[Comparatives/Superlatives]
（一）概念
比较级是将二者进行比较产生的词形，是由形容词或副词原级转化而来。相对二者的比较，还有三者及以上的比较，这时就产生了最高级。
Grammar
Focus
（二）adj./adv.变化规则
1.单音节形容词和部分双音节词（大多是以y、ly、er、ow、ble结尾的双音节形容词），一般在词尾加-er或-est。
e.g.
tall-taller-tallest
short-shorter-shortest
2.以一个元音加一个辅音结尾的词，且元音发短音时，双写尾字母，再加-er或-est。
e.g.
fat-fatter-fattest
Grammar
Focus
3.以“辅音字母+y”结尾的词，变“y”为“i”，再加-er或-est。
e.g.
happy-happier-happiest
4.多音节词（三音节及以上）和部分双音节词，在词前加more或most。
5.部分形容词和副词的比较级是不规则的。
e.g.
good/well-better-best
bad/badly-worse-worst
