第三篇
Preserve the Environment
Throughout history man has changed his physical environment in order to improve his way of life.
With the tools of technology he has altered many physical features of the earth.He has transformed
woodlands into farmland,and made lakes and reservoirs out of rivers for irrigation purposes or hydroelectric
power. Man has also modified the face of the earth by draining marshes and cutting through mountains to
build roads and railways.
However,man's changes to the physical environment have not always had beneficial results.Today,
pollution of the air and water is an increasing danger to the health of the planet.Each day thousands of tons
of gases come out of the exhausts of motor vehicles;smoke from factories pollutes the air of industrialized areas
and the surrounding areas of countryside.The air in cities is becoming increasingly unhealthy.
The pollution of water is equally harmful.In the sea,pollution from oil is increasing and is killing enor-
mous numbers of algae（水藻）,fish and birds.The whole ecological balance of the sea is being changed.
The same problem exists in rivers.Industrial wastes have already made many rivers lifeless.
Conservationists believe that it is now necessary for man to limit the growth of technology in order to sur-
vive on earth.
The purpose of the writer is___________.
A.to reduce modern technology
B.to improve man's way of life
C.to warn people not to change the natural environment
D.to call attention to the protection of the natural environment

第三篇
Acceptance of Chronic Illness
Holding on to hope may not make patients happier as they deal with chronic illnesses or diseases.
accorcting to a new study by University of Michigan Health System researchers.
"Hope is an important part of happiness,"said Peter
A. Ubel, M.
D. director of the U-M Center for
Behavioral and Decision Sciences in Medicine and one of the authors of the happily hopeless study,"but
there's a dark side of hope.Sometimes,if hope makes people put off getting on with their life,it can get in the
way of happiness."
The results showed that people do not adapt well to situations if they are believed to be short-term.Ubel
and his co-authors一both from U-M and Carnegie Mellon University一studied patients who had new
colostomies:their colons were removed and they had to have bowel movements in a pouch that lay outside
their body.
At the time they received their colostomy,some patients were told that the colostomy was reversible一that
they would undergo a second operation to reconnect their bowels after several months.Others were told that the
colostomy was permanent and that they would never have normal bowel function again.The second group一the
one without hope一reported being happier over the next six months than those with reversible colostomies.
"We think they were happier because they got on with their life.They realized the cards they were dealt,
and recognized that they had no choice but to play with those cards,"said Ubel,who is also a professor in the
Department of Internal Medicine.
"The other group was waiting for their colostomy to be reversed,"he added."They contrasted their current
life with the life they hoped to lead,and didn't make the best of their current situation."
"Hopeful messages may not be in the best interests of the patient and may interfere with the patient's
emotional adaptation,"Ubel said."I don't think we should take hope away.But I think we have to be careful
about building up people's hope so much that they put off living their life."
What could be the message of the passage?
A.Giving up hope means giving up happiness.
B.Letting go of hope is at times a better choice.
C.Hope is what makes people move on.
D.Hope frequently gets in the way of happiness.
