问题 This passage mainly discusses how epidemics spread and how to prevent in advance.
All epidemic diseases spread through people’s sneeze, human contact and insects.
选项 A、Y
B、N
C、NG
答案B
解析 本题涉及到流行病的传染方式，应锁定文章第五至七段。第五段提到Some...are spread when people’s sneeze...；第六段提到Others are spread through human contact；第七段提到Other diseases are spread through insects，很容易使人误以为题干表述正确。然而如果注意到了第五段首句的总起性语言Doctors know how most epidemic diseases spread，就不难明白：并不是所有的流行病都会传染。题干中的All与文中的most矛盾，所以本题表述错误。
