(完整版)高中名词性从句全面讲解及练习(含答案)

高中英语讲义一名词性从句（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 th in k （that） you study hard. -and that （不能省略）….

同从：My opi nion 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 后完整一同从）

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 'clear .=It isn 'clear whether your friend likes English.

表从：My question is whether your friend likes English.

宾从：I don 'know whether/ if your friend likes English.

同从：My question whether your friend likes English isn '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（w he n/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 'clear.= It isn 'clear where you went just now.

表从：My questi on is where you went just now.

宾从：I won der where you went just now.

同从：My question where you went just now isn '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 buildi ngs have built in _what_ was farmla nd. _What_ you n eed 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 broke n the law , he ll'be puni shed .

_Whoever_ has broke n the law will be puni shed.

3, 扌由象名词(fact, news/word, hope, desire, thought, suggestion, idea, problem, possibility/chanee ,rumor, concept…)后常用that引导同从。

News /word came that you had passed the exam.

There is no possibility/ chanee that he 'Icome.
