问一下英语语法单词中的比较级和最高级如何变？？？？

首先，涉及比较级和最高级的单词的词只有两种。形容词和副词。
有很多这样的词，所以恕我不能一一列举，但可以告诉你它们的变化规则。
比较级和最高级的变化有两种，1、规则变化（记住规则）。2、不规则变化（记住这几个词）
一、规则变化（分两种情况）
（一）：单音节或部分双音节的词的比较级和最高级的变法:
1.一般情况下直接加er或est.
如:short→shorter→shortest
2.以字母e结尾的形容词和副词加r或st
如:nice→nicer→nicest
3.以辅音字母y结尾的Y改为I加er,est
如:happy→happier→happiest
4.重读闭音节结尾的双写结尾辅音字母加er或est
如:fat→fatter→fattest
（二）：多音节的形容词和副词的比较级和最高级.
比较级在形容词和副词前面加more,最高级在形容词和副词前面加most.
如:beautiful→more beautiful→most beautiful
(而且在句子中,形容词最高级前必须加the。副词最高级前则可省略the)
二、不规则变化（记住这几个词）
good/well→better→best
many/much→more→most
ill/bad(badly)→worse→worst
little→less→least
old(eld)→older→oldest(elder/eldest)
far→farther→farthest(further/furthest)
三、关于查字典
所有的词后都有词性说明符号，你要记住adj表示该词是形容词，adv表示该词是副词。
希望对你有帮助。

2．A+V. not+as+a.∕ad.（原级）+as+B. （not as…as… 不像…一样）

例句：This tree isn’t as big as that one. 这棵树不和那棵一样大。
Tom doesn’t run as fast as Jack. 汤姆跑的不像杰克一样快。
Tom doesn’t run so fast as Jack. 汤姆跑的不像杰克一样快。

5．比较级+and+比较级→越来越…
例：fatter and fatter 越来越胖
bigger and bigger 越来越大
more and more 越来越多
6．※The+比较级+…（主+谓），the+比较级+…（主+谓） 越…越…（通常为省略句）
例句：The more, the better. 越多越好。
