(二)

Professor: Through much of the last century, America’s faith in freedom and democracy was a rock in a raging sea. Now it is a seed upon the wind, taking root in many nations.

Narrator: Listen again to part of the lecture. Then answer the question.

Professor: … Now it is a seed upon the wind, taking root in many nations.

What is the professor mainly about?

A: To encourage the students to think about the issue under a bigger context.

B: To elicit an answer from the students.

C: To compare two different things figuratively to engage his students.

D: To describe an imaginative situation.

分析：

1、从教授的谈话中, 可以看出教授使用的是暗喻的方法。

2、段落大致的意思是：在上个世纪的大部分时间里，美国式民主和自由的信仰如石沉大海，波澜不惊；而今，却如清风拂絮，撒落人间。可见，暗喻的方式是为了形成对比，从而激起听者的想象力，活跃课堂谈话的气氛。

3、综合上下文，答案C 为正确答案。

总之，在做IBT听力主旨题的时候, 要把握住重点。排除过于笼统的答案，所表示的内容与谈话或演讲的核心主题脱节；和过于精确的答案，即据之一而非讲述主体。还要切记排除一些似是而非的答案和在上下文中并未被谈话人提及的答案。把握住这些要领，相信攻克IBT听力主旨题不再是一件难事。
