[单项选择]To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain. Its first use was as a shade against the sun.

[单项选择]Passage One
The cultural values of a society determine the social norms of the society. The SOCIAL NORMS are the group-shared rules of behavior. These norms are the expected ways of behaving in the society based on the shared values--the purposes and goals--of that society. For example, because we place some value on physical modesty, we have the social norm of wearing clothes in public. To be an accepted member of society, one must live by the rules which that society imposes. When an individual does not behave according to these norms, that person is considered a deviant. A person who walks down the main street of an American city with no clothes on is regarded as a deviant, that is, a person who does not follow the standard rules of behavior.
Some norms apply to all persons in a particular situation. For example, in our culture all persons are expected to be quiet in a library; obey the traffic signals; eat with a knife, fork and spoon; stand during
A. Being quiet in church.
