19．Easy ways to get healthy
    I always hate the first few weeks of the new year，mostly because I-m sick to death of people in commercials who are all．"Let's diet!It's a new year!"
You can always choose to switch it up!（36）EHere are some simple ways to get your healthy on all year around．
Switch out bad habits for good ones．（37）GDo something as simple as swapping nighttime cookies for nighttime vitamins．
    Catch some sleep．One of the most important things we can do for our minds and bodies is to make sure．we're getting enough sleep on a regular schedule．（38）F     Feed your mind．Keep your mind flexible and smart．Do crosswords，sudoku（數(shù)獨）．Start a new hobby，read a book about something you don't understand-anything that challenges you to think differently and exercise that brain of yours．
    （39）AI'm not suggesting you take on a brand new fitness quest，but take the stairs，park farther away，and find a hobby you enjoy that allows you to be active．
Get organized．I'm not saying a whole repair of your entire world； start small．Organize a kitchen  cabinet．Purge （清除 ）yourself of stuff you  don't need．
     Get rid of the mess．That means your mind is included too!Make lists．Get a calendar and mark down important days．Clear your mind and your home．（40）C    
Smile．Overlook some of the bad things that are going on in your life．a(chǎn)nd focus on the good．There are positives in nearly every situation，even if it doesn't feel like it．Staying positive can help in nearly every aspect of your life!

A．Change your activity up．
B．Try exercising your brain too．
C．You'll find it improves your mood．
D．You are the one to improve yourself．
E．lt's time to take charge of your health!
F．Sounds boring，I know，but trust me---sleep is amazing for you．
C．Start small，and don't plan to change your entire life in a week．

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
26．According to Dr Kurt Straif，we can learn thatB．
A．the effect of the．smoggy weather is gradual
B．a(chǎn)ir pollution is the man environmental cause，of cancer deaths
C．exposure has greatly increased in countries with large populations
D．"feed people with smog"has bee a hot word
27．The purpose of this passage is toA．
A．a(chǎn)waken people's environmental awareness
B．warn people not to go out in smoggy weather
C．call for the public to wear their masks
D．a(chǎn)dvise people not to live in Harbin．

17．They already guide blind and disabled people； now dogs are to be trained to help people with dementia（癡呆） or Alzheimer's．Alzheimer's can make people confuse night and day or forget basic things such as washing or drinking enough water．
    The dogs will be trained to respond to sound triggers（觸發(fā)器） in the home that cause them to perform tasks．The duties will include reminding their owners to take medicine，as well as encouraging them to eat，drink and sleep regularly．
    The idea was developed by design students at the Glasgow School of Art and will now be put into practice by Alzheimer's Scotland and Dogs for the Disabled．The first dogs will be distributed to four Scottish couples，where one of the partners is in the early stages of dementia．Some 670，000 people in Britain have dementia and one in three over 65s will develop the condition．By 2021 this is expected to rise to one million．
    Joyce Gray of Alzheimer's Scotland said，"People in the early stages of dementia are still able to live a relatively normal life，and dogs help to maintain routine．"Another advantage of using the pets as companions is that dogs can give them a sense of silent support and companionship．Ms Gray said，"The evidence is that people may forget familiar faces but not pets．It's such a strong bond that people often remember them longest．People don't need to communicate verbally （言語地） but they can still interact．You can have a speechless bond．"
    Helen McCain，director of Dogs for the Disabled，said，"People with dementia often forget to take the medicine．If a dog presents them with a bag with pills in it there's a greater chance of them taking it．The dog would also encourage the owner to take them out for walks，ensuring they keep exercising and interacting with other people．"
32．In Britain people with dementiaA
A．a(chǎn)re likely to increase in number    
B．a(chǎn)re mostly over 65 years old
C．will be trained to respond to sound triggers

33．The dogs are taught to perform tasks byD．
A．making some sound signals  
B．communicating with the patients
C．reminding the patients by barking   
D．reacting to some sound triggers
34．What does the underlined word"them"in Paragraph 4 refer to？C   
A．Faces．          B．Triggers．      C．Pets．           D．Companions．
35．What is mainly talked about in the passage？B
A．The idea of dementia dogs was developed by students．
B．Dogs are trained to assist Alzheimer's patients．
C．British people with Alzheimer's are in poor condition．
D．The dementia dogs perform most duties of a doctor．

16．Scientists from the University of East Anglia have identified four new man-made gases that are contributing to the damage to the ozone（臭氧） layer．Two of the gases are accumulating at a rate that is causing concern among researchers．
Worries over the growing ozone hole have seen the production of chlorofluorocarbon （CFC） gases restricted since the mid 1980s．But the precise origin of these new，similar substances remains a mystery．
Lying in the atmosphere，the ozone layer plays a critical role in blocking harmful UV rays，which cause cancers in humans and reproductive problems in animals．
Scientists from the British Antarctic Survey were the first to discover a huge"hole"in the ozone over Antarctica in 1985．The evidence quickly pointed to CFC gases，which were invented in the 1920s，and were widely used in refrigeration．Extraordinarily，global action was rapidly agreed to deal with CFCs and the Montreal Protocol to limit these substances came into being in 1987．A total global ban on production came into force in 2010．
Now，the newly discovered four new gases can destroy ozone and are getting into the atmosphere from as yet unidentified sources．Three of the gases are CFCs and one is a hydrochlorofluorocarbon （HCFC），which can also damage ozone．
The research has shown that four gases were not around in the atmosphere at all until the 1960s，which suggests they are man-made．The scientists discovered the gases by analyzing polar snow pack．Air from this snow is a natural archive of what was in the atmosphere up to 100years ago．The researchers also looked at modern air samples，collected at remote Cape Grim in Tasmania．
They estimate that about 74，000tonnes of these gases have been released into the atmosphere．Two of the gases are accumulating at significant rates．However，they don't know where the new gases are being released from and this should be investigated．Possible sources include chemicals  for insecticide（殺蟲劑） production and solvents（溶液）  for cleaning electronic ponents．The three CFCs are being destroyed very slowly in the atmosphere-so even if emissions（散發(fā)） were to stop immediately，they will still be around for many decades to come．
Of the four species identified，CFC-113a seems the most worrying as there is a very small but growing emission source somewhere，maybe from agricultural insecticides．We should find it and take it out of production．

63．What do we know about the newly discovered gases？B
A．Some are surely produced by the development of agriculture．
B．The CFCs will have a long impact once they are released．
C．They gather together in the atmosphere at a medium speed．
D．Their amounts are not large enough to cause damage to us．
64．The underlined word"archive"in Paragraph 6is closest to the meaning of"D"
A．state          B．resource          C．phenomenon        D．storeroom
65．What will the scientists probably attempt to do about the gases next？C
A．Find out what can replace things like insecticides and put them into use．
B．Find out how they destroy ozone and get rid of those in the atmosphere．
C．Find out where they are exactly from and stop them from being released．
D．Find out if HCFC is more harmful than CFCs and take proper measures．

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？

14．One of the most important recent medical breakthroughs has been the impact of gut flora（腸道菌群）on overall health．This dynamic mix of bacteria in the digestive tract（消化道）may affect everything from obesity to asthma（哮喘）．
The Gut-Mood Link
Anyone who's ever experienced"butterflies"in his or her stomach knows that the gut and the brain are connected．But until recently，scientists hadn't realized that the trillions of bacteria in our digestive tract may be driving the relationship．
One recent experiment suggests that you can control calm．Canadian researchers gave healthy mice a mixture of antibiotics，which change the makeup of GI-tract（胃腸道）bacteria．Over two weeks，some animals became more anxious and some less，depending on which drugs they received．
In another study，when gut bacteria from calm mice were transferred to anxious mice，the jittery（緊張的）creatures seemed less nervous．
UCLA professor Kirsten Tillisch，doctor of medicine，recently had healthy women eat a yogurt rich in certain types of"good"probiotic（益生菌的）bacteria．Two'Control groups ate yogurt without such bacteria or ate nothing．Brain scans of the probiotic-yogurt eaters indicated changes in regions that could be associated with a less-anxious response in fearful or stressful situations compared with the control groups．
Scientists are even exploring whether gut microbes（微生物）might treat some brain disorders．
A new study in Cell found that mice with features of autism（自ICJ癥）given a type of bacteria in healthy human GI tracts exhibited less autism-like behavior．In a recent case report，a Boston ps} chiatrist says a course of certain probiotics and antibiotics helped relieve a patient's compulsive disorder．
-We tend to focus on how your mood affects your body from the top down，not the bottom up，"says Dr．Tillisch．"Now we know that the gut affects how your brain responds to the environment-it's a remarkable change in thinking．"
How Bacteria Talk to the Brain
Scientists aren't sure how gut flora affect brain chemistry．One theory is that the bacteria access pathways along the nerve，the main highway in the nervous system that links the brain to the gut．
Another is that the bacteria influence the immune system，releasing chemicals that affect conditions like depression．Finally，researchers believe that bacteria produce or affect the metabolism（新陳代'i） of chemicals，which change brain function．
Dr．Tillisch told me that patients always ask which probiotics will lift their mood．Her answer：
"We don't know yet，but we hope to one day．"In the future，patients might receive probiotics or transplant（移植） in which bacteria from the gut of a healthy person are transferred to the gut of a sic'：one-to prevent or treat mental health issues．But these approaches are years away from primary time．Until then，a diet rich in fruit and veggies helps cultivate（培養(yǎng)）better-balanced microbes than a typical Western diet high in animal and processed products．Avoiding unnecessary antibiotics，particularly in early childhood，may also establish healthier gut bacteria．

63．According to the passage，gut bacteria might help us in many ways EXCEPTD．
A．lightening our mood 
B．treating autism
C．relieving depression 
D．transplanting gut flora
64．The missing sentence"Everyday foods may also affect the composition of gut bacteria，and in turn，brain chemistry．"could be put beforeC•
A．Paragraph 2   B．Paragraph 3   C．Paragraph 4   D．Paragraph 5
65．Which of the following can be the best subtitle for the last paragraph？A
A．Cultivating a Happier Gut B．Growing Bacteria in the Future
C．Balancing Microbes and Diet D．Living a Happy Healthy Life．

13．It was a cold night in Washington，D．C．，and I was heading back to the hotel when a man approached me．He asked if I would give him some money so he could get something to eat．I'd read the signs："Don't give money to beggars as most of them are swindlers．"So I shook my head and kept walking．
I wasn't prepared for a reply，but with no hesitation，he followed me and said，"I really am homeless and I really am hungry!You can come with me and watch me eat!"But I kept on walking．
The incident kept bothering me for the rest of the week．I had money in my pocket and it wouldn't have killed me to hand over a dollar or two even if he hadn't been a real beggar．On a freezing cold night，no less，I assumed the worst of a fellow human being．
Flying back to Anchorage，I couldn't help thinking of him．I tried to reason my failure to help by supposing government agencies，churches and charities were there to feed him．Besides，you're not supposed to give money to beggars．
Somewhere over Seattle，I started to write my weekly garden column for The Anchorage Daily News．Out of the blue，I came up with an idea．Bean's Cafe，a local charity service kitchen，feeds hundreds of hungry local people every day．Why not try to get all my readers to plant one row of vegetables or flowers in their gardens for Bean's？Plant a row for Bean's．It's clean and simple．
We didn't keep records back then，but the idea began to take off．Folks would fax me or call when they took something in．It's food for the spirit and comfort for my conscience．
In April 1995，the Garden Writers Association of America（GWAA） held their annual meeting in Anchorage and after learning our program，Plant a Row for Bean's became Plant a Row For The Hungry．The idea then was to have every member write or talk about planting a row for the hungry，which brought the program to national attention．
As more and more people participated，new variations cropped up．Many companies gave free seeds to customers and displayed the logo for the program．Donations poured in．It was then that I could really stop feeling guilty．

66．The underlined word"swindlers"in the first paragraph is closest in meaning toC．
A．policemen
B．writers
C．cheaters
D．beggars
67．Why did the author think he assumed the worst of a fellow human being？B
A．Because he didn't show fair respect to a beggar treating him badly．
B．Because he could have helped a hungry man but he passed by．
C．Because he believed that no people begged because of real hunger．
D．Because he thought that charity work was the government's duty．
68．How did the author make up for what he had done？D
A．He set up a local kitchen to help the poor．
B．He planted a row of vegetables for charity．
C．He called on people to donate money to the Bean's．
D．He initiated the idea of Plant a row for Bean's．
69．Which of the following statements is TRUE according to the passage？C
A．The beggar gave up the first time he was turned down by the author．

C．GWAA expanded the program concept and made it nationwide in 1995．
D．The program was later taken over by some seeding companies．

12．All people need to sleep．Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life．Not only is the quantity of sleep important，but also the quality of sleep．
    Your bedroom should be shaped to your taste and allow you to sleep in a peaceful environment．One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep．If your bedroom also functions as a command station for your life and work，the likelihood of your sleeping being poor is rather high．Bedrooms should be designed，decorated and used for sleep mainly．TVs，computers and other things should not be in your bedroom if at all possible．
    Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness．Avoid hot food，caffeine，sugar and alcohol at least 4 to 6 hours before your sleep time．Develop a regular exercise program．Proper exercise and nutrition will help improve sleeping patterns．However，avoid exercising 2 hours before sleeping，since this may stimulate your body and make sleeping more difficult．
   Establish a pre-bedtime rule that will help you focus on sleep．You can try deep thought，reading or deep breathing and relaxation．Your bedtime rule should be yours．Do not worry about it fitting into a specific category．Do what is best for you．
Things such as room temperature，noise and light levels and even your bed mattress（床墊） can have a lot of effect on the quality of sleep that you experience．Block out distracting noises and lights．You are in your bedroom to sleep and not be distracted by environmental interferences．
