定語從句的七大考點

定語從句是在主句中作定語，緊跟在先行詞（被修飾的名詞）之后的從句。定語從句分為限制性的定語從句（從句在句中是不可缺少的部分，主句和從句之間不用逗號隔開）和非限制性的定語從句（從句是對主句的先行詞的補充和說明，沒有從句不影響主句的意思完整。主句和從句之間用逗號隔開）。定語從句一直是高考考查的重點內(nèi)容。

[關(guān)系代詞和關(guān)系副詞的選擇]

定語從句中關(guān)系代詞和關(guān)系副詞的選擇主要根據(jù)先行詞在定語從句中充當?shù)某煞謥頉Q定。如果它在句中作主語、賓語、表語或定語，則用關(guān)系代詞who（m），that，which，as，whose；如果作狀語，則用關(guān)系副詞when，where，why。比較如下：

who 指代人，在從句中作主語，間或作賓語。

which 指代物，在從句中作主語或賓語。

關(guān)系代詞

that 可用于指代人，也可以用于指代物；在從句中作主語或賓語。

whose 表示所屬關(guān)系，用于指代人或物，在從句中作定語。

when 表示時間，在從句中作時間狀語。

關(guān)系副詞

where 表示地點，在從句中作地點狀語。

why 表示原因，在從句中作原因狀語。

[that與which，who，whom的用法區(qū)別]

1. 只能用關(guān)系代詞that的情況

當先行詞為all，everything，anything，nothing，little，much，等不定代詞時；

當先行詞被all，any，every，each，much，little，no，some，few等修飾時；

當先行詞有形容詞最高級和序數(shù)詞修飾時；

當先行詞既指人又指物時；

當先行詞被the only，the very修飾時；

當句中已經(jīng)有who或which時，為了避免重復(fù)時。

2. 只用which，who，whom的情況

在非限制性定語從句中，只能用which指代物，用who/whom指人；

在由“介詞+關(guān)系代詞”引導(dǎo)的定語從句中，只能用which指物，whom指人；

當先行詞本身是that時，關(guān)系詞用which，當先行詞為those，one，he時多用who。

[特殊先行詞引導(dǎo)的定語從句]

1. 英語中一些特殊的先行詞，如：case，degree，stage，point，position，situation，activity，business，family等，表示“情況、方面或處境”等含義時，而且關(guān)系詞在從句中作抽象意義上的地點狀語，意思是“到了某種地步，在某種境況中”，此時用where引導(dǎo)定語從句。

2. 當先行詞occasion，point，stage表示“時間點或時間段”，且其后的關(guān)系詞在從句中作時間狀語時，用when引導(dǎo)定語從句。

3. 當先行詞為way時，若在從句中作狀語，表示“用這或那種方式/方法（=in this/that way）”時，通常不用關(guān)系詞，偶爾用that，在較正式的文體里才用in which。若在從句中作主語或賓語，則用which或that。

4. 當先行詞為reason時，若在從句中作狀語，用why引導(dǎo)定語從句。若在從句中作主語或賓語，則用which或that。

[“介詞+關(guān)系代詞”引導(dǎo)的定語從句]

用于這種情況的關(guān)系代詞一般是whom（指人、賓語），which（指物，賓語），whose（指人或物，定語），不可用that或who。在這種結(jié)構(gòu)中，介詞的選擇遵循以下四個原則：

1. 根據(jù)定語從句中的謂語動詞確定介詞，該動詞與介詞搭配，構(gòu)成固定的動詞短語。

2. 根據(jù)定語從句中的形容詞確定介詞，該形容詞與介詞搭配，構(gòu)成固定的形容詞短語。

3. 根據(jù)定語從句所修飾的名詞確定介詞，這些名詞往往表示時間、地點、原因、方法、工具等，它們與介詞有一定的聯(lián)系。當“介詞+關(guān)系代詞”在定語從句中充當時間、地點、原因狀語時，可分別用when，where和why替換。

4. 根據(jù)句意確定介詞。有些句子的先行詞完全一樣，定語從句中謂語動詞不是由固定的動詞短語構(gòu)成，這時，要根據(jù)句子要表達的意思，選用不同的介詞。

[which和as引導(dǎo)的非限制性定語從句]

關(guān)系代詞which引導(dǎo)非限制性定語從句時，除了指物外，更多的是指整個句子或主句的部分內(nèi)容，在定語從句中作主語或者賓語。which引導(dǎo)的從句常置于句中或句末，譯作“這，這一點”。

as引導(dǎo)的非限制性定語從句可以置于主句之前、之后或期間，用逗號隔開，譯作“正如……”。常用形式有：

as we can see 正如我們所看到的

as we had expected 正如我們所預(yù)料的

as is shown in the figure 如圖所示

as引導(dǎo)非限制性定語從句還用于固定搭配，先行詞與as，so，such，the same連用。如：

There is so warm a house as we want to live in.

She will marry as rich a man as she can find.

注意 the same ... that ...表示“同一物”；the same ... as ...表示“同類人/物（另一個）”。如：

This is the same pen that I lost.

這就是我丟失的那支鋼筆。

This is the same pen as I lost.

這是和我丟失的那支鋼筆一模一樣的鋼筆。

such ... as ...引導(dǎo)定語從句，意為“像……那樣”；such ... that引導(dǎo)狀語從句，意為“如此……以致……”。如：

This is such an easy question as I can answer.

這是一個我都能回答的簡單問題。（定語從句）

This is such an easy question that I can answer it.

這個問題如此簡單，我都能回答。（狀語從句）

[定語從句與同位語從句的區(qū)別]

定語從句與同位語從句結(jié)構(gòu)很相似，但它們有本質(zhì)區(qū)別。定語從句對其前的先行詞起修飾或限制的作用，定語從句的引導(dǎo)詞在定語從句中充當一定的成分。同位語從句對其前的名詞起解釋、說明的作用，引導(dǎo)詞that在同位語從句中不作任何成分，只起引導(dǎo)詞的作用。如：

We heard of the news that he didnt want to tell us. （定語從句）

[考查定語從句與地點狀語從句的區(qū)別]

where引導(dǎo)的定語從句與地點狀語從句也很容易混淆。where引導(dǎo)的定語從句其前必須有一個表示地點的名詞或代詞充當先行詞，定語從句對該名詞或代詞起修飾或限制的作用，where也可換成“介詞+which”的形式。where引導(dǎo)的地點狀語從句其前沒有表示地點的名詞，地點狀語從句修飾整個主句，where也不能換成“介詞+which”的形式。如：

A new school building will be put up in the place where/in which there used to be a temple. （定語從句）

A new school building will be put up where there used to be a temple. （狀語從句）
