This story is more interesting than that one. 2） A=B（as+原级+as） This cake is as big as that one. Swimming is as exciting as climbing.3） A B ( not as/so+原级+as 与不一样,more+原级 超过) Jim is not as/so tall as Li Lei. John is more hard-working than Joan. English is more useful than Japanese. = Japanese is not so/as useful as English.二、形容词，副词的比较级中，asas，soas的用法 as + 形容词或副词原级 + as1）在否定句或疑问句中可用so as。 He cannot run so/as fast as you.2）当as as 中间有名词时采用以下格式。 as +形容词+ a +单数名词 as + many/much +名词 This is as good an example as the other is. I can carry as much paper as you can.3）用表示倍数的词或其他程度副词做修饰语时，放在as的前面。 This room is twice as big as that one. Your room is the same size as mine.4) 倍数+ as + 形容词 + as= 倍数+ the+名词 + of+其它 This bridge is three times as long as that one. This bridge is three times the length of that one. Your room is twice as large as mine. Your room is twice the size of mine.三、 使用比较级需注意的事项1）要避免重复使用比较级。 (错) He is more cleverer than his brother. (对) He is more clever than his brother. (对) He is clever than his brother.2）要避免将主语含在比较对象中。 (错) China is larger that any country in Asia. (对) China is larger than any other countries in Asia.3）要注意对应句型，遵循前后一致的原则。 The population of Shanghai is larger than that of Beijing. It is easier to make a plan than to carry it out.4）要注意冠词的使用，后有名词的时候，前面才有可能有冠词。比较：Which is larger, Canada or Australia? Which is the larger country, Canada or Australia? She is taller than her two sisters. She is the taller of the two sisters.可修饰比较级的词1）a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even2）还可以用表示倍数的词或度量名词作修饰语。3）以上词(除by far)外，必须置于比较级形容词或副词的前面。典型例题:1）- Are you feeling _? - Yes，Im fine now.A. any wellB. any betterC. quite good D. quite better答案：B. any 可修饰比较级，quite修饰原级，well的比较级为better.2）The experiment was_ easier than we had expected.
