34、uate level classes are lectures and discussions. Participating in discussion is very important. Higher level classes involve very little lecturing. They emphasize discussion and presentation by the students.（分数：20.00）(1).According to the passage, good teachers should _.（分数：4.00）A.try to please their

35、 studentsB.understand their students wellC.treat their students as consumersD.make sure their students understand 解析：解析 本题为第一题，通常在文章开头寻找答案。第一段第四句表明，教师的职责是要确保学生能理解教学内容(make sure students understand)。而前一句话的内容解释了什么是不好的教师，可以判断这里形成对比，介绍的是好的教师是如何做的。因此 D 项为正确答案。 A 项中的 please students(取悦学生)没有在文章中出现。B 项的表述可以

36、查找到第一段最后一句，但注意该句的限定短语 in a sense(在某种意义上)，这只是在某种意义上的类比，并非实际情况。C 项混淆了动词 understand 的执行者和接受者。(2).Teachers are evaluated by students mainly on _.（分数：4.00）A.how well they perform in class B.how fluently they express themselves in classC.how carefully they prepare their lessonsD.how hard they work in and

37、after class解析：解析 根据题目中的 evaluated 定位到第二段。根据第二段最后一句可以知道学生评估教师的方面，such as 之后提到评估内容有解释是否清楚，准备是否充分，例子运用是否得当，解答问题是否清楚以及课堂组织效果如何等内容。总的来说，就是授课的好坏程度，即 A 项的表述。 B 项的干扰性最大，因为 B 项的内容在文章中出现过，但是教师的备课只是评估的一个方面，因此此选项不够全面。文章中没有提到 C 项和 D 项的内容，故排除。注意此题考查了考生总结概括句子大意的能力，切勿见到单个内容就匆忙答题。(3).What are students expected to do

38、 before attending a class?（分数：4.00）A.Go over the lessons thoroughly.B.Do the reading assignments.C.Understand the textbooks well. D.Prepare an outline for discussion.解析：解析 根据题目中的 before attending a class 定位到第三段第一句。该句提供了关于学生课前应该完成的任务的信息：read required textbooks and recommended books(阅读指定教材和推荐书目)，可见 C

39、项的表述是正确的。 A 项和 B 项的表述是文章中没有出现的，都是凭空捏造的干扰项。由于文章中介绍到授课方式有讨论(seminars 和 discussions)，根据常识似乎可以选择 D 项，但题目问的是 before class，而第三段已经说明了学生课前要阅读指定教材和推荐书目，因此 D 项也应该排除。(4).When a program starts, students should first _.（分数：4.00）A.learn how to do research and write papers B.learn about the course concretely and c

40、learlyC.have some learning experienceD.know how to participate in discussions解析：解析 根据题目中的 a program starts 定位到第三段第三句。题目中的 a program starts 对应该句的 at the beginning of the program，因此该句前面的 doing research and writing papers 为本题答案，可见 A 项的表述正确。 上下文没有谈及 learning experience 和 how to participate in discussion

41、s 的情况，可以排除 B 项和D 项。C 项有一定的干扰，因为其修饰语 concretely and clearly 在文章第三段中也出现过，但文中的内容是授课要求，而不是对学生的要求，解答题目时要把整个句子看清楚，不能仅因为选项中某些词在文中出现过就认为是正确答案。(5).Higher level classes are taught mainly through _.（分数：4.00）A.giving a lot of lectures to studentsB.asking students questions in class C.involving students in discu

42、ssionsD.answering students questions in class解析：解析 根据题目中的 Higher level classes 定位到最后一段倒数第二句。该句谈到，较高层次的课程中讲座的数量很少(involve very little lecturing)；最后一句则说，这种课程更强调学生之间的讨论和讲解(emphasize discussion and presentation)。B 项的表述与最后一句相同，为正确答案。 A 项的内容是倒数第二句中明确排除的，文中说到，较高等级的课程中讲座的数量很少。文章中没有提到asking students question

43、s 和 answering students questions 的情况，不选 C 项和 D 项。三、Task 2(总题数：1，分数：20.00)“But I just paid $1.69 for this bottle of wine last week. How come the price is now $2.25? What“s going on?“ There are at least three things going on that have caused the price of wine to rise. All have to do with the supply an

44、d demand factors of economics. The first factor is that people are drinking more wine than ever before. This demand for more wine has increased overall (总体) wine sales in America at the rate of 15 percent a year. The second factor is that the supply of wine has stayed relatively the same, which mean

45、s that the same number of bottles is produced each year. Wine producers are trying to open up new land to grow more grapes (葡萄).

The men who make wine are asking for more money, and the machinery needed to press the grapes is becoming

47、 more expensive. When the demand for something is greater than the supply, prices go up. When production costs, meaning the prices of labor and machinery, rise, the producer adds this increase to the price of the wine.（分数：20.00）(1).From the first paragraph, we know that the speaker is _.（分数：4.00）A.a

48、sking about the priceB.bargaining over the priceC.worrying about the priceD.complaining about the price 解析：解析 根据题目要求定位到第一段。说话人已经知道了价格，但对价格的上涨感到不满：How come the price is now.What“s going on?(为什么价格现在是搞什么啊?)D 项的 complain 意为“抱怨”，可见此选项符合题目要求。 说话的人已经知道了价格(从 1.69 上涨到 2.25)，故他不是在询问价格，排除 A 项。根据第一段说话人的语气，他是有点生

49、气的，想弄明白价格上涨是怎么回事，而不是对价格感到担忧，也没有与人讨价还价，排除 B 项和 C 项。(2).The three factors mentioned in the passage cause _.（分数：4.00）A.the sales of wine to increaseB.the production of wine to decrease C.the price of wine to go upD.more and more people to drink wine解析：解析 题目中提到的 three factors 分别出现在第二至五段。第二段是总起段，其中第一句谈到，至少有三个方面(three things)导致了葡萄酒的价格上升(the price of wine to rise)。这里的 three things 就是题目中的 three factors，B 项的 go up 与文中的 rise 同义，故为正确答案。 A 项仅仅是第一个因素带来的结果，不全面。C 项显然不对，因为第四段中提到葡萄酒的产量稳定(has
