阶段测试(一)Ⅰ.阅读理解㈠阅读理解AThe first day of school our professor challenged us to get to know someone we didn’t know.I turned around to find a wrinkled(有皱纹的) old lady.She said,“Hi,handsome.My name is Rose.I’m 87 years old.Can I give you a hug?”I laughed and enthusiastically responded,“Of course you may!”,and she gave me a giant squeeze.“Why are you in college at such an old age?”I asked.I was curious what may have motivated her to be talking on this challenge at her age.“I always dreamed of having a college education and now I’m getting one!”she told me.After class we shared a chocolate milk shake.We became instant friends.Every day for the next three months,we would leave class together and talk non-stop.Over the course of the year,Rose became a campus star and she easily made friends wherever she went.At the end of the term we invited Rose to speak at our football banquet(宴会).I’ll never forget what she taught us.She cleared her throat and began,“We do not stop playing because we are old;we grow old because we stop playing.If you are 19 years old and lie in bed for one full year and don’t do one productive thing,you will turn 20 years old.If I’m 87 years old and stay in bed for a year and n ever do anything,I will turn 88.Anybody can grow older.That doesn’t take ant talent or ability.The idea is to grow up by always finding the opportunity in change and have no regrets.”At the year’s end Rose finished the college degree.One week after gradua tion,Rose died peacefully in her sleep.Over 2000 college students attended her funeral in honor of the wonderful woman who taught by example that it’s never too late to be all you can possibly be.1.Where did the author first got to know Rose?A.In a café.B.In class.C.At a banquet.D.In the library.2.What did Rose want to do through her speech?A.Express gratefulness for her education.B.Share her ambition with others.C.Encourage her college mates.D.Show her speaking skills.3.What does the author think of Rose?A.Energetic and caring.B.Positive and admirableC.Curious an friendlyD.Innocent and enthusiastic.4.Which can be the best title for the text?A.A Forever FriendB.Memory of College LifeC.We All Grow OlderD.Never Too Late to Pursue DreamsBEver feel like you’ve been hit on the head after a bad night’s sleep?According to scientists,the thought is n’t as far-fetched as it seems.A study found going without sleep for just one night causes changes in the brain similar to those that occur after a blow to the head.Professor Christian Benedict,of Uppsala University,Sweden,explained that the chemicals NSE and S-100B are biomarkers for brain damage.He said:“What we found was that their levels in the blood rose in the group that went without sleep for a night.This was not to the extent that would happen after a head injury,for instance,but it was still significant.During sleep,the brain cleans itself of toxic substances and NSE and S-100B increase in response to there substances.”He said the findings back up previous research showing how the brain uses sleep to clean itself.Professor Benedict said his study could also support previous studies which linked lack of sleep with increased risk of Alzheimer’s disease,Parkinson’s disease and Multiple sclerosis.The rise of the chemicals in the blood after sleep loss may suggest not getting enough sleep is conducive to a loss of brain tissue, explained.Professor Benedict,whose study is published in the journal Sleep,added:“In conclusion,the findings of our trial indicate a good night’s sleep may be critical for maintaining brain health.”A third of the UK population suffer from sleep-related problems,while the average person now sleeps for only seven hours a night,compared with almost nine a few decades ago.Many scientists believe irregular sleeping patterns lead to illnesses ranging from aches and pains to heart dis ease,while less than eight hours’ sleep a night can lower the IQ the next day.And more and more scientists have offered many different ways to get a good night’s sleep.1.The underlined phrase in Paragraph 3 probably means“”.A.supportB.objectC.reflectD.drag2.According to the passage,what can we infer from the study?A.A good night’s sleep can’t decrease the risks of many diseases.B.A good night’s sleep makes no difference to our health.C.The longer we sleep,the better our body becomes.D.A good night’s sleep benefits our brain health.3.What may the passage talk about next?A.The reasons why the research began.B.The disadvantages of a poor night’s sleep.C.The diseases linked to a poor night’s sleep.D.The advice on how to get a good night’s sleep.4.What is the best title of the passage?A.The Background of a Research on Sleep and Our BrainsB.The Findings of a Research on Sleep and Our BrainsC.The Effect of a Good Sleep on Our Brains.D.The Importance of a Good Sleep.CGretchen Alexander is sightless.But she refuses to allow her blindness to limit her life activities.She enjoys archery,golf,softball,sailing and water skiing,as well as a number of other activities that those of us who are sighted have yet to learn.She also speaks to groups about living life fully.When speaking to a group of high school students,she was once asked if there was anything she wouldn’t try.“I’ve decided never to try skydiving,”she answered.“It would scare me to de ath.”Why do some people rose above their problems and live life fully,while others become defeated?Merle Shain explains it this way:“There are only two ways to approach life:as a victim or as a gallant fighter.And you must decide whether you want to act o r to react.”When discourages,a victim reacts,perhaps in pain or self-pity.But a fighter will act.A fighter will make a decision to change that set of circumstances that leave him or her discouraged.Or a fighter will decide to accept those circumstances with grace and move ahead anyway.A fighter will decide to act with courage.A fighter will take responsibility for his or her happiness.No matter how afraid,a fighter will refuse to give in to the most defeating of all humanemotions—helplessness.A victim rea cts.A fighter acts.To be a victim or a fighter it’s your decision.It’s a decision about whether you will lie you life fully with courage,or you will be forever defeated by harsh circumstances.Make it well,for it may be one of the most important decisions you ever make.Will you be a victim or a gallant fighter?1.What can we learn about Gretchen Alexander from this passage?A.She is more athletic than whose of us who are sighted.B.She is discouraged when her dog is scared.C.There is no limitation to her life activities.D.She is a brave fighter.2.The underlined word “it” in Paragraph 3 is closest in meaning to “”.A.lifeB.choiceC.courageD.circumstance3.The third paragraph mainly talks about .A.the difference between a victim and a fighterB.The reactions to helplessnessC.Decision-makingD.A fighter’s responsibility4.The best title for this passage would be .A.Gretchen Alexander’s LifeB.Merle Shain’s Attitude to LifeC.Victims and fightersD.The Way of LifeDWe’re often told to “eat a rainbow”and we aim for the guideline that says the more color a food has,the better it is.However,color is just one indicator of nutrient.Produce that wears white could be just as valuable.In fact,some white vegetables contribute substantial quantities of nutrients that we seem to be missing most often,also known as shortfall nutrients,like potassium(钾),magnesium(镁) and fiber.MushroomsMushrooms are low in calories,fat-free,cholesterol-free,gluten-free,with barely any sodium(钠),and yet they carry a wealth of selenium,potassium,riboflavin(核黄素),niacin and vitamin D.Mushrooms are also hearty and filling so they can help you control your weight.They can help simple dishes come alive.GarlicAside from tasting great,garlic has been regarded as being able to help hair grow,cause acne to disappear and keep a cold and the flu away.Its antioxidant properties can help strength your immune system,and to get the most out of garlic’s act ive chemical—allicin,cut a clove of garlic up and expose it to the air for a while before you cook with it.OnionsChef Julia Child said,“I cannot imagine a world without onions,”and for good reason.The anti-inflammatory(消炎的)chemical in onions,called quercetin,can help ease discomfort from arthritis,and quercetin’s beneficial properties have been associated with a lower risk of cancer,heart disease,diabetes and a stronger immune system.PotatoesNearly all Americans fail to meet dietary recommendations for potassium(97 percent) or dietary fiber (95 percent).On an equal weight basis,the white potato provides as much fiber as andmore potassium than other commonly consumed vegetables or fruit.Potatoes also provide vitamin C,vitamin B6 and magnesium,in addition to small amounts of high-quality protein.1.According to the passage,which of following doesn’t belong to shortfall nutrients?A.CalciumB.FiberC.MagnesiumD.Potassium2.If you are losing weight,it is effective to have .A.mushroomsB.garlicC.onionsD.potatoes3.Before cooking,cut garlic up and expose it to the air in order to .A.get riboflavinB.taste deliciousC.get allicinD.decrease the risk of cancers4.What similarity do garlic and onions have according to the passage?A.They can help hair grow.B.They can keep colds and flu away.C.They can help ease discomfort.D.They can strengthen your immune system.㈡阅读七选五Ways to Improve Your MemoryHuman mind is remarkable thing.In many ways we could consider it the original super computer ,capable of astonishing feats when it’s wo rking optimally.Some of the secrets of getting the most out of our minds are quite simple to carry out once we are aware of them. 1 Check out these ways to improve your memory,and you may never find yourself wondering where you left your car keys again!Cut Stress. 2 This means when anyone with these things is running wild in your life,your memory will suffer,sometimes greatly.Some methods that have worked again and again:meditation,yoga or even spending relaxing time with a pet. 3Get Blood Flowing.Exercise isn’t only great for your body,but it’s equally good for your long and short term memory. 4 Then what you thought was a bad memory will likely be replaced by a more youthful mind that is less forgetful.So running,swimming,riding a bike or clocking in on the rowing machine are all good choices here.5 This is a trick used by all of the world’s top memory contest winners,so you know that if we accept it we should take it very seriously!Instead of thinking of words and numbers when we try to remember something,make an effort to think in visual terms.By associating what we would like to remember with images,we are much,much more likely to remember what we wish to without struggling.It’s a law of how our minds work that can be easily used to impro ve our memories in seconds.Get in the habit of drawing pictures in your mind and a memory contest may be in your near future too!A.Image Association.B.Eat more fish and legumes.C.Give these a try and see what you think.D.Have you even wished you memory?E.Get moving,and keep your blood flowing in a healthy manner consistently.F.In fact,not sleeping well one night can take a good night’s sleep to recover from.G.Depression,stress and anxiety all tax the same area of your brain that is responsible for memory.
