题目内容
8.Video games can be a poor influence if __________ in the wrong hands.( )A. | to leave | B. | leaving | C. | leave | D. | left |
分析 电脑游戏可能会有不好的影响,如果它们被操作不当.
解答 答案:D
由于Video games和leave之间是被动关系,故用被动语态.因为在if引导的条件状语从句中,遵循"主将从现"的原则,所以用一般现在时的被动语态.又由于此句是省略句,在if引导的条件状语从句中,如果主、从句的主语一致,而且从句又有be时,常常省略主语和be.所以选D项.
点评 此题考查两点:一般现在时的被动语态和if引导的条件状语从句的省略.掌握了"在if引导的条件状语从句中,如果主句是将来时,那么从句要用一般现在时代替."这一语法现象,解决此类题就不难了.
