Unit 4 Global warmingⅠ.阅读理解AWildfires and heat waves have been troubling the states of California and Arizona this year. Since 2010, about 6.4 million acres have been burned on average per year. Recent studies have stated that global warming is the cause of these wildfires and higher temperatures, and that the incidence of these natural disasters is likely to increase.As temperatures increase, wildfires become more common. As this cycle progresses, climate change and wildfires both increase frequently and seriously. Forest fires are also developing at higher frequencies as a result of global warming. Firefighters use techniques like back-burning to help prevent further spread of these fires, but these measures are not always effective.Some factors that promote wildfires, such as drought and insect outbreaks, have been linked to global warming as well. Insects that kill trees and other plants make the remains more sensitive to fires, as the plant matter dries out and can more easily be burned. Higher temperatures that result from climate change cause more water to evaporate(蒸发)from reservoirs and lakes, which can lead to drought.With global warming causing higher temperatures, the wildfire seasons of affected areas lengthen. This occurs because summer heat begins to build earlier in the year, and the cooling fall season is delayed. For forests in the southwest United States, the conclusion of snow’s melting indicates the time when fires are able to start. Climate change has caused the melting of snow to occur earlier than it did 50 years ago by about one to four weeks.The global warming trend has hit Southern California extremely hard, and the months of January through April have been hotter this year than they have been for any others in recorded history. This has also caused a drought which has been severe or worse for the entire state. Last year, drought affected only 46 percent of California.With the results from these recent studies, global warming has been linked to an environment that promotes wildfires, by creating higher temperatures and causing drought. California’s wildfire season is just starting, and the damages are likely to be worse as the season continues.1. What does the author intend to tell in the passage?A. Global warming causes high temperatures and wildfires.B. Forest fires have been bringing serious threat to the earth.C. High temperatures make water disappear at a high speed.D. California and Arizona are faced with the extreme weather.2. Why are insects connected with wildfire?A. Because tons of insects exist in the forests.B. Because drought drives insets into the forests.C. Because insects leave the trees dead and dry.D. Because the bodies of insects can burn easily.3. We can conclude from the passage that .A. it is impossible to prevent wildfire from happeningB. the southern states in the USA will see the longest summerC. it is necessary to raise awareness of fire preventionD. California has done nothing to fight wildfiresBFred and Bonnie have 21 children. First they had two of their own and they adopted 19 others from countries around the world. They adopted children from many countries, like Japan, India and Vietnam. Each time they made sure they had music, food, pictures, and books of the child's native country so the children would feel good about themselves.Fred and Bonnie had pre-school children running around the house for 26 years without a break! The washer was always going and clothes hung from one end of the room to the other. Everyone helped out with the housework. The family drank ten litres of milk a day.The couple enjoyed their children. They took care of small problems right away so they wouldn't become big problems. Fred says, "If you have trouble with one of your children, don't worry. Worry doesn't help, and in time your child will be all right."When the children were older, Bonnie began travelling to India. She opened three homes for 170 homeless children. She travels there four times a year to bring food, medicine, and used clothing to the needy children.Back home, Bonnie cooks meals for her seven children still living there. The other children keep in touch. When Tran got married,18 brothers and sisters danced at his wedding.They hope their children will find their own way to help others. They want them to be happy, healthy and independent.Fred says, "Let me light my lamp and never wonder if it will take away the darkness."4. What does the word "adopted" underlined in Paragraph 1 mean ?A. raised children with government support.B. looked after children for parents who were busy.C. provided education for children from poor families.D. brought up someone else's child as his parents.5. What did the couple do to make sure that the children felt good about themselves?A. To offer them things from their own country.B. To feed them well.C. To make sure they could play well.D. To handle small problem right away.6. What does Bonnie do after the children grow up?A. She goes abroad to help more children in need.B. She still stays at home to cook for them.C. She set up three homes in Vietnam.D. She often visits her son in India.7. Why do the couple want to live such a life?A. To get extra money from the government.B. To be allowed to build more rooms.C. To have more chances to travel abroad.D. To offer help and to show their love.8. Which of the following is the best title for the article?A. Worry doesn't help.B. A big happy family.C. How to help others.D. Family should keep in touch.Ⅱ.完形填空The back door of the ambulance(救护车)was suddenly shut and the driver ran to the front, jumped into his seat, and started the engine.

Today the scientific community is in almost total agreement that the earth’s climate is changing and that this represents a huge threat to the planet and to us. According to a survey, with only 69% accepting the earth is warming— only 1/4 Americans see global warming as a major threat, public opinion 1 the scientific conclusion.Climate scientists and campaigners have long debated how to better communicate the message to nonexperts so that climate science can be 2 into action. According to Christopher Rapley, the usual tactic(策略) of climate experts to provide the public wit h information isn’t 3 because ＂it does not address key potential causes.＂ We are all exposed to the evidence of climate change on an almost a daily basis. The information is almost 4 .Then what’s wrong? 5 our brains.Daniel Gilbert mentioned our brains’ failure to accurately notice gradual change.

Lertzman has come to the conclusion that the conflict between __11 _ both the planet and our way of life is too painful to bear. ＂When we don’t 12 the pain of that, that’s when we get 13 andcan’t move forward.＂Lertzman refers to this 14 as ＂environmental melancholia(忧郁症),＂ and points out that there’s a lot to be said for providing a means 15 acceptable to talk about.＂Rosemary Randall suggests that climate change is such a(n) 16 subject that it ＂can raise fears and anxieties that people feel have no 17 in polite conversation.＂Lertzman says the community has been slow to realize the value of psychology.

Developed by two doctors in the U.S. Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it’s all butimpossible to find natural substitutes. The only components required, though, are a 5＇ 5＇ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container — perhaps just a drinking cup — to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole.Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won’t have to break down the still every time you need a drink.1. What do we know about the solar still equipment from the first paragraph?A. It’s delicate.B. It’s expensive.C. It’s complex. .D. It’s portable.2.

When a solar still works, drops of water come into the cup from .A. the plastic tubeB. outside the holeC. the open airD. beneath the sheetBIts most keen advocates say that global warming is gradually ruining our parts of our planet. But the effects of the phenomenon might be felt more positively a little closer to home, after scientists claimed that it would make flowers smell sweeter.Some flowers could give out a smell that is nine times more fragrant than they currently produce, according to a report. It says that a temperature increase of between 1℃ and 5℃ will vastly increase the ability of flowers to produce their sweet smells.The study suggests that plants are able to produce more terpenes (萜烯) — the chemicals that give them their smells —in hotter conditions. Despite the environmental risk linked to climate change, the effect on flowers could also help bee populations as the stronger smells make flowers easier to find and pollinate. It also found that the effect could be more significant in cooler countries such as the UK and would have a strong impact on fruit trees.The findings come as the unseasonably warm autumn weather this year has led to reports that plants are being "tricked" into blooming early.Guy Barter described the findings as interesting and said it could have a significant effect on lightly scented flowers. "We think about climate change in terms of rising temperatures and sea levels, but there are more delicate potential effects which we have not thought about," he said.Last year, experts warned the average global temperature had risen by 0.5℃ in 50 years. They predicted temperatures will increase by 3℃ over the next century, causing a rise in sea levels, flooding, disease outbreaks and mass migration of refugees (难民).The researchers looked at a variety of plants. In the paper the researchers said, "The species with the highest increases in emissions were those with the lowestfragrance rates. The increases calculated for floral terpene emissions show that very significant increases in the amount of floral scents will likely occur in a warmer world. The rates of floral terpene emission by the end of the century could increase 0.34—9.1 times because of a 5℃increase in the average maximum temperature during the flowering peak of the season."5. We can infer from the text that in England .A. plants bore more fruits in autumn this yearB. the seasons weren’t in order this whole yearC. the autumn of this year was a little coolerD. plants began to produce flowers early in autumn this year6. What Barter said indicates that .A. every coin has two sidesB. a miss is as good as a mileC. don’t claim to know what you don’t knowD. don’t pu t the cart before the horse7. The last paragraph implies that in hotter conditions .A. plants will have the lowest fragrance ratesB. plants will send more sweeter chemicalsC. plants will suffer the rising temperatureD. plants will finish their flowering peak soon8. Which is the best title of the passage?A. Will plants produce more chemicals in the future?B. Is it easier to find sweeter flowers everywhere?C. Could global warming make flowers smell sweeter?D. Do flowers smell stronger in the cold temperature?Ⅲ. 语法填空Walking down the city streets, you look up and see 1 red telephone box.

专题04 Global warming全球变暖可能会使人类变矮Global warming could make humans shorter, warn scientists who claim to have found evidence that it caused the world’s first horses to shrunk nearly 50 million years ago.In fact, a team from the universities of Florida and Nebraska says it has found a link between the earth heating up and the size of mammals—horses, in this case, the last time the world heated up. The scientists used fossils to follow the evolution of horses from their earliest appearance 56 million years ago.As temperatures went up their size went down, and vice versa; at one point they were as small as a house cat, said Dr. Jonathan Bloch, curator of the Florida museum of natural history, was quoted by the ＂daily mail＂ as saying. The scientists say that the current warming could have the same effect on mammals—and could even make humans smaller.＂Horses started out small, about the size of a small dog like a miniature schnauzer. what’s surprising is that after they first appeared, they then became even smaller and then dramatically increased in size, and that exactly corresponds to the global warming event, followed by cooling. ＂It had been known that mammals were small during that time and that it was warm, but we hadn’t understood that temperature specifically was driving the evolution of body size,＂ Dr. Bloch said in the ＂Science＂ journal.科学家警告说，全球变暖可能会使人类变矮。
