as+形容词或副词原级+as 1）在否定句或疑问句中可用 so… as。 He cannot run so/as fast as you. 2）当 as… as 中间有名词时采用以下格式。 as +形容词+ a +单数名词 as + many/much +名词 This is as good an example as the other is. I can carry as much paper as you can.. 3）用表示倍数的词或其他程度副词做修饰语时，放在 as 的前面。 This room is twice as big as that one. Your room is the same size as mine. 4) 倍数+ as + adj. + as<=>倍数+ then + of This bridge is three times as long as that one. This bridge is three times the length of that one. Your room is twice as large as mine. Your room is twice the size of mine. 比较级形容词或副词+than You are taller than I. They lights in your room are as bright as those in mine. 注意： 1）要避免重复使用比较级。 (错) He is more cleverer than his brother. (对) He is more clever than his brother.
(对) He is clever than his brother. 2）要避免将主语含在比较对象中。 (错) China is larger that any country in Asia. (对) China is larger than any other countries in Asia. 3）要注意对应句型，遵循前后一致的原则。 The population of Shanghai is larger than that of Beijing. It is easier to make a plan than to carry it out. 4）要注意冠词的使用，后有名词的时候，前面才有可能有名词。 比较：Which is large, Canada or Australia? Which is the larger country, Canada or Australia? She is taller than her two sisters. She is the taller of the two sisters.
可修饰比较级的词 1）a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even 等 2）还可以用表示倍数的词或度量名词作修饰语。 3）以上词(除 by far)外，必须置于比较级形容词或副词的前面。 典型例题: 1）---- Are you feeling ____? ---- Yes，I'm fine now. A. any well B. any better C. quite good
D. quite better
答案： any 可修饰比较级， B. quite 修饰原级， well 的比较级为 better. 2）The experiment was____ easier than we had expected. A. more B. much more C. much D. more much
答案：C. much 可修饰比较级，因此 B，C 都说得通，但 easier 本身 已是比较级，不需 more，因此 C 为正确答案。 3）If there were no examinations, we should have ___ at school. A. the happiest time C. much happiest time 答案：D。 B. a more happier time D. a much happier time
many, old 和 far 1) 如果后接名词时， much more +不可数名词 many more +可数名词复数 2) old 有两种比较级和最高级形式: older/oldest 和 elder/eldest。 elder，eldest 只用于兄弟姐妹的长幼关系。 My elder brother is an engineer. Mary is the eldest of the three sisters. 3) far 有两种比较级，farther，further. 在英语中两者都可指距离。 在美语中，father 表示距离，further 表示进一步。 I have nothing further to say.
1) The Sahara is the biggest desert in the world. 形容词最高级前通常必须用定冠词 the，副词最高级前可不用。 形容词 most 前面没有 the，不表示最高级的含义，只表示"非常"。 It is a most important problem. =It is a very important problem. 注意：使用最高级要注意将主语包括在比较范围内。 (错)Tom is the tallest of his three brothers. (对)Tom is the tallest of the three brothers. 2) 下列词可修饰最高级，by far, far, much, mostly, almost This hat is nearly / almost the biggest. 注意： a. very 可修饰最高级，但位置与 much 不同。 This is the very best. This is much the best. b.序数词通常只修饰最高级。 Africa is the second largest continent. 3) 句型转换： Mike is the most intelligent in his class. Mike is more intelligent than any other students in his class. 4) "否定词语+比较级"，"否定词语+ so… as"结构表示最高级含义。 Nothing is so easy as this. =Nothing is easier than this.
=This is the easiest thing.
和 more 有关的词组 1) the more… the more…越……就越…… The harder you work，the greater progress you'll make. 2) more B than A 与其说 A 不如说 B less A than B He is more lazy than slow at his work. = He is less slow than lazy at his work. 3) no more… than… 与……一样……，不比……多 The officials could see no more than the Emperor. no less… than…与……一样…… He is no less diligent than you. 4) more than 不只是，非常 She is more than kind to us all. 典型例题 1）The weather in China is different from____. A. in America B. one in America C. America
D. that in America 答案：D. 本题意为"中国的天气比美国热。"比较的是天气而不是国家，C 不能选。A 没有名词，后句成分不全，排除。B 和 D 中，B 中的 one 常 用来代替可数名词，而 that 可车以代替不可数或抽象名词，所以选 D。 2）After the new technique was introduced，the factory
produced ___ tractors in 1988 as the year before. A. as twice many twice many as 答案 C. 此句意为"这个厂 1988 能生产的拖拉机是往年的两倍"。表示倍 数用"倍数+ as + 形容词原形+ as +比较对象"的句型。所以此句答案为 C。 This ruler is three times as long as that one B. as many twice C. twice as many D.
