11、. 能力提升练 .阅读理解 A In the past 50 years, the amount of water in the open ocean with zero oxygen has gone up more than fourfold. In coastal water bodies,including river mouths and seas, low-oxygen sites have increased more than tenfold since 1950. Scientists expect oxygen to continue dropping even outsi

12、de these zones as the Earth warms. “Oxygen is fundamental to life in the ocean,” said Denise Breitburg, a marine ecologist at the Smithsonian Environmental Research Center. “The decline in ocean oxygen ranks among the most serious effects of human activities on the Earths environment. Actually, its

13、a great loss to all the support services that rely on recreation and tourism, including hotels, restaurants, taxi drivers and everything else. The reverberations(严重影响) of unhealthy ecosystems in the ocean can be extensive.” In areas traditionally called “dead zones”, like those in Chesapeake Bay and

14、 the Gulf of Mexico,oxygen plummets(大幅下跌) to so low levels that many animals die. As fish avoid these zones,their habitats become smaller and theyre easier to be attacked or caught. But the problem goes far beyond “dead zones”. Even smaller oxygen decline can prevent growth in animals, hinder reprod

15、uction and lead to disease or even death. It also can cause the release of dangerous chemicals such as nitrous oxide, a greenhouse gas up to 300 times more powerful than carbon dioxide. While some animals can boom in “dead zones”,overall biodiversity falls. Climate change is the key criminal in the

16、open ocean. Warming surface waters make it harder for oxygen to reach the inside of the ocean. Furthermore, as the ocean as a whole gets warmer, it holds less oxygen. In coastal waters, too much nutrient pollution from land creates algal blooms, which run out of oxygen as they die and break down. Pe

17、oples livelihoods are also on the line, the scientists reported, especially in developing nations. Smaller fisheries(渔场)may be unable to relocate when low oxygen destroys their harvests or forces fish to move elsewhere. So we humans have to carry on a war now and win the war. 1.What does the first p

18、aragraph mainly talk about? A.The ocean has been losing its oxygen. B.The amount of sea water is increasing. C.The coastal water bodies are dangerous. D.The Earth becomes warmer and warmer. 2.What can we infer from Denise Breitburgs words? A.Different oceans have different levels of oxygen. B.The de

19、cline in ocean oxygen has great influences. C.The future of tourism relies on the levels of ocean oxygen. D.The decrease in ocean oxygen is the most serious environment problem. 3.How does the “dead zone” affect sea animals? A.It offers more food. B.It forms dangerous gas. C.It reduces their living

20、areas. D.It produces more carbon dioxide. 4.How can we win the war according to the text? A.By closing smaller fisheries. B.By controlling humans bad activities. C.By improving peoples living standards. D.By stopping nutrients entering the ocean. B On the day the tornado(龙卷风) hit, there was no sign

21、that fierce weather was on its waythe sky was blue and the sun had been out.The first warning my husband, Jimmy, 67, and I, 65, got came around 9 p.m., from some text on the TV Jimmy was watching. He ran upstairs to find me in our third-floor bedroom, and we changed the channel from the national tel

22、evision to our local Pensacola station, Florida. Soon the tornado was on top of us. It was the loudest thing I had ever heard. The bones of the house shook. The power broke down. The wind began to roar(咆哮) through the house, most likely through blown-out windows and the door to our garage. Everythin

23、g was moving. And the back wall of the house came off and flew into the darkness outside. We had three flights of steps to get to the storeroom down there, the relative safety of the first floor. I didnt know how or if we would make it down the steps. It felt as if there were no floor underneath me

24、as the wind lifted me off my feet. As we finally reached the last flight of steps, our front door blew out. Suddenly, a three-foot-long tree branch flew over our heads, missing us by inches. By the time I reached the storeroom, the tornado had been over us for about a minute. Jimmy pushed me down to

25、 the storeroom floor, but he couldnt get inside himself because of the wind. I held Jimmys arm as the tornado blew the door open. My knees were full of glass, but I felt no pain. If I had let go, Jimmy would have flown right out the back of the house. All of a sudden, Jimmy lifted off his feet. I th

26、ought he was gone. And then everything stopped. He landed on his feet. In those first quiet moments, I couldnt believe it was over. Our neighbor said the storm lasted four minutes. In that time, four of the twelve town houses in our unit were completely destroyed. Amazingly, none of us were seriousl

27、y injured. 5.Where did the couple learn about the coming fierce weather? A.From the dark sky. B.From the national station. C.From the local news report. D.From the text sent by their neighbors. 6.What can we infer from Paragraph 2 about the couple? A.They were hit by a tree branch. B.They tried to g

28、et out of the house. C.Their garage was blown to pieces. D.Their house was badly destroyed. 7.What do we know about Jimmy when the author reached the storeroom? A.He was in great danger. B.He flew out of the house. C.He was seriously injured. D.He got inside the storeroom. .七选五 Urban Wildlife Cities

29、 are diverse ecosystems. In addition to visitors, a large number of species share our urban areas. As our cities spread, we need to think about what it is like for other species to have human neighbors. Cities are built for humans. 1 For example, most city parks are kept neat and tidy so that humans

30、 will find them beautiful. But when we cut grass or plants, we destroy natural habitats,which leads to the imbalance of ecology. 2 When a bridge in Austin, Texas was repaired, engineers added small gaps running along the length of its bottom. This made a good home for bats, and soon the bridge was h

31、ome to thousands of bats. 3 Now, they have come to value their winged neighbors. The bats become a tourist attraction, and they eat lots of bugs every night. There are also structures built with the aim of bringing wildlife into the city. The Beijing Olympic Forest Park is a good example. The park u

32、sed native plants and created open, and natural spaces for wildlife. The result is a zone in Beijing with over 160 species of birds. In many ways, the park is the opposite of a zoo. 4 If we learn to share our space, we can become better neighbors to the wildlife around us. 5 Our own future will be e

33、ndangered too. A.They are built to protect birds. B.Our actions sometimes help other species. C.If we do not, more species will become extinct. D.They do not always provide suitable habitats for wildlife. E.Instead of being kept in cages, wildlife can move more freely. F.At first, people were afraid

34、 of the bats and tried to get rid of them. G.They would sit on it and their droppings would fall into the water. 1. 2. 3. 4. 5. 答案全解全析 UNIT 5 HUMANS AND NATURE Part 4 LESSON 3 RACE TO THE POLE 基础过关练 .1.bravery 2.honesty 3.cheerful 4.base 5.ambition 6.tent 7.captain 8.polar 9.skis 10.boots 11.contine
