题目内容
2.-Mum,I don't know if Honghong to my party tomorrow.-I think she will come if she free.( )
| A. | comes,is | B. | comes,will be | ||
| C. | will come,is | D. | will come,will be |
分析 --妈妈,我不知道红红明天是否要来参加我的聚会.
--我想如果她有空就会来的.
解答 答案:C 根据I don't know if Honghong to my party tomorrow可知,if在动词后面,它引导的是宾语从句,表示"是否".当主句是一般现在时态或含情态动词的句子,宾语从句应该根据需要选用任何时态.此句由tomorrow可知,动作还没有发生,所以用一般将来时态,排除AB;又根据she will come if she free可知,if引导的是条件状语从句,当主句是一般将来时态,从句应该用一般现在时态表将来,我们称这一现象为"主将从现",排除D.故选C.
点评 本题考查宾语从句和状语从句,if引导的是条件状语从句,当主句是一般将来时态,从句应该用一般现在时态;if引导的是宾语从句,当主句是一般现在时态或含情态动词的句子,宾语从句应该根据需要选用任何时态.
