She cooked, cleaned and looked after her two small children. Last year, her life took a tragic turn. Her husband died of AIDS; she was found out HIV-positive (艾滋病病毒检验呈阳性反应) and her mother-in-law took her children away from her, saying they would get the disease. “When friends dropped in for a visit, she would introduce me, saying, ‘She is my son’s widow. She has AIDS,’" said Mala. AIDS is now described as "explosive (炸药) "around the world. A study of a hospital in the port city of Durban in south Africa, where the world’s biggest and Africa’s first AIDS conference opened last Sunday, found that almost half the beds in medical wards (病房)were occupied by AIDS patients. South Africa has one of the world’s fastest growing HIV infections(传染), with 1,700 people infected daily, adding to the 4.3 million, or 10 percent of its population, living with HIV. Until now, Asia has been more successful in holding the AIDS virus(病毒) than Africa, where the disease has killed about 12 million people. AIDS is now threatening to surround many of Asia’s poverty-stricken countries. Countries in Asia, such as Cambodia, and Thailand, have HIV infection speeds over 1 percent. But the low speeds hide huge numbers of affected people, because of the population base. In India, for example, 3.7 million are infected, more than in any other country except South Africa. In China, an estimated 500,000 people, mainly drug users, live with HIV/ AIDS. Gordon Alexander, a senior advisor for UN AIDS in India, estimates(估计) that the number hit by AIDS in Asia will climb to about eight million over the next five years from about six million. In many Asian countries, the battle against HIV is a social cultural one against public discussion of sexual health and put a nationwide media campaingn into action to limit the spread of HIV through unsafe sex. Brenton Wong, an official with Singapore’s Action for AIDS, says the actual HIV incidence in the city state of 3.9 million people is at least eight times higher than official data. “Shame and deny is still very, very common so people are afraid to get tested and many times won’t even tell their families if they test positive,” said Wong.

Thailand (C) ars ago, Mala was a typical middle-class Indian What was it like to live in space? Imagine orbiting (环轨道运行) the earth once every ninety-three minutes. Imagine traveling through space at more than twenty-seven-thousand kilometers an hour. That is what the skylab astronauts did. During that time they ate, slept, and did most of the things people do on the earth. But there was one big difference. There was no gravity. Gravity is the force that holds us down to the earth. Skylab was beyond the reach of the earth's gravity. People and objects were weightless. They floated freely unless held down. At times, the skylab astronauts enjoyed the 1ack of gravity. They could float like bubbles through the spaceship. They could hang upside down like bats(蝙蝠). They could do sticks like circus acrobats(杂技演员). At other times, however, they did not enjoy the lack of gravity. with no gravity, their food new right off the plate. And a dropped tool just floated away. Skylab was a space house. But living and working in it were very different from living and working in a house on the earth. Skylab had a workshop, a s1eeping area, a kitchen, and a bathroom. Unlike a bedroom on the earth, the sleeping area did not contain beds. It had hanging bags. The astronauts slept standing up in the bags. They could not lie flat in a normal bed, because they would float off. The bathroom in skylab had a shower. So, the astronauts could wash themselves. The shower was completely closed in. This was necessary to prevent the water frome floating throughout the spaceship. Water and wastes had to be pulled by pipes into storage containers. The astronauts in skylab wore shoes that had special devices on the bottoms. These devices linked with similar devices on the floor of the spaceship. This kept the astronauts in one place as they worked or ate. On the two earlier flights, astronauts had eaten from tubes(管) or bags. They just squeezed(挤压) the food into their mouths. On skylab, eating was a more normal activity. The astronauts ate bread, meat, vegetables, and fruits. They stored the food in freezers. They warmed it in special heating devices. Magnets (磁铁) held down their knifes, forks, and spoons. Covers kept the food from floating away. The astronauts drank water and other liquids from p1ashc container similar to baby bottles.
