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)
