10．Experts from nearly 200 countries have spent the past two weeks in Warsaw，Poland．More than 9，000 representatives gathered for a United Nations conference on climate change．Organizers called the meeting to work toward a treaty（條約）to fight rising temperatures on our planet．The treaty would be signed in 2015 and take effect after 2020．
    In the United States，the Environmental Protection Agency is leading government efforts to fight climate change．The agency just ended a series of public hearings across the country．The EPA was seeking comments as it considers tightening clean air rules for coal burning power plants．
    David Doniger is a climate policy expert．He says it is the duty of the EPA to control carbon as a pollutant．He wants the agency to establish new rules that would move the United States toward a cleaner energy environment．
"No one is coming up with standards that would knock out all those power plants．We're   talking about a shift from the dirtier ones to the cleaner ones，and from all those fossil fuel-powered ones towards renewable and even nuclear sources of energy．"
    He says the government is responsible for protecting clean air，not protecting old and dirty  power stations．He says，"That's the only way that we can continue to have the way of life we want without running into the wall on climate change impacts，which in turn will destroy the quality of life we have．"

13．Several weeks ago I was at a bus station in California waiting in line to buy a ticket．As I stood there I saw a little boy （61）begging （beg） people for money so that he could buy his breakfast．Most of the travelers simply ignored the little boy or gave him a dirty look，（62）but/yet a well-dressed middle-aged man reacted differently．When（63）approached （approach） by the little boy，the gentleman looked at him and  （64）quietly （quiet） asked，"How much will you need？"I could't hear what the little boy said but watched as the gentleman pulled several notes from his wallet and calmly placed（65）them in the little boy's hands．
I don't know（66）whether the little boy actually used the money for his breakfast or for other（67）purposes （purpose）．What I do know is that I witnessed two different reactions（68）tothe same situation．I saw people who were either afraid or annoyed．And then I saw the gentleman who was not afraid and treated the homeless little boy as though he were a brother．I decided then and there that，even though we have to be（69）careful （care） in this world，I would rather I（70）behaved （behave） like the gentleman，choosing to trust what is beautiful．

1．If you think that running marathons will help you live a long and healthy life，new research may come as a shock．According to a recent scientific study，people who do a very strenuous workout are as likely to die as people who do no exercise at all．
Scientists in Denmark have been studying over 1，000joggers and non-joggers for 12years．The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die．The best speed to jog at was found to be about 5miles per hour．The research suggests that people who jog more than three times a week or at higher speeds of over 7mph die at the same rate as non-joggers．The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries（動脈）．Over time，this can cause serious injuries．
Peter Schnohr，a researcher in Copenhagen，said，"If your goal is to decrease risk of death and improve life expectancy，jogging a few times a week at a moderate pace is a good strategy．Anything more is not just unnecessary，and it may be harmful．"
The implications of this are that moderate forms of exercise such as tai chi，yoga and brisk walking may be better for us than"iron man"events，triathlons and long-distance running and cycling．According to Jacob Louis Marott，another researcher involved in the study，"You don't actually have to do that much to have a good impact on your health．And perhaps you shouldn't actually do too much"．
32．The underlined word"strenuous"in Paragraph l is closest in meaning to"A"．
A．hard    
B．regular
C．practical 
D．flexible
33．The author presents some figures in Paragraph 2toC．
A．suggest giving up jogging
B．show risks of doing sports
C．provide supportive evidence
D．introduce the research process
34．According to the scientists，why is too much exercise harmful？A
A．It may injure the heart and arteries．
B．It can make the body tired out．
C．It will bring much pressure．
D．It consumes too much energy．
35．What can be inferred from the text？D
A．No exercise at all is the best choice．
B．More exercise means a healthier life．
C．Marathons runners are least likely to die．
D．Proper exercise contributes to good health．

18．Many people say they can not start their day without first having a cup of coffee or tea．People say these drinks help them think clearly and feel more awake．This is because of  caffeine，a kind of matter found in some plants．Caffeine helps to give a jumpstart to the  nervous system．Now a new report says it may also improve long-term memory．
    Michael Yassa is a neurobiology professor at the University of California．He and other  researchers wanted to know if caffeine could improve what they called memory consolidation．They asked a group of individuals to learn something new，then the same people were given caffeine，the active component in coffee，tea and chocolate．
    He and the other researchers worked with a group of l60 people who were Caffeinefree．On the first day，all the subjects were shown pictures of everyday objects．They were asked to identify whether the pictures could be found inside the house or outdoors．Some of the subjects were then given a caffeine pill，the others were given a placebo-a pill containing an inactive thing．On the second day，all of the subjects were asked to look at more pictures．Some of the images were exactly like the ones they had seen 24 hours early．But other images were different．And a third group of pictures was similar to the first group but a little different．The participants had to decide whether the images they saw were the same or different from the ones on the first day．
    Professor Yassa says their answers help to show the effects of caffeine on memory．He  says those who took the caffeine pills had a ten to twelve percent increase in their ability to   remember the objects．The amount of caffeine the researchers used in the study was similar to  one strong cup of coffee．

5．Starting in l972，the National Park Service established a policy for forest fires calle Natural Burn．It was acknowledged that some forest fires，such as those caused by lightning were necessary for forests to maintain balanced ecosystems，so the fire should be allowed to burn．However，a big fire in Yellowstone National Park in l988 caused this policy to be abandoned since the fire was initially allowed to burn yet soon out of control．As a result，the fire of l988 destroyed much of Yellowstone，which is America's oldest and most beloved national park．Massive areas of plants were destroyed，and large empty spaces and acres of burned and blackened trees greeted visitors．The rivers and streams were choked with ash，and the ecosystem of the park was changed beyond repair．
    In addition，great numbers of animals were killed by the fires that bumed out of control．The fires were driven by high winds，moving as many as ten miles a day．Many small animals died in the flames．The fires'rapid advances gave the wildlife little chance to escape．Even today，few of these small forest animals have returned to live in the park．In the years immediately following the fires，the numbers of visitors declined rapidly．No one was interested in seeing a blackened and treeless park on vacation．Yellowstone had previously been famous for its amazing views and unique geological formations such as the geyser Old Faithful．But now its reputation as America's wonder is damaged permanently．

15．Not very long ago，the question would have seemed absurd．Now it is on the lips of respected scientists； MPs（議員） are beginning to talk of"a war on sugar"，and even England's chief medical officer has said sugar may have to be，like the old enemy tobacco，taxed in order to protect the nation's health．
There came a time in the evolution of public attitudes to smoking，when the doctors had been shouting for long enough that the public was broadly aware of the risks and the only question left，for Government was：what should we do about it？
Some believe we are now at the same point in our attitudes to sugar．Others-largely but not only representatives of the food and drink industry-say the entire debate has been skewed，（歪曲） by those who spread stories deliberately to make people nervous．
More or less everyone agrees that eating too much sugar is bad for you．There is also no doubt obesity is a growing problem which is putting a significant，avoidable burden on the NHS by increasing the rates of diabetes，heart disease and other long-term conditions．
But to what extent is sugar-rather than saturated fats，or salt，carbohydrates or proteins，or any of the other devils of modem diets-the cause of obesity and how much should we worry about it？
Yesterday，hopes of achieving anything resembling clarity（清楚） from the World Health Organization （WHO） were confused once again，which，widely expected to reduce the recommended sugar intake by a half in new draft guidance，instead said it would continue to recommend that sugar make up no more than 10per cent of the energy we consume，while adding that cutting this to five per cent would have"additional benefits"．The decision will now go out to public consultation．
Simon Capewell，professor of the University of Liverpool，said that he suspected"dirty work"on the part of food and drinks companies might lie behind the WHO's less than resounding message．
"The food industry say Government has no business interfering（介入） in families，we must protect personal choice，"Professor Capewell said．"We say there is no personal choice．At the moment，a mother can walk into a supermarket with a choice of four tomato soups-with three，or four，or five teaspoons of sugar in them．She has a choice of thousands of ready meals-with five，or six，or even nine teaspoons of sugar in．"

59．By referring to smoking the author indicates thatB．
A．sugar has just turned out to be as harmful as smoking
B．it is not easy for authorities to restrict or ban something
C．it is easy for people to see bad effects of something
D．people must see the disadvantages of sugar immediately
60．WHO has changed its idea mainly becauseC．
A．it thinks the danger of sugar to health is overemphasized
B．it finds it safe to take in as much sugar as people do now
C．it believes certain amount of intake of sugar does us good
D．it has been put under pressure by food and drinks companies
61．When reporting the argument about sugar，the author seems toB．
A．remain objective                    B．stand by those against it
C．believe it harmless                 D．hold the view of"wait-and-see"
62．Which of the following can be the proper title for the passage？A
A．Is sugar the new evil？B．How much sugar do you take daily？
C．Is sugar to be taxed？D．How much do you know about sugar？
