[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。
[误] There are three girls in my group. The cleverer is Mary.
[正] There are three girls in my group. The cleverest is Mary.
[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。
[误] The boy sat there as quiet as his sister.
[正] The boy sat there as quietly as his sister.
[析] as…as的用法要注意的是：①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。②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.
[误] The harder you study, and you can learn more.
[正] The harder you study, the more you can learn.
[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：①比较级+and+比较级。②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.
[误] Studying physics is not so interesting as to learn English.
[正] Studying physics is not so interesting as learning English.
[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.
[误] The girl is more cleverer than the boy.
[正] The girl is much more clever (much cleverer) than the boy.
[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。)
[析] The boy is the tallest to the three.
[正] The boy is the tallest of the three.
[析] 最高级的范围要用of加复数形式或加集合名词。
[误] This book is one of the most useful dictionary.
[正] This book is one of the most useful dictionaries.
[析] 在one of 后面最高级形容词后要加可数名词复数。
[误] This dictionary is the much best one of the EnglishChinese dictionaries.
[正] This dictionary is much the best one of the EnglishChinese dictionaries.
[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.
[误] Shanghai is bigger than any other cities in China.
[正] Shanghai is bigger than any other city in China.
[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。
[误] Most of stories in this book are written in English.
[正] Most of the stories in this book are written in English.
[正] Most stories in this book are written in English.
[析] "大多数"一词的表达法有most of the +名词，或most+名词。当用前一种结构时，其后面的定冠词不可少。
[误] The temperature of that room is higher than this room.
[正] The temperature of that room is higher than that of this room.
[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.
[误] He is no more here. Maybe he is at home.
[正] He is no longer here. Maybe he is at home.
[析] no more在现代英语中多译为："从此再也不会了",如：His voice is no more here. 他已经去世了，他的声音不可能再出现了。而用no longer 表达目前的状态。要注意下面几组句子的实际含意： This room is no cleaner than that one.即两间屋子都不干净。(两者都不干净) This room is not cleaner than that one,即这屋子不如那间干净。(前者不如后者干净。即一间干净，一间不干净。)
