第3题

Questions 31 to 35 are based on the following passage:

When I was studying at Yale, some phenomena puzzled me greatly. I found that Chinese students or Asian students were very polite in class while American students often interrupted the professor, asking questions and dominating the discussion. The Chinese students were not as aggressive as American students.

I was impressed by the role of the professor in the seminar(讨论会). The professor didn’t act as an authority, giving final conclusions, but as a reseac her looking for answers to questions together with the students. One lingui stic(语言的) feature of his interacting with his students was that he used many modal(情态的) verbs—far more than I did in Beiwai. When answering questions, he usually said, “This is my personal opinion and it could be wrong.” or “You could be right, but you might find this point of view also interesting.”

In China, authorities are always supposed to give wise decisions and correct di rections. Therefore, students always expect the professor to give an answer to th e question. I still remember how frustrated they were when foreign teachers did not provide such an answer. Their expectations from authorities are much higher than that of American students. Once the Chinese students got the answer, they w ere sure about it.

Education in China is valued for united thinking. I remember American teachers who taught in our university complaining about the fact that Chinese students u niformly expressed the same idea in their English composition. The examinations in America usually do not test a student’s ability to memorize the material but his ability to analyze and solve problems. Education in America is valued not on ly as a means to obtain employment but as a process of enhancing critical thinking.

31.In the USA, when the students are in class, ____.

A.a Chinese student tends to be very active

B.an American student likes to make trouble

C.a Chinese student likes to puzzle the teacher

D.an American student tends to be vigorous

32.A teacher in the USA prefers to ____ when he answers questions.

A.be very sincere B.be very direct

C.be very self confident D.be very indifferent

33.What is the opinion of the author concerning the difference of teachin g methods between China and the USA？

A.He thinks that Chinese teaching metods can make students learn more.

B.He holds that the major purpose of Chinese teaching methods is to impro ve students’ remembrance.

C.He thinks that American teaching is ability oriented.

D.He holds that American teachers hate to give a test.

34.The author thinks that the relationship between the student and the te acher is ____.

A.more intimate in China B.closer in China

C.looser in USA D.more harmonious in USA

35.The education in USA may produce some ____ graduates.

A.talkative B.conventional C.creative D.imaginative

The Family Then and Now

Things were never easy within the family. But at a time

when the family was oriented toward the production of goods,

which alone made the survival of its members possible there

was an obvious necessity and a rational base for their living 【M1】______

and working together. Dire necessity did not permit putting into

question the very existence of the family, despite of the great 【M2】______

emotional demands living together made to each of its 【M3】______

members.

Today the main economic activities of the family are in

the nature of consumption—how productive may be what some 【M4】______

of its members do in society. And from an early age on, each

member of the family could survive without its support—since

society at large is ready to provide support. Also, it is quite 【M5】______

easy to put the existence of the family into question. This

happens very frequent, not just as families separate or fail to be 【M6】______

formed, but also within families which in all outer appearance 【M7】______

are still intact. But once the family needs seriously to justify its

existence, it is no longer intact like a family in the old sense. 【M8】______

The modern family, deprived of its ancient and firm basis

in economic need, now tries to justify its existence through the 【M9】______

emotional ties within it. These always were present,

but they were a superstructure, good or bad, over the solid

foundation of necessity. With the foundation of necessity

moved, the emotions either tend to run rampant or to wither 【M10】______

away.

The more a family tries to justify itself by means of the

feelings existing within it, the stronger these are aroused, and

the more easily and severely do they get hurt.

【M1】

Passage Two Questions 6 to 10 are based on the following passage. On Jan. 9, 2007, Steve Jobs formally announced Apple’s “revolutionary mobile phone” — a device that combined the functionality of an iPod, phone and Internet communication into a single unit, navigated by touch. It was a huge milestone in the development of smartphones, which are now owned by a majority of American adults and are increasingly common across the globe. As smartphones have multiplied, so have questions about their impact on how we live and how we work. Often the advantages of convenient, mobile technology are both obvious and taken for granted, leaving more subtle topics for concerned discussion: Are smartphones disturbing children’s sleep? Is an inability to get away from work having a negative impact on health? And what are the implications for privacy? But today, on the 10th anniversary of the iPhone, let’s take a moment to consider a less obvious advantage: the potential for smartphone technology to revolutionize behavioral science. That’s because, for the first time in human history, a large proportion of the species is in continuous contact with technology that can record key features of an individual’s behavior and environment. Researchers have already begun to use smartphones in social scientific research, either to query people regularly as they engage in their normal lives or to record activity using the device’s built-in sensors. These studies are confirming, challenging and extending what’s been found using more traditional approaches, in which people report how they behaved in real life or participate in relatively short and artificial laboratory-based tasks. Such studies are just first steps. As more data are collected and methods for analysis improve, researchers will be in a better position to identify how different experiences, behaviors and environments relate to each other and evolve over time, with the potential to improve people’s productivity and wellbeing in a variety of domains. Beyond revealing population-wide patterns, the right combination of data and analysis can also help individuals identify unique characteristics of their own behavior, including conditions that could indicate the need for some form of intervention — such as an unusual increase in behaviors that signal a period of depression. Smartphone-based data collection comes at an appropriate time in the evolution of psychological science. Today, the field is in transition, moving away from a focus on laboratory studies with undergraduate participants towards more complex, real-world situations studied with more diverse groups of people. Smartphones offer new tools for achieving these ambitions, providing rich data about everyday behaviors in a variety of contexts. So here’s another way in which smartphones might transform the way we live and work: by offering insights into human psychology and behavior and, thus, supporting smarter social science. 10. What do we learn about current psychological studies?

A、They are going through a period of painful transition.

B、They are increasingly focused on real-life situations.

C、They are conducted in a more rigorous manner.

D、They are mainly targeted towards undergraduates.
