名词性从句写作

名词性从句

名词性从句包括四种从句即主语从句、表语从句、宾语从句和同位词从句。

引导名词性从句的关联词有以下三类：

从属连词：that, whether, if, as if (用于表语从句)

连接代词：who, what, which, whom, whose，whatever, who, whoever,等

连接副词：when, where, why, how以及由how组成的词组how many, how long, how far等I. 主语从句

主语从句: 通常放在主句谓语动词之前或由形式主语it代替，而本身放在句子末尾。

it作形式主语的几个主要句型

1.It + be+名词词组(no wonder, an honor, a good thing, a pity, no surprise, etc.) + that从句

It’s a pity that we can’t go .

2.It +be +形容词(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+ that从句

It is certain that she will do well in her exam.

3.It + be+ 过去分词(said, reported, thought, expected, decided, announced, etc.)+ that从句

It is said that Mr. Green has arrived in Beijing.

4. It +不及物动词(seem, happen等) +that从句

It seemed that Alice is not coming to the party at all.

5. It doesn’t matter (makes no difference, etc.)+连接代词或连接副词引起的主语从句。

It doesn’t matter whether she will come or not. 她是否来这无关紧要。

II. 表语从句

1.as if常与look, seem, sound等连系动词连用.

由as if ,as though引导表语从句时要注意语态.若从句表示与现在事实相反,谓动用一般过去式（be用were）,与过去事实相反用had+p.p. 或表示将来的可能性不大，则用would(might,could)+v原型.

She looks as if she would cry.

2.在一些表示“建议，劝说，命令”的名词后的表语从句中，谓语动词用虚拟语气。

My suggestion is that we（should）start early tomorrow.

III. 宾语从句

1.动词find,feel,think,consider,make,believe,guess,suppose,assume等后有宾语补足语时，则需要用it作形式宾语，而将宾语从句后置。

I made it clear to them that they must hand in their papers before 10 o’clock in the morning.

2.有些动词带宾语从句时，需要在宾语从句前加it，这类动词(短语)主要有：hate,like,owe,have,appreciate,see to等

I hate it when they talk with their mouths full of food.

IV. 同位语从句

1.同位语从句的先行词多为fact, news, idea, thought, question, reply, report, remark, belief, doubt, rumour, order, hope, reply, problem, reason, suggestion, advice, saying, answer, information, possibility, message, word, promise, truth, plan, opinion, problem, question, decision,等等。（位置：同位语从句常紧跟这些名词之后；但有时被其它词隔开，称作分

式同位语从句) 关联词多用从属连词that.

Where did you get the idea that I could not come?

They were all very much worried over the fact that you were sick.

2.表示“建议、命令、要求”的名词如suggestion, advice, proposal, desire, demand, request, requirement, order, decision, command后所跟的同位语从句中，谓语动词用虚拟语（should+动词原形，should可省略）

This is our only request that this (should) be settled as soon as possible.
