英语提升:代词的用法

It的用法
1.作人称代词

John likes playing Pingpong./ He always does it in the afternoon.(指代上下文提到的事物);/It's time we went home. / How far is it from here to your home ? / It is getting warmer and warmer./ It's very quiet at the moment.(可指时间、天气、环境等)

2.引导词

A.作形式主语,代替由不定式、动名词或从句表示的真正主语。

It's important for us to learn a second language./ It's no use talking to him./ It's known to all that the earth goes round the sun.

B.作形式宾语,代替由不定式、动名词或从句表示的真正宾语。

We feel it our duty to help others./ He made it clear that he would leave the city.

C.强调结构:It is (was) +被强调部分+that (或who)…

注意:在强调结构中,如被强调部分为时间状语或地点状语,其后的连接词也绝不能为when 或where,而应用that 。在复习中,一定要注意句式的不同。

It was in Shanghai that I bought the guitar.(that引起强调句)

It was Shanghai where I bought the guitar.(where引起定从)

It was twelve o'clock when we arrived there.(when引起时间状语从句)

It was at twelve o'clock that we arrived there.(that 引起强调句)

3. it,one,that 的区别:
one 用以指代同类事物中的任一,that 特指性强,指代可数与不可数词,而it指代上文提过的同一事物。

 
不定代词

不定代词种类较多,用法各异,在使用中一定要注意区别。

1、both,either ,neither 都表两者范围,在句中作主语、宾语、定语 ,both可用作同位语。both 意为"两者都",either 表"两者中任一个",neither表"两者都不"。

2、any,none ,all 表三者或三者以上范围,any 表任何一个、一些(不可数或复数概念,用于否定句、疑问句或条件从句中);none 表三者或三者以上中的哪一个都不;表示不可数物中的一点儿也没有;all 整个的;所有的(三者或三者以上);所有的(不可数)。

e.g.This book is a good seller,so you can buy it at any shop in Beijing./ None of us are/is perfect./ All of the village was flooded.

3、no one,nobody,none,nothing:no one,nobody表没有人,nothing 指没有什么事物,none 兼指人和物。none 着眼于数量概念。"特指的人或物一个也没有,一点儿也没有"。

—How many people are there in the hall ? —None.

—who wants to go with him ? —No one(Nobody).

—What can you see in the bottle ?—Nothing.

—Is there any water in it ?—None.

4、another,the other,the other+复数名词(或the others),other (或other +复数名词):another 表三者或三者以上范畴中的任一;与数词连用,表"再有";the other 表两者中的另外那个,特指;the other+复数名词(或the others),另外那些,表示其余所有的人或物,用于特指;others (或other+复数名词)另一些,表余下人或物中的另一些,泛指。

—I don't like this,show me another one.
