考研復(fù)習(xí)一般分為三個階段，即基礎(chǔ)備考階段、鞏固備考階段、沖刺備考階段三個階段。每個備考階段的任務(wù)都不相同，其中，基礎(chǔ)階段的備考任務(wù)主要是將基礎(chǔ)知識打牢。為了幫助考生進(jìn)行基礎(chǔ)階段的復(fù)習(xí)，唯學(xué)網(wǎng)小編整理了三種從句中連接詞that省略用法的幾種情況，以供大家查看了解。

一、that引導(dǎo)定語從句,在從句中充當(dāng)成分。

1. that在定語從句中作賓語時，往往可省略。如：

(1)John once talked to his mom about the cities (that) he had visited abroad.

在從句中that作visit的賓語，故可以省略。

(2)The homework (that )I finished last night was left at home.

在從句中that作finish的賓語，故可以省略。

2. that在定語從句中作主語時，不可省略。如：

(1) The teacher that is kind to us goes back home very late every day.

在從句中that作主語，故不可以省略。

(2) My old school that was located in the suburban was razed to the ground.

在從句中that作主語，故不可以省略。

3.that在引導(dǎo)限定性定語從句時，有時相當(dāng)于in which, at which, for which或on which, 并且在從句中可以省略。如：

(1)Attitudes towards daydreaming are changing in much the same way (that ) (in which) attitudes towards night dreaming have changed.

(2)I like the music for the very reason (that ) (for which) he dislike it.

(3)We arrived the day (that ) (on which) they left.

二、that引導(dǎo)名詞性從句時，充當(dāng)連詞，本身無實際意義。

1. that在引導(dǎo)賓語從句時，通�？墒÷浴Ｈ纾�

We know (that) sound can travel through air.

that引導(dǎo)的從句在主句中充當(dāng)know的賓語，故為賓語從句，此時that可以省略。

但：(1)在介詞短語后的賓語從句中that常不可省略，且前面往往有個形式賓語it。如:

You may depend on it that they will support your plan.

See to it that you arrive at the railway station on time.

(2)兩個賓語從句連用時，即使省略了第一個that，也不可省略第二個that。如：

I believe (that) you’ve done your best and that things will get better.

(3)在雙賓語結(jié)構(gòu)中，that從句充當(dāng)直接賓語或是間接賓語時，不可以省略that。如：

He has told me that he will go to Shanghai tomorrow.

2. that引導(dǎo)主語從句、同位語從句及表語從句時，正規(guī)語中，通常不可省略。

(1)We heard the news that our team had won.

that引導(dǎo)同位語從句，that不可以省略。

(2) The fact is that we have lost the game.

that引導(dǎo)表語從句，that不可以省略。

(3) That you didn’t go to the party was a pity.

that引導(dǎo)主語從句，that不可以省略。

不過，如果it作形式主語，that從句放在句末，可以省略that。如：

(4)It was a pity (that) you didn’t go to the party.

三、that引導(dǎo)狀語從句時，充當(dāng)連詞，有時也可省略。

1.在結(jié)果狀語從句中，that有時可以省略。如：

The sound is so weak (that) you can’t hear it.

以上為連接詞that省略用法的幾種情況，以供各位考生查看了解，如果考生對that省略的情況把握不好，建議考生在寫作時最好不要省略that。在此小編還要提醒考生，在復(fù)習(xí)英語時，切忌漫無目的背單詞、看教材，要從題型入手，有針對性地準(zhǔn)備。
