Bats like living in dark and wet places. There are all kinds of viruses(病毒).
Bats always live groups, so the viruses can have larger "playgrounds" to grow and become powerful.
Bats are like humans in some way. Our similar genes (基因) make easier for us to become sick with the same viruses.
When bats fly, their body temperature can reach as as 40℃. Such temperature can kill weak viruses, but stronger ones will be alive and continue to grow. Bats have special protection systems allow them to live with viruses without getting sick. Since they can fly, bats can viruses farther and more easily than other animals.
wild animals carry many diseases, it doesn't mean that we should consider them as human's enemies. Each kind of animal plays a role in the ecosystem(生态系统) and all of them are important. The we should learn from virus outbreaks(爆发) is to respect and animals and to live in peace with them, of hunting, killing, or eating them. Only in this way can we create a better world for our next generation.
