多数形容词和副词有三个等级：原级、比较级和最高级。
本单元主要学习形容词、副词的原级和比较级的构成及其用法。
1. 同级比较
1. 表示两者在某一方面相同
This dress is as beautiful as that one.
Linda sings as well as Amy.
主语+ be / 行为动词+ as + 形容词 / 副词原形+ as +比较对象
Lily isn't as / so tall as me.
2. 表示一方在某一方面不及另一方时
I don't sing as / so loudly as my sister.
A+ be + not + as / so + 形容词原形+ as +B
A+ don’t / doesn’t / didn’t + 行为动词原形
+ as / so +副词原形+ as +B
It's too hot here.
3. 原级前可用very，quite，too等副词修饰。
I'm very hungry.
My sister runs quite fast.
4. as...as可表示“是……的几倍”或“是……的几分之几”。此时只需要在as...as前加上表示倍数的词（twice, three times...）或表示分数的词（half, a quarter...）。
Your dress is twice as expensive as mine.
你的衣服比我的贵一倍。
1. —Can your sister play ping-pong

表示“一方比另一方更……”

Who dances better, you or your sister
谁跳舞跳得更好，你还是你姐姐？
Who / Which / What + be + 形容词比较级, A or B
Who / Which / What + 行为动词 + 副词比较级, A or B
03 比较级的句型
（2）形容词和副词的比较级可以单独使用。

（6）than和as...as后所接代词或名词的正确形式

You are more outgoing than me. 你比我外向。
You are more outgoing than I am. 你比我外向。
