Tuberculosis(肺结核，TB) killed 1,300,000 people arould the world in 2007. In addition, almost half a million people who were infected with tuberculosis and with HIV also died. Those were listed as HIV deaths.
About one-third of all people are infected with tuberculosis. But the body’s natural defenses are usually strong enough to prevent an active case. Even so, the bacteria remain in the body. If the immune system weakens at any point, they begin to spread and then attack.
The bacteria that cause TB usually settle in the lungs. They spread through the air when the person coughs or even sings and talks.
One of the most important things is to identify cases quickly. The patients need to be kept away from other people and begin treatment as soon as possible.
Multidrug resistant tuberculosis, orMDR-TB, will not get better with antibiotics normally used for tuberculosis. So doctors must use stronger, “second line “ drugs when the first ones fall.
Now, researchers say they have found a much faster way to identify drug-resistant TB. The study’s lead author is Graham Hatfull at the University of Pittsburgh in Pennsylvania.
The scientists used viruses called bacteriophages to speed the process. These viruses attack bacteria. The researchers injected them with a gene that produces green light. They also injected some with first line antibiotics and others with second line drugs.
Then they bined the bacteriophages with TB bacteria. If the bacteria produces green light, it means they are drug-resistant. The researchers say a clinic worker could identify the green light with equipment easy to get in many clinics. Test results would not have to wait for the bacteria to grow in a lab far away. For now , the test itself needs more testing. But Professor Hatfull is hopeful this will take months and not years.

网友回答
(答案→)Tuberculosis /TB
解析：
【小题1】这题填标题，也是文章的主旨，文章主要讲的是：Tuberculosis /TB
【小题2】推理题：从这一行右列的One-third of people around the world 看出是 the number of..数量。
【小题3】细节题：由第二段的：If the immune system weakens at any point, they begin to spread and then attack.看出是填：weakens，当免疫系统变弱。
【小题4】信息转换题：由第三段的：The bacteria that cause TB usually settle in the lungs.把定语从句转换成causing做定语。
【小题5】细节题：从第三段的They spread through the air when the person coughs or even sings and talks.知道填：spread。
【小题6】推理题; 从右列的内容看出是几种solutions。
【小题7】信息转换题：从第六段的researchers say they have found a much faster way to identify drug-resistant TB. 竖列都是动名词，所以用Identifying。
【小题8】细节题：从第六段的：The patients need to be kept away from other people and begin treatment as soon as possible.看出填：patients。
【小题9】这题也是细节题,同样从上面的句子看出来填：treatment
【小题10】细节题，信息是从第七段看出的，So doctors must use stronger, “second line “ drugs when the first ones fall.用文章的原词stronger就行。
