From this point of view, America is very much like a salad bowl where individual ethnic groups blend together, yet maintain their cultural uniqueness. They may work together during the day at similar jobs and in identical companies, but at night they may return to their ethnic communities where the flavor of their individual culture dominates their way of life. This is why perhaps there is so much diversity within America. Each ethnic group has its own special interests, language, food, customs and traditions to protect and defend. This idea of the salad bowl is referred to by sociologists as cultural pluralism. It simply means that American society is a collection of many cultures living side by side within one country.
The other concept which is also used to describe American society is that of the melting pot. In this usage, society is like a pot of stew (炖菜) or a cauldron (大锅) of porridge. All of the ingredients mix and blend together losing their identity and yield a bit of what they were to become a new reality. A pot of stew is very different from a bowl of salad. Within the stew, the meat and vegetables in the cooking process give to each other a bit of their own flavor. The longer the stew is allowed to simmer (炖), 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. Whether a salad bowl or a melting pot, America can best be described as a mixture of both; that is to say, a nation where there is unity in diversity.
Why does someone see America as a salad bowl?
A.The Americans work together during the day and night.
B.Each ethnic group has its unique culture.
C.There is no culture diversity in America.
D.America society is a unity with one culture.
