其实用法不止四个用法,不过手机有字数*,我就附上四个用法吧,如下:
用法1:(表目的)为了。如:
They went out for a walk. 他们出去散步了。
【用法说明】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。(见下面的有关用法)
用法2:(表利益)为,为了。如:
What can I do for you? 你想要我什么?
【用法说明】(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。
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 proct on TV.
正:They decided to advertise their new proct on TV.
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。
用法4:为得到,为拿到,为取得。如:
He went home for his book. 他回家拿书。
