一、名词从句的虚拟语气

1.基本用法

Used when we say that things are (un)important or (un)desirable. 当我们说某件事情是否重要或者是否是渴望得到的时候

形式：(should) + 动词原型

It’s important that the child go to a first-class school.这里不要误以为是 goes, 表达虚拟语气时，用的是 (should) go,should 可以省略

We were anxious that everybody (should) receive the information as soon as possible.

He suggested that I (should) move to another city. 这里表达时一个过去的动作

Eric is concerned that the club close Eric 担心这个俱乐部会关门

He says that the club is closing.

The doctor recommends that she

It’s important that somebody (should) talk to the policeman.

She wished (or It was her wish) that her money (should) go to charity.

I insisted that the contract (should) be read aloud.

2.should + 动词原型

① Used after words expressing the importance of an action 往往表达事物的重要性。

② Used after words expressing personal reactions and judgements.表达个人的反应和判断

It’s surprised that you (should) say that to me.

It was strange / odd that you should have invited Emma.

3.tha 引导名词从句：无含义

I heard about his idea that we should agree. 对抽象名词 idea 进行解释，同位语从句

I hope that you will be happy.宾语从句，这里的 that 可以省略

It’s essential that you come. 主语从句

My iead is that we should agree 表语从句，that 可以省略

Lucy said that she was feeling better. 这里的 that 也可以省略
注：以上均无含义，只起到语法上引导从句的功能，表达含义上来看，不需要考虑，且当 that 引导宾语从句时，可以省略，表语从句的that 也可省略，但是主语从句和同位语从句的不可省略。

二、主语从句的转化

1.形式： the fact that …

That she was foreign made it difficult for her to get a job.
The fact that she was foreign made it difficult for her to get a job.

三、WH-引导名词从句

who、when、where、why、what、which、（how）

主语：Who you invite is your business. 形式主语

宾语：Do you see how he treats me? how diverse … 直接引语变间接引语

     ~~~~      how + 形容词、副词 表示多么，是程度副词

     ~~~~      I often think about where I met you. 介词后的宾语从句

表语：A hot bath is what I need.

同位语从句：whether

     ~~~~      I have no idea whether it will rain or not

     ~~~~      Eric told me where he was going.

     ~~~~      Ask her when she will be ready.

I’m surprised at her speed.
I’m surprised at how fast she can run.(相较而言比较不正式)

形式主语/主语从句：变成尾重的形式

Who you invite is your business.
It is your business who you invite.

whether / if ：直接引语是一般疑问句的时候，将其转化为名词从句，需要使用 whether 这个词。《

Whether you love me really matters. whether 引导主语从句

She asked me whether I loved her. 宾语从句

The question is whether you love me.表语从句

注：在句首只能用 whether

Whether you can stay here isn’t yet certain.

Whoever、Whatever 、Whichever

Whoever phoned just now was very impolite. 主语从句

Use whichever room you like. 宾语从句，这个词再引导名词从句时必须加名词

Whatever is in that box is making a funny noise. 主语从句

形式主语 ☆☆☆

That he hasn’t phoned is odd. 头重脚轻
It is odd that he hasn’t phoned.

It’s amazing that she can speak so many languages.
It’s amazing how many languages she spoke.

To read page 154 is important.
It is important to read pay 154.

It is good to relax at the beach.

形式宾语

① 当句中有宾语补足语时，且宾语较长（宾语从句/不定式）

I find it odd that Eric is away.

Lucy’s blister made it a problem to walk.

I find it difficult to make sentences with correct grammatical rules.

regard / consider / view / see … as …

注：两个条件：宾语补足语 宾语较长做宾语从句或不定式时

形式宾语的特殊使用情况

1、owe it to … to do … 把 … 归因于
     ~~~~      leave it to … to do … 把做 … 事情留给谁
We owe it to the government to help those who need help.
