Jack：What are you laughing about?
May:I just saw the serious advertisement on TV for Germen soups.It’s said our products are home-made with the freshest vegetables and fruits.Then a scene in the factory showed that products were prepared and packed by the most sophisticated machinery.
Jack:And I am sure that the word NATURE was put on the jars and cans of the products.I think the stupidest advertisements are those that imply that you are one of a kind.If you buy the product,you will be a very special person.Now you will be just like every other one of the 20 billion people who bought it.
