问题 This passage mainly discusses how epidemics spread and how to prevent in advance.
Epidemic diseases can be prevented by means of vaccination or ______.

选项

答案good health habits

解析本题涉及到流行病的防治，需锁定文章第十段．综合该段首句Some diseases can be prevented by vaccination和第三句Other diseases can be prevented by good health habits很容易得知，流行病有两种预防方式，接种疫苗和保持良好的健康习惯，故本空应填good health habits。
