初一英语语法知识点总结复习

　　一. 动词be(am,is,are)的用法：

　　be动词包括“am”, “is”, “are”三种形式。

　　①第一人称单数(I)配合am来用。句型解析析：I am+…

　　例句：I am Snoopy.

　　I am ten years old.

　　I am a student.

　　I am a boy.

　　②第二人称(You)配合are使用。句型解析：You are+…

　　例句：You are my good friend.

　　You are a good teacher.

　　You are beautiful

　　③第三人称单数(He or She or It)配合is使用。句型解析：She(He, It) is +……

　　例句：She is a good girl.

　　She is so tall.

　　She is short.

　　④人称复数 (we /you/they)配合are使用。句型解析：We (You, They) are +……

　　例句We are in Class 5,Grade 7.

　　They are my friends.

　　You are good students.

　　用法口诀：

　　我(I)用am, 你(you)用are，is跟着他(he)，她(she)，它(it)。单数名词用is，复数名词全用are。变否定，更容易，be后not加上去。变疑问，往前提，句末问号莫丢弃。还有一条须注意，句首大写莫忘记。

　　对应练习：

　　二、人称代词

　　表示“我”、“你”、“他”、“她”、“它”、“我们”、“你们”、“他们”的词，叫做人称代词。人称代词有人称、数和格的变化，见下表：

　　人称代词主格：作主语，表示谁怎么样了、干什么了。

　　I am a teacher. You are student. He is a student, too.

　　We/You/They are students.

　　人称代词宾格作宾语，表示动作行为的对象。

　　Give it to me. Let’s go (let’s =let us)

　　三、物主代词

　　表示所有关系的代词叫做物主代词，也可叫做代词所有格。物主代词分形容词性物主代词和名词性物主代词二种，其人称和数的变化见下表。

　　形容词性物主代词(my/your/his/her/its/our/their)+名词

　　而名词性物主代词则相当于形容词性物主代词+名词,故其后不必加名词。如：

　　Is this your book?

　　No,，it isn’t， it’s hers(her book)

　　This pen is mine.
