题目内容

Mr Black decided to give up his farm and devote all his time to______ those children living on the streets.


  1. A.
    help
  2. B.
    helping
  3. C.
    be helping
  4. D.
    being helped
B
试题分析:考查动名词用法。本题的固定词组devote one’s time to sth/doing sth致力于做某事;句意:布莱克先生决定放弃他的农场,把所有的时间都花在了帮助那些生活在街上的孩子们身上。句中的to是介词,后面接动名词的形式。故B正确。
考点:考查动名词的用法
点评:本题中的动名词helping是放在介词的后面,做介词的宾语。动名词在英语中还可以做主语,表示经常性习惯性的行为,要区别与不定式做主语,不定式做主语表示一次性具体的行为。
