2021年高一英語語法1

同位語從句就是在復(fù)合句中作名詞的同位語的名詞性從句。

1. 同位語從句的功能

同位語從句對(duì)于名詞進(jìn)一步解釋，說明名詞的具體內(nèi)容，一般由that引導(dǎo)，例如：

1) The king's decision that the prisoner would be set free surprised all the people.

2) The order that all the soldiers should stay still is given by the general.

2. 同位語在句子中的位置

同位語從句有時(shí)可以不緊跟在它所說明的名詞后面，而是被別的詞隔開。例如：

He got the news from Mary that the sports meeting was put off.

3. 同位語從句與定語從句的區(qū)別

(1) 定語從句中的that既代替先行詞，同時(shí)以在從句中作某個(gè)成分(主語或賓語)，而同位語從句中的that是連詞，只起連接主句與從句的作用，不充當(dāng)句中任何成分。

(2) 定語從句是形容詞性的，其功能是修飾先行詞，對(duì)先行詞加以限定，描述定的性質(zhì)或特征;同位語從句是名詞性的，其功能是對(duì)名詞進(jìn)行補(bǔ)充說明。例如：

1) The news that he told me is that Tom would go abroad next year.(他告訴我的消息是湯姆明年將出國。)(第一個(gè)that引導(dǎo)的從句是定語從句，that在從句中作賓語)

2)The news that Tom would go abroad is told by him.(湯姆將出國的消息是他講的。)(同位語從句，that在句中不作任何成分)

表語從句在復(fù)合句中作表語的名詞性從句，放在系動(dòng)詞之后，一般結(jié)構(gòu)是“主語+連系動(dòng)詞+表語從句”?？梢越颖碚Z從句的連系動(dòng)詞有be, look, remain, seem等。引導(dǎo)表語從句的that?？墒÷?。另外，常用的還有the reason is that… 和It is because 等結(jié)構(gòu)。例如：

1) The question is whether we can make good preparation in such a short time.

2) This is why we can't get the support of the people.

3) But the fact remains that we are behind the other classes.

4) The reason he is late for school is that he missed the early bus.

1. 作動(dòng)詞的賓語

(1) 由that引導(dǎo)的賓語從句(that 通?？梢允÷?， 例如：

I heard that be joined the army. 我聽說他參軍了。

(2) 由what, whether (if) 引導(dǎo)的賓語從句，例如：

a) She did not know what had happened.　她不知道發(fā)生了什么。

b) I wonder whether you can change this note for me.　我想知道你是否能幫我改一下筆記。

(3) 動(dòng)詞+間接賓語+賓語從句。例如：

She told me that she would accept my invitation.　她對(duì)我說她會(huì)接受我的邀請(qǐng)。

2. 作介詞的賓語，例如：

Our success depends upon how well we can cooperate with one another.　我們的成功取決于我們之間的合作。

3. 作形容詞的賓語，例如：

I am afraid (that) I've made a mistake.　我恐怕我已經(jīng)犯了一個(gè)錯(cuò)誤。

注意：that 引導(dǎo)的從句常跟在下列形容詞后作賓語：anxious, aware, certain, confident, convinced, determined, glad, proud, surprised, worried, sorry, thankful, ashamed, disappointed, annoyed, pleased, hurt, satisfied, content 等。也可以將此類詞后的that 從句的看作原因狀語從句。

4. it 可以作為形式賓語

it 不僅可以作為形式主語，還可以作為形式賓語而真正的賓語that 從句則放在句尾，特別是在帶復(fù)合賓語的句子中。 例如：

We heard it that she would get married next month. 我聽說她下個(gè)朋就會(huì)結(jié)婚了。

5. 后邊不能直接跟that 從句的動(dòng)詞

這類動(dòng)詞有allow, refuse, let, like, cause, force, admire, condemn, celebrate, dislike, love, help, take, forgive等。這類詞后可以用不定式或動(dòng)名詞作賓語，但不可以用that引導(dǎo)的賓語從句。如：

正確表達(dá)：I admire their winning the match.

錯(cuò)誤表達(dá)：I admire that they won the match.

6. 不可用that從句作直接賓語的動(dòng)詞

有些動(dòng)詞不可用于“動(dòng)詞+間接賓語+that從句”結(jié)構(gòu)中，常見的有envy, order, accuse, refuse, impress, forgive, blame, denounce, advise, congratulate等。例如：

正確表達(dá)：He impressed the manager as an honest man.

錯(cuò)誤表達(dá)：He impressed the manager that he was an honest man.

7. 否定的轉(zhuǎn)移

若主句謂語動(dòng)詞為think, consider, suppose, believe, expect, fancy, guess, imagine等，其后的賓語從句若含有否定意義，一般要把否定詞轉(zhuǎn)移到主句謂語上，從句謂語用肯定式。例如：

I don't think this dress fits you well. 我認(rèn)為這件衣服不適合你穿。
