18.I have no idea if it ________ tomorrow.If it _________,I ________ go swimming.( )| A. | rains,rains,don't | B. | will rain,will rain,won't | ||
| C. | rains,will rain,can't | D. | will rain,rains,won't |
分析 我不知道明天是否下雨,如果下雨,我就不会去游泳,
解答 答案:D.第一个if引导的是宾语从句,主句是一般现在时,从句时态不受限制,结合tomorrow用一般将来时will+动词原形,第二个if引导的是条件状语从句,遵循主将从现的规则,从句主语it,故rains,故选D.
点评 if 一条件状语从句,译为"如果".He will come if you invite him.如果你请他,他会来的.
二是宾语从句,译为"是否".I wonder if she is ill.不知她是否病了.
三是引导非真实条件句,使用虚拟语气,译为"假如,要是"
If I were you,I would never do that.
如果我是你,我决不做那件事.
