16. 【答案】B
【解析】依据下文中的"it feeds on human blood, transporting numerous diseases—It's the mosquito "可知，所选句中含有"蚊子" 或相关的词语，故B项符合语境，选项中的"this thing"指上文提 到的"the deadliest animal"，也就是蚊子。
17. 【答案】F
［解析】上一句列举了被蚊子叮咬后产生的疾病，F项是对上一 句的延伸，说明疟疾给人带来的伤害，符合语境。
18. 【答案】G
【解析】该段主要讲了蚊子繁殖很快，结果数量太多，我们难以 避免被叮到。再根据第三段中的"Being able to adapt easily—one of the reasons"可判断，该部分内容是关于蚊子致命的另一个原 因，故G项符合语境。
19. 【答案】D
［解析】上一句表明世界各地的人们都难以避免被蚊虫叮咬，D 项中的"every bite increases the risk"是对上一句的延伸。
20. 【答案】C
［解析】上文提到，Bernard Cohen教授建议我们应该避开水多 的地方以免遭蚊叮。下文中的"Wear bug repellent （驱虫剂）"是保 护自己的具体做法，所以空处应是这位教授的另一个建议。
