Tense的問題

當咱們表達在未來的一段特定的時間內將會完成的事時，就會用上 Future Perfect Tense。
E.g.：You can borrow the book next Monday. I'll have finished it by then.
E.g.：You can come to my office tomorrow. I'll have been back to Hong Kong tonight.
E.g.：Don't worry, I'll have finished the homework by the end of tonight.
E.g.：The dinner will have been ready by the time you return to home tonight.

心水清的一定會發現每一句都會有一個 by 字，這個 by 是用來界定一個特定的時間。不過除了用 by 之外，當然還可以以其他字來界定時間。
