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 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.

From this point of view，America is very much like a salad bowl where individual ethnic groups mix together，yet maintain their cultural uniqueness. People may work together during the day at similar jobs and in the same companies，but at night they may return to their ethnic groups where their own individual culture directs their way of life. __2__Each ethnic group has its own special customs，language，food and traditions to protect and defend. This idea of the salad bowl is referred to as cultural diversity；that is，American society is a collection of various cultures living together in harmony within one country.

__3__Here，society is like one large pot of soup. All cultural aspects are mixed together，sacrificing their original identity and keeping a bit of what they were to become a new reality. The longer the soup is cooked，the better the taste and the more likely it will be for the mixture to dissolve. In this sense，America can surely be seen as a melting pot where people from all over the world come to live and work together forming one nation. There are dozens of shared symbols. __4__In such a culture，symbols like the flag and the nation's official song serve to break down the walls which separate ethnic groups.

Whether a salad bowl or a melting pot America can be best described as a mixture of both. __5__

A．Both are correct depending on one's point of view.

B．They never lose their shapes，colors or tastes.

C．This is why there is so much diversity within America.
