C

Sometimes we cry because we are sad and sometimes because we are extremely happy．An irritant(刺激物)，such as onion(洋蔥) 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(生理學(xué)的)explanations for why women，in general，cry five times more often than men，on average．

64. The main purpose of Dr．Frey’s study of tears is to           

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

    B. find out the cause of stress-related problems and emotional disorders

       C. explain why women cry more often than men

       D. prove that tears can remove a chemical in the blood caused by strong emotions

65. Which of the following is true according to the passage?

       A. Tears fail to help get rid of emotional stress．

       B. Irritants in the eye result in tears without causing stress and emotion．   

       C. Healthy people cry more often than those with stress-related problems．

       D. The biochemical identified by Dr．Frey has nothing to do with stress．

66. We can learn from the passage that __________．

       A. crying does us more harm than good

       B. inner feelings don’t affect our bodies

       C. sorrow may cause some chemicals in our blood

       D. emotional tears are different from tears caused by irritants in the eye

67. Dr．Frey believes that tears from emotional causes may play a role in getting rid of ______．

       A. emotional stress by washing away a chemical in the blood

       B. onion smell or grains of sand

       C. sufferings from irritants

       D. substances that might not harm the surface of the eye

Perhaps the most famous theory, the study of body movement, was suggested by Professor Ray Birdwhistell. He believes that physical appearance is often culturally programmed. In other words, we learn our looks—we are not born with them. A baby has generally informed face features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those around-family and friends. This helps explain why the people of some areas of the United States look so much alike, new Englanders or Southerners have certain common face features that cannot be explained by genetics(遺傳學(xué)). The exact shape of the mouth is not set at birth, it is learned after. In fact, the final mouth shape is not formed until well after new teeth are set. For many, this can be well into grown-ups. A husband and wife together for a long time often come to look alike. We learn our looks from those around us. This is perhaps why in a single country area where people smile more than those in other areas. In the United States, for example, the South is the part of the country where the people smile most frequently. In New England they smile less, and in the western part of New York State still less. Many southerners find cities such as New York cold and unfriendly, partly because people on Madison Avenue smile less than people on Peachtree Street in Atlanta. Georgia. People in Atlanta, Georgia. People in largely populated areas also smile and greet each other in public less than people in small towns do.

Ray Birdwhistell believes that physical appearance _______.

A. has little to do with culture    B. has much to do with culture
