高一英語必考知識(shí)點(diǎn)：it的用法
it的概念：
it可用作人稱代詞、指示代詞、先行詞及引導(dǎo)詞等。
it 的用法：
1、it可指天氣、溫度、時(shí)間、距離等 。
如：It is cold today, isn't it?
2、用作人稱代詞，代替前文提到過的事物。
如：The dog is not acold-blooded animals. It doesn't need to hibernate.
3、為避免重復(fù)，it可用來代替前面說過的短語或句子。
如：I tried to persuade my father to give up smoking, but found it impossible. (it=to persuade my father to give up smoking)
4、代替指示代詞this，that。
如：—What's this?
—It's an album.
—Whose new bike is that?
—It's Mary's.
注：it與one，that的區(qū)別：
it=the(this, that)+名詞，特指并且代替前面所提到的某特定事物。
如：He's bought a new car, so he drives it everywhere to show ito ff.
one=a+名詞，one指前面提到的同類事物中的不同的另一個(gè)。
如：He needs a computer, but he can't afford one.
that=the+名詞，that指代的名詞與前面的名詞屬于同一類，但不屬同一個(gè)。
如：The population of China is larger than that of Japan. that指代population，但其后有一個(gè)of短語作定語，以區(qū)別于the population of China。
注：it與that的異同：
it指同一事物，that指同類但并不是同一事物。
如：I like the climate of Kunming more than that of Beijing.
The climate of Kunming is mild, and I like it.
5、It/This/That+be+the first(second, third...) time+that-clause 這個(gè)句型表示截止到說話時(shí)為止的某人的一種經(jīng)歷，關(guān)鍵是注意time前有序數(shù)詞，主句是一般現(xiàn)在時(shí)is時(shí)，從句要用現(xiàn)在完成時(shí);如果主句用一般過去時(shí)was時(shí)，則從句須相應(yīng)地用過去完成時(shí)。
如：This is the first time(that) these Europeans have visited the Great Wall.
It was the fifth time(that) I had paid a friendly visit to America.
6、在一些相對(duì)固定的詞組中，沒有特殊含義，經(jīng)常不翻譯。
如：He's never really made it as an actor. 作為演員，他從未獲得過真正的成功。
It is my turn. 輪到我了。
強(qiáng)調(diào)句中的it：
可以用來改變句子結(jié)構(gòu)，使句子的某一成分得到強(qiáng)調(diào)：
1)強(qiáng)調(diào)句的基本句型it's/was+被強(qiáng)調(diào)成分+that/who+其他成分
原句：I told Jim the news in our office yesterday.
強(qiáng)調(diào)主語：It was I that/who told Jim the news in our office yesterday.
強(qiáng)調(diào)賓語：It was Jim that I told the news in our office yesterday.
或：It was the news that I told Jim in our office yesterday.
強(qiáng)調(diào)地點(diǎn)狀語：It was in our office that I told Jim the news yesterday.
強(qiáng)調(diào)時(shí)間狀語：It was yesterday that I told Jim the news in our office.
2)強(qiáng)調(diào)句的一般疑問句型Is/Was+it+所強(qiáng)調(diào)部分+that/who...?
如：Was it you that told Jim the news in your office yesterday?
3)強(qiáng)調(diào)句的特殊疑問句型疑問詞+is/was+it+that/who...?
如：Who was it that told Jim the news in your office yesterday?
【注】強(qiáng)調(diào)句與主語從句雖然在形式上很相似，即都含有it is(was)...that。但，區(qū)別在于：強(qiáng)調(diào)句去掉it is(was)…that之后，句子結(jié)構(gòu)仍然完整，而主語從句卻不能這樣。
如：(It is)our hope(that) the two sides will work towards peace.
解析：去掉It is…that之后，句子是不成立的。由此得出該句不是強(qiáng)調(diào)句，而是一個(gè)簡(jiǎn)單的主語從句，it是形式主語，從句是真正的主語。
