⒊使用形容词、副词的比较等级时要注意的几个问题
⑴在as-----as之间只能使用原级形容词（副词）。例如：
误：I have as less money as you do.
正：I have as little money as you do.
⑵切忌采用双重比较
比较级前可以用表示程度的修饰语来表示强调或程度，但不可用more加比较级形式。例如：
误：His health is more worse than before.
正：His health is worse than before.
⑶应避免自我比较
使用比较级时，进行比较的双方必须是互相分离、互不包含的独立概念或事物，否则比较就不合逻辑。例如：
误：Bamboo probably has more uses than any plant in the world.
正：Bamboo probably has more uses than any other plant in the world.
[附]比较的另一方如果是不定代词anyone, anything, 前面不能加other, 而要在其后加else. 例如：
She studies harder than anyone else in her class.
但是，若比较的双方不属于同一范围，句中则不加other。例如：
She runs faster than any boy in her class.
⑷表示“两者中较-------”时，比较级前要加the。例如：
The older of the two noblemen took a light and led me into a back room.
⑸被比较的双方必须具有可比性。例如：
误：There are more students in this school than that school.
正：There are more students in this school than in that school.
⑹连词than后使用代词主格和宾格有时意义不同。例如：
①I know you better than he.我比他更了解你
②I know you better than him.我对你的了解比对他的了解更透彻些（或：“我比他更了解你”，此时与①同义）。
⑺使用最高级时，主语不可被排除在最高级所指的范围之外。例如：
误：He is the tallest of all his brothers.
正：He is the tallest of all the brothers.
⑻most前面加不定冠词a/an，或者不加冠词修饰形容词时，它的意思等于very。此时， most已失去最高级的意义。试比较：
a most interesting film(一部很有趣的电影) / the most interesting film(最有趣的电影)
