考研英語春季語法復(fù)習(xí)：連詞“that”的用法
在考研英語閱讀中，我們常常會遇到連接詞that省略的情況。而一旦省略，對同學(xué)們的從句識別和判定會帶來一定的困難，從而影響閱讀的理解和翻譯。今天醫(yī)學(xué)全在線英語指導(dǎo)老師就帶著同學(xué)們看一下在三種從句中連接詞that省略用法的幾種情況。
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(shí)，往往可省略。如：
(1)John once talked to his mom about the cities(that)he had visited apoad.
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(shí)，不可省略。如：
(1)The teacherthatis kind to us goesback home very late every day.
在從句中that作主語，故不可以省略。
(2)My old schoolthatwas 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(shí)醫(yī).學(xué)全.在.線gydjdsj.org.cn，有時(shí)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(shí)，充當(dāng)連詞，本身無實(shí)際意義。
1. that在引導(dǎo)賓語從句時(shí)，通�？墒÷�。如：
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(shí)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(gè)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(gè)賓語從句連用時(shí)，即使省略了第一個(gè)that，也不可省略第二個(gè)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(shí)，不可以省略that。如：
He has told me that he will go to Shanghai tomorrow.
2. that引導(dǎo)主語從句醫(yī)學(xué)全.在線gydjdsj.org.cn、同位語從句及表語從句時(shí)，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 youdidn’tgo 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) youdidn’tgo to the party.
三、that引導(dǎo)狀語從句時(shí)，充當(dāng)連詞，有時(shí)也可省略。
1.在結(jié)果狀語從句中，that有時(shí)可以省略。如：
The sound is so weak(that)you can’t hear it.
總之，that的省略現(xiàn)象在英語學(xué)習(xí)中很普遍，尤其是在定語從句和賓語從句中，大家遇到這兩種句型時(shí)要多加留心that是如何使用的，注意總結(jié)。另外，如果大家對that省略的情況把握不好，提醒同學(xué)們在寫作時(shí)最好不要省略that。
