规则变化
单音节词（只读一个元音，两个辅音间有多个元音也读成一个元音）和少数双音节词，加词尾-er，-est来构成比较级和最高级。
1.一般单音节词未尾加-er,-est。great(巨大的) greater greates t tall(高的) tallertallest
2.以不发音的e结尾的单音词和少数以- le结尾的双音节词只加-r,-st。nice(好的) nicer nicestlarge(大的) larger largest able（有能力的) abler ablest
3.以一个辅音字母结尾的闭音节单音节词，双写结尾的辅音字母，再加-er，-est。big(大的) bigger biggest hot热的) hotter hottest
4."以辅音字母+y"结尾的双音节词，改y为i，再加-er，-est。easy(容易的) easier easiest busy(忙的) busierbusiest
5.少数以-er，-ow结尾的双音节词未尾加-er，-est。clever(聪明的) clevere r clevere st narrow(窄的) narrowe r narrowe st
6.其他双音节词和多音节词，在前面加mor e，most来构成比较级、最高级。importa nt(重要的) more importa nt most importa nt easily(容易地) more easily most easilyyou can let go
比较级的句子结构通常是：
什么+ 动词be (am , is , are ) + 形容词比较级+ than（比）+ 什么,
如：I‟mtallerand heavier than you. （我比你更高和更重。）
An elephan t is biggerthan a tiger. （一只大象比一只老虎更大。）
☆注意比较的两者应该是互相对应的可比较的东西。
典型错误：My hair is longerthan you.（我的头发比你更长。）
比较的两者是我的头发、你（整个人），那么比较的对象就没有可比性。
应该改为：My hair is longerthan yours. 或My hair is longerthan your hair.

动词的过去式形式
1.规则动词的过去式词尾变化有几种:
ⅰ.一般情况下+ed, 如: watched, planted, watered, climbed等.
ⅱ.以不发音的字母e结尾的+d. 如: liked, tasted等.
ⅲ.以辅音字母+y结尾的变y为i 再+ed. 如: study→studied
2.规则动词的词尾读音
ⅰ.在浊辅音和元音后读/d/，如:lived, listene d等.
ⅱ.在清辅音后读/t/如: liked, helped, watched等.
ⅲ.在/t/, /d/音后读/id/ 如:planted.
3.不规则动词的过去式变化则没有什么规律，请大家在平时学习的过程中背熟记牢.
构思的意思表示一般过去式的动词通常用动词的过去式形式来表示，而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。规则动词的过去式变化如下：
（1）一般情况下，动词词尾加-ed ，如：
workedplayedwantedacted
仍然的意思
（2）以不发音的-e 结尾动词，动词词尾加-d，如：
lived moved decided decline d hoped judgedraidwiped
（3）以辅音字母+ y结尾的动词，把-y变为-i 再加-ed，如：
studied tried copiedjustifi ed cried carried embodie d emptied
（4）以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加-ed，如：
stopped beggedfretted dragged dropped planned dotteddripped
（5）注：不规则动词的过去式变化规律性不强，须多加记忆。
go - went，make - made，get - got ，buy - bought，come - came ，fly-flew ，is/am-was，are-were ，e-saw ，bring-brought，do-did，teach-taught, think-thought, are-were, say-said,sit-sat. read-read, spend-spent.（部分）
