Unit 3 L1 导学案

1.I know ：我知道形容词比较级怎样构成：

1)规则变化

2)不规则形容词的比较级：(参考课本P 114填写下表)

最高级

2.比较级的用法：

(1) 方比较，表示一方超过另一方时，用“比较级+than ”结构表示， 意为 “比……”。

如：This bike is better than that one.这辆自行车比那辆好。

(2)三者或三者以上比较用，前加the，后有of / in表范围,

意为“最…”.（同类of, 不同类in.）。(注：副词的最高级前the可省。)

in his class.

He is the tallest

of three.

Zhang Hua is the tallest of all the students.

Tom jumps (the) farthest of all the students.

(3)两者比较，表示不如另一方时，用“less+原级+than”

如：This room is less beautiful than that one .这个房间不如那个房间漂亮。☆注：“not as /so+形容词或副词原形+as”也表示“不如”，

可与“less+原级+than”结构互换。

如：今天不如昨天暖和。有一下两种说法：

It is not as/so warm today as yesterday

It is less warm today than yesterday.

(4)越…越…，用“the +比较级（主语+谓语），the +比较级（主语+谓语）”。如：The harder he works, the happier he feels.他工作越努力，感到越快乐。

(5)越来越…“比较级+and+比较级”。

如：The weather is getting hotter and hotter.天气越来越热了。

The girl becomes more and more beautiful.这个女孩变得越来越漂亮了。(6)表示两者相同时用“as+形容词或副词原形+as”。

如：I think English is as important as math.我认为英语和数学一样重要。

试一试：挑错改错

①He is thiner than his brother. 将改为

②The story is interestinger than that one. 将改为

③He is the tallest in all. 将改为
