2．Doctor are known to be terrible pilots．They don't listen because they already know it all．I was lucky：became a pilot in 1970，almost ten years before I graduated from medical school．I didn't realize then，but becoming a pilot makes me a better surgeon．I loved flying．As I flew bigger，faster planes，and in worse weather．I learned about crew resource management （機組資源管理），or CRM，a new idea to make flying safer．It means that crew members should listen and speak up for a good result，regardless of positions．
I first read about CRM in 1980．Not long after that，an attending doctor and I were flying in bad weather．The controller had us turn too late to get our landing ready．The attending doctor was flying； I was safety pilot He was so busy because of the bad turn，he had forgotten to put the landing gear （起落架） down．He was a better pilot-and my boss-so it felt unusual to speak up．But I had to：Our lives were in danger．I put aside my uneasiness and said，"We need to put the landing gear down now!"That was my first real lesson in the power of CRM，and I've used it in the operating room ever since．
CRM requires that the pilot/surgeon encourage others to speak up．It further requires that when opinions are from the opposite，the doctor doesn't overreact，which might prevent fellow doctors from voicing opinions again．So when I'm in the operating room，I ask for ideas and help from others．Sometimes they're not willing to speak up．But I hope that if I continue to encourage them，someday someone will keep me from"landing gear up"．

56．What does the author say about doctors in general？B．
A．They like flying by themselves．B．They are unwilling to take advice．
C．They pretend to be good pilots．D．They are quick learners of CRM．
57．The author deepened his understanding of the power of CRM whenA．
A．he saved the plane by speaking upB．he was in charge of a flying task
C．his boss landed the plane too lateD．his boss operated on a patient
58．In the last paragraph"landing gear up"probably meansD．
A．following flying requirements．B．overreacting to different opinions．
C．listening to what fellow doctors sayD．making a mistake that may cost lives
59．Which of the following can be the best title for the text？B．
A．CRM：A New Way to Make Flying SafeB．Flying Makes Me a Better Doctor
C．The Making of a Good PilotD．A Pilot-Turned Doctor．

3．In the United States alone，over 100million cell-phones are thrown away each year．Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants．The electronic waste stream is increasing three times faster than traditional garbage as a whole．
Electronic devices contain valuable metals such as gold and silver．A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste，the concentration （含量） of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals．
Electronic wastes also contain many poisonous metals．Even when the machines are recycled and the harmful metals removed，the recycling process often is carried out in poor countries，in practically uncontrolled ways which allow many poisonous substances to escape into the environment．
Creating products out of raw materials creates much more waste material，up to 100times more，than the material contained in the finished products．Consider again the cell-phone，and imagine the mines that produced those metals，the factories needed to make the box and packaging（包裝） it came in．Many wastes produced in the producing process are harmful as well．
The U．S．Environmental Protection Agency notes that most waste is dangerous in that"the production，distribution，and use of products-as well as management of the resulting waste-all result in greenhouse gas release．"Individuals can reduce their contribution by creating less waste at the start-for instance，buying reusable products and recycling．
In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive （動機） for reducing waste．If producers are required to take back packaging they use to sell their products，would they reduce the packaging in the first place？
Governments'incentive to require producers to take responsibility for the packaging they produce is usually based on money．Why，they ask，should cities or towns be responsible for paying to deal with the bubble wrap （氣泡墊） that encased your television？
From the governments'point of view，a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers．

58．By mentioning the Swiss study，the author intends to tell us thatB．
A．the weight of e-goods is rather small
B．E-waste deserves to be made good use of
C．natural minerals contain more precious metals
D．the percentage of precious metals is heavy in e-waste
59．The responsibility of e-waste treatment should be extendedB．
A．from producers to governments
B．from governments to producers
C．from individuals to distributors
D．from distributors to governments
60．What does the passage mainly talk about？D
A．The increase in e-waste．
B．The creation of e-waste．
C．The seriousness of e-waste．
D．The management of e-waste．

3．We've reached a strange-some would say unusual-point．While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization （WHO），more people now die from being overweight，or say，from being extremely fat，than from being underweight．It's the good life that's more likely to kill us these days．
　　Worse，nearly l8 million children under the age of five around the world are estimated to be overweight．What's going on？
　　We really don't have many excuses for our weight problems．The dangers of the problem have been drilled into us by public-health campaigns since 2001 and the message is getting through-up to a point．
　　In the 1970s，Finland，for example，had the highest rate of heart disease in the world and being overweight was its main cause．Not any more．A public-health campaign has greatly reduced the number of heart disease deaths by 80 per cent over the past three decades．
　　Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005，and doctors even offer surgery of removing fat inside and change the shape of the body．That has become a sort of fashion．No wonder it ranks as the world's most body-conscious country．
　　We know what we should be doing to lose weight-but actually doing it is another matter．By far the most popular excuse is not taking enough exercise．More than half of us admit we lack willpower．
　　Others blame good food．They say：it's just too inviting and it makes them overeat．Still others lay the blame on the Americans，complaining that pounds have piled on thanks to eating too much American-style fast food．
　　Some also blame their parents-their genes．But unfortunately，the parents are wronged because they're normal in shape，or rather slim．
　　It's a similar story around the world，although people are relatively unlikely to have tried to lose weight．Parents are eager to see their kids shape up．Do as I say-not as I do．

59．What is the"strange"point mentioned in the first sentence？A
A．The good life is a greater risk than the bad life．
B．Starvation is taking more people's lives in the world．
C．WHO report shows people's unawareness of food safety．
D．Overweight issue remains unresolved despite WHO's efforts．
60．Why does the author think that people have no excuse for being overweight？
C
A．A lot of effective diet pills are available．
B．Body image has nothing to do with good food．
C．They have been made fully aware of its dangers．
D．There are too many overweight people in the world．
61．The example of Finland is used to illustrateC
A．the cause of heart disease                       　　
B．the fashion of body shaping
C．the effectiveness of a campaign               　　
D．the history of a body-conscious country
62．Which would be the best title for the passage？A
A．Actions or Excuses？
B．Overweight or Underweight？
C．WHO in a Dilemma                              　　
D．No Longer Dying of Hunger．
