Some people describe American society as a salad bowl while others think of it as a melting pot.
In a bowl of salad，all the ingredients are mixed together. 1 Together，however，the ingredients make up a unity.All the ingredients of a salad contribute to the finished product.They may be covered with the same dressing(调味酱)，but the green vegetables，tomatoes and cooked corn can all be seen for what they are.
