题目内容
11.__________ the experiment right,I tried again and succeeded.( )A. | Not having done | B. | Having not done | C. | Not doing | D. | Not done |
分析 因为没有正确地做这个实验,于是我再试了一次,结果成功了.
解答 答案:A 根据句意,没有正确做实验这个动作是发生在我再试一次之前,且是再试一次的原因,所以非谓语动词要用现在分词的完成式having done,又非谓语动词的否定形式是直接在其前面加否定词not,所以空白处要用Not having done,Not having done the experiment righ在句中做原因状语,故选A.
点评 本题考查否定句和现在分词的完成式.考生在解题时要理清动作之间的先后关系,并掌握非谓语动词的否定形式中not的位置,就可以选出答案.
