问题是：

　　The students discuss two possible solutions to the man’s problem. Describe the problem. Then state which of the two solutions you prefer and explain why.

　　6.Lecture in a science and technology class: the female professor is talking about that in the long long human history, inventions and innovations always happen in one of the two ways: intentionally and accidentally.

　　First, she quotes an example of intentional innovation: bi-focus glasses. Before the bi-focus glasses were invented, people had to carry two pairs of glasses sometimes and this was very inconvenient. Thus, bi-focus glasses were intentionally invented to solve this problem.

　　Second, she takes another example of accidental innovation: the discovery of X-ray. When people first encountered X-ray in the lab, they had no idea of what this discovery meant, or where to put this discovery into application.

　　问题是：

　　Using points and examples from the talk, explain the two ways of innovation presented by the professor.

　　点评：复合类题型的解题关键在于作笔记。然后结合笔记进行复述。只要能把关键要点摘出，并把要点插入我们课堂上总结的针对每道题特点给出的摸板，就能达到很理想的分数。所谓“口语很烂，但是口语分数很高”在有考官的雅思口试中基本是不可能的，但是在题目类型固定，特点明确且考官缺位的托福考试中是极为可能的。提示：多用简单短句！只求清晰复述材料内容即可。

　　作文部分

　　共有两题。第一题是一道independent writing task. 先有一篇四段的文章，3分钟阅读时间。文章提纲如下：1. chimpanzees has similar ability of human being in learning language.

　　2. chimps 可以掌握 vocabulary

　　1.Chimps’ learning ability is by no means close to that of human beings.

　　2.Chimps can only pick up a few Yerkish words after researchers’ intentional repeating. While human children can learn more than one language by simply listening.

　　3.Chimps only know to put a few words together and this can not be called “grammar”.

　　4.The so called “conversation” is normally dominated by the researchers by keeping asking questions, while chimps only do the responding part.

　　问题是：summarize the points made in the lecture, being sure to specifically explain how they cast doubt on points made in the reading passage.

　　最后是一道independent writing task.
