Eye Problems1Our eyes are under a great deal of strain these days as computer work,television viewing,night driving,and even sunshine are making exceptional demands.Sunlight,especially in the summer,is now regarded as one cause of cataracts(白内障).2The thinning of the ozone(臭氧)layer means more short-wave ultraviolet(UV)rays(紫外线)are reaching the earth,and these are the biggest risk factor for clouding the lens of the eye.Ultraviolet rays increase the risk of changes to the cornea(角膜)causing clouded vision and eventually cataracts.The rays can be shielded only by anti-UV lenses. However,our eyes are not sufficiently protected by fashion sunglasses.3"Poor night vision and eye fatigue are noticeably more common,and there has been a big increase in minor eye complaints in the over-40s,"says Dr.Mireille Bonnet,who took part in recent research.She says that the six muscles controlling each eye move more than100,000times a day and thateveryone should learn to exercise their eye muscles and allow them to rest.4It was traditionally thought that near-or far-sightedness were inherited conditions and could not be influenced by environmental factors,but new research is challenging this assumption.5Recent studies suggest that up to80percent of schoolchildren in the United States and western Europe are nearsighted.Years of focusing on close,two-dimensional work causes most children to become at least slightly nearsighted by the age of10,say the researchers.6Problems with night vision,which affect around25 percent of people,are also on the increase because of computer ing computer screens means the eye ate in electromagnetic fields(Iti.111;*)that make work harder It is estimatedthamr;s5t30wino,'or people have eye Conditions. such as difficulty with night visiOn,which It from staring ata screen.23.Paragraph2____B____24.Paragraph3____A____25.Paragraph5____D____26.Paragraph6____E____A.The development of poor night visionB.The greatest threat to the eyesC.The function of sunglassesD.The reason for children’s nearsightednessE.The effects of computer on the eyesF.The ways to reduce eye complaints27.Sunlight in the summer is believed to be one cause of ___B___.28.We can wear anti-UV glasses to protect___D____.29.We used to believe that near-or far-sightedness were inherited from___A___.30.Over25%of people are estimated to have difficulty with night vision due to___E___.A.our parentsB.clouded visionC.eye musclesD.our eyesputer useF.eye move。

What We Take from and Give to the SeaAs long as we have been on earth,we have used the sea around us.We take from the ocean,and we give to it.We take fishes from the ocean--millions of kilograms of fish,every year,to feedmillions of people.We even use their bones for fertilizer.We take minerals from the ocean.One way to get salt is to place seawater in a shallow basin and leave it until it evaporates.Along with salt,other minerals are left after evaporation.Much gold and silver drift dissolved in the waters of the sea,too1.But the sea does not give them upby simple evaporation.Other gifts from the sea are pearls, sponges and seaweed.Pearls become jewelry.Natural sponges become cleaning aids.Seaweed becomesfood of many kinds一even candy,and ice cream—aswell as medicine.Believe it or not,fresh water is another gift from the sea.We cannot drink ocean water.Some of its contents may cause illness.But ocean water becomes fresh water when the salts areremoved.In the future,we will find ourselves depending more and more on fresh water from the sea.The sea gives us food,fertilizer,minerals,water,and other gifts.What do we give the sea?Garbage.We pollute the ocean when we use it as a garbage dump.Huge as it is,the ocean cannot hold all the water that we pour into it.Dumping garbage into the ocean is killing off sea life.Yet as the world population grows,we may need the sea and its gifts more than ever.We are finally learning that if we destroy our seas,we might also destroy ourselves.Hopefully,it is not too late.51A feed B attract C save D affect52A buy B treat C have D use53A flow B place C pour D throw54A before B until C after D for55A up B in C away D over56A Such B All C Another D Other57A change B become C make D turn58A material B item C product D food59A source B gift C thing D matter60A cure B cause C experience D catch62A costing B working C paying D depending63A gives B gets C teaches D pbtains64A if B when C although D because65A Reducing B Collecting C Removing D Casting。
Do You Have a Sense of Humor?Humor and laughter are good for us.There is increasing evidence that they can heal us physically,mentally,emotionally,and spiritually.In fact,every system of the body responds to laughter in some positive,healing way.So how can we get more laughter into our lives?(46)Psychologist and author,Steve Wlison,has some answers.Many peoplebelieve that we are born with a sense of humor.They think,“either you've got it,or you don't”Dr.Wilson points out that this false.(47)The parts of brain and central nervous system that control laughing and smiling are mature at birth(48)(After all,when a baby laughs,we don't rush over and say,“That kid has a great sense of humor!”)A sense of humor is something that you can develop over a lifetime.Sometimes people think that they don't have a good sense of humor because they are not good joke tellers.Dr.Wilson reminds us that telling jokes is only one of many ways to expresshumor.(49)Then we will make others laugh,too.A person who has a true sense of humor is willing and able to see the funny side of everyday life.One of the best definition of a sense of humor is“the ability to see the nonserious element in a situation.”Consider this sign from a sore window.“Any faulty merchandise will be cheerfully replanced with merchandise of equal quality.”The store manager probably placed the sign in the window to impress customers with the store's excellent service.(50)As Dr.Wilson says,“a good sense of humor means that you don't have to be funny;you just have to see what's funny.”A He advises us to lose our inhibitions(抑制)and try to laugh at ourselves.B Is it possible to develop a sense of humor?C However,that does not mean that infants have a sense of humor.D What is true,however,it that we are born with the capacityto laugh and smileE Everyone experiences this emotionF He had a serious purpose,but if you have a sense of humor,you will probably find the sign funny!答案:BDCAF。
Better Control of TB Seen If a Faster CureIs FoundThe World Health Organization1 estimates that about one-third of all people areinfected with bacteria that cause tuberculosis .Most times, the infection remains inactive. Buteach year about eight million people develop active cases of TB, usually in their lungs.Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis.Current treatments take at least six months. People have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure for tuberculosis would be more effective. Now a study estimates just how effective it might be. A professor of international health at Harvard University2led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others.The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. And it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve.The World Health Organization reductions the DOTS3program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment.Earlier this year, an international partnership oforganizations announced a plan to expand theDOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance for TB Drug Development4 says its long-term goal is a treatment that could work in as few as ten doses.A Biological Cloc kEvery living thing has what scientists call abiological clock that controls behavior. The biological clock tells (plants)when to form flowers and when the flowers should open. It tells (insects)_ when to leave the protective cocoons and fly away,and it tells animals and human beings when to eat, sleep and wake.Events outside the plant and animal _(affect)_ the actions of some biological clocks. Scientists recently found, for example, that a tiny animal changes the color of its fur _(because of)_ the number of hours of daylight. In the short _(days)__ of winter, its fur becomes white. The fur becomes gray brown in color in the longer hours of daylight in summer.Inner signals control other biological clocks. German scientists found that some kindof internal clock seems to order birds to begintheir long migration _(.flight)_ twice each year.Birds __(prevented from)__ flying becomerestless when it is time for the trip,_(but)__they become calm again when the time of theflight has ended.Scientists say they are beginning to learn which_(parts)__ of the brain contain biological clocks.An American researcher, Martin Moorhead, saida small group of cells near the front of the brain_(. seems)_ to control the timing of some of ouractions. These _(cells)_ tell a person when to _(awaken)_ ,when to sleep and when to seekfood . Scientists say there probably are otherbiological clock cells that control other bodyactivities.Dr. Moorhead is studying _(how)_ ourbiological clocks affect the way we do our work.For example, most of us have great difficulty ifwe must often change to different work hours._(It)_ can take many days for a humanbody to accept the major change in work hours.Dr. Moorhead said industrial officials shouldhave a better understanding of biological clocksand how they affect workers. He said _(such)_understanding could cut sickness and accidentsat work and would help increase a factory’sproduction,One Good Reason to Let Smallpox LiveIt’s now a fair bet that we will never see thetotal extinction of the smallpox virus. The ideawas to cap the glorious achievement of 1980,when smallpox was eradicated in the wild, bydestroying the killer virus in the last two labsthat are supposed to have it—one in the US andone in Russia. If smallpox had truly gone fromthe planet, what point was there in keeping thesereserves?in reality, of course, it was naive to imaginethat everyone would let go of such a potentialweapon. Undoubtedly several nations still havea few vials. And the last “official” stocks of licevirus bred mistrust of the US and Russia, for noobvious gain.Now American researchers have found ananimal model of the human disease, opening theway for tests on new treatments and vaccines.So one again there’s a good reason to keep thevirus—just in case the disease puts in areappearance.How do we_deal with the mistrust of theUS and Russia? Simple Keep the virus underinternational auspices in a well-guarded UNlaboratory that’s open to all countries. The USwill object, of course, just as it rejects amultilateral approach to just about everything.But it doesn’t mean the idea is wrong. If thevirus is useful, then let’s make it the servant ofall humanity—not just a part of it.Diet, Alcohol Linked to Nearly One Third ofCancersDiet is second only to tobacco as a leadingcause of cancer and, along with alcohol, isresponsible for nearly one third of cases of thedisease in developed countries, a leadingresearcher said on Tuesday.Dr. Tim Key, of the University of Oxford,told a cancer conference that scientists are stilldiscovering how certain foods contribute tocancer,but they know that diet, alcohol andobesity . play a major role.“Five percent of cancers could be avoidedif nobody was obese,” he said.While tobacco is blinked to about 30percent of cancer cases, diet is involved in anestimated 25 percent and alcohol in about sixpercent.Obesity raises the risk of breast, womb,bowel and kidney cancer, while alcohol isknown to cause cancers of the mouth, throatand liver, Its dangerous impact is increasedwhen combined with smoking.Key told the meeting of the charityCancer Research UK that other elements ofdiet linked to cancer are still unknown butscientists are hoping that the EPIC study,which is comparing the diets of 500,000people in 10 countries and their risk of cancer,will provide some answers Early results ofthe study have revealed that Norway, Swedenand Denmark have the lowest consumption offruit and vegetables among Europeancountries while Italy and Spain have thehighest. Eating at least five portions of fruitand vegetables a day is recommended toreduce the risk of cancer.Key, principal scientist on the EPICstudy, said it is looking at dietary links tosome of the most common cancers includingcolorectal, breast and prostate.Men Too May Suffer from DomesticViolence(2013已考)Nearly three in 10 men have experiencedviolence at the hands of an intimate partnerduring their lifetimes, according to one of thefew studies to look at domestic violenceand health among men."Many men actually do experience domesticviolence, although we don't hear about itoften," Dr. Robert J. Reid of the University ofWashington in Seattle, one of the study'sauthors, told Reuters Health. "They often don'ttell __ and__ we don't ask. We want to get themessage out to men who do experiencedomestic violence that they are not alone andthere are resources available to them "The researchers asked study participants aboutphysical abuse and non-physical abuse ,such as threats that made them fear for theirsafety, controlling behavior (for example,being told who they could associate with andwhere they could go), and constantname-calling.Among men 18 to 54 years old, 14.2 percentsaid they had experienced intimate partner__violence in the past five years, while 6. 1percent reported domestic violence in theprevious year.Rates were lower for men 55 and older,with5.3 percent reporting violence in the past fiveyears and 2.4 percent having experienced it inthe past 12 months.Overall, 30.5 percent of men younger than 55and 26.5 percent of older men said they hadbeen victims of domestic violence at somepoint in their lives. About half of the violencethe men experienced was physical.However, the physical violence men reportedwasn't as harsh as that suffered by women ina previous study; 20 percent to 40 percent ofthe men rated it as severe, compared to 61percent of womenMen who reported experiencing domesticviolence had more emotional and mentalhealth problems than those who had not,especially older men, the researchers found.。
