　　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.
