托福语法技巧:条件现在时

来源:网络发布时间:2008-12-08
条件现在时由would/should+动词原形构成(用于第一人称),或由would+动词原形构成(用于其他人称)。
  肯定式: I would/I’d work/I should work
  you would/you’d work等
  否定式: I would not/wouldn’t work或
  I should not/shouldn’t work
  you would not/wouldn’t work等
  疑问式: would/should I work?
  would you work?等
  否定疑问式: should I not/shouldn’t I work?
  would you not/wouldn’t you work?等
  这种形式用于:
  (a)条件句中。
  (b)would和should的特殊用法中。
  (c)过去将来时。当主句的主要动词是过去时的时候,从句中就必须用 would/should而不用 will/shall:
  I hope(that) I will/shall succeed.
  我希望我会成功。
  I hoped(that) I would/should succeed.
  我曾希望我会成功。
  I know(that) he will be in time.
  我知道他会赶得上的。
  I knew(that) he would be in time.
  我当时知道他会赶得上的。
  He thinks(that) they will give him a visa.
  他想他们会给他签证。
  He thought(that) they would give him a visa.
  他本想他们会给他签证。
  I expect(that)the plane will be diverted.
  我料想飞机会改变航线。
  I expected(that)the plane would be diverted.
