题目内容
16.I'm not sure if he _______in this exam.But if he _____harder,he will do better.( )| A. | succeeds; works | B. | will succeed; will work | ||
| C. | will succeed; works | D. | succeeds; will work |
分析 我不确定这次考试他是否会成功,但是如果他学习努力一些,他会做的更好.
解答 答案:C.
第一个设空处考查if引导的宾语从句的时态,主句I'm not sure 是一般现在时,根据句意"我不确定这次考试他是否会成功""成功"这件事还未发生,所以用一般将来时,一般将来时的构成是:主语+will+动词原形;第二个设空处考查if引导的条件状语从句的时态,句意为:"如果他学习努力一些,他会做的更好.",主句用了一般将来时,根据"主将从现"原则,从句用一般现在时,所以选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.
