6、reat chance!1. How long does the camp last every year?A. One week.B. One month.C. Six weeks.D. Five months.2. What can a child learn from the camp?A. How to deal with people.B. How to choose a strong team.C. How to avoid physical problems.D. How to stay interested in something.3. What is the purpose

7、 of the text?A. To describe the history of the camp.B. To compare the camp with other activities.C. To tell parents about the benefits of outdoor activities.D. To encourage parents to send their children to the camp.B As global temperatures rise, trees around the world are experiencing longer growin

8、g seasons, sometimes as much as three extra weeks a year. All that time helps trees grow faster. For the past 100 years, trees have been experiencing fast growth in mild areas from Maryland to Finland, to Central Europe, where the growth rate of some trees has even sped up by nearly 77% since 1870.

9、Supposing wood were just as strong today, those gains would mean more wood for building, burning, and storing carbon captured from the atmosphere. But is wood reallyas dense(茂密的) as it used to be? Hans Pretzsch, a forest scientist at the Technical University of Munich in Germany, and his colleagues

10、wanted to find an answer. They carried out a study of the forests of Central Europe. They started with small pieces of experimental land in southern Germany, some of which have been continuously monitored since 1870. Pretzsch and his team took core samples (样品) from the trees which included Norway s

11、pruce, sessile oak, European beech, and Scots pine and analyzed the tree rings using a high-frequency probe. They found that in all four species, wood density had decreased by 8% to 12%. We expected a trend of the wood density like this, but not such a strong and significant decrease, Pretzsch says.

12、 Increasing temperatures, and the faster growth they spur, probably account for some of the drop. Another factor, Pretzsch says, is more nitrogen in the soil from agricultural fertilizer and vehicle exhaust. Previous studies have linked increased fertilizer use to decreased wood density. Above all,

13、the study suggests that the higher temperatures combined with pollution from car exhaust and farms are making wood weaker, resulting in trees that break more easily and wood that is less durable. I am getting worried, says Richard Houghton, an ecologist at the Woods Hole Research Center in Falmouth,

14、 Massachusetts, who was not part of the new study. As the density of the samples dropped, so did their carbon content. That means forests may suffer more damage from storms and may be less efficient at soaking up(吸收) the greenhouse gas carbon dioxide (CO2) than scientists think, Houghton says.1.Para

16、ton mean?A.Great loss might be caused.B.Storm damage can be prevented.C.The size of forests might be increased.D.Less greenhouse gases can be sent out.4.What is the best title for the passage?A.We only have one earthB.Trees our best friendsC.The influence of climate changeD.Trees are growing faster,

17、 but weakerC California has lost half its big trees since the 1930s,according to a study to be published Tuesday and climate change seems to be a major factor(因素). The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the

18、new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 per

19、cent. Many factors contributed to the decline, said Patrick McIntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big t

20、rees for resources(资源). But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, McIntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development. The loss of

21、big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature

22、, dampness of soil, and the timing of snowmelt(融雪). Since the 1930s, McIntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during

23、the dry season.1. What is the second paragraph mainly about?A. The seriousness of big-tree loss in California.B. The increasing variety of California big trees.C. The distribution of big trees in California forests.D. The influence of farming on big trees in California.2. Which of the following is w

24、ell-intentioned but may be bad for big trees?A. Ecological studies of forests.B. Banning woodcutting.C. Limiting housing development.D. Fire control measures.3. What is a major cause of the water shortage according to McIntyre?A. Inadequate snowmelt.B. A longer dry season.C. A warmer climate.D. Damp

25、ness of the air.4. What can be a suitable title for the text?A. Californias Forests: Where Have All the Big Trees Gone?B. Cutting of Big Trees to Be Prohibited in California SoonC. Why Are the Big Trees Important to California Forests?D. Patrick McIntyre: Grow More Big Trees in CaliforniaD I just go

26、t back from an extraordinary trip to the Arctic North of Norway, and I felt excited and alarmed at the same time. I knew before I went there that the Arctic was the centre of global warming, but seeing the changes first-hand is haunting. There is one scene I will never forget. It came just a few day

27、s into the trip. I was on board the ship National Geographic Endeavor, and was halfway between the Arctic Circle and the North Pole. I had never been so far north or in a more remote place on Earth. But I was in good company. The Aspen Institute had invited 100 politicians, scientists, businessmen,

28、religious and labor leaders to see the impacts of global warming with their own eyes. One day, we had the electrifying experience of watching polar bears play on the ice. We tend to think of the Arctic as an expanse of white, but it isnt. The sea is dark. The pack ice comes in deep, beguiling blues.

29、 Polar bears are yellowish. And all of these colors pop against a steely grey sky. On one ice sheet, we saw two polar bears, their furs covered with red from a just completed dinner. One was moving in and out of the water; the other was busy eating the seal. Off to the side, a smaller bear peaked ov

30、er the ice with its black snout(鼻子), waiting for the big ones to get off the kill so it could go over to the remains. All three bears seemed powerful and vibrant. But later, we sailed passing an island where a polar bear sat on the shore, stranded because the sea ice had receded so far from shore. T

31、his bear will not eat until next winterit simply cannot hunt without the ice. Polar bears can survive for long stretches without eating, but seeing that lone bear brought home just how dependent these iconic creatures are on sea ice. Scandinavians, after all, call them the Ice Bear. I have read enou

32、gh climate reports to know that with summer sea ice disappearing at alarming rates, the bear I saw stranded that day is one of many. Now I have a permanent memory of what a hungry, stranded bear looks like.1. What does the underlined word haunting most probably mean?A. Surprising.B. Exciting.C. Fasc

33、inating.D. Unforgettable.2. From the second paragraph we can infer that the people on the journey _.A. were experts at global warmingB. came from all walks of lifeC. had been to the Arctic beforeD. were mostly adventurers3. What is these peoples aim to Arctic?A. To do some research on global warming

34、.B. To witness the influence of global warming.C. To experience the beautiful sight of global warming.D. To see the various animals face to face.4. What did the two bears they saw look like?A. Their furs were red in colour.B. There was blood on their furs.C. They were very hungry.D. They seemed blac

Not all are right for everybody. But applying just a few of them could make a

36、 difference. Move closer to work. Transportation is one of the leading sources of greenhouse gas emissions._ One way to dramatically cut transportation fuel needs is to move closer to work, use mass transportation, or switch to walking, cycling or some other modes of transport that does not require

37、anything other than human energy. Consume less._ Whether by quitting an automobile or employing a reusable grocery sack, cutting back on consumption results in fewer fossil fuels being burned to extract, produce and ship products around the globe. _ A potentially simpler and even bigger effect can b

38、e produced by doing more with less. Citizens of many developed countries are energy-wasters, whether by speeding in a gas-wasting vehicle or leaving the lights on when not in a room. Similarly, employing more efficient refrigerators, air conditioners and other appliances can cut electricity bills._

39、You can turn the lights or your computers off when you leave the office. Stop cutting down trees. When purchasing wood products, such as furniture or flooring, buy used goods or, failing that, wood proved officially to have been sustainably harvested. The Amazon rainforest and other forests are more
