多音节词和部分双音节词
以字母e结尾的词，在词尾加-r
以“辅音字母+y”结尾的双音节词，变y为i，再加-er
重读闭音节词尾只有一个辅音字母时，先双写该辅音字母，再加-er
tall→taller fast→faster
large→larger nice→nicer
lazy→lazier early→earlier
big→biggerfat→fatter
utging→ mre utgingclurful→ mre clurful
形容词和副词的比较级的构成
比较级要变化，一般词尾加­er。词尾若有哑音e，直接加r就可以。辅音字母若加y, 记得变y为i。一辅重读闭音节，末尾字母要双写。多、双音节有规律，词前加mre就可以。

大多数形容词和副词有三个等级：原级、比较级和最高级。比较级表示“更……”，用于两者之间的比较，说明“前者比后者更……”。
Tm is taller than me.
Tm runs faster than me (d).
Tips: than前后所使用的动词相同时，通常用助动词代替后面的动词或省略后面的动词。
Grammar Fcus
1. A + be + 形容词比较级 + than + B
e.g. I’m mre utging than yu.
一、高级：两者进行比较,表示“一方比另一方更”
2. A + 实义动词 + 副词比较级 + than + B
e.g. Tm jumps higher than Jack.
1. A + be + as +形容词原级 + as + B
e.g. Jack is as funny as Mike.
e.g. Mike gets up as early as Sue.
二、同级: 两者进行比较,表示“一方与另一方一样”
2. A + 实义动词 + as +adv.原级+as + B
迈克尔与休起得一样早。
两个 as 之间原，比较级后常接than。
三、低级：两者进行比较,表示“一方不如另一方”
1. A + 谓语 + nt as(s) + adj./adv.原级 + as + B.
Mike is nt as(s) serius as Tm.
Tm desn't sing as(s) well as Jim.
2. A + 谓语v. + less + adj./adv.原级 + than + B.
I am less hard-wrking than my sister.
Dad speaks less ludly than grandpa.
四、超级:比较级之前可以用much, a lt, a little, a bit, even等词来修饰，表示程度。 1. much/a lt/ far +比较级, 表示 “得多” This city is much mre beautiful than befre. 这个城市比以前更漂亮了。 2. a bit/a little +比较级，表示 “...一点儿”。 She’s a little mre utging than me. 她比我开朗一些。 3. even / still / yet + 比较级，表示 “甚至”。 This time he did it even better. 这次他做得还要好.
much/a lt /far+比较级…得多 a little/a bit+比较级 …稍微，一些even+比较级 …更……still +比较级 …(仍然)更,还要…
very/quite/s /as/t/really+原级
【拓展】 比较级前还可用“数词 + 名词 ”构成的短语来修饰。
He is three years lder than I (am) .他比我大三岁 。He is tw inches taller than his father .他比他父亲高二英寸。My rm is twice bigger than yurs .我的房间比你的大两倍 。
1. 单音节形容词或副词：~ +er + and + ~ +er healthier and healthier better and better e.g. The earth is getting warmer and warmer . 2. 多音节形容词或副词：mre and mre + 原级 mre and mre beautiful eg: Talent shws are getting mre and mre ppular.
五、不断升级：两个相同的比较级用and来连接，表 示“越来越”。
六、相伴升级：后者随前者的变化而变化，意为 “ 越... , 就越... 。 “ The+比较级+主语+谓语, the+比较级+主语+谓语”e.g. The harder yu study, the better yur grades will be. 你越努力学习，你的成绩越好。 The mre yu read,the better yu understand.    你看的书越多，你懂得就越多。 前者相当于一个条件句，因此要用一般现在时态代替一般将来时。
（1）“Which / Wh is + 比较级…？”比较A、B两事物，问其中哪一个较……时，用此句型。如：Which T-shirt is nicer, this ne r that ne? 这件和那件，哪一件T恤更好？ Wh is mre active, Mary r Kate? 玛丽和凯特，谁更加活泼？
【注意区别】 Wh is taller , Lily r Lucy? Wh is the taller girl, Lily r Lucy? Which is larger , Beijing r Shanghai? Which is the larger city, Beijing r Shanghai?
（2）the + 比较级 + f the tw 表示“两者中较...的那个人或物”，此时比较级后的名词表特指，故加the。 He is the taller (ne) f the tw brthers . Taipei is the bigger (ne) f the tw cities . She is the mre beautiful (ne) f the tw sisters . 此时的冠词不是修饰比较级，而是修饰其后的名词 或代词ne。
（3）排除问题，比较级结构表示最高级含义。（初步了解）
A+ …+比较级+ than+any ther +单数名词
A+ …+比较级+ than+the ther +复数名词
A+ …+比较级+ than+the thers
A比其它… A是最……，表示最高级的意思。
注意：当A在比较的另一方里面时，需要排除；当 A不在比较的另一方里面时，不需要排除。
