Many visitors finds the fast pace at which American people move very troubling. One's first impression is likely to be that everyone is in a rush. City people always appear to be hurrying to get where they are going and are very impatient if they are delayed even for a short moment.
At first, this may seem unfriendly to you. People will push past you as they walk along the street. You will miss smiles, brief conversations with people as you shop or dine away from home. Do not think that because Americans are in such a hurry they are unfriendly. Often, life is much slower outside the big cities, as is true in other countries as well.
Americans who live in cities often think that everyone is equally in a hurry to get things done; just as city people do in Tokyo, Singapore or Paris, for example. But When they discover that you are a stranger, most Americans become quite kindly and will take great care to help you. If you need help and say, "I am a stranger here. Can you help me？' Most people will stop, smile at you, and help you find you way or answer your questions. Occasionally, you may find someone too busy or perhaps too rushed to give you help. If this happens, do not be discouraged (气馁); just ask someone else. Most Americans enjoy helping a stranger.

A、America is a highly developed country
B、Americans are impatient and unfriendly people
C、the fast pace in American life often causes much trouble

第9题
Questions 21 to 25 are based on the following passage:
A scientist who does research in economic psychology and who wants to predict the way in which consumers will spend their money must study consumer behavior. He must obtain data both on resources of consumers and on the motives that tend to encourage or discourage money spending.
If an economist as asked which of three groups borrow most—people with rising incomes, stable incomes, or declining incomes—he would probably answer:those with declining incomes. Actually, in the years 1947—1950, the answer was: people with rising incomes. People with declining incomes were next and people with stable incomes borrowed the least. This shows us that traditional assumptions about earning and spending are not always reliable. Another traditional assumption is that if people who have money expect prices to go up, they will hasten to buy. If they expect prices to go down, they will postpone buying. But research surveys have shown that this is not always true. The expectations of price increase may not stimulate buying. One typical attitude was expressed by the wife of a mechanic in an interview at a time of rising prices. “In a few months,” she said, “we’ll have to pay more for meat and milk; we’ll have less to spend on other things.” Her family had been planning to buy a new car but they postponed this purchase. Furthermore, the rise in prices that has already taken place may be resented and buyer’s resistance may be evoked.
The investigations mentioned above were carried out in America. Investigations conducted at the same time in Great Britain, however, yielded results that were more in agreement with traditional assumptions about saving and spending patterns. The condition most conductive to spending appears to be price stability. If prices have been stable and people consider that they are reasonable, they are likely to buy. Thus, it appears that the common business policy of maintaining stable prices is based on a correct understanding of consumer psychology.
21.If a scientist wants to study consumer behavior, what must he do？
A) He must predict the way in which consumers will spend their money.
B) He must do scientific research.
C) He must know background of customers.
D) He must do research and learn the resources and motives of customers.
22.Which of the following groups borrow money most according to traditional assumption？
A) People with rising incomes.
B) People with stable incomes.
C) People with declining incomes.
D) None of the above.
23.Which of the following statements is NOT true according to the passage？
A) Traditional assumptions about earning and spending are not always reliable.
B) The condition that most helps to produce spending appears to be price rising.
C) Maintaining stable prices is a common business policy.
D) The results of the investigation in America were not the same as those in Great Britain.
24.The research survey in America have showed that when the prices rise, ____.
A) people will hasten to buy
B) people will stop buying
C) people will postpone their purchase
D) people will buy more than they can use
25.The saving and spending patterns in America are ____ those at the same time in Britain.
A) different from B) much better than C) the same as D) much worse than

第11题
People will be alert(警觉的)and receptive if they are faced with information that gets them to think about things they are interested in. And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.
Many experts are so convinced of the benefits of challenging in the brain that they are putting the theory to work in their own lives. “The idea is not necessarily to learn to memorize large amounts of information,” says James Fozard, associate director of the National Institute of Ageing. “Most of us don’t need that kind of skill. Such specific training is of less interest than being able to maintain mental alertness.” Fozard and others say they challenge their brains with different mental skills, both because they enjoy them and because they are sure that their range of activities will help the way their brains work.
Gene Cohen, acting director of the same institute, suggests that people in their old age should engage in mental and physical activities individually as well as in groups. Cohen says that we are frequently advised to keep physically active as we age, but older people need to keep mentally active as well. Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted. “The point is, you need to do both,” Cohen says. Intellectual activity actually influences brain-cell health and size.
(1)What is the passage mainly about?()
A. Special mental training for old people.
B. Biochemical changes in the human brain.
C. The influence of intellectual activities on brain-cell size.
D. The importance of mental activities in the efficiency of the brain.
(2)A person who is said to be cognitively healthy should ().
A. be alert and receptive in mind B. who are highly intelligent
C. be good at doing group work D. remember large quantities of information
(3) The findings of James and other scientists in their work ().
A. remain a theory to be further proved B. have been challenged by many other experts
C. are practiced by the researchers themselves D. have been generally accepted
(4)According to Fozard's argument, people can make their brains work more efficiently by ().
A. constantly doing memory work B. making frequent adjustments
C. going through specific training D. taking part in various mental activities
(5) Which of the following statements would Cohen most probably support?()
A. Older people should keep mentally active by challenging their brains.
B. No matter whether it is done in group or alone, mental activity is always good for brain-cell health.
C. Physical strength is more important to older people than mental health.
D. People who engage in more mental activities but less physical ones are always happier.
