J: Hello? Can I speak to Mr. Smith?
A: I'm sorry, but he's out now. May I take a message?
J: Yes. This is John Brown. I'd like to meet him next Monday morning around 10 o'clock.
A: Let me check his schedule... Yes, I think he can see you. But could you call again around five to make sure?

J: 喂？能请史密斯先生听电话吗？
A: 抱歉，他现在不在。要我传话吗？
J: 好的。我是约翰布朗。下星期一早上十点左右我想跟他见个面。
A: 我来查查他的时间表... 可以，我想他可以见你。不过，五点左右你可以再打电话来确定一下吗？

重点解说：

★ He's out now.一语亦可说成He's not in.

★ May I take a message?「要我传话吗？」此语用于来电者所找的人不在时，请教对方需不需要自己代为传话。反之，「我可以留话吗？」英语说成May [Can] I leave a message?。

★ call again「再打电话」cf. I'll call you back.「我会回你电话。」上文的最后一句另有变通的说法，Could I have your number? We'll call you back as soon as [when] he's in.「能告诉我你的号码吗？他一回来我们会立刻回你电话。」

★ make sure ~「确定(某事)」
