基本的理论区别:
现在完成时强调目前/现在的结果
过去完成时强调过去某动作之前的动作
请看例子吧:
A.
现在完成时的结构:has/have been done,
到目前为止,已被……了
现在完成时的功用与表意: / ,说明/如:
has been finished ,
1.My homework so I can go out to play.(目前/现在的结果是:我可以给你看做完了的作业,或 I go out to play)
haven' t been seen
2. The party will begin,but the students here.(目前的结果是:现场还没有见到学生)
has been learned
3. Because Lesson 3 ,let's do some exercises on it.(目前/现在的结果是:我们知道,了解并理解了相关知识,可以做练习了)
(以上例句有点别扭哈)
B.
过去完成时的结构:had been done
在过去某个动作之前,被……了
过去完成时的功用与表意是:,如:
had been finished,
1.After my homework I out to play.(finish在过去的动作 went out 之前发生,所以,had been finished)
had been beaten
2.The boy ,before I there.(beat 在过去的动作 went there 之前发生,所以,had been beaten)
ed
3.When I arriv ,my room . And it was so tidy.(clean 在过去的动作 arrived 之前,所以就 had been cleaned)
ed
4. Then I realiz my wallet in my room.(leave 在过去的动作 realized 之前发生,所以就 had been left)
