fat-fatter

beautiful等。
二形容词和副词的比较级
1.比较级的范围：一般为两者或两个部分进行比较。例如：I’m taller than you.
2.比较级的结构：结构上比较级有三个明显的标志。
①than在比较级后：一般用than连接两个比较的部分。例如：Tom runs faster than Mike.其中Tom和Mike
是比较的两部分，用than连接他们进行比较。
（在than的句式中有一个需要同学们特别注意：I’m taller than any other students in my class.这句话中用than连接的是I
和any other students in my class两个部分，其实表示的是最高级的概念，译为我比我们班其他同学都要高，其中any other ……是固定搭配，译为任何其他的。）
②a little, much, a lot, even, still加在比较级前：可用来专门修饰比较级。例如：Lisa was sick yesterday,
while today she is much better.
③A as+形容词或副词原形+as B ：译为像……一样。例如：Mary is as clever as Susan.Mary像Susan
一样聪明。
另外，两个比较级连用表示“越来越”的意思。例如：Days get longer and longer in Spring.白天在春天越来越长了
三形容词和副词的最高级
1.最高级的范围: 最高级用于三者或三者以上的人或事物之间的比较，表示在众多人或事物中，其中一个"最……"。
例如：My ruler is the longest of all.我的尺是最长的。
a)最高级的结构：结构上比较级有两个明显的标志。
①the：一般用the限定最高级的范围，也可以说，现阶段the就是最高级的主要标志。但是，当形容词最高
级前有序数词、物主代词、指示代词、名词所有格等限定词修饰时，最高级前不加the。例如：He is our best teacher.他是我们最好的老师。
②最高级后面往往用of或in介词短语来表示形容词的最高级的比较范围。
of短语指的范围通常是一人或一些事物，而不是一个场所；如果指一个场所，则用介词in。例如：He is the strongest of the three.他是三个人中身体最强壮的。
He is the strongest in our class.他是我们班里身体最强壮
