比较级的句式！
比较级用于二者的比较，其结构是：含有形容词比较级的主句+从属连词than 引导的从句（从句中常省去意义上和主句相同的部分）。比较级的常见句型及用法列举如下：
1、A + 动词+比较级 + than+ B . 表示“A比B更……”
如：I’m taller than you。
2、Which/Who+ 动词+比较级, A or B ? 表示“A和B哪一个更……？
如：Which is more delicious, hamburger or bread?
3、比较级+ and +比较级：表示“越来越……”
如：She becomes prettier and prettier。
注意：加more构成比较级的部分双音节词和多音节词，在表示“越来越……”时，其结构为：“more and more+形容词/ 副词原级”。
如：Lily is more and more beautiful。
4、the 比较级……，the 比较级……：表示“越……，越……”
如：The harder you learn, the better you understand。

比较级的变化规律
1、规则变化：由“原级+ -er”构成，-er读音为/ ə /
(1)一般直接在词尾加er。如 tall - taller；
(2) 以e结尾的，直接加r ，如 fine – finer ；
(3)以”辅音字母+y”结尾，改y为i再加er，如funny – funnier；
(4)以重读闭音节结尾，双写词尾辅音字母再加er，如big – bigger；
2、不规则变化：
（1）好good/ well—better
（2）坏bad/ badly—worse
（3）多many/ much—more
（4）少little—less
1.当as… as 中有名词时
as +形容词+ a +单数名词 /as + many/much +名词
This is as good an example as the other is.
I can carry as much paper as you can..
2. 倍数+ as + adj. + as= 倍数+ the+ of,表示倍数的词或其他程度副词做修饰语时放在as前
This room is twice as big as that one. (Your room is the same size as mine.)
This bridge is three times as long as that one. (This bridge is three times the length of that one. )
Your room is twice as large as mine.( Your room is twice the size of mine.)
3.可修饰比较级的词 a bit, a little, much, a lot, still, even,far等
4.many,old 和 far
1) 如果后接名词时, much more +不可数名词 ;many more +可数名词复数
2) old 有两种比较级和最高级形式: older/oldest 和elder/eldest,elder,eldest 只用于兄弟姐妹的长幼关系.My elder brother is an engineer.
3) far 有两种比较级,farther,further. 在英语中两者都可指距离.在美语中,father 表示距离,further表示进一步.I have nothing further to say.
5.the + 最高级 + 比较范围
The Sahara is the biggest desert in the world.
形容词最高级前通常必须用定冠词 the,副词最高级前可不用.
形容词most前面没有the,不表示最高级的含义,只表示"非常".
It is a most important problem. =It is a very important problem.
6．“the ＋ 形容词”的两种用法
“the＋形容词”既可以等同于复数普通名词,也可以等同于抽象名词,代表一类人或事.
The rich are apt to look down upon the poor.富人常常轻视穷人.
The poet had an yearning for the supernatural.诗人憧憬超自然的东西.
这种用法也可以适用于“the＋现在分词”及“the＋过去分词”.
The unexpected always happens. 天有不测风云.
The wounded and the dying were rushed to hospital. 受伤的人和垂死的人被急送到医院去了.
7. “the＋ 比较级＋理由”
该句型具有“更加”的意思.常以“all (或much) the＋ 比较级”的形式出现.例如：
I am the more inclined to help him because he is poor. 因为他穷,我更想帮他.
It is all the more dangerous for not being generally recognized as such.
一般不认为危险的,反而更加危险.
8.“the＋比较级...,the＋比较级...”.该句型的意思为“越……越……”.例如：
The more he flatters me,the less I like him.他越是迎合我,我越不喜欢他.
The higher the mountain is, the more people like to climb it; the more dangerous the mountain is, the more they wish to conquer it.山越高,人越想爬；山越危险,人越想征服它.
这种句型常用省略说法,The sooner,the better.越快越好. More haste,less speed. 欲速则不达.
9.“the last＋不定式/形容词从句”.意思是“最不大可能的、最不适的”.
Money is the last thing he wants, and you won’t succeed by offering it.
如果是比较3个音阶以上的形容词的话，前面加 more就行，比如A is more important than B
现在有三种常用的倍数表达法
例如：A是B的三倍长。
1. A is three as long as B.
2. A is three times longer than B.
3. A is three times the length of B.
as+原级＋as
as +adj.原级+ as possible/sb can
more than+复数
倍数表达法:
1.A+be+倍数+as+adj原级+as+B
2.A+be+倍数+adj比较级＋than+B
3.A+be+倍数+the+n.+of+B
4.The+n.+of+A+be+倍数+that+of+B
