同学们，想一想good和well，bad和badly的比较级和最高级如何写？
同学们，想一想，carefully的比较级和最高级如何写？
Let’s
learn.
Good-better-best
Well-better-best
Bad-worse-worst
Badly-worse-worst
Carefully-more
carefully-most
carefully
那发现了什么规律呢？
Let’s
learn.
形容词比较级和最高级的构成：
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或者-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或者-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
many(much)-more-most
bad
(badly,
ill)-worse-worst
little-less-least
Far-father-farthest或further-furthest
Let’s
learn.
副词的比较级和最高级:
1.以-ly结尾的副词，除early
变为earlier
和earliest外，其余一律在其前加more和most如:
carefully-
-
more
carefully-
-most
carefully
2.规则变化直接加-er和-est。如:
fast-
-faster-
-fastest
3.个别词是不规则变化，需要特别记忆。
如:
well
一better
-
best
far
-
farther
-
fastest
badly
-
worse
-
worst
4.句子中，副词最高级前的the可省略也可以不省略，但形容词最高级前面的the绝对不能去掉。
