2．There are three separate sources of danger in supplying energy by unclear power．
First，the radioactive material must travel from its place of production to the power station．Although the power stations themselves are strongly built，the containers used for the transport of the materials are not．Normally，only two methods of transport are in use，namely road or rail．Unfortunately，both of these may have an effect on the general public，since they are sure to pass near，or even through，heavily populated areas．
Second，there is the problem of waste．All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years．It is impossible to make these wastes nonradioactive，and so they must be stored in one of the inconvenient ways that scientists have invented．For example，they may be buried under the ground，or dropped into deserted mines，or sunk in the sea．However，these methods do not solve the problem，since an earthquake could easily break the containers．
Third，there may occur the danger of a leak or an explosion at the power station．As with the other two dangers，this is not very likely，so it does not provide a serious objection to the nuclear program．However，it can happen．
Separately，these three types of dangers are not a great cause for worry．Taken together，though，the probability of disaster is extremely high．

56．The author thinks that the ways to store nuclear wastes areB．
A．easy   B．ineffective   C．reasonable   D．impossible
57．What do we learn from the last paragraph？A
A．By itself，none of the three dangers is likely to cause worry．
B．The dangers of nuclear energy can certainly be avoided．
C．The general public are strongly against the nuclear program．
D．The power station itself is a very safe place．
58．What is this passage about？C
A．Uses of nuclear power．      B．Public anger at nuclear power．
C．Dangers from nuclear power． D．Accidents caused by nuclear power．

分析 文章主要讲述了核能的危险性，包含三个方面：运输路径；浪费问题和核泄漏．

解答 56-58 BAC
56题答案是B．推理判断题．根据文章第2，3，4段since they are sure to pass near，or even though，heavily populated areas．和However，these methods do not solve the problem，since an earthquake could easily break the containers．以及so it does not provide a serious objection to the nuclear program．However，it can happen．说明这三种方法都有很多的危险性，并不是十分的有效．故选B．
57题答案是A．推理判断题．根据本段Separately，these three types of dangers are not a great cause for worry．Taken together，though，the probability of disaster is extremely high．如果把这三种危险合在一起，那么就很危险了，也就是说核材料本身就是十分危险的．故选A．
58题答案是C．主旨大意题．文章主要讲述了核能的危险性．故选C．

点评 这是一篇关于核能的危险性的阅读题．题目设计推理判断题．要在抓住关键句子的基础上合理地分析才能得出正确答案；考查文章大意的题需要对文章大意有清晰的理解才能得出正确答案，切记胡乱猜测，一定要做到有理有据．

D．People's attitudes towards Smart Grid technology
E．The supporting system of Smart Grid technology
F．The challenges Smart Grid technology meet with
76．B
There are increasing fears of global warming．Consequently，many countries are focusing on the switch to a low carbon economy．This shift will lead to major changes in the supply and use of electricity．To meet these challenges，countries are investing in Smart Grid （智能电网） technology．This system aims to provide the electricity industry with a better understanding of power generation and demand to create a more efficient power network．
77．E
Smart Grid technology basically involves the application of a computer system to the electricity network．The computer system can be used to collect information about supply and demand and improve engineer's ability to manage the system．With better information about electricity demand，the network will be able to increase the amount of electricity delivered per unit generated，leading to potential reductions in fuel needs and carbon emissions （排放）．
78．A
Smart Grid technology is profitable to consumers too．They will be able to collect real-time information on their energy use for each appliance．Varying tariffs （收费标准） throughout the day will give customers the motivation to use appliances at times when supply greatly exceeds （超过） demand，leading to great reductions in bills．
79．F
With these changes comes a range of things to be overcome．The first involves managing the supply and demand．Sources of renewable energy，such as wind，wave and solar，are unpredictable，and nuclear power，which is also set to increase as nations switch to alternative energy sources，is inflexible．A second problem is the fact that many renewable power generation sources are located in remote areas，such as windy uplands and coastal regions．
80．D
Although Smart Technology is still in its infancy，experimental plans to promote and test it are already underway．Consumers are currently testing the new smart meters which can be used in their homes to manage electricity use．Cities are investing money into smart energy，due to the high population density and high energy use．It is here where Smart Technology is likely to be promoted first，making use of a range of sustainable （可持续的） power sources，transport solutions．

7．"People should have one meat-free day a week if they want to make a personal and effective sacrifice that would help deal with climate change，"the world's leading authority on global warming has told The Observer．
Dr Rajendra Pachauri，chair of the United Nations Intergovernmental Panel on Climate Change，said that people should then go on to reduce their meat consumption even further．
Pachauri，who was re-elected the panel's chairman for a second six-year term last week，said diet change was important because of the huge greenhouse gas emissions （排放） and other environmental problems associated with raising cattle and other animals．"It was relatively easy to change eating habits compared to changing means of transport，"he said．
The UN's Food and Agriculture Organisation has estimated that meat production accounts for nearly a fifth of global greenhouse gas emissions．These are produced during the production．For example，ruminants （反刍动物），particularly cows，give off a gas called methane，which is 23times more effective as a global warming agent than CO2．
Pachauri can expect some opposite responses from the food industry to his advice，though last night he was given unexpected support by Masterchef presenter and restaurateur John Torode．"I have a little bit and enjoy it，"said Torode．"Too much for any person is bad．But there's a bigger issue here：where the meat comes from．If we all bought British and stopped buying imported food，we'd save a huge amount of carbon emissions．"
Professor Robert Watson，the chief scientific adviser for the Department for Environment Food and Rural Affairs，said government could help educate people about the benefits of eating less meat，but it should not regulate．"Eating less meat would help，there's no question about that，"Watson said．
However，Chris Lamb，head of marketing for pig industry group BPEX，said the meat industry had been unfairly targeted and was working hard to find out which activities had the biggest environmental impact and reduce them．"Some ideas were contradictory，"he said．"For example，one solution to emissions from cattle and other animals was to keep them indoors，but this would damage animal welfare．Climate change is a very young science and our view is there are a lot of simple solutions being proposed．"

14．LOS ANGELES （Reuters）---Onions make you cry，add flavor to food and are talked about a lot for their medicinal benefits．Now the vegetable has another use---powering up green energy．
A new system debuts on Friday that changes onion juice into electricity at Gills Onions，the largest fresh onion processor （加工机） in the United States．
The Oxnard，California-based company expects its new onion-fueled power to reduce its electric bill by﹩700，000 a year and cut its annual greenhouse gas releasing by up to 30，000 tons．The happy ending to this green energy tale，however，generated another question：how to get rid of onion waste．"When we peel an onion，35 to 40 percent of the onion comes off before we have a usable onion．That's the top，tail and skins around the onion before you get to the meat，"said Steven Gill，co-owner of the 25-year-old company．
They used to take the waste to the fields for composting （堆肥） but that became a problem as it cost too much．Ten years ago，Gill started looking at technology for a solution．"We ended up destroying the skins as they c ome out of the plant and extracting all the juice，which is very high in sugars，and bacteria love it，"Gill said．
In the new system，bacteria produce methane gas（沼气） from the juice．The gas then goes to two 300 kilowatt fuel cells，creating enough power for 460 homes．The company expects to get 35 to 40 percent of its electricity from this new system．
The company invested﹩9.5 million in the project and will receive﹩2.7 million from Southern California Gas Co．，a regulated subsidiary of Sempra Energy，as part of a state program to encourage self-contained generation by businesses．In addition to cutting its electric bill，the company will save﹩400，000 in costs of taking the waste to the fields and expects pay-back in six years．
The onion grower now has a new goal：to be a zero-waste facility by 2013．
"We wanted to follow it all the way through and make the full circle，"Gill said．

11．Here's a new warning from health experts：Sitting is deadly．Scientists are increasingly warning that sitting for prolonged periods-even if you also exercise regularly-could be（36）Afor your health．And it doesn't matter where the sitting takes place-at the office，at school，in the car or before a computer or TV-just the overall number of hours it（37）B
Research is preliminary，but several studies（38）Cpeople who spend most of their days sitting are more likely to be fat，have a heart attack or even die．
In an editorial（39）Dthis week in the British Journal of Sports Medicine，Elin Ekblom-Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define（40）Bactivity to highlight the dangers of sitting．
While health officials have issued guidelines（41）Cminimum amounts of physical activity，they haven't suggested people try to limit how much time they spend in a seated（42）D
"After four hours of sitting，the body starts to send（43）Asignals，"Ekblom-Bak said．She explained that genes regulating the amount of glucoseand fat in the（44）Cstart to shut down．
Even for people who（45）D，spending long stretches of time sitting at a desk is still harmful．Tim Armstrong，a physical activity expert at the World Health Organization，said people who exercise every day（46）Cstill spend a lot of time sitting-might get more benefit if that exercise were spread across the day．（47）Ain a single bout．

"I'm sure there are some detrimental（51）Aof staying still for too long，but I hope that being（52）Bwhen I can helps，"he said．"I wouldn't want to think the sitting could be（53）Ddangerous．"
Still，in a study published last year that tracked more than 17，000 Canadians for about a dozen years，researchers found people who sat（54）Chad a higher death risk，independently of whether or not they exercised．

12．Women who own cats are more likely to have mental health problems and kill themselves because they can be infected by a common parasite that can be caught from cat litter，a study has found．
Researchers found women infected with the Toxoplasma gondii （T．gondii） parasite（刚地弓形虫），which is spread through contact with cat waste or eating undercooked meat or unwashed vegetables，are at increased risk of attempting suicide．
The study involved more than 45，000women in Denmark．About a third of the world's population is infected with the parasite，which hides in cells in the brain and muscles，often without producing symptoms．
The infection，which is called toxoplasmosis（弓形虫病），has been linked to mental illness，such as schizophrenia（精神分裂症），and changes in behavior．
The study's senior author Doctor Teodor Postolache，an associate professor of psychiatry（精神病学） at the University of Maryland School of Medicine in the United States，said，"We can't say with certainty that T．gondii caused the women to try to kill themselves，but we did find a predictive association between the infection and suicide attempts later in life that deserves additional studies．"
Doctor Albert Reece，vice president of medical affairs at the University of Maryland，said，"T．gondii infection is a major public health problem around the world，and many people don't realize they're infected．
"Dr Postolache is a leading expert on suicide neuroimmunology（神经免疫学）．Suicide is a critically important mental health issue．About one million people commit suicide and another 10million attempt suicide worldwide each year．We hope that this type of research will one day help us find ways to save many lives that now end too early in suicide．"
Dr．Postolache's research team at the University of Maryland was the first to report a connection between T．gondii and suicidal behavior in 2009．He is cooperating with researchers in Denmark，Germany and Sweden to confirm and investigate the way leading to this association．
The T．gondii parasite thrives in the intestines of cats，and it is spread through their waste．All warm-blooded animals can become infected through contact with it．Humans can become infected by changing their infected cats'litter boxes，eating unwashed vegetables，drinking water from a polluted source，or by eating undercooked or raw meat．
Not washing kitchen knives after preparing raw meat before handling another food item also can lead to infection．Pregnant women can pass the parasite directly to their unborn babies and are advised not to change cat litter boxes to avoid possible infection．
Babies don't produce antibodies to T．gondii for three months after they are born，so the antibodies present in their blood represented infection in the mothers．The scientists studied Danish health patients to determine if any of these women later attempted suicide，including cases of violent suicide attempts which may have involved guns，sharp instruments and jumping from high places．
The study found that women infected with T．gondii were one and a half times more likely to attempt suicide compared to those who were not infected，and the risk seemed to rise with increasing levels of the T．gondii antibodies．
Dr Postolache noted limitations to the study，such as the inability to determine the cause of the suicidal behavior．
The findings were published online in the Archives of General Psychiatry．
50．The objects of the research are women fromA．
A．Demark B．the USA C．Germany D．Sweden
51．The common way which is more likely to be infected with the disease isB．
A．to eat unwashed vegetables or undercooked meat
B．to clean a place where a cat once lived for a time
C．to pass the infection to her unborn baby during a woman's pregnancy
D．to reuse kitchen tools which have been used to cut raw meat
52．What is the consequence if a woman is infected with the parasite in the passage？B
A．Having a high fever．
B．Doing deliberate self-harm．
C．Keeping a depressed mood．
D．Becoming bad tempered．
53．What can be inferred from the passage？C
A．Women have a higher risk to be infected by the parasite than men．
B．The result of the research may help the scientists to find ways to stop suicide in advance．
C．The scientists will continue their research into the possible connection．
D．The risk of being infected seems to rise with the decreasing levels of the antibodies．
54．Which of the following statements would probably be the best title of the passage？D
A．Why are women more likely to commit suicide？
B．Women should keep away from cats．
C．Ways found to deal with women's mental problems．
D．Are women who own cats at a suicide risk？
