形容词和副词用法比较
形容词和副词形容词和副词在语法结构中主要用于比较级和最高级。形容词和副词的构成形式基本上一样，它们的形式与单音节、双音节和多音节有关，当然还有其特殊形式。形容词和副词比较级的基本用法分为同级比较、比较级和最高级三种形式。但这三种形式都有它们特殊的表达方式以及它们的惯用法。对以下要点大家须一一掌握。
第一节 形容词比较级和最高级的形式
一、形容词比较级和最高级的构成
形容词的比较级和最高级变化形式规则如下
构 成 法 原 级 比 较 级 最 高 级
① 一般单音节词末尾加 undefinedundefinedundefined和 undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined②
单音节词如果以 undefined结尾，只加 undefinedundefined和 undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined③ 闭音节单音节词如末尾只有 一个辅音字母，
须先双写这个辅音字母，再加 undefinedundefined和 undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined④ 少数以 undefinedundefined undefinedundefinedundefined或 undefinedundefinedundefinedundefinedundefined undefinedundefinedundefined undefinedundefinedundefined结尾的双音节词，
末尾加 undefinedundefined和 est(以 undefined结尾的词，如 undefined前是辅音字母，
把y变成i，再加 undefinedundefined和 undefinedundefinedundefined，以 undefined结尾的词仍
只加 undefined和 undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined⑤ 其他双音节和多音节词都在前面加单词more和most different more
different most
different
1) The most high 〔A〕 mountain in 〔B〕 the world is Mount Everest， which is situated 〔C〕 in Nepal and is
twenty undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined〔D〕 .
2) This hou is spaciour 〔A〕 than that 〔B〕 white 〔C〕 one I bought in Rapid City， South Dakota 〔D〕 last year.
3) Rearch in the social 〔A〕 sciences often proves difficulter 〔B〕 than similar 〔C〕 work in the physical 〔D〕 sciences.
二、形容词比较级或最高级的特殊形式：
1. 三个或三个以上音节的形容词只能加more和most
只能说 more beautiful而不能说beautifuller; 只能说the most beautiful而不能说beautifullest。
但是，以形容前缀 undefinedundefined结尾的三音节形容词不适合上述情况，如unhappy,
untidy，我们可以说：unhappier→unhappiest, untidier→untidiest
2. 由 undefinedundefinedundefined分词和 undefinedundefined分词演变过来的形容词(包括不规则动词如know→known)只能加more或most来表示它们的比较级和最高级
more(most) striking, more(most) interesting, more(most) wounded, more(most)worn等。
4) The drawings 〔A〕 of the old masters 〔B〕 are among the treasuredest 〔C〕 works in muums 〔D〕 .
3. 英语里有些形容词由于其词义而不可能有比较级形式
absolute fatal main right universal
chief final naked simulta- utter
entire foremost perfect neous vital
eternal undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedficient undefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined
三、不规则形容词的比较级和最高级形式
good
well undefinedundefinedundefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedundefinedundefined
bad
ill undefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedundefinedundefinedundefined
many
much undefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedundefinedundefined
little
few undefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedundefinedundefinedundefined
far undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedundefinedundefinedundefinedundefined undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined
5) African elephants are larger， fiercer， and difficulter 〔A〕 to tame 〔B〕 than 〔C〕 Asian elephants 〔D〕 .
6) Sarah Hale became 〔A〕 one of the famoust 〔B〕 magazine 〔C〕 editors in the United States during 〔D〕 the 1800’s.
7) Of all 〔A〕 the Native American tribes 〔B〕 ， the Shawnee Indians were 〔C〕 a most 〔D〕 transient.
四、例题解析
1) A错。应将“most high”改为highest。这是在考形容词比较级的构成形式。
2) A错。改为more spacious。
3) B错。 改为more difficult。
4) C错。 treasured 在本句中是 undefinedundefined分词(动词treasure ＋ed)作形容词使用，是“宝贵的、珍贵的”意思，修饰名词 works(作品)，其最高级形式应用 the most treasured。
5) A错，改为more difficult。
6) B错。改为“the most famous”，因为famous(著名的)是双音节，其最高级变化应在前面加“the most”。
7) D错。应改为“the most”，因为此处表示的是最高级，“the most transient”意为“(延续时间)最短暂的”。
第二节 副词比较级和最高级的形式
副词比较级和最高级的变化形式与形容词基本上一样
一般 副词
hard→harder →hardest
fast→faster →fastest
late→later →latest
early→earlier →earliest
特殊 副词
well →better →best
much →more →most
badly →wor →worst
little →less →least 但是，开放类副词即以后缀 undefinedundefined结尾的副词不能像形容词那样加 undefinedundefined或 undefinedundefinedundefined，如
quickly →more quickly →most quickly quietly →more quietly →most quietly
〔注〕： early中的 undefinedundefined不是后缀，故可以把 undefined变 undefined再加 undefinedundefined和 undefinedundefinedundefinedundefined
第三节 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
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〕 fifteen undefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefinedundefined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.
3) Alaska is twice 〔A〕 as larger 〔B〕 as 〔C〕 the next largest 〔D〕 state， Texas.
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
4) Thomas Jefferson’s achievements as an architect rival his contributions a politician.
〔A〕 such
〔B〕 more
〔C〕 as
〔D〕 than
5) I should say Henry is not much a writer as a reporter. (88年考题)
〔A〕 that
〔B〕 so
〔C〕 this
〔D〕 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、 undefinedundefinedundefined结构和 undefinedundefined结构，有时也可省去than。
6) Natural mica(云母) of 〔A〕 a superior 〔B〕 quality is cheapest 〔C〕 to obtain than synthetic 〔D〕 mica.
7) She is older than .
〔A〕 any other girl in the group
〔B〕 any girl in the group

8) Jophine McCrackin joined 〔A〕 the “Santa Cruz Sentinel” in 1905 and， until her death fifteen years late 〔B〕 ， remained 〔C〕 active in journalistic 〔D〕 work.
2. 注意than前后两项相比较的人或事物要一致
9) The purpo of the rearch had a more important meaning for them than .
〔A〕 ours
〔B〕 with us
〔C〕 for ours it had
〔D〕 it did for us
