2、what were here for.这正是我们来的目的。Whats 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
3、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
4、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
5、 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为寻找某物而打广告。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,“
6、为某人的死报仇”,说成英语是 avenge sbs death,而不是 avenge for sbs 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。Its 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 fo
7、r 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:Thats 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
8、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 couldnt speak for laughing.我笑得说不出话来。He couldnt 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
9、: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 dont know if Ill have time to go out.有这么多

11、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
12、.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 tr
13、ain 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:Im going away for a few days.我要走开几天。Ive 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。【

15、eading 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。Its a good place for a camp.那是个露营的好地方。She bough

17、ook 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 s
18、mile 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,takefor 通常指误认为是,而 takeas 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?Im all for
19、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:Hes done well for a beginner.作为新手,他干得很好。He is heavy for a small boy.作为一个小男孩而言,他的身体算重的了。She was short for her age.就她的年龄来说,个子是矮了点。The day is cool for July.在 7 月里这样的日子算是凉快的了。用法 15:(表比例)每就。如:Plant three trees for every one that is cut dow

22、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:For all his money,hes a very lonely man.他虽然富有,可是非常
23、寂寞。For all his efforts,he didnt succeed.尽管他做了很多努力,却仍然没有成功。I love you,for all your shortcomings.尽管你有很多缺点,但我仍然爱你。【用法说明】用于此义时,通常与 all 连用。(见上例)用法 19:(与不定式连用引出逻辑上的主语)。如:It is for you to decide.该由你来决定。All I want is for us to be together.我希望的只是我们能在一起。Is there any need for me to go?我有没有必要去?He spoke too fast

26、of 与 for 是三个极易混用的介词,同学们在具体使用时应从以下三个方面来掌握:一、表示“的”含义时,应根据不同的关系选用不同的介词.1.若表示“所有,所属”关系时,用介词 of.如:the life of the people 人民的生活 the roof of the house 屋顶 2.若表示“解释,说明”关系时,用介词 for.如:the money for the shoes 鞋钱 the shop for clothes 成衣店 3.若表示“解答,用途”关系时,用介词 to.如:the key to the exercise 练习的答案 the way to the hospi
27、tal(到)医院的路 二、在含双宾语的句子中,当间接宾语(指人的宾语)置于直接宾语(指物的宾语)之后时,间接宾语之前须加上介词 to 或 for.1.当及物动词是 give,pass,tell,teach,ask,show 等必须有双宾语意义才完整的句子中,若将间接宾语放在直接宾语之后,用介词 to 连接.如:Miss Cao teaches English to us 曹老师教我们英语.Please pass a cup of tea to me 请给我一杯茶.2.当及物动词是 m。ake,buy,fetch,get,play,find 等只需一个宾语就能表达一个完整意义的句子中,若将间接宾

29、oolish,polite,honest 等.如:It is very kind of you to say so 你这样讲真是太好了.Its very clever of him to answer the question 对他而言回答这个问题真是很聪明.若这个形容词是描写事物性质,而不是对逻辑主语的品格进行评价时 用 介 词for引 导.可 用 于 该 句 型 的 形 容 词有:difficult,easy,hard,important,necessary,impossible 等.如:It is not difficult for us to learn English well 对我
