初一英語(yǔ)知識(shí)點(diǎn)梳理

初一英語(yǔ)的知識(shí)點(diǎn)很細(xì)，一個(gè)單詞、一個(gè)詞組或許就包含著一個(gè)知識(shí)點(diǎn)，更何況還有那么多的句式和語(yǔ)法。下面小編整理了初一英語(yǔ)知識(shí)點(diǎn)，希望能對(duì)大家的初一英語(yǔ)學(xué)習(xí)有所幫助。

人稱及人稱代詞的不同形式

1、三種人稱：第一人稱(I,we)，第二人稱(you,you)，第三人稱(he,she,it,Maria)。

2、人稱代詞的賓格，即人稱代詞位于句子賓語(yǔ)位置時(shí)的形態(tài)：me,us,you,you,him,her,it。

3、形容詞性物主代詞：my,our,your,your,his,her,its,their。

4、名詞性物主代詞：mine,ours,yours,yours,his,hers,its,theirs。

this，that和it用法

(1)this和that是指示代詞，it是人稱代詞。

(2)距離說(shuō)話人近的人或物用this,距離說(shuō)話人遠(yuǎn)的人或物用that。如：

This is a flower. 這是一朵花。(近處)

That is a tree. 那是一棵樹。(遠(yuǎn)處)

(3)放在一起的兩樣?xùn)|西，先說(shuō)this, 后說(shuō)that。如：

This is a pen. That is a pencil. 這是一支鋼筆。那是一支鉛筆。

(4)向別人介紹某人時(shí)說(shuō)This is…, 不說(shuō)That is…。如：

This is Helen. Helen, this is Tom. 這是海倫。海倫，這是湯姆。

(5)This is 不能縮寫, 而That is可以縮寫。如：

This is a bike. That’s a car. 這是一輛自行車。那是一輛轎車。

(6)打電話時(shí)，介紹自己用this, 詢問(wèn)對(duì)方用that。如：

—Hello! Is that Miss Green? 喂，是格林小姐嗎？

—Yes, this is. Who’s that? 是的，我是，你是誰(shuí)？

注意：雖然漢語(yǔ)中使用“我”和“你”，但英語(yǔ)中打電話時(shí)絕不可以說(shuō)：

I am…, Are you…？/Whoare you?

(7)在回答this或that作主語(yǔ)的疑問(wèn)句時(shí), 要用it代替this或that。如：

①—Is this a notebook? 這是筆記本嗎？

—Yes, it is. 是的，它是。

②—What’s that? 那是什么？

—It’s a kite. 是只風(fēng)箏。

句子單數(shù)變復(fù)數(shù)

(1)主格人稱代詞要變成相應(yīng)的復(fù)數(shù)主格人稱代詞,即I→we,you→you，she,he,it→they。如：

She is a girl. →They are girls.

(2)am，is要變?yōu)閍re。如：

I’m a student. →Weare students.

(3)不定冠詞a，an要去掉。如：

He is a boy. →They are boys.

(4)普通單數(shù)名詞要變?yōu)閺?fù)數(shù)形式。如：

It is an apple. →They are apples.

(5)指示代詞this，that要變?yōu)閠hese，those。如：

This is a box. →These are boxes.
