比较级前通常不用冠词,但有时也用,这主要见于以下情形：
1.当比较级后接名词时,比较级前可能用冠词,此时的冠词不是修饰比较级,而是修饰其后的名词.如：
Which of them is the better choice?—Well,it’s hard to tell.他们谁是更合适的人选?——嗯,这很难说.
Some of the more time-consuming jobs can now be done by machines.有些更费时间的工作现在可以用机器做了.
但是,若受比较级修饰的名词为表泛指的复数名词或不可数名词,则仍不用冠词.如：
He’s got more money than the rest of us (put) together.他的钱比我们大家的加在一起的总数还多.
Fewer people write with their left hand than with their right.用左手写字的人比用右手的少.
2.当要特指两者中“较(更)……”时,比较级前通常要带定冠词,此时可视为比较级后省略了有关的名词或代词one,即定冠词实为修饰被省略的名词或代词one.如：
Which of the two methods is the better?这两种方法哪一种更好?
Of the two possibilities,this is more likely than that.两个可能性中,后者比前者更可能.
3.在比较级前用the表示程度(通常有表示原因、理由或条件的短语或从句).如：
He’s had a holiday and looks the better for it.他度假之后,气色好多了.
I love him all the more for his faults.正因为他这些缺点,所以我越发爱他.
4.用于“the+比较级,the+比较级”,表示“越……越……”.如：
The younger you are,the easier it is to learn.年纪越轻,学习越容易.
The better I know her,the more I admire her.我对她越了解,我就越爱慕她.
The more money you make,the more you spend.你挣的钱越多,花的钱也越多.
5.当by far用于修饰比较级且置于其前时,比较级前要用the.如：
He is by far the cleverer than her.他比她聪明得多.
It’s quicker by far to go by train.坐火车去要快得多.
注：与比较级连用,通常要放在比较级之后,若放在比较级前,则比较级通常应带有冠词.如：
He is cleverer by far than her.
It’s by far the quicker to go by train.
