构成形容词比较级和最高级的er和est,自成一个音节,读作/ə(r)/ 和/ɪst/。如果原级词末为不发音的字母 r,加er和est 时,r 要发/r/ 音,如clear /klɪə(r)/、clearer /ˈklɪərə(r)/、clearest /ˈklɪərɪst/。如果原级词末的发音为/ŋ/,加er 和est 时,/ŋ/音后得加上/ɡ/音,如 long /lɒŋ/、longer /ˈlɒŋɡə(r)/、longest /ˈlɒŋɡɪst/。

这幅画比那幅画更漂亮。
2. 我们常用“which/who ... + 比较级 , A or B?”的句型来表示在A 和B二者中做选择。
e.g. Which picture is more beautiful, this one or that one?
这幅画和那幅画,哪个更漂亮?
Who is ____________(careful), Amy or Sandy?

e.g. China is much larger than Japan.

5. 我们用“the+比较级,the +比较级”来表示“越...就越...”。
e.g. The more we get together, the happier we will be.
我们越在一起,我们将就越开心。
6. 我们用比较级表示最高级含义,can’t/couldn’t+ 比较级表示“再…… 不过了”。

形容词最高级常见用法
2. 我们可以用序数词修饰形容词的最高级。
1. 我们用“形容词性物主代词 + 最高级”的结构来表示某人或事物的“最……”。
e.g. Peter is his oldest son. 彼得是他的长子。
注意:此时形容词的最高级前不需要加定冠词the。
e.g. In the USA, the second largest city is Los Angeles.
美国的第二大城市是洛杉矶。
