题目内容
7.-I wonder if there ________ a class meeting this week.-If there ________,I will tell you at once.( )
| A. | will be;is | B. | would be;have | C. | is;will be | D. | will be;will be |
分析 --我想知道本周是否开班会.
--如果开的话,我会立刻告诉你的.
解答 答案:A.根据I wonder if there 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this week可知,动作还没有发生,所以用一般将来时态,含有there be句型的一般将来时表达为there will be;又根据If there ________,I will tell you at once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",故选A.
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.
