spreading forest fires What they learn could also raise the possibility of using trees as silent guards along the nation s borders to discover potential threats such as smuggled 走私的 radioactive materials The U S Forest Service currently predicts and tracks fires with a variety of tools including remote automatic 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 hard to reach locations makes it impractical and costly The new sensor system seeks to avoid this problem by developing trees into a self sustaining power supply Each sensor is equipped with a battery that can be slowly recharged using electricity produced by the tree A single tree doesn t 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 MIT s Center 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 there s 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 center 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 1 What are the disadvantages of the remote automatic weather stations a They cost too much 用心 爱心 专心2 b They are of poor quality c They are not enough d They can t reach remote places A a b B b d C a c D b c 2 Which of the following is the best sentence to fill in the blank A Far water does not put out near fire B All rivers run into sea C Many a little makes a mickle D It never rains but it pours C Tree power in daily life D Developing new energy 二 The crisis at Japan s Fukushima Dai Ichi nuclear energy center has raised questions about the future of the nuclear energy industry Arjun Makhijani is president of the Institute for Energy and Environmental Research in the United States He says the disaster in Japan is historic This week the chairman of America s nuclear agency said there is little chance that harmful radiation from Japan could reach the United States Nuclear Regulatory Commission Chairman Gregory Jaczko also said America has a strong program in place to deal with earthquake threats No new nuclear power centers have been built in the United States since 1979 That was when America s worst nuclear accident happened at the Three Mile Island center in Pennsylvania The accident began to turn public opinion against nuclear energy To support more clean energy production the Obama government has been 用心 爱心 专心3 seeking billions of dollars in government loan guarantees to build new centers Presently about twenty percent of electricity in the United States comes from nuclear energy But critics say nuclear power is too costly and dangerous to be worth further expansion German prime minister Angela Merkel said Germany would close all seven nuclear power centers for a moment while energy policy is reconsidered The European Union is planning to test all centers in its twenty seven member nations Developing nations are less willing to slow nuclear expansion China said it would continue with plans to build about twenty five new nuclear plants And India under a cooperation agreement with the United States plans to spend billions on new centers in the coming years Japan has made nuclear energy a national priority since the 1970s Unlike many major economies Japan imports eighty percent of its energy The Nuclear Energy Institute said twenty nine percent of Japan s electricity came from nuclear sources in 2011 The government planned to increase that to forty percent by 2017 Nuclear plants supply fourteen percent of global electricity Nuclear energy is a clean resource producing no carbon gases But radioactive waste is a serious unresolved 未解决的 issue So is the presence of nuclear power centers in earthquake areas like the one ne ar Bushehr Iran 6 Which of the following countries is the least likely to expand its use of nuclear energy A China B India C Iran D Germany 7 The government of Japan intended to increase its nuclear energy in 2017 by compared with 2011 A 29 B 40 C 69 D 11 8 Which of the following statements about the use of nuclear power in the U S is TRUE A Most of the electricity comes from nuclear energy in the U S B The Obama government is against building nuclear power plants 用心 爱心 专心4 C A small number of nuclear power plants have been built since 1979 D A serious nuclear accident happened in America at the end of the 1970s 9 What s the main idea of this passage A The nuclear crisis in Japan has spread to other parts of the world B The situation of the world s nuclear power development after the crisis in Japan C Japan s nuclear disaster will slow the expansion of nuclear plants all over the world D Japan s nuclear disaster won t affect the nuclear energy production in other countries 10 From the last sentence of the passage we can see the writer s attitude towards building a nuclear power plant near Bushehr Iran is A supportive B optimistic C negative D uncertain 三 Four out of ten women who diet end up heavier than when they started watching their waistline 腰围 a study revealed today The research also showed that a large percentage of women started noticing the pounds creeping back on just 21 days after reaching their ideal weight Yesterday Dr

Six in ten said they were on a diet then and one in five women said they were on a continuous diet It found the most common triggers to start dieting was seeing their reflection in the mirror
