1、Lakes, Too, Feel Global WarmingThere\'s no doubt, In the last few decades, the average temperature on Earth has been higher than it has been in hundreds of years. Around the world, people are starting to measure the effects of global warming and trying to figure out what to do about it.Scientist recently used satellites to study the temperatures of lakes around the world and they found that lakes are heating up. Between 1985 and 2009, satellites recorded the night time temperatures of the surfaces of 167 lakes. During those 24 years, the lakes got warmer by an average of about 0.045 degree Celsius per year.In some places, lakes have been warming by as much as 0.10 degree Celsius per year. At that rate, a lake may warm by a full degree Celsius in just 10 years. That difference may seem small you might not even notice it in your bath. But in a lake, slightly warmer temperatures could mean more algae (水藻) and algae can make the lake poisonous to fish.The study shows that in some regions, lakes are warming faster than the air around them. This is important because scientists often use measurements of air temperature to study how Earth is warming. By using lake temperatures as well, scientists can get a better picture of global warming. The scientists say data on lakes give scientists a new way to measure the impact of climate change around the world.That\'s going to be useful, since no matter the country is too big ortoo small can\'t ignore climate changes. Scientists aren\'t the only ones concerned. Everyone who lives on Earth is going to be affected by the rapid warming of the planet. Many world leaders believe we might be able to do something about it, especially by reducing the amount of greenhouse(温室) gases we put into the air.That\'s why the United Nations started the Framework Convention on Climate Change, orUNFCCC. Every year the convention meets, and representatives from countries around the world gather to talk about climate change and discuss global solutions to the challenges of a warming world.A slight temperature increase in a lake could be harmful forfish.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:A
答案解析:本题难度不大,答案依据比较明显,在文章第三段最后一句:But in a lake, slightly warmer temperatures could mean more algae(才(藻),and algae can make the lake poisonous to fish.谈到湖水温度上升会产生很多水藻,给湖里的鱼类带来毒害,题干和原文句意相符,答案是A。
2、A Star Is Born1 The VLT (Very Large Telescope) is the world\'s largest telescope and is taking astronomers further back to the Big Bang than they ever thought possible. Located 2,600 meters up to the Chilean Andes, it has four huge mirrors, each about the size of a London bus. The VLT is so powerful it can spot a burning match 10, 000 kilometers away. 2 This astonishing power will allow astronomers to see events in space from the birth of stars to the collision of galaxies on the edge of the cosmos. The VLT is giving astronomers their best ever view of the cosmos. The power of the VLT to see the smallest detail at the furthest distances makes its designers amazed. 3 Take the case of Eta Carinae, one of the most explosive stars in the universe. This star produces ultraviolet laser rays (紫外线) and it will destroy itself in a few million years\' time. It is five times brighter than the sun and when it explodes it is going to be a sight worth waiting for. 4 But it is at distances of millions, even billions, of light years that the VLT really shows its power. The VLT can detect light that setout on its journey before the earth even existed. This gives astronomers their first ever detailed views of events that took place in the earliest days of the cosmos. 5 In other words, the VLT is a kind of a time machine. It takes astronomers back to a time when complete galaxies crashed into each other. The effects of these past collisions can now be seen by scientists, and astronomers believe the telescope will reveal more about these exciting events in the years to come. One day, we might be able to say we have traveled back to the beginning of time, and we will have a much clearer picture of how our planet was born. The designers of the VLT are surprised at____. 【单选题】
A.its detecting power
B.millions of light years away in space
C.the location of the VLT
D.as an example
E.the birth of the earth
F.the rotation of the earth
正确答案:A
答案解析:文章第2段最后一句也概括提到了这句话的意思。
3、Houses of the FutureWhat will houses be like in thirty years\' time? No one really knows, but architects are trying to predict. What will our home be like then?Future houses will have to be flexible. In thirty years\' time even more of us will be working from home. So we will have to be able to use areas of the house forwork forpart of the day and forliving forthe rest. Families grow and change with children arriving, growing up and leaving home. The house of the future will have to grow and change with the family. Nothing will be as fixed as it is now. The house will always be changing to meet changing needs.Everyone agrees that in thirty years\' time we will be living in "intelligent" houses. We will be able to talk to our kitchen machines and discuss with them what to do. Like this, "We\'ll be having a party this weekend. What food shall we cook?" _____. We will be able to leave most of the cooking to the machines, just tasting things from time to time to check.The house of the future will be personal, each house will be different. You will be able to change the colorof the wall easily.You won\'t have to paint them-you\'ll be able to tell the wall to change the color! and if you don\'t like the colorthe next day, you will be able to have a new one. The only thing you won\'t be able to do is move the house somewhere else!【单选题】
A.You will be able to change the colorof the wall easily.
B.The only thing you won\'t be able to do is move the house somewhere else!

5、Arctic MeltEarth\'s North and South Poles are famous forbeing cold and icy. Last year, however, the amount of ice in the Arctic Ocean (北冰群) fell to a record low.Normally, ice builds in Arctic waters around the North Pole each winter and shrinks(缩小) during the summer. But formany years, the amount of ice left by the end of summer has been declining.Since 1979, each decade has seen an 11.4 percent drepin end of summer ice cover. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness, becoming 1.13 meters thinner.Last summer, Arctic sea ice reached its thinnest levels. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That\'s 38 percent less area than the average cover at that time of year. and it\'s a very large 23 percent below the previous record low, which was setjust 2 years ago. This continuing trend has made scientists concerned to.There may be several reasons forthe ice melt, says Jinlun Zhang, an oceanographer (海洋学家)at the University of Washington in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water.Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.57 Celsius warmer than the average and 1.5c warmer than the previous record.With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea, north of Alaska and western Canada, ice that measured 3.3 meters thick at the beginning of the summer was measured just 50 cm by season\'s endThe new measurements suggest that melting is far more severe than the thinking of scientists. Some scientists fear that the Arctic is stuck in a warming trend.By the end of summer 2007 the ice cover in the Arctic was ______【单选题】
A.38 million square kilometers
B.4.2 million square kilometers
C.1.13 million square kilometers
D.11.4 million square kilometers
正确答案:B
答案解析:本题难度不大,答案依据比较明显,文章第四段第二句谈到了,到2007年夏季结束时,冰层缩减至仅覆盖420万平方公里,所以答案是B。
