11、kindly 热心肠的likely可能的leisurely悠闲的ugly长得丑的brotherly兄弟般的monthly每月的 earthly尘世的2只作以“a”开头的很多形容词只能做表语：afraid害怕的alike相象的awake醒着的alone单独的，惟的alive活着的ashamed羞愧的 asleep睡着的aware意识到的、察觉到的well健康的content满意的unable无能的3只作前置定语的形容词earthen泥土做的，大地的daily每日的latter后面的golden金子般的weekly每周的inner 里面的silken丝一般的monthly每月的outer外面的wo

13、s great difficulty when it comes to specifics.二.形容词与副词的比较级与最高级L考比较级时，考生应把握：1）形容词和副词比较级的形式是否和比较连词对应出现，即是否符合原级比较及比较级的结构。如：Do you enjoy listening to records?

15、t of last year*s（前后相比的应该是今年和去年注册参加的人数the number of故代替它的应该是单数指示代词“that”，而不能选择B, those是指代participants,不是同类对比，答案为D。Young readers, more often than not, find the novels of dickens far more exciting than Thackerays.3）比较级与倍数词关系及其位置原级结构中可插入表达倍数的词，表示为“为.若干倍”，当与有表示倍数比较的词在一起时候等，他们的位置是，倍数词+asas，或倍数词+moreihan，但a

16、gain 一般放在原级词之后,即“as+原级+again+as”.如:Smoking is so harmful to personal health that it kills people each year than automobile accidents.A. seven more times B. seven times moreC. over seven times D. seven times（答案为B.“Do you regret paying five hundred dollars for the painting?,ntNo, I would gladly have p

23、 as it is B. the same is C. so is D. and so is（答案为C.2.最高级形式应注意的问题：1）最高级比较范围用介词in, over, of, amongoin,（all） over 用于在某一范围内的比较，如：in China, all over the world.of, among用于在同一群体内同类事物的比较，如：among the teachers, of the four dresses.注意：among相当于one of，不说among all。这一点考生应与汉语表达区别开来如：all visible lights, red light h

24、as the longest and violet the shortest wavelength.A. Among B. OfC.For D.To 答案为 B.2）比较级形式表示最高级意义时，比较对象的范围应用：any other +单数名词the other +复数名词the othersanyone/anything else上述词是用业将比较级结构转变成最高级意义的关键词语，切不可遗漏，尤其是other,否则会造成逻辑混乱的错误。如不能说：John runs faster than anyone.注意与汉语表达的不同。3） most可以用来修饰形容词或副词，意思相当于very,用法区分

25、单复数，但不能用定冠词the,如：a most interesting book, most expensive restaurants,要注意与 u the +形容词最高级+of +名词”的结构表示的最高级的区别，如：He spoke in the warmest of voicesThey have been most kind to meBasketball is the most popular of sports in this country.Chinese is the most difficult of languageChinese is a most difficult l

28、al, perfect, excellent, thorough, complete.四 .平行结构与比较级平行结构很多情况卜.是由形容词或副词的比较级或者暗含比较意味的连词引导的。如：The ideal listener stays both inside and outside the music at the moment it is played and enjoys it almost as much as the composer at the moment he composes.大多数情况下平行结构都是具有一定的比较含义的，有的是递进对比not only-but （also）;

29、 preferto；rather than 有的是同类对比：and; but; or; both and；eitheror；neithernor平行结构测试时候注意以下几点：1 .注意比较结构中相比较的内容在语法形式上是否相同。如：It is better to die one*s feet than.A.living on ones knees B.live on ones kneesC.on one*s knees D.to live on ones knees（答案为D.Despite the temporary difficulties, the manager prefers inc

33、 so sweet as that earned by his own labor.2. one的指代作用one指代带不定冠词的单数可数名词，复数为ones。the one指代带定冠词的单数可数名词。如：A good writer is who can express the commonplace in an uncommon way.A. that B.he C.one D.this答案为C.3. do的替代作用。do代替动词，注意数和时态的变化。如：For him to be re-elected, what is essential is not that his policy wor
