四、总结（引深探究 15分钟）
形容词比较级的用法
1. 双方比较，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. 表示一方不如另一方时，用“less+原级+than”结构表示，意为“……不如……”。如：this room is less beautiful than that one .这个房间不如那个房间漂亮。
3. 表示一方超过另一方的程度或数量时，可在比较级前加表示程度的状语。如：even, a lot, a bit, a little , still, much, far , yet, by far等。如：the weather is even worse than yesterday.天气比昨天更糟糕了。
4. 表示一方随另一方的程度而变化时，用“th e +比较级（主语+谓语），the +比较级（主语+谓语）”结构，如：the harder he works, the happier he feels.他工作越努力，感到越快乐。
5. 不与其他事物相比，表示本身程度的改变时，用“比较级+and+比较级”的结构，意为“越来越……”。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. 在比较从句中，为避免重复，常用that(those),one(ones)代替前面出现的词。如：the book on the chair is more interesting than that on the desk.椅子上那本书比桌子上那本有趣。
7. 表示两者在某一方面相同时用“as+形容词或副词原形+as“的句型。如：i think english is as important as math.我认为英语和数学一样重要。
tom runs as fast as jack.汤姆跑地和杰克一样快。
8. 表示一方在某一方面不及另一方时用“not as /so+形容词或副词原形+as”的句型。如：it is not as/so warm today as y esterday.今天不如昨天暖和。
he did not come as /so early as wang lin.他不如王林来得早。
这种句型可以和第2种“less +原级+than “转换”。
it is less warm today than yesterday.
he came less early than wang lin.
