比较级语法讲练一、概念比较级就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。
二、adj./adv.变化规则（一）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。
e.g. tall—taller short—shorter small—smaller（二）以字母e结尾的词，在词尾直接加-r。
e.g. nice—nicer（三）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。
e.g. fat—fatter（四）以"辅音字母+y“结尾的词，变”y“为”i“，再加-er。
e.g. early—earlier（五）多音节词（三音节及以上）和部分双音节词，在词前加”more“。
（六）部分形容词和副词的比较级是不规则的e.g. good/well-better bad/badly-worse。
