look for和look for的用法

Seek 一般用于抽象意义,有时也表示渴望得到某一具体的东西,是比较正式的书面用法.可构成seek for,seek after等短语,作“寻找,设法得到”等解.其后可接动词不定式,此时表示“试图,企图”.如：
They seek information from various sources.他们从各种来源收集信息.
look for 强调找的过程.如：
He is looking for his dictionary bought yesterday.他在找昨天买的那本词典.
附：它们与search,hunt for,find,find out 的区别

Search 通常指对某处、某地进行搜查或搜索；对人时为“搜身”.常接for构成短语search for,作“寻找；搜寻”解,其对象多为一个或一批人或物,如找矿,找资料,找文件,找工作等.它强调寻找的行为,不着重结果.如：
The police searched him but nothing was found on him． 警方搜了他的身,但什么也没找到.
They are searching for the missing child．他们在寻找失踪的孩子.
hunt for 指竭力搜寻,其搜寻对象往往是某种迫切需要的东西或人.如：
This is just the thing I am hunting for.这正是我在找的东西.
They’ve been hunting for you everywhere.他们一直在到处找你.

Find 通常强调找的结果.其后可跟名词、复合结构或that从句.如：
Use your head,then you'll find a way.开动脑筋,就会有办法的.
He found his home village unchanged.他发现家乡还是老样子.
find out 通过观察、调查、询问等方式找出（原因等）,或发现（秘密、错误）情况等,其后一般跟名词、代词或从句.如：
Have you found out his address?你查到他的住址了吗?
Please find out when the train leaves.请打听一下火车什么时候开.

Look for“寻找”强调动作, 和search意思一样 
如："If you find any mistake,please correct it." 
"如发现有错,请你改正." 
looking for my gloves.
找我的手套
