题目内容
1.He told us whether _____ a picnic was still under discussion.( )A. | to have | B. | having | C. | have | D. | had |
分析 他告诉我们是否野餐还在讨论中.
解答 答案是A.本题考查动词不定式做主语.分析句子的结构可知本题是whether之前省略that的宾语从句,在宾语从句中缺少的是主语;谓语动词不能做主语,所以排除C和D;英语中可以用"连接词+to do"相当于名词性从句,本题中whether to have a picnic 相当于主语从句"whether we will have a picnic",动名词没有此用法,所以答案选择A.
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.
