题目内容
19.I don't know if she ____________ if it _____________ tomorrow.( )| A. | comes,snows | B. | will come,will snow | ||
| C. | comes,will snow | D. | will come,snows |
分析 如果明天下雪,我不知道她是否会来.
解答 答案:D 本题考查时态辨析.本题考查的是if 引导的宾语从句或条件状语从句,在引导宾语从句时,从句的时态根据自己的需要决定,第一个空后面在if 引导的宾语从句时,根据后面的tomorrow可知要用一般将来时,构成 是will do,而if引导的条件状语状语从句,时态是主将从现原则,所以第二个空是一般现在时,主语it是第三人称单数,故后面的动词snow要第三人称单数形式snows,故选D.
点评 本题考查时态辨析.做此题目可根据句中的时间状语或句中的动词形式.也可根据语境,判断时态,从而选出正确的形式完成此类题.
