挂着羊头卖狗肉英语怎么翻？

　　说起挂羊头，卖狗肉又有人照字直译为：

　　“He advertises mutton, but sells dog‘s flesh.”或“He hangs up a sheep’s head at the shop front and sells dog meat.”

　　这两种译法，恐怕老外都难理解，尤其谈到“狗肉”，他们更会反感，因为狗是他们最爱的宠物，不过老外倒有相近的说法：“He applied bait-and-switch tactics in business.（他经商的策略是先引诱顾客来，再改变货物的品质。）”，“Bait-and-switch”当名词用，也可不用连字号“This store uses bait and switch policy.”或者简单的说：“Let the buyer be aware!（让消费者提高警觉）”或“Say one thing and do another.”
