(急急急)請英文高手解英文文法問題

我在讀書。
1) I am studying.
2) I am reading a book.

因版主提到被動語態, 所以不會是不及物動詞的第1句,
我們就以第2句來列出:

現在完成式
主動: I have read a book.
被動: A book has been read by me.

過去完成式
主動: I had read a book.
被動: A book had been read by me.

未來完成式
主動: I shall have read a book.
被動: A book will have been read by me.

現在完成進行式
主動: I have been reading a book.
被動: A book has been being read by me.

過去完成進行式
主動: I had been reading a book.
被動: A book had been being read by me.

未來完成進行式
主動: I shall have been reading a book.
被動: A book will have been being read by me.

以上是單純就文法上列出時態而已, 實際使用上要搭配對照的時間片語或子句才可以, 而且完成進行式的被動語態是幾乎不用的.

不同情景有不同用法,沒有對錯問題!
