【題目】 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 (英畝) 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 this 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 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.

Myers also talked about the big disaster about the rain forest fires in the Amazon—the lungs of the Earth. The Amazon forests produce 20% of the world’s oxygen (氧氣). Even if it’s just a small part of the rain forests that are destroyed, it’s a great loss to the whole world. That means, once an area of land burns, it doesn’t regrow as forest. Now Myers’ students know that we should try to protect the rain forests, or the last drop of water on the earth will be our tears.

【1】How much did Myers’ students pay for the rain forest they bought?

A.$25B.$75C.$80D.$2000

【2】What did Myers and his students do at the beginning of the trip?

A.They went into the rain forest.B.They bought acres of rain forest.

C.They took a boat ride down a river.D.They visited Costa Rica’s active volcano.

【3】The word “Destruction” in paragraph 2 probably means “Being __________”

A.discoveredB.developedC.describedD.destroyed

【4】What will cause “The last drop of water on the earth will be our tears”?

A.Killing some pigs and beef for meat.

B.Cutting down a large amount of trees in the forest.

C.Buying some fruits grown in the rain forest.

D.Traveling in the rain forest.

【5】The passage mainly shows that Myers and his students __________.

A.did something to protect rain forest

B.wanted to buy the rain forest in Costa Rica

C.were interested in the culture of Costa Rica

D.went to the rain forest for various fun activities.
