问题     More people die of tuberculosis (结核病) than of any (1)______
disease caused by a single agent. This has probably
been the case in quite a while. During the early stages of (2)______
the industrial revolution, perhaps one in every seventh (3)______
deaths in Europe’s crowded cities were caused by the (4)______
disease. From now on, though, western eyes, missing the (5)______
global picture, saw the trouble going into decline. With
occasional breaks for war, the rates of death and infection
in the Europe and America dropped steadily through the (6)______
19th and 20th centuries. In the 1950s, the introduction
of antibiotics (抗菌素 ) strengthened the trend in rich
countries, and the antibiotics are allowed to be imported (7)______
to poor countries. Medical researchers declared
victory and withdrew.
    They were wrong. In the mid-1980s the frequency of
infections and deaths started to pick up again around the
world. Where tuberculosis vanished, it came back; in (8)______
many places where it had never been away, it grew better. (9)______
The World Health Organization estimates that 1.7 billion
people (a third of the earth’s population) suffer from tuberculosis.
Even when the infection rate was falling, population
growth kept the number of clinical cases more or less
constantly at 8 million a year. Around 3 million of those (10)______
people died, nearly all of them in poor countries.
