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: Why not?
M: They said that my lack of knowledge in higher mathematics might be an obstacle in understanding Professor Smith's theory.
W: Really?
M: (I ) Jack tqld me that Professor Smith usually uses lots of formulas inside class. So you'd better make sure that you are extremely familiar with these formulas if you are seriously considering taking his course.
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
