the airport about 7:30 in the morning. He ordered a mini-cab for 6:30, set his alarm for 5:45, and went to sleep. Unfortunately he forgot to wind the clock, and it stopped shortly after midnight. Also the driver of the mini-cab had to work very late that night and overslept.James woke with that awful feeling that something was wrong. He looked at his alarm clock. It stood there silently, with the hands pointing to 12:10. He turned on the radio and discovered that it was, in fact, ten to nine. He swore quietly and switched on the electric kettle.He was just pouring the boiling water into the teapot when the nine o’clock pips sounded on the radio. The announcer began to read the news, “... reports are coming in of a crash near Heathrow Airport. A Boeing 707 bound for New York crashed shortly after taking off this morning. Flight number 2234...” James turned pale.“My flight,” he said out loud. “If I hadn’t overslept, I’d have been on that plane”.Task 6【答案】A.1) 1964, the United States2) safety belts3) 404) about 155) 24B.1) They do not smoke while driving.2) They have had more education than non-users.3) They know someone who was injured (but not killed) in an automobile accident.C.the importance of using seat belts in driving【原文】According to the American Automobile Association, since 1964 all cars sold in the United States have been equipped with seat belts. (These are also called safety belts.) Many studies of automobile accidents have shown that safety belts can save lives. One study showed that 40 percent of those killed in auto accidents could have been saved if they had been wearing seat belts.Unfortunately belts are worn only by a small percentage of drivers and passengers — about 15 percent in cities, and only 9 percent in small towns. And safety belts cannot protect people who do not wear them.In order to find out what kinds of people do wear seat belts a study was made in seven cities in the United States. The following facts were learned about those who use their safety belt:1. They do not smoke while driving.2. They have had more education than non-users.3. They know someone who was injured (but not killed) in an automobile accident.Advertisements based on these facts have been printed in newspapers and magazines in order to teach people the importance of using seat belts. But these advertisements have not helped much. Some people believe there should be a law requiring drivers and passengers to use safety belts. In Australia, where there is such a law, deaths in auto accidents have decreased 24 percent.Task 7【答案】A.1) Miss Brown.2) Mr. Phillips was Miss Brown’s boss.3) He sounded very angry.4) He had been in a traffic jam for more than an hour.B.1) congested2) alternative routes3) South Circular Road4) broken down5) blown down, in useC.1)T, 2)F, 3)F, 4)F, 5)TD.1) He left home at the usual time and decided to use a new route.2) The traffic lights were out of order because of the storms last night.3) After that there was a breakdown.4) He ran out of petrol.5) He was in traffic jams for three hours.【原文】PartⅠ(Telephone ringing constantly. Sound of key turning in lock, door opening.)Miss Brown: (answering telephone) Good morning. Blue Star Travel Agency. Can I help you? Mr. Phillips: Is that you, Miss Brown? I’ve been ringing the office for 10 minutes. Where have you been?Miss Brown: Sorry, Mr. Phillips. I’ve just arrived. The traffic was terrible this morning.Mr. Phillips: The traffic is still terrible. I’ve been in a traffic jam for more than an hour. Look after the office until I get there. It may take a long time.Miss Brown: certainly, Mr. Phillips. Good luck.(Sound of hanging up.)(to herself) Thank goodness the boss is late too! The first thing I’m going to do istake my coat off. Then I’m going to sit down and have a cup of coffee. I think I’llswitch the radio on too.PartⅡ(Radio being switched on.)Radio: Here is a message for all motorists. Most major roads leading in and out of London are congested. Motorists should use alternative routes wherever possible. The time isnow 9:30. Here is the local traffic news.Announcer: Heavy rain during the night has flooded parts of the South Circular Road. An articulated lorry has broken down on the M1. Traffic is now only 2 lane and movingvery slowly. Strong winds during the night have blown down a number of trees on theM6 and many sections are not in use. That is the end of the local traffic news. Formore news listen again at 10 o’clock.(Sound of radio being switched off and door opening.)Betty: (breathless) Hello, Carol. Sorry, bu t I couldn’t get here earlier.Miss Brown: Never mind, Betty. Have a cup of coffee and relax.Part III(Door open and slammed. Background of typing.)Miss Brown: Oh, it’s you Mr. Phillips. We’ve been worried about you. Are you all right?

Why is he in such a bad mood?Miss Brown: Let’s make a cup of coffee for him and find out. If you make the coffee, I’ll sp eak to Mr. Phillips.(Polite knock at door, door opening.)Miss Brown: We’re making some coffee Mr. Phillips. Would you like to have it with us? You could tell us about your awful journey.(Background sound of cups.)Miss White: Was the traffic bad, Mr. Phillips?Mr. Phillips: Was the traffic bad? We were in traffic jams for three hours. I left home at the usual time and decided to use a new route. For the first time, I used the M4. Never again.That was because of the storms last night. Then the traffic lights were out of order.After that there was a breakdown and.., finally, I ran out of petrol.(Giggles from Miss W. and Miss B. Footsteps. Door slams.)Task 8【答案】1) b, 2) a, 3) cB.a) It was chosen because the cost of energy is not so great as with a bus system.b) It was chosen because it is much easier to carry a greater number of passengers by train than by bus or car.c) It was chosen because the noise and pollution are not so great as with buses and cars.C.1) 12.5, above and below2) Germany, Canada3) Calgary4) 245) only one man6) separate7) 30 seconds8) open the doors themselves.9) automatic ticket machines (placed) on the platforms, zipcards10) get a $25 fine【原文】Calgary is an oil town. It is home for more than half a million Canadians, and this population may well be much closer to three quarters of a million or more by the end of the century. Downtown Calgary is famous: the tall office buildings in the center of the city were in the “Superman” mov ies. But Calgary is also the home of a very modern transport system, and the Light Rail Transit (LRT) is part of it.The rail system was chosen because the cost of energy is not so great as with a bus system, because it is much easier to carry a greater number of passengers by train than by bus or car, and because the noise and pollution is not so great as with buses and cars.But what is the LRT? It is a 12.5-kilometre route, above and below ground. The light train cars are made in Germany and Canada. In Germany they are made by Siemens in Dusseldorf, and then taken to Canada where final assembly is done in Calgary. Each car is just over 24 metres long, and each train is operated by only one man — the driver. The driver is in a separate cabin, and he can’t talk to passengers.The trains stop for about 30 seconds at each station, and passengers who want to get in or out must open the doors themselves.Automatic ticket machines are placed on the platforms. Passengers can buy a ticket from these, or they can buy special monthly tickets called zipcards. However, if passengers are caught without a ticket they may get a $25 fine.Task 9【答案】A.1) deaths and people injured2) drivers, pedestrians, and road conditions3) may cause drivers and pedestrians endanger lives through no fault of their own4) too many road signs, faulty traffic lights, sudden narrowing of a street, and congested parkinga) drive too fast and without any consideration for othersb) think they are safe at the wheel even though they have drunk too much alcoholc) out of some curious sense of power, are incapable of understanding that their car is a lethalweapon if improperly used6)a) step off the pavement without first looking to the left or rightb) cross roads when the traffic lights are against themc) jump off a moving busB.Pedestrians, drivers and road conditions are all to blame for road accidents.【原文】There are far too many road accidents in this country: too many deaths and too many people injured. One wonders who are most to blame: drivers or pedestrians. Some people say that the blame cannot be put fairly without considering the state of the roads and the whole transport system. In crowded cities like London, Birmingham or Manchester, road conditions are so chaotic that both driver and pedestrian often endanger lives through no fault of their own. Such deficiencies as too many road signs, faulty traffic lights, sudden narrowing of a street, congested parking are all a sure indication of bad road conditions.On the other hand, many experts are convinced that the larger part of the blame for the death toll must be put on persons and persons alone: drivers who drive too fast and without any consideration for others, drivers who think they are safe at the wheel even though they have drunk too much alcohol, drivers who, out of some curious sense of power, are incapable of understanding that their car is a lethal weapon if improperly used. Pedestrians, likewise, must share the guilt: stepping off the pavement without first looking to the left or right, crossing roads when the traffic lights are against them, jumping off a moving bus. To be fair, pedestrians, drivers and road conditions are all to blame.One looks forward to the day when the motor car has been replaced by some less dangerous means of transport.Task 10【答案】A.1) 11, 2) Over 400, 3) Over 4,000, 4) $ 400, 5) 60 daysB.1) Most people are going to die from accidents caused by drunk drivers.2) Joe’s sister is worried because it’s getting late and he is drunk.3) The green Ford that Joe is driving is weaving from left to right.4) When Officer Williams asks Joe to walk along the white line, he can’t do it. Joe also fails the breath test.5) He’s going to appear in court next week. He is going to receive a $400 fine. The judge is also going to suspend his license for sixty days.C.enjoying, family party, leave, stay, wait, drives, fine, slowly, had, drinks【原文】It’s a holiday weekend. The police officers were sitting in a hot room receiving instructions from their captain. One of these officers was Ed Williams. He and ten other officers were on special duty. This weekend alone, over 400 people are going to die from accidents caused by drunk drivers. Over 4,000 people are going to receive serious injuries, all caused by drunk drivers. The officers are going to try to prevent these accidents before they happen.Meanwhile, Joe Forest is enjoying himself at a family party. It’s getting late and he’s telling his sister that he’s going to leave. She’s asking him to stay and wait a few hours before he drives. “Don’t worry. I’m going to be fine. I’m going to drive slowly. I only had a few drinks.”Officer Williams is at a toll booth, watching cars enter the area. A green Ford is approaching, weaving from left to right. Officer Williams stops the car and tells Joe to get out. He asks Joe to walk along the white line. Joe can’t do it. Joe also fails the breath test. Officer Williams is telling Joe that he’s going to issue him a summons. And he can’t drive his car home. Joe calls his sister. She’s going to come and drive him home.This was Joe’s first offense. He’s going to appear in court next week. He is going to receive a $400 fine. The judge is also going to suspend his license for 60 days. This first time, other drivers were lucky. Joe didn’t kill them. But what about the future, is Joe going to stop drinking and driving?Task 11【答案】If you are a daily Transit rider, carry a zipcard. It’s quick, convenient and gives you unlimited rides on any regular Calgary Transit service. The zipcard saves you money too! Pay the adult fare of 90c, twice a day for 22 working days each month, adds up to $39.60. But a zipcard costs just $31 a month. It also saves you the extra 10c on all express buses. Buy a zipcard and take advantage of the best way to ride.。

Maria: No, I don’t think so. But I have noticed a few differences.Margaret: Oh, such as what?Maria: Well, the family unit seems to be smaller here than in my country. For you, the family is simply Mum, Dad and the children.Margaret: Y ou have a more extended family circle, do you?Maria: Y es. It’s quite common in my country to have a grandmothe r and an unmarried aunt or uncle living in as part of the family. And we wouldn’t dream of sending anelderly relative to an old people’s home, for instance.Margaret: Y ou take care of elderly relatives yourselves, I guess.Maria: Oh yes. We haven’t got all your welfare services and it’s the family’s duty to loo k after an elderly parent, for example.Margaret: What about hospitality? Do you think English families do a lot of entertaining? Maria: Y es, but in a rather f ormal way. Y ou don’t like people to “drop in” without a previous invitation, do you? In my country it’s quite usual to drop in on friends andrelatives.Margaret: Have you ever lived in with an English family?Maria: Y es, I have. I was an au pair girl for a year. I learned a lot about English family life then. I’d never realized how fond the Englishman is of his home and family, his gardenand his pets.Margaret: Pets? What sort of pets did they have?Maria: Oh, all sorts— dogs, cats and goldfish.Margaret: Did you enjoy living in with the family?Maria: Oh, yes. They were very kind.

I think families used to be much larger. My grandmother was one of fourteen children! V ery few people nowadays care to have such large families. Susan: I suppose that’s why in those days very few women took up careers outside the home. They were too busy bringing up their families.Marilyn: Y es, but most well-to-do families had servants to do the housework and even nannies to look after the children.Susan: Would you like to have lived then, Marilyn?Marilyn: Not particularly! Women weren’t as free as they are today. They often had to marry men they didn’t like and they were financially dependent on their parents ortheir husbands. I think we’re much better off today, don’t you?Susan: Well, I suppose we have more freedom of choice and we’re more independent, but, you know, some arranged marriages were very successful. And there wassomething rather charming about courtship in those days.Marilyn: Really? Such as what?Susan: Well, the custom of asking a girl’s father for permission to marry her, for example. Marilyn: An d supposing he didn’t give his permission? No, thank you. I think family life is much pleasanter today because it’s freer and more informal. At least today we’re free tomarry whoever we like and to take up a job, if we wish.Susan: That’s true. But I still think that family life in the old days must have been very pleasant and secure.T ask 6【答案】1) They never interfered with her plans too much and she was allowed to take up the career she wanted.2) She became independent financially.

My parents never interfered with my plans too much. They advised me but never forced me to do anything I didn’t want to do. I was allowed to take up the career I wanted. I think I respect and love them more for this.Bella: Are you quite independent of them now?Joyce: Y es. As soon as I left school and started my studies as a nurse, I became independent financially. I have a government grant which is enough for my keep. But I still stay with them a lot, as you know.Bella: Y ou seem very close to your parents.Joyce: I am. I know that many young people today say they have nothing in common with their parents, but I’m rather lucky because I get on well with mine. What about you,Bella?Bella: Well, we value fam ily life very much in my country. I’m very fond of my family, but I don’t always get on very well with them. They try to control me too much.Joyce: But they allowed you to come to study in England on your own!Bella: Y es, but only after a lot of persuasion!

Y ou live in Brighton, was it? Well, Brighton’s ....Rosemary: No. Manchester... I live in Manchester.Tessa: Oh. I’m sorry, love. I’m getting mixed up.

And Christine’s ho use is in a very quiet part.Tessa: Christine. That’s your friend, is it?Rosemary: Yeah. That’s right. I mean, I know my dad gets worried but it’s perfectly safe. Radio Presenter: Rosemary, have you talked about this with your dad?Rosemary: No. He just s houts and then he says he won’t let me go out at all if I can’t come home on time.Radio Presenter: Why don’t you just try to sit down quietly with your dad—sometime when he’s relaxed—and just have a quiet chat about it? He’ll probably explain why hew orries about you. It isn’t always safe for young girls to go out at night.Tessa: Y es. And maybe you can persuade him to come and pick you up from Christine’s house once or twice.Rosemary: Yes. But I don’t think he’ll agree to that. Anyway,I’ll talk to him about it.

These days, a household may consist of one person, several generations under the same roof, or a double-income-no-kids (DINK) family.A national survey by Horizon Research Group released over the weekend shows that families in China’s cities are becoming more and more diverse.The most common family type in Chinese cities was once the nuclear family. But while it accounted for 48 percent of families in urban areas in 1997, that figure has decreased to 37 percent today, the survey shows.Covering more than 1,000 households in Beijing, Shanghai, Guangzhou and Wuhan, the survey found that the number of DINKs, one-person and linear or generational families is on the rise from six years ago.The research group carried out a similar survey of family types in 1997, covering more than 5,100 households in 10 major cities across China.This time round, more than 7.2 percent of respondents classified themselves as DINKs, 1 percentage point higher than six years ago.One-person households account for 6.8 percent of respondents, 3.9 percentage points higher than the previous survey.Linear families—a married couple living with their parents or three generations living together — increased in number by 6.4 percentage points, reaching 49 percent.According to social science experts, it seems certain more distinct lifestyles will emerge, for example, cohabitation and celibacy are both on the rise.In any event, today’s pluralistic society, with its diverse values, should be welcomed, said Li Yinhe, a sociologi st on family and marriage. “Everyone’s choice, whether traditional or unconventional, should be respected,” Li said.Since the DI NK lifestyle emerged in the 1980s, it has sprung up in all of China’s big cities. Beijing now has 10,000 DINK families. When combined with those in Shanghai and Guangzhou, the figures rise to about 60,000, according to Y outh League Committee of Beijing statistics.Childbearing was in ancient China a family’s top priority, but now it is regarded as a personal choice by many young couples.Zheng Jian, a 38-year-old businessman, and his wife Xiao Y an, a graphic designer, think their two-person family is one of the happiest in the world.They have been married for more than 10 years and have no children.“We always have so many plans together, to do things together,” said Zheng. “And it seems like we are two kids who like playing together.”They insist: “We are satisfied with our present lives, so why bother with children?”T ask 13【答案】In the past, when more Americans lived on farms, the typical family had many children. In a farm family, parents and their children often lived with grandparents. Often, too, uncles and auntslived nearby. But when industry became more important than agriculture in American life, families became smaller. Industry requires workers who are ready and able to move off the land and to move again whenever necessary. Large families cannot be moved from place to place as smaller families can.Today, because of industrialization, a typical family will be required to move even more often, so families will be even smaller. The typical family may remain childless and consist only of a man and a woman. A smaller number of families may raise children. These families may raise children as their chief occupation, leaving the childless families free to move from job. Furthermore, these child-raising families may raise other people’s children in addition to their own.。

At last they got so wild with hunger that one of the boys, who was tall for his age, said:"If this goes on, I am afraid I shall eat the boy who sleeps next me." He had wild hungry eyes and the boys believed him. The boys gathered and thought of a plan."One of us must walk up to the master at supper this evening and ask for more gruel," said one boy."Let us east lots," said another. "In that way we shall see who must go up to the master and ask for more."So they cast lots. The lot fell to Oliver Twist. He had to go up to the master and ask for moregruel.The evening came. The boys took their places and quickly ate up their gruel. Then they looked at Oliver. He rose from his place, bowl and spoon in hand, went up to the master and said, "Please, sir, I want some more." The master was a fat, healthy man, but he turned pale."What!" he said at last.Oliver repeated: "Please, sir, I want some more."The master struck Oliver on the head and pushed him out of the room.For a week Oliver remained a prisoner in the cellar.Task 2【答案】A. 1) F 2) F 3) TB.1) d 2) b【原文】Mark Twain was a famous American writer. There were many stories about him. One day Mark Twain was fishing. A stranger came along. "Good morning!" said the stranger."Good morning!" said Mark Twain. "Nice weather we're having!" "Very nice indeed," said the stranger. "How was fishing""Very good. I caught three trout here yesterday in just about an hour.""Is that so" said the stranger."Yes. I'm very fond of trout.""By the way," said the stranger, "do you happen to know who I am""No, I haven't any idea," said Mark Twain."Well, I'm the game warden of this county," said the stranger. "Fishing is not allowed here."Mark Twain paused a minute. Then he asked:"By the way, do you know who I am""No, I don't.""Well, I am the biggest liar in the country."Task 3【答案】A.Name: Lewis CarrollOccupation: mathematics; Oxford UniversityLiterary works: Alice’s Adventures in Wonderland; 1865;Through the Looking-Glass; 1871B.These stories are about a dream world in which Alice meets strange creatures and has interesting adventures.【原文】Which would you rather be A mathematician or a writer Perhaps you will never be faced with this kind of choice. Lewis Carroll was both a mathematician and a writer. He was a lecturer in?mathematics at Oxford University. But he is better known as the author of two of the most famous children’ s books that have ever been written: Alice’s Adventures in Wonderland and Through the Looking-Glass. The author’s real name was Charles Lutwidge Dodgson, but he preferred to use the pen-name “Lewis Carroll”when he wrote Alice’s Adventures in Wonderland and this is the name we remember him by.Alice’s Adventures in Wonderland was published in 1865, whenits author was 33 years old; it was followed by Through the Looking-Glass in 1871. Both books were written for a real girl called Alice, but they have been read by millions of children since they were first published. These stories are about a dream world in which Alice meets strange creatures and has interesting adventures . I’m sure you know this already, but if you don’t, you had better read the stories yourselves.Task 4【答案】the Greeks, closed the gates of the city and stayed behind the walls, the Greeks, a huge wooden horse, hide inside it, the horse, they stopped, hid their ships, Greek prisoner, the horse, The Greek soldiers, the wooden horse【原文】Many, many years ago there was a war between the Greeks and the Trojans. The Greek ships sailed up to the city of Troy. When the Trojans saw the Greek ships, they closed the gates of their city and stayed behind the walls. The Greeks attacked the city many times, but could not take it. Then one of the Greeks thought of a plan. The Greeks made a big wooden horse and had some soldiers hide inside the horse. In the morning the Greeks burned their camps and sailed away. Only the big wooden horse remained in front of the city gate.But the Greek ships did not sail far. The Greeks stopped at a place near Troy, where the Trojans could not see them, and hid their ships. At first the Trojans wanted to burn the wooden horse, but a Greek prisoner said, "Don't bum the horse. Bring it into Troy. It will help you."The horse was very big, and the Trojans could not bring it in through the gate. They had to make a hole in the wall. Then they brought the wooden horse into the city. The next day was a holiday in Troy. At night all the Trojan soldiers fell asleep after a heavy festive drinking.The Greek ships came back to Troy in the night. When everything was quiet, the Greek soldiers came out of the wooden horse and opened the gates of the city. The Greek army came into the city, killed many Trojans and took the city.Task 5【答案】A.1) c 2) aB.1) All the animals thought that he was the king of beasts. Actually he was a coward. He was afraid of human beings and other big animals. He roared only to scare them away and never really hurt them.2) Dorothy and her dog wanted to get back to Kansas. The Scarecrow wanted some brains and the Tinman wanted a heart. The Lion wanted to have courage.【原文】The following story has been taken from The Wonderful Wizard of Oz written by L. Frank Baum in 1900. The book is a modern fairy tale and is one of the great favorites of American children.One day a tornado carried away Dorothy and her dog Toto from their home in Kansa sand landed them in the wonderful land of Oz. Here they made friends with two strange fellows, a scarecrow and a tin man. The four were now on their way to the Emerald City where the Great Oz lived.Just as the Tinman spoke there came from the forest a terrible roar, and the next moment a great Lion rushed into the road. With one blow of his paw he knocked the Scarecrow to the edge of the road, and then he hit the Tinman with his sharp claws. But, to the Lion's surprise, he could make no mark on the tin, though the Tinman fell over in the road and lay still.Little Toto, now that he had an enemy to face, ran barking towards the Lion. The great beast had opened his mouth to bite the dog. Dorothy feared that Toto would be killed. She forgot all danger and rushed forward. She slapped the Lion upon his nose as hard asshe could, and cried out:"Don't bite Toto! You should be ashamed of yourself, a big beast like you, to bite a poor little dog!""I didn't bite him," said the Lion, as he rubbed his nose with his paw where Dorothy had hit it."No, but you tried to," she said in anger. "You are nothing but a big coward.""I know," said the Lion, and he hung his head in shame. "I've always known it. But how can I help it""I don't know, I'm sure. But how can you hit a stuffed man like the poor Scarecrow""Is he stuffed" asked the Lion, in surprise, as he watched her pick up the Scarecrow and set him upon his feet, while she patted him into shape again."Of course he's stuffed," replied Dorothy. She was still angry. "That explains it. He really went over easily," said the Lion. "It surprised me to see him turn around so. Is the other one stuffed also""No," said Dorothy, "he's made of tin." And she helped the Tinman up again."He really hurt my claws," said the Lion. "When they scratched against the tin it made a cold shiver min down my back. What is thatlittle animal you are so kind to""He is my dog, Toto," answered Dorothy."Is he made of tin, or stuffed" asked the Lion. "Neither. He's a meat dog," said the girl."Oh. He's a curious animal, and seems really small, now that I look at him. No one thinks of biting such a small, little thing except a coward like me," continued the Lion sadly."What makes you a coward" asked Dorothy. She looked at the great beast in wonder, for he was as big as a small horse."I don't know," replied the Lion. "I suppose I was born that way. All the other animals in the forest expect me to be brave, for the Lion is everywhere thought to be the King of Beasts. I learned that if I roared very loudly every living thing was afraid and got out of my way. Whenever I've met a man I've been very much frightened; but I just roared at him, and he has always min away as fast as he could go. If the elephants, tigers and bears ever tried to fight me, I would run away — I'm such a coward; but just as soon as they hear me roar, they all try to get away from me, and of course I let them go.""But that isn't right. The King of Beasts shouldn't be a coward," said the Scarecrow."I know it," said the Lion, and he wiped a tear from his eyewith the tip of his tail. "It is a great sorrow, and it makes my life very unhappy. But whenever there is danger, my heart begins tobeat fast.""Perhaps you have heart disease," said the Tinman."It may be so," said the Lion."If you have," continued the Tinman, "you should be glad, for it proves you have a heart. For my part, I have no heart; so I can't have heart disease.""Perhaps," said the Lion, "I am a coward because I have a heart." "Have you brains" said the Scarecrow."I suppose so. I've never looked to see," replied the Lion. "I am going to the great Oz to ask him to give me some," remarked the Scarecrow, "for my head is stuffed with straw.""And I am going to ask him to give me a heart," said the Tinman. "And I am going to ask him to send me and Toto back to Kansas," added Dorothy."Do you think Oz can give me courage" asked the Cowardly Lion. "Just as easily as he can give me brains," said the Scarecrow. "Or give me a heart," said the Tinman."Or send me back to Kansas," said Dorothy."Then if you don't mind, I'll go with you," said the Lion, "forlife is hard without courage.""You will be very welcome," answered Dorothy, "for you will help to keep away the other wild beasts. I think they must be more cowardly than you if they allow you to scare them so easily.""They really are," said the Lion, "but that doesn't make me any braver, and as long as I know myself to be a coward I shall be unhappy."So once more the little company set off upon the journey. The Lion walked at Dorothy's side. Toto did not like the Lion at first, because he could not forget how nearly he had been crushed between the Lion's great jaws; but after a time he became more at ease, and before long Toro and the Cowardly Lion became good friends.Task 6【答案】A.1) Civil War2) first, equality3) battlefields, bloodiest4) ordinaryB.1) d 2) c【原文】Walt Whitman is often called the poet of American democracy. He lived during the American Civil War, and he admired President Abraham Lincoln very much.Whitman was the first American poet who wrote about tree equality among all people. In a poem called "Song of Myself" he compared himself to all other people, and he found no difference. He wrote:"...every atom belonging to me... belongs to you."In the same poem Whitman spoke up for women. He wrote:"The Female equally with the Male I sing."He also wrote:"In the faces of men and women I see God." and "A great city is that which has the greatest men and women."Whitman understood war and the results of war. He worked in a hospital, taking care of wounded men. In a description of northern soldiers who had returned from prisons in the south he wrote: "The sight is worse than any sight of battlefields or any collection of wounded, even the bloodiest." In Whitman's words: "The real war will never get in the books."Whitman was the first important American poet to write about ordinary people, using ordinary language.Task 7【答案】A.1) A red, red rose that’s newly spring in June and the melody that’s sweetly played in tune.2) He will love her till all the seas are dried and the rocks melt in the sun. his love will last as long as the sands of life run(there is life on earth).3) Yes, he is, and he will come back no matter how far it is.B.June---tune I---dry sun---run while ---mile【原文】O, my love is like a red, red rose,That is newly sprung in June.O, my love is like the melody,That is sweetly played in tune.As fair are you, my lovely lass,So deep in love am I,And I will love you still, my Dear,Till all the seas go dry.Till all the seas go dry, my Dear,And the rocks melt with the sun!O I will love you still, my Dear,While the sands of life shall run.And fare you well, my only Love,And fare you well a while!And I will come again, my Love,Although it were ten thousand mile!Task 8【答案】1) Tall stories, that is, unlikely ones.2) Because he wanted to be a member of a certain club.3) He went there because he was told that a lion came there each evening to drink water.4) Sixteen times.5) He killed sixteen lions.【原文】A famous French writer who wrote many books about England and the English people once wrote about the Englishman's fondness for improbable or tall stories. In one of his books about the First World War, an English priest tells the following story:He had wanted to become a member of a certain club in Africa. In order to become a member, each person had to shoot at least onelion. The priest had never shot an animal in his life. So, armed with a rifle and accompanied by a young African boy, the priest set out one evening for a pool in the jungle where he was told a lion came each evening to drink. He waited patiently for a few hours until shortly before midnight when he heard a rustling noise. Sure enough a few yards away the head of a lion appeared above a bush that separated the priest and the pool. He aimed and fired. The head of the lion immediately fell behind the bush but a moment later reappeared. So the priest aimed and fired again. The head of the lion immediately fell behind the bush but a moment later reappeared. The priest fired again: the same result. He remained calm because he knew he had brought sixteen bullets with him. After his fourth attempt his aim seemed to become more and more inaccurate. In fact, after his fifteenth attempt the African boy had to warn him, "This is your last chance. If you miss this time, we are in trouble." The priest then realized how serious the situation was, so he took a deep breath, aimed very carefully and fired. They waited a moment, then slowly counted up to twenty: the head of the lion did not reappear. The priest was certain that at last he had shot his lion. They rushed forward together to the spot behind the bush. And what do you think they found Sixteen lions.Task 9【答案】I. a young prince who lived on landA. rose to the surface of the sea and waited for the prince to come to herB. never cameII. a witchA. changed her fish’s tail into a pair of human legsB. she gave the witch her tongueIII. the prince’s palaceA. her feet hurt terriblyB. didn’t love herⅣ. a young princessA. drive back into the seaB. a spirit of the air and lived forever【原文】Copenhagen is the capital of Denmark. In Copenhagen harbor, you can see a statue of the Little Mermaid. I wonder if you know her story. It's a sad one.That Little Mermaid fell in love with a young prince who lived on the land. Every night she used to rise up to the surface of the sea and sit staring at his palace, waiting for him to come to her. But he never came.Finally she visited a witch. The witch changed her fish's tail into a pair of human legs so that she could go and live on land. But in return, the Little Mermaid had to give her tongue to the witch, so that she could never sing or speak again. She loved the prince so much that she gave it happily.She went and lived in the prince's palace, and every night, she danced for him, although her strange new feet caused her terrible pain. But she didn't mind the pain. She waited and waited for the prince to fall in love with her.But, although the prince liked the Little Mermaid very much, he didn't love her. He fell in love with a young princess and they got married. On their wedding night, the Little Mermaid sadly dived back into the sea. She had no tail now, only legs, and she thought that she would die. She didn't die, though. Because of her kind heart, she became a spirit of the air and lived forever.Task 10【答案】A.1) b 2) c 3) b 4) a 5) aB.No. 1[e] No. 2 [b] No. 3 [a] [d] [c]【原文】1) A wolf thought that by disguising himself as a sheep he could get enough to eat. So he put on a sheepskin and joined the flock without being discovered. At sunset the shepherd shut him with the sheep in the fold. Then he felt hungry, so he picked up his knife and killed one of the sheep for his supper. But it was the wolf that he killed.2) A bird in a cage at a window used to sing during the night.A bat which heard her came up and asked why she never sang by day, but only by night. She explained that there was a good reason: she was caught while she was singing in the daytime, and this had taught her a lesson. "One must be careful before one is caught, not after," said the bat.3) Monkeys are said to have a strange habit. When twins are born to them, the mother will take care of only one of the twins. She will hold it tightly to her breast and neglect the other. But the one taken care of will die because it cannot breathe freely, while the neglected one will grow up strong and healthy.4) A gnat alighted on a bull's horn. After it had stayed therea long time and felt like moving on, it asked the bull if he would like it to go now. "I didn't notice when you came," replied the bull, "and I shall not notice if you go."5) A reed and an olive tree were quarrelling one day. Theywanted to see which one was the stronger. Finally the olive tree said to the reed, "You are weak. You are easily bent by the wind." But the reed did not say a word. Before long a storm arose. The reed was tossed about and bent by the winds, but it was not hurt. The olive tree stood bravely against the storm and was broken by its force.Task 11【答案】I.A. struck a rock and began to break up.B. sank tooC. had survivedII.A. he was tied very firmly by a large number of fine ropes.B. about forty little men shot at him with their arrows, which hurt like needles.C. the little men gave him all the bread, meat and wine they had. III.was seven feet by three feet, equipped with twenty-two wheels and pulled by fifteen hundred little horses【原文】Gulliver was travelling by ship. The ship struck a rock and beganto break up. Some of the sailors and Gulliver got away in a boat, but that sank too. In the end Gulliver was the only person who survived-who didn't drown. He kept on swimming, and just managed to reach land. By that time it was already evening. Gulliver kept on walking, but by then he was so exhausted that he lay down on the grass, and fell sound asleep.He slept until the following morning. When he woke up, he could not move. His arms and legs were tied to the ground, very firmly, and so was his hair. There were a large number of very fine, thin ropes across his body, he discovered, and these prevented him from moving.Gulliver could just manage to look down his body — that was all he could do — and there he saw, advancing up his body, about forty little men. These little men were only about six inches high. They were dressed as soldiers, and each one carried a bow and arrow. Gulliver shouted out, and when he did this, all the soldiers ran away, though they gradually came back again.Gulliver decided to try to escape. He managed to break some of the ropes, and he was also able to free his head. But when he began to move, the soldiers shot at him with their arrows. These arrows were small but sharp like needles, and they hurt Gulliver. He decided to keep still and when he did so, the soldiers stoppedshooting at him with their arrows.By this time Gulliver was feeling very hungry, so he put his finger to his mouth, to show the little people that he needed food. They understood this, and they brought him bread and meat. Gulliver ate all the bread and meat, and then indicated that he was thirsty. Again he was understood, and the people brought him wine. In fact Gulliver drank all the wine that was available — all they had. After that one of the king's officers came up to Gulliver. He spoke to him, and indicated that he had to go to the city, to the capital of the island. This was what the king had ordered. Guliver asked to be set free, but the officer refused. Gulliver again thought of trying to escape, but he remembered those arrows which the soldiers had shot at him, and he decided to do nothing. In any case he soon fell asleep, because of all the wine he had drunk.While he was asleep, the people on the island made arrangements — got everything ready — to take Gulliver to the capital. They managed to get him on a cart which they had built specially to take him to the city. It was seven feet long, and three feet wide, and it had twenty-two wheels in all. It took about three hours to get Gulliver on the cart, and fifteen hundred horses to pull the cart to the city.Task 12Aesop was a very clever man who lived in Greece thousands of years ago. He wrote many good fables. He was known to be fond of jokes. One day, as he was enjoying a walk he met a traveler, who greeted him and said, “Kind man, can you tell me how soon I shall get to town”“Go,” Aesop answered.“I know I must go”, said the traveler, “but I should Like you to tell me how soon I shall get to town.”“Go,” Aesop said again angrily.“This man must be mad,” the traveler thought and went on.After he had gone some distance, Aesop shouted after him, “You will get to town in two hours.” The traveler turned around in astonishment. “Why didn’t you tell me that before” he asked.“How could I have told you before”answered Aesop. “I did not know how fast you could walk.。
《现代大学英语听力2》听力原文及题目答案Unit 2Unit 2Task 1【答案】1) b 2) a 3) d【原文】Texas was the biggest state before Alaska became the forty-ninth state in 1959. One good way to understand the size of Texas is to learn about its weather. Different parts of the state have very different kinds of weather.Laredo is one of the hottest cities in the United States in summer. The best time to visit Laredo is in winter, when it is pleasantly warm.Amarillo gets very cold in winter. Sometimes there is more snow in Amarillo than in New York, which is a northern city. Summers are better, but sometimes it gets quite hot. The best time to visit Amarillo is in the autumn when it is cool.If anyone asks you about the weather in Texas, ask him, “What part of Texas do you mean”Task 2【答案】A.1)T 2) F 3) FB.1) d 2) c 3) cC.climate, reputation, extraordinary, unreliable, dry, wet, clear, dull, hot, cold, bad, mild【原文】Our friend, Nick, whose English gets better and better, declared solemnly the other day that he thought that the British climate was wonderful, but the British weather was terrible. He went on to explain by pointing out that the British climate was a temperate one. This meant, he said, "that you could always be certain that the weather would never be extreme — at any rate not for any length of time — never very hot and never very cold." He quite rightly pointed out that the rainfall in Britain, according to the statistics, was not very heavy. "Why then," he asked, "has the British climate such a bad reputation" He answered by saying it was because of the extraordinary, unreliable weather. There was no part of the year at which you could be certain that the weather would be dry or wet, clear or dull, hot or cold. A bad day in July could be as cold as a mild day in January. Indeed you could feel cold at almost any time of the year. Nick blamed drafty British houses for this, but agreed you could also blame the small amount of sunshine and a great amount of dampness. He advised every student coming to Britain to bring an umbrella and to understand the meaning of that splendid word "drizzle".Task 3【答案】I.the country; Trees, grass, lakes and steamsII.A.1. concrete, iron, steel2. take in the heat during the day and throw off heat into the air at nightB. Warmer winters, car engines; electrical applianceⅢ.A. air pollution may stop sunlight from reaching the earthB.1. Ice near the North and South poles to melt2. to be slowly flooded and people living in these cities to move to higher land【原文】Cities change the climate around you. In the country, there are trees, grass, lakes, and streams. In hot weather, the trees and grass cool the area around them. Lakes and rivers also cool the area around them.But cities are not cooled in these natural ways. Cities are built of asphalt, concrete, iron, and steel. There are few trees and usually not much grass. Rain falls onto the streets and into the sewers.When the summer sun shines, streets and buildings take in the heat; after the sun sets, the streets and buildings throw off heat into the street. Once the sun sets, the countryside cools off, but a city may stay hot all night.Cities are hotter than the countryside in winter, too. Standing near a car with its motor running, winter or summer, you will feel the heat thrown off by the engine. The heat comes from the gasoline burned by the engine. This heat warms the air and the ground around the car. Thousands of running cars are almost like thousands of small fires burning.Carefully put your hand near a light bulb or television set. As you can see, electricity creates a lot of heat. This heat from electricity warms the house and the outside air.The heat given off by cities can affect the climate. Some experts even believe that cities can change the climate of the whole world. They think that air pollution may stop sunlight from reaching the earth. If less sunshine reaches the earth, the earth may become cooler.Still other experts think the world will get warmer. If the world did get warmer, great changes would occur. Ice near the North and South poles would melt. This would make the oceans rise. Cities near oceans — like Los Angeles, Boston, and Miami — would slowly be flooded. People living in these cities would have to move to higher land.Task 4【答案】A.1) b 2) cB. night, delight; morning, warning; gray, way, red, headC.1) F 2) T 3) F【原文】A red sky at either dusk or dawn is one of the spectacular and beautiful weather predictors we have in nature. By closely observing this phenomenon, you can achieve short-range accuracy of the weather as good as, or better than your local weatherman. In the Bible, Jesus in Matthew 16, 2-3 is quoted as saying, “When it is evening, it will be fair weather: for the sky is red. And in the morning it will be foul weather today: for the sky is red” when speaking to the Pharisees. An old English weather proverb based on this passage is:Red sky at night, sailors delight.Red sky at morning, sailors take warning.OrEvening red and morning gray,Sends the traveler on his way.Evening gray, morning red,Brings the rain down on his head.At dusk, a red sky indicates that dry weather is on the way. This is due to the sun shining through dust particles being pushed ahead of a high pressure system bringing in dry air. A red sky in the morning is due to the sun again shining through dust. In this case however, the dust is being pushed on by an approaching low reassure system bringing in moisture. Don't confuse a red sky in the morning with a red sun in the morning. If the sun itself is red and the sky is a normal color, the day will be fair.Task 5【答案】1) c 2) b 3) d 4) c 5) c【原文】Mark: I am an avid fly fisherman and frequently find myself on the river in a raft during lightning storms. We always have a debate at these times on where weare safest — pulling into shore or staying on the water. Since I have heard oneis safe in a car when lightning strikes I wonder if the raft floating on the wateris insulated, and therefore the safest place to be.Meteorologist A: We spoke with some scientists about your question, and they all agreed that under no circumstances should you remain on the water during a lightningstorm. If your raft is made of rubber, you might feel that you're .well insulated,but don't kid yourself. Typical lightning flashes travel 10 to 15 kilometers andcan deliver as much as 100,000 amps of current. In comparison, a toaster usesabout 10 amps of current. If lightning strikes the water near you, it will have notrouble traveling through a few extra centimeters of rubber.Meteorologist B: So, if you're on the water and a thunderstorm approaches, get to the shore and seek shelter on land. Try a building or car. If neither is available, look for a cave,cliff, wall, or a group of trees. Never take shelter under an isolated tree-it's alsoa good target for lightning.Task 6【答案】A.1) F 2) T 3) F 4) T 5) F 6) TB.Incredible, one minute, one kilometer, destroyed, lifted up, carried away, killed, injured【原文】Every spring and summer many inland areas are hit by tornados. A tornado is a kind of storm. It's a revolving, funnel-shaped column of air that moves through the sky at very high speeds. A tornado looks like a huge, black ice cream cone whirling through the sky. The speed of a tornado is very fast-it is believed to be between 200 and 700 kilometers per hour.Tornados form under very special weather conditions, and these special weather conditions occur most often in inland areas, such as the central United States. A tornado forms when a layer of warm, dry air is on top of a layer of cooler, moist air. This combination of dry, warm air above wet, cool air creates a condition that causes the lower layer of air to lift up. As the lower air rises, both layers of air begin to rotate, to turn around and around. The air begins to rotate faster and faster because of centrifugal force. The tornado has a center called an “eye” and the air rotates quickly around this eye.As the air begins to rotate faster and faster, the tornado cloud begins to grow downward; that is, it begins to form a funnel or cone, and this cone goes down toward the ground.The cone of air is dark because it develops from a dark rain cloud. As the cloud gets longer, as the cloud gets closer to the ground, it begins to pull up dirt from the ground. Then the funnel ofrotating air becomes very dark because of the dirt in it. As the tornado funnel gets longer, it begins to drag along the ground.When the tornado touches the ground, it does incredible damage. It usually touches the ground for only about one minute, and it usually travels along the ground for only about one kilometer, but during that one minute, buildings are destroyed, trees are lifted up out of the ground, small objects are carried away, and sometimes people are injured or killed.Task 7【答案】A.1) b 2) a 3) bB.1) It has been nice weather during the day, but it is going to change at night.2) Fine weather in southern Europe and not so nice in northern EuropeFor todaySoutheast England---26 degrees Celsius by mid-afternoonSouthern Scotland---Maximum temperatures of around 21 degreesBrighton---15 hours of lovely sunshineMidlands---23 degrees Celsius by early afternoonNorthwest of Scotland---Light showers around middayFor the weekendSpain---34 degrees CelsiusGreece---32 degrees CelsiusFrance---Cloudy with rain, maximum temperatures of 22 degreesNorthern Ireland---Heavy rain, 17 degrees CelsiusMost of England---Cloudy but mainly dry with sunny periods, 23 degrees Celsius【原文】Radio Announcer: You’re listening to Radio Metro. It’s two minutes to nine, and time for the latest weather for cast from Dan Francis at the London Weather Centre.Francis: Hello. It's been another warm and fine day for most of us. Temperatures in southeast England reached 26 degrees Celsius by mid-afternoon, and Brighton had 15 hours of lovely sunshine. Further north it was a little cooler with maximum temperatures of around 21 degrees in southern Scotland, and in the far northwest of Scotland there were some light showers aroundmidday. But the rest of the country, as I said, has been warm and dry with temperatures in the Midlands reaching 23 degrees Celsius by early afternoon though it was a little cooler along the west coast and in Northern Ireland. But already the weather is beginning to change, I'm afraid, and during the night showers will slowly move in from the Atlantic to reach south-west England and the southern coast of Wales by early morning.The rest of the country will have a very mild, dry night with minimum temperatures no lower than 15 degrees in the south, a little cooler — 11degrees or so — in the north. Any remaining showers in northwest Scotland will pass quickly to leave a mild, dry night there too.And now the outlook for Friday and the weekend. Well, southern Europe will, once again, get the best of the weekend weather, and if your holiday starts this weekend, then southern Spain is the place to go, with temperatures of 34 degrees along the Mediterranean coast. At the eastern end of the Med, too, you can expect uninterrupted sunshine and temperatures of up to 32 degrees Celsius in Greece and southeast Italy, but further north the weather's not so settled. Much of France, Belgium and the Netherlands will be cloudy with occasional rain, and maximum temperatures will be around 22 degrees — very disappointing for this time of the year. Scotland and Northern Ireland will have heavy rain for much of the weekend and temperatures will drop to a cool 17 degrees. Across most of England the weather will be cloudy but mainly dry with sunny periods. And when the sun does come out, temperatures could rise to a maximum of 23 degrees.Task 8【答案】As the air pressure around you either rises or falls, many changes in nature occur. Most of these are very obvious changes while others are of a more subtle nature.Mountains and other far away objects will appear to be much closer and more sharply focused as wet weather approaches and the air pressure drops. The dust particles in the air begin to settle to the ground and the air clears, allowing you to see more details of faraway objects. As a high pressure front approaches and the air becomes “thicker,” more dust particles become suspended in air and things take on their normal somewhat hazy appearance.“Sharp horns on the moon threaten bad weather.” This and a bright, clear moon are goodindicators that wet weather is on the way. As the air clears of dust particles ahead of a low pressure system, the moon appears to come closer and be more sharply focused due to the lack of dust.Sound also becomes sharper and more focused prior to stormy weather. Instead of traveling upward and outward into the atmosphere sound waves are bent back to the earth and their range extended. Bird calls sound sharper, and, at my house, we can hear the blowing of the train horn as it rumbles through the valley below.If you find yourself out in a marsh or swamp and the air really seems to stink more than normal, expect rainy weather. This happens when the pressure drops and the methane trapped on the bottom of the swamp is released in greater quantities. In reverse, as fair weather approaches and the pressure rises, things won't smell quite so strong.Birds and bats have a tendency to fly much lower to the ground right before a rain due to the “thinning” of the air. They prefer to fly where the air is the most dense and they can get greater lift with their wings. With high pressure and dry air, the atmosphere becomes denser and they can easily fly at higher altitudes.Smoke rising straight into the air means fair weather and smoke hanging low means rain is on the way. This is pretty much the same as with the birds and methane in the swamp. When high pressure approaches, smoke will rise whereas with low pressure it can't rise and tends to lay low.Remember a grandparent talking about how their corns, bunions, or joints ached right before a rain Again, this is due to the decreasing atmospheric pressure allowing the gas in our bodies to expand.Task 9【答案】A. Statements 3, 6, 7 are true.B.f—c—a—d—b—eC.1) F 2) T 3) F 4) FD.1) d 2) b【原文】It was 1974. Richard Nixon was still president. Kidnapped heiress Patty Hearst was still missing. In Xenia, a pretty spot of 25,000 people amid fields of soybeans and corn, American Graffiti was held over at the Cinema. The Xenia Hotel offered a chicken and dumpling dinner for $, but everyone flocked to the A&W drive-in for burgers and root beer floats. That's where five of the bodies were found after the storm.In all, 33 people died in Xenia's tornado, the deadliest of 148 storms that raged through 13 states during the infamous "Super Outbreak'' of tornadoes April 3 to 4, 1974. In 16 hours and 10 minutes, 330 people were killed and nearly 5,550 were injured from Illinois to Georgia.Though the Xenia death toll has been matched by other killer storms, the degree of devastation makes the city's tornado among U.S. history's most destructive. The storm still is studied in colleges by aspiring meteorologists, a textbook case of a rare Category F-5, the most intense of tornadoes.On that fateful day, I was a young boy of 8 years old. We lived in the Arrowhead Subdivision. That afternoon I was around the corner playing with some neighbor kids. I thought I could hear my father calling me, so I ran back to the house. Thinking back now, there is no way I would have been able to hear him. I was too far away for a voice to have traveled in the afternoon noise. Besides, Dad had a very bad case of tonsillitis that day. Like I was saying, I went back home and got through the door just in time to answer the ringing phone. On the other end of the phone was my Mother. Mom was working. She told me she heard a bad storm was on the way. She told me to make sure the garage door was shut and to stay inside. After I hung up the phone, I settled down to watch The Dennis Show. To this day I can vividly remember the electricity going out. I looked out the large window in the living room and didn't have a clue as to what I was looking at.Dad was asleep on the couch, so I woke him up to look. Dad looked and said to get into the bathroom. We sat on the floor. Dad had his back to the door and his feet pushing against the wall opposite the door. I remember that as soon as we sat down, the windows broke. Glass blew under the door, and the sound was tremendous. I know it really didn’t take too long for the tornado to go past, but I do remember the conversation we had in the process. I could feel the cool air rushing under the floor through the crawlspace vents. I asked if we were flying. He said he wasn't sure, but he didn't think we were. He said the house was tearing apart. I asked him how he knew. He said he just knew it was.When things calmed down, we opened the door. The odd feeling I had, looking up the street from inside what once was my hallway, is still with me today.I think back often to that day. I think back and wonder what would have happened if my Dad hadn't been sick that day. Like a lot of kids, I stayed home by myself after school back then. I seriously doubt I would be able to tell you my story, if I had been alone that day. I still live in Xenia and wouldn’t trade this town for any other.Task 10【原文】Undoubtedly, Tibet is one of the harshest places for human existence. It is cool in summer but freezing cold in winter. In Lhasa, the mildest city temperature may exceed 29C in summer while plummeting to -16C in winter! Sun radiation is extremely strong in Tibet. The sunlight in Lhasa is so intense that the city is called Sunlight City. The thin air can neither block off nor retain heat so that the temperature extremes can be met in daytime and the same night respectively in Tibet. However it is not impossible to visit the holy snow land. April to October is the best time to visit Tibet, out of the coldest months, which are from December to February usually. The average temperature in north Tibet is subzero and winter arrives in October until the following May or June. July and August are the best time to visit the area, enjoying warm temperature, intense sunshine, beautiful scenery and festive events. May, June and September is the tourist season in east Tibet. In winter, roads are all blocked by heavy snow. Landslides and rock falls frequently occur, which will make travel difficult.。
Since the voice of love entered junior high school, it felt that there was a thick and transparent wall between her and her parents, and she spent little time together. Every time I go home, my parents ask for help and understand the school situation. One night. Because I was a little tired just after the holiday, I went to bed after eating and washing, while my mother was still busy doing housework (before I went to bed). At night, the bright moonlight sprinkled into my bedroom, and I had already entered a sweet dream. Suddenly, I felt a figure nearby. When I wanted to open my bleary eyes, I was completely controlled by my 'mind' ---- I couldn't open my eyes. Because when I am around my mother, she likes to watch my sleeping posture, which has always been the imprint of love she left for me. I don't want to disturb my mother's silent wishes and silent expectations. I understand: at this time, the blue sky silently protects the white clouds; At this time, the sea silently cherishes the reef; This is the silent expectation of the river bed for small fish; This is the mainland's meticulous care for flowers and plants. I was wrapped by my mother's silent eyes. After a while, mother turned off the light and walked back to the room. In the bright moonlight, I noticed that the blue sky was not bright, the sea was not surging, the river bed was no longer high, and the mainland was no longer tall. My mother's upright body like a tree had become bent. Countless silver hair was mixed with her dark bright hair, which was more beautiful against the moonlight. I understood my mother's silent voice. This is the "voice" of encouragement. This is the "voice" of expectation. I cherish my mother's "voice" more and study hard. Under the influence of my parents, I became more fond of learning and reading. The sound of flute is clear, the sound of flute is deep, and the sound of zither and bamboo is intoxicating. But I think the sound of books is more charming than them. Only the heart can hear the sound of books. I tasted the sound of books like sucking the mother liquor... The yellowed and old pages exude the flavor of ancient history, and the magnificent and classic works waft the flavor of cross era. Hold a book in your hand, concentrate on it, taste it calmly, and slowly feel the soft voice rippling in the book... The voice of the book reflects its long, passionate, clear and contains a thousand years of history. The voice of the book contains: Meng Haoran's guilt of "sitting and watching the anglers, admiring the fish in vain"; Li Shangyin's homesickness about "how to cut the candles in the west window, but talk about the night rain in Bashan"; Du Fu's sorrow for his country was that he died before he left the army, which made the heroes full of tears; Li Bai "waved away from here, and the horses in Xiaoxiao's class were singing"; Wang Wei's indifference to "the moon shines among the pines, and the clear spring stone flows upward"; Gong Zizhen's silent dedication of "falling red is not a heartless thing, but turns into a spring mud to protect flowers"; There is Wen Tianxiang's national integrity of "who has never died since ancient times, stay loyal to history". In the book, we can express the aspirations of all people, and also make all people enjoy themselves there. I understood the voice of books in silent love, and found the true meaning of the voice of love in the voice of books. Two in one, let me enjoy the elegance of voice。

a rXiv:as tr o-ph/12126v16Dec2**TITLE**ASP Conference Series,Vol.**VOLUME**,**PUBLICATION YEAR****EDITORS**The Nuclei of Nearby Radio-Loud Ellipticals G.A.Verdoes Kleijn,P.T.de Zeeuw Leiden Observatory,Postbus 9513,2300RA,Leiden,The Netherlands S.A.Baum,C.P.O’Dea,R.P.van der Marel,C.Xu Space Telescope Science Institute,3700San Martin Drive,Baltimore,MD 21218,USA C.M.Carollo,J.Noel-Storr Columbia University,Dept.of Astronomy,New York,NY 10027,USA Abstract.We have observed a complete sample of 21nearby (D <70h −1Mpc)Fanaroff&Riley Type I galaxies with HST/WFPC2and de-tected dust disks and lanes in 19of them.The radio jets are roughly perpendicular to the dust which is used to constrain the Doppler boost-ing factors of the radio jet and cores.The VLBA core flux correlates with the central H α+[NII]flux which might indicate that the VLBA core is dominated by an isotropic component.Twelve galaxies show nuclear optical sources.We discuss various possible origins for this emission.1.Introduction The Fanaroff&Riley Type I (FR I)radio galaxies in the nearby (z <0.03)universe can be characterized as early-type galaxies with jets emanating from an AGN which is powered by a black hole (BH).These AGN display only weak nuclear optical line and continuum emission.The FR I stellar hosts and theirunresolved cores bear resemblance to both normal early-type galaxies with radio cores,which constitute a considerable fraction of the nearby early-type popu-lation (∼50%at M B =−22,cf.Sadler 1997)and to early-type galaxies with unresolved blue optical spikes (Carollo et al.1997).On the other hand,the FR I galaxies appear to be scaled-down versions of powerful radio galaxies and quasars in the distant universe which have strong nuclear optical line and con-tinuum emission.For a physical understanding of the connection between active and normal galaxies,it is important to determine how these low-luminosity ac-tive nuclei and their jets form and evolve.Relevant questions are then:where did the accreted matter come from,how does this accretion trigger jet forma-tion,and what is the origin of the optical AGN luminosity?We are using HST to study the centers of a complete sample of FR I radio galaxies and to isolate weak optical nuclear activity from the stellar background (Verdoes Kleijn et al.1999).Here we discuss further interpretation of the WFPC2data in combination with VLBA radio data presented by Xu et al.(2000).12Verdoes Kleijn et al.Figure1.Left and middle:V-band images of two sample galaxies.NGC193has a dust lane and NGC383has a dust disk.Both galaxieshave a blue nuclear optical source.Right:the axis ratio of the dustdisk plotted versus the range of the angleαbetween the sides of thedust disk symmetry axis and the radio-jet axis,that are closest to thedirection of the line of sight.Horizontal bars indicate the allowed rangeforαand the solid dots indicate the medianα.2.Orientation of Dust and Radio JetsWe detected dust in the centres of19galaxies(Fig.1).The dust extent ranges from a few hundred pc to a few kpc.In eleven galaxies,the dust morphologyis smooth and elliptical(a‘disk’),while in eight galaxies it isfilamentary with wisps and bends(a‘lane’).Lanes are roughly perpendicular to the radio jets:the position angle difference∆PA is in the range68◦−90◦.Processes that cause such a preferred orientation are discussed in e.g.,Quillen&Bower(1999).By contrast,all disks closely align with the galaxy major axis.The∆PA of the diskmajor axis and radio jet is in the range range23◦−90◦.One can assume that(i) dust disks are circular and(ii)the brightest side of the radio jet is approaching the observer.The allowed range of the intrinsic angleαbetween the sides of both the dust disk symmetry axis and the radio jet axis that are closest to the direction of the line of sight,can then be computed.By definition,the radio jet inclination is in the range0◦−90◦,butαcan take a value in the range0◦−180◦. The right panel in Fig.1shows that the allowed range ofαfor each dust disk is constrained such that the dust disk symmetry axis and the radio jet axis tend to‘align’(i.e.,α<90◦).Further analysis indicates that the angle with the line of sight for jet and disk are expected to differ typically by only∼10◦−20◦.A similar result was derived by Capetti&Celotti(1999)for a small pilot sample.3.Doppler Boosting of Radio Jets and CoresXu et al.(2000)report the surface brightness ratio S of VLBA jet and counter jet at1670MHz for the sample galaxies.If the jets are intrinsically symmetric and ejected in opposite directions,S depends on jet inclination and velocity(e.g., Urry&Padovani1995).As discussed in the previous section,the dust disk inclination is a reasonable estimator for the jet inclination and can constrain theThe Nuclei of Nearby Radio-Loud Ellipticals3Figure2.Left:the VLBA jet to counter jet surface brightness ra-tio S versus dust disk inclination.The arrows indicate lower limits.The curves describe S for an isotropic continous jet with no preferreddirection of the magneticfield,a radio spectral indexα=0.75andγ=1.1(solid line),γ=2.0(dotted line)andγ=10.0(dashed line).The horizontal error bars indicate the uncertainty in the jet inclination.Middle:Hα+[NII]flux in the central1′′versus VLBA coreflux(1670MHz).Right:flux of the nuclear optical sources(I-band)detectionsand upper limits versus VLBA coreflux.jet velocity.Fig.2plots S versus jet inclination together with model predictions for constant jet velocity v,assuming an isotropic continuous jet with no preferreddirection of the magneticfield and a radio spectral indexα=0.75(fν∼ν−α) typical for jets.The observed values of S cannot constrain v very well given thatmost are lower limits(i.e.,the counter jet is not observed)and given the∼20◦uncertainty of the jet inclination.For NGC315we can constrain the Lorentz factor to beγ>10.The VLBA radio-coreflux(unresolved at the parsec scale)correlates tightly with central Hα+[NII]flux(Fig.2).Interestingly,a similar correlation is found for radio-core galaxies(Ho1999).If the Hα+[NII]flux is emitted isotropically and correlates tightly with intrinsic VLBA coreflux,the observed scatter in the correlation might be due to Doppler boosting.The low scatter in the correlation then constrainsγ<2.Indeed,no dependence of the VLBA coreflux on dust disk inclination is found.Thus it seems that the VLBA coreflux is dominated by a relatively isotropic component instead of a relativistic jet.This isotropic component might have uncollimated relativistic motion.4.Nuclear Optical SourcesTwelve galaxies show blue nuclear optical sources(NOS)unresolved with WFPC2, corresponding to sizes of tens of parsec or less.The right panel in Fig.2shows NOSflux versus VLBA radio coreflux.The observed correlation is significant at the99.999%level(generalized Kendall’s Tau test).This agrees with results by Chiaberge,Capetti,&Celotti(1999).Radio core emission is generally assumed to be self-absorped synchrotron emission.The correlation might indicate that the NOS is also synchrotron emission.The radio-to-optical spectral index varies4Verdoes Kleijn et al.between0.43and0.85.These values are consistent with those found for galaxies in our sample with extended optical jets:3C66B,3C31and M87(Butcher,van Breugel&Miley1980;Biretta,Stern,&Harris1991).The slope of the log-log correlation,s=1.04±0.24,although not well determined,is consistent with a power-law spectral energy distribution(SED)from radio to optical wavelengths.Alternatively,the NOS might be emission from the accretion disk and/or flow.For example,Di Matteo et al.(2000)obtain a reasonablefit to the nuclear radio to X-ray SED of M87using an ADAF model with matter outflow.However, the models thatfit the observed X-ray SED underpredict the nuclear optical emission by a factor of∼4.Furthermore,Di Matteo et al.note evidence for a contribution to theflux by the synchrotron jet at radio and millimeterfluxes. If the accretion disk is inside an optically thick torus,the NOS detection rate implies an opening angle∼130◦.Broad emission-line regions are commonly detected in powerful AGN but typically not detected in FR Is.The large opening angle would then suggest BLRs are generally not present in FR I galaxies Finally,the NOS might be produced by a nuclear starburst.The high NOS detection rate would require a continuous starburst on time scales on the order of the radio-source lifetime,typically estimated to be107−8yr(cf.Chiaberge, Capetti,&Celotti1999).However,detailed studies of the optical nuclear spec-tra of M87and M84indicate their NOS are indeed not produced by a starburst but by non-thermal AGN emission(Kormendy1992;van der Marel1994;Bower et al.2000).ReferencesBiretta,J.A.,Stern,C.P.,&Harris,D.E.1991,AJ,101,1632Bower,G.A.,et al.2000,ApJ,534,189Butcher,H.R.,van Breugel,W.,&Miley,G.K.1980,ApJ,235,749 Capetti,A.,&Celotti,A.1999,MNRAS,304,434Carollo,C.M.,Franx,M.,Illingworth,G.D.,&Forbes,D.A.1997ApJ481,710 Chiaberge,M.,Capetti,A.,&Celotti,A.1999,A&A,349,77Di Matteo,T.,Quataert,E.,Allen,S.W.,Narayan,R.,&Fabian,A.C.2000, MNRAS,311,507Ho,L.C.1999,ApJ,510,631Kormendy,J.1992,ApJ,388,L9Quillen,A.C.,Bower,G.A.1999,ApJ,522,718Sadler,E.M.1997,in ASP Conf.Ser.Vol.115,The Nature of Elliptical Galaxies, ed.M.Arnaboldi,G.S.Da Costa,&P.Saha(San Fransisco:ASP),411 Urry,C.M.,Padovani,P.1995,PASP,107,803van der Marel,R.P.1994,MNRAS,270,271Verdoes Kleijn,G.A.,Baum,S.A.,de Zeeuw,P.T.,O’Dea,C.P.1999,AJ,118, 2592Xu,C.,Baum,S.A.,O’Dea,C.P.,Wrobel,J.M.,&Condon,J.J.2000,AJ, submitted(astro-ph/0009124)。
