​小学英语100分，小学英语考试易错知识点汇总！学霸必备！

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 

☆注意☆  

比较的两者应该是互相对应的可比较的东西. 

典型错误:My hair is longer than you.(我的头发比你更长.) 

比较的两者是我的头发,你(整个人),那么比较的对象就没有可比性. 

应该改为:My hair is longer than yours. 或My hair is longer than your hair. 

三:动词过去式

动词的过去式的构成规则有:

A,规则动词 

① 一般直接在动词的后面加ed:如 worked , learned , cleaned , visited 

② 以e结尾的动词直接加d:如 lived , danced , used 

③ 以辅音字母加y结尾的动词要改y为i再加ed(此类动词较少)如 study – studied carry – carried worry – worried (注意play,stay不是辅音字母加y,所以不属于此类) 

④ 双写最后一个字母(此类动词较少)如 stopped 

B,不规则动词(此类词并无规则,须熟记)小学阶段要记住以下动词的原形和过去式: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
