小学生英语比较级及练习.doc

比较级得变化规则
1.一般在原级后加er 构成比较级，加est构成最高级。
e.g. small       smaller         smallest
    young       younger        youngest
2.以不发音的字母e 结尾的形容词，直接加r 或st 构成比较级和最高级。
e.g. nice        nicer            nicest
     late        later            latest
3.以辅音字母+y 结尾的形容词，变y为i ，再加er 或est, 构成比较级和最高级。
e.g. busy          busier            busiest
    heavy          heavier          heaviest
4.在重读闭音节中，末尾只有一个辅音字母的形容词，要先双写这个辅音字母，再加er或est， 构成比较级和最高级。
e.g. hot           hotter            hottest
     big           bigger            biggest
5.个别形容词的比较级和最高级是不规则变化，需个别记忆。
e.g. good (well)      better      best
　　bad (badly, ill)  worse      worst
　　many(much)      　more       most
　　little            less        least
　　far              father      farthest
