二:形容词比较级详解
当我们需要对事物作出比较时,:
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.
