题目内容
13.We will have a picnic if it _____ tomorrow.( )| A. | won't rain | B. | didn't rain | C. | doesn't rain | D. | isn't raining |
分析 如果明天不下雨我们就去野餐.
解答 答案:C
本句考查if引导的条件状语从句,在含有条件状语从句中的复合句中,如果主句中用一般将来时,从句使用一般现在时表将来.一般现在时的构成是:主语+动词原形/动词的第三人称单数形式;且从句中主语it 是第三人称单数形式,再根据句意"如果明天不下雨我们就去野餐."应该是doesn't rain.故选C.
点评 做本题的关键是正确判断从句的类型,并熟练掌握对宾语从句和状语从句中时态方面的要求.
