2.形容词不规则变化:
3. 其他双音节词或多音节词，在该词前面加mre / mst。
例如：beautiful→mre beautiful→mst beautiful;
useful→mre useful→mst useful
二、形容词比较级和最高级的用法和常用结构
1. 比较级
两个人或两种事物比较时，用比较级。常见结构为：A + be +形容词比较级+ than +B。例如：
I am taller than yu. 我比你高。
Pasta is mre delicius than pizza. 意大利面比披萨更好吃。
主语+谓语动词+比较级+than any ther+单数名词（+介词短语）＂表示＂比其他的任何……都……
如：He is better than any ther student in the class. 他比班里其他任何一个学生都好
主语+谓语+the+形容词比较级+f the tw...是两者中较...的
Lk at the tw bys,my yunger brther is the taller f the tw.
看那两个男孩，我弟弟是两个当中较高的那个.
“the+比较级…,the+比较级…”表示“越…就越…”。
The mre trees we plant,the better it will be.(我们栽的树越多,情况就会越好)
“疑问词+谓语+形容词比较级，Ar B?”A与B，...更表示两者之间的选择
Which is bigger,the earth r the mn?地球和月球，哪一个更大？
甲+be+倍数+形容词的比较级+than+乙？甲是乙的几倍..?
This classrm is fur times bigger than that ne?这间教室是那间教室的四倍大.
注意：①形容词比较级前可以用a lt，much，far，even，still 和a little等表示程度的词语修饰。
例如：He made much fewer mistakes than I did.他比我犯的错误少得多。
He is even richer than me. 他甚至比我还富有。
② 主语(第一个人物) + 谓语动词(否定式) + as / s + 形容词/副词原级 + as + 第二个人物+….
He is nt s / as excited as his yunger sister.(他没他妹妹那么兴奋)
Lily did nt ride her bike s / as slwly as an ld lady. (莉莉骑车不像老太太那样慢)
③在两者进行比较时，为了避免重复出现前面的名词，一般常用替代词代替
that:替代than之前出现“the+可数名词单数/the+不可数名词”
The cst f living in Shenzhen is higher than that f living in Shenyang.
在深圳的生活费用比沈阳高。
thse：替代than之前出现的the+可数名词复数

Pasta is the mst delicius f the three kinds f fds.在这三种食物中，意大利面是最好吃的。

疑问词+谓语+the+形容词的最高级+甲，乙r 丙？甲乙丙，...最
Which cuntry is the largest,China,Brazil r Canada?

注意：形容词最高级前一般要加定冠词the,但当形容词最高级前有形容词性物主代词，指示代词或名词所有格修饰时，用不定冠词the
