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。 |
