新視野大學(xué)英語視聽說教程第三冊 Unit 1 MODEL2 I can’t think of it off the top of my head.

John: Hey, Sue. Do you know what Jack’s home phone number is?
Susan: I can’t think of it off the top of my head. I don’t have my address book on me, and I don’t have my mobile phone with me, either.
John: That’s too bad! I’ve got to find him now. It’s urgent! If I can’t find him today, I’ll be dead!
Susan: You might want to look it up in the phone book.
John: I’ve checked already, but it seems that hid phone number is unlisted.
Susan: Maybe it’s under his roommate’s name.
John: Well, I guess so.
Susan: Well, why don’t you call Jane? She has his phone number.
John: I’ve tried, but no one answered!
Susan: Maybe call his office and ask his secretary.
John: I’ve already tried. She won’t tell me. She says it’s private.
Susan: Oh, that’s right. They usually don’t release private information over the phone.
John: It’s a pity. You usually have a powerful memory, but you can’t help today. What’s wrong with you? Your memory seems to be fading early.
Susan: It’s not my memory is fading. I do have memory for face and names, but a poor one for number and dates
