　　参考答案及解析：

　　1.^which-in　此处的介词其实是和live连用的，live in the environment。

　　2.deal^-with。deal with是固定搭配，意思是“解决，处理”。

　　3.make^-way。根据上下文可以断定此处文章要说的是“人们烧，伐树木为的是给开垦农田让路。”make way for something。是“给……让路”，符合此处需要的意思。

　　4.spread-polluted/littered。这里的关键是要知道debris的意思是“碎片，残骸等”，所以根据上下文这里的`意思是“湖泊和湿地被一些碎片残骸所污染或弄得凌乱不堪”才符合逻辑。

　　5.^Abundan-the。此处不是泛指，而是特指，所以要有定冠词。

　　6.as-like。此处是拿中国举例，所以要用介词like“像……一样”。

　　7.cause-causing。此处定于分句是主动的意义。

　　8.variant改为various。variant是“变体的，变种的”，而various表示“不同的”，符合此处意思。

　　9.get^of-rid。固定搭配get rid of 是“摆脱”的意思。

　　10.rise-arise

　　part 2

　　In the 1950s, the introduction of antibiotics strengthened the trend in rich countries, and the antibiotics were allowed to be imported to __6__ poor countries. Medical researchers declared victory and withdrew.

　　They are wrong. In the mid1980s the frequency of infections and deaths __7__ started to pick up again around the world.

　　Where tuberculosis vanished, it came __8__ back; in many places where it had never been away, it grew better.

　　The World __9__ 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 __10__ million a year. Around 3 million of those people died, nearly all of them in poor countries.

　　参考答案及解析:

　　tuberculosis n.肺结核

　　antibiotics n.抗生素, 抗生学

　　1 将in改为for

　　2 将seventh改为seven

　　3 将were改为was

　　这个谓语动词的主语是单数短语 one in every seven deaths, 因此要使用单数.
