听力原文： On Feb 15th, 1989, an instant survey was carried out among 18 overseas postgraduate students. Eleven students were male and seven were female. The purpose of the survey was to discover the views of the students on a number of matters of personal concern. The survey was conducted by means of a questionnaire given to the students to complete. There were five questions. The first question concerned favorite color and the .second favorite number. The next 3 questions were all concerned with aspects of marriage. No. 3 looked at the ideal age to get married, No. 4 examined the qualities looked for in a partner and No. 5 asked about the ideal number of children. The main findings were as follows: Blue was the most popular color. This was followed by Green and Purple. There was no real significance in the choice of lucky numbers. About one third of the students said that they had none. Sixty-one percent of the students selected the age group 26 to 30 years as ideal for marriage, followed by 21 to 25 years. In looking for the most important qualities in an ideal partner, someone hoped the person to be Intelligent, others chose Natural, and still others indicated Attractive and Honest. The ideal number of children was 2, followed by 3. It is not easy to reach any definite conclusions based upon such a small sample of students from such widely different backgrounds. However, it is clear that majority favorite of 26 to 30 is the ideal age to get married with an intelligent partner, thereby producing 2 children.

In a big university there may be several thousand students taking a compulsory course at the same time. There are various ways of dealing with such a course: we may take as an illustration a sociology course, with say 3,000 students. The students would be divided into about eighty separate classes, each meeting three times a week. There might be a single textbook provided for all the students following the course; or, instead of an ordinary textbook, a specially printed course-book prepared by a committee of the teachers. In preparation for each meeting of the class the teacher might ask the students to read five or ten pages, in order to discuss them and thus find out how well the students had done their work. This is only an example of one method followed: some universities make use of closed-circuit television techniques, including two-way devices, which enable students to put questions to a lecturer in another room. A Maximum of discussion, rather than formal teaching, is widely accepted as an ideal to be aimed at, even amid the difficulties imposed by the great numbers of students involved.
What's a student in his second year called.？
A．Senior.
B．Sophomore.
C．Freshman.

Part science and part natural history, ornithology(鸟类学) owes its tremendous popularity as a science and a scientific recreation to a simple circumstance that is sometimes forgotten when we weigh the eligibility(有被选资格，合适)of different kinds of animals for informal study. Birds are day animals where others, just as engaging in their way—mice, for instance—are creatures of the night. Apart from their visibility (something very much in their favor), the beauty of birds and their many appealing habits have won for them a huge fan following that has more than once tempted impatient and ill-informed laboratory biologists to dismiss ornithology as so much bird-watching—an absurdly unjust judgment that ignores the fact that ornithology has made a number of profoundly important contributions to general biology.
Professional biologists are not hard put to reel off(滔滔不绝地讲) a list of distinctive contributions that ornithology has made to general biology science. They will cite, for example, Ernst Mayr's investigations of evolution and the mechanisms of speciation (物种形成), or M. R. Irwin's work on the immunologic performance of species of Columbidae(pigeons and doves) and of hybrids(杂交种)between them. Then again, David Lack's studies on mortality in wild populations of birds are the most illuminating life tables of wild animals and animal demography (统计学) generally. Most important of all, perhaps is the contribution that ornithology has made to the study of animal behavior, beginning with Julian Huxley' s classic study of the courtship habits of the great crested great and followed by Niko Tinbergen's studies on the behavior. of herring gulls.
What is the main idea of the passage？
A．Birds are widely studied because they are popular in the home.
B．Ornithology has made important contributions to biology.
C．Professional biologists often engage in bird-watching for recreation.
D．Animal behavior. is best studied by observing birds.

Piaget has only been widely known in this country since the 1960s, when his works were translated from their original French. But he has been recognized as an expert in the field of cognitive development in Europe since the 1930s. In fact, Piaget's publishing career can be traced to the year 1906, when as a child of ten, he published his careful notes on the habits of an albino sparrow he observed near his home in Switzerland. After his precocious debut as an ornithologist, he took an after school job at the local natural history museum, soon becoming an expert on mollusks. At the age of sixteen he was recommended for a curator's position at the natural history museum in Geneva, but declined in favor of continuing his education.
He studied natural science at the University of Neuchatel, obtaining his doctorate at the age of twenty-one. His readings in philosophy stimulated an intense interest in epistemology-the study of humans acquire knowledge. Convinced that cognitive development had a genetic basis. Piaget decided that the best way to approach epistemology would be through its behavioral and biological components. Psychology appeared to be the discipline that best incorporated this approach.
According to the passage, Piaget went to the mountains every summer to
A．collect data for his research.
B．avoid the city heat and enjoy the cool weather.
C．live in his cabin where he could analyze the data he collected there.
D．analyze his research data he had collected before.
