语法 Grammar in use——形容词的比较级和最高级 （1）构成
A 大多数单音节形容词的比较级和最高级的构成是在其原级后面加上-er和-est：
small----smaller----smallest new----newer----newest B 许多单音节形容词只有一个元音字母，其末尾为一辅音字母。在比较级和最高级形式中，这个辅音字母要双写：
big----bigger----biggest thin----thinner----thinnest C 许多单音节形容词以-e结尾，如 nice。这些形容词只需在原级形式后加-r和-st：
large----larger----largest nice----nicer----nicest D 有些形容词以-y结尾，而在-y前是一个辅音字母。这些形容词一般有两个音节。变为比较级和最高级时，-y要变成-i，末尾再加-er和-est：
easy----easier----easiest heavy----heavier----heaviest E 但有少数形容词的比较级和最高级是不规则的，必须熟记，如： good----better----best bad----worse----worst F 大多数较长的形容词（即有两个以上音节的词）可与more连用构成其比较级形式，与most连用构成其最高级形式。
