Ⅱ.好句——知识网络构建
1. It is Shylock who must beg the Duke to save his life.(Unit 19)
在强调句中若被强调的部分是表示人的名词，那么可以用“It is …that/who…”。但是若强调的不是表示人的名词，则用“It is…that…”。
e.g.It is in that lake that he found a crocodile.
该句型不用来强调句子的谓语，若需要强调则不需用其他的手段，应用助动词do来表示强调。
e.g.He did go to the station to meet you,but he failed to recognize you.
2. It’s uselesstrying to argue with Shylock.(Unit 19)
该句子注意用it作形式主语来代替动名词作主语的情况。
e.g.It is no use waiting here.
It’s no good helping him.He doesn’t help himself.
3. It is certain that he spent his childhood in central Europe,perhaps Germany.(Unit 20)
当it作形式主语时，该句型中只能用certain,certain还可以用在人称代词作主语的句子中。如I am certain that …。但是sure只能用于后者。
e.g.We are certain that we can win the game.
I am sure that he will win the game.= He is sure to win the game.
He is sure that he will win the game.= He is sure of winning the game.
4.Before the discoveries, it was believed that Sichuan only had a history of about 2 300 years.(Unit 20)
句型“It is/was believed that…”表示“人们相信……”，类似的句型还有：
It is said that… “据说……”，It is reported that… “据报道……”等。该类句型可以转换成sb.be believed/said/reported to …结构。
e.g.Before the discoveries,Sichuan was believed to have only a history of about 2 300 years.
5.语法提点：it的用法。
Ⅲ.好题——高考范题精讲
【例1】 (NMET 2004,27)I like ______ in the autumn when the weather is clear and bright.
A.this B.that C.it D.one
解析：该题考查代词的指代作用。根据句子中有关信息词的提示，该词应指代天气情况。
答案：C
【例2】 (NMET 2004,重庆)______ is reported in the newspapers is that talks between the two countries are making progress.
A.It B.As C.That D.What
解析：该题应该选择what来引导主语从句，但是有的同学会误认为应该用it来作形式主语。如果那样，句子应为It is reported in the newspapers that talks between the two countries are making progress.
答案：D
【例3】 (NMET 2004，广西，24)We needed a new cupboard for the kitchen.So Peter made ______ from some wood we had.
A.it B.one C.himself D.another
解析：区分it和one的指代作用。it表示特指；one表示泛指，泛指上文提到的一个可数单数名词。
答案：B
【例4】 (2002春招,30)— He was nearly drowned once.
— When was ______?
—______ was in 1998 when he was in middle school.
A.that;It B.this;This C.this;It D.that;This
解析： 本题主要考查代词的指代作用。that作为指示代词一般用来指代前面提到过的事情，而this 一般用来指代将要提到的事情。it可以用来指代事件，而在第二个空中，根据this 的用法，用this 显然不合适，故综合两者的情况，答案为A。
答案： A
【例5】 (NMET 2003上海春招，32)______ has been announced,we shall have our final exams next month.
A.That B.As C.It D.What
解析：本题题意为：正如所宣布的那样，下一个月我们将进行期末考试。本题旨在考查定语从句，由句子结构来看，该从句为非限制性定语从句。句意中含有“正如，正像”这一意思，故应该用as 来引导。
答案：B
