17．If you know the following fact，you'll understand why many people suffer from foot problems．The average person walks the equivalent of three times around the Earth in a lifetime．That is enormous wear and tear on the 26 bones，33 joints and more than 100 muscles that make up the foot．
In a recent survey for the American Podiatric Medical Association，53 percent of respondents reported foot pain so severe that it affected their daily function．On average，people develop pain in their 60s，but it can start as early as the 20s and 30s．And usually women give care to their feet while men don't．"A lot of people think foot pain is part of the aging process and accept it，and  walk with pain，"said Dr Andrew Shapiro．Though some foot problems are inevitable，their progress can be slowed．The following questions will help you assess whether you should take more preventive action as you age．Do you have flat feet or hig harches（足弓）？Either puts feet a trisk．Shoes that support the arch and heel can help flat feet．People with high arches should look for roomy shoes and soft erpadding（襯墊）to absorb the shock．Proper exercises also strengthen muscles，supporting the foot．
Do your shoes fit？In the survey，more than 34 percent of men said they could not remember the last time their feet were measured.20 percent of women said that once a week they wore shoes that hurt，and 8 percent wore painful shoes daily．Feet flatten and lengthen with age，so if you still stick to the shoe size you wore at the age of 21，get your feet measured．Do you walk？Putting more mileage（里程）on your feet is the best way to exercise the muscles and keep them healthy．

43．The underlined phrase"wear and tear"in Paragraph 1 probably meansC．
A．a(chǎn)  surprising experience    
B．a(chǎn)n unimaginable distance   
C．damage due to continuous use
D．a(chǎn) contribution to the feet
44．What do we know from the passageC？
A．The number of men and women who have foot problems is similar．  
B．Walking as little as possible can protect your feet from pain．    
C．More than half of there spondent shave serious foot problems．   
D.53% of people develop foot pain in their 60s．
45．Which of the following statements best explains foot painA？
A．Not all of it can be avoided．  
B．People can't slow its process．   
C．Walking more will stop foot pain．  
D．Preventive actions can't work well．
46．If your feet are 26cm long at 23，what is the probable length of your feet when you are 43？A
A.26.2cm   
B.25.2cm   
C.26cm   
D.25cm．

5．Researchers may have discovered a perfect material of dieting----low fat cake and cheese．
British researchers say they have created a protein （蛋白質(zhì)） that fat perfectly．
The proteins will enable food producers to remove much of the fat used in their products but without reducing product quality．
Funded by team from University of Edinburgh，the researchers have produced the modified （調(diào)整了的） proteins that easily break down and therefore work nearly the same as the fats do during food production．
"We've paved the way for the development of modified proteins that can be used to produce a wider ranger of appealing low-fat foods，"said Dr．Steve Euston，who led the research．
"The result could be important for health benefits，as well as a reduction in the burden on the National Health Service （NHS） caused by many weight-related health problems．"
Protein-for-fat substitution （替代品） is not a completely new idea，but to date it has been limited to products such as yogurts．
In cheeses and cakes it has proved less successful in ensuring the original taste and texture fundamental to consumer satisfaction，mainly because proteins could not mimic the behavior of fats closely enough．
By studying the proteins'chemical structure，the team has developed a detailed understanding of how proteins behave when they are heated or go through other food producing processes．
The proteins could encourage development of a wider choice of low-fat foods，helping consumers to eat more healthily and reducing weight-related health problems．
The team has achieved particularly promising results in using proteins to replace eggs，which is commonly used in bakery items．
Such substitution not only cuts fat content； because eggs can be subject to sharp changes in price，it could also cut the cost products and so encourage consumers to eat more healthily．

47．What can we learn from the passage？A
A．The NHS will benefit from this new finding．
B．the research team is funded by food producers．
C．Protein for fat substitution is a completely new idea．
D．Products of modified proteins have been put on sale．
48．The underlined word"mimic"meansD
A．reduces 
B．makes 
C．removes 
D．imitates
49．These new proteins work nearly the same as the fats do becauseB．
A．they will cut fat content easily 
B．they will break down easily
C．their products are cheaper and healthier 
D．they ensure the original taste and texture．
50．Which of the following is best title？A
A．A Special Protein 
B．How Proteins Work
C．Cut down the Food Cost 
D．A special Research Team．

12．For years，there has been a bias （偏見(jiàn)） against science among clinical psychologists （臨床心理學(xué)家）．In a two-year analysis to be published in November in Perspectives on Psychological Science，psychologists led by Timothy B．Baker of the University of Wisconsin charge that many clinical psychologists fail to"provide the treatments for which there is the strongest evidence of effectiveness"and"give more weight to their personal experiences than to science．"As a result，patients have no guarantee that their"treatment will be informed by …science．"Walter Mischel of Columbia University is even crueler in his judgment．"The disconnect between what clinical psychologists do and what science has discovered is an extreme embarrassment，"he told me，and"there is a widening gap between clinical practice and science．"
The"widening"reflects the great progress that psychological research has made in identifying （確認(rèn)） the most effective treatments．Thanks to strict clinical trials，we now know that teaching patients to think about their thoughts in new，healthier ways and to act on those new ways of thinking are effective against depression，panic disorder and other problems，with multiple trials showing that these treatments-the tools of psychology-bring more lasting benefits than drugs．
You wouldn't know this if you sought help from a typical clinical psychologist．Although many treatments are effective，relatively few psychologists learn or practice them．
Why in the world not？For one thing，says Baker，clinical psychologists are"very doubtful about the role of science"and"lack solid science training"．Also，one third of patients get better no matter what treatment （if any） they have，"and psychologists remember these successes，believing，wrongly，that they are the result of the treatment．"
When faced with evidence that treatments they offer are not supported by science，clinical psychologists argue that they know better than some study what works．A 2008study of 591psychologists in private practice found that they rely more on their own and colleagues'experience than on science when deciding how to treat a patient．If they keep on this path as insurance companies demand evidence-based medicine，warns Mischel，psychology will"discredit （損傷名譽(yù)）itself．"
（Note：Answer the questions or complete the statements in NO　MORE THAN 12WORDS）

78．Clinical psychologists can't explain the effectiveness of their treatment mainly because they rely ontheir personal experience．
79．What has widened the gap between clinical practice and science？The great progress in psychological research
80．According to Baker，what are the reasons that prevent clinical psychologists from learning or practicing effective treatment？Their doubt about the role of science and inadequate science training
81．To avoid discrediting psychology，clinical psychologists need tosupport their treatment with science．

2．Scientists investigated why Ebola virus is so deadly when it spreads from animals to humans and then from human-to-human contact．The research team looked at the Zaire Ebola virus in an animal system to understand how it gains strength．This virus is responsible for the current outbreak in West Africa．They found that initially the animal systems were not affected by the virus，but succeeding transmission（傳送） into other animals caused the virus to"hot up"and become more severe．
The team analyzed the viruses at different stages and were able to identify several changes in its genetic material that were associated with increased disease．
Professor Julian Hiscox，who led the study from the University's Institute of Infection and Global Health，explains："The work tells us that the evolutionary goal of Ebola virus is to become more fatal．"
"We were able to show through genetic analysis which parts of the virus are involved in this process．The information we have gathered will now allow us to monitor for such changes in an outbreak as well as develop future treatment strategies．"
Professor Roger Hewson，leading the study from Public Health England，Porton Down，said："Ebola virus is such a destructive infection to the people affected by the disease and the economy of West Africa．"
"Our understanding of Ebola virus biology is way behind that of other viruses and our cooperation shows how we can bring together our specialists'skills to close this knowledge gap．"
Professor Miles Carroll，a co-author of the work，said："This study has allowed the team to be at the forefront of developing methodologies to analyze patient samples recently taken by the European Mobile Laboratory from West Africa to understand disease evolution during the current outbreak．"
29．What does the first paragraph mainly tell us？C
A．How severe Ebola virus is．
B．How Ebola virus spreads．
C．How Ebola virus gradually becomes deadly．
D．What contributions scientists have made on Ebola virus．
30．Which of the following statements is mentioned in the passage？B
A．In the first stage，the virus hurts its victims much．
B．As the virus spreads，it'll change and become more and more deadly．
C．The research in Ebola virus is more advanced than that in other viruses．
D．The scientists have a negative attitude to the research in Ebola virus．

9．As the pace of life continues to increase，we are fast losing the art of relaxation．Once you are in the habit of rushing through life，being on the go from morning till night，it is hard to slow down．But relaxation is essential for a healthy mind and body．
Stress is a natural part of everyday life and there is no way to avoid it．In fact，it is not the bad thing it is often supposed to be．A certain amount of stress is vital to provide motivation and give purpose to life．It is only when the stress gets out of control that it can lead to poor performance and ill health．
The amount of stress a person can withstand （經(jīng)得起） depends very much on the individual．Some people are not afraid of stress，and such characters are obviously prime material for managerial responsibilities．Others lose heart at the first sight of unusual difficulties．When exposed to stress，in whatever form，we react both chemically and physically．In fact we make a choice between"fight"or"flight"and in more primitive days the choice made the difference between life or death．The crises we meet today are unlikely to be so extreme，but however little the stress，it involves the same response．It is when such a reaction lasts long，through continued exposure to stress，that health becomes endangered．Such serious conditions as high blood pressure and heart disease have established links with stress．Since we cannot remove stress from our lives （it would be unwise to do so even if we could），we need to find ways to deal with it．

31．People are finding less and less time for relaxing themselves becauseA．
A．they are becoming busier with their work
B．they do not believe that relaxation is important for health
C．they are traveling fast all the time
D．they do not know how to enjoy themselves
32．According to the writer，the most important character for a good manager is hisD．
A．having control over performance      
B．knowing the art of relaxation
C．high sense of responsibility          
D．not fearing stress
33．Which of the following statements is true？B
A．We can find some ways to avoid stress．
B．Different people can withstand different amounts of stress．
C．It is easy to change the habit of keeping oneself busy with work．
D．Stress is always harmful to people．
34．In Paragraph 3，"such a reaction"refers back toC．
A．making a choice between‘flight'or‘fight'
B．responding to crises quickly
C．reaction to stress both chemically and physically
D．losing heart at the sight of difficulties
35．In the last sentence of the passage，"do so"refers toD．
A．expose ourselves to stress
B．find ways to deal with stress
C．established links between diseases and stress
D．remove stress from our lives．

    Builders of Dockside Green have the environment in mind with every choice they make．They ensure proper ventilation，and guarantee residents 100% fresh indoor air．Building materials，such as paints and wood，are natural and non-toxic．Eco-conscious builders use bamboo wherever possible because it can last for a long time without breaking and does not require pesticides to grow．
    Energy efficiency is one of the top priorities in Dockside Green．Not only do energy efficient appliances and light fixtures reduce the environmental impact of heating and hot water，they also save residents and business owners money．Dockside Green claims that home owners will use 55% less energy than average residents in Canada．Though they are sharing space in the apartment building，residents will have individual utility meters（公用事業(yè)電表）．Studies show that people use approximately one fifth less energy when they are billed for exactly what they use．In addition，water is treated at Dockside Green and reused for flushing toilets．
Planners of eco-communities such as Dockside Green must take the future into account．Dockside Green plans on reusing 90% of its construction waste．They also plan to continue using local suppliers for all of their transport and maintenance needs．This is a great way to reduce emissions．Dockside residents will be encouraged to make use of a mini transit system and buy into the community's car share program．Finally，plans are under way for a high-tech heating system that will use renewable biomass instead of fossil fuels．
