1.學習21課的對話，可以復習日常交際用語中“打電話”的常用語。
電話鈴響了，接電話的人通常先報自己的姓名或自己的電話號碼，如：Hello, this is Tom speaking. 或 Hello, Tom 或Hello, 8433156.
如果對方找的就是Tom，則會馬上說出自己是誰，如：Hello, this is Mary speaking 或 This is Mary. 或It’s Mary here .接著就講所要談的事情。如果對方找的不是Tom，而是Peter，對方可能詢問：Is Peter in ?或 Is Peter there ? 或 Is Peter at home ?或者提出要同Peter通話的要求，如：May/Can/Could I speak to Peter ,please? 或 I’d like to speak to Peter, please.
如果Peter在家，你要去叫Peter來接電話，你要對方稍等一會，通常說：A moment, please. 或Hold on, please.
如果Peter不在，你可以告訴對方，并請他留下口信。你可以說：Sorry, Peter isn’t in ./ Peter is out. / Peter isn’t here right now. Can/Could I take a message for you ? 或 Would you like to leave a message ? 或者叫他晚些時候再打電話，并告訴他Peter可能回來的時間。
如：Can you call later? He’ll be back at about…… 例如：
A: Hello, this is Charlie Green 喂，我是查理格林。
B: Hello, it’s Jack here, Could I speak to Peter, please? 喂，我是杰克。請彼得接電話好嗎？
A: Sorry, he isn’t here right now .Can I take a message for you? 對不起，他現在不在,要我給你帶個口信給他嗎?
B: Yes, please tell him I’ll go and see him this evening. 好的, 請告訴他我今天晚上要去看他。
A: Sure, I will。 Anything else? 我一定轉告，還有什么事嗎？
B: No, Good-bye! 沒有，再見！
A: Good-bye!再見！
2. Excuse me for ringing you so late in the evening.對不起，晚上這么晚了我不給你打電話。
That’s OK.沒關系。
“Excuse me”是表示歉意的交際用語。后接介詞短語for……，表示失禮的原因。回答時通常用That’s OK（沒關系。） That’s all right .沒什么。）Never mind.（不要緊。）例如：
A: Excuse me for ringing you so early in the morning.對不起，早上這么早給你打電話。
B: That’s OK.沒關系。
3.You had it when I last saw you. 我上次見到你時，看到你有雞年的郵票。

你哥哥最近一次給你寫信是什么時候？
I last saw him two months ago.
我上次見到他是兩個月前。
4.Oh! What a pity! / What a shame! 噯！太遺憾了！
這兩個句子都是表示遺憾的交際用語，a shame(=a pity)作“遺憾的事”解。例如：

這是由形式主語it引導的表示遺憾的用語，即由It is a pity +that clause（從句）構成，由that 引導的主語從句表示遺憾的具體內容，連詞that常可省略。又如：
It’s a pity (that) he cannot join us in the travel 很遺憾，他不能參加我們的旅行了。
