一：学生易错词汇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：形容词比较级详解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 - funnier④ 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.比较级专项练习: 一、从方框中选出合适的单词完成句子?? heavy? tall? long? big(1) How?????????? is the Yellow River?(2) How?????????? is Mr Green??
