第五課 助動詞 should 和 must
一.本課要點及示例
在這一課里, 我們要學習的是助動詞 should, s-h-o-u-l-d, should 跟 must, m-u-s-t, must 的用法. 我們也要看看這兩個助動詞的否定式 should not 也就是 shouldn't 和 must not 也就是 mustn't 在意思上跟 don't have to 這個詞組有什么分別.
首先我還是請兩位英文老師給你念一段對話, 請你注意聽英文老師的發 音和聲調.
F: Peter, can you help me for a minute?
M: Yes, what do you want me to do?
F: Will you take the garbage out?
M: Do I have to do it now?
F: Well, you don't have to it now. But don't forget to do it today.
M: All right. I really must go now; otherwise I'll be late for school.
F: You have an exam this morning, don't you? You mustn't be late. Maybe you should ask your father for a ride.
好, 現在我們再把剛才那段對話用慢速度念一遍, 請你注意聽:
F: Peter, can you help me for a minute?
M: Yes, what do you want me to do?
F: Will you take the garbage out?
M: Do I have to do it now?
F: Well, you don't have to. But don't forget to do it today.
M: All right. I really must go now; otherwise I'll be late for school.
F: You have an exam this morning, don't you? You mustn't be late. Maybe you should ask your father for a ride.
在彼得跟他母親的這段對話里, 有幾個句子用了我們今天要學的助動詞 should, must 跟它們的否定式 shouldn't, mustn't 還有 have to 跟 don't have to 這兩個詞組, 現在我請老師把包含了這些詞的句子用慢速度再念 一遍給你聽:
M: Do I have to do it now?
F: You don't have to.
M: I really must go now.
F: You mustn't be late. Maybe you should ask your father for a ride.
