该从何说起呢？可以说出一本书来......

简单地说：
had + 过去分词 = （过去）XXX 了
have/has + 过去分词 = （现在）XXX了
will have +过去分词 = （未来）XXX了

have/has been ...ing = （从过去到现在）一直在XXX
had been ...ing = （从过去某个时间到过去的另一个时间）一直在XXX

看了你的解释比较明白了;)

1）present tense :
I _______ the orphan a number of times since I first met him.(help)这里应该用has been helping还是have helped呢？

2)Nur had sent the parcel yesterday. Nur sent the parcel yesterday.
这两句意思一样吗？

3）The athletes ________ (leave,are leaving) for Canada.
