Play as well as you can. 否 定 形 式 not + so (as) +原级+as (不如……那样) English is not so difficult as science. She does not study so well as I do. 比较级 不同程度 （用于两者比较） 比较级+than (比……) Jim is older than Lucky. I like pork better than beef. 比较级前面可以加 much, far, even,still, a lot, a little, a bit等 有of the two或of the twins时 the+比较级 （两者之中较...） Of the two women, she is the taller one. Lucy is the thinner of the twins. 程度加深 比较级+and+比较级 （越来越……） The + 比较级，the + 比较级 （越……, 越……） He is growing taller and taller. He studies better and better. The more books she reads, the better she understand. 最高级 最高程度 （用于三者或三者以上） The +最高级+of (in) (最……) Spring is the best season of the year. Lin Tao jumped (the) farthest of all. 副词最高级前面的the 往往省略 形容词最高级前的the不能省略 与比较级最高级有关的知识点 ◇further指“程度更深” 记住以下三个词组：further study(进修) further education(继续教育) further information (进一步的信息) ◇elder仅用于同辈之间的排行，如: elder sister(姐姐)，elder brother (哥哥) ◇less作为“更少”仅用来修饰不可数名词，修饰可数名词表示“更少”要用fewer。 ◇句型一：比较级+than + any (other) +名词单数形式 Shanghai is larger than any other city in China. （上海在中国这个范围内，所以用any other） Shanghai is larger than any city in Jiangsu.（上海不在江苏范围内，所以只需用any） ◇句型二：比较级+than + the other +名词复数形式 Daniel is more hard-working than any other student in our class. =Daniel is more hard-working than the other students in our class. ◇序数词通常只修饰最高级。 Africa is the second largest continent. The Yellow River is the second longest river in China. This is the third most popular song of Michael Jackson. ◇为避免重复，我们通常用that, those, one, ones代替前面出现的名词。that代替可数名词单数和不可数名词，those代替可数名词复数。one既可指人又可指物，只能代替可数名词。 The weather in China is different from that in America. The book on the table is more interesting than that(或the one)on the desk. A box made of steel is stronger than one made of wood. ◇“否定词 + 比较级”相当于最高级。 --Wait until we get a satisfactory reply, will you --I couldn’t agree more(我再同意不过了/我非常同意). The idea sounds great to me. Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing. ◇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 don’t 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. ◇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. She tells more funny jokes than we do. ... ...
