2014高考英语抓分训练：时闻型阅读理解(限时：25分钟)amit researchers and their colleagues are working to find out whether energy from trees can power a network of sensors (传感器) to prevent spreading forest fires. what they learn could also raise the possibility of using trees as silent guards along the nations borders to discover potential threats such as smuggled (走私的) radioactive materials. the us forest service currently predicts and tracks fires with a variety of tools, including remote automated weather stations. but these stations are expensive and sparsely (稀疏地) distributed. additional sensors could save trees by providing better local climate data to be used in fire prediction models and earlier warnings. however, recharging or replacing batteries by hand at very hardtoreach locations makes it impractical and costly. the new sensor system seeks to avoid this problem by developing trees into a selfsustaining power supply. each sensor is equipped with a battery that can be slowly recharged using electricity produced by the tree. “a single tree doesnt generate a lot of power, but over time the trickle (细流) charge adds up, just like _”， said shuguang zhang, one of the researchers on the project and the associate director of the mits centre for biomedical engineering (cbe)the system produces enough electricity to allow the temperature and humidity sensors to wirelessly send out signals four times a day, or immediately if theres a fire. each signal spreads from one sensor to another, until it reaches an existing weather station that sends the data by satellite to a forestry command centre in boise, idaho. scientists have long known that trees can produce extremely small amounts of electricity. but no one knew exactly how the energy was produced or how to take advantage of the power.1what are the disadvantages of the remote automated weather stations?athey cost too much.bthey are of poor quality.cthey are not enough.dthey cant reach remote places.aa, b bb, d ca, c db, c2which of the following is the best sentence to fill in the blank?afar water does not put out near fire.ball rivers run into the sea.cmany a little makes a mickle.dit never rains but it pours. 3what shuguang zhang said in paragraph 4 means that _aa single tree is enough to generate much power bthe power from the tree cant be storedctrees can generate enough power for our lifeda tree can produce the electricity to meet the needs of a sensor4what would the author talk about after the last paragraph of the passage?athe amount of electricity trees produce.bhow trees produce electricity.ctrees contribution to society.dthe research process of tree power.5what would be the best title for the passage?apreventing forest fires with tree powerbtrees can produce electricityctree power in daily lifeddeveloping new energyb(new york) a french tourist highly praised for rescuing a twoyearold girl in manhattan said he didnt think twice before diving into the freezing east river.tuesdays daily news said 29yearold julien duret from france was the man who left the spot quickly after the rescue last saturday.he lifted the little girl out of the water after she fell off the bank at the south street seaport museum. he handed the girl to her father, david anderson, who had dived in after him.“i didnt think at all，” duret told the daily news. “it happened very fast. i reacted very fast.”duret, an engineer on vacation, was walking with his girlfriend along the pier(码头) when he saw something falling into the water. he thought it was a doll, but realized it was a child when he approached the river. immediately, he took off his coat and jumped into the water.when he reached the girl, she appeared lifeless, he said. fortunately, when she was out of the water, she opened her eyes.anderson said his daughter slipped off the bank when he was adjusting his camera. an ambulance came later for her, said duret, who was handed dry clothes from onlookers. duret caught a taxi with his girlfriend shortly after.the rescue happened on the day before he left for france. duret said he didnt realize his story of heroism had greatly moved new york until he was leaving the city the next morning.“i dont really think im a hero，” said duret. “anyone would do the same thing.”1why was duret in new york?

aa careless fatherba poor girl cwarmhearted onlookersdbrave frenchman foundcscientists have not found any signs of life on mars yet, but they say a robotic vehicle called “curiosity” is helping them learn a lot about the planets history and climate.curiosity landed on mars in august 2012 after travelling through space for more than eight months. it was sent to mars by scientists from nasa in the united states.curiosity is about the size of a car and has six wheels. it also has a robotic arm, cameras, and instruments that allow it to examine things it finds on the surface. then it sends the information back to the earth.curiositys main task is to find out if anything could live on mars, either now or in the past. on nov. 2, nasa scientists held a press conference (新闻发布会) to discuss what curiosity had found in its first two months on mars.curiosity has found soil that is similar to the sand formed by volcanoes (火山) on the earth. scientists say that studying the minerals in martian soil will help them understand what conditions were like on the planet in the past. curiosity also found smooth stones like the ones found on river beds and seashores on the earth, where their rough edges have been worn down by water. mars is very cold and dry now, but scientists say the smooth stones tell them that a river used to run through the place where they were found.curiosity has been testing the atmosphere around mars for a type of gas called methane (甲烷), but so far it has not found any. on the earth, most methane is produced by plants or animals. methane on mars might indicate that some type of tiny plants or animals lived there.curiosity is the fourth robotic vehicle to be sent to mars. it will continue to explore the planet for about two years.1. which of the following descriptions about curiosity is true?ait landed on mars in january 2012.bit is small in size and has four arms.cit took over eight months to arrive in mars.dit was sent to mars by scientists from russia.2. according to the information sent back by curiosity, scientists believe that_atheres no air on marsbmars is warm and wet nowcthe soil on mars is richdthere used to be water on mars3. the underlined word “they” in paragraph 5 refers to“_”asmooth stonesbriverscrobotic vehiclesdvolcanoes4. we know from the sixth paragraph that_asome tiny animals once lived on marsbthere are no plants or animals on mars nowcthe atmosphere around mars is full of methanedcuriosity is designed to test the atmosphere around the earth5. what is the main idea of the passage?ahumans benefit a lot by going to mars.bscientists will stop the research on mars soon.cit is possible to build an earthlike environment on mars.da robotic vehicle helps scientists get
