4.We are not sure if it tomorrow.If it ,our sports meeting will be put off.( )| A. | rains; rains | B. | rains; will rain | ||
| C. | will rain; will rain | D. | will rain; rains |
分析 我不确信,明天是否下雨,如果明天下雨,我们的运动会将会推迟.
解答 答案:D.根据We are not sure if it tomorrow.If it ,our sports meeting will be put off我不确信,是否明天是否下雨,如果明天下雨,我们的运动会将会推迟;可知有两个if,第一个if是"是否"的意思,引导的是宾语从句,根据宾语从句的时态,可知因为tomorrow,应该用将来时will rain;第二个if是"如果"的意思,其时态应该是"主将从现",即主句用将来时,从句应该用一般现在时;故选D.
点评 以if引导的从句有两个,一个是宾语从句,一个是条件状语从句.做题时应该首先明确它引导的是什么从句,然后根据它的时态用法,来确定选项.
