關(guān)系代詞which, that引導(dǎo)的定語(yǔ)從句:

如果先行詞是表示物體的名詞或代詞，關(guān)系代詞應(yīng)用which, that(作主語(yǔ)或賓語(yǔ))

定語(yǔ)從句關(guān)系副詞的用法:

1、Where指地點(diǎn)，在從句中充當(dāng)?shù)攸c(diǎn)狀語(yǔ)。

This is the place where we lived ten years ago.

=in which

2、When指時(shí)間，在從句中充當(dāng)時(shí)間狀語(yǔ)。

He told me the date when he joined the Party.

=on which

3、Why指原因，在定語(yǔ)從句中充當(dāng)原因狀語(yǔ)。

I know the reason why she was so angry.

=for which

關(guān)系副詞when, where和關(guān)系代詞that, which的區(qū)別:

同樣是修飾一個(gè)地點(diǎn)，有時(shí)使用where,有時(shí)使用that/which;

同樣是修飾一個(gè)時(shí)間，有時(shí)使用when,有時(shí)使用that/which。這主要看兩點(diǎn)：

1、先行詞在從句中所作成分;

2、定語(yǔ)從句中的謂語(yǔ)動(dòng)詞是否 一個(gè)及物動(dòng)詞。

1.This is the park (which/ that )we visited last year.

This is the park where we held a birthday party.

= in which

2. She won’t forget the days (which/ that) she spent on the island.

She won’t forget the day when they stayed together.

= on which

分析例題：

1) This is the factory _ _ I visited last year.

2) This is the factory _ _ I worked last year.

3) This is the factory produces all kinds of TV sets.

A. where B. which C. whom D. whose

以上三個(gè)句子只有細(xì)微的差別，但答案卻不同：做這種題時(shí)，要通過(guò)還原先行詞,看先行詞在定語(yǔ)從句中所充當(dāng)?shù)某煞?

1)還原為: I visited the factory.是動(dòng)賓關(guān)系，因此選 which

2)還原為: I worked in the factory，factory應(yīng)在定語(yǔ)從句中作地點(diǎn)狀語(yǔ)，因此選 where

3)還原為: the factory produces all kinds …是作定語(yǔ)從句中的主語(yǔ)，不作地點(diǎn)狀語(yǔ)，因此選which

4)Can you lend me the novel _ _ the other day?

A. that you talked

B. you talked about it

C. which you talked with

D. you talked about

還原后為：You talked about the novel the other day.故it要?jiǎng)h掉，先行詞在句中作賓語(yǔ)，關(guān)系代詞可以用which/that或者不填。
