But, rising sea levels caused by it have resulted in the first evacuation (撤离) of an island nation the citizens of Tuvalu will have to leave their homeland. During the 20th century, sea level rose 8 12 inches. As a result, Tuvalu has experienced lowland flooding of salt water which has polluted the countrys drinking water. Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms. Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocal, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions (导致温室效应的气体排放), which are a main cause of global warming. “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years，” Laupepa told the BBC. Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries. Tuvalu is not the only country that is vulnerable (易受影响的) to rising sea levels. Maumoon Gayoon, president of the Maldives，told the United Nations that global warming has made his country of 311,000 an “endangered nation”1The text is mainly about_.Arapid changes in earths temperatureBbad effects of global warmingCmoving from a country to a new placeDreasons for lowland flooding解析：选B。主旨大意题。这篇短文主要讲述了全球变暖造成的恶劣影响。 2.According to scientists, the DIRECT cause of more and fiercer storms is_. Agreenhouse gas emissions in industrialized nations Bhigher surface water temperatures of the sea Ccontinuous global warming Drising sea levels解析：选B。细节推断题。根据第三段“Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.”可判断，造成严重的暴风雨的直接原因是海洋表层水的气温升高。3Laupepa was not satisfied with the United States because it did not_. Aagree to reduce its greenhouse gas emissions Bsign an agreement with Tuvalu Callow Tuvaluans to move to the US Dbelieve the problems facing Tuvalu were real解析：选A。细节理解题。第四段第一句话表示Laupepa对美国不满意的原因是美国拒绝签署减少温室效应气体排放的公约。4. The country whose situation is similar to that of Tuvalu is_. AAustralia BNew Zealand CThe Maldives Dthe United States解析：选C。细节推断题。根据最后一段可判断出the Maldives 与Tuvalu的情况相似。BWe produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans，killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.The 16yearold Canadian high school student，Daniel Burd, from Waterloo Collegiate Institute, has discovered a way to make plastic bags degrade (分解) in as few as 3 months，a finding that won him first prize at the Canada Wide Science Fair，a $10 000 prize，a $20 000 scholarship, and a chance to revolutionize a major environmental issue.Burds strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.With this goal in mind, he ground plastic bags into a powder and concocted (调制) a solution of household chemicals, yeast (酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally，he tested the resulting bacterial culture on plastic bags，exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed (暴露) to the live bacteria was 17% lighter than the control after six weeks.The inputs are cheap：maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide. “Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer：not much. So I decided to do something myself.”said Daniel Burd.5Daniel Burd won first prize at the Canada Wide Science Fair because _. Ahe found a new kind of microorganism Bhe contributed much to environmental protection Che found a way to degrade plastics in shorter time Dhe could encourage microbes growth in an easier way解析：选C。细节理解题。从文章第二段可知，他因发现短时间降解塑料袋的方法而获奖，故答案选C项。6Daniel Burd exposed one plastic sample to dead bacteria to _. Amake the live bacteria work better Btest how effective his method was Cknow which bacteria worked faster Dcontrol the temperature in the process解析：选B。推理判断题。从文章第四段中的“.exposing one plastic sample to dead bacteria as a control”可推断，他这样做的目的在于测试他的方法是否有效，所以答案为B项。7Maintaining the required temperature takes little energy because _. Aplastics can get hot easily Bmicrobes can produce heat themselves Cmuch carbon dioxide is produced Dthe temperature can be controlled解析：选B。细节理解题。从文章倒数第二段中的“maintaining the required temperature takes little energy because microbes produce heat as they work” 可知答案选B项。8Daniel Burd got his idea from _. Ahis school textbook Bthe failure of researchers Chis everyday work Dthe practice of other people解析：选C。推理判断题。从文章最后一段丹尼尔伯德说的话可推知，他是从每天的工作中得到启发的，故答案选C项。111
