问题     Chemists have been studying why people cry. They say the body produces two kinds of tears. One kind cleans out the eye if it gets dirt in it. But when people cry because of their feelings, these tears have poison chemicals in them. The body is getting rid of chemicals produced by strong feelings.
    In the United States men have heart diseases more often than women do. Doctors say heart disease and some other diseases are related to the pressures of living and working in a modern society. Perhaps men suffer more from these diseases because they do not cry enough. And it is possible that as more and more women work outside the home, they will also suffer from more pressure. Then everyone will need to cry more.
Why do people cry?
选项 A、To get rid of poisonous substances produced by strong feelings.
B、Because they have to work outside their homes.
C、Because they don’t know how to prevent heart diseases.
D、For no reason at all.
答案A
