The Mind-Body Connections
Norman Cousins was a famous American magazine editor. In 1964,he returned from an overseas trip
and then became very ill.In the hospital,he had a terrible pain and couldn't move his body.Doctors told
him he had a serious disease called ankylosing spondylitis（强直性脊柱炎）and said he had only 1 chance in
500 of surviving. They gave him powerful drugs,but his condition only got worse.
Cousins had read about a theory that negative emotions can harm your health.He believed that positive
emotions were good for one's health,and he decided to try an experiment.He would fill his days with good
feelings and laughter and see if that might improve his condition.
He left the hospital and moved into a hotel room.There,he got a large supply of funny TV programs and
copies of old Marx Brothers movies and cartoons.He also hired a nurse to read funny stories to him.His plan
was to spend the whole day laughing and thinking about happy things.On his first night in the hotel,Cousins
found that laughing at the movies helped his body produce chemicals that reduced pain.For the first time in
weeks,he could sleep comfortably for a few hours.Every time the pain came back,he watched another
funny movie and laughed until he felt better.
Over time,Cousins was able to measure changes in his body with blood tests.He found that the harmful
chemicals in his body decreased at least 5 percent every time he watched a funny movie.After a short time,
he was able to stop taking all of his medications.Finally his condition improved so much that he could go
back to work.
Cousins later wrote a book about how laughter and happiness helped him to survive a deadly illness.
Many people didn't believe his story and said that his doctors were wrong about his disease.But since then,
research has found that emotions do have a strong effect on physical health,and experiments found that
laughter can help to reduce pain.Scientists today are working to understand the ways that our minds affect
our bodies.
When Cousins wrote his book,everyone agreed with him.
A.Right
B.Wrong
C.Not mentioned

[单项选择] What our society suffers from most today is the absence of consensus about what the society and life in it ought to be. Such consensus cannot be gained from society’’s present stage, or from fantasies about what it ought to be. For that the present is too close and too diversified, and the future too uncertain, to make believable claims about it. A consensus in the present hence can be achieved only through a shared understanding of the past, as Homer’’s epics informed those who lived centuries later what it meant to be Greek, and by what images and ideals they were to live their lives and organize their societies.
Most societies derive consensus from a long history, a language all their own, a common religion, common ancestry. The myths by which they live are based on all of these. But the United States is a country of immigrants, coming from a great variety of nations. Lately, it has been emphasized that an asocial (不合群的) narcissistic (自我陶醉的) personality has become characteris
