七年级知识点总结

初一英语基础知识点

一、48个国际音标及26个英文字母的正确书写

要熟练掌握元音和辅音，5个元音字母(a, e, i, o, u),字母的正确占格及单词间距。

二、be动词的用法

be动词有三种变形，分别是：am, is, are。记忆口诀：

“我”用am, “你”用are, is用于“他、她、它”;单数全都用is，复数全部都用are。

三、人称及人称代词的不同形式(主格和宾格)

1、三种人称：第一人称(I, we)，第二人称(you, you)，第三人称(he, she, it, Maria)。

2、人称代词的主格，即人称代词位于句子主语位置时的形态：I, We, You, You, He, She, It, Maria。

3、人称代词的宾格，即人称代词位于句子宾语位置时的形态：me, us, you, you, him, her, it。我爱（I）吃蜜（me），you不变；

he打招呼：“Hi,m”!

she去s，后加r；

It，it主宾同。

we宾好记勿忧思（us）；

they把y变成m。

4、形容词性物主代词：my, our, your, your, his, her, its, their。

5、名词性物主代词：mine, ours, yours, yours, his, hers, its, theirs。

名词性物主代词=形容词性物主代词+名词

Eg：--Whose pen is this?=Whose is this pen?

--It’s mine.=It’s my pen.

6、反身代词：myself, ourselves, yourself, yourselves, himself, herself, itself, themselves。

四、基数词(表示数量多少的词，大致相当于代数里的自然数) zero, one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen,

五、陈述句便一般疑问句、否定句和特殊疑问句

1.陈述句：主语+谓语动词（系动词、实意动词等）+其他

系动词：be、感官动词（look、sound、smell、taste、feel）

Eg:He is cool.

She feels better.

I read science books.

2.a.主语后是be动词或情态动词(can、could、may、might)或助动词will、would的陈述句变一般疑问句：直接将这些词提到句首；

Eg:This is my car. Is this my car?

He can play football. Can he play football.

b.主语后是实意动词的，如主语不是第三人称单数，直接在句首加Do；主语是第三人称单数，先在句首加Dose,再将实意动词的s去掉。

Eg:You work in an office. Do you work in an office?

Dose Sue spesk Eglish well?

3.a.主语后是be动词或情态动词(can、could、may、might)或助动词will、would的陈述句变一般疑问句：直接将这些词后加not；

He can’t sing.

b.主语后是实意动词的，如主语不是第三人称单数，直接在主语后加don’t；主语是第三人称单数，先在主语后加dosen’t,再将实意动词的s去掉。

She doesn’t watche TV every evening.

4.在一般疑问句前加上特殊疑问词或特殊疑问词词组，就是特殊疑问句。

Eg:What is it?

What color is it?
