It is the ability to recognize a 1 in number. Human beings are born with this ability. 2 ,experiments show that many animals are, too. For example, many birds have good number sense. If a nest has four eggs and you remove one, the bird will not 3 . However, if you remove two, the bird 4 leaves. This means that the bird knows the 5 between two and three.Another interesting experiment showed a bird's 6 number sense. A man was trying to take a photo of a crow(乌鸦)that had a nest in a tower, but the crow always left when she saw him coming. The bird did not 7 until the man left the tower. The man had an 8 .He took another man with him to the tower. One man left and the other stayed, but they did not 9 the bird. The crow stayed away until the second man left, too. The experiment was 10 with three men and then with four men. But the crow did not return to the nest until all the men were 11 .It was not until five men went into the tower and only four left that they were 12 able to fool the crow.How good is a human's number sense? It's not very good. For example, babies about fourteen months old almost always notice if something is taken away from a 13 group. But when the number goes beyond three or four, the children are 14 fooled.It seems that number sense is something we have in common with many animals in this world, and that our human 15 is not much better than a crow's.1.

2013 年普通高等学校招生全国统一考试(广东卷)英语第一节完型填空Number sense is not the ability to count.It is the ability to recognize a 1 in number.Human beings are born with this ability. 2 ,Experiments show that many animas are,too.For example,many birds have good number sense.If a nest has four eggs and you remove one,the bird will not 3 .However,if you remove two,the bird 4 leaves.This means that the bird knows the 5 between two and three.Another interesting experiment showed a bird’s 6 number sense.A man was trying to take a photo of a crow(乌鸦) that had a nest in a tower,but the crow always left when she saw him coming.The bird did not 7 until the man left the tower.The man had an 8 .He took another man with him to the tower.One man left and the other stayed,but they did not 9 the bird.The crow stayed away until the second man left,too.The experiment was 10 with three men and then with four men.But the crow did not return to the nest until all the men were 11 .It was not until five men went into the tower and only four left that they were 12 able to fool the crow.How good is a human’s number sense? It’s not very good.For example,babies about fourteen months old almost always notice if something is taken away from a 13 group.But when the number goes beyond three or four,the children are 14 fooled.It seems that number sense is something we have in common with many animals in this world,and that our human 15 is not much better than a crow’s.1.A.rise B.pattern C.change

situation would be showing a lack of respect 22 the sweat and struggle of the man who worked very hardto produce it.”“But such a small thing couldn’t 23 (possible) destroy a village.”“In the beginning,there was only 24 very small amount of unfairness in the world,but everyone added a little,always 25 (think) that it was only small and not very important,and look where we have ended up today.”第三节阅读理解AImagination and fantasy can play an important role in achieving the things we fear.Children know this very well.Fred Epstein,in his book I Make It to Five,tells a story he heard from one of his friends about Tom,a four-year-old boy with a cancer in his back bone.He came through several operations and a lot of pain by mastering his imagination.Tom loved to pretend,and he particularly loved to play superheroes.Dr.Epstein explained that it was actually a brilliant way for his young mind to handle the terrifying and painful life he led.The day before his third trip to the operating room,Tom was terribly afraid.“ Maybe I could go as Superman,” he whispered to his mom.Hearing this,the mother hesitated for while.She has avoided buying the expensive costume(戏装),but finally she agreed.The next day Tom appeared as the powerful Superman,showing off through the hospital halls and coolly waving his hand to the people greeting him along the way.And Tom,with the strength of his fantasy,successfully made it through the operation.The power of imagination need not be reserved for children only.We all have the power to use our fantasies to attempt things we never thought possible,to go through those things that seem impossible,and to achieve what we never believed we could.Just as Dr.Epstein puts it,“If you can dream it,you can do it.”It doesn’t mean that you should dress as a superhero for your next job interview.But,next time you are tested in a way that seems impossible,imagine what it would take to overcome it.Become the person you need to become to win over your challenge and do it in your mind first.So,let your imagination run wild,and dare to dream.26.What do we know about Tom?A.He was seriously ill.B.He was a dishonest boy.C.He was crazy about magic.D.He was Dr.Epstein’s patient.27.What can be inferred about Tom’s mother?A.She was a rich lady.B.She refused Tom’s request.C.She wanted Tom to be a superhero.D.She wanted to get Tom through the pain.28.When Tom went for the third operation,he _______.A.pretended to be painfulB.acted like a superheroC.appeared in poor spiritsD.argued with his mother29.In the last paragraph,you are advised _______.A.to go through some difficult testsB.to wake up from your wild dreamsC.to become a powerful person in your mindD.to wear expensive clothes for job interviews30.What is the purpose of the passage?A.To tell us an interesting story.B.To help us make right decisions.C.To advise us to care about children.D.To encourage us to use our imagination.BSome people think that success is only for those with talent or those who grow up in the right family,and others believe that success mostly comes down to luck.I’m not going to say luck,talent,and circumstances don’t come into play becau se they do.Some people are born into the right family while others are born with great intelligence,and that’s just the reality of how life is.However,to succeed in life,one first needs to set a goal and then gradually make it more practical.And,in addition to that,in order to get really good at something,one needs to spend at least 10,000 hours studying and practicing.To become great at certain things,it’ll require even more time,time that most people won’t put in.This is a big reason why many successful people advise you to do something you love.If you don’t enjoy what you do,it is going to feel like unbearable pain and will likely make you quit well before you ever become good at it.When you see people exhibiting some great skills or having achieved great success,you know that they have put in a huge part of their life to get there at a huge cost.It’s sometimes easy to think they got lucky or they were born with some rare talent,but thinking that way does you no good,and there’s a huge chance that you’re wrong anyway.Whatever you do,if you want to become great at it,you need to work day in and day out,almost to the point of addiction,and over a long period of time.If you’re not willing to put in the time and work,don’t expect to receive any rewards.Consistent,hard work won’t guarantee you the level of success you may want,but it will guarantee that you will become rally good at whatever it is you put all that work into.31.Paragraph 1 mainly talks about _______.A.the reasons for successB.the meaning of successC.the standards of successD.the importance of success32.Paragraph 2,the underlined word that refers to _______.A.being good at somethingB.setting a practical goalC.putting in more timeD.succeeding in life33.Successful people suggest doing what

people like to show their great skills.B.People sometimes succeed without luck or talent.C.People need to achieve success at the cost of life.D.It helps to think that luck or talent leads to success.35.What is the main theme of the passage?A.Having a goal is vital to success.B.Being good is different from being great.C.One cannot succeed without time and practice.D.Luck,talent and family help to achieve success.COne day,when I was working as a psychologist in England,an adolescent boy showed up in my office.It was David.He kept waling up and down restlessly,his face pale,and his hands shaking slightly.His head teacher had referred him to me.“This boy has lost his family,” he wrote.“He is understandably very sad and refuses to talk to others,and I’m v ery worried about him.Can I help?”I looked at David and showed him to a chair.How could I help him? There are problems psychology doesn’t have the answer to,and which no wards can describe.Sometimes the best thing one can do is to listen openly and sympathetically.The first two times we met,David didn’t say a word.He sat there,only looking up to look at the children’s drawings on the wall behind me.I suggested we play a game of chess.He nodded.After that he played chess with me every Wednesday afternoon - in complete silence and without looking at me.It’s not easy to cheat in chess,but I admit I made sure David won once or twice.Usually,he arrived earlier than agreed,took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down.It seemed as if he enjoyed my company.But why did he never look at me?“Perhaps he simply needs someone to share his pain with,” I thought.“Perhaps he senses that I respect his suffering.” Some months later,when we were playing chess,he looked up at me suddenly.“It’s your turn,” he said.After that day,David started talking.He got friends in school and joined a bicycle club.He wrote to me a few times,about his biking with some friends,and about his plan to get into university.Now he had really started to live his own life.Maybe I gave David something.But I also learned that one — without any words — can reach out to another person.All it takes is a hug,a shoulder to cry on,a friendly touch,and an ear that listens.36.When he first met the author,David _______.A.felt a little excitedB.walked energeticallyC.looked a little nervousD.showed up with his teacher37.As a psychologist,the author _______.A.was ready to listen to DavidB.was skeptical about psychologyC.was able to describe David’s problemD.was sure of handling David’s problem38.David enjoyed being with the author because he _______.A.wanted to ask the author for adviceB.needed to share sorrow with the authorC.liked the children’s drawing in the officeD.beat the author many times in the chess game39.What can be inferred about David?A.He recovered after months of treatment.B.He liked biking before he lost his family.C.He went into university soon after starting to talk.D.He got friends in school before he met the author.40.What made David change?A.His teacher’s help.B.The author’s friendship.C.His exchange of letters with the author.D.The author’s silent communication with him.DWhile Jennifer was at home taking an online exam for her business law class,a monitor(监控器) a few hundred miles away was watching her every move.Using a web camera equipped in Jennifer’s Los Angeles apartment,the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room.Her Internet access was locked —remotely —to prevent Internet searches,and her typing style was analyzed to make sure she was who she said she was; Did she enter her student number at the same speed as she had in the past? Or was she slowing down?In the battle against cheating,this is the cutting edge and a key to encourage honestly in the booming field of on line education.The technology gives trust to the entire system,to the institution and to online education in general.Only with solid measures against cheating,experts say,can Internet universities show that their exams and diplomas are valid---that students haven’t searched the Internet to get the right answers.Although online classes have existed for more than a decade,the concern over cheating become sharper in the last year with the growth of “open online courses.” Private colleges,public universities and corporations are jumping into the online education field,spending millions of dollars to attract potential students,while also taking steps to help guarantee honesty at a distance.Aside from the web cameras,a number of other high-tech methods are becoming increasingly popular.Among them are programs that check student’s identities using personas information,such as the telephone numbers they once used.Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at he same speed as easy ones.As in many university classes,term papers are scanned against some large Internet data banks for cheating.41.Why was Jennifer watched in an online exam?A.To correct her typing mistakes.B.To find her secrets in the roomC.To prevent her from slowing down.D.To keep her from dishonest behaviors42.The underlined expression cutting edge in Paragraph 3 is closest in meaning to _______.A.advanced techniqueB.sharpening toolC.effective ruleD.dividing line43.For Internet universities,exams and diplomas will be valid if _______.A.they can attract potential studentsB.they can defeat academic cheatingC.they offer students online helpD.they offer many online courses44.Some programs can find out possible cheaters by _______.A.checking the question answering speedB.producing a large number of questionsC.scanning the Internet test questionsD.giving difficult test questions45.Which of the following is the best title of this passage?A.The Advantages of Online ExamsB.The High-tech Methods in Online CoursesC.The Fight against Cheating in Online EducationD.The War against the Booming of Online Education第四节信息匹配A.FREE HEALTH BOOKSVisit www.Health Book Summauies.com now for instant access to easy-to-read summaries of the top books on health,food and fitness emailed to you automatically,for FREE.Call Now 1-866-720-3880B.Ready to use straight from the pack; Low self discharge for long storage period.Super Durable Battery; Wide application range From digital cameras to clocks.C.Save GEICO Big savings look good on you.Find our how much you could be saving on an insurance visit geico.com,call 1-800-947-AUTO[2886],or contact your local GEICO office today.See geico.com for more details.D.FREE Home Security System! $850 value!

Number sense is not the ability to count. It is the ability to recognie a 1 in number. Human b eings are born with this ability. 2 ,eperiments show that many animals are, too.For eample, many birds have good number sense. If a nest has four eggs and you remove one,the bird will not 3 .However,if you remove two, the bird 4 leaves. This means that the bird nows the 5 between two and three.Another interesting eperiment showed a bird's 6 number sense. A man was trying to tae a photo of a crow(乌鸦)that had a nest in a tower, but the crow always left when she saw him coming. The bird did not 7 until the man left the tower. The man had an 8 .He too another man with him to the tower. One man left and the other stayed, but they did not 9 the bird.The crow stayed away until the second man left, too. The eperiment was 10 with three men and then with four men. But the crow did not return to the nest until all the men were 11 .It was not until five men went into the tower and only four left that they were 12 able to fool the crow.How good is a human's number sense? It's not very good. For eample, babies about fourteen months old almost always notice if something is taen away from a 13 group.But when the number goes beyond three or four, the children are 14 fooled.It seems that number sense is something we have in common with many animals in this world,and that our human 15 is not much better than a crow's.1.A. rise B. pattern C. change D. trend2.A.
