3、on earth, containing over 30 million species of plants and animals. That's half of the Earth's wild animal species and at least two­thirds of its plant species! Rainforests store water. In fact, it is believed that the Amazonian forests alone store over half of the Earth's rainwater

4、! Rainforest trees draw water from the forest floor and release it back into the atmosphere. Without rainforests continually recycling huge quantities of water, feeding the rivers, lakes and irrigation systems, droughts would become more common.Do you know that we also depend on trees to cleanse (净化

5、) our atmosphere? They absorb the carbon dioxide that we breathe out, and provide the oxygen we need. However, when rainforest trees are burnt, they release carbon dioxide, which pollutes the atmosphere and contributes to global warming.Surprisingly, soil in the rainforest is very poor in nutrients.

6、 This is because the nutrients are stored in the huge numbers of trees and plants rather than in the soil. Tree roots bind the soil together, while the canopy (树荫) protects the soil from heavy rain. When a tree dies and its trunk falls to the forest floor, it breaks down and the nutrients it contain

7、s are recycled. However, if trees are removed from the forest, the nutrients are removed with it. What's worse, the unprotected soil is then simply washed away by heavy rain, causing floods in lowland rivers while leaving upland rivers dry.Many local people have been living in harmony with the r

8、ainforest for thousands of years, depending on it for their food, shelter and medicines. When oil and logging companies come to remove vast areas of forest, they bring diseases which people there have no resistance to and threaten their survival. Often they are also forced to move away from their ho

9、mes to unfamiliar places, sometimes even being killed in the process.21.What can we learn about rainforests from Paragraph 2?A.They are impossible to recover once damaged.B.They are too old and complex to evolve themselves.C.They have fewer wild animal species than plant species.D.They're import

10、ant homes to wild animal and plant species.22.Why does the author mention the poor soil in the rainforest?A.To stress the importance of trees to soil.B.To encourage improvement of soil there.C.To explain a very interesting phenomenon.D.To raise people's awareness of protecting soil.23.What can w

11、e learn from the passage?A.We can burn rainforests to make the land richer.B.We should do our best to prevent global warming.C.We should protect rainforests instead of destroying them.D.We can depend on many things to cleanse our atmosphere.BA new study has identified pollution as the world's No

12、.1 killer. Study organizers say pollution is responsible for more premature deaths than war, terrorism, natural disasters, smoking and disease. By saying premature death, the researchers mean dying before the average age of death within a population group. Many of these deaths can be prevented.A rep

13、ort on the study was published in the medical journal The Lancet. The researchers looked at pollution levels, both inside enclosed (封闭的) buildings and in the world around us. They concluded that pollution killed about 9 million people in 2015. That would represent one of every six deaths worldwide.K

14、arti Sandilya helped to prepare the report. He said, “Pollution damages fundamental human rights, such as the right to life, health, well­being, safe work as well as the protection of children and the most vulnerable (易受伤害的).”The report said the large majority of pollution­related deaths t

15、ake place in developing countries. The researchers say leaders in those countries are more concerned about building their economics and public services than environmental controls. Some of the most affected countries are Bangladesh, China, Haiti, India, Pakistan, North Korea and South Sudan.But Rich

16、ard Fuller, another writer of the report, said pollution is tied to slow economic development in both rich and poor nations. He said, “Finance ministers still hold firmly that you have to let industry pollution or else you won't develop. What people don't realize is that people who are sick

17、or dead cannot contribute to the economy. They need to be looked after.”The report said that 9 million premature deaths a year is only a conservative figure. It said the actual number is likely to be much higher.A separate study by the World Bank said reducing pollution must be a top goal. It said t

18、hat settling this problem would lead to approaches to other dangers, including poor nutrition (营养) and rising temperatures on the Earth's surface.24.Which is mainly to blame for pollution according to the report?A.Poor countries.B.Rich countries.C.Common people.D.The government.25.What does the

19、first research find?A.Pollution is serious in both rich and poor countries.B.Premature deaths cannot be prevented worldwide.C.Pollution has something to do with slow development.D.Pollution has caused more premature deaths than expected.26.Why is “A separate study” mentioned in the last paragraph?A.

20、To provide more information about pollution.B.To make the findings of the first study more convincing.C.To offer more specific approaches to deal with pollution.D.To emphasize the relationship between pollution and global warming.27.Which of the following can be best used as the title of the passage

21、?A.Pollution Is the World's Number One Killer.B.Pollution Is Becoming Increasingly Serious.C.What Makes Pollution Increasingly Serious.D.How People Deal with Pollution Worldwide.CScientists are trying to save Puerto Ricos endangered Amazon parrots after Hurricane Maria destroyed the birds habita

22、ts and food sources(来源).El Yunque is a large national forest on the eastern part of Puerto Rico. Just two of the 56 wild parrots that once lived there survived Maria, the Category-4 storm that struck Puerto Rico in September 2017. Scientists report other forests have seen great drops in parrot popul

23、ations as well.In the 1800s, there were more than a million of the bright green parrots living in the wild in Puerto Rico. By the 1970s, the number was down to just 13 birds after years of forest clearing.A special program was started in 1972 to help increase the parrot population, which led to the

24、creation of three breeding(繁殖) centers. Just weeks before Hurricane Maria hit, scientists counted 56 wild parrots at El Yunque. That was the highest number in the program's history. Scientists say that even though several parrots have been born in captivity(笼养) and in the wild since Maria, the s

25、pecies is still in danger.The Puerto Rican Amazon is the islands only remaining native parrot. More than 460 of the birds are kept inside the breeding centers at El Yunque and the Rio Abajo forest. Scientists have not released(释放) any of the birds since Hurricane Maria. A third breeding center, in a

26、 forest in the western area of Maricao, has not been in operation since the storm.Scientists are considering whether to catch some of the remaining wild parrots and put them in the same cage as the birds that are set to be released. This way, the captive birds can learn from the wild birds how to su

27、rvive in the forests. Another consideration is to release some captive parrots in Maricao, which was not as heavily damaged by Maria.28. Why has the parrot population greatly decreased in the past 200 years?A. Because of Hurricane Maria.B. Because of too much hunting.C. Because of the loss of forest

Hurricane Maria Reduced the Number of Amazon Parrots.DAntareticas ice-white environment is going green and facing other unexpected threats. Scientists say that as temperatures go up i

31、n the polar region, invading (入侵) plants and insects, including the flies, cause a major conservation threat.More and more of these invaders, in the form of larvae (幼虫) or seeds, are surviving in coastal areas around the South Pole, where the temperature has risen by more than 3 over the past three

32、decades. Glaciers have retreated, exposing more land which has been occupied by mosses that have been found to be growing more quickly and thickly than ever before providing potential green homes for invaders.“The common house flies are a perfect example of the problem the Antarctic now faces from i

33、nvading species,” said Dominic Hodgson of the British Antarctic Survey. “It comes in on ships, where it exists in kitchens and then at bases on the continent. It now has an increasing chance of surviving in the Antarctic as it warms up, and that is a worry. Insects like the house flies carry bacteri

Together with its native mosses, these are now coming under increased threat from three major sources: visiting scientists, increasing numbers of tourists and global warming. However, it is gl

35、obal warming that is the main driver of the greening of Antarctica.In 2015, more than 38,000 tourists visited Antarctica. “These tourists are often very careful about not leaving waste or having mud. But they could carry seeds or larvae on their boots when they set foot on the Antarctic,” said Hodgs

36、on.More and more invasive insects and plants have been found on the Antarctic and have required removal. “the insects and plants that are native to Antarctica have survived these for thousands of years,” said Hodgson. “We have got to act now if we want to save the environment.”32.
