形容词的比较级和最高级是如何构成的呢？
形容词的比较级和最高级在形式上有一定的变化规律，大体上分为规则变化和不规则变化两种。
一、形容词比较级和最高级的构成（规则变化）
1 大多数词后加-er/-est。
2 以不发音的字母e结尾的词后加-r/-st。
3 以“辅音字母+y”结尾的词，去掉y，再加-ier/-iest。
4 以一个辅音字母结尾的重读闭音节词，双写最后一个辅音字母，再加-er/-est。
5 多音节词和部分双音节词，在词前加mre/mst。
形容词比较级和最高级的构成（不规则变化）
有些形容词有两种比较级和最高级的变化方式。如：
handsmer/ mre handsme
handsmest/ mst handsme
pliter/ mre plite
plitest/ mst plite
simpler/ mre simple
simplest/ mst simple
stupider/ mre stupid
stupidest/ mst stupid
handsmeplitesimplestupid
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/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 /klɪərə/、clearest /klɪərɪst/。如果原级词末的发音为/ŋ/，加er 和est 时，/ŋ/音后得加上/g/音，如lng /lɒŋ/、lnger /lɒŋgə(r)/、lngest /lɒŋgɪst/。
二、形容词比较级常见用法如下：
1 通常情况下，我们用 “比较级 + than” 来引出比较的第二部分。
① This picture is mre beautiful than that ne.
这幅画比那幅画更漂亮。
② The white cat is fatter than the black cat.
2 我们常用“Which/Wh ... + 比较级，... r ” 的句型表示在两者中选择。
① Which picture is mre beautiful, this ne r that ne?
这幅画和那幅画，哪个更漂亮？
② Wh is yunger, Jhn r Jimmy?
约翰和吉米，谁更年轻？
3 我们可在比较级前加上a little、much、 even等词来表示程度。
① China is much larger than Japan.
② I am feeling even wrse tday.
③ The shes are a little bigger fr me.
这双鞋对我来说大一点。
4 我们用“比较级 + and + 比较级”的结构 来表示人或事物本身程度的改变，意 为“越……越……”。
① The bys are strnger and strnger.
② The cat is getting fatter and fatter.
这只猫变得越来越肥了。
1 我们用“the + 最高级 + 比较范围”的结 构来表示在某一范围内“最……”。
① I’m the tallest f/amng the three.
② Russia is the largest cuntry in the wrld.
俄罗斯是世界上最大的国家。
介词 f 和 amng后面接表示范围的人或物。
in后面接表示范围的名词或名词性短语。
二、形容词最高级常见用法如下：
2 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……”。 此时形容词的最高级前不需要定冠词the。
① Peter is his ldest sn.
② It was the exam paper f my wrst subject, histry.
那是一张历史试卷，历史是我最差的一门学科。
3 我们可以用序数词修饰形容词的最高级。
① Which river is the first lngest in the wrld?
世界第一长河是哪条河？
② In the USA, the secnd largest city is Ls Angeles.
美国的第二大城市是洛杉矶。
