形容词和副词的比较级.docx
8页形容词和副词的比较级重难点:比较级的构成和用法□ 比较级的定义:英语中只有形容词和副词才有比较级,其他词没有比较级大多数 形容词和副词都有三个级别,即:原级(原形)、比较级、最高级其中比较级表示 “更...”,用于两者之间的比较,用来说明“前者比后者更...”,比较级前一般用much, even, a little修饰,其中even, much只能修饰比较级□ 英语中的音节:一般地说,英语中有几个发音的元音字母就有几个音节一个单词 里,若有出现了一个元音音标,就是单音节,如:calm, tall, smart;若单词里出现 了两个元音音标,即2个发音的元音字母,则是双音节,如:careful, useful;若单词 里出现3个或3个以上发英的元音,则是多音节总之,到音标中去找发音的元音 字母,有几个元音字母发音,就是几个音节□ 重读闭音节词:辅音+元音+辅音(中间的元音字母发单元音)如:big, thin, hot二:形容词和副词的比较级的构成:1. 形容词的变化规则(1) (规则变化)单音节词和少数双音节词① 一般在词尾加上-er.例如:calm-calmer, tall-taller, great-greater② 以不发音e结尾的单词直接在词尾加-r例如:nice-nicer fine-finer large-larger brave-braver③ 双音节中,以“辅音+y结尾的单词,要变y为I,再加-er.例如:happy-happier busy-busier early-earlier④ 以重读闭音节结尾且末尾只有一个辅音字母,应先双写这个辅音字母,再加-er.例如:big-bigger thin-thinner hot-hotter多音节和部分双音节⑤ 多音节或部分双音节的形容词在原级前面加more。
例如:popular-more popular important-more important Serious-more serious careful-more careful(2) 不规则变化:少数形容词的比较级变化是不规则的原级比较级good/wellbetterBad/illworseMany/muchmorelittlelessfarfarther/fUrtheroldolder/elder2. 副词的变化规则(1)(规则变化)① 单音节词后缀-er例如:high-higher hard-harder early-earlier② 双音节词,在其前面加more例如:bravely-more bravely carefully-more carefully(2)不规则变化原形比较级Wellbetterbadlyworselittlelessmuchmorefarfarther/further二:形容词和副词原级的用法① Very, so, quite, too等词后面用原级② too...to; so that...; as as 中间用原级③ A+ be+ not as/so +原级+as B: 表示 A 不如 B.④ 表达“A和一样”,即A=B (程度相同),用as.as结构例如: He is as tall as Tom./He runs as fast as Tom.⑤ AB(表示A超过B),用比较级+than.结构例如:He is taller than me.注意:① 只有形容词和副词才能用此结构,且只有同类事物才能比较。
例如 1: Her bag is bigger than mine.不能说 Her bag is bigger than I.例如 2: The weather of Chongqing is much better than that of Beijing.不能说:The weather of Chongqing is much better than Beijing.② 在比较级的主句+than从句中,从句常常省去和主句相同的部分(常用代词来 this/these, that/those, one/ones 代替),而只剩下对比成分例如: This picture is more beautiful than that one.Your room is much larger than mine③ 按语法规则,than后面的人称代词应当用主格,但口语中有时用宾格代替例如:He is more careful than I (me).④ 比较级前面可以加上表示优劣程度的词或短语,意思是“更...”,“….得…”常见的 有 much, a little, a bit, a lot, a great deal, even, still, far 等例如:He is much taller than I.他比我要高得多。
I jump a little higher than he.我挑得比他高一点点⑤ 避免与自身相比如:[误]Shanghai is bigger than all the cities in China.[正]Shanghai is bigger than all the cities in China.例:Shanghai is bigger than in Jiangsu.A. any other cities B. all the other cities C. any cities D. other cities2.形容词和副词比较级的更多用法1) 比较级+and +比较级,表示“越来越...”Eg: In spring the days get longer and longer.Eg: Our city is becoming more and more beautiful.(2) the+比较级,the+比较级:表示越......就越.......Eg: The more, the better.Eg: The busier he is, the happier he feels.Eg: The more you eat, the fatter you will become.(3) “ The+比较级+of the two” : “两个中比较 的”,“两者之间最 ”例如:This watch is the cheaper of the two.这只手表是两个中比较便宜的。
He is better of the two .他是两个人中比较好的Of the two boys, John is cleverer.(4) Which(who)is + 比较级 ?“比较A和B,问哪一个较....? ”时,用”which is +比较级,A or B?"句型表示如果是 人与人相比时,用who代替which.例如-Which one is more popular, the radio or the movie?- The radio is.注意:A or B,只能用or,不能用and.-Who is happier, you or your father?-I am. / My father is.(5) 比较级还可以用年龄、数量、倍数等词组修饰表示具体“大多少”,“小多少”,“长 多少”,“短多少”等公式:数量词+比较级Eg: The mountain is 3 times higher than that one.Eg: Our room is 4 times larger than theirs.My sister is two years older than me.(6) 比较级+than any other+单数名词:比其他任何 都(注意同义句转换)例如: He is better than any other student in his class=He is better than any other students in the class.=He is the beat student in the class.注意:比较级+血〃 any other +n.(单)(适用于范围一致时)(all) other +n.(复)any +n.(单)(适用于范围不一致时)He is taller than "any other student / all other students in his class.I any student in my class.(三)最高级当三个或三个以上的人或事物进行比较时,我们需要用到形容词(副词)的最高级。
1. 表达“…是...中最...的”,用“the+形容词(副词)的最高级”的结构后面可以加上表示范 围的介词短语或从句公式:主语+be动词+the +形容词最高级+ (名词)+表示范围的介词短语或从句主语+实义动词+ (the) +形容词最高级+表示范围的介词短语或从句Eg He is the tallest (student) in our class.He jumps the highest of the three boys.This is the best book that I have ever read.2. 表示“最...的...中一个”,用“one of +the +最高级+复数名词”的结构来表达Eg He is one of the best students in our class.他 是我们班最好的学生之一This is one of the most beautiful flowers in the garden这是花园里最漂亮的花之注意:1) 形容词的最高级前面有定冠词the ,而副词的最高级前面定冠词the可以省略但在形 容词最高级前有物主代词时,不能要定冠词the.2) 常见的用来表示范围的介词有in, of, among比较级和最高级注意的点:① His bike is newer than hers.(见到 than 必须用比较级)② Jim is the tallest in our class.(在班集等集体内用介词in来表示比较的范围)③ Jim is the tallest of all (the students).(见到 of all 要用最高级)=Of all the students, Jim is the tallest.④ Jim is the tallest of the three.(见到 of the three 要用最高级)⑤ Which is bigger, a tiger or a monkey ?(两者比用比较级)⑥ Which is the biggest, a tiger, a dog or a monkey ?(三者或三。
