从高考题看“It” 用法与考点延伸摘要本文笔者从高考题讲述“It”的用法和考点,及其主要的句型。
关键词高考题用法考点一.It用法透析:1.It可用作人称代词,代替前文出现的事物,也可用以代替指示代词this和that。
2.It作非人称代词,表示时间、日期、地点、天气、温度、距离、环境等。
3. It 用作形式主语或宾语,代替不定式, 动名词或从句4. It 也可用在强调句型中,对谓语动词之外的成分加以强调。
常用句型为:“It is /was + 被强调成分+that (who/ whom)+句子其他成分”二.It 的考点延伸1. it /that /one 的区别(2010陕西卷12). The cost of renting a house in central Xi’an is higher than ____in any other area of the city.A. thatB. thisC. itD. one此题的正确答案为A. This为指示代词,指代下文即将提到的事物;That除作指示代词外,还可指代前面出现的同类名词,相当于the +名词;It指代“同类中的同一物”;One虽指同类但不是同一物体,表示“某一个”的含义。
2. It应用的强调句型与定语从句、状语从句或名词性从句混搭判断是否强调句型的方法是将强调结构去掉之后,如句子表述仍完整,则为强调句型,反之则不是。
(07山东)---Where did you get to know her?--- It was on the farm ____ we worked.A. thatB. thereC. whichD. where此题的正确答案为D。
这是一个省略句,完整表达应该为:It was on the farm ______ we worked that I got to know her。
分析句式应该为定语从句,farm在从句中充当的成分为地点状语,选择关系副词where。

⑶it用作形式主语或形式宾语:根据句子结构的需要,人们常用it作形式主语或宾语,而把真正的主语或宾语(不定式短语、动词-ing短语或名词性从句)放在句末。
注意it作形式主语的常见结构有:①It+ be + adj/n(for sb)to do sth.②It +be + adj of sb to do sth.③It +be + adj /n + doing sth(一般限于名词fun,good,luck,joy,use,pleasure或形容词foolish,wonderful,good,nice,interesting,useless,worth等作表语时,才用it作形式主语,将真正的动名词主语后置)④It +be + adj./n + that-clause.⑤It +be+过去分词(如said,proved,known,believed,reported,thought,hoped,decided,announced, suggested,ordered,demanded,proposed,requested,advised等)+that-clause.注意如果表语是划线部分的词,从句应该用虚拟语气。

把握“it〞用作形式宾语的特殊构造〔附答案〕在英语中,当动词不定式、动名词或从句在句中充当宾语且其后又带有宾语补足语时,习惯上要在宾语补足语前使用一个没有具体意义的形式宾语it,而将真正的宾语移到补足语的后面,构成“动词+it+宾语补足语+不定式〔动名词或从句〕〞构造。
如:She felt it her duty (to take good care of them). 括号内为真正宾语她感到好好照顾他们是她的责任。
I think it no good going there now. 我认为现在去那里没有好处。
The headmaster has made it clear (that the school meeting will not be put off).校长说得很清楚校会不会推迟。
但我们常会碰到it用作形式宾语时之后没有形容词或名词作宾语补足语的情况,这一点在近几年高考试题中经常涉及,需引起同学们的注意。
I hate_____ when people talk with their mouths full. (NMET 1998)A. itB. thatC. theseD. them (答案为: A)我讨厌人们一边吃饭一边说话。
I like _____ in the autumn when the weather is clear and bright. (全国卷2004)A. thisB. thatC. itD. one (答案为: C)我喜欢秋天晴朗的天气。
以上这两道高考题中,it用作形式宾语,它的真正的宾语那么是由when引导的从句。
“it〞的这种特殊用法常出现在以下几种构造中。
A. 动词+it+when / if 从句。
常见于appreciate, enjoy, like, dislike, love, hate, prefer等少数动词之后。
We would much appreciate it if you could do us that favour.要是你们能帮我们这个忙,我们将非常感谢。
