Asas结构的总结 一: 判断其中的哪种词性, 必须熟练掌握good, well的区别 二: 倍数的问题 三: asas/ as soon as一就/ as soon as possible 尽可能快的 的意思区别 四: as well- as well as 的区别 As well= too He does as well as his brother, as well. 他也像他的兄弟那样做得一样好 五: as as的否定形式 中国登月不像美国那么早 China doesnt land on the moon as/so early as U.S.A 比较级: 他比她更酷 He is cooler than her 比: than 更: 在英语中有三个写法 She is smarter than him 她比他更聪明 She is more beautiful than him.她比他更漂亮 She does better than him. 她做得比她更好 汉语中的一个”更”, 在英语中, 根据形容词和副词 本身的原型,产生三大类的变形 Red-redder(单元音+er) Beautiful-more beautiful (多元音: more+原型) 特殊词 所有单元音, 其后都配 er smart-smarter 辅元辅,双写 redredder; hothotter 这四类 ble; ple; ow; er 双元音, 还是 er Clevercleverer; narrownarrower; 狭窄的 ableabler有能力的; simplesimpler简单的; heavyheavier更重的 所有的多元音,双元音: more+原型 quiet more quiet ; beautiful more beautiful 特殊变形: good/well betterbest; bad/badly/illworseworst; many/much moremost; little/a little lessleast; few/ a few fewerfewest Old olderoldest; oldeldereldest Farfartherfarthest; farfurther-furthest 比较级的基本知识: 结构: It sounds good 它比那个更好听 It sounds better than that 他比她更强壮 He is strong He is stronger than her. 他喝得比他高 比较级的难点1. more 1. 构成比较级,本身无意义 She is more beautiful than her. 2. many, much 的比较, 本身有意义 She has many books. 例:她的书比他的书多 She has more books than his 3. no more= not any more不再 4. more or less 或多或少 5. more and more 越来越多; less and less越来越少; redder and redder 越来越 红 6.the 比较级, the 比较级(the 必须 放于句首) 你越瘦,冬天你觉得越冷 The thinner you are, the cooler you feel in winter. 7. one more= another one 再来一个 I need _ candle. 我还得需要一只蜡烛 4.最高级和比较级中意思相同的转化 他比班里其他的人都高 他在班里最高 He is taller than any other student in the class. He is the tallest in the class. 解题思路: 一:分清比较和最高 二:在比较中, than 后只接any other 5.比较级的修饰问题 Much/ a little/ too/ far/still/even对比较级 修饰 He is stronger than him他比他壮 He is much/ too/ far stronger than him他 比他壮得多 His handwriting is _ than her Far good; far best; much better; more better 6.到底什么是比较级 Hangzhou is a _ beautiful city More; very; much more; much 解题思路: 比较级必须有比较的对象, 例:今天比昨天热 今天比较热 经典汉语:小腿肚子上挂水平-比较高的水平(比 脚高的水瓶) The book he bought in the book store was _ than that he brought from his brother better; best; far; far good She is my elder sister. She is my older sister. 2误 析 elder 和eldest是用来指家庭中兄 弟姐妹的长幼关系，而older, oldest 则是 指岁数大多少，如：She is three years older than I. Im tired. I cant go further. Im tired. I cant go farther. 1误 析 far有两个比较级 farther 较远的， further 进一步的，如：Do you need any further explanation? 你需要进一步的解释 吗?当然它也有两个最高级。farthest和 furthest. He is very higher than I am. He is much higher than I am. 1误 析 much可以用来修饰比较级，而 very则用来修饰形容词原级，如：Im very tired. She is not half as clever as her brother. She is not as half clever as her brother. 2误 析 在asas结构中要将修饰形容词 的数量词倍数及nearly, almost, exactly 等置于第一个as之前。 Who is taller of the two? Who is the taller of the two? 1误 析 两者的比较级之前要加定冠词。 I have less books than Tom. I have fewer books than Tom. 1误 析 less 是 little的比较级，而fewer是 few的比较级。less后应加不可数名词而 fewer后是可数名词。 There are three girls in my group. The cleverest is Mary. There are three girls in my group. The cleverer is Mary. 2误 析 在两者之间应用比较级，在三者之 间或三者以上的范围内应用最高级。 The boy sat there as quiet as his sister. The boy sat there as quietly as his sister 1误 析 asas的用法要注意的是： 在其中间应加形容词或副词的原级，而 不可加比较级，也有的语法书中称为同级 比较。 要根据句意决定是加形容词还是副词， 这要看它具体是修饰动词还是名词而定， 如：He is as good as his friend. The harder you study, and you can learn more The harder you study, the more you can learn. 1误 析 英文中如果要表达越来越怎样，在初中 范围有两种表达法： 比较级+and+比较级。 定冠词+比较级，如：The nights are getting longer and longer。 要注意的是多音节 形容词的比较级前要加more，这样的用法是： more and more 加形容词，如：The girl is growing more and more beautiful. as Studying physics is not so interesting as to learn English. Studying physics is not so interesting as learning English. 1误 析 在作比较时，英语一般要求对比的两部 分结构应一致。如用动名词，应都用动名词， 用不定式时则都用不定式。但有时在后一个不 定式前的符号to可以省略。如：To repair the old one is as much expensive as (to) buy a new one. The girl is more cleverer than the boy. The girl is much more clever (much cleverer) than the boy. 1误 析 clever有两个比较级：cleverer和 more clever,要注意的是不能用比较级来 修饰比较级。 clever的两个比较级也各有不同之处，如 用在两种不同性质的比较时多用more clever,如：He is more clever than honest. (他的聪明要远远超过其诚实。) The boy is the tallest to the three. The boy is the tallest of the three. 1误 析 最高级的范围要用of加复数形式或 加集合名词。 This dictionary is the much best one of the English Chinese dictionaries. This dictionary is much the best one of the English Chinese dictionaries. 1误 析 在修饰最高级时应用 far/by far/much 加the加最高级。但very例外， 如：He is the very best player in the team. Shanghai is bigger than any other cities in China. Shanghai is bigger than any other city in China. 1误 析 在比较级中表示比较对象时如用 any other其后一般要加单数名词。 Most of the stories in this book are written in English. Most of stories in this book are written in English. Most stories in this book are written in English. 2误 析 “大多数“一词的表达法有most of the +n ，或most+n。当用前一种结构时，其后面的定 冠词不可少。 The temperature of that room is higher than that of this room. The temperature of that room is higher than this room. 2误 析 比较级用于两句话之间时，比较的部分 不可省略掉，但为了避免重复，一般都要用that 代替前面的单数名词，而用those代替前面的复 数名词，如：The books in that box are bigger than those in this box。 1 I think Chinese is than maths. . interesting B more interesting C. most interesting D. the most interesting 答案 B. 析 在有than作比较的句子中应用adj的比较 级。 3 The Huang He River is one of in China. A. The long river B. the longest river C. the longest rivers D. the longer river 答案 C. 析 在one of + 定冠词+最高级之后的 名词应用复数形式。 4 It was yesterday than today. A. hot B. hoter C. hotter D. the hottest 答案 C. 析 用than表达比较的句中应用比较级 。 5 Which subject do you like , English Chinese or maths? A. best B. well C. better D. good 答案 A. 析 在两者之间应用比较级，而在三者 之间或三者以上用最高级。 6 she eats, shell be. A. Morefat B. The morefatter C. Morethe fatter D. The morethe fatter 答案 D. 析 the+比较级表示“越来越“本句 应译为：她吃得越多，她就会越胖。 7 I dont think English is Chinese. A. as important as B. not important as C. not so important D. important as 答案 A. 析 think+宾语从句时，应采用否定主句的 形式，如：中文讲，“我认为你不对“，英文应为 ：“我不认为你对“。 I dont think you are right. 所以不能选答案B。而C、D均为不正确的表达 法。 8 Which is , Li Leis box or Guo Meimeis box? A. heavy B. heavier C. more heavier D. the heaviest 答案 B. 析 两者之间用比较级，三者或以上用 最高级。 Heavy heavier; clever- cleverer 9 You look than before， why? A. more thin B. more thinner C. much more thin D. much thinner 答案 D. 析 多音节形容词才用more或most加 adj来表示其比较级或最高级，而thin的比 较级为thinner。 10 Ill work I can. A. so hardly as B. so hard as C. as hardly as D. as hard as 答案 D. 析 hard可用作adj和adv， 如：The desk was made of hard wood 又如：It is raining hard。 而 hardly 是adv，其词义是“几乎不“， 如：Hardly did I sleep last night. 我昨晚几乎没 有睡觉。 而且hardly用于句首时要采用倒装语序。 asas
