(判断)AIDS, fifty years ago, didn’t exist.Fifteen years ago a few doctors and public health officials noticed the first cases.Within a few years it was clear that it has now killed almost 14 million people around the world.
Four years ago doctors came up with the first treatment to make a dent in the spiraling death rate.Today that treatment works for some patients, but it’s not clear how long results will last.And still there is no cure.
For the nearly 35 million people around the world now living with HIV, there may never be a cure.Once cells are infected with HIV, it is very difficult — perhaps impossible ―to rid them of the virus.The only sure way to stop AIDS is to prevent infection in the first place, and only a vaccine can do that.
Unfortunately HIV is one of the most changeable viruses known to science.After more than a dozen years, it is still rather difficult to produce effective vaccine.
Still the billions of dollars spent on AIDS research over the past 20 years has not been wasted.As scientists learn more about how HIV survives in the human body, they are realizing that drugs alone may not be enough.To contain the virus effectively, it may take a balance between drug treatments that can keep HIV levels low and a strengthened immune system that can then target and destroy the remaining virus.Until scientists find a vaccine, however, they may control but never cure the century’s final scourge.
46.AIDS didn’t exist fifteen years ago.
47.Scientists have found a vaccine which can prevent HIV infection.
48.Although some treatment works for some patients with HIV, there is still no cure.
49.HIV is a changeable virus so that it is very difficult to produce effective vaccine.
50.We have wasted billions of dollars on AIDS research.
This trend is called "population fatigue", and it's beginning in many of the developing countries that have experienced【3】birthrates and sharp population growth for several decades. Governments in these countries are now having trouble dealing with feeding, housing and educating an increasing number of children,【4】at the same time confronting the falling water【5】, deforestation and soil erosion that rapid population growth brings. In these countries any new threat—infectious disease, drought or famine—can become a【6】crisis.
AIDS is a case【7】. WHO estimates calculate that one-quarter of the adult population of Zimbabwe and Botswana are infected with the AIDS virus,【8】, these countries stands to lose at least one-quarter of their labor force in the next decade from AIDS alone, a situation【9】since the yellow fever swept through Europe in the 14'h century.
Social unrest is also increasing in these countries. One example is the【10】conflict between the Tutsis and the Hutus in Rwanda, where population pressures reduced cropland【11】where it could no longer feed those who lived on it. Demands on the world fisheries and shared water resources are likely to spark similar conflicts. Already the waters of the Nile are so heavily used that little reaches the Mediterranean, so any increase in demand or【12】in allocation will also increase tensions.
The bottom line is that human population growth is【13】to slow one way or the other. Developing societies will either recognize problems【14】the horizon and act to encourage smaller families — or unchecked births will have their【15】in rising death rates.

Like every dog, every disease now seems to have its day. World Tuberculosis (infections disease in which growths appear on the lungs) Day is on Saturday March 24th.
Tuberculosis was once terribly fashionable. Dying of "consumption" seems to have been a favorite activity of garret-dwelling 19th-century artists, h has, however, been neglected of late. Researchers in the field never tire of pointing out that TB kills a lot of people. According to figures released earlier this week by the World Health Organization, 1.6 million people died of the disease in 2005, compared with about 3m for AIDS and I'm for malaria. But it receives only a fraction of the research budget devoted to AIDS. America's National Institutes of Health, for example, spends 20 times as much on AIDS as on TB. Nevertheless, everyone seems to getting in on the TB-day act this year.
The Global Fund an international organization responsible fur fighting all three diseases but best known for its work on AIDS, has used the occasion to trumpet its tuberculosis projects. The fund claims that its anti-TB activities since it opened for business in 2002 have saved the lives of over 1m people. The World Health Organization has issued a report that contains some good news. Although the number of TB cases is still rising, the rate of illness seems to have stabilized; the caseload, in other words, is growing only because the population itself is going up.
Even drug companies are involved. In the nm-up to the day itself, Eli Lilly announced a $50m boost to its MDRTB Global Partnership. MDR stands for multi-drug resistance, and it is one of the reasons why TB is back in the limelight. Careless treatment has caused drug-resistant strains to evolve all over the world. The course of drugs needed to clear the disease completely takes six mouths, anti persuading people lo stay that course once their symptoms have gone is hard. Unfortunately, those infected with MDR have to be treated with less effective, more poisonous and more costly drugs. Naturally, these provoke still more. non-compliance and thus still more evolution.
The other reason TB is back is its relationship to AIDS. The (global Fund's joint responsibility for the diseases is no coincidence. AIDS does not kill directly. Rather, HIV, the virus that causes it, weakens the body's immune system and exposes the sufferer to secondary infections. Of these, TB is one of the most serious. It kills 200,000 AIDS patients a year. However, some anti-TB drugs interfere with the effect of some anti-HIV drugs. Conversely, in about 20% of cases where a patient has both diseases, anti-HIV drugs make the tuberculosis worse. The upshot is that 125 years after human beings worked out what caused TB, it is still a serious threat.
The first sentence "Like every dog, every disease now seems to have its day". means ______.
A.every dog enjoys good luck or success sooner or later.
B.human beings can deal with problems caused by disease.
C.Tuberculosis becomes a serious infectious disease.
D.people attach importance to Tuberculosis recently.
