Mike Myers is a teacher at Chauncey Rose High School in Terre Haute, Indiana. Last year, he taught his students about the world’s rain forests. They learned that rain forests are important because the plants and animals of the rain forest give us food, wood, and medicine.

Destruction of the world’s rain forests is a serious problem. Unluckily, rain forests are disappearing at a rate of 80 acres per minute! As part of a class project, Myers’ students bought three acres of rain forest in Central America. They paid $25 per acre. The students hope that the land they bought will be protected and not destroyed. The students became so interested in rain forests that they decided to get a closer look at a real rain forest.

So last June, Myers and four of his students took a boat ride down a river. They saw alligators and crocodiles. In the middle of the week, a guide took Myers and his students into the rain forest. “The monkeys were not happy that we were in their forest. They broke small branches off the trees and threw them at us,” one of the students said, “It was a great learning experience for all of us,” said Myers.

Each student chose something specific about Costa Rica to study involving the plants, animals, food, and culture. During the last few days the group had time to do fun activities. They went whitewater rafting and horseback riding, and visited Costa Rica’s active volcano.

Myers hopes to make the trip every year with a different group of kids.

Bats(蝙蝠)are unusual animals. Even though they fly, they are not birds.Bats are the only mammals that fly. A mammal is an animal that has hair and feeds its babies with its own milk.Mother bats have babies each spring. Baby bats hang onto their mothers until they learn to fly by themselves.

Bats can be many different colors. Most are brown, but some are black, orange or even green.

Even though many people do not like bats,bats don’t usually cause people trouble. Only vampire bats(吸血蝙蝠)are very dangerous. Bats in the United States help people.Every year they eat millions of bad insects!

Bats sleep all day because they cannot see well in the bright sunlight. They hang upside down in dark places. As soon as darkness begins to fall,bats wake up.They fly around easily and quickly at night. Some bats fly at night,while others fly only in the evening or the early morning.

Bats make sounds that help them fly,since they cannot see well. People cannot hear these sounds. When bats make sounds, the sounds hit objects in front of them and go back at them.

Most bats eat mosquitoes(蚊子) and moths(飞蛾),but there are some bats that will catch fish swimming in water and eat them.Still other kinds of bats eat birds or mice.Bats that live in very hot areas eat only some parts of flowers.
