    9．For pet owners，the hundreds of pet food recalls taking place each year has raised a lot of alarm．"Most people are caring pet owners，and they want to do what helps protect their pet，"explains Will Post，founder and CEO，Hound & Gatos Pet Foods Corporation．"Yet the problem is that most are not sure what that means and how to go about it．The more they learn about pet food，the better able they will be to make an informed decision that will keep their pet healthier and safer．"
    Here are several tips that consumers may want to keep in mind when it comes to choosing a pet food that will help reduce the risks．
    Get to know the company．Most people may know a company name simply because they spend millions on advertising．But that doesn't mean they know much about the company or their morals．Research companies to find one that offers high standards，quality products，and great customer service．
    Ask questions．Don't be afraid to get in touch with a pet food company and ask them where something was made，where ingredients（原料） came from，or any other questions．They should have no problem answering questions about their products，or with being able to provide proof of their quality standards．
    Read reviews．Do some searches to read some reviews about various brands of pet food．Keep in mind that some reviews can be one-sided and even planted by the company itself，so look for fair third-party sources giving the review．
    Investigate（调查） ingredients．The source of ingredients is of major concern when it comes to reducing the risks of pet food recalls and keeping pets healthy．Read the labels and ask questions to determine where the ingredients are coming from．
    Understand pet foods．Cat and dog food should contain 100percent protein，which will supply them with the nutrients their bodies require．The problem with many commercial pet foods is that it is full of numerous fillers，such as cheap fillers and grains．

    36．How can people provide a safer and healthier environment for their pet？B
    A．By giving more food to their pet．
    B．By getting a better understanding about pet food．
    C．By accompanying their pet more．
    D．By knowing more about their pet．
    37．How many pieces of advice on choosing a pet food are given by the author？C
    A．Three．  B．Four．  C．Five．  D．Six．
    38．As for reducing the risks of pet food recalls，what should be mainly taken into consideration？A
    A．Where the ingredients come from．
    B．Whether the company has good reputation．
    C．Whether the food supply enough nutrients．
    D．Whether most people choose the food．
    39．The passage is mainly aboutB．
    A．the increasingly serious problem about food safety
    B．the ways to choose a safer pet food
    C．the opinion about food safety
    D．the advice on caring pets
    40．Who are the intended readers of the passage？D
    A．People in general．
    B．Food companies．
    C．Pet shop owners．
    D．Pet owners．

    20．The 11billion self-help industry is built on the idea that you should turn negative thoughts like"I never do anything right"into positive ones like"I can succeed．"But was positive thinking advocate Norman Vincent Peale right？Is there power in positive thinking？
    Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect：it can simply highlight how unhappy they are．The study's authors，Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick，begin by citing older research showing that when people get feedback which they believe is overly positive，they actually feel worse，not better．If you tell your dim friend that he has the potential of an Einstein，you're just underlining his faults．In one 1990s experiment，a team including psychologist Joel Cooper of Princeton asked participants to write essays opposing funding for the disabled．When the essayists were later praised for their sympathy，they felt even worse about what they had written．
    In this experiment，Wood，Lee and Perunovic measured 68students'self-esteem．The participants were then asked to write down their thoughts and feelings for four minutes．Every 15seconds，one group of students heard a bell．When it rang，they were supposed to tell themselves，"I am lovable．"
    Those with low self-esteem didn't feel better after the forced self-affirmation．In fact，their moods turned significantly darker than those of members of the control group，who weren't urged to think positive thoughts．
    The paper provides support for newer forms of psychotherapy （心理治疗） that urge people to accept their negative thoughts and feelings rather than fight them．In the fighting，we not only often fail but can make things worse．Meditation （静思） techniques，in contrast，can teach people to put their shortcomings into a larger，more realistic perspective．Call it the power of negative thinking．
    （Note：Answer the question or complete the statements in NO MORE THAN 12WORDS）

    78．The self-help industry is based onthe concept of positive thinking．
    79．The finding of the Canadian researchers is thatencouraging positive thinking many do more harm than good．
    80．From the experiment of Wood，Lee and Perunovic，we know thatforcing a person to think positive thoughts may lower their self-esteem．
    81．From the last paragraph，we know thatmeditation may prove to be a good form of psychotherapy．

    17．Fast food and too much TV time should not take all the blame for the weight problems．A group of researchers say that a number of aspects of modern living from lack of sleep to environmental chemicals and to living with air conditioning-may be closely related to the weight problems of many people．
    Lack of sleep is one of factors．Researches in animals and humans suggest that a lack of sleep over a long time can increase appetite．Studies also show that many adults and children are sleeping less than they used to．In recent decades，adults have gone from sleeping for all average of nine hours to about seven hours．
    There is also evidence that industrial chemicals may increase body fat．These chemicals，which are used in products，change hormonal（荷尔蒙的） activity when they get into the body．Studies suggest that people have been getting more and more of these chemicals through the food chain in recent decades．
    Another factor that may be making people overweight is air conditioning．The body burns calories when forced to eat less in hot and wet weather，but air conditioning makes it unnecessary for the body to make any adjustment．
    Researchers also list other possible risk factors for overweight，including more older mothers，whose children may become overweight more easily； a number of medicines which can lead to weight gain； and fewer people who smoke，since people often gain weight when they stop smoking because nicotine can make people eat less．
    No one is suggesting that people should stop working and sleep more，or keep smoking．When it comes to saying any person's weight，what really matters is how much they eat and how much of the food they use every day．That means diet and exercise are still the key．

    81．Why does lack of sleep will result in weight problem？（No more than 5words）Because it can increase appetite．
    82．How long do adults averagely sleep nowadays？（No more than 2words）Seven/7 hours．
    83．How do the industrial chemicals affecting our weight come into our body？
    （No more than 4words）Through the food chain．
    84．What is the main idea of this passage？（No more than 18words）A number of aspects of modern living may be closely related to the weight problems of many people．

    4．The Ebola Virus
    Currently，the world is facing an epidemic （流行病） due to what is considered to be among the most dangerous viruses that humanity has ever faced-the Ebola bleeding virus．Though there were announcements about experimental treatments that were reported to be successful in terms of treating the virus，people around the world continue to die from Ebola．
    Ebola was first discovered in 1976in Africa，on the banks of the Ebola River，after which the virus has been named．Back then，there were two major outbreaks of the virus，and this is how people learned about it．There exist several strains of the Ebola virus，some of them are deadly to people，and some are not．
    The main symptoms of Ebola can appear in a period between the second and the 21st days of infection，but usually it happens on the eighth through 10th day．Among the symptoms that appear in the first turn，one should mention fever and chills，strong headaches，pain in joints and muscles，and general weakness．These symptoms are not too different from those that people usually experience when catching a severe cold，or flu，so victims may even ignore these symptoms，or try to treat them as a common sickness．However，as the virus keeps progressing，a patient develops nausea（呕吐） with vomiting，diarrhea，chest and stomach pains，red eyes and rash over the body，severe weight loss，and bleeding from almost all bodily openings．
    The virus is usually transmitted either through blood，or through waste．Infection through blood usually takes place if a person consumes infested meat，or even touches it （for example，butchering can also lead to infection）．Also，there were cases when people got infected after stepping in waste of infected mammals，mostly bats．The other ways of getting infected is through skin by receiving bodily liquids via tiny openings．
    Even though there is no specific cure for Ebola，doctors still try to treat it．In order to diagnose Ebola，doctors usually take tests on such diseases as cholera or malaria，because it is difficult to diagnose Ebola based only on symptoms．After the diagnosis has been made，doctors start treating the symptoms，which includes killing infected cells，electrolytes，blood pressure medication，blood transfusions，oxygen treatment，and so on．
    Though Ebola is a highly dangerous disease，it is not likely that it will spread globally．It is most deadly in anti-sanitary（不卫生的） conditions，which many African countries have an extremely bad reputation for．As for first world countries，even though there is still no universal cure，they are at much lesser risk than African countries．Though the symptoms of Ebola are severe and getting infected is not difficult，with the correct handling of an outbreak，the virus should not be able to spread．


    （71）Introduction    		●Ebola，a dangerous virus，was named after the Ebola River，on whose banks it was first discovered．
    ●Despite the （72）announced/reported success in the virus treatment，people across the world continue to die from the virus．

    Symptoms    		●In the first turn，the symptoms are （73）similar to those that people experience when they are （74）suffering from a severe cold or flu．
    ●If not （75）taken seriously，the virus will keep progressing，and things will change for the worse．

    Ways of getting infected    		●People （76）consuming infested meat or touching it can get infected．
    ●People who step in waste of infected mammals，mostly bats，are （77）likely to get infected．
    ●People who receive bodily liquids via tiny openings can also get infected．

    Treatment and  （78）prevention    		●After making correct diagnosis，doctors start treating the symptoms in many ways，（79）including killing infected cells，blood pressure medication，oxygen therapy，and so on．
    ●Sanitary living conditions play a significant （80）part/role in preventing the outbreak of the Ebola virus．

    14．There's nothing like a good night's sleep-but what does that really mean？It turns out that the answer depends not only on your age，but also on your lifestyle．Some people are productive and happy with fewer hours of sleep，while others need more．Still，experts can determine guidelines that work for most people．The National Sleep Foundation researched the topic and gave new recommendations this week．The foundation acknowledges that sleep needs will vary-lifestyle and stress should be taken into consideration-but their recommendations offer a general guideline．For example，teenagers （ 14-17 years old） ne 8-10 hours，sleep every day．
    To create the recommendations，some sleep and medical experts reviewed 312 articles from journals published during the last decade．This is the first time that any professional organization has developed age-specific recommended sleep durations based on a systematic review of the world scientific literature．
    A lack of sleep can be linked to weight gain，because that causes an increase in appetite，according to the foundation．It can also have serious consequences on the brain．People who d o not get enough sleep are at increased risk for depression，and can endanger others．Those that become sleepy while driving，for example，risk both their lives and the lives of those around them．
    Researchers also have found in the past that too much sleep can have negative effects．Low socioeconomic status and depression reportedly are significantly associated with longer sleep．However，experts nowadays find that research on oversleeping is still unconvincing and needs more attention．Currently，there is no strong evidence that sleeping too much has health consequences．There is，however，laboratory evidence that short sleep durations of four to five hours have negative consequences．We need similar laboratory studies to determin e whether long sleep durations result in physiological changes that could lead to disease before we make any recommendations against sleep extension．
     
    41．Which is TRUE about sleeping time？A
    A．The time you need for sleep is related to your state of mind．
    B．Experts'guideline for sleeping time applies to all the people．
    C．The less you sleep，the more productive you are．
    D．The more you sleep，the more energetic you are．
    42．How did die National Sleeping Foundation do the research？B
    A．By interviewing different people．B．By reading lots of articles．
    C．By consulting other experts．D．By doing systematic experiments．
    43．The research shows that people without enough sleep willB
    A．lose some weight                                       
    B．eat more food  
    C．dream during their sleep                             
    D．drive faster than usual
    44．From Paragraph 4，we can learn thatC．
    A．too much sleep may result in social changes   
    B．researchers now agree with those ill the past
    C．more research on oversleeping is needed      
    D．research on oversleeping is quite convincing
    45．From which section of a newspaper is the passage most probably taken？A
    A．Health
    B．Psychology    
    C．Sport
    D．Education．

    1．After hours sitting inside Deep Worker，it feels good to get back．While you're stretching on the deck，others on the ship are at work studying the data you have collected．
    The rock samples you collected are taken to a laboratory on board the ship．Tests performed on ocean rocks can show the age of the seafloor．Many people will study the videotapes of the swordfish．There is nothing like a video to show others exactly what you saw and experienced in the deep．Videos capture details of how animals move and behave-details that a person sitting inside Deep Worker could easily miss．Those details can help scientists better understand the role each kind of animal plays in its deep-sea community．
    While you were below，Deep Worker's exact location was being tracked．Thus，detailed maps of the seafloor，showing underwater canyons and mountains far beneath the surface can be made with the help of this information．Dive by dive，Sylvia Earle and her fellow scientists are piecing together remarkable pictures of the deep sea-a world that until recently was as unknown as a distant planet．
    Since Sylvia first began exploring the waters around Florida，she's seen changes-trash on the seafloor，fewer fish，polluted water．These ocean problems in Florida and in many other parts of the world make people like Sylvia anxious．They want to know how to protect the ocean，and how to restore it to good health where damage has been done．
    Sylvia and other scientists are learning more about the ocean，especially the deep sea，than ever before．The more we know about a place，the better we understand it．As Sylvia says，"With knowing comes caring．If people care about something，they will work to protect it．"
    66．What does the bold-typed phrase"this information"in Paragraph 3 refer to？D
    A．The location of underwater canyons and mountains．
    B．Remarkable pictures of the deep sea．
    C．These ocean problems．
    D．The track of Deep Worker．
    67．Sylvia Earle is probably a scientist whoB．
    A．specializes in making maps
    B．cares about the ocean
    C．works on an unknown ship
    D．performs experiments in a laboratory
    68．According to Paragraph 4，which statement about Sylvia is TRUE？SylviaBA．has seen fewer fish and polluted water 
    B．is concerned about the ocean problems
    C．has explored the waters and protected the ocean
    D．has restored good health after her injury
    69．Which of the following might be the best title of the passage？D
    A．Working below in Deep Worker
    B．Ocean Exploration and Ocean Maps
    C．Deep Worker Saving the World 
    D．Ocean familiarity and Ocean Preservation．

    18．Smoggy weather has become common in China．But these days，air pollution levels in the north eastern city of Harbin surpassed the previous record levels．
    The city was essentially shut down after PM2.5，fine Particulate（微粒物） pollution that is considered hazardous（有害的）．reached levels of 1000micrograms per cubic meter-40times the safety level remended by the World Health Organization．Schools，motorways and an airport were closed on Tuesday as visibility in some areas of the city dropped to less than 10meters．
    Photos from Harbin showed residents covering their mouths with masks and scarves，and moving like ghostly shadows through the fog．Cars and motorcycles are moving slowly as traffic came to a standstill with traffic lights barely visible．．
    Just days previously，the World Health Organization's International Agency for Research on Cancer （IARC）  classified air pollution as a carcinogen（致癌物）．It stated that there  is"sufficient evidence"that exposure to outdoor air pollution causes lung cancer and also linked it with an increased risk of bladder cancer．It's said that exposure has increased significantly particularly in"rapidly industrial countries with large populations"．
    "The air we breathe has become polluted with a mixture of cancer-causing substances"，Dr Kurt Straif，head of the IARC said in a press released．"We now know that outdoor air pollution is not only a major risk to health in general，but also a leading environmental cause of cancer deaths．"
    On the Chinese social media site Weibo，many users complained about the pollution and shared their concerns．References to"feed people with smog"have become popular on Weibo and there is a sarcastic play on the expression"serve the people"，as the two have a similar pronunciation．
    "The impact of air pollution on people will be gradual．There won't be a sudden outbreak of symptoms，but normally three to five days after the smoggy weather occurs，there is a peak in the number of people seeing doctors，"Deng Ying，a doctor at the Second Affiliated Hospital of Harbin Medical University was quoted as saying．

    24．As thick smog has become a common scene in Harbin，D
    A．students there can go to school as usual
    B．residents in the city can see as far as 20meters
    C．traffic lights can be easily visible
    D．the urban traffic has been seriously influenced
    25．When exposed to outdoor air pollution，what kind of disease can be caused？C．
    A．Cancer of stomach  B．Breast cancer  C．Bladder cancer     D．Ovarian cancer

    11．Going on holiday not only makes you feel good while you're there，you also gain the health benefits for months，new research shows．
    Jetting off to destinations such as the Maldives cuts your blood pressure，helps you sleep better and bounce back from stress，it found．The benefits last at least a fortnight longer than the vacation and can be felt for months in some cases where it is claimed．Experts say workers should always take their full holiday entitlement（权利）each year，but as many as one in three don't．
    The study compared key health markers in holidaymakers visiting Thailand，Peru or the Maldives，with people who stayed at home and continued working．The average blood pressure of those on holiday dropped by six percent while the workers saw their blood pressure rise by two percent over the same period．The sleep quality of holidaymakers improved by 17 percent while that of the non-holidaymakers deteriorated by 14 percent．
    The study also found the ability of vacationers to recover from stress，known as the stress-resilience test improved by 29 percent．There was a 71 percent fall in stress resilience scores among workers．Tests showed a fall in blood glucose levels，reducing the risk of diabetes （糖尿病），trimmer waistlines and improved mood and energy levels，with the effects sustained for at least two weeks after returning home．
    The Holiday Health Experiment was conducted by tour operator Kuoni and Nuffield Health，the UK's largest healthcare charity．
