    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.

    O. Henry, a famous American writer of short stories, was born in North Carolina in 1862. O. Henry was a pen name. His real name was William Sydney Porter. When he was a young boy, he did not go to school for long because of being born in a poor family, but he tried to teach himself everything he needed to know.

    When he was about 20 years old, O. Henry went to Texas. There he tried different jobs. He first worked on a newspaper, and then had a job in a bank. But he got himself into some trouble. Some money went missing from the bank. O. Henry was believed to have stolen(偷)it, so he was sent to prison(监狱). During the three years in prison, he learned to write short stories. After he got out of prison, he went to New York and went on writing.

    He wrote mostly about New York and the life of the poor there. People liked his stories, because almost all of them finished with a sudden change. This made the readers surprised.

Although half a century has passed, Shao Guohua never forgot the film ticket his teacher gave him that warmed his heart when he was a boy. Shao entered a primary school in Zigong, SichuanProvince, in 1960. Back then, sports and watching movies were the students' favorite times.

Once, the school organized a trip to the movies for the students, and many of Shao's classmates signed up（报名）for it. But the boy had no money to buy 0. 05-yuan ticket. When his classmates lined up to enter the movie theater, the boy stood alone outside. Then Shao's Chinese teacher Mo Xunru saw him and bought a ticket for him.He can't remember what movie it was, but Shao never stopped being thankful to his teacher.

"Ms. Mo made twenty or thirty yuan a month back then, so a 0.05-yuan ticket may not be a big deal for her. But for me, it moved me deeply," said 63-year-old Shao.

After graduating( 毕 业 ) from primary school, Shao moved to another city along with his parents. In the following years, he tried to find his former（以前的）teachers and classmates, but failed. It wasn't until this year that Shao Guohua visited his teacher, Mo Xunru after 50 years." The reunion ( 重 聚 ) was emotional, " said Shao, who is over sixty himself now. " The 89-year-old Mo did not hear well anymore and seemed to not know me at first sight, but she was still as kind as she used to be." Shao left 1, 000 yuan to his teacher as well as a letter which reads:

"Dear Ms. Mo, wish you good health. Your student: Shao Guohua."
