Malaria, the world's most widespread parasitic(寄生虫引起的) disease, kills as many as three million people every year-almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.

Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect (感染). They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth-and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.

For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.

A would stop working at night     B would stay on in San Francisco

C would make friends with cleaners.    D would give up her job at the bank

C

      When I met him, I had a lot of anger inside of me. I‘ve lived my whole life in Spanish Harlem, but in my neighborhood, there are shoot-ups all the time. I know kids who have been shot or beaten up. I have friends who ended up in prison. I could have ended up that way, too, but Mr. Clark wouldn’t let that happen.

       Mr. Clark worked long hours, making sure I did my work. My grades rose. In fact, the scores of our whole class rose. One day, he took our class to see The Phantom of the Opera, and it was the first time some kids had ever been out of Harlem. Before the show, he treated us to dinner at a restaurant and taught us not to talk with our mouths full. We did not want to let him down.

      Mr. Clark was selected as Disney‘s 2000 Teacher of the Year. He said he would draw three names out of a hat; those students would go with him to Los Angles to get the award. But when the time came to draw names, Mr. Clark said, “You’re all going.”

      On graduation day, there were a lot of tears. We didn‘t want his class to end. In 2001, he moved to Atlanta, but he always kept in touch. He started giving lectures about education, and wrote a bestselling book based on his classroom rules, The Essential 55. In 2003, Mr. Clark took some of us on a trip to South Africa to deliver school supplies and visit orphanages (孤儿院)。 It was the most amazing experience of my life. It’s now my dream to one day start a group of women‘s clubs,

    helping people from all backgrounds.
