题目内容
20.-Mr Li,let's go fishing if it is fine this weekend,shall we?-I'd love to.But nobody knows if it _______.( )
| A. | is raining | B. | rains | C. | will rain | D. | has rained |
分析 李先生,如果这周末天气好,我们就去钓鱼吧,好吗?
我非常乐意去钓鱼,但是没人知道是否会下雨.
解答 答案为C.第二句子中if表示如果,if在这里引导一个宾语从句,if的用法是在复合句中主句用一般现在时,则if引导的宾语从句可以根据句子的需要选用任何一种时态.句子的主句是nobody knows,主句用的是一般现在时态,则if引导的从句根据时间状语this weekend题得知要用一般将来时,一般将来时态是要用will+动词原形,故will+rain符合题意,故答案为C.
点评 这一题主要判断句子中if表示什么意思,并且判断if是否引导一个条件状语从句,然后就可以得知答案.
