that用法小議

魏會敏

that一詞在高中英語教學中應用非常廣泛。高考題型中，無論是閱讀、完型、還是填空、改錯，that一詞出現(xiàn)的頻率極高。下面就高考考點從that的詞性上進行總結(jié)。

一、用作連接詞，引導名詞性從句，即主語從句、賓語從句、表語從句和同位語從句

需要注意的是，that在賓語從句中常省略，但多個并列的賓語從句中，只有第一個that可省略。而主語從句、表語從句和同位語從句中的that是不省略的。另外，that在名詞性從句中不充當句子成分，也沒有意義。

Eg.Some people fear （that） air pollution may bring about changes in the weather around the world and that man will die out one day.（賓語從句）

What is mentioned in the report is that the number of the students in middle schools is increasing.（表語從句）

It is mentioned in the report that the number of the students in middle schools is increasing.（主語從句）

The news that is spreading around the city is that a heavy storm is coming.（同位語從句，表語從句）

二、用作連接詞，應用于副詞性從句，表示原因、條件、目的、結(jié)果，常理解為固定短語

表結(jié)果：so...that...（如此...以至于...）;such...that...（如此...以至于...）;so that（以至于）

表目的：in order that （目的是，為了）;so that（目的是，為了）;for fear that（以免，惟恐）

表原因：now that（既然）;seeing that（考慮到）;considering that（考慮到）;given that（考慮到）;not that/because...but that/because（不是...而是）

表條件：provided /providing that（如果）;suppose /supposing that（假如）;on condition that（如果）

Eg.Human facial expression differs from those of animals in that they can be controlled on purpose. （因為，由于）

Now that everybody is here，lets begin our meeting.（既然）

In order that we might see the sunrise， we started for the peak early.（為了）

三、用作連接詞，引導形容詞性從句即定語從句

與名詞性從句不同的是，that在定語從句中指代先行詞，且充當從句中的某一成分（主語、賓語或表語），一般情況下可與which互換，但下列情況下，若先行詞指代物，則只能用that。

（1）先行詞為everything ，nothing ，anything ，all ，much ，little ，none 等不定代詞或被不定代詞修飾時

（2）先行詞被形容詞最高級修飾時

（3）先行詞被序數(shù)詞修飾時

（4）先行詞被the only、the very、the same修飾時

（5）先行詞中既有人又有物時

（6）wh-開頭的疑問句中，為避免重復，關(guān)系詞用that

（7）有兩個定從時，其中一個關(guān)系代詞已用過who， which等詞時，另外一個宜用that

Eg.This is the very pen that is suitable.

This is the best place that Ive seen.

The first cake that was made was the best.

The students and the school that we visited are good.

Which is the pen that you want？

需要指出的是：

（1）定語從句中，先行詞被the same修飾時，關(guān)系詞既可以用that，亦可用as，但二者含義不同

Eg.This is the same book that Ive ever read. 這就是我讀過的那書。

This is the same book as Ive ever read. ? 這本書和我讀過的那本一模一樣。

（2）先行詞被such修飾時，關(guān)系詞可能為that，亦可能為as，但such...that...（如此...以至于...）引導結(jié)果狀語從句

such...as...（如此...的...）引導定語從句

Pop music is such an import part of society that it has even influenced our language. ?（結(jié)果狀語從句）

Pop music is such an import part of society as has even influenced our language. （定語從句）

應用于強調(diào)結(jié)構(gòu)It is...that...，若強調(diào)人，還可用It is ...who...，此時要區(qū)別于it引導的時間和地點狀語從句，時間狀語從句常用在下面的結(jié)構(gòu)中

It is/has been ?時間段since從句（時態(tài)用過去時）

It will be時間段before.從句（時態(tài)用現(xiàn)在時）

It would be 時間段before從句（時態(tài)用過去時）

It was/had been 時間段before從句（時態(tài)用過去時）

It is 時間段when從句（時態(tài)用現(xiàn)在時）

It was 時間段when從句（時態(tài)用過去時）

Eg.（1）——What time did you come back yesterday？

——It was at 12：00 that we come back.

（2）——What time did you come back yesterday？

——It was 12：00 when we come back.

（3）——It was the school where I studied 10 years ago.

（4）——It was in the school that I studied 10 years ago.

四、用作代詞，表示同類中的不可數(shù)名詞或可數(shù)名詞單數(shù)形式

此時要區(qū)別于it和one. it特指前文的同一個人或物，譯作“它”;one泛指同類中的某一個，譯作“...其中的一個”

One of the most important questions they had to consider was that of public health.

I like this house with a beautiful garden in front， but I dont have enough money to buy it.

I like a house with a beautiful garden in front， but I dont have enough money to buy one.

五、用作副詞，表示程度，相當于so

Eg.I cant walk that far.

I was that scared I didnt know what to do.

It didnt cost that much.

六、用作限定詞，指較遠的人或物，亦可指已提到過或已知的人或物

Eg.Look at that man over there.

I was living with my parents at that time.

That accident changed their lives.
