Student participation (参与)in tike classroom is not only accepted but also expected of the student in many courses. Some professors base part of the final grade on the student’ s oral participation. Although there are formal lectures during which the student has a passive role(i. e. , listening and taking notes) , many courses are organized around classroom discussions, student questions, and informal lectures. In graduate discussions the profess or has a “manager”role and the students make presentations and lead discussions. The students do the actual teaching in these discussions.
A professor’ s teaching method is another factor (因素)that determines the degree and type of student participation. Some professors prefer to control discussion while others prefer to guide the class without controlling it. Many professors encourage students to question their ideas. Students who object to the professor’ s point of view should be prepared to prove their positions.
In the teaching of science and mathematics, the controlling mode of instruction is generally traditional, with teachers presenting formal lectures and students taking notes. However,new educational trends have turned up in the humanities and social sciences in the past twenty years. Students in education,society, and history classes, for example, are often required to solve problems in groups, design projects, make presentations, and examine case studies. Since some college or university courses are“practical” rather than theoretical，they pay more attention to “doing” for themselves.
“Participation in the classroom is not only accepted but also expected of the student” in many courses except in____.
A.science and mathematics
B.the humanities and social sciences
C.informal lecture courses
D.discussion courses
From the passage we know that education in the humanities and society____.A.has not changed much
B.pay attention to students’ studying instead of teachers’ teaching
C.is much more important than that of science and mathematics
D.has become more practical than theoretical
The reason why some professors ask students to make presentations and lead discussions is that____.
A.these professors are often not well prepared before class
B.these professors want to stress “doing”
C.these professors want to test the students’ abilities
D.these professors are not willing to teach theory
Which of the following sentences is true according to the passage？A.Student participation is not common in the classroom in many courses like society.
B.Some professors want to control the classroom discussion.
C.Some professors usually want the students to take part in the teaching of science and mathematics.
D.New educational trends have turned up in teaching of natural sciences such as chemistry.

第4题
In my family it was always important to place blame when anything bad happened. But the Whites didn't worry about who had done what. Mr. and Mrs. White had six children: three sons and three daughters.
In July, the White sisters and I decided to take a car trip to New York. The two oldest, Sarah and Jane, were college students, and the youngest, Amy had recently got a driver' s license, and was excited about practicing her driving on the trip.
The big sisters let Amy take over. She came to an intersection with a stop sign, but Amy continued without stopping. The driver of a large truck, crashed into our car.
Jane was killed instantly.
When Mr. and Mrs. White arrived at the hospital, they hugged us all.
To both of their daughters, and especially to Amy, over and over they simply said, "We' re so glad that you're alive."
I was astonished. No blame.
Later, I asked the Whites why they never talked about the fact that Amy was driving and had run a stop sign.
Mrs. White said, "Jane's gone, and nothing we say or do will bring her back. But Amy has her whole life ahead of her. How can she lead a full and happy life if she feels we blame her for her sister' s death？"
They were right. Amy graduated from college and got married several years ago, She works as a teacher of learning-disabled students. She' s also a mother of two little girls of her own, the oldest named Jane.
The writer of the article is ______ .
A．Mrs. White's niece
B．the Whites' cousin
C．Sarah' s friend at college
D．Jane' s friend at school

？？？？Questions 11 to 15 are based on the following passage:
Apopularly-held view has it that “opportunity to learn” is the key to educational success -i.e.the more time children spend on a subject, the better they do at it. According to the recent study there seems little correlation between time spent on a subject and performance of pupils in tests. Young Austrians spend exceptionally long hours on math and science lessons; for them it pays off in higher test scores. But so do New Zealand&39;s teenagers and they do not do any better than, say Norwegians, who spend an unusually short time on lessons in both subjects. Next and of particular interest to cash-strapped governments there appears to be little evidence to support the argument, often heard from teachers&39; unions, that the main cause of educational under achievement is under funding. Low-spending countries such as South Korea and the Czech Republic are at the top. High-spenders such as America and Denmark do much worse. Obviously there are dozens of reasons other than spending why one country does well, another badly, but the success of the low–spending Czechs and Koreans does show that spending more on schools is not aprerequisite（前提） for improving standards.
Another article of faith among the teaching profession that children are bound to do better in small classes is also being undermined by educational research. The study found that France, America and Britain, where children are usually taught in classes of twenty-odd, do significant1y worse than East Asian countries where almost twice as many pupils are crammed into each class. Again, there may be social reason why some countries can cope better with large classes than others. All the same, the comparis on refutes the argument that larger is necessarily worse, Further, the study even cast some doubt over the cultural explanation for the greater success o fEast Asia: that there is some hard-to-define Asian culture, connected with parental authority and a strong social value on education, which makes children more eager to learn and easier to teach. Those who make this argument say it would of course be impossible to replicate such oriental magic in the West.
Yet the results of the study suggest that this is, to put it mildly, exaggerated. If “culture” makes English children so poor at math, then why have they done so well at science (not far behind the Japanese and South Koreans)？Any why do English pupils do well at science and badly at math, while in France it is the other way around ？A less mystical, more mundane explanation suggests it self English school: teach science well and math badly; French schools teach math better than science; East Asia schools teach both subjects well.
The passage is mainly concerned with ___.？？
？？A.establishing a relationship between culture and education
B.exposing educational myths
C.introduction educational philosophies
D.comparing education philosophies
All of the following are common-held beliefs about education EXCEPT___.
A.time spent on a subject correlates with academic success
B.educational achievements correlate with the money spent
C.large classes contribute to poor educational achievement
D.culture is not a deciding factor in school performance
Which of the following statements is supported by the passage？
A.Austrian teenagers do better than New Zealands teenagers
B.Low-spending will lead to good school performance.
C.Students in large classes will do better than students in small class.
D.Asian culture makes students eager to learn and easy to teach.
The fact that English pupils do well at science and badly at math while in France it is the other way around is attributable to ___.A.cultural values
B.teaching methods
C.class size
D.money spent
Which of the following countries does worse in science？A.Japan.

D.France
