成人英語(yǔ)三級(jí)語(yǔ)法知識(shí)大全七

定語(yǔ)從句

(一)定義及相關(guān)術(shù)語(yǔ)

1.定語(yǔ)從句：修飾某一名詞或代詞的從句叫定語(yǔ)從句。定語(yǔ)從句一般緊跟在它所修飾的先行

詞之后。

2.先行詞：被定語(yǔ)從句修飾的詞叫先行詞。

3.關(guān)系詞：引導(dǎo)定語(yǔ)從句的詞叫關(guān)系詞。 關(guān)系詞有關(guān)系代詞和關(guān)系副詞。關(guān)系代詞有that, which, who, whom, whose, as等;關(guān)系副詞有when, where, why等。關(guān)系詞通常有三個(gè)作用：

A、引導(dǎo)定語(yǔ)從句;B、代替先行詞;C、在定語(yǔ)從句中擔(dān)當(dāng)一個(gè)成分。例如： The man who is shaking hands with my father is a policeman. 該句中，who is shaking hands with my father 是定語(yǔ)從句，修飾先行詞the man， “who”是引導(dǎo)定語(yǔ)從句的關(guān)系詞，代替先行詞the man，在定語(yǔ)從句中作主語(yǔ)。

(二)關(guān)系代詞引導(dǎo)的定語(yǔ)從句

1.who 指人，在定語(yǔ)從句中作主語(yǔ)。

2.whom 指人，在定語(yǔ)從句中做賓語(yǔ)，?？墒÷浴?/p>

Mr Liu is the person ( whom ) you talked about on the bus.

劉先生就是你們?cè)诠财?chē)上談?wù)摰哪莻€(gè)人。

注意：關(guān)系代詞whom 在口語(yǔ)或非正式文體中常可用who 來(lái)代替，也可省略。

The man ( whom / who )you met just now is my old friend.

3.Which 指物，在定語(yǔ)從句中做主語(yǔ)或賓語(yǔ)，做賓語(yǔ)時(shí)常可省略。

Football is a game which is liked by most boys. 足球是大多數(shù)男孩所喜歡的運(yùn)動(dòng)。 The factory which makes computers is far away from here.

制造計(jì)算機(jī)的那家公司離這很遠(yuǎn)。

This is the pen ( which ) he bought yesterday. 這是他昨天買(mǎi)的鋼筆。 The film ( which ) they went to see last night was not interesting at all.

他們昨晚看的電影一點(diǎn)意思也沒(méi)有。

4.That 指人時(shí)，相當(dāng)于who 或whom;指物時(shí)，相當(dāng)于which。在定語(yǔ)從句中作主語(yǔ)或賓語(yǔ)，作賓語(yǔ)時(shí)常可省略。

The number of people that / who come to visit this city each year reaches one million.

每年來(lái)參觀這座城市的人數(shù)達(dá)一百萬(wàn)。

(三)“介詞+關(guān)系代詞”引導(dǎo)的定語(yǔ)從句

關(guān)系代詞在定語(yǔ)從句中作介詞賓語(yǔ)時(shí)，從句常常由“介詞+關(guān)系代詞”引出。

注意：

2. 若介詞放在關(guān)系代詞前，關(guān)系代詞指人時(shí)只可用whom，不可用who, that;關(guān)系代詞指物時(shí)只可用which，不可用that。關(guān)系代詞是所有格時(shí)用whose。

The man with whom you talked just now is my neighbour. (正)

你剛才跟他談話的那個(gè)人是我的鄰居。

The man with that / who you talked just now is my neighbour. (誤)

3.“介詞+關(guān)系代詞”前還可有some, any, none, all, both, neither, many, most, each, few等代詞或者數(shù)詞。如：

(四)關(guān)系副詞引導(dǎo)的定語(yǔ)從句

難點(diǎn)釋疑：

(一)限制性定語(yǔ)從句中只能用that 引導(dǎo)定語(yǔ)從句的情況。

1.當(dāng)先行詞是everything, anything, nothing (something 除外), all, none, few, little, some等代詞時(shí)，或當(dāng)先行詞受every, any, all, some, no, little, few, much等代詞修飾時(shí)。如：Have you taken down everything that Mr. Li said? 李老師講的你都記下來(lái)了嗎?

任何有責(zé)任感的人都不會(huì)做這樣的事。

所有應(yīng)邀來(lái)參加她婚禮的客人都是重要人物。

2.當(dāng)先行詞被序數(shù)詞修飾時(shí)。

如：The first place that they visited in London was the Big Ben.

在倫敦他們參觀的第一個(gè)地方是大本鐘。

3.當(dāng)先行詞被形容詞最高級(jí)修飾時(shí)。

如：This is the best film that I have ever seen. 這是我看過(guò)的最好的電影。

4.當(dāng)先行詞被the very, the only修飾時(shí)。

如：This is the very dictionary that I want to buy. 這正是我要買(mǎi)的詞典。

瞧瞧那個(gè)沿街走來(lái)的人和他的 毛驢。

(二)關(guān)系代詞as和which 引導(dǎo)的定語(yǔ)從句

as 和which 引導(dǎo)非限制性定語(yǔ)從句時(shí)， 其用法有相同之處，也有不同之處。

1. as 和which都可以在定語(yǔ)從句中做主語(yǔ)或賓語(yǔ)，代表前面整個(gè)句子。如：

He married her, as / which was natural. 他跟她結(jié)婚了，這是很自然的事。

He is honest, as / which we can see. 他很誠(chéng)實(shí)， 這一點(diǎn)我們看得出來(lái)。

2. as 引導(dǎo)的非限制性定語(yǔ)從句可以放在主句之前、主句之后，甚至還可以分割主句。 which 引導(dǎo)的非限制性定語(yǔ)從句只可放在主句之后。另外，as 常常有“正如、正像”的含義。如：

As is known to all, China is a developing country.

眾所周知，中國(guó)是發(fā)展中國(guó)家。

He is from the south, as we can know from his accent.

張華已去過(guò)巴黎十多次了，這一點(diǎn)我不相信。

注意：當(dāng)主句和從句之間存在著邏輯上的因果關(guān)系時(shí)，關(guān)系詞往往只用which。如： Tom was late for school again and again, which made his teacher very angry.

湯姆老是遲到，這使得老師很惱火。.

These tables are made of metal, which made them very heavy.

這些桌子是金屬的，這使得這些桌子很重。

3. 當(dāng)先行詞受such, the same 修飾時(shí)，關(guān)系詞常用as。 如：

I’ve never heard such stories as he tells. 我從未聽(tīng)過(guò)象他講的這樣的故事。

He is not such a fool as he looks. 他可不象他看上去的那樣傻。

This is the same dictionary as I lost last week. 這部詞典跟我上星期丟失的一樣。(三) 以the way為先行詞的限制性定語(yǔ)從句通常由in which或that引導(dǎo)，而且通?？梢允÷?。

The way (that / in which ) he answered the questions was surprising.

他回答這些問(wèn)題的方式令人驚奇。

I don’t like the way (that / in which) you laugh at her. 我不喜歡你沖她的樣子。

(四)關(guān)系代詞與關(guān)系副詞的選擇

用關(guān)系代詞還是關(guān)系副詞引導(dǎo)定語(yǔ)從句主要看關(guān)系詞在定語(yǔ)從句中的作用(即所擔(dān)當(dāng)?shù)某煞?。 試比較：

A. I know a place where we can have a picnic.

我知道一個(gè)我們可以野炊的地方。

This is the reason that / which he explained to me for his not attending the meeting.

這就是他向我解釋的他沒(méi)有參加會(huì)議的原因。.

(五)定語(yǔ)從句與同位語(yǔ)從句的區(qū)別

1.定語(yǔ)從句修飾限定先行詞，它與先行詞是修飾關(guān)系;同位語(yǔ)從句說(shuō)明先行詞的具體內(nèi)容，

它與先行詞是同位關(guān)系。

The plane that has just taken off is for Paris.(定語(yǔ)從句)

剛起飛的那架飛機(jī)是開(kāi)往巴黎的。

The fact that he has already died is quite clear.(同位語(yǔ)從句)

他已去世了，這個(gè)事實(shí)很明了。

2.定語(yǔ)從句由關(guān)系代詞或關(guān)系副詞引導(dǎo)，關(guān)系詞在從句中擔(dān)當(dāng)相應(yīng)句子成分，關(guān)系代詞在從句中作賓語(yǔ)時(shí)經(jīng)?？墒÷?。同位語(yǔ)從句主要由連詞that 引導(dǎo)，在從句中一般不擔(dān)當(dāng)成分;有時(shí)由where, when, how, who, whether, what 等連詞引導(dǎo)，這些連詞則在從句中擔(dān)當(dāng)成分。

The news that he told me is true. (定語(yǔ)從句)他告訴我的消息是真的。

他是否一定會(huì)贏得那場(chǎng)比賽，這個(gè)問(wèn)題很難回答。

3.同位語(yǔ)從句與先行詞一般可以用動(dòng)詞be發(fā)展成一個(gè)完整的句子,定語(yǔ)從句則不能。

A. The idea that he we could ask the teacher for advice is wonderful. (同位語(yǔ)從句)

我們可以向老師請(qǐng)教，這個(gè)主意不錯(cuò)。
