Sitting and eating quietly on his father’s lap, the 18-month-old was oblivious to the infection in his veins(血管).But his father a strong farmer, knew only too well. It was the same one that killed his wife four month ago, leaving him alone with four children. The man started to cry.
“When my wife died, I thought ,well, it is from God, but at least I have him.” he said. “Then I learned he is sick, too. I asked if there was medicine and the doctors said no.
HIV and AIDS have quietly arrived in this land. They remain almost completely underground, hidden in ignorance（无知）and shame.
The father of the infected 18-month-old said his village teacher had never talked about AIDS. Nearly a year of tests on the father have found no HIV, and the old children are clear, but his smallest child tested positive（阳性）at ten months.
Six years earlier, his wife lost a baby and have several transfusions in Pakistan. After she became sick and was found to be infected, “I told the family her blood was not good and to avoid eating with her.” he said. “And I told them not to kiss his son, he burst into tears.
“I don’t know what to do,” he said; “I have sacrificed so much since my marriage.. I mortgaged (抵押)half my land to pay for her medical care.”
The father can do little for his son but keep his secret. There are no AIDS treatment centers in Afghanistan, only a single secret clinic in the capital that just monitors the disease, and no drugs are available.

 Space is a dangerous place. not only because of meteors (流星) but also because of rays from the sun and other stars. The Atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.

    Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem”. Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed (畸形的) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.
