什么使我们生病？
What Makes Us Ill? Have you ever been ill? When you are ill, you don't want to study and you have to stay in bed, feeling very sad. What makes us ill? They are called germs. Germs are everywhere. They are very small and there could be hundreds of them on a very small thing, however, you can’t find them without a microscope. Germs are always found in dirty water. So you shouldn't drink dirty water, or you might fall ill. If you cut your finger, the dust in the air will get into the cut. Some of the germs on the dust will get into your finger. Your finger will then become big and red, and you will feel a lot of pain.
什么使我们生病？ 你生过病吗？生病时，你不想学习，还得待在床上，感觉糟透了。 什么使我们生病呢？是细菌。细菌无处不在。它们极其微小，一件很小的东西上有可能生存着几百上千的细菌，但是要在显微镜下你才能看到它们。 脏水里总是生存着细菌。所以你不应该喝脏水，要不，你就可能生病。如果你的手指被划破了，空气里的灰尘就会进入这个伤口。依附在灰尘上的一些细菌也进入到你的手指里了。然后，你的手指就会变得又肿又红，你会感到很痛。
