规则变化：单音节和部分双音节词一般在词尾加-ertall→tallerlong→longer以字母e结尾的词，在词尾加-rfine→finerlate→later重读闭音节词且词尾只有一个辅音字母，双写辅音字母再加-erbig→biggerthin→thinner

以“辅音字母

+

y”结尾的双音节词，先把“y”改为“i”再加-er

easy→easier

friendly→friendlier比较级的句子结构：原来的句子结构不变，只是将形容词变成比较级的形式，然后在后面用than引出所比较的对象。例如：1.Shanghaiisbusy.ShanghaiisbusierthanHangzhou.2.Shanghaiisanoldcity.ShanghaiisanoldercitythanShenzhen.比较级常用句型：1.
