lesson 6 形容词和副词(二)
内 容 提 要——形容词与副词比较级和最高级的基本用法
一、原级比较的基本用法
1. 原级比较由“as+形容词或副词(或再加名词或短语)+as ”构成“原级相同”比较句,表示两者比较;其否定式,即“程度不及”比较句型为“not so(as) +形容词或副词+as”,而且as…as结构前可用just, almost, nearly, quite等表示程度的词修饰
2. “as (so)+名词+as+名词”进行名词比较,这时一般情况下有一个表示原级的比较词,但如果第一名词前出现了形容词修饰该词或出现副词修饰谓语,应当用so而不用as
二、比较级
1. 比较级由“形容词(副词)比较级+than+…,”构成表示在两者中间一方比另一方“更加…”。连词than后可接句子,也可接名词、代词、名词短语、介词短语、动词、动词不定式、ING结构和ED结构,有时也可省去than.
2. 注意than前后两项相比较的人或事物要一致
三、最高级
1. 最高级用于三者以上比较,形容词的结构形式是“定冠词+形容词最高级+名词+表示范围的短语或从句”(如all, of all, of the tree, in the world, that has ever taken place等)
2. 副词的最高级与形容词最高级的区别在于最高级前没有定冠词the
四、同步练习
1) Walking briskly for thirty minutes will burn as many calories as .
[A] to run for fifteen minutes
[B] running for fifteen minutes
[C] you run for fifteen minutes
[D] fifteenminute walking
解析:B为正确答案。
2) The gorilla(大猩猩), while [A] not quite as curious than [B] the chimpanzee(黑猩猩), shows more persistence [C] and memory retention(记忆力) in solving [D] a problem.
解析:B错。改为 as ,和前面的as和形容词原形curious 一起构成同程度比较。
3) Alaska is twice [A] as larger [B] as [C] the next largest [D] state, Texas.
解析:B错。 改为as large.
4) Thomas Jefferson's achievements as an architect rival his contributions a politician.
[A] such [B] more [C] as [D] than
解析:C对。动词rival(胜过、匹敌)前后是两个相比较的成分achievements(成果)和 contributions(贡献),由于前面的名词后出现了短语 as an architect,故空白处也应用as,使前后对比成分一致。
5) I should say Henry is not much a writer as a reporter.
[A] that [B] so [C] this [D] as
解析:B为正确答案。
6) Natural mica(云母) of [A] a superior [B] quality is cheapest [C] to obtain than synthetic [D] mica.
解析:C错。应改为比较级cheaper.比较级后并不一定跟接连词than,有时在其间有名词或名词短语(被形容词所修饰),介词短语,不定式或其他成分隔开。
7) She is older than .
[A] any other girl in the group [B] any girl in the group
[C] all girls in the group [D] you and me as well as the group
解析:A为正确答案。“She”作为单个不能跟全组比(C和D不对),也不能跟全组所有相比,因为“她”也是其中一员,自然“她”不能跟自己相比。这里“She”比较的是“这组中的任何一个”,所以A对。
8) Josephine McCrackin joined [A] the “Santa Cruz Sentinel” in 1905 and, until her death fifteen years late [B] , remained [C] active in journalistic [D] work.
解析:B错。应改为比较级later,因此处实为与1905年相比晚15年,故应使用比较级。
9) The purpose of the research had a more important meaning for them than .
[A] ours [B] with us [C] for ours it had [D] it did for us
解析:D为正确答案。
10) Sound travels air.

[C] through water faster and[D] where it is faster through water than through
