[单项选择]
When Melissa Mahan and her husband visited the Netherlands, they felt imprisoned by their tour bus. It forced them to see the city according to a particular route and specific schedule—but going off on their own meant missing out on the information provided by the guide. On their return home to San Diego, California, they started a new company called Tour Coupes. Now, when tourists in San Diego rent one of their small, brightly coloured three-wheeled vehicles, they are treated to a narration over the stereo system about the places they pass, triggered by Global Positioning System (GPS) satellite technology.
This is just one example of how GPS is being used to provide new services to tourists."What we really have here is a technology that allows people to forget about the technology," says Jim Carrier of IntelliTours, a GPS tourism firm which began offering a similar service over a year ago in Montgomery, Alabama.

[不定项选择题]共用题干
Women with AIDS
For a long time women with HIV were ignored because the focus was totally on HIV men.The gay community was very much in sight and vocal and successfully got support for its cause.Now we are rapidly approaching the point where about one haff of all AIDS cases in the. world are women. But no one is taking this dangerously high level of infection among women seriously enough.
Women usually have a worse time dealing with HIV than men do.In most cases,the woman is taking care of children as well as her sick partner. She may not even have time to take care of herself. The HIV-positive woman ends up shouldering the family as well as her own personal problems. Men,however,are usually the ones who have insurance income and access to doctors.They get care.Women often do not.
The discrimination against HIV-positive women is simply terrible.They are likely to be more inactive than men in the home and workplace because too many people think that women are the cause of the disease.This is not at all true.They get it from a man.They don't just simply have HIV.Of course,there's a social discrimination against all people with HIV.They are scared that other people will know they are HJV-positive and that they will,therefore be discriminated against. For example,it's very difficult for people with HIV to travel.They are not allowed to enter many countries,including the United States,China and Russia.
The biggest difficulty an HIV-positive woman must face is the isolatjon.Once the woman knows she's HIV-positive,she lives in fear that other people will find out.She's so frightened she will go into hiding,into an isolated place by herself. It's not at all uncommon to meet a woman who has been HIV-positive for nearly 10 years and has never told anyone,except her doctor. And the resulting stress is enough to make her sick.But HIV-positive women who get support,who can discuss their trouble and then do something about it一whether that means taking better care of themselves or going to the United Nations to struggle for their rights一are likely to live longer. Active women don't die out of shame in a corner. This happens to too many HIV-positive women.
There is social discrimination against only women with HIV.
A.Right
B.Wrong
C.Not mentioned
