题目内容
6.Your computer will go wrong if you _____ games too often on it.( )| A. | play | B. | plays | C. | playing | D. | will play |
分析 如果你经常玩电脑游戏,你的电脑将会出问题的.
解答 答案:A.
if表示如果,引导的条件状语从句,遵循主将从现的规则,从句主语you,故play,故答案是A.
点评 条件状语从句时意为"如果",如果引导宾语从句则意为"是否".请比较:
1)We will go out if it is fine tomorrow.
2)I don't know if the train has arrived.
句1)中if引导的是状语从句.这个从句表示"条件",整个句子的意思是"如果明天天气好,我们就出去".句2)中if引导的是宾语从句,充当谓语动词don't know的宾语,整个句子的意思是"我不知道火车是否到了".
