目标导引(相信自己你能行)。让学生说出描述自己比别人更棒的三个以上的形容词。明白新课内容。
老师导入:大多数的形容词和副词都有三个级别。原级,比较级,最高级。其中比较级表示”更…”。用于两者之间的比较。用来说明前者比后者更…。比较级前面一般用much,Even。a little修饰。其中even, much只能修饰比较级。当三个或三个以上的人或事物进行比较时,需要用到形容词,副词的最高级。表示”…是最…的”。用the加形容词,副词的最高级的结构,后面可以加上表示范围的介词短语或从句。

难点突破:
形容词和副词有三个等级:
原级
比较级
最高级
① 程度副词very, too, so, quite等修饰形容词的原级
如:very tall、 too hot、 so cold
The car is quite/very cute.
The flood is very/so serious.
as+adj.+as 和...一样
as funny as as big as
as happy as as smart as
这个故事和那个故事一样有趣。
The story is as interesting as that one.
否定形式: not so/ as+adj.+as 和… 不一样
这个问题不如那个问题难。
The question is not as difficult as that one.
比较级+than…
This cake is more delicious than that one
(两者之间比较)
数字+倍数 + 比较级+than ....
This garden is 9 times larger than that one.
the +比较级, the +比较级
越……, 越……。
the +比较级+of the two…
Amy is the shorter of the two.
Davie is the taller of the two.

规则变化的形容词及副词的比较级和最高级。分为五种情况。
A,一般在词尾加er或est。
B.必以不发音的字母e结尾的单词在词尾直接加r或st。
C. 以辅音字母加y结尾的词,把y变为i,再加er或est。
D. 以重读闭音节结尾末尾只有一个辅音字母的双写这个辅音字母再加er或est。
E. 部分双音节词和多音节词分别在原级前加more构成比较级和most构成最高级。
二,不规则变化的形容词及副词的比较级和最高级。主要是good well。等等一些词刚才已经在课堂上重点讲过了,大家一起回忆一遍。(大声说出来)
三,比较级和最高级的句型。请大家再次看自己的笔记或课件进行复习。(互相提问笔记内容)
