第五課　助動(dòng)詞 should 和 must
一.本課要點(diǎn)及示例

在這一課里, 我們要學(xué)習(xí)的是助動(dòng)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(gè)助動(dòng)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(gè)詞組有什么分別.

首先我還是請(qǐng)兩位英文老師給你念一段對(duì)話, 請(qǐng)你注意聽(tīng)英文老師的發(fā) 音和聲調(diào).

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(xiàn)在我們?cè)侔褎偛拍嵌螌?duì)話用慢速度念一遍, 請(qǐng)你注意聽(tīng):

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(duì)話里, 有幾個(gè)句子用了我們今天要學(xué)的助動(dòng)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(gè)詞組, 現(xiàn)在我請(qǐng)老師把包含了這些詞的句子用慢速度再念 一遍給你聽(tīng):

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.
