一、形容词、副词比较级的构成：规则变化1.单音节词和部分少数以-er, -w结尾的双音节词在词尾直接加-er，如：tall—taller 2.以不发音e结尾的单音节词，只加-r，如： nice—nicer 3.以辅音字母加y结尾的双音节词，把y变i再加-er，如：happy—happier 4.以重读闭音节结尾，并且末尾只有一个辅音字母的，双写词尾字母再加-er，如：thin—thinner5.其它双音节词或多音节词，在该词前面加-mre，如：beautiful—mre beautiful
不规则变化:gd/well — better bad/badly — wrse many/much — mre little — less far — farther/further

注意事项1. 修饰比较级的词：much, even, still, a little, far, a lt, a bit；修饰原级：very, s, t, quite 。2. 在比较等级中，比较的对象必须是同类事物，即人与人比较，物与物比较。His ruler is lnger than mine.3. 要合乎逻辑：不能自己和自己比较，为避免错误用any ther+单数名词。China is larger than any ther cuntry in Asia.
