题目列表(包括答案和解析)
For many years, Hawaii has been a magic name to people who like to travel. People on both sides of the Pacific Ocean, in Japan and in America, dream of seeing these beautiful islands in the middle of the ocean. Their dreams always include at least one scene of a sunset over the ocean. In the tropical(热带的) lands, the sun drops, like a ball of golden fire, into the sea, and it droops so quickly that you can almost see it move. The sun leaves behind a glow that lights the skies and shines in the quiet water.
People often have a quiet, peaceful time ---perfect for a leisurely(悠闲的) walk along the water. This scene is not too different from the dramatic(令人神往的) beauty that greeted the first strangers to these islands centuries ago. They were Polynesian people who came from Tahiti in canoes not much bigger than small boats.
They found the beautiful white sand beaches and the waving palm trees, but there were no giant hotels like the ones we see nowadays. The first people came to Hawaii nearly two thousand years ago, but skyscraper hotels were only built in the last 25 years. Now jet planes make it possible to fly to for a weekend from Tokyo. Wherever the people come from, they really want to see the original beauty of Hawaii. They want to see the lovely beaches and the mountain called Diamond Head which is almost hidden by the tall hotels.

Scientists are trying to make the deserts into good land again. They want to bring water to the deserts， so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming desert all the time. Scientists may not be able to change the desert in time.
Why is more and more land becoming desert？ Scientists think that people make deserts. People are doing bad things to the earth.
Some places on the earth don’t get much rain. But they still don’t become deserts. This is because some green plants are growing there. Small green plants and grass are very important to dry places. Plants don’t let the sun make the earth even drier. Plants do not let the wind blow(吹) the dirt away. When a bit of rain falls， the plants hold the water. Without plants， the land can become desert more easily.
1. Deserts ________.
A. never have any plants or animals in them
B. can all be turned into good land before long
C. are becoming smaller and smaller
D. get very little rain
2. Small green plants are very important to dry places because __________.
A. they don’t let the sun make the earth even drier
B. they don’t let the wind blow the soil away
C. they hold water
D. All of the above.
3. After reading this passage, we learn that __________.
A. plants can keep dry land from becoming desert
B. it is good to get rid of the grass in the deserts
C. all places without much rain will become deserts
D. it is better to grow crops on dry land than to cut them
One reaction to all the concern about tropical deforestation（毁林） 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.
Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial 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 into oxygen.
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 realise 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. natural rubber B. tropical materials
C. man-made material D. commercial rubber
2.According to the passage, which of the following is NOT true?
A. The forests are losing their function in turning carbon dioxide into oxygen.
B. Many of our daily uses are related to the tropical forests.
C. Tropical plants can be used to make industrial products.
D. High carbon dioxide levels will make the earth warmer.
3.The author's attitude towards the tropical deforestation is _________ .
A. puzzling B. cold C. supporting D. opposed
4.Which of the following might be the best title for the passage?
A. Tropical Forests B. The Value of Tropical Forests
C. Tropical Forests and Our Life D. The Greenhouse Effects

Read the following passage. Complete the diagram by using the information from the passage.
Write NO MORE THAN THREE WORDS for each answer.
Most scientists are now certain that global warming is taking place. Gases such as carbon dioxide produced by burning of coal, oil, wood, together with industrial pollution, are creating a warm blanket around the earth. This blanket is trapping heat in the atmosphere and so raising the temperature of the earth.
The evidence for global warming can now be seen in the world’s changing climate statistics. In Europe, eight of the last ten years have seen record high temperature. For northern Europe, this has generally been a change for the better. Gardens can now even grow tropical plants in England, though London may never see a “White Christmas” again. On the other hand, the countries around the Mediterranean Sea, and those south of the Sahara desert are receiving even less rain than before. In sub-Saharan Africa the crops are drying out in the fields and people are dying of starvation. In the Americans, the climate is becoming more extreme—the summers are getting hotter and the storms are becoming more violent. In 1999 the southern United States was struck by a series of destructive hurricanes, while the end of 1999 saw the worst floods ever in Venezuela. Meteorologists expect such trends to continue, and indeed to worsen, if global warming cannot be stopped.
In addition to worrying about rising global temperatures and more extreme weather conditions, scientists are closely monitoring sea levels around the world. These are slowly rising, as the northern and southern polar ice-caps start to melt. This will have serious consequences for low-lying countries near the sea, such as the coral islands in the Pacific, and Bangladesh where the River Ganges already floods the delta（三角洲） every year. Already parts of these places are disappearing under the rising tides.
