PART I DICTATION

What We Know About Language

Many things about language are a mystery and will remain so. / However, we now do know something about it. / First, we know that all human beings have a language of some sort. / No human race anywhere on earth is so backward / that it has no language of its own at all. /Second, there is no such thing as a primitive language. / There are many people whose cultures are undeveloped, / but the languages they speak are by no means primitive. / In all the languages existing in the world today,/ there are complexities that must have been developed for years. / Third, we know that all languages are perfectly adequate./ Each is a perfect means of expressing its culture. /And finally, we know that language changes over time, / which is natural and normal if a language is to survive. / The language which remains unchanged is nothing but dead.

SECTION A CONVERSATIONS

Questions 1 to 3 are based on the following conversation.

M:Jill,have you registered with the next semester?

W:Not yet, there's still something that I'm not sure. Do you know if Professor Smith's economics 102 is still available to all undergraduate students?

M: No, I don't think so. Last semester I tried to register in that course but all the other people told me not to.

W:What a shame I (2)My friends all told me that Professor Smith has lots of original ideas and he really can stimulate students to think. But I don't think I have the mathematical skills to keep up with the others.

M:lf you want to take the course so much, why don't you register in a course in higher mathematics first?

W. But I'm afraid that I will miss Professor Smith's course when I finish the mathematics course. M: Hey, I heard that Professor Smith would give the same course in the semester that starts next fall. ( 3 ) Why don't you take a year's higher mathematics and register in economics 102 the next fall?

W:That sounds a good idea.

I. [ B] 推断题。根据''They said that my lack of knowledge in higher mathematics might be an obstacle in understanding Professor Smith's theory.可知，缺少高等数学知识会阻碍理解史密斯教授的理论，所以学习经济学需要有高等数学知识，因而[ B]项伟正确答案。

2. [D] 细节题。文中提到''My friends all told me that Professor Smith has lots of original ideas and he really stimulate students to think.”由此可知，史密斯教授有很很多新颖的观点，斌且
