C

Sometimes we cry because we are sad and sometimes because we are extremely happy.An irritant(刺激物),such as onion(洋葱) smell or grains of sand in the eye,can also make cry.In this case tears perform an obvious role in getting rid of substances that might harm the surface of the eye.

Dr.William Frey of the Dry Eye and Tear Research Center at St.Paul in Minnesota,USA,believes that tears from emotional causes may perform a similar role.He thinks that crying could get rid of emotional stress by washing away a chemical in the blood caused by strong emotions. To prove his theory, he hopes first to identify this chemical and then see if it is found in tears of sadness or happiness.  

So far, Dr.Frey has failed to find out the difference between emotional tears and tears caused by an irritant in the eye.This may be because these substances themselves cause a degree of stress and emotion.What he has identified in all tears is a variety of biochemicals(生化物)which are one of the causes of stress.A more detailed study may help us understand why sufferers from stress-related disorders cry less often than healthy people.Dr.Frey is also very interested to see if there are any physiological(生理学的)explanations for why women,in general,cry five times more often than men,on average.

A. show that there are two types of tears,caused by irritants and by emotions
