13.I'm waiting for Jack ________,I will go swimming alone.( )| A. | If he doesn't come | B. | If he won't come | ||
| C. | If he will come | D. | If he is coming |
分析 我在等Jack,如果他不来,我就一个人去游泳.
解答 答案:A.
据语境可知复合句的意思是"如果他不来,我就一个人去游泳.",句子中if的意思为"如果"引导条件状语从句,在时态上,遵循"主将从现"的原则,即:主句用一般将来时,if从句用一般现在时表示将来.从句中,主语是Jack,变否定句借助于助动词does.故答案为A
点评 明确句意掌握if引导条件状语从句时的用法是做词类题的关键,if引导条件状语从句时,时态遵循"主将从现"的原则,即:主句用一般将来时,if从句用一般现在时表示将来.
