You should write at least 150 words following the outline given below： 1现在很多人热衷于各种相亲活动 2引起此现象的原因 3我的看法 Craze for Match-making 二、 Part II Reading Com

2、prehension (Skimming and Scanning) (15 minutes) Directions: In this part, you will have 15 minutes to go over the passage quickly and answer the questions attached to the passage.

3、e statement contradicts the information given in the passage; NG (for NOT GIVEN) if the information is not given in the passage. 1 Are You Ready for More? In a world of climate change, abnormal storms are the new normal. Why were unprepared for the distressing future. Joplin. Mo. , was prepared. The

4、 tornado(龙卷风 )warning system gave residents 24 minutes notice that a twister was moving quickly towards them. Doctors and nurses at St. Johns Regional Medical Center, who had practiced tornado drills for years, moved fast. And yet more than 130 people died in Joplin, including four people at St. Joh

5、ns, where the tornado sucked up the roof and left the building in ruins, like much of the shattered city. Even those who deny the existence of global climate change are having trouble dismissing the evidence of the last year. In the U. S. alone, nearly 1, 000 tornadoes have ripped across the heartla

6、nd, killing more than 500 people and causing $ 9 billion in damage. Worldwide, the 2010 heat wave in Russia killed an estimated 15, 000 people. Floods in Australia and Pakistan killed 2, 000 and left large areas of each country under water. And the temperature keeps rising: 2010 was the hottest year

7、 on earth since weather records began. From these and other extreme-weather events, one lesson is sinking in with terrifying certainty. The stable climate of the last 12, 000 years is gone. And we are not prepared. Picture California a few decades from now, a place so hot and dry the states trademar

8、k orange and lemon trees have been replaced with olive trees that can handle the new climate. Alternating floods and droughts have made it impossible for the reservoirs to capture enough drinking water. Theyre all changes that California officials believe they need to prepare for within the next dec

9、ade or two. And they arent alone. Across the U. S. , its just beginning to dawn on civic leaders that theyll need to help their communities brave coming dangers brought by climate change. Yet only 14 states are even planning, let alone implementing, climate-change adaptation plans, says Terri Cruce.

10、 a climate consultant in California. The other 36 apparently are hoping for a miracle. The game of catch-up will have to happen quickly because so much time was lost to inaction. The burning of fossil fuels has raised atmospheric levels of heat-trapping CO2 by 40% above what they were before the Ind

11、ustrial Revolution. The added heat in the atmosphere retains more moisture, builds up the energy in the system, and results in more violent and extreme weather. There is wide consensus that the 2 degrees Fahrenheit(华氏温度 )of global warming of the last century is behind the rise in sea levels, more in

12、tense hurricanes, more heat waves, and more droughts and floods. Even if the world went carbon-neutral tomorrow, wed be in for more; because of the CO2 that has already been emitted, were on track for another 5 degrees of warming. Changing temperatures will have a profound effect on the plants and a

13、nimals among us. Crops that flourished in the old climate regime will have to adapt to the new one, as some pests are already doing. Tropical diseases are reaching temperate regions. Yet most of us are naive about what climate-change adaptation will involve. At the positive extreme, “adapting“ sound

14、s as pleasant as cities planting more trees, as Chicago, New York, Boston, and scores of others are doing. And it sounds as architecturally interesting as changing roofs: New York, which is looking at an average temperature increase of up to 3 degrees Fahrenheit by 2020, is planning to paint 3 milli

15、on square feet of roofs white, to reflect sunlight and thus reduce urban heat-island effects. But those steps dont even hint at how disruptive and expensive climate-change adaptation will be. “Ten years ago. when we thought climate change would be slow and linear, you could get away with thinking th

16、at adaptation meant putting in permeable(渗水的 )pavement, so that storm water would be absorbed rather than cause floods, “says Bill McKibben, author of the 2010 book Earth. “Now its clear thats not going to be at all sufficient. Adaptation is going to have to be a lot more than changing which trees c

17、ities plant. “ States and cities will have to make huge investments in infrastructure to handle the rising sea and raging rivers. Keene. N. H. recently enlarged pipes along its highways so storm runoff would be less likely to wash out roads. In the San Francisco Bay area, planners are considering in

18、creasing the height of the seawall on the citys waterfront at the San Francisco and Oakland airports. Because warmer air provides less lift, airport runways the world over will have to be lengthened in order for planes to take off. In Norfolk, Va. , where the combination of global sea-level rising a

19、nd local-land sinking has brought water levels 13. 5 inches higher since 1930, the city has fought a battle to stay ahead of the tide by elevating one often-flooded roadway by 18 inches. An expected sea-level rise there of twice the global average means that 371 miles of highway are at risk of looki

20、ng more like canals, while 2, 500 historic and archeological sites could become real-life versions of Atlantis. In Alaska, six native villages on the coast, including Newtok and Shishmaref, are likely to get swamped as seas rise and storm surges intensify. They also sit on permafrost(永冻层 ). which is

21、nt “perma“ anymore. As the ground melts beneath the villages, the state is figuring out how and where to relocate them. The U. S. could take some advice from other countries like the Netherlands, which has more than a little experience keeping the ocean at bay. As part of a 200-year plan, the countr

22、y has launched a 1. 5 billion project to broaden river channels so they arent overwhelmed as a result of the higher flows. Rotterdam raised by two feet a storm gate at the port that holds back the(rising)North Sea, and elevated the ground the new 1. 700-acre port sits on by a foot and a half to keep

23、 it from being submerged. all at a cost of some 50 million. All told. it will soon be spending some 4 billion a year to cope with what will happen. Britain, too, is taking adaptation seriously, planning to raise the height of the floodgates protecting central London from the Thames by 12 inches. So

24、what lies behind Americas resistance to action? Economist Sachs points to the lobbying power of industries that resist acknowledgment of climate changes impact. “The country is two decades behind in taking action because both parties are controlled by Big Oil and Big Coal, “ says Sachs. But the pion

25、eers of action isnt waiting any longer. This week, representatives from an estimated 100 cities are meeting in Bonn, Germany, for the 2nd World Congress on Cities and Adaptation to Climate Change. As Joplin, Mo. . learned in the most tragic way possible, against some impacts of climate change, mans

26、minor efforts are useless. But time is getting short, and the stakes are high. Says Daniel Sarewitz. a professor of science and society at Arizona State University: “Not to adapt is to put millions of people to death and breakdown. “ 2 Since human beings had weather records, the temperature in 2010
