[单项选择] Statuses are marvelous human inventions that enable us to get along with one another and to determine where we "fit" in society. As we go about our everyday lives, we mentally attempt to place people in terms of their statuses. For example, we must judge whether the person in the library is a reader or a librarian, whether the telephone caller is a friend or a salesman, whether the unfamiliar person on our property is a thief or a meter reader, and so on.
The statuses we assume often vary with the people we encounter, and change through our life. Most of us can, at very high speed, assume the statuses that various situations require. Much of social interaction consists of identifying and selecting among appropriate statuses and allowing other people to assume their statuses in relation to us. This means that we fit our actions to those of other people based on a constant mental process of appraisal and interpretation. Although some of us find the task more difficult than other

Some People Do Not Taste Salt like Others
Low-salt foods may be harder for some people to like than others, according, to a study by a Penn State College of Agricultural Sciences food scientist. The research indicates that genetic factors influence some of the difference in the levels of salt we like to eat.
Those conclusions are important because recent, well-publicized (大力宣传的) efforts to reduce the salt content in food have left many people struggling to accept food that simply does not taste as good to them as it does to others, pointed out John Hayes, lead investigator on the study.
Diets high in salt can increase the risk of high blood pressure and stroke. That is why public health experts and food companies are working together on ways to help consumers lower salt intake through foods that are enjoyable to eat. This study increases understanding of salt preference and consumption.
