主要知識(shí)點(diǎn)如下：

一、語(yǔ)法易錯(cuò)點(diǎn)

1. a, an的選擇: 元音字母開頭的單詞用an,輔音字母開頭的單詞用a. 2. am , is , are的選擇: 單數(shù)用is , 復(fù)數(shù)用are. I 用 am , you 用 are. 3. have , has 的選擇: 表示某人有某物.單數(shù)用has , 復(fù)數(shù)用have. I ,you 用 have . 4. there is, there are 的選擇:表示某地有某物,某人.單數(shù)用there is , 復(fù)數(shù)用there are. 5. some, any 的選擇:肯定句用some, 疑問句和否定句用any. 6. 疑問詞的選擇:what (什么) who (誰(shuí)) where (哪里) whose (誰(shuí)的) why(為什么)when(什么時(shí)候)which(哪一個(gè))how old (多大) how many (多少)how much(多少錢) 

二:形容詞比較級(jí)

當(dāng)我們需要對(duì)事物作出比較時(shí),需要用到比較級(jí).比較級(jí)的句子結(jié)構(gòu)通常是: 

什么 + 動(dòng)詞be (am , is , are ) + 形容詞比較級(jí) + 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.)

 形容詞的比較級(jí)是在形容詞的基礎(chǔ)上變化而來的,它的變化規(guī)則是: ① 一般的直接在詞尾加er ,如 tall - taller , strong - stronger , ② 以e結(jié)尾的,直接加r ,如 fine – finer , ③ 以輔音字母加y結(jié)尾的,先改y為i再加er,如funny - funnier ④ 雙寫最后的字母再加er,如big – bigger, thin – thinner ,hot – hotter 

Eg :I have a new car.( I 主格)

Excuse me (me 賓格)

I ask him to go (him 賓格)

They sit in front of me (me 賓格)

主格(8個(gè))：I 我you你 he他 she她 it它 we 我們you 你們they他(她、它)們

賓格(8個(gè))：me我 you你 him 他her她 it它 us我們 you你們 them他(她、它)們

六:句型專項(xiàng)歸類

1.肯定句:是指用肯定的語(yǔ)氣來陳述的句子,

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:含有否定詞或表示否定意義詞的句子,

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. 

3,一般疑問句:是指詢問事實(shí)的句子,此類句子必須用"yes",或"no"來回答. 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。
