語(yǔ)法易錯(cuò)點(diǎn)

1. a, an的選擇: 元音字母開(kāi)頭的單詞用an,輔音字母開(kāi)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(wèn)句和否定句用any.

6. 疑問(wèn)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(qián))

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(lái)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(xiě)最后的字母再加er,如big – bigger, thin – thinner ,hot – hotter

☆注意☆

比較的兩者應(yīng)該是互相對(duì)應(yīng)的可比較的東西.

典型錯(cuò)誤:My hair is longer than you.(我的頭發(fā)比你更長(zhǎng).)

比較的兩者是我的頭發(fā),你(整個(gè)人),那么比較的對(duì)象就沒(méi)有可比性.

應(yīng)該改為:My hair is longer than yours. 或My hair is longer than your hair.

動(dòng)詞過(guò)去式

動(dòng)詞的過(guò)去式的構(gòu)成規(guī)則有:

A,規(guī)則動(dòng)詞

① 一般直接在動(dòng)詞的后面加ed:如 worked , learned , cleaned , visited

② 以e結(jié)尾的動(dòng)詞直接加d:如 lived , danced , used

③ 以輔音字母加y結(jié)尾的動(dòng)詞要改y為i再加ed(此類動(dòng)詞較少)如 study – studied carry – carried worry – worried (注意play,stay不是輔音字母加y,所以不屬于此類)

④ 雙寫(xiě)最后一個(gè)字母(此類動(dòng)詞較少)如 stopped

B,不規(guī)則動(dòng)詞(此類詞并無(wú)規(guī)則,須熟記)小學(xué)階段要記住以下動(dòng)詞的原形和過(guò)去式:sing – sang , eat – ate , see – saw , have – had , do – did , go - went , take - took , buy - bought , get - got , read - read ,fly - flew , am/is - was ,

are - were , say - said , leave - left , swim - swam , tell - told , draw - drew , come - came , lose - lost , find - found , drink - drank , hurt - hurt , feel - felt
