一.形容词和副词 知识要点 1)英语中大多数形容词、副词是可以分等级的,一般有三个等级:原级,比较级和最高级。形容词、副词的本来形式就是形容词的原级。如:John is a tall boy.两者间进行比较用到形容词比较级。如:Jim is taller than John.三者或者三者以上进行比较用形容词的最高级。Mike is the tallest of the three boys.(形容词最高级前面要加定冠词the) 2).形容词、副词比较级和最高级有规则变化和不规则变化 规则变化 ①单音节或双音节的形容词(或副词)比较级+er最高级+est small-smaller-smallest等 ②以e结尾的词,比较级+r,最高级+st即可nice-nicer-nicest ③以辅音字母+y结尾的,变y为i+er或est easy-easier-easiest ④双写最后一个辅音字母+er或est hot-hotter-hottest ⑥ 一些双音节及多音节形容词或副词前要加more和most,如: difficult---more difficult---most difficult 不规则变化: good/well-better-best, bad-worse-worst many/much-more-most little-less-least far-further -furthest(表示程度) far-farther-farthest(表示远近) old-older-oldest(表新旧) old-elder-eldest(表兄弟姊妹之间的长幼) 3).比较级前的修饰词:a little, a lot, much, even; far; still 4)形容词、副词比较级的特殊用法 ①形容词/副词比较级+than+ any other+单数名词(+介词短语)"表示"比同一范围的任何一个人/物都……",含义是"最……"。 例如,Mike gets to school earlier than any other student in his class. = Mike gets to school earlier than any of the other students in his class. = Mike gets to school earlier than the other students in his class. = Mike gets to school earliest in his class.注意:Mike gets to school earlier than any student in Tom's class. ②"the+形容词比较级+of the two+……"表示"...是两者中较…的"。 如,Look at the two boys. My brother is the taller of the two. ③"比较级+and+比较级"表示"越来越……"。He is getting taller and taller. ④"the+比较级,the+比较级"表示"越…,越…,"。The more careful you are,the fewer mistakes you'll make 5).最高级常用句型结构 ①"主语+be+ the+形容词最高级+单数名词+in/of短语"表示"……是……中最……的"。 如,Tom is the tallest in his class./of all the students. ②"主语+be+ one of the+形容词最高级+复数名词+in/of短语"表示"…是……中最……之一"。 如,Beijing is one of the largest cities in China. ③序数词+最高级 Hainan Island is the second largest island in China. 练习:I.写出所给词的反义词。 1.young________ 6.better___________ 2. white________ 7. longer__________ 3. big__________ 8. thinner_________ 4. left_________ 9. far_____________ 5.fast_________ 10. light__________
