主要知识点如下：
一、语法易错点
1. a, an的选择: 元音字母开头的单词用an,辅音字母开头的单词用a. 2. am , is , are的选择: 单数用is , 复数用are. I 用 am , you 用 are. 3. have , has 的选择: 表示某人有某物.单数用has , 复数用have. I ,you 用 have . 4. there is, there are 的选择:表示某地有某物,某人.单数用there is , 复数用there are. 5. some, any 的选择:肯定句用some, 疑问句和否定句用any. 6. 疑问词的选择:what (什么) who (谁) where (哪里) whose (谁的) why(为什么)when(什么时候)which(哪一个)how old (多大) how many (多少)how much(多少钱)
二:形容词比较级
当我们需要对事物作出比较时,需要用到比较级.比较级的句子结构通常是:
什么 + 动词be (am , is , are ) + 形容词比较级 + than(比)+ 什么 ,如:
I'm taller and heavier than you. (我比你更高和更重.) An elephant is bigger than a tiger. (一只大象比一只老虎更大.)
形容词的比较级是在形容词的基础上变化而来的,它的变化规则是: ① 一般的直接在词尾加er ,如 tall - taller , strong - stronger , ② 以e结尾的,直接加r ,如 fine – finer , ③ 以辅音字母加y结尾的,先改y为i再加er,如funny - funnier ④ 双写最后的字母再加er,如big – bigger, thin – thinner ,hot – hotter
Eg :I have a new car.( I 主格)
Excuse me (me 宾格)
I ask him to go (him 宾格)
They sit in front of me (me 宾格)
主格(8个)：I 我you你 he他 she她 it它 we 我们you 你们they他(她、它)们
宾格(8个)：me我 you你 him 他her她 it它 us我们 you你们 them他(她、它)们
六:句型专项归类
1.肯定句:是指用肯定的语气来陈述的句子,
如:I'm a student.
She is a doctor.
He works in a hospital. There are four fans in our classroom.2,否定句:含有否定词或表示否定意义词的句子,
如:I'm not a student.He does not (doesn't) work in a hospital.
There are not (aren't) four fans in our classroom.
3,一般疑问句:是指询问事实的句子,此类句子必须用"yes",或"no"来回答. 如:Are you a student ？Yes, I am No, I'm not.Is she a doctor？Yes, she is. No, she isn't.Does he work in a hospital ？Yes, he does. / No, he doesn't.Did you watch TV yesterday evening? Yes, I did. / No, I didn't. 等等。
