选项 A、Germs can be found both in water and air.
B、If your finger isn’t cut, there aren’t any germs on it.
C、Germs can go into your finger if your finger is cut.
答案B
解析 文章最后一段第一句话指出：Germs aren’t found only in water. They are found in air and dust. 所以选项A的陈述是正确的，即水和空气中都可找到细菌。选项C：如果你的手指破了，细菌可能会进人手指，符合最后一段中提到的细节。这个选项也是正确的。选项B：如果你的手指不破，就没有细菌附着在手指上是错误的。错在介词“on”上。根据文章内容，介词“on”应该改为“in”。手指不破，细菌就不会进入手指。既然空气中、水中都会有细菌，人的手指一定会接触空气和水。
