  Prevention is a central issue being discussed at the sixteenth International AIDS Conference in Toronto,Canada. Twentyfour thousand delegates are at the conference which ends Friday.

  Bill and Melinda Gates called for faster research to develop preventions like microbicides for women to use when they have sex. The hope is that such products could protect against infection with the virus that causes AIDS.

  Melinda Gates said the way to "change this epidemic" is to put power in the hands of women. In southern Africa,for example,about sixty percent of adults living with HIV are women.

  Bill Gates said women today often have no choice but to depend on men not to infect them. "A woman should never need her partner's permission to save her own life," he said as the conference opened Sunday.

  The world's richest man said "stopping AIDS" is the top priority of the Bill and Melinda Gates Foundation.

  On Monday,former President Bill Clinton said more people would get tested for HIV if an aggressive effort took place to fight the stigma (耻辱) .But reducing fears of social rejection is not enough. Mister Clinton said people also need a guarantee they would get medicine to suppress (抑制) the virus.

  Researchers at the conference presented the results of a new study of HIV testing. It involved more than one hundred thousand people tested in California last year. Some received a quick test,with results in about twenty minutes. The others received a test that is more commonly used,the results takes two weeks.

  The researchers say twentyfive percent of the people who had the longer test did not return to learn the results. But that was true of only two percent of those who had the quick test.

  George Lemp of the University of California led the study. He says quick tests could be especially important in developing countries with limited transportation.

Speakers at the AIDS conference also discussed high rates of new HIV infections among black Americans. Julian Bond is chairman of the NAACP,a leading civil rights group. He said African-Americans must,in his words , " face the fact that AIDS has become a black disease."

5. B本篇为第16届国际艾滋病会议的报道，属于医学报道，所以答案为 B.

6. C从文章中的2、3、4段可知妇女没有防范措施，属于最易被传染的对象，所以C项正确。

A项中的美国無人感染的几率高，不是本身易感染;Clinton的意见是仅仅让人们接受艾滋病患者是不够的，还需有免疫药品，所以B不对；从文中的7、8段可知HIV的快速检测没有被广泛使用，所以D项不对。

7. B从上下文可知，epidemic意为"传染病"，所以B项正确。

8. B从全文可知，本次会议的重点是如何有效地防范艾滋病的传播。

9. B从文中可推断人们越来越关注AIDS了，所以B项正确。C项为文中直接的表述，不是推断。

  The Harry Ransom Humanities Research Center's exhibition "The American Twenties" explores the decade's great cultural and social changes,including ambiguities (模梭两可) ， contradictions (自相矛盾) ，contrasts and conflicts as well as the many ideas that were born or started to have results in the1920s.

  Featuring more than400 items,the exhibition presents the achievements and events that characterized the period. The exhibition runs from Jan. 30 to July 29at the Ransom Center at The University of Texas at Austin.

  With the opening of this exhibition,the Center begins its celebration of its 50th anniversary year." The American Twenties" is the first of one of many exhibitions and programs planned in a year contributing to" Celebrating the Imagination."

  "This exhibition is an exploration of the1920s through the literature and art that was to become typically American and typically modern."

  The United States came out from World War I with wealth and power and an urge to remake itself. In the decade's struggle to define the future of America,a large number of issues were argued and fought out in poetry,novels,political tracts (小册子) ，music and the movies. The exhibition takes a deeper look at many of the most important events and ideas that shaped the period.

  As these fundamental issues came to the surface,the idea of the "modern" became clear and the" American" century born.

  "The exhibition offers visitors a unique opportunity to witness the emergence of a distinctly modern American culture," Phillips said.

"The American Twenties" can be seen at the Ransom Center Galleries on Tuesdays through Fridays from10 a.m. to5 p.m., with extended Thursday hours until7 p.m.. On Saturdays and Sundays the galleries are open from noon to5 p.m.. The galleries are closed on Mondays.

  Fear can be fun. Many young people queue up to ride very fast and scary roller coasters,screaming but enjoying themselves. Other people like to read " goose bumps" books or watch horror movies at night,scared to death but feeling excited. Why do people like being scared? Fear is an ancient way of surviving. Being scared makes animals(including humans) flee from danger and save themselves. Scary movies It is because of fear that we have lived through millions of years of evolution. Those who lacked a strong fear response were more likely to be killed,leaving the more timid and careful to pass their genes onto the next generation.

  How do scientists explain why shivering over such scary things is fun?

  "Some kids will go to a scary movie and love it and laugh over it,others will feel anxious and hide their faces and some won't even set foot in the cinema," said Ned Kalin,a US scientist. "Which kind of person you are depends partly on experiences you've had and partly on your genes."

  What happens in the brain when something frightens you?

  Nerves that begin at the eyes and ears lead to a part of the brain called the amygdala. When you suddenly see a snake,for example,the amygdala makes you freeze,perspire (流汗，出汗) ，have a quickened heartbeat,or run very fast.

However,seeing the snake also uses another part of the brain,the cortex (皮层) .It analyzes the situation,and if it finds that the snake is only made of rubber,it tells your heart and the rest of your body to calm down. Think of the amygdala as the engine and the cortex as the brake.

Back to the first question：Why do some people like to make themselves scared? Feeling of power

  "One reason is that we can play games with fear,find ways to reduce the scariness by looking away or thinking of something else," Kalin said. "To believe we have control over a situation gives us a feeling of power. Scary movies or novels are good practice to prepare young people for the real thing. Thrills such as roller coaster rides also go to the brain's pleasure center."

  And there might be some evolutionary advantage to being able to adjust this system that is there to protect people.

   A. Why many horror films are very popular in the world.

   B. Why most people like the feeling of being scared.

(   ) 7. Which of the following is NOT the writer's opinion about Fear?

   A. Fear is a very useful way in the evolution of human beings.

   B. Your genes will partly decide your reaction to being scared.

   C. Some fear experiences can help young people in real world.

   D. Being scared can give us a feeling of power.

(   ) 8. Which of the following can best explain the underlined phrase "the amygdala as the engine and the cortex as the brake"？

   A. In some special situation,amygdala can make you nervous while cortex can make you calm down.

   B. The amygdala can make you run fast while cortex can make you stop at once.

   C. With amygdala and the cortex,you can drive a car very well.

   D. Amygdala can make you think quickly and cortex can let you stop thinking.

   Warmer sea temperatures could worsen the widespread destruction of coral reefs that hit the Caribbean in 2005,scientists fear.

  In the waters around the US Virgin Islands,as much as 40 percent of coral died in some reefs last year,and the coral that survived probably isn't healthy enough to survive another hot summer,said Caroline Rogers,a US Geological Survey biologist.

Reefs are vital habitat for fish,lobsters and other sea life that feed and breed in the sheltered waters. The reefs also change storm waves that might otherwise wash away the beaches that are at the heart of the region's multibilliondollar tourism industry.

  "You don't know how scary it looks down there," said Zandy Starr,who monitors coral and sea turtles in St. Croix's national parks. "All of us thought that by now,with all the cooler temperatures in January and February,we would have seen recovery,but they're still sick."

  Glassy,calm seas have permitted coralkilling ultraviolet (紫外线的) rays to access to the ocean floor,warming water temperatures and making the fragile (易碎的) undersea life more sensitive to disease,Starr said.

Scientists haven't pinpointed (准确地说出) what caused coral to become sick or led to the warm water,which stresses coral and makes it more susceptible (敏感的) to disease. They can't say whether global warming is a factor.

  "We don't really have the data. You need a record over decades. There's a lot of research that needs to happen”，said Alberto Sabat,a biology professor at the University of Puerto Rico.

But the trend of warmer waters isn't limited to the Caribbean. The National Oceanic and Atmosphere Administration said waters were warmer than usual in the South Pacific,mid-Atlantic and Indian Ocean in mid-April.

  Rogers said coral grew far better after hurricanes that devastated (摧毁) the US Virgin Islands in 1989 and 1995 because the storms cooled the sea,allowing reefs to recover relatively quickly from damage.

Rising temperatures appear to be "something new that the corals aren't used to," said Tyler Smith,a marine researcher at the University of the Virgin Islands.

The scientists worry that the problem is being overlooked,

  "People just don't know that much about coral because it's underwater. If 40 percent of the trees ill one of our national parks died,people would take notice”，Rogers said.

(   ) 5. The underlined word "overlooked" in the passage means         .

   A. to have a view from above   B. to fail to notice   

    C. to pay attention to   D. to guide somebody

   A. it is the necessity for the sea life

   B. it can prevent the global warming spreading

   C. it can make the beach more beautiful so that people can earn more money

   D. it can offer a shelter not only for the human being but also for the fish

(   ) 7. The example of hurricanes given by Rogers is to show         .

   A. coral reefs don't like the warm water

   B. hurricanes are good for the growing of coral reefs

   C. the global warming is terrible for coral reefs

   D. how to cure the sick coral reefs

(   ) 8. What can we infer from the passage?

   A. More and more areas will face the coral problem.

   B. The survived coral is being recovered this year.

   C. Most people have noticed the seriousness of the problem.

   D. Calm seas are good for the coral growing.

(   ) 9. What is the best title for the passage?

   A. A Research Report on the Coral Problem

I pause for a(n) 13      ,reset myself,and tell myself I am going to kick it straight down. What happens? About half the time I kick it 14       ,and the other half,I fail it. But at the very least I increase my 15        of performing better. Bad thoughts almost guarantee failure,16       good thoughts increase success.

   Street art can be found on buildings,sidewalks,street signs and even trash cans from Tokyo to Paris to New York City. This special kind of art can take the form of paintings,sculptures,cloth or even stickers. Street art has become part of a global visual culture. Now,even art museums and galleries are collecting the work of street artists.

  It is not easy to provide an exact history of the street art movement. This kind of art has developed in many kinds of ways in places all over the world. Also,because it is illegal to paint public and private property without permission,street artists usually work secretly. This secretive nature of street art and its countless forms make it hard to define exactly. And people have different opinions about the movement. Some think street art is a crime and destroys property. But others see this art as a rich form of nontraditional cultural expression.

  Many experts say the movement began in New York City in the nineteen sixties. Young adults would use paint in special cans to spray their "tag" on walls and train cars around the city. This tag was a name they created to identify themselves and their artwork. This colorful style of writing is also called graffiti. It is visually exciting and energetic.

  Graffiti also became a separate movement expressing the street culture of young people living in big cities. Graffiti art represented social and political rebellion. These artists could travel around areas of the city making creative paintings for everyone to see. Sometimes this street art created a dispute between artists and city officials. Graffiti artists created their images and city officials quickly painted over them.

  During the 1980s,two famous New York painters―Keith Haring and Jean Michel began showing their work in art galleries and museums. This is when street art started to become part of the more general popular culture.

  California pet lover has founded an internet radio station designed to ease the lives of lonely dogs and cats around the world.

  Styled as " the radio station all pets prefer"，DogCatRadio.com goes out live 17 hours each day from a van in the car park of a Los Angeles recording studio.

  DJs speak to pets directly,and ask " pet parents" to send in pictures.

  Founder Adrian Martinez,34 ，says the station aims to keep pets company while their "parents" head out to work.

  Mr. Martinez,an independent record producer,hopes that many of his audience will be listening in while at home alone,albeit (虽然，尽管) with a little help from their human friends.

  "My cat,Snickers,asked me to do it," Mr. Martinez told the New York Times. Faced with a nervous,restless cat at home one day,Mr.  Martinez discovered that Snickers calmed down almost as soon as he turned up the background music a little. "I wanted to do something for the pet community," he said.
