The idea sounds great to me.我完全同意你。这个主意听起来对我来说很重要。Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing.没有什么事情比这个更难了。（这个是最难的） 比较级前一般不加冠词。但表示两者中较突出者，且比较级后又有名词或出现了of the two，这时比较级前一定要加the。He is the taller of the two.他是两个人之中高的一个。Of the two jobs，he chose the harder.在这两个工作中，他选择难一些的。Which is the younger one, Lily or Lucy?哪一个更年轻，莉莉还是露西？试比较：Which is larger, Canada or Australia?加拿大，澳大利大哪一个（领土面积）大？Which is the larger country, Canada or Australia?加拿大，澳大利亚，哪一个（领土面积）大？She is taller than her two sisters.她比她两个妹妹要高。She is the taller of the two sisters.她是他们两个姐妹中高的一个。不含than 的比较级前可加不定冠词修饰，构成“a/an+比较级+单数可数名词”表示“一个更的人/物”。Why dont you use a sharper knife? 你为什么不用一把更锋利的刀呢？比较级than 后应用人称代词的主格，但非正式语体中常用宾格。He is taller than I/me.他比我高。为避免重复，比较级中同样的动词用助动词do, does, did替代。I spend less time doing homework than John does.我比约翰花费在做作业上的时间少。She tells more funny jokes than we do.她讲的有趣笑话比我们（讲的）多。形容词most前面没有the，不表示最高级的含义，只表示“非常”。It is a most important problem.=It is a very important problem.他是很重要的问题。倍数表达法 A is three(four, etc.)times the size(height, length etc.)of B.The new building is four times the size(the height)of the old one.这座新楼是那座旧楼的四倍大（高）/这座新楼比那座旧楼大（高）三倍。A is three(four, etc.)times as big(high, long, etc.)as B.Asia is four times as large as Europe. 亚洲是欧洲的四倍大/亚洲比欧洲大三倍。A is three (four, etc.)times bigger(higher, longer, etc.)than B.Your school is three times bigger than ours.你们的学校比我们的学校大三倍。用times表倍数通常用于三倍以上，两倍可以用twice或double.形容词副词比较级最高级重点句型归纳句型一：形容词或副词比较级+than注意事项：该句型为比较级的最基本句型。只要看到than，即可确定前面使用比较级。He is taller than I am.他比我高。The boy does his homework more carefully than the girl.这个男孩做作业比这个男孩认真。句型二：less + 形容词的原级 + than注意事项：该句型表示“不如、不及”，特别需要注意的是，less本身就是little的比较级，后面必须跟形容词的原级，否定就造成了比较级的重复使用。This computer is less expensive than that one.这台电脑比那台便宜。句型三：as +形容词或副词的原级+ as注意事项：该句型表示对比的两者程度相当，as之间必须跟形容词或副词的原级，决不能使用比较级。此外，还要确定使用形容词还是副词。确定的依据就是根据第一个as前的动词，如果是系动词（如be，感官动词look, sound, smell, taste, feel等），那么就用形容词的原级，如果前面的动词是一般的实义动词，那么就必须用副词的原级修饰动词。This lesson is as easy as that one.这节课和那节课一样容易。Lucy talks with old people as politely as her sister.露西和老人交谈和与他妹妹交谈一样礼貌。特别提醒：asas之间也可以跟名词，句型如下： as +形容词+ a/an +单数名词+as He is as kind a person as his father. 他和他爸爸一样都是善良的人。 as + many/much+不可数名词/可数名词复数+as I can carry as much paper as you can. 你能搬多少纸，我也能。 I have as many books as you do. 我的书和你的一样多。 Well give you as much help as we can. 我们将尽我们所能给你帮助。 其它几个关于asas的句型： as as one can：尽其所能 He began to
