高一是初高中的過(guò)渡時(shí)期,在高中的起始階段對(duì)學(xué)生英語(yǔ)聽(tīng)力能力培養(yǎng)的重要性具有非凡的意義。高一英語(yǔ)有哪些必考知識(shí)點(diǎn)呢?接下來(lái)學(xué)習(xí)啦小編為你整理了高一英語(yǔ)必考知識(shí)點(diǎn)，一起來(lái)看看吧。

　　高一英語(yǔ)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(guò)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(lái)代替前面說(shuō)過(guò)的短語(yǔ)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(yǔ)作定語(yǔ)，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(shuō)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(guò)去時(shí)was時(shí)，則從句須相應(yīng)地用過(guò)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(méi)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(guò)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(lái)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(yǔ)：It was I that/who told Jim the news in our office yesterday.

　　強(qiáng)調(diào)賓語(yǔ)：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(yǔ)：It was in our office that I told Jim the news yesterday.

　　強(qiáng)調(diào)時(shí)間狀語(yǔ)：It was yesterday that I told Jim the news in our office.

　　2)強(qiáng)調(diào)句的一般疑問(wèn)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(wèn)句型疑問(wèn)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(yǔ)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(yǔ)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(yǔ)從句，it是形式主語(yǔ)，從句是真正的主語(yǔ)。
