例题8.

Which of the following does paper burn in?

A. CO2 B. N2 C. O2 D. He

例题9.

Today, the forests have almost gone. People must down too many trees.

A. stop to cut B. stop from cutting C. be stopped to cut D. be stopped from cutting

【解析】选D。本题考查被动语态的用法。最具迷惑性的选项是A，不少同学们只记得stop之后可接动词不定式，殊不知这时不定式作目的状语，因此，我们应透过现象看本质，排除A；那么，本题的真正意义是什么呢？“当今，森林几乎没了，必须要阻止人们砍伐太多的树木。”这样，我们不难已起stop sb. from doing sth. 这个习语，本题使用的是被动形式。

例题10.

--- You must come back every month.

--- Yes, I _____.

A. will B. must C. should D. can

【解析】选A。本题考查情态动词的用法。选项B有较大的干扰性，不少同学们仅从对话上文的must支猜测、推断，却不知这种回答显得呆板、没有交际意义；与must相比，I will表示一种意愿色彩，更适合作为上文的答语。
