rather和than的用法！！！

rather的用法
一、rather作副词,意为"宁愿;宁可"。作此意解的rather常和would / had连用,构成固定短语。would / had rather…than译为"宁愿……而不愿" ,应该特别注意此短语的否定构成及其后接的动词形式。如:
He would rather have the small one than the large one. 他宁愿要一个小的,而不要大的。
would / had rather 后接从句时,从句中的谓语动词用虚拟语气。如:
I would / had rather you posted the letter right away, 我倒希望你把这封信立即发出。 二、rather作副词用时,意为"更确切地"。 此用法的rather常用在or rather这一短语中,表示想要纠正已经说过的话,或欲使已说过的话更确切。如:
He worked till late last night, or rather, early in the morning. 他一直工作到深夜,或者更确切地说,到今天凌晨。
　三、rather作副词用时, 还可作"相当;颇;有点儿"解。如:
You've done rather well.你做得相当好。
rather大多数情况下用于非正式文体,可放在不定冠词前,也可放在不定冠词之后,还可以和动词连用,可以修饰比较级,还可和too连用。如：
This book is rather too difficult for the beginners.这部书对初学者来说太难了。
四、rather than 的用法。
rather 不仅是一个表示程度的副词,还能用来表示选择,意为"而非;(与其……)倒不如"。rather than 经常用在"平行结构"里,即连接两个对等成分。
I always prefer starting early, rather than leaving everything to the last minute. 我总是愿意早开始而不愿意把所有事情都留到最后。

than的用法
既可连接名词、代词、形容词、副词， 又可以连接动词； 既可用来强化肯定， 又可加强否定语气。下面就than的语法功能， 举些例子说明。 　　
一、than用于比较 　　
A＞B
1. Your father is older than mine.
2. Easier said than done.
说来容易做来难。(谚语)（这一表达法是It is easier said than done的省略形式.)
3. You love her more than I / me.
注意：than I 是主语对比：你比我更爱她。
than me是主句之宾语与比较状语从句之宾语：
你爱她胜过你爱我。

　　4. This kind of computer is less expensive than that one.
　　这种电脑没有那种贵。
