单项选择题

We were late as usual. My husband had insisted on watering the flowers in the garden by himself, and when he discovered that he couldn’t manage, he asked me for help at the last moment. So now we had an hour to get to the airport. Luckily, there were not many cars or buses on the road and we were able to get there just in time. We checked in and went straight to a big hall to wait for flight to be called. We waited and waited, but no announcement was made. We asked for information and the girl there told us that the plane hadn’t even arrived yet. In tile end, there was another announcement telling us that passengers waiting for Flight LJ108 could get a free meal voucher(凭单) and that the plane hadn’t left Spain for technical problems. We thought that meant that it wasn’t safe for the plane to fly. We waited again for a long time until late evening when we were asked to report again. This time we were given vouchers to spend the night in a nearby hotel.
The next morning after a bad night because of all the planes taking off and landing, we were reported back to the airport. Guess what had happened while we were asleep! Our plane had arrived and taken off again. All the other passengers had been forgotten. You can imagine how we felt!
The plane was delayed______.

A. by the bad weather B. by the passengers
C. because of many cars on road D. because something was wrong with the machine

Most of the world’s victims of AIDS live — and, at an alarming rate, die — in Africa. The number of people living with AIDS in Africa was estimated at 26.6 million in late 2003. New figures to be published by the United Nations Joint Program on AIDS (UNAIDS), the special UN agency set up to deal with the pandemic, will probably confirm its continued spread in Africa, but they will also show whether the rate of spread is constant, increasing or falling. AIDS is most prevalent in Eastern and Southern Africa, with South Africa, Zimbabwe and Kenya having the greatest numbers of sufferers; other countries severely affected include Botswana and Zambia. AIDS was raging in Eastern Africa — where it was called slim , after the appearance of victims wasting away — within a few years after its emergence was established in the world in 1981. One theory of the origin of the virus and syndrome suggests that they started in the eastern Congo basin; however, the conflicting theories about the origin of AIDS are highly controversial and politicized, and the controversy is far from being settled. Measures being taken all over Africa include, first of all, campaigns of public awareness and device, including advice to remain faithful to one sexual partner and to use condoms. The latter advice is widely ignored or resisted owing to natural and cultural aversion to condoms and to Christian and Muslim teaching, which places emphasis instead on self-restraint. An important part of anti-AIDS campaigns, whether organized by governments, nongovernmental organizations or both, is the extension of voluntary counseling and testing (VCT). In addition, medical research has found a way to help sufferers, though not to cure them. Funds for anti-AIDS efforts are provided by the Global Fund to Fight AIDS, Tuberculosis and Malaria, a partnership between governments, civil society, the private sector and affected communities around the world; the fund was launched following a call by the UN Secretary-General in 2001. However, much more is needed if the spread of the pandemic is to be at least halted.
