The year at an American college is divided into 2 semesters or 3 quarters

. Semesters are 15 weeks; quarters are 10 weeks. American college students usually attend school from September to May. They can also study during the summer.

Students choose their classes a few weeks before the start of each term. Universities offer a great many classes in the students’ main area of study and in other areas as well. Students must take both. These include science, mathematics, computer, history and English. Other classes may be just for fun, like dance, theater or sports. Tests usually are given in the middle of the term and at the end. The final examinations are extremely important. In some classes, the professor asks the students to write a research paper or complete a certain task instead of taking a test.

Classes usually are organized through lectures. For example, a student may attend 2 or 3 lectures a week by the professor. As many as several hundred students sit at each lecture.

第2题

Although April did not bring the rains we all hoped for, and although the Central Valley

doesn’t generally experience the atmospheric (大气的) sound and lightning that can accompany those rains, it is still important for parents to be able to answer the youthful questions about thunder and lightning.

The reason that these that these two wonders of nature are so difficult for many adults to explain to children is that they are not very well understood by adults themselves. For example, did you know that the lighting we see flashing(闪烁) down to the earth from a cloud is actually flashing up to a cloud from the earth? Our eyes cheat us into thinking we see a downward motion when it’s actually the other way round. But then, if we believe only what we think we see, we’d still insist that the sun rises in the morning and sets at night.

Most lightning flashes take place inside a cloud, and only a relative few can be seen jumping between two clouds or between the earth and a cloud. But, with about 2,000 thunderstorms taking place above the earth every minute of the day and night, there’s enough activity to produce about 100 lightning strikes on the earth every second.

Parents can use thunder and lightning to help their children learn more about the world around them. When children understand that the light of the lightning flashes reaches their eyes almost at the same moment, but the sound of the thunder takes about 5 seconds to travel just one mile, they can begin to time the interval between the flash and the crash to learn how close they are to the actual spark.

26. According to the first paragraph, in the Central Valley area, rains come _____.

A. when it is April

B. when the field is dry

C. when people all hope for it

D. usually without thunder and lighting

27. We tend to think that lighting moves downward because_____.

A. our eyes play a joke on us

B. we take it to be true scientifically

C. we cannot see it clearly most of the time

D. it always runs down from a cloud to the earth

28. Which of the following is NOT true about lighting according to the passage?

A. Most lightning flashes take place inside a cloud.

B. About 2,000 thunderstorms occur above the earth every minute.

C. People can seldom see lightning flashes running between two clouds or between the earth and a cloud.

D. The thunderstorms happening above the earth can provide enough power to produce about 100 lightning strikes every second.

29. What does the word “ spark” in the last paragraph probably refer to ?

A. Cloud

B. Rain

C. Thunderstorm

D. Lightning flash

30. What does the passage imply?

A. Seeing is believing.

B. We should never trust what we see or hear.

C. People may easily make mistakes in their understanding of nature.

D. Children sometimes know more about nature than their parents do.

第3题

Question 21 to 25 are based on the following passage. Like fingerprints, no two faces

are exactly the same. Did you ever wonder how it is possible for us to recognize people? Even a skilled writer probably could not describe all the characters that make one face different from another. Yet a very young child---even an animal, such as a bird ------ can learn to recognize faces. We all take this ability for granted.

We also tell two people apart by how they behave. A person’s personality means the ways in which he acts, speaks, thinks and feels that make him different from others.

Like the human face, human personality is very complex. But describing a person’s personality in words is somewhat easier than describing his face, if you were asked to describe what a “nice face” looks like, you would have a difficult time doing so. But if you were asked to describe a “nice person”, you might begin to think about someone who is kind, thoughtful, warm, and so on.

There are many words that can be used to describe how a person thinks, feels, and acts. Gordon Allport, a U.S. scientist who studies the human mind, found nearly 18,000 English words characterizing differences in human behavior. And many of us use these words to describe different types of people ---- bookworms (书呆子), fools, workaholics(工作狂).

21. According to the passage, a very young child can _______.

A. learn to recognize faces

B. describe how a person thinks

C. learn to recognize fingerprints

D. describe what a “nice person” is like

22. According to the passage, we can tell two people apart by ________.

A. their behavior

B. their names

C. their hands

D. their clothes

23. Describing a “nice face” _________.

A. is quite easy

B. is a difficult task

C. is not as difficult as describing a “nice person”

D. may remind you of someone who was kind, thoughtful and friendly

24. It can be concluded from the passage that _________.

A. a “nice person” is very complex

B. it’s hard to describe a “nice person”

C. a “nice person” is considerate and kind

D. when we tell one person from another, we often refer to their face

25. Which of the following statements is NOT true about Gordon Allport?

A. He describes himself as a bookworm.

B. He does research on the human mind.

C. He found about 18,000 English words to describe human behavior.

D. The words he found are being used by many people to describe a person.

第5题

All of us can change our behaviour to fit different situations

.We are often noisy at weddings and sympathetic at funerals.Our table manners are not the same at a picnic as in a restaurant.When speaking with people,we feel free to interrupt close friends but tend to listen to our employers until they finish.If we don’t make such adjustments(调整),we are likely to get into trouble.

From one point of view,language is behaviour;it is part of the way we act.And like every other kind of behaviour,it must be adjusted to fit different contexts or situations where it is used.For instance,among people who are used to a writing system,there is one adjustment everyone makes:they speak one way and write another way.Speakers can stop in the middle of a conversation and repeat themselves if they sense that they are being misunderstood;writers often go back over their writing to see that it is clear,which is,however,before the communication occur.Once writers have passed their writing to someone else,they cannot change it.

Speakers can use intonation(语调)，stress(重音)，and pauses to help make their meaning clear.A simple sentence like “John kept my pencil” may mean,by a shift in the stress and intonation patterns,either John rather than someone else kept the pencil,or John kept rather than just borrowed the pencil,or it was a pencil rather than anything else that he kept.Writers,on the other hand,have their special tools of various punctuation(标点) marks,capitals,italic(斜体) letters,and so on.Skillful writers could also change the word order of a sentence.So“Cindy only had five dollars” could be turned into “Cindy had only five dollars” to mean Cindy had no more than five dollars,or into “Only Cindy had five dollars” to mean nobody but Cindy had five dollars.

36.The main purpose of the first paragraph in this passage is to _______.

A.summarize the passage

B.introduce the topic of the passage

C.use examples to illustrate the first sentence of the paragraph

D.use examples to illustrate the last sentence of the paragraph

A.we should appear happy at weddings and sad at funerals

C.our manners should be different in different places

D.our behavior. should be acceptable to others around

38.Language as mentioned in Paragraph 2 is considered _______.

A.a kind of behavior

B.an act found in all situations

C.an adjustment everyone makes

D.both spoken and written

39.According to Paragraph 2,speakers and writers differ mainly in _______.

A.the amount of time they spend on the communication

B.the number of times they stop while communicating

C.how they can make sure that they are not misunderstood

“There is no arguing about taste”—runs the Latin proverb. But taste did not just happen

. Cultural, historical, biological and environmental events have interacted to cause frogs, for example, to be viewed as delicious in southern China but to be regarded with revulsion(厌恶)in northern China. Even though much remains unknown, tastes cannot be dismissed as inarguable or illogical; an attempt will be made here to discover why, as Lucretius put it,“What is food to one man may be fierce poison to others?”

Among the approximately thirty million tribal people of India, a total of 250 animal species are avoided by one group or another. Most of these people will not eat meat from a tiger or any of various snakes. Although they say they feel a relationship with these animals, it is obvious that both are highly dangerous and that hunting them systematically would be foolish.

Monkeys are avoided, probably because they look like human beings in appearance; in these tribes, man-eating is viewed as extremely cruel. A reluctance to eat some female animals has been attributed to respect for the mother's role, but it could also be due to a policy of allowing the females to reproduce and provide more young for people .Many tribes avoid eating any animal that has died of unknown causes, an intelligent attitude in view of the possibility that the animal might have died from a disease that could spread to humans .Animals that consume garbage are similarly avoided, an adaptive step that prevents contact with parasites(寄生虫),and that might explain why members of one tribe eat any of twenty-one different species of rats ,but not the house rat.

31.“There is no arguing about taste”, which means .

A. people don't like to talk about food

B. one's taste in food is hard to explain

C. there is no quarrelling about what to eat

D. no arguments about taste have been heard of before

32.It can be concluded from the first paragraph that .

A. the author is against eating frogs

B. taste is illogical and inarguable

C. some types of frogs are poisonous

D. taste is influenced by many factors

33.The tribal people in India don't eat snakes because .

A. they ate very dangerous

B. they are respected by Indians

C. they may spread disease

D. they help kill rats

34.The tribal people in India may not eat the following animals EXCEPT .

A. donkeys B. tigers C. female deer D. house rats

35.The passage is probably written for the purpose of .

A. introducing the eating habit of Indian tribal people

B. distinguishing different types of taste

C. accounting for people's different choices of taste

D. explaining the relationship between taste and tribes

Prince was an intelligent dog and a slave to Williams. From morning till night

, when Williams was at home, Prince never left his sight. The dog had a number of clearly defined duties, for which Williams had patiently trained him and, like the good pupil he was, Prince lived for the chance to demonstrate his abilities. When Williams wanted to put on his boots, he would murmur“Boots”and within seconds the dog would drop them at his feet. At nine every morning Prince ran off to the general store in the village, returning shortly not only with Williams daily paper but also with a halfounce packet of Williams favorite tobacco. A gundog by breed, Prince possessed a large soft mouth specially evolved for the safe carrying of hunted creatures, so the paper and the tobacco came to no harm, never even showing a tooth mark.

Williams was a railway man, and he wore a blue uniform. that smelled of oil fuel. He had to work at odd times,“days,”“late days”or“nights.”Over the years Prince got to know these periods of work and rest, and knew when his master would leave the house and return. If Williams overslept, Prince barked at the bedroom door until he woke, much to the annoyance of the family.

A curious thing happened to Williams during the snow and ice of last winter. One evening he slipped and fell on the icy pavement somewhere between the village and his home. He was so badly shaken that he stayed in bed for three days; and not until he got up and dressed again did he discover that he had lost his wallet. The house was turned upside down in the search, but the wallet was not found. Two days later,Prince dropped the wallet into Williams hand. Very muddy, stained and wet through,the little case still contained fiftythree pounds, his driving license and a few other papers. No one could tell where the dog had found it.
