2、cle.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。女口：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

4、oes 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

5、打广告；advertisefor 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 ， 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。女口：Knives are used for cutting things.小刀是用来切东西的。Thi
