人教版八下英语Unit 7 单元语法知识梳理
一、形容词、副词的比较级和最高级1.概述：英语中的形容词和副词有三个等级，即原级、比较级和最高级。
比较级主要用于两者之间作比较，最高级主要用于三者或三者以上进行比较。
2.比较等级的构成：（1）规则变化①一般在词尾直接加-er或-est，如：tall—taller—tallest，long—longer—longest②以不发音的字母e结尾的单词在词尾直接加-r或-st，如，nice—nicer—nicest③以“辅音字母+y结尾”的词，把y变为i，再加-er或-est，如，heavy—heavier—heaviest④重读闭音节，末尾只有一个辅音字母，先双写这个辅音字母，再加er或-est，如：big—bigger—biggest⑤部分双音节词和多音节词分别在原级前加more构成比较级和most构成最高级，如：slowly—more slowly—most slowly；beautiful—more beautiful—most beautiful比较等级的变化口诀比较等级要变化，一般词尾加-er(-est)。
词尾若有哑音e，直接加-r(-st)就可以。
一辅重读闭音节，辅音字母要双写。
辅音字母加y 结尾，要把y改i加-er(-est)。
（2）不规则变化原级比较级最高级good/ well better best bad/ ill worse worstmany/ much more most little less leastold older（新旧或年龄）/elder（兄弟姐妹的长幼关系）oldest/eldestfar farther（表示距离，译为“更远”）/further（表示程度，译为“进一步的”）farthest/furthest不规则变化口诀：合二为一共三对：“坏（bad）、病(ill)”“两多(many, much)”并“两好(good, well)”；一分为二有两个，一是“远(far)”来二是“老(old)”；只有一词含双义，只记“少（little）”来不记“小”。
