This ad almost made people mad when they ___TV.A.watch B.were watching C.to watch D.watching 为什么

问题描述:

This ad almost made people mad when they ___TV.A.watch B.were watching C.to watch D.watching 为什么

made people mad when they

选B when (they were) watching TV ,定语从句,表示进行中的动作,或者用省略形式的时候可以省略they were

选B.
①划分句子成分和结构有助于理解句意和句子内容:
【This ad 主语】【almost made 谓语】【people宾语】【 mad 宾补】【when they ___TV 状语从句】
②根据成分划分可知,状语从句部分,有句子主语【they】,说明后面所填答案应该是【从句谓语动词】;
③排除法:
C,D都是非谓语动词,不能直接作谓语,排除;
原句前面有主句谓语动词【 made 时态信息词】,表明是【过去时态】;
时态搭配原则:
主句是过去时,从句只能用过去的某种时态形式(客观事实、真理等除外),排除A,watch(一般现在时).
④句意表达验证:
当人们【当时正在看电视时】,这个广告几乎使人发疯了.
表达完全正确合理,因此,答案D绝对正确可靠.
⑤关键点反思:从句主语【they】出现.
如果没有这个主语they,答案可以选D,但是原句要变为——
People were almost made mad when (they were) watching TV.
没有主语they,直接用D,造成【悬垂分词】错误.

B
This ad almost made people mad when they were watching TV.
这个(插播的)广告让人抓狂。(剧情关键时刻的又较长的广告)
