Different forms of maps are appearing．They allow independent travelers to get local knowledge of places they are visiting, from the official to the unusual．Meanwhile, hi-tech developments are creating new ways for us to map the world．Here are two of our favorites;
Green Maps
Green Maps allows people to share with the world their knowledge of environmentally friendly places and attractions in the local areas．Users add information with a set of icons(图标),making it easy to read any map ,whatever the nationalities of those who produce it．At present there are over five hundred Map projects being developed in 54 countries Green Maps’ advertised idea is “think global, map local”．It is a wonderful way of gaining all sorts of a place, ranging from community garden to good places of bird watching．
Green Maps is not specifically intended for travelers．Not all of its maps are online, so it may be necessary for some users to communicate with producers through the Green Maps website．
Maps Mashups
Many people use online maps developed by Google, but not many know about the mashups of them．Working in a similar way to Green Maps, Maps Mashups allows people to add icons of their own to existing maps to express a certain topic．The mashups is so called because it combines all the knowledge you could ever need．It ranges from the extremely useful, such as where all the World Heritage Sites are, to the most bizarre(古怪的)，such as where America’s munkest cities are．With the mashups added to the basic Google Maps, a multi-layered(多层的)map can be created．

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 into 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．
