than的难点用法
一、后接人称代词用主格还是宾格
由于than既可用作连词也可用作介词,所以当后接人称代词时,可用主格也可用宾格.通常认为在正式文体中多用主格,在口语或非正式文体中多用宾语.如：
Everyone here is taller than I[me].这儿的每一个人都比我高.
Her sister swims faster than she[her].她姐姐游泳比她快.
但是,若人称代词之后跟有动词,则只能用主格.如：
Everyone here is taller than I am.这儿的每一个人都比我高.
Her sister swims faster than she does.她姐姐游泳比她快.
注意：有时用主格或宾格会导致意思的变化.比较：
I love you than he(likes you).我比他更爱你.
I love you than(he likes)him.我爱你胜过爱他.
二、后接动词用不定式还是-ing分词
1.当连接两个非谓语动词时,通常应使用一样的形式.如：
It is much easier to get into debt than to get out of it.借债容易还债难.
He likes playing chess than watching TV.与看电视相比,他更喜欢下棋.
比较：
He thinks it is safer to drive himself than(to)let me drive.
He thinks that driving himself is safer than letting me drive.他认为他自己开车比让我开车要更安全些.
2.若不是连接两个非谓语动词,则其后出现的动词通常用-ing分词形式(虽然也可用不定式,但不如用-ing分词普通).如：
There are worse calamities than failing your driving test.比起你驾驶考试不合格来说,更大的灾难还多着呢.
Nothing gives me pleasure than listening to Mozart.再没有比听莫扎特的乐曲更让我高兴的事了.
Nothing is unpleasant than finding[to find]insects in your bath.最使人不快的是在浴室里发现有虫子.
三、引导比较状语从句的时态问题
若than引导的比较状语从句与主句动作不一致,可以根据情况使用适当的时态形式.如：
He drives faster than he did a year ago.他开车比一年以前快了.
The house is rather bigger than we thought.这所房子比我们想的大得多.
若主句为将来时,than引导的从句可用现在时态表示将来,也可直接使用将来时态.如：
We’ll probably drive faster than you do[will].我们开车可能会比你们快.
四、引导比较状语从句的倒装问题
than引导比较状语从句时,从句语序通常不需倒装,但在正式文体中,有时也可倒装.如：
City dweller have a higher death rate than country people do.
City dweller have a higher death rate...
