One of my good childhood memories was dinner with my parents and two sisters. Because my husband and I both worked and our three children were busy with their studies, we seldom had a chance to get together as a fam¬ily. But we thought it would be possible for us to sit down and enjoy meals together every week. First we tried setting fixed days: Mondays, Wednesdays, and Fridays. But almost everyone was unhappy. Then my son had the idea that everyone told his or her most convenient days and I would choose the two best days. For a while the children were still unhappy with the idea. They said they would rather spend the time with their friends playing sports. Gradually, though, they began to see the evenings together as interesting and helpful. We loved a lot. We made plans for trips. We discussed each other’s problems. After a couple of months anyone who had to miss a family meal felt regretful. And now we all feel than we have been able to build stronger relationships within the family that we had before.答案:1-5:BACBC 6-10:ABABC 11-15:ACABA 16-20:ACBBC 21-25:CBADC。

We have investigated a range of different models to see which is the best value for money. After a number of different tests and interviews with people who are familiar with the different cameras being assessed, our researchers recommend the Olympic BY model as the best auto-focus camera available at the moment. It costs $200 although you may well want to spend more—perhaps as much as another $200—on buying additional lenses and other equipment. It is a good Japanese camera, easy to use. Equivalent German models tend to be heavier and slightly less easy to use, whereas the American versions are considerably more expensive. The Olympic BY model weighs only 320 grams which is quite a bit less than other cameras of a similar type. Indeed one of the other models we looked at weighed almost twice as much. Similarly, it is smaller than most of its competitors, thus fitting easily into a pocket or a handbag. All the people we interviewed expressed almost total satisfaction with it.

And, in the end, you have to write aresearch p aper, right? Then what is writing aresearch paper like? How are we going to w rite one?What are the steps in producing a research paper and what are the p oints we need to take careof? In today’s lecture, I’ll try to answer these questi ons.First of all, what is writing a research paper like? We may start by comparing i t to an ordinaryessay, a form of writing you are very familiar with. Writing a r esearch paper is much like writingan essay. Both kinds of writing involve ma ny of the same basic steps. That is, choosing atopic, asking questions to defi ne and develop the topic, identifying the audience, getting rawmaterial to wor k with, outlining the paper, writing it, and, finally, revising it. These are the st epsshared between research paper writing and essay writing.Is there any difference, you may ask. Yes. What makes a research paper diffe rent is that muchof your raw material comes not from your own head, but from printed sources: mainly booksand periodicals in the library. Collecting raw material, that is reading books and taking notes, isvery much like the process of brainstorming at the prewriting stage of an ordinary essay.Generally speaking, there are two basic types of research papers, and a paper may belong toeither type. It may be a survey of facts and opinions availabl e on a given topic or an analytical argument that uses those facts and opinio ns to prove a point. Your instructor maytell you which kind of paper you are e xpected to write. If not, you yourself should eventually choose between surv eying and arguing. You will then have a definite way of managing yoursource s.Now, let’s take a look at how you are going to write a survey-type research p aper or an argumentative research paper. In a survey-type research paper, you gather facts and a variety of opinions on a given topic. You make little at tempt to interpret or evaluate whatyour sources say or to prove a particul ar point. Instead, through quotation, summary, and paraphrase, you try to provide a representative sampling of facts and opinions to give an objecti ve report on your topic. You explain the pros and cons of various attitudes or opinions,but you don’t side definitely with any one of them.While in an argumentative research paper, you do considerably more. You d o not simply quote, paraphrase, and summarize as you do in a survey-typ e paper. You interpret,question, compare, and judge the statements you cite . You explain why one opinion is soundand another is not; why one fact is rel evant and another is not; why one writer is correct andanother is mistaken. What’s more, your purpose may vary with your topic. You may try toexplain a situation to recommend a course of action, to reveal the solution to a pro blem, orto present and defend a particular interpretation of a historical ev ent or a work of art. Butwhether the topic is space travel or trends in contem porary American literature, an argumentative research paper deals actively – I say it again, actively – with the statements itcites. It makes these stateme nts work together in an argument that you create, that is, to anargument lea ding to a conclusion of your own.In the next part of the lecture, I’d like to talk about one of the basic steps in writing Imentioned earlier in the lecture. That is how to choose a topic. Choos ing a topic for a researchpaper is in some ways like choosing a topic for an ordinary essay, but there are somedifferences. As you think about your topic, as k yourself these questions:Question number one: Do you really want to know more about this topic? This is the initial question you have to ask yourself, because research on any subj ect will keep you busy forweeks. You certainly do not wish to waste your time on something you have little interest in.You do it well only if you expect to lea rn something interesting or important in the process.Question number tw Are you likely to find many sources of information on this topic? Youcannot write a research paper without consulting a variety of sour ces. If only one source ornone at all is readily available, you should rethink your topic or choose another.Question number three: Can you cut the topic down to a manageable size? Be reasonable and realistic about what you can do in a short period, say, tw o to four weeks. If your topic is“The American Revolution”,you’ll scarcely hav e time to make a list of books on your subject, letalone read and analyze the m. So try to find something specific, such as “The Role of ThomasJefferson i n the American Revolution” or “The Franco-American Alliance”Question number four: What questions can you ask about the topic itself? Qu estions help youget the topic down to a manageable size, discover its possibi lities, and find the goal of yourresearch, that is, the specific problem you wa nt to investigate. Suppose you want to writeabout the issue of financing a college education – A topic not only current, but also directlylinked to the liv es of most college students and their families. You could ask at least two orthr ee pointed questions: How much does educational opportunity depend on fin ancial status?Is financial aid going to the students who need it most? How m uch should universities andcolleges charge their students? You can ask yourse lf these questions or more as you start workon the research paper.Okay. To sum up, in today’s lecture, we’ve looked at some of the issues in res earch paperwriting, like the basic steps, types of research paper, and how to c hoose a topic. In our nextlecture, we’ll concentrate on how to identify the a udience, how to work out an outline, andhow to edit the draft.Section B, InterviewM: Today, we’ve Professor McKay on our morning talk show. Good morning, Professor McKay.W: Good morning.M: I’ve heard that you and your team have just completed a report on old ag e.W: T hat’s right.M: Could you tell me what your report is about?W: Well, the report basically looks into the various beliefs that people hold ab out old age andtries to verify them.M: And what do you think your report can achieve?W: We hope that it will somehow help people to change their feelings about ol d age. Theproblem is that far too many of us believe that most old people are poor, lonely, and unhappy.As a result, we tend to find old people, as a grou p, unattractive. And this is very dangerousfor our society.M: But surely we cannot escape the fact that many old people are lonely and many are sick.W: No, we can’t. But we must also remember that the proportion of such pe ople is no greateramong the 60-70 age group than among the 50-60 age gro up.M: In other words, there is no more mental illness, for example, among the 60s-70s thanamong the 50s-60s.W: Right! And why should there be? Why should we expect people to suddenl y change whenthey reach their 60th or 60th birthday any more than they did when they reached their 21st?M: But one would expect there to be more physical illness among old people, surely.W: Why should one expect this? After all, those people who reach the age of 65 or 70 are thestrong among us. The weak die mainly in childhood, then in t heir 40s and 50s. Furthermore, bythe time people reach 60 or 65, they have l earned how to look after themselves. They keepwarm, sleep regular hours, an d eat sensibly. Of course, some old people do suffer fromphysical illnesses, b ut these do not suddenly develop on their 65th birthday. People who arehealthy in middle age tend to be healthy in old age, just as one would expect.M: Do you find that young people these days are not as concerned about the ir parents astheir parents were about theirs?W: We have found nothing that suggests that family feeling is either dying or dead. There donot appear to be large numbers of young people who are tryin g, for example, to have their dearold mother locked up in a mental hospital.M: Don’t many more parents live apart from their married children then used to be the case?W: True, but this is because many more young families can afford to own thei r own homesthese days than ever before. In other words, parents and their m arried children usually live in separate households because they prefer it that way, not because the children refuse to havemum and dad living with them.M: Is this a good thing, do you think?W: I think that it’s an excellent arrangement. We all like to keep part of our l ives private, evenfrom those we love dearly. I certainly don’t think that it’s a s ign of the increased loneliness ofold age.M: Are people’s mental abilities affected by old age?W: Certain changes do take place as we grow older, but this happens through out life. Thesechanges are very gradual and happen at different times with dif ferent people, but, in general, ifyou know a person well in his middle age and have seen how he deals with events andproblems, you will easily recognize him in old age.M: So that someone who enjoys new experiences, travel, education, and so o n in his middleyears will usually continue to do so into old age?W: Exactly. We have carried out some very interesting experiments in which a group of peopleaged 60-70 and a group aged 30-40 had to learn the same th ings. The first thing wediscovered was that the young group tends to be quick er at learning than the old group.However, although the old group took longer to learn, eventually, they performed as well asthe young group. And when we tested the two groups several weeks later, there was again nodifference b etween the two groups.M: That’s very interesting indeed. What else did your experiments show?W: Well, one group of old people agreed to attend evening classes for a year t o study Englishand mathematics. In fact, most of this group became so intere sted in their studies that theycontinued them for another year. Anyway, we di scovered that they did best in the Englishclasses and that most of them steadi ly improved their ability to communicate in both thewritten and the spoken l anguage.M: What about the group who studied mathematics?W: Well, that’s a different story. There seems to be no doubt that people find maths moredifficult as they grow older. Though, why this is so, I cannot say.M: Perhaps pocket calculators will solve this problem.W: I think you’re right. In fact, I’m sure that you are.M: Okay. Time for a commercial. Stay tuned; we’ll be right back.Section C: News ItemsQuestion 6M: Scientists in Brazil claim they’ve come up with a new way of treating burn s. That is, withfrog skin. Researchers say it is cheap and effective. The frog s kin has components that diminish the growth of bacteria, making the wound heal faster and reducing the amount oftime that patient has to stay in hospit al. Researchers said the method had already beensuccessfully used in some h ospitals in Brazil.Question 7W: Once a source of high-pitched business activity, Japan’s karaoke industry has slowed down.Japanese have less to sing about amid sustained economic problems. Karaoke firms are now striving to develop new ideas to attract cos t-conscious karaoke singers. These include a new,high-tech machine that all ows people to sing like famous singers and theme rooms on some ofthe Asia n cartoon figures targeted at younger crowds. The new karaoke machine is b eingdeveloped by a professor from the US Massachusetts Institute of Technolo gy. The machineuses a technology called C-Sound that automatically adjuststhe speed and tone of any songbeing played to match the tempo and key th e singer is using. The tempo can be adjusted manually on conventional kar aoke machines, but the new product is the first machine to do it automaticall y.Question 8M: The China Internet Network Information Center said this week that the nat ion’s online community is expanding at a rapid pace, with 8.9 million users added in the first half of theyear, from January to June. China’s Internet popu lation hit 68 million by the end of June, theworld’s second-largest figure afte r the United States. The figure was 10 million at the end of2000 and 1.5 milli on in 1997.“Cyberspace is a force to be reckoned with in China,” said ChenHua Lin, a sen ior Internet analyst at the Chinese Academy of Sciences.

听力原文2005PART Ⅱ LISTENING COMPREHENSIONSECTION A CONVERSA TIONSQuestions 1 to 3 are based on the following conversation.W: Good morning. Sit down please, Mr. Johnson.M: Thank you, madam.W: I have read your letter here. You seemed to have done very well at school. Can you tell me something about your school work?M: As you can see, my strongest subjects were arts subjects. My best subject was history and my second best was geography. However, my favorite subject was math, and the results I got in the math paper were quite reasonable.W: That's true. Now, can you tell me why you think these subjects will help you in this job?M: Well, madam, I understand that you manufacture computers, prepare software, and advise clients on how to use them. Is that right?W: That's right.M: And I've been told that working with computers needs a logical mind rather than great skills in mathematics. That's especially true, I believe, when it comes to writing programs. So I think my results show that I have some ability in logic and in mathematics as well.W: So, you would like to write material for computers, would you?M: Yes, madam. That's what interests me most about computers - writing programs, but I think the computer industry itself is still expanding enormously. I'm sure that career prospects in the industry would be very good no matter what sort of job I went into.W: I see, well, thank you. I've enjoyed our talk. We'll be writing to you.M: Thank you, madam. Good morning.Questions 4 to 7 are based on the following conversation.W: Excuse me. Could I ask you some questions?M: Of course.W: I work for an advertising agency and I'm doing some research. It's for a new magazine for people like you.M: People like me? What do you mean?W: People between 25 and 35 years old.M: Ok.W: Right. Urn, what do you do at the weekend?M: Well, on Fridays, my wife always goes to her exercise class. Then, she visits friends.W: Don't you go out?M: Not on Fridays. I never go out on Fridays. I stay at home and watch television.W: And on Saturdays?M: On Saturdays my wife and I always go sailing together.W: Really?M: Mm, we love it. We never miss it. And then, in the evening, we go out.W: Where to?M: Different places. We sometimes go and see friends. We sometimes go to the cinema or restaurants. But we always go out on Saturday evenings.W: I see. And now Sunday. What happens on Sundays?M: Nothing special. We often go for a walk. And I always cook a big Sunday lunch.W: Oh. How often do you do the cooking?M: Urn, twice a week.., three times a week...W: Thank you very much. All I need now are your personal details, your name, job and so on. What's your surname?M: Robinson.Questions 8 to 10 are based on the following conversation.M: Parcel Express, good morning! How can I help you?W: Good morning. I'm thinking of sending a parcel to New York next week. Can you tell me what the procedure is, please?M: Certainly. When you ring us, we need the following information. The invoice address: that's probably your address, isn't it? And then, the pickup address. That's different. And the contact phone number.W: Just a moment. I'm taking notes. Phone number, right.M: Then we need the full name, address and phone number of the person you are sending the parcel to.W: Ok, anything else?M: Yes, the weight and dimensions of the parcel. That's height, weight and length. And the value of the goods and full description.W: Value, description.M: Yes, but don't seal the parcel. You need to leave it open so that the driver can check the contents when he collects it. After the recent bombing, the airline said that we'd have to check all parcels. They told us we had to do it.W: Fine. Now last question. How long will the parcel take to get to New York?M: One to two working days. There are daily flights at midday. And if we collect the parcel from you at 10:15 then your parcel catches that flight and it will arrive in 24 hours.W: Right. Thank you very much. You've been very helpful.M: Not at all. Goodbye.W: Goodbye.SECTION B PASSAGESQuestions 11 to 13 are based on the following announcement.Attention, all passengers, platform change! This is a platform change. The train now standing at Platform 9 is the 10:48 train calling at all stations to Nanjing. Please note the train on Platform 9 is not the 10:52 train to Jinan. It's the 10:48 train calling at all stations to Nanjing. The 10:52 to Jinan will now leave from Platform 7. Train announcement, the 11:20 train to Zhengzhou from Platform 8 will be subject to a 15-minute delay. I re peat there will be a 15-minute delay for the Zhengzhou train on Platform 8. It will now leave at 11:35, not 11: 20. The 11:28 train to Hangzhou has been cancelled. We apologize to customers, but due to signal problems, the 11:28 train to Hangzhou from Platform 15 has been cancelled. The 11:32 train to Tianjin is now standing at Platform 13. Please note, there will be no restaurant car on this train. I repeat: there will be no restaurant car on the 11:32 to Tianjin now standing at Platform 13.Questions 14 to 16 are based on the following passage.The International Red Cross in Red Crescent Museum was opened in Geneva in 1988.It tells the story of men and women who in the course of the major events of the last 150 years have given assistance to victims of war and natural disasters. The organization was established in 1863 and was based on the idea by a Swiss businessman called Henry Durant. He had witnessed the heavy casualties of the battle of Solferino in Italy four years earlier, in which 40,000 people were killed, wounded or missing. He had seen the lack of medical services in the great suffering of many of the wounded who simply died from lack of care. The International Red Cross or Red Crescent exists to help the victims of conflicts and disasters regardless of their nationalities. The symbol of the organization was originally just a red cross. It has no religious significance. The founders of the movement adopted it as a tribute to Switzerland. However, during the rest of the Turkish war, the Turks felt that the cross could be seen as a fence to the Muslim soldiers and the second symbol, the red crescent, was adopted for use by national organizations in the Islamic world. Both are now official symbols.Questions 17 to 20 are based on the following passage.At major college or high school sports events, cheerleaders, both male and female, jump and dance in front of the crowd, and shout the name of their team, running around, yelling "Go Team Go!" The first cheerleader ever was a man. In 1898, Johnny Campbell jumped in front of the crowd at the university of Minnesota and shouted for his team. He shouted "Hurrah, Minnesota!" This was the first organized show, or yell. For the next 32 years, cheerleaders were men only. Cheerleading is not just about cheering. They practice special shows, dances, and athletic shows. The men throw the women high in the air, and catch them. The team members climb on each other's shoulders to make a human pyramid. They yell and dance too. It is like human fire works. Of course, they may often suffer serious knee and wrist injuries and bloody noses. Cheerleaders have their own contests every year at local, state and national levels. And a crowd shouts for them. It is not fair to think cheerleading is just being cheerful and lively and having a loud voice. Cheerleading is a sport in itself.SECTION C NEWS BROADCASTQuestions 21 and 22 are based on the following news.The bodies of dozens of African emigrants discovered off the Italian coast last week might have been thrown overboard, Italian officials said on Monday. A coast guard spokesman said 15 illegal emigrants, all believed to come from Somalia, survived being thrown into the Mediterranean sea. But one of the survivors, a woman, was in a serious condition.

Looks like you were here early.M: Y eah. Class doesn't start in ten more minutes, so I put up another one reading.W: What is it?M: It is called Sister Carrie. It is about a woman named Carrie who leaves yore country home to () living in Chicago and New Y ork.W: Oh, I've studied theatre of Dreiser. His work is a little depressing, but I like him, even though his characters always get in trouble. He treats some with sympathy. How do you like Sister Carrie? M: It's not what I expected. On the back covering says the book created a lot of controversy when it was first published in 1900. It even says the publish was dropped from the market after only 500 copies were sold. But I don't see why.W: Well. The novel might not be shocking by our standard but it sure created a disturbance then. Think about what Carrie does. She leaves yore country home and gets call-up and some personal scandals in the city. Now most of the other authors of that time would punish the character to provide a moral lesson, but Dreiser has Carrie become a successful actor at the end.M: Wow, that puts the story in a different perspective. (...) Dreiser must have been discouraged when the publish took off from the market.W: He sure ws. He started writing fictions for a while and did work as a journalist then an editor. M: Well, how did the book become recognized?W: Some British reviewers praised the novel and then another publisher released it in 1907. Eventually people recognized the novel for its realism and Dreiser went on to write other successful works.31. What is the conversation mainly about?32. According to the woman, how is Sister Carrie different from other novels at that time?33. How did Sister Carrie eventually gain recognition?Question34-38Listen to part of the discussion in a linguistics classM: Before we began today's topic, I'd like to review the phases of child language acquisition that we went over yesterday. Who'd like to summarize first? Y es, Lisa.W:Well, first of all, you said that new borns only make rudimentary vocalizations because the voice box isn't in position for speech yet. But that at about three month of age baby starts to utter the first sounds that resemble language sounds. The sounds of consonants like "k" and "g".M: That's right. And after this stage come the meaning of symlobols, a consonant followed by a vowel. For example, the "dada" sound. And the next stage comes a real breakthrough. Can you tell us about that, Lisa.W: Well, between six months and one year of age, babies begin to associate sounds with meaning. So, when you say "dog", they know you're referring to the four-leg animal that is their house pet. At this stage they start to build a vocabulary. And in a matter of month they are learning ten to twenty new words a day. This vocabulary growth continues until elder lessons.M: Right. and is it amazing that by the time children are two or three years old they are stringing sentences together? Certainly no one would dispute that children had a dramatic capacity for learning language, what linguists are trying to determine is how this language acquisiton takes place.34. What is the class mainly discussing?35. Why does the student mention the sound "k" and "g"?36. According to the student, why are the news born not able to make language like sounds?37. According to the discussion, when the vocabulary growth first starts to increase dramatically?38. According to the discussion, what do the linguists still not know?Part CQuestion 39-41Listen to a talk from a Canadian history classHow did the native communities of the southeasten in Canada convey information to one another? In general, they used courier who memories or messages. Among some peoples, the Iroquois and the Algonquins for example, messagers also used to code based on strings of beads. The beads were called "wanpen" and the color of the beads signify the message. For instance, white beads were used for news of peace, prosperity, or good will. Purple beads meant war, disarster, or death. The couriers also carried messages for early European explorers and missionaries. One Jewish missionary described in history (..s) how a courier memorized 20 different detailed turns actions delivered them to () and then returned with exact what price to each. He had travelled 800 miles round trip. Sometimes the messages were written, not oral and will be passed from one courier to another. When one messager arrived the edge of his tribe's territory, he would sell the letter to the next messager, ususlly at the profit.

This afternoon I'd like to tell you about a less wellknown way to attract birds. It's by putting out eggshells. Many birds eagerly consume them. Perhaps it is a mass of replacing culch and lost by females and (), though I have seen males eat the shells too. Anyway, I have had at leasteight different species of birds come to eat the eggshells. Here is how it's done. Y ou should save your eggshells in winstonman water, then cook them lightly on the baking pan in the oven; set at a low temperature until they are dry but not brown. This stylizes them and makes them brittle. Y ou can quantle them into bisides to pieces and spread them on the ground a rock or a bird seater. Y ou may find them so popular you want to go to your favorite resteraunt to ask for more eggshells.42. What is the talk mainly about?43. Why are the birds attracted to eggshells?44. How are the eggshells prepared?45. How does the preparation process affect the shells?46. What can be inferred about the woman?Question 47-50Listen to part of a talk in the geology classLast week when we talked about landslides, we looked at what causes these huge masses of earth to move down the natural incline such as a mountainside or slope with such distructive force. Now when these landslides occur in populated areas, what can humans do to avoid or minimize damage? Basicly there are three things that can be done. The first thing is to simply avoid construction in the areas where landslides are likely to happen. Typically when a side on the slope is chosen for new construction, it is important that a geological survey of the area be conducted. The survey will reveal unsafe conditions such as too little vegetation or soil that would absorb water too easily, conditions that might lead to a landslide say during periods of heavy rains. The second thing is to build in a way that doesn't make stable slopes unstable. For example, natural vegetation, like grass, is needed to keep soil firmly in place. This vegetation should not be entirely removed since without the grass the soil would loosen up and this could result in a landslide. The third thing is to design good water drainage to ensure that the water naturally runs down the slope and doesn't build up in the soil. This kind of water buildup on the slope is one of the most frequent causes of landslides. Water buildup can easily result during long periods of heavy rain and sometimes the cause is part of the construction itself such as a stonewall that blocks the water from draining off the slope.47. What does the professor mainly discuss?48. According to the professor, why is it important to perform geological surveys?49. What does the professor say about vegetation on the slope?50. According to the professor, what might cause a buildup on the slope?答案详解200505TOEFLADABA ABABB BCDBC DCBAD CBABC DADCC CDACC ADBBC DCBDA CABBD。

He seems to suggest that the poor are robbing the rich.M: He might have used better words to express his ideas. But I've found what he said makes a lot of sense.Q: What does the man mean?3.W: I've been studying all the time, but I still can't see any improvement in my grades.M: Maybe instead of studying in your dorm, you'd better go some place where there are fewer distractions.Q: What does the man advise the woman to do?4.W: The seminar originally scheduled for today has been cancelled.

They had just completed their PR degrees at a nearby university and were thrilled to be hired by one of the finest PR firms in the city. John's first assignment was to create a promotion campaign for a client who was putting a new game on the market. Initially Sue was assigned to work with a sportswear company on a marketing concept for its newest line of clothing. As time passed and work with their respective first clients became more and more difficult, John and Sue realized that they had been assigned two of the toughest clients in town. Although John completed his assignments quickly and successfully, he was furious when he learned that the boss had deliberately assigned him a difficult client. In response he not only complained to his colleagues but also to the boss's secretary. Sue, on the other hand, had a more difficult time satisfying her first client and she took several additional months to actually complete the assignment. However, she just laughed when she heard that the boss had made the assignment purposely. Over the next two years, John worked reluctantly with each assignment and problem that he encountered. Sue accepted each assignment cheerfully. And when problems arose, she responded with her characteristic "No problem, I can handle it." Although Sue took longer to complete her projects than John and both were equally successful on the assignments they completed, Sue was given the first promotion when there came a vacancy.11. What's the relationship between John and Sue now?12. Why was John furious after he finished his first assignment?13. What's Sue's attitude to difficult tasks?14. How does the story end?Passage 2American visitors to Eastern Asia are often surprised and puzzled by how Asian cultures and customs differ from those in the United States. What's considered typical or proper social conduct in one country may be regard as odd, improper or even rude in the other. For example, people from some Eastern Asian countries may begin a conversation with a stranger by asking personal questions about family, home or work. Such questions are thought to be friendly, whereas they might be considered offensive in the United States. On the other hand, people in most Asian cultures are far more guarded about expressing their feelings publicly than most Americans are.Openly displaying annoyance or anger, yelling, arguing loudly and so forth is considered ill-mannered in countries such as Japan. Many Eastern Asians prefer to hold their emotions in check and instead express themselves with great politeness. They try not to be blunt and avoid making direct criticisms. In fact, they often keep their differences of opinion to themselves and merely smile and remain silent rather than engage in a confrontation. By comparison, Americans are often frank about displaying both positive and negative emotions on the street and in other public places. Americans visiting Asia should keep in mind that such behavior may cause offense.A major difference between Americans culture and most Eastern Asian cultures is that in Eastern Asia, the community is more important than the individual. Most Americans are considered a success when they make a name for themselves.15. How would some Asians start their conversation when they meet for the first time?16. What would a Japanese do when he feels annoyed?17. What is encouraged in American culture according to the passage?Passage 3In order for a chemical to be considered a drug, it must have the capacity to affect how the body works. No substance that has the power to do this is completely safe. Drugs are approved only after tests have demonstrated that they are relatively safe when used as directed and when their benefits outweigh their risks. Thus some very dangerous drugs are approved because they are necessary to treat serious illnesses. Many people suffer ill effects from drugs called side effects, even though they take the drug exactly as directed. The human population contains a great variety of genetic variation, but drugs are tested on just a few thousand people. When a particular drug is taken by millions, some people may not respond in a predictable way, even though the drug has been tested. A patient may also acquire a tolerance for a certain drug, which means the patient has to take ever larger doses to produce the desired effect. Tolerance may lead to habituation, in which the person becomes so dependent on the drug that he or she becomes addicted to it. Addition causes severe psychological and physical disturbances when the drug is taken away. Finally, drugs often have unwanted side effects. This usually causes only minor discomfort, such as a skin rash, headache or sleepiness. Certain drugs, however, can produce serious adverse reactions.18. Under what circumstances are drugs approved?19. Why do many people suffer side effects from a drug even though they take it as directed?20. What will happen when patients acquire a tolerance for a certain drug?。

But I wanna take you back to a time when newspapers first started to be printed in the United States, well, back then they were still British colonies. Anyway let’s discuss for a moment the role newspapers played in colonial times, Er, about around the 1700’s. Before that time, there were of course many printed materials, the books certainly but. ..but also pamphlets, government and legal documents, things of this sort. The first colonial newspape r to appear was not what we would expect today, it’s only one small sheet printed on two sides. It was also different from United States’ newspapers today in that all news had be officially approved by the governor before printing. And early printer name James Franklin, took a courageous step by starting an independent newspaper. Franklin, who owned his own printing press, wanted to be free form outside control above all, he wanted the paper to entertain the people with humors and critical news items. Frank lin’s newspaper was especially significant because literacy was increasing at the time, even those who weren’t able to read or expose to the information in the newspapers by hearing it. Newspapers were read loud everywhere, in homes, workshops and taverns. By the mid 1700, there were more than a dozen colonial newspapers what James Franklin began was a tradition of the independent press where ideas and information spread quickly, and humor and different opinions were tolerated.Q39. What is the talk mainly about?Q40. According to the professor, why did James Franklin start independent newspaper? Q41. How did James Franklin’s newspaper different from the previous newspaper in colonies?Q42. What does the professor say about the colonists who unable to read?Q43-46Let’s move the discussion away from Jupiter itself and look at its moons. Now there is one in particular that spend in the news recently and that’s Ganymede. We’ve known for a long time that Ganymede is the largest moon in the solar system. But in 1996, the Galileo aerospace probe sent back the information showing us the Ganymede in many ways. Behaves like a full fledged planet. Now Ganymede is larger than Mercury, and about half the size of earth. It’s covered with ice and some dark rocky debris. While Galileo has showed us though is that Ganymede’s surface is deeply wrinkled with ridges and fissures. A sign that it experiences some of the same dynamic forces that move continents and cause quake on earth. But Galileo detected an even bigger surprise for scientists. Ganymede appears to generate its own magnetic field. That’s a planet like quality that set it apart from all other moons. Now what causes this magnetic field is a matter of the debate for scientists. But there are a couple of possibilities .It could mean that despite its cold exterior,Ganymede has a core of a molten metal inside it generating the magnetic field. That’s what causes the earth’s magnetic field. Or it could mean that there is a thin layer of salty water conducting electricit y just beneath Ganymede’s surface. Something else Galileo was able to detect does it flew by Ganymede was sudden increase in the density of electrical charge particles. Now what this indicates is the presence of atmosphere, which in turn has let scientists to believe that Ganymede has some sort of atmosphere, however thin it maybe.Q43. What is the main topic of the lecture?Q44. What does the speaker say makes Ganymede different from all the moons?Q45. According to the speaker, what may lie deep under the surface of Ganymede. Q46. What does the speaker say about the electrically charged particles that were detected near Ganymede.Q47-50Let’s talk the environmental issue that has to do with how common household products have changed. More and more products contain bacterial killing chemicals these days. These antibacterial chemicals aren’t just in product like soap. They are in all sorts of household cleaners and toothpaste. And if you think about it for second you will realize that most of those chemicals just end up going down the drain. But you are probably thinking that all that stuff go through a treatment plan that removes chemicals, right? After all that’s what happens to stuff that goes down the drain. Well, waste water is treated, but that doesn’t usually remove all the chemicals in it. The chemicals left in the treated water get into the aquatic environment.That is into the rivers, and streams where plants and fish and other animals live. Now to find out the affect of antibacterial chemicals on fresh water ecosystems, a study was done with algae, which are tiny plant like organisms .Different spices algae were taken to a lab and the expose to just a few antibacterial chemicals found in the streams. And guess what? In the experiment, the overall gross of algae and the number of spices dropped. This is not good and here is why. Algae are the base of the aquatic of food chain, which means that other organisms depend on them for food. So if the chemicals kill algae at the bottom of the food chain, the whole system is being disrupted.Q47. What is the professor mainly discussing?Q48. According to the professor, how have household products changed?Q49. What does the professor say about the treatment of waste water?Q50. What does the subject mentioned by the professor?。
