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

We are often asked to make a speech in life. Most of us are afraid of it and don’t do a good job. Here are some simple steps to make your speech a successful one.

I have a rule for travel: Never carry a map. I prefer to ask for directions
Foreign visitors are often puzzled in Japan because most streets there don’t have names. In Japan, people use landmarks in their directions instead of street names. For example, the Japanese will say to travelers, “Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop.” In the countryside of the American Midwest, usually there are not many landmarks. There are no mountains, so the land is very flat. In many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, “Go north two miles. Turn east, and then go another mile.”
People in Los Angeles, California, have no idea of distance on the map: they measure distance by means of time, not miles. “ How far away is the post office?”
You ask. “Oh,” they answer, “ It’s about five minutes from here.” You say, “Yes, but how many miles away is it?” They don’t know.
People in Greece sometimes do not even try to give directions because visitors seldom understand the Greek language. Instead of gibing you the direction, a Greek will often say, “ follow me.” Then he’ll lead you through the streets of the city to the post office.
Sometimes a person doesn’t know the answer to your question. What happens in this situation? A New Yorker might say, “Sorry, I have no idea.” But in Yucatan, Mexico, no one answers, “I don’t know.” People in Yucatan think that “ I don’t know” is impolite. They usually give an answer, often a wrong one. A visitor can get very, very lost in Yucatan!
One thing will help you everywhere ---- in Japan, in the United States, in Greece, in Mexico, or in any other place. You might not understand a person’s words, but maybe you can understand his body language. He or she will usually turn and then point in the correct direction. Go in that direction, and you may find the post office!The passage mainly tells us that ______________.
A there are not many landmarks in the American Midwest
B never carry a map for travel
C there are different ways to give directions in different parts of the world
D New Yorkers often say, “I have no idea,” but people in Yucatan, Mexico, Never say thisThe passage says, “ In Japan, people use landmarks in their directions.” The word “landmark” means _______.
