suit,suitable 和 fit 的用法区别
1）suitable 的动词形式是 suit,与动词 fit 都有“合适”之意,但也有区别.以衣服为例,fit 是指大小尺寸合适,而 suit 则是表示衣服穿着很好看,包括款式和花式都合适.如：
（1）Do you think this style suits me?你觉得这种款式适合我穿吗?
（2）These shoes don't fit me—have you got a larger size?
这鞋我穿着不合适——你们有大一点的吗?
（3）It doesn't suit you to have your hair cut short.你头发剪短了不好看.
（4）The seven o'clock train will suit us very well.七点钟的火车对我们正合适.
2) 形容词 suitable 后可接 for sth.和 to sb..如：
（1）I don't think I should be suitable for the post.我认为自己不适合这个职位.
（2）The work was not suitable to me.那工作不适合我.
3) 形容词 fit 后只能接介词 for,且句子主语多用人表示.
（1）The new manager isn't fit for his position.新经理不胜任他的职务.
（2）would be months before he was fit for work.要过几个月他才能适合工作.
(3) My sister is just fit for a job as teacher.我妹妹正适合教师这一工作.
（4）The prime minister was a wise,honest man who was more fit for his office
anyone else.
首相是个聪明、诚实的人,比任何人都称职.
