標題[考題] 時態與助動詞用法
時間Mon May 31 23:16:40 2010
考題：多益
題目：
1.By the time he____ at the office, everybody_____.
a. arrives, has left
b. arrived, had left
2.I haven't received the letter yet. It might____to the wrong address.
a. have been sent
b. be sent
3.Mary____be hungry, because she just had lunch.
a. couldn't
b. can't
答案：
1.b
2.a
3.b
提問：
1.第一題的兩組答案時間軸的配置似乎沒有問題，那為何不能選a的現在式呢？
2.第二題，信先送出，沒收到信的動作在後用完成式，那送信不是應該用現在式嗎？
為何答案是a的完成式？
3.can 跟 could 在表達"能力"時可以互用，請問為什麼不能用a的couldn't?
謝謝
