Latest data shows an estimated 39.5 million people around the world are living with HIV, the virus that causes AIDS. According to the report, this means every eight seconds somebody in the world is infected with HIV, resulting in 11,000 people becoming newly infected every day.
The director of UNAIDS, Peter Piot, says most of the new infections, nearly two-thirds, are in Sub-Saharan Africa. But, the biggest increases are in Eastern Europe and Central Asia, where infection rates have risen by more than 50 percent since 2004. He says 2.9 million people died from AIDS-related illnesses this year, the highest number ever.
UNAIDS senior epidemiologist(流行病學家), Karen Stanecki, says infections are rising in countries where HIV prevention programs have not adapted to the changing nature of the epidemics(流行病).  Stanecki noted,"In Thailand, one of our past success stories, a large percentage of new HIV infections are occurring in people considered to be low risk. One third of new infections are among married women."
It says data shows increased use of condoms has resulted in drops in HIV prevalence(流行) among young people between 2000 and 2005 in a number of African countries, including Botswana, Kenya and Zimbabwe. Nevertheless, the report notes young people between the ages of 15 and 24 account for 40 percent of new HIV infections. It finds the risk behavior, such as injecting drug use, homosexuals, is a factor of concern in many regions of the world, especially in Asia, Eastern Europe and Latin America.
The report notes the emergence (出現(xiàn)) of injecting drug use as a factor of HIV in Kenya, Tanzania, Nigeria and South Africa is a recent development in Sub-Saharan Africa.
51. According to the news report, how many people are newly infected with HIV a year?
A. 39.5 million.            B. 2.9 million.             C. 3.5 million.              D. 4 million.
52.   The highest rate of new HIV infection is in ________.
A. Sub-Saharan Africa                                      B. Eastern Europe

Scientists have developed a water treatment system that they say is a powerful but simple way to save lives. Four grams of chemicals can treat ten liters of dirty water for a low cost, about ten cents.
Experts say infections from dirty water kill several thousand children in developing countries every day. The Procter and Gamble company has been developing the "PUR Purifier of Water" system since 1995. The company has been working with the United States Centers for Disease control and Prevention(C.D.C.).
C.D.C. researchers tested it in Guatemala, Pakistan and Kenya. Procter and Gamble researcher Greg Allgood says cases of diarrhea(腹瀉) in those studies fell by about 50 percent. Researchers from Johns Hopkins University in Maryland tested the system at a refugee camp in Liberia. Mr. Allgood says that study found a reduction of more than 90 percent. Use of the system is being expanded worldwide.
The treatment contains bleach(漂白劑) to kill disease-causing organisms. It also contains something that dirt and other particles stick to. Mr. Allgood says the chemicals can remove lead and other dangerous metals and even agricultural poisons like D.D.T.
Mr. Allgood heads the Children's Safe Drinking Water program at Procter and Gamble. He says about forty million packets of the treatment have been given to countries for free. They have been used in emergencies and in areas with limited supplies of clean water.
Clean water is a limited resource in many parts of the world. Delegates from about 130 nations attended the Fourth World Water Forum last month in Mexico City. Scientists, policy experts and others discussed ways to provide clean water to the world’s poor. Organizers say more than twenty percent of the world population lacks clean drinking water. The final declaration did not go so far as to declare water a human right. But it did say that governments, not private companies, must take the lead in improving the public’s ability to have clean water.

Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday.
They found that when people listened to their favorite music, their blood vessels (血管) dilated in much the same way as when they are laughing, or taking blood medications.
"We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology (心臟病學) at the University of Maryland Medical Center in Baltimore.
"Blood vessel diameter improved," he said. "The vessel opened up pretty significantly. You can see the vessels opening up with other activities such as exercise." A similar effect is seen with drugs such as statins.
When blood vessels open up more, blood flows more smoothly and is less likely to form the clots (凝塊) that cause heart attacks and strokes. "We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health," said Miller, who presented his findings to a meeting of the American Heart Association in New Orleans.
Miller's team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music. They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function.
Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music. Listening to music they disliked — in most cases in this group heavy metal — blood vessels narrowed by six percent, Miller said.
Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly. "I asked myself what other things make us feel really good, besides calories from dark chocolate of course. Music came to mind. ... It makes me feel really good," he said.
Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual.
1. The underlined word dilate (in paragraph 2) is closest in meaning to “_____”.
A. widen             B. move               C. change              D. increase    
2. According to the passage, which of the following will NOT cause blood vessels to open up?
A. Taking exercise.                            B. Listening to unpleasant music.
C. Bursting into laughter.                       D. Taking drugs like statins.
3. It can be inferred from the passage that _____.
A. blood clots are caused by heart attacks and strokes
B. music is better than chocolate for your health
C. the style of music has different effects on different people
D. a person’s overall health is more influenced by how much exercise he gets

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk.
Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma (黑素瘤).They said that they found faults in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence (發(fā)生率) faster than any other cancer in the United States.
But questions has been raised about sunscreen and whether it may has opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--- people with fair skin and freckles (雀斑), for example--- are more likely to use sunscreen.As a result, it may appear that sunscreen users get cancer more often.
The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.
小題1:People with fair skin and freckles         .
A.seldom use sunscreen
B.a(chǎn)re more in danger of skin cancer
C.can be free from the harm of the sun
D.often expose themselves to the sun
小題2:We can learn from the passage that         .
A.sunscreen users get skin cancer more often
B.the volunteers have proved the effect of sunscreen
C.the new study was based on the experiences of volunteers
D.the number of skin cancer patients is increasing in America
小題3:Which of the following can be the best title for this passage?
A.Sunscreen to Prevent Skin Cancer
B.Sunscreen to Increase Skin Cancer
C.Skin Cancer Caused by Sunscreen
D.Skin Cancer Caused by Freckles

All of my childhood and early, adult life, my mom weighed over 220 pounds (one pound =" 0.454" kilograms). I could feel the pain that my mom experienced with her fatness.
I was never uncomfortable about my mother, but I think she was uncomfortable about herself, and that feeling was painful for all of us. And she began to lose weight.
After more than twenty years of battling obesity(肥胖), my mother completed a forceful eighteen-month diet that left her ninety pounds lighter than before. A new woman was born! At age twenty-eight, I got a new mom! For the first time, I met the woman my mother truly was, the beautiful little lady under the fatness. It wasn’t so much her new body that was the surprise, but rather her new spirit.
To celebrate her new size and to devote herself to dancing again, my mother joined a “Mrs. Forty-Plus” competition, where she would have to model, give a speech and provide a dance performance. She told our family that she did not care if she won — she simply had always wanted to perform on stage.
She told each one of us, “I’m not doing it to win; I’m doing it to dance!”
The competition was exciting! I prayed that my mom would win, but while watching her on stage I was simply overjoyed just by her effort. To me, she had already won. She posed to perfection, her speech brought tears to everyone’s eyes, and her performance was wonderful.

TEENAGERS lead an exciting life in high school, making friends and dreaming about the future. However, as all young people know, teenagers have plenty of worries too.
Do you know what British teenagers worry about most? A survey by the UK's Department of Health shows that the top worries are losing weight (減肥) and fitting in (適應). Over 100,000 teenagers took part in the research.
Losing weight is a big concern among teenagers. This may be an effect of famous people with perfect bodies around them.
Adolescence is a physically and emotionally difficult time. Teenagers want to feel good about their bodies.

Over 2,000 years, the examination of the pulse has been a mysterious skill in Traditional Chinese Medicine. Although many westerners may have known something about methods like inspecting, listening and enquiring, pulse reading as a tool to determine physical condition is not common knowledge. It is therefore worth our effort to take a closer look at it.
There are three positions on each wrist which are used for analysis: the front, middle and back part, and analyzed at three different levels: superficial, middle and deep.
On the left wrist, the front position focuses on the condition of the heart and small intestine (小腸), the middle position concentrates on the functions of the liver and gall bladder, and the back position is connected with the kidney. The lungs and large intestine are the centre of attention in the front position on the right wrist, with the middle position focusing on the spleen and stomach and the back taking note of the “Gate of Vitality Fire’. This is the heat provider for all bodily functions.
In regards to the various levels, the superficial level reflects the state of energy, the middle level shows the state of blood flow, and the deep level is an indication of the state of the Yin organs. Suppose that the pulse in the left middle position was soft and smooth, neither superficial nor deep, it would suggest that the liver and gall bladder are in a good state of health.
Checking the pulse is actually far more complex. Doctors need to be able to recognize 26 different pulse categories. For example, a scattered pulse which is irregular and hardly noticeable, is a sign that a patient is critically ill and nearing death. Other categories include the rapid pulse, probably a sign of a fever; or the tense pulse, which may suggest that the patient is suffering from pain. Many pulses only have subtle differences; thus, pulse examination is often seen as being more than just a skill but an actual art form.
This kind of medical diagnosis can be affected by many factors, so before any examination, it is important that patients are in a relaxed physical and mental state so they can get the most accurate reading. The morning is often the best time to take such a reading, as a busy day in the office or vigorous exercise before seeing the doctor can influence the quality of the pulse. The right amount of pressure must be applied by the doctor for the right duration of time. Patients’ characteristics are also of importance. Children, for instance, have quick pulses and athletes have slower than usual ones. Even seasonal influences need to be taken into account.
59. Which of the following is the most suitable title for this passage?
A. Chinese Pulse Checking      B. Difficulties in Pulse Checking
C. What Makes a Good Doctor   D. Brief Introduction to Traditional Chinese Medicine
60. Which factor is NOT mentioned as possibly influencing the accuracy of a pulse reading?
A. Amount of force used.                         B. Time of day.     
C. Climate.                                          D. Body height.
61. From the passage we can infer that the writer believes __________.
A. Chinese medicine is too difficult to learn
B. pulse reading requires a long-time study and practice
C. doctors need to be familiar with Chinese history
D. pulse examination is unimportant and no longer necessary

At one time or another most farmers have problems with mice. This is especially true for grain farmers. Mice eat a lot of grain. They also carry diseases(疾病), which people can get from eating or touching grain the mice have made dirty. Farmers can use special grain storage building or they can kill the mice. However, both methods can be costly. Farmers must buy materials to build the special grain storage buildings or chemical poisons to kill the mice.
