(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：B. any 可修饰比较级，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 B. a more happier time C. much happiest time D. a much happier time 答案：D。 比较级和最高级一般都要一起讲吧 the + 最高级 + 比较范围 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. 参考资料：
