托福语法之条件现在时

发布时间:2017-01-05来源:留学网

  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:

  我希望我会成功。

  I hoped(that) I would/should succeed.

  我曾希望我会成功。
