A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely falling below 16℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit. There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.
1. Rainforests can help to adjust the climate because they________.
A. reflect more heat into the atmosphere

Rainforests, it turns out, are not created equal. Take the Amazon rainforest, an area that covers about 7 million square kilometers. But within that huge expanse are all kinds of ecological zones, and some of these zones, says Greg Asner, are a lot more crowded than others.
“Some forests have many species of trees,” he said, “others have few. Many forests are unique from others in terms of their overall species composition…” And all of these different small areas of forest exist within the giant space that is the Amazon Rainforest.
So Asner, using the signature technique called airborne laser-guided imaging spectroscopy, began to map these different zones from the air. “By mapping the traits of tropical forests from above,” he explains, “we are, for the first time, able to understand how forest composition varies geographically.”
The results show up in multicolored maps, with each color representing different kinds of species, different kinds of trees, the different kinds of chemical they are producing and using, and even the amount of biodiversity, the animal and plant species that live within each zone.
Armed with this information, Asner says decision-makers now have “a first-time way to decide whether any given forest geography is protected well enough or not. If not, then new protections can be put in place to save a given forest from destruction.”
Asner says the information is a great way for decision-makers to develop a “cost-benefit ratio type analysis.” Conservation efforts can be expensive, so armed with this information, government leaders can ensure they are making the most of their conservation dollars by focusing on areas that are the most biologically diverse or unique.
The next step, Asner says, is to take his project global, and to put his eyes even higher in the sky, on orbital satellites. “The technique we developed and applied to map Peru is ready to go global.” Asner said. “We want to put the required instrumentation on an Earth-orbiting satellite, to map the planet every month, which will give the best possible view of how the world’s biodiversity is changing, and where to put much needed protections.
1.Unequally-created rainforests refer to the fact ______.
A. how crowded they are
B. where they are located
C. when they came into being
D. what kinds of species they have
2.What can government leaders learn from Asner’s mapping?
A. The cost to conserve forests.
B. The chemicals needing for certain forests.
C. The forest areas needing special protection.
D. The number of animals living in a forest.
3.What is Asner planning to do now?
A. To send a satellite to map the world.
B. To track the change of biodiversity in the world.
C. To develop technology for mapping the globe.
D. To advertise his project around the world.
4.What does the passage mainly talk about?
A. Using eyes in the sky to map biodiversity.
B. Making a map of big forests in the world.
C. Learning about the biodiversity of Amazon forest.
D. Protecting the forest from being destructed.

Death Valley is one of the most famous deserts in the United States, covering a wide area with its alkali sand. Almost 20 percent of this area is well below sea level, and Badwater, a salt water pool, is about 280 feet below sea level and the lowest point in the United States.
Long ago the Panamint Indians called this place “Tomesha”— the land of fire. Death Valley’s present name dates back to 1849, when a group of miners coming across from Nevada became lost in its unpleasantness and hugeness and their adventure turned out to be a sad story. Today Death Valley has been declared a National Monument(纪念碑) and is crossed by several well-marked roads where good services can be found easily. Luckily the change created by human settlement has hardly ruined the special beauty of this place.
Here nature created a lot of surprising, almost like the sights on the moon, ever-changing as the frequent wind moves the sand about, showing the most unusual colors. One of the most astonishing and variable parts of Death Valley is the Devil’ s Golf Course, where it seems hard for one to tell reality from terrible dreams. Sand sculptures(沙雕) stand on a frightening ground, as evening shadows move and lengthen.
1.______ is the lowest place in the desert.
A. Tomesha B. Death Valley
C. Nevada D. Badwater
2.The name of the valley comes from _______.
A. an Indian name B. the death of the miners
C. the local people D. a National Movement
3.From the passage we can learn that _______.
A. no one had ever known the desert before the miners
B. it’s still not easy to travel across the desert
C. people can find gas-stations, cafes and hotels in the desert
D. people have changed the natural sight of the desert
4.Devil Golf Course is famous for _______.
A. the frequent wind B. the colors of the sand
C. dream-like sights D. the sand sculptures
5.From the passage we can see that the writer _______ the Death Valley.

In the 1990s, when an area of Brazilian rainforest the size of Belgium was cut down every year, Brazil was the world’s environmental villain (反派角色) and the Amazonian jungles the image of everything that was going wrong in green places. Now, the Amazon ought to be the image of what is going right. Government figures show that deforestation fell by 70% in the Brazilian Amazon region during the past decade. If clearances had continued at their rate in 2005, an extra 3.2 billion tonnes of carbon dioxide would have been put into the atmosphere. That is an amount equal to a year’s emissions from the European Union. Arguably, then, Brazil is now the world leader in addressing climate change.
But how did it break the vicious cycle (恶性循环)? The answer, according to a paper is that there was no silver bullet but instead a three-stage process in which bans, better governance in frontier areas and consumer pressure on companies worked.
The first stage ran from the mid-1990s to 2004. This was when the government put its efforts into bans and restrictions. The Brazilian Forest Code said that, on every farm in the Amazon, 80% of the land had to be set aside as a forest reserve. As the study observes, this share was so high that the code could not be followed --- or enforced. This was the period of the worst deforestation. Soybean prices were high and there were a vast expansion of soybean farming on the south-eastern border of the rainforest.
During the second stage, which ran from 2005 to 2009, the government tried to boost its ability to police the Amazon. Brazil’s president made stopping deforestation a priority, which resulted in better co-operation between different bits of the government. The area in which farming was banned was increased from a sixth to nearly half of the forest.
The third stage, which began in 2009, was a test of whether a system of restrictions could survive as soybean expansion continued. The government shifted its focus from farms to counties (each state has scores of these). Farmers in the 36 counties with the worst deforestation rates were banned from getting cheap credit until those rates fell.
By any standards, Brazil’s Amazon policy has been a success, made the more remarkable because it relied on restrictions rather than rewards, which might have been expected to have worked better. Over the period of the study, Brazil also turned itself into a farming superpower, so the country has shown it is possible to get a huge increase in food output without destroying the forest. Moreover, the policies so far have been successful among commercial farms who care about the law and respond to market pressures. Most remaining deforestation is by small holders who care rather less about these things, so the government faces the problem of persuading them to change their ways, too. Deforestation has been slowed, but not yet stopped.
1.Brazil is considered to play a leading role in dealing with climate change because ________.
A.it has rainforest as large as Belgium.
B.it has cut down too much rainforest.
C.it has taken action to reduce deforestation.
D.it sent 3.2 billion tons of carbon dioxide into the air.
2.The underlined phrase “silver bullet” in Paragraph 2 most probably refers to _______.
A.a powerful weapon. B.an effective solution.
C.an intelligent device. D.a golden opportunity.
3.What can we infer from the last paragraph?
A.Brazil has successfully eliminated deforestation.
B.All the farmers care much about forest protection.
C.Small farm holders are a headache for the Brazilian government.
D.Both the food output and the forest in Brazil have greatly increased.
4.What can be the best title of the passage?
A.Cutting Down on Cutting Down. B.Brazil, the World Leader in Farming.
C.Restrictions Outperforming Rewards. D.Former Awareness Working Wonders.
