语法 Grammar in use
动名词(2)
在第20课的语法中，我们学习了动名词的形式和一般作用，知道它可以代替名词作句子的主语、宾语、介词宾语等，也学习了它的否定式和完成式：
Washing the car made me tired.
擦洗汽车使我很累。(主语)
I enjoy reading.
我喜爱读书。(宾语)
Before leaving the office, he gave me a book.
他离开办公室之前给了我一本书。(介词宾语)
(1)动名词还可以用于动词+介词之后：
We are looking forward to his coming.
我们盼望着他的到来。
(2)在start，begin， continue等后面，既可以用不定式又可以用动名词，区别不大：
I began to learn/ learning English two years ago.
我两年前开始学英语。
(3)在love，like，prefer等动词后面，用不定式和动名词意义有所区别。带不定式时常表示特定的未来的事件(如正准备做某事或建议做某事)，带动名词形式时则表示目前正在进行中的活动或一般的行为。在prefer…to…结构中则只能用动名词:
I'd like to watch TV.
我(现在)想看电视。(特定)
I like watching TV.
我喜欢看电视。(一般行为)
(4)在need，want之后，动名词形式具有被动的含义，相当于被动的不定式：
The windows need cleaning.
这些窗子该擦了。(=need to be cleaned)
His shirt needs washing.
他的衬衣该洗了。
