　　In the natural world, animals and humans are not usually friends, but there are a few interesting examples where they can work together．In Africa, the honeyguide bird works with humans to find food．The bird likes to eat the grubs－a kind of insect that lives inside a beehive(蜂窝)．It knows how to find beehives but it can't open them and get the grubs．People like to eat honey(蜂蜜), but they aren't good at finding beehives, so the bird and the people help each other．The bird flies to a beehive and people follow it．When the people open the beehive and take the honey, they give the grubs to the bird．

　　In Laguna in the south of Brazil(巴西), fishermen and dolphins work as a team．The ocean isn't very clean, so the fishermen can't see the fish．However, dolphins can find them easily by using sounds．When the dolphins find a large group of fish, they make a noise to tell the fishermen．Then the dolphins push the fish towards the beach．The fishermen wait in the water near the beach and catch a lot of fish in their nets．The fishermen's nets make it easier for the dolphins to catch fish too．In Laguna, fishermen and dolphins have been working together for many years．The fishermen teach their children how to work with the do phins．The dolphins must be happy to help because they teach their babies how to work with the humans!

　　Why do people cry? Scientists say the body produces tears because they need them．One kind of tears is for the eye, the other is for the heart．They both work as cleaners．If something else like dust(灰尘)gets into your eye, tears also come into the eye to clean it out．If you are hurt by something, your strong feelings produce some poisonous chemicals(毒素)in your body, and at the same time, tears come out with them．If these poisonous chemicals are not cleaned out of your body as soon as possible, they will do harm to the heart sooner or later．

　　In the United States men have heart problems more often than women do．Doctors say heart problems have something to do with the pressures(压力)of living and working now．Perhaps men suffer more from these illnesses because they do not cry enough．They need to cry more．
