宾从： I wonder where you went just now.

当主句为现在时态从句时态不受影响， 当主句为过去时态从句就应该变成过去的某种时态， 但客观真 理总用一般现在时，有固定过去时间总用过去时。

高频考点 1， 当主从句都缺成分时指物用 what/whatever/whichever （ 有范围 ）, 指人用 whoever / whomever （ 做宾语 ）.

The buildings have been built in _what_ was farmland. _What_ you need is courage.

The prize will be awarded to _whoever_ has won the game. You can choose _what/whatever/whomever_ you like. Of all, you can choose _whichever_ you like .

2, No matter+ 疑问词，只能引导让步状语从句（主从句逗号分开） ， 疑问词 +ever 既可引导让步状从， 又可引导名从（从句在主句中做成分） 。

No matter who / whoever- has broken the law , he

ll be punished . _Whoever_ has broken the law will be punished.

3, 抽象名词( fact, news/word, hope, desire, thought, suggestion, idea, problem, possibility/chance ,rumor, concept ?)后常用that 引导同从。

News /word came that you had passed the exam.

There is no possibility/ chance that he ' ll come.

解题方法：1，看主句表肯定还是不肯定，主句肯定从句完整根据句意从that 和连接副词中选择；从句不完整根据句意看所缺成分从连接代词中选择。2，不肯定时从句完整根据句意从whether 和连接副词中选择；不完整时根据句意看所缺成分从连接代词中选择。
