D
Many disease researchers have warned that rising global temperatures could lead to more diseases. for example by allowing tropical diseases to expand their ranges into what are now mild regions. This is a particular fear for the diseases carried by insects such as malariac(疟疾） and
sleeping sickness.
But the reality is more complex, argues Kevin Lafferty. a disease ecologist. He argues that a warming climate could favour some diseases in certain regions while controlling them in others.
Lafferty does not deny that climate change might allow malarial mosquitoes to spread to new areas. However he believes that hotter and drier conditions may also get rid of mosquitoes from areas where they currently exist. If this were the case, he says. there would be little. if any, net
increase (净增长） in the risk of disease.
In addition, many mild regions such as southern Europe or the southern U.S. have good sanitation（卫生设备） and insect control programmes which, Lafferty says, would prevent diseases from becoming common even if climatic conditions were suitable.
Finally, he argues, climate change could wipe many species off the plant. Infectious pathogens（病原体） depend on their hosts for survival so they too may become endangered-especially if they,like malaria, rely on more than one host.
But Mercedes Pascual of the University of Michigan points out that there are large human populations in the east African highlands, just outside of the existing range of malarial mosquitoes.She said as temperatures rise, the mosquitoes will reach these areas. So the disadvantages will
outweigh the advantages of decreased risk elsewhere.
Most of the ecologists do, however, seem to agree on one point: predicting where a disease is going to go next involves far more than just considering climate. No matter what the results of the debate are, they all agree that health concerns should continue to play a critical role in climate policy and the debate shouldn't be regarded as weakening the case for action against global warming.
53. According to Kevin Lafferty, climate change__________
A. will not increase the spread of insect-bome diseases
B. may not significantly increase the risk of disease in the whole world
C. will not affect the dry regions where sanitation is good
D. may not affect viruses that depend on more than one host
54. What does Mercedes Pascual think of Lafferty 's conclusion?
A. She disagrees with it. B. She supports it.
C. She is not sure ofit. D. She thinks it needs proving.
55. We may infer from the passage that ___________
A. climate is the only factor in the predictior of the spread of diseases
B. when making a climate policy one should take health into account
C. the debate mentioned in the passage furthers the debate on global warming
D. a policy should be made immediately to try to stop climate change
56. We can learn from the passage that ___________
A. all the disease researchers agree that climate change will spread disease
B. nothing can be done to stop the present global warming
C. scientists have found ways to stop the wild spread of disease
D. ecologists have different views on whether the global warming will spread diseases further

Throughout the world, clothing has many uses. It is used to provide protection from the elements. It is also worn to prevent others from seeing specific parts of one's body. However, the parts of the body that must be covered vary widely throughout the world. Some clothing is worn to
provide supernatural protection. Wearing a lucky shirt to take an exam is calling for supernatural assistance.
People in all cultures use clothing and other forms of bodily decoration to communicate status,intentions and other messages. In North America, we dress differently for business and various leisure activities. North American women usually are much more knowledgeable of and concerned
With little difference in messages communicated by clothes than men. At times, this leads to silly mistakes of interpretation（解释） of female intentions on the part of men. Of course. clothing styles also are intended to communicate messages to members of the same gender（性别）．
Long before we are near enouth to talk to someone, their appearance tells their gender, age,economic class. and often even intentions. We begin to recognize the important cultural clues at an early age. The vocabulary of dress that we learn includes not only items of clothing but also
hairstyles, jewelry, and other body decoration. In most cultures, however, the same style of dress communicates different messages depending on the age, gender. and physical appearance of the individual wearing it.
Putting on certain types of clothing can change your behavior and the behavior of others towards you. This can be the case with a doctor's white lab coat, or an army uniform. Most uniforms are clearly symbolic so that they can rapidly and unmistakably communicate status. For instance. the
strange hairstyle and clothing of the English "punks" are essential aspects of their uniforms.
There are many forms of body decoration other than clothes that are used around the world to send messages. These include body and hair paint, and even body deformation. When doctors put braces on teeth, they are actually doing the same thing - deforming or reforming a part of the body
to make it more attractive.

How to improve our life? Many people think that they have to accept whatever life throws at them. They'11 say," my destiny（命运）. I cannot change it."
Of course not! You don't have to suffer needlessly. Your life depends on you, not on any other extemal（外部的） factor.
I know a woman who says she just accepts what life gives her because she has done everything she can to improve it. Guess what her lifestyle is. She wakes up in the morning, goes to work comes back home. relaxes. chats with people, watches TV, and then goes to sleep. Next day, the same
routine cycle follows.
Huh! Is this what she calls "doing her best"'? She believes she has tried her best and just accepts for her heart that this is the life that has been intended for her. and that her luck can only change if God wills it. She hasn't realized that we have to do our share of making the effort to live the life of our dreams.
Remember that you harvest what you sow. You have to get off the sofa, get your eyes off the TV screen, get your hands off the phone (unless it contributes to your success), and get your mind and body to work! Don't expect your luck to change, unless you do something about it. If something
goes wrong, don't just regard it as a temporary setback; instead, learn your lesson, make the most of the situation, and do something to solve the problem. It's not enough to think positively; you also have to act positively.
If someone's life is in trouble, do you just hope and pray that things will turn out fine?Of course not! You get to do anything you can to save the person. So it is with your own life. It is not enough to hope for the best, but you have to do your best. In other words, don't just stand (or sit )there, do something to improve your life .
45. According to the woman mentioned in Para3, her life ________
A. doesn't need improving B. couldn’t be improved
C. will be better some day D. will be worse in the future
46. What does the author think of the woman's life?
A. Passive. B. Positive. C. Colorful. D. Boring.
47. Which of the following statements is the author's opinion?
A. Your temporary problem is not discouraging.
B. Your luck can be changed by your efforts.
C. You can only achieve success when God wills it .
D. You should treat yourself in the way you treat friends.
48. In Para.5, the author emphasized the importance of_______
A. hope for the best B. intention to succeed
C. positive thinking D. positive action

第一节：阅读下列短文,从每题所给的四个选项 (A. B. C 和D)中.选出最佳选项.
A
When it comes to friends, I desire those who will share my happiness, who possess wings of their own and who will fly with me. I seek friends whose qualities illuminate（照亮） me and train me up for love. It is for these people that I reserve the glowing hours, too good not to share.
When I was in the eighth grade, I had a friend. We were shy and "too serious" about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school. but she would come to my house and we would sit down with pencils and paper. And one of us would say: "Let's start with a train whistle today." We would sit quietly together and write separate poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we, too, were changing into social creatures and the stories and poems
stopped.
When I lived for a time in London, I had a friend. He was in despair(失望） and I was in despair.But our friendship was based on the idea in each of us that we would be sorry later if we did not explore this great city because we had felt bad at the time. We met every Sunday for five weeks and found many excellent things. We walked until our despairs disappeared and then we parted. Wegave London to each other.
For almost four years I have had remarkable friend whose imagination illuminates mine. We write long letters in which we often discover our strangest selves. pach of us appears, sometimes in a funny way. in the other's dreams. She and I agree that,at certain times, we seem to be parts of the same mind. In my most interesting moments. I often think: "Yes, I must tell.. .."We have never met.
It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist, who will only fill up the healing（愈合的） silence necessary to those darkest moments in which I would rather be my own best friend.

Governments and health officials around the world continued to take steps Tuesday against the outbreak of swine flu that has killed scores of people in Mexico and spread to the U.S., Europe and possibly Asia.
By early Tuesday, the swine flu outbreak in Mexico had caused in 152 deaths and more than 1,600 illnesses. So far, at least 113 cases have been proved worldwide, including 64 in the United States; six in Canada; 11 in New Zealand and two each in Spain the United Kingdom and Israel. None has yet resulted in death.
The World Health Organization on Monday raised its alert level from three to four on its six-level scale. The move means the U.N. agency has determined that the virus can transmit
from human to human.
"In this age of global travel, where people move around in airplanes so quickly, there is no region to which this virus could not spread," said Fukuda, assistant director-general of the WHO.
Governments around the world struggled to prevent further outbreak. Some, like China and Russia, banned pork imports from the United States and Mexico. U.S. President Barack Obama said the outbreak was a cause for concern, not for alarm. The government urged travelers to avoid non-essential travel to Mexico.
The latest WHO report listed only seven proved swine flu deaths in Mexico but it was not clear why there was the discrepency.
Mexico City has closed all schools until at least May 6 to help curb(control) the spread of swine flu and ordered 35,00 public venues to close or serve only takeaway meals. In addition, bars, clubs, movie theaters, pool halls, gyms, sport centers and convention halls have been told to close until May 5. Armed police officers are also guarding hospitals in Mexico City while roads and schools in the city of 20 million people are deserted. Officials also have talked about shutting down the bus and subway systems.
57.How many people were found catching swine flu in Spain?
A. 2. B. 11. C. 6. D. 64.
58.When learning the outbreak of swine flu, the WHO was ____.
A. calm B. nervous C. shocked D. careful
59. Fukuda’s words suggest that _____.
A. he likes travel by air
B. global travel hasn’t been affected
C.this virus can spread quickly because of global travel
D. planes must be forbidden to take to prevent swine flu
60.The last paragraph mainly tells us _____.
