3、jumpalittlehigherthanhe. 我跳得比他高一点点。LondonisthebiggestcityinBritain. 伦敦是英国最大的城市。ShesingsthebestinClassTwo. 二班她唱歌最好。二、形容词和副词比较级、最高级的变化规则（1）规则变化的形容词及副词的比较级和最高级一般在词尾直接加er或est。例如：tall-taller-tallest，long-longer-longest以不发音的字母e结尾的单词在词尾直接加r或st。例如：nice-nicer-nicest以辅音字母+y结尾的词，把y变为i，再加er或est。例如：heavy-heavier

4、-heaviest重读闭音节，末尾只有一个辅音字母，双写这个辅音字母，再加er或est。例如：big-bigger-biggest部分双音节词和多音节词分别在原级前加more构成比较级和most构成最高级。例如：slowly-more slowly-most slowly；beautiful-more beautiful-most beautiful（2）不规则变化的形容词及副词的比较级和最高级原级比较级最高级good/wellbetterbestbad/ill/badlyworseworstmany/muchmoremostlittlelessleastfarfartherfarthestf

5、urtherfurthestoldolderoldesteldereldest三、比较级和最高级句型：（1）形容词及副词比较级的句型：1）比较级than.：比较为。即：“A 动词形容词或副词比较级thanB”。两者相比较，A比B更一些。例如：His brother is younger than I（me）. 他弟弟比我年轻。Beijing is more beautiful than Wuhan. 北京比武汉更漂亮。【注意】在比较级前有时可加一些修饰语，如much, a lot, a little, still, even等以示强调或加强语气。例如：This box is a little

6、heavier than yours.这个箱子比你的要稍重一些。This movie is much more interesting than that one.这部影片比那部有趣得多。2） as. as：和相同。 即：A+动词+as+形容词或副词原级+as+B，表示A和B两者比较，程度相同，“和相同”。例如：My uncle is as tall as your father. 我叔叔和你父亲一样高。My dog is as old as that one. 我的狗与那个狗年龄一样大。3） Anotas形容词或副词原级asB 表示A，B两者程度不同，即“A不如B那么”。例如：My uncl

7、e is not as tall as your father. 我叔叔不如你父亲高。Tom is not as honest as John. 汤姆不如约翰诚实。He cant run as /so fast as you. 他没你跑得快。4）“比较级+ and+比较级”或“more and more + 原级（多音节词和部分双音节词）”意为“越来越”。例如：Our city is more and more beautiful. 我们的城市越来越美丽了。More and more countries begin to save the financial crisis.越来越多的国家开始拯

8、救金融危机。5）“the + 比较级，the + 比较级”意为“越就越”。例如：The more you read, the more you know. 你书读得越多，你知道得就越多。（2）形容词及副词最高级的句型：1)one of the +最高级+名词复数，意为“之一”。例如：Lu Xun is one of the greatest writers last century.鲁迅是上世纪最伟大的作家之一。2)最高级+of (in/among)，意为“之中，最”。例如：Of all the movie stars, I think Zhang Ziyi is the best.在所有的电

9、影明星之中，我认为章子怡是最好的。3) This is / was + 最高级+名词+that定语从句，意为“这是最”。例如：This is the worst film that I have seen these years.这是我这些年来看过的最不好的一部电影。 四. 形容词和副词的比较级和最高级需要注意点：（1）当比较级后面有of the two之类的词语时，比较级前要加定冠词the。例如：Lucy is the taller of the twins.Lucy是双胞胎中比较高的那个。（2）如果后面接名词时，much more + 不可数名词，many more + 可数名词复数。例如

10、：The farmers have produced much more rice.这些农夫收了更多的稻谷。（3）old的比较级形式有older和elder。elder只用于兄弟姐妹的长幼关系。例如：My elder brother is a famous artist. 我哥哥是一名有名的艺术家。（4）far的比较级形式有farther和further。一般farther表示距离，而further表示更进一步。例如：I have nothing further to say.我没有什么要说的了。(5) 形容词最高级前必须加定冠词the，但如果最高级前有物主代词、指示代词、名词所有格等修饰时，

11、则不用定冠词。例如：My oldest daughter is 16 years old. 我最大的女儿16岁。(6) 形容词最高级常与由介词in或of引导的表示范围的短语连用。若介词后的名词或代词与句中的主语是同一事物时，则用of短语；当只说明是在某一空间、时间范围内的比较时，则用in短语。例如：This apple is the biggest of all. 在所有的苹果中，这个苹果最大。He is the youngest in his class. 他在他班里年龄最小。(7) 形容词最高级前可用序数词限定，共同修饰后面的名词，其结构为：the+序数词+形容词最高级+名词。例如：Hai

12、nan is the second largest island in China. 海南是中国的第二大岛。(8) 形容词最高级的意义还可以用比较级形式表达。常见的有：1)形容词比较级+than any other+单数名词。例如：This book is more difficult than any other book here.= This book is the most difficult book of all.这些书当中这本最难。2) 形容词比较级+than the other+复数名词。例如：Asia is bigger than the other continents o

13、n the earth.亚洲是地球上最大的洲。(9) 形容词最高级前若有不定冠词a，这时，它不表示比较，而表示“非常”的意思。例如：Spring is a best season. 春天是一个非常好的季节。例题讲解I.写出下列形容词与副词的比较级及最高级形式。 1. long _ _ 2. wide _ _3. fat _ _ 4. heavy_ _5. far _ _ 6. interesting _ _7. wet_ _ 8. hot _ _9. nice _ _10. much _ _II. 用所给词的正确形式填空。 1.
