點用 Should,ought to, have to, must 來問問題 (詳解) (急)

should /ought to都係應該的意思

例如, you should study hard, 你應該努力讀書
doctors ought to save lives, 醫生應該救人

have to, must都係一定的意思

例如, i have to do my homework, 我一定做功課
i must do my homework, 我一定做功課(有一個恆常的意思)

要用這些字來問問題, 可以這樣:
where should i go?, 我應該去邊度
you should go to.........., 你應該去......

should同ought to都係應該的意c
have to do something應該去做某些事.
must- 一定的意c:)
考試加油^^
