高中英语讲义---- 名词性从句（主从、表从、宾从，同从）
1， 陈述句做名从用连词that + SV, that 表主句肯定从句完整，不做成分。主从可用it 做形式主语，宾从第一
个that 可省略。 You study hard.
主从：That you study hard is known to us.= It is known to us that you study hard. 表从：My opinion is that you study hard .
宾从：I think (that) you study hard. …and that (不能省略)….
同从：My opinion that you study hard is known to us. *比较同从和主从！
? 一般抽象名词后对其进行解释和说明的完整句子就是其同位语从句，不完整就是定语从句。
I appreciate your idea that we have an exam every week. （that后完整—同从）
I appreciate your idea that you came up with last time.（that后不完整---定从）
2， 一般问句做名从用连词whether(是否) + SV，whether表主句不肯定从句完整，宾从中可用if（介词后或宾
从后有or not时只用whether）。 Does your friend like English ?
主从：Whether your friend likes English isn’t clear .=It isn’t clear whether your friend likes English. 表从：My question is whether your friend likes English. 宾从： I don’t know whether/ if your friend likes English. 同从：My question whether your friend likes English isn’t clear.
3, 特殊问句做名从用疑问词（连词）+ SV, 疑问词做主语时直接+谓语。连接代词（what/which/who/whose…）表主句不肯定从句不完整，连接副词（when/where/why/how）表主句不肯定从句完整。 Where did you go just now ?
主从：Where you went just now isn’t clear.= It isn’t clear where you went just now. 表从：My question is where you went just now. 宾从：I wonder where you went just now.
同从：My question where you went just now isn’t clear.
? 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 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。
