2 比较级的表示法:主语+be+比较级+than…
主语+谓语+比较级+than…
1)不同主语的比较,
①双方比较,表示一方超过另一方时,用"比较级十 than"的结构表示
He is two years younger than I.
②表示一方不及另一方时,用" less十原级十 than"的结构表示

2) 同一主语不同方面的比较
She is now happier than she has ever been
用于修饰比较级的词:even, (very)much, far, a lot, still, yet. a bit,alittle,still,much,yet,by far
注意:byfar通常用于强调最高级.用于比较级时,一般放在比较级的后面,如在前面,应在二者中间加"the".如

He is by far the taller of the two brothers.
表示一方超过另一方的程度或数量,可在比较级前加上上述表示程度的副词,以加强语气。
He works even harder than before.
4)某些以一 or结尾的形容词进行比较时,用 to代替 than.(这些词有inferior [in'fiəriə]低人一等的| 下等的 | 下级的, superior[sju:'piriə]上级的;优秀的,出众的;高傲的,junior(下级的,年少的),senior(年长的,高级的),prior(较早的,在先的)等.Juniorschool小学,senior school中学例如:

5)在比较从句中为了避免重复,我们通常用 that(those),one(ones)代替前面出现的名词。that指物,one既可指人,也可指物.that可代替可数名词单数和不可数名词,而one只能代替可数名词.例如:
