1、比较级用法:
表示比…更,用比较级形容词+than+比较成分,than后主词的述语动词往往省略,非正式用法的than后的人称代名词可用受格。
表示较…低; 不及…用less+原级形容词+than+比较成分。
表示两者之中较…,用the+比较级+of the two。
定冠词或指示形容词+比较级+名词表示比较。
有少数以ior结尾的形容词,如inferior(次于),junior(年幼的;下级的),posterior(之后),prior(之前),senior(年长的,上级的),superior(优于)等本身就有比较的意思,常与介系词to连用。
比较形容词可以被副词如a little(一点),much(得多),even(更加),still(更加),far(…的多)等修饰,但不可用very修饰。
2、比较级的句型:
同级比较:
由“...as + 形容词原型 + as...”或“...as + 形容词 + 名词 + as...”构成。My grandpa is as energetic as a young man.Exercise is as useful a way as any other to lose unwanted weight.I try to find as much information as I can about what happened.
由“...not so (as) + 形容词或副词原型 + as...”或“...not so (as) + 形容词 + 名词 + as...”构成。Luckily, the weather is not so wet as it is today.
降级比较:
由“……形容词比较级+ than...”构成。He is more concerned about others than about himself.
由“...many / much more + 可数 / 不可数名词 + than...”My friend earned much more money than I did last year.
