a. by working and social experience. b. learning from her friends. c. through an unfortunate experience. d. because of her children and husband. 18. the underlined sentence it is so easy to exist instead of to live in the fifth paragraph probably has the same meaning as a. it is so easy to keep alive but not to live a real life b. it is very hard to live a real life c. it is so easy to make a living d. it is more difficult to exist than to live a happy life19. whats the authors attitude toward work? a. do it well to serve others. b. to earn enough money to make life better. c. try your best to get higher position and pay. d. dont let it affect your real life.20. it can be inferred from the passage that a. the author is a success in personal life b. the author didnt try her best to work well c. the author spent all her time caring for her children d. the author likes traveling very much b 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 dont 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.21. it can be inferred from the passage that a. antiretroviral drugs will be obtained easily all over the world b. the best way to stop aids is to develop a vaccine b. scientists will soon find a way to cure aids d. there will be fewer aids cases in the world in the future22. which areas are the most worrying places where aids spreads quickly?
