   1. 不定式的否定式的构成


  通常是将否定词not或never置于不定式之前,即构成not to do 或never to do 的形式,注意not和never一定要放在不定式符号to的前面,而不是其后面。如:
  The doctor advised me not to smoke. 医生劝我不要抽烟。
  Father warned me never to drive after drinking. 父亲警告我不要酒后开车。
  【注】若不定式为完成式和被动式,否定词应置于整个结构之前。如:
  She pretended not to have seen him. 她假装没看见他。
  It is nice not to be dependent 1 on others. 不依靠别人是好的。
  2. so as to do sth 和in order to do sth 的否定式
  对于这两个结构的否定式,通常是将否定词置于不定式符号to之前,而不是置于整个结构之前或其他位置。如:
  Study hard so as not to fail the exam. 努力学习,以免考试不及格。
  He came in quietlyin order not to wake his wife. 他轻轻进来,以免把他妻子吵醒。

adj.依靠的,依赖的,依赖他人生活者
  • He has a mother completely dependent on him.他有一个完全靠他赡养的母亲。
  • The country is dependent on foreign aid.这个国家靠外援生存。
