  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

  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。

  词汇学习 Word study

  1.risk

  (1)n. 危险,风险:

  Is there much risk of losing money in doing football pools?买足球新概念很有输钱的风险吗?

  Roy Trenton took/ ran the risk of damaging his bus and drove it into the back of the thieves' car.罗伊·特雷顿冒着撞坏他开的那辆公共汽车的危险把它撞在了小偷们的车的后尾上。

  John saved me at the risk of his own life.约翰冒着生命危险救了我。

  (2)vt. 冒……危险,使……遭受危险:

  We'd better take a taxi. We can't risk missing the plane.我们最好还是坐出租车。我们不能冒误飞机的危险。

  John risked his own life to save me.约翰冒着生命危险救了我。

  2.run与catch

  动词run的本意是"跑",后面加上不同的小品词可以表达"追赶"、"逃跑"等多种含义:

  She ran through the forest after two men.她穿过森林,追赶两个男人。

  The man ran away with her bag.那人拿了她的包跑了。

  She has run off with all his money.她拐带着他所有的钱逃走了。

  The men dropped the bag and ran away.他们扔下提包逃跑了。

  catch的主要意思是"抓住"、"捉住"、"逮住",但有些时候它可以表示"(及时)赶上"、"追上"等:

  He ran quickly to catch the last bus home.为了赶上最后一班回家的公共汽车他快速地跑着。

  When she caught up with them, she saw that they were going through the contents of the bag.当她赶上他们时,发现他们正翻着包里的东西。
