Flies(苍蝇) usually live in the rubbish(垃圾). Let’s look at a fly, and see where it flies. First it flies out of the house; second, it stands on some dirty things in the street; and third, it flies back to the house and walks over your food.

When a fly walks on the dirty things in the street, its feet get some germs(细菌) from them. When the fly walks on your food with its dirty feet, it leaves the germs on your food. What can you learn from this?

First, we learn that we mustn’t throw(扔) dirty things in the street or on the ground(地面) near our house.

Second, we learn that all food must be covered(被遮盖) to keep the food clean.

Third, we learn that flies often carry germs and we must kill(杀死) them when we see them.
