One day when Jack was walking in the park, he saw a
woman he knew sitting on a bench with a dog beside her.
The dog was looking up at the woman.
  Jack walked up to the woman and said, “Hello, Sue,
how are you? May I sit and talk with you for a while?”
  “Of course, please sit down,” Sue said.
  Jack sat down next to Sue on the bench, and they talked
quietly together.
  The dog continued to look up at Sue, as if waiting to be
fed.
  “That’s a nice dog,” Jack said, pointing at the animal.
  “Yes, he’s handsome. He’s a bit of a mixture, but that’s not
a bad thing. He’s strong and healthy.”
  “And hungry,” Jack said. “He hasn’t taken his eyes off you.
He thinks you’ve got some food for him.”
  “That’s true,” Sue said. “But I haven’t.”
The two friends laughed and then Jack said, “Does your dog bite?”
  “No,” Sue said. “He’s never bitten anyone. He’s always
gentle and good-tempered.”
  Hearing this, Jack decided to pet the dog. He put out his
hand and touched the animal’s head. Immediately it jumped up
and bit him.
  “Hey!” Jack shouted. “You said your dog didn’t bite.”
Sue replied, “That’s not my dog. My dog’s at home.”

             错误的问题
  一天，杰克在公园散步，碰见一位认识的妇女坐在长凳上，旁边还有一
条狗。这条狗一直盯着这个妇女。
  杰克走到妇女面前说：“嗨，苏！最近怎么样？可以和你聊一会儿
吗？”
  “当然，请坐。”苏说。
  杰克在苏旁边坐了下来，他们安静地聊着天。
  那条狗继续望着苏，好像在等着她喂食。
  “真是条讨人喜欢的狗。” 杰克指着那条狗说。
  “是的，它很好看。有一点像混种狗，但也不是件坏事。它很强壮也很
健康。”
  “而且很饿，”杰克说，“它的眼睛从未离开过你，好像等你喂食呢。”
  “是的，”苏说，“但我没有食物。”
  两个人大笑，然后杰克说：“你的狗会咬人吗？”
  “不，” 苏说，“它从来不咬人，总是很温顺，脾气也很好。”
  听到这，杰克想拍一下这条狗。他伸出手抚摸着这条狗的脑袋。狗立刻
跳起来咬他。
  “ 嘿！” 杰克喊，“你不是说你家狗不咬人吗？”
  苏回答道：“那不是我的狗，我的狗在家呢。”
