Which is the larger country, Canada or Australia? She is taller than her two sisters. She is the taller of the two sisters. （3）可修飾比較級的詞1）a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even等 2）還可以用表示倍數(shù)的詞或度量名詞作修飾語。 3）以上詞(除by far)外，必須置于比較級形容詞或副詞的前面。 典型例題1） - Are you feeling _? - Yes，Im fine now. A. any well B. any better C. quite good D. quite better 答案：B. any 可修飾比較級，quite修飾原級，well的比較級為better. 2）The experiment was_ easier than we had expected. A. more B. much more C. much D. more much 答案：C. much可修飾比較級，因此B，C都說得通，但easier本身已是比較級，不需more，因此C為正確答案。 3）If there were no examinations, we should have _ at school. A. the happiest time B. a more happier time C. much happiest timeD. a much happier time 答案：D。 重點難點詳解（1）many ,old 和 far 1) 如果后接名詞時， much more +不可數(shù)名詞 many more +可數(shù)名詞復數(shù) 2) old 有兩種比較級和最高級形式: - older/oldest - elder/eldest 只用于兄弟姐妹的長幼關系。 - My elder brother is an engineer. - Mary is the eldest of the three sisters. 3) far 有兩種比較級，farther，further. 在英語中兩者都可指距離。 在美語中，father 表示距離，further表示進一步。 I have nothing further to say. （2）the + 最高級 + 比較范圍1) The Sahara is the biggest desert in the world. 形容詞最高級前通常必須用定冠詞 the，副詞最高級前可不用。 形容詞most前面沒有the，不表示最高級的含義，只表示“非常”。 It is a most important problem. = It is a very important problem. 注意： 使用最高級要注意將主語包括在比較范圍內(nèi)。 - (錯) Tom is the tallest of his three brothers. - (對) Tom is the tallest of the three brothers. 2) 下列詞可修飾最高級 by far, far, much, mostly, almost - This hat is nearly / almost the biggest. 注意： a. very可修飾最高級，但位置與much不同。 - This is the very best. - This is much the best. b. 序數(shù)詞通常只修飾最高級。 - Africa is the second largest continent. 3) 句型轉(zhuǎn)換： - Mike is the most intelligent in his class. - Mike is more intelligent than any other students in his class. 4) “否定詞語+比較級”，“否定詞語+ so as”結(jié)構(gòu)表示最高級含義。 Nothing is so easy as this. =Nothing is easier than this. =This is the easiest thing. （3）和more有關的詞組1) the more the more 越就越The harder you work，the greater progress youll make. 2) more B than A = less A than B 與其說A不如說B He is more lazy than slow at his work. = He is less slow than lazy at his work. 3) no more than 與一樣，不比多 The officials could see no more than the Emperor. no less than 與一樣 He is no less diligent than you. 4) more than 不只是，非常 She is more than kind to us all. 形容詞和副詞比較級和最高級習題一、選擇填空1.
