题目内容
10.We don't allow ________ in the office.But you are allowed ________ in the rest room.( )A. | smoking; smoking | B. | to smoke; to smoke | ||
C. | smoking; to smoke | D. | smoke; smoking |
分析 我们不允许在办公室吸烟,但是你可以在休息室吸烟.
解答 答案是C.本题考查动词allow后接宾语和宾语补足语的用法.allow后面直接接动名词做宾语,所以第一空用动名词,排除B和D;allow后接动词不定式做宾语补足语,即allow sb.to do sth.,它的被动结构是sb.be allowed to do,所以第二空用to smoke,答案选择C.
点评 对于非谓语动词的选择,首先要根据句子的结构判断句中缺少的是谓语动词还是非谓语动词;如果是非谓语动词,在理解非谓语动词的基本用法的基础上再根据句子的结构做出判断.动名词是在句中起着名词的作用,往往在句中做主语、宾语和定语.在动名词的考查中特别关注介词、一些动词和形容词后接动名词做宾语的结构.
