it的用法及练习
英语中it的用法及练习
一、概述
在英语中，it的使用相当广泛，它既可用作代词，如人称代词（personal it）、指示代词（demonstrative it）及非人称代词（impersonal it）, 也可用作引导词（anticipatory it）和强调结构中的强调词（emphatic it）
Someone is ringing the doorbell. Go and see who it is.有人在按门铃。去看看是谁。（人称代词）
二、代词it, that, one, the one 的辨析
1）It: 所指的名词就是前面提到的同一物，相当于the + 名词为特指。
This is my bike, and I bought it last week.
2）That：可替代单数可数名词或者不可数名词，所指的名词与前面提到的为同一类，而非同一物，为特指。The climate of my native town is not so warm as that of Taiwan.
3）One：代替可数的单数名词，相当于a + 名词，所指的名词与前面提到的为同一类，而非同一物，为泛指。
I have lost my pen; I think I must buy another one.
4）The one：表示特指的人或物
He doesn’t like this pen. He likes the one you lent to Jim.
5）Ones：代替可数的复数的复数名词，不能单独出现，前面应有形容词修饰。
I’d like to have some big apples instead of small ones.
二、it作代词
1、用作人称代词（personal it）
代替前文提到过的事物，it作真实主语或宾语。
2、用作指示代词（demonstrative it）
相当于this或that，it有时不特指某件东西，而代表前面已提到的或将会发生的某件事情。
-Who is knocking at the door? —谁在敲门？
-It's me. —是我。
3、用作非人称代词（impersonal it）
代词it可用来指除人以外的一切生物和事物，无阴阳性之分。可指时间、距离、度量、价值、自然现象（天气、气体、阴暗等）。
-What's the time? —“几点了？”-It's half past ten. —“十点半”（指时间）
It is late autumn now. 现在是深秋。（指时间）It is rather cold today, isn't it?今天很冷，是不是？（指天气）
-How far is it from here to the station? —从这儿到车站有多远？
-It's about two kilometers. -大约两公里。（指距离）It is raining hard. 雨下得很大。（指自然现象）
-What's the cost of the dictionary? 那本词典多少钱？It is sixty-three. 六十三元（指价值）
It did not snow much last winter. 去年冬天雪下得不多。（指自然现象）
三、it作引导词
1、作形式主语（formal subject）
当主语是动词不定式短语、动词的-ing形式短语和主语从句时，为了避免头重脚轻，往往把主语放在谓语动词之后，习惯上用it作形式主语来指代后面的真实主语。这个it称为引导词（anticipatory）it，作形式主语，放在谓语动词后的主语是真正的主语。
2、作形式宾语(formal object)
当复合宾语中的宾语是动词不定式、动词-ing形式短语、宾语从句时，往往把宾语放在它的补足语的后面，而把引导词it放在全句谓语动词和宾语补足语的中间。放在宾语补足语后面的宾语叫真正宾语，放在全句谓语动词和宾语补足语中间的引导词it叫形式宾语。
四、it用在强调结构中
当我们要强调句子的某一部分（通常总是主语，宾语或状语）时，常用强调结构。其形式为“it is (was)+被强调的部分+who(that)+句子的其它成分”。在这种结构中，it无实际意义，它只帮助改变一个句子的结构，使某一成分受到强调。如I told her the news at the gate yesterday. 这个句子就可借助it改为下列几种形式，各强调一个不同的成分。
