4、节词末尾加er 和 est strong stronger strongest 单音节词如果以e结尾，只加r 和st strange stranger strangest 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er和est sad big hot sadder bigger hotter saddest biggest hottest 少数以y,er(或ure),ow,ble结尾的双音节词， 末尾加er和est(以y结尾的词，如y前是辅音字母， 把y变成i，再加er和est，以e结尾的词仍 只加r和st) angry clever narrow noble ang

7、st beautiful而不能说beautifullest。 但是，以形容前缀un结尾的三音节形容词不适合上述情况，如unhappy,untidy，我们可以说：unhappierunhappiest, untidieruntidiest 2. 由ING分词和ED分词演变过来的形容词(包括不规则动词如knowknown)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 mas

11、red。 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 hardharder hardest fastfaster fastest latelater latest earlyearlier earliest 特殊 副词 well b
12、etter best much more most badly worse worst little less least 但是，开放类副词即以后缀ly结尾的副词不能像形容词那样加er或est，如 quickly more quickly most quickly quietly more quietly most quietly 注： early中的ly不是后缀，故可以把y变i再加er和est 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
13、型为“not so(as) 形容词或副词as”，而且asas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 .

15、n 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、ING结构和ED结构，有时也可省去than。 6) Natural mica(云母) o

21、hievements(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) B为正确答案。 6) 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) 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) B错。应改为比较级later，因此处实为与1905年相
22、比晚15年，故应使用比较级。 9) D为正确答案。 10) A为正确答案。 11) D错。 改为his masters。 12) A错。 改为most。 13) C错。改为the， significant是多音节形容词，在此处应用最高级形式(在前面加 the most)，注意句中的“of all ”。 14) C为正确答案。本句空白处缺状语，A和B全为名词短语，不符合条件；D为句子，和空白后面的句子没有任何联系，故亦应排除。只有C正确，和后面的最高级the most familiar前后呼应。 第四节 形容词和副词的特殊表达法 一、形容词与副词的同级比较： 由“as(so)as”引出，其否定式
23、为“not so”或“not asas”,考生还应注意下列含有“as”结构或短语的句子 1. as such：表示上文所指明的事或人 He is a child,and must be treated as such. 他是个孩子，必须被当作孩子对待。 2. as much：表示“与同量” Take as much as you like. 拿多少都行。 I would gladly have paid twice as much for it. 就是价格再贵一倍，我也会愿意把它买下的。 He as much as admitted the whole story. 他几乎全部承认了。 3.
24、as many：表示“与一样多” I found six mistakes in as many lines. 我在六行中发现了六个错。 二、表示“几倍于”的比较级：用twice (两倍)，four times (四倍)，ten times (十倍)加上as as 结构 This one is four times as big as that one. 这个是那个的四倍大。(这个比那个大三倍。) / Our campus is three times as large as yours. 我们的校园比你们的大两倍。 / He has books twice as many as she do

29、te 与lately late意思是晚； lately 意思是最近 You have come too late. What have you been doing lately? 3) deep与deeply deep意思是深，表示空间深度；deeply时常表示感情上的深度，深深地 He pushed the stick deep into the mud.

31、何排列? 为什么不能说a black new pen，而要说成a new black pen? 这里面有无规则可循?如果你记住Opshacom这个为帮助记忆而杜撰的词，就能掌握英语中形容词排列的顺序。Opshacom中op代表opinion，指表示人们观点的形容词，如beautiful，horrible，lovely，nice等；sh代表shape，指表示形状的形容词，如long，short，round, narrow等；a代表age，指表示年龄、时代的形容词，如old，new， young等；c代表colour，指表示颜色的形容词，如red,black, orange等；o代表origin，指表示国籍、地区的形容词，如British，Canadian，German等；m代表material，指表示材料的形容词，如plastic，metal，aluminium等。英语中这六类形容词连用时就按上述先后顺序排列，如a nice long new black British plastic pen当然，实际语言使用中不可能出现这么多形容词连用的情况。-第 11 页-
