for的用法完全归纳
用法1:(表目的)为了。如:
They went out for a walk. 他们出去散步了。
What did you do that for? 你干吗这样做?
That’s what we’re here for. 这正是我们来的目的。
What’s she gone for this time? 她这次去干什么去了?
He was waiting for the bus. 他在等公共汽车。
在通常情况下,英语不用for doing sth 来表示目的。如:他去那儿看他叔叔。
误:He went there for seeing his uncle.正:He went there to see his uncle.
但是,若一个动名词已名词化,则可与for 连用表目的。如:
He went there for swimming. 他去那儿游泳。(swimming 已名词化)
注意:若不是表目的,而是表原因、用途等,则其后可接动名词。
用法2:(表利益)为,为了。如:
What can I do for you? 你想要我什么?
We study hard for our motherland. 我们为祖国努力学习。
Would you please carry this for me? 请你替我提这个东西好吗?
Do more exercise for the good of your health. 为了健康你要多运动。
(1)有些后接双宾语的动词(如buy, choose, cook, fetch, find, get, order, prepare, sing, spare 等),当双宾语易位时,通
常用for 来引出间接宾语,表示间接宾语为受益者。如:
She made her daughter a dress. / She made a dress for her daughter. 她为她女儿做了件连衣裙。
He cooked us some potatoes. / He cooked some potatoes for us. 他为我们煮了些土豆。
注意,类似下面这样的句子必须用for:
He bought a new chair for the office. 他为办公室买了张新办公椅。
(2) 注意不要按汉语字面意思,在一些及物动词后误加介词for:
他们决定在电视上为他们的新产品打广告。
误:They decided to advertise for their new product on TV.
正:They decided to advertise their new product on TV.
注:advertise 可用作及物或不及物动词,但含义不同:advertise sth=为卖出某物而打广告;advertise for sth=为寻某物而打广告。如:advertise for a job=登广告求职。由于受汉语“为”的影响,而此处误加了介词for。类似地,汉语中的“为人民服务”,说成英语是serve the people,而不是serve for the people,“为某人的死报仇”,说成英语是avenge sb’s death,而不是avenge for sb’s death,等等。
用法3:(表用途)用于,用来。如:
Knives are used for cutting things. 小刀是用来切东西的。
This knife is for cutting bread. 这把小刀是用于切面包的。
It’s a machine for slicing bread. 这是切面包的机器。
The doctor gave her some medicine for her cold. 医生给了她一些感冒药。
用法4:为得到,为拿到,为取得。如:
He went home for his book. 他回家拿书。
He went to his friend for advice. 他去向朋友请教。
She often asked her parents for money. 她经常向父母要钱。
We all hope for success. 我们都盼望成功。
Are you coming in for some tea? 你要不要进来喝点茶?
用法5:给(某人),供(某人)用。如:
That’s for you. 这是给你的。
Here is a letter for you. 这是你的信。
Have you room for me there? 你那边能给我腾出点地方吗?
用法6:(表原因、理由)因为,由于。如:
I am sorry for it. 对不起。
Thank you for coming to see me. 谢谢你来看我。
I couldn’t speak for laughing. 我笑得说不出话来。
He couldn’t sleep for joy. 他高兴得不能入睡。
【用法说明】有些表原因的特殊结构不宜用介词for 来引出,而用其他介词。如:
他由于努力工作而加了工资。
误:For the result of his hard work, he got a pay rise.
正:As a [the] result of his hard work, he got a pay rise.
注:as a [the] result of 是习语,意为“由于……的结果”。
因为母亲不在家,她只好自己做饭。
误:For Mother (being) away, she had to cook the meal herself.
正:With Mother (being) away, she had to cook the meal herself.
注:“with+宾语+宾语补足语”可用来表示原因,此时的with 不能换成for。类似地,下例中的with 也不能换成for:With all this work to do, I don’t know if I’ll have time to go out. 有这么多工作要做,我不知是否有时间出去。
我们祝贺你的成功。
误:We congratulate you for your success.
正:We congratulate you on your success.
注:congratulate 后习惯上接介词on 表示原因。
用法7:(表目标、去向)去。如:

They set off for the shops. 他们买东西去了。
Is this the train for Shanghai? 这是开往上海的火车吗?
Passengers for Tianjing must change at Beijing. 去天津的旅客必须在北京换车。
【用法说明】比较for 与to,两者均可表示目的地,注意以下区别:
for 通常与leave, start, set out, set off, head, steer, depart, be bound, be destined 等动词连用,而to 则通常与come, drive, fly, get, go, lead, march, move, return, ride, run, travel, walk 等动词连用。如:
We departed for London at 10 am. 我们上午10点动身去伦敦。
Then we drove to the station. 然后我们就开车去了车站。
有时,同一个动词(如sail)两者均可连用,但含义稍有差别:用for 通常只表示向着某目的地那个方向,并不强调到达的意思;而to 含有到达某目的地的意思。如:
They sailed for Shanghai. 他们开船驶往广州。
They sailed to Shanghai. 他们开船驶至广州。
若与名词连用,也有类似区别。如:
There will be a train for Wuhan. 有开往武汉的火车。(仅表示向武汉方向,但在武汉未必是停靠站)
There will be a train to Wuhan. 有开往武汉的火车。(开往武汉方向,且在武汉停靠)(R56)
顺便说一句,也有的辞书持几乎相反的观点,认为for 与to 表示目的地时,for 表示的是预定目的地,而to 表示的是假设将会到达的目的地。
用法8:(表时间、距离、数量等)达,计。如:
I’m going away for a few days. 我要走开几天。
I’ve been here for ten years. 我来这儿有10年了。
He walked for ten miles. 他走了10英里路。
The shop sent me a bill for $50. 商店给我送来了一张50美元的账单。
【用法说明】for 用于表示时间或距离的长度(尤其是紧跟在动词之后)时,有时可省略。如:
The meeting lasted (for) three days. 会议持续了3天。
They walked (for) fifty miles. 他们走了50英里。
但是当for 短语位于句首或在否定句中时, for 通常不宜省去。如:
For ten years he lived here. 他在这里住过10年。
We have not heard from him for a long time. 我们很久没收到他的来信了。
用法9:对,对于。如:
Eggs are good for you. 鸡蛋对你有好处。
Reading in bed is bad for your eyes. 躺在床上看书对你的眼睛不好。
Fortunately for me, the train was also late. 我很走运,火车也晚点了。
【用法说明】关于for 与to 表示“对……来说”时的区别,参见to。
用法10:(表适合)适于,适合。如:
Do you have any books for children? 你有适合小孩子看的书吗?
He is the very person for the work. 他是最适合做这工作的人。
It’s a good place for a camp. 那是个露营的好地方。
She bought some clothes for winter. 她买了些冬天穿的衣服。
用法11:(表交换)换,以……作交换。如:

He mistook a rope for a snake. 他把一条绳子误认为是蛇。
He knew that for a fact. 他知道那是事实。
The missing persons were given up for dead. 大家都认为那些失踪的人已死了。
【用法说明】用于此义时,有时相当于as, to be, as being,但要注意不同句型的搭配习惯。如:
I took him for an honest man. / I took him to be honest. 我看他为人老实。
It was built for [as] a pleasure boat. 这船建作游艇之用。
比较:
He took her smile for agreement. 他把她的微笑视为同意。
Will you take me as your partner? 你把我看作你的合伙人好吗?
按传统语法,take…for…通常指误认为是……,而take…as [to be] 则主要指正确地认为是……。但在现代英语中,有时并未完全遵守此规则。
但是与mistake 连用的则通常是for 而不是as。如:
We mistook the house for a hotel. 我们把那房子误以为旅馆。
用法13:(表支持、赞成)支持,赞成。如:
Are you for or against the plan?你是支持还是反对这个计划?
I’m all for the young enjoying themselves. 我完全赞成年轻人多玩玩。
用法14:(表基准)就……来说,以……而言,作为。如:

用法17:(表安排的时间)在,于。如:
The appointment is for 10:30. 约会定在十点半。
We’ve invited our guests for 7 o’clock. 我们已邀请我们的客人7点钟来。
We’ve booked our holiday for the second week in July. 我们的假期安排在七月份的第二个星期。
The next meeting was arranged for the tenth of May. 下次会议已定于5月10日举行。
【用法说明】用于此义时,for 主要指安排或约定的时间,所以像下面两例中的介词at,in 就不能换成for。如:He gets up at six every day. 他每天6点钟起床。
He was born in September, 1988. 他出生于1988年9月。
用法18:(表让步)尽管,虽然。如:

【用法说明】(1) 下面两句同义,但以第一句为普通。如:
老人快跑是危险的。
正:It is dangerous for an old man to run fast.
正:For an old man to run fast is dangerous.
(2) 有时可表目的。如:
I’ve sent my coat away for i t to be cleaned. 我把外衣送去洗了。
For sales to increase, we must lower our prices. 为了增加销量,我们必须降低价格。fetch最佳用法
(3) 有时用于than 后引出不定式的逻辑主语。如:
