1、形容词副词级别变化规则形容词副词的级别变化知识精讲大多数形容词和副词有比较级和最高级的变化，及原级、比较级和最高级。用来表示事物的等级差别，原级即形容词或副词的原形，比较级和最高级有规则变化和不规则变化两种，详见下表：1. 规则变化类别构成方法原级比较级最高级单音节词和部分双音节词一般的在词尾直接加-er/ -estlongtalllongertallerlongesttallest以不发音的字母e结尾直接加-r/-stlatelargelaterlargerlatestlargest以辅音字母+y结尾的双音节词，变y为i ,再加-er/-esteasyhappyheavyeasierhapp

4、错点：掌握形容词比较级和最高级的变化规则，熟记少数特殊的不规则变化。构成比较级和最高级有两种方式：一是在词尾加-er构成比较级，加-est构成最高级；另一种形式是在词前加more构成比较级，加(the) most 构成最高级。三、补充点：1. farther, further这两个词都是far的比较级形式，但在用法上有所区别：1). farther和further都可指具体的距离，即空间时间上的“较远”。如： Lets not go any farther/further.我们别再走了吧。 The service desk is at the farther/further end of th
5、e hall.咨询处在大厅稍往里的地方。2). further还可用于抽象的引申义，如时间，程度和数量等，表示“进一步，更进一层”，此时，不能用farther。如： I may be able to give you some further information about it.关于这个问题，我还可以给你一些信息。 The problem will be further discussed at the class meeting.这个问题在班会上还将进一步讨论。 2. older和elder这两个词均是old的比较级，但在用法上有所区别：1). elder表示“前辈的”、“年纪较长的”
6、，仅用于同一家庭成员的比较；older则不限于此。例如：My younger son is five and my elder son is nine。我的小儿子5岁，大儿子9岁。 Tom is two years older than I.汤姆比我年长两岁。 2). elder在句中只用作定语，不作表语；older两者皆可。例如：My elder sister does her homework all by herself. 我的姐姐独自做作业。His elder son got married last week. 他的长子是上星期结婚的。I think his mother is ol
7、der. 我认为他的母亲年龄大引起。 3). elder只能用来指人；older不仅限于修饰人。例如：My elder brother joined the army when he was only fifteen.我哥哥年仅15负就参了军。This dog is older than any other dogs here.这条狗在这里是最老的一条。I have a sister older than myself.我有位比我大的姐姐。It is said Mr. Chen is over ten years older than Mrs. Li.据说陈先生比李女士大10多岁。题模精选题模
