一、be动词
(verb to be 动词be是初中最先接触到的动词，有am are is I am, you are, he is , she is , it is (not a ...student. We are ,you are ,they are (not students. are not=aren't is not =isn't 肯定与否定的回答形式
Am I ...? Yes,you are. No,you are not. Are you ...? Yes,I am.
No,I am not. Is he(she ,it ...? Yes,he (she, it is . No,he(she,it isn't. Are you (they ... ? Yes,we( they are. No,we ( they are not.
二、人称代词和物主代词 (personal and possessive pronouns 主格和宾格，主格是动作的发生这做主语，宾格是动作的承受者作宾语或者谓语介词后做介词的补语
主格： I you she he it we you they 宾格： me you her him it us you them I am learning English. They are picking apples. We will help them. Some of us are tall. 下面讲讲物主代词，表示物主关系的代词，也叫人称代词的所有格，分为形容词型物主代词和名词性物主代词，形容词型物主代词在名词前做定语起修饰的作用，名词性物主代词可以
在句中独立做主语宾语，相当于形容词型物主代词加上后面的宾语 形容词型物主代词有
my your her his its our your their 名词性物主代词
mine yours hers his its ours yours theirs
My hat Their classroom our school 分别修饰后面的名词 This is not my coat. Mine is in the bedroom. You may use my bike. I'll use his. (his 相当于名词性物主代词做宾语）
The shoes are theirs. 这句中theirs是名词性物主代词做表语相当于their shoes He is a friend of mine. 和介词连用 of mine 构成定语修饰friend 记住不同人称的主格和宾格，名词性与形容词性的形式 不要死记硬背，要多练，多说，注意英汉两种语言中物主代词的不同用法，表示某物属于某人的时候通常用物主代词，但是翻译成汉语的时候时常省略
Now the girl is quite a help to her mother. 现在这个女孩是他妈妈的得力助手
He writes with his left hand. 三、There be 句型
There is (are + 某物或某人在某地 “某地有某物 （某人）”
要注意be动词单复数要跟后面的名词一致
There is a house in picture. There are some birds in the tree. There isn't a house in the house. There isn't any water in the bottle. There aren't any factories in the city. Is there a boy under the tree? Yes,there is . No,there isn't. Are there any bananas on the tree? Yes,there are(some.
No,there aren't(any. 注意：表示某物某地有某人的时候只表示客观存在的东西，不表示某人拥有某物 There are five pictures on the wall. 表示客观存在 I have five pictures. 表示某人拥有某东西 There be 中的现在完成时
There has been a picture on the wall for a long time. The picture has been on the wall for a long time . 两种或两种以上时名词候，be单复数就近原则 肯定句中and连接，否定句中用or连接 There is an apple and some tomatoes on the table. There are two balls and a box under the table. There isn't a desk or chairs in the classroom. There aren't any pictures or a map on the wall.
四、名词的复数形式(the plurals of nouns 英语中的名词可分为可数名词和不可数名词，可数名词是有复数的 An apple -- two apples
a book -- two books 不可数名词一般是么有复数形式的，但是表示多的意思的话，表示复数的意义，就要在前面加上一些单位词
Bread -- some pieces of bread Water -- three glasses of water 可数名词单数到复数的变化
1,大部分名词的复数形式是在单数形式后加s Book -- books page -- pages 2,s,x,,ch,sh,结尾的名词加es
