On June 5, 1981 the Centers for Disease Control in Atlanta, U.S. announced the presence of a rare, infectious disease in five American homosexuals(同性恋). Soon doctors were finding similar cases all over the country and the world. The AIDS epidemic(流行病)had officially begun. By 1983 it was clear that AIDS had spread around the world. More than twenty years later, AIDS has left twenty-six million dead and another forty million infected.  AIDS has become the worst medical disaster ever experienced by mankind.

Hundreds of young people between the ages of 20 and 45 died each week during the early years of the U.S. AIDS. More than 600,000 cases of AIDS have been reported since 1981 in the United States, and it is estimated that there may be as many as 900,000 Americans infected with HIV.

Though the rate of HIV infections continues to increase in the United States, the number of AIDS cases has fallen sharply since 1996, when antiretroviral drugs came onto the market. Unfortunately, the AIDS epidemic continues today in Africa and much of Asia, where antiretroviral treatment is not available and health care is far from enough. AIDS is the fourth leading cause of death worldwide, and the No. 1 cause of death due to infectious disease.

HIV, the virus that causes AIDS, was first separated in 1983 by a team at the Pasteur Institute in Paris. That discovery made it possible to develop a test for AIDS and trace back to victims who may have died before doctors were aware of the disease.

However, scientists still don't know exactly how and where AIDS started. Finding the source of AIDS could be important in developing a vaccine(疫苗) and be important in mapping the future course of the epidemic.

It can be inferred from the passage that       

     A．antiretroviral drugs will be obtained easily all over the world

     B．the best way to stop AIDS is to develop a vaccine

     B．scientists will soon find a way to cure AIDS

     D．there will be fewer AIDS cases in the world in the future

Which areas are the most worrying places where AIDS spreads quickly? 

     A．Africa.               B．Asia.             C．The United States.               D．France.

The number of AIDS cases has greatly decreased in the United States due to the fact

     A．a team at the Pasteur Institute in Paris succeeded in separating HIV

     B．some effective medicine has been invented

     B．scientists understand AIDS better and better.

     D．The rate of HIV infections continue to rise in the United States

What's the importance of the discovery of the source of AIDS?

    A．It can be used to develop a test for AIDS.

     B．It can stop HIV forming AIDS.

     B．It can reduce the rate of death caused by AIDS.

     D．It can help develop a drug to prevent AIDS.

Grace Kane hangs onto an Olympic dream of clinging to a granite (花岗岩) wall by her fingertips 70 feet from the ground. The fearless girl is only 10, but already has scaled great heights in the sport of rock climbing.

Last week, Kane won a bronze in the 11­and­younger sport class at the USA Climbing Youth National Championships in Atlanta. She was the only competitor of the 31 there with no climbing coach or top­flight facilities in which to train. Climbing will become an exhibition at the 2016 Rio de Janeiro Olympics in Brazil. The hope of enthusiasts is that the sport will gain full status in 2020.“I’m already training for that,” said Kane. “Climbing is my passion, my love, and I want to make something of it.”

Her dad took her to climb rocks on her fourth birthday for the first time and today he can’t keep up with her, “It’s the freedom to let loose,” she said. “When I’m up there, I’m so focused and don’t hear anything. I always feel comforted knowing people are supporting me.”

The bronze in Atlanta qualified Kane for the USA team and November’s International Championships in Ecuador. That’s a trip she might have to miss because it’s too expensive.

Kane held a backyard music concert---she played the guitar and the piano and wrote inspirational songs---and raised $600 for her $1,500 trip to Atlanta. She’s also been sponsored by a shoe company, but must rely heavily on donations from family and friends for travel expenses.

Her mom Heather Kane said the family has chosen “to do whatever we need to help her achieve her goals”. One of Grace’s biggest challenges is finding balance in her life. There’s school, her music and church to fit around climbing.

“Climbing is going to mean sacrificing things other kids might pursue,” Grace said. “But it doesn’t bother me. It’s like playing the piano; you can’t take a break or you’ll lose your touch.”

1.What would be the best title of the passage?

A. Rock climbing gains popularity

B. Grace Kane likes challenges

C.A young climber follows her dream

D. An amazing victory for a young rock climber

2.We can learn from the second paragraph that rock climbing ________.

A. is not an exhibition at the Olympics now

B. is an official event at the Olympics now

C. is not open to children

D. will gain full status in 2020

3.Which of the following is TRUE about Grace Kane?

A. She is only interested in rock climbing.

B. She is a girl with many talents.

C. Rock climbing has affected her study.

D. She has won gold medals in several matches.

4.One of Grace’s biggest challenges is to ________.

A. find a capable coach for her

B. get qualified for the USA team

C. raise enough money for International competitions

D. keep balance between rock climbing and other activities
