并在答题卡上将该选项涂黑．AOne reaction to all the concern about tropical deforestation(砍伐森林) is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.Take rubber（橡胶） for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial（商业的）rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.Many scientists strongly believe that deforestation contributes to the greenhouse effect—or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide intooxygen.Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realize the severe effects of tropical deforestation, it will be 20 years too late.Can tropical deforestation affect our everyday lives? Now, you should have got the answer.1. The underlined word "synthetics" probably means a kind of __________.A. natural rubberB. tropical grassC. man-made materialD. tropical tree2. In the last paragraph the author tries to _________.A. tell people how to avoid the tropical deforestationB. show us how important it is to protect the tropical forestsC. persuade people to buy something syntheticD. let people realize the good effect of tropical deforestation3. The author's attitude towards the tropical deforestation is __________.A. puzzlingB. coldC. supportingD. opposedBAs a boy, Charles Robert Darwin collected anything that caught his interest: insects, coins and interesting stones. He was not very clever, but Darwin was good at doing the thingsthat interested him.His father was a doctor, so Darwin was sent to Edinburgh to study medicine, and was planned to follow a medical career. But Charles found the lectures boring. Then his father sent him to Cambridge University to study to be a priest. While at Cambridge, Darwin’s interest in zoology and geography grew. Later he got a letter from Robert FitzRoy who was planning to make a voyage around the world on a ship, the Beagle. He wanted a naturalist to join the ship, and Darwin was recommended(推荐). That voyage was the start of Darwin’s great life.As the Beagle sailed around the world, Darwin began to wonder how life had developed on earth. He began to observe everything. After he was home, he set to work, getting his collection in order. His first great work The Zoology of the Beagle was well received, but he was slow to make public his ideas on the origin of life.Later Darwin and Wallace, another naturalist who had the same opinions as Darwin, produced a paper together. Darwin’s great book, On the Origin of Species by Means of Natural Selection (《物种起源》) appeared. It attracted a storm. People thought that Darwin was saying they were descended from monkeys. What a shameful idea! Although most scientists agreed that Darwin was right, the Church was still so strong that Darwin never received any honors for his work.Afterwards, he published another great work, The Descent of Man. His health grew worse, but he still worked. “When I have to give up observation, I shall die,” he said. He was stillworking on 17, April, 1882. He was dead two days later.1.

Darwin’s father sent him to Edinburgh to _____.A. make him like natural historyB. make him become a doctorC. let him change his hobbiesD. have him give up his collection3. According to the passage, Charles Darwin’s whole life was changed by _____.A. his study at Cambridge UniversityB. his collection of coinsC. the naturalists at CambridgeD. the voyage of the Beagle4. The underlined part “they were descended from monkeys”probably means “_____”.A. they gave monkeys lifeB. they were different from monkeysC. they were developed from monkeysD. they had to live with monkeysCSo great is our passion for doing things for ourselves thatwe are being increasingly less dependent on specialized labour.No one can plead ignorance（对。
