来源:趣趣ABC少儿英语 时间:2019-05-27 16:03:07

   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
