1 Human beings are born with this ability.2 ，experiment s 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 not3 . However, if you remove two, the bird4 leaves. This mean s that the bird knows the5 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 not7 until the man left the tower. The man had an8 . He took another man with him to the tower. One man left and the other stayed, but they did not9 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 were11 . It was not until five men went into the tower and only four left that they were12 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 go es beyond three or four, the children are14 fooled.It seems that number sense is something we have in common with many animals in this world, and that our human15 is not much better than a crow's.语法填空One day, Nick invited his friends to supper. He was cooking some delicious food in the kitchen. Suddenly, he 16 (find) that he had run out of salt. So Nick called to his son, “Go to the cillage and buy some salt, but pay a fair price for it : neither too much 17 too little.”His son looked surprised. “I can understand why I shouldn’t pay too much, Father, but if I can pay less, 18 not save a bit of money?”“That would be a very19 (reason) thing to do in a big city, but it could destroy a small village like outs,” Nick said.Nick’s guests,20 had heard their conversation, asked why they should not buy salt more cheaply if they could. Nick repli ed, “ The only reason a man would sell salt 21 a lower price would be because he was desperate for money. And anyone who took advantage of that situation would be showing a lack of respect22 the sweat and struggle of the man who worked very hard to produce it.”“But such a small thing couldn’t 23 (possible) destroy a village.”“In the beginning, there was only24 very small amount of unfairness in the world, but everyone add ed a little , always25 (think) that it was only small and not very important , and look where we have end ed up today.”Imagination and fantasy can play an important role in achiev ing the things we fear. Children know this very well.Fred Epstein, in his book If I Make It to Five, tells a story he heard from one of friends about Tom, a four-year-old boy with a cancer in his back bone. He came through several operation s and a lot of pain by master ing his imagination.Tom loved to pretend, and he particularly loved to play superheroes, Dr Epstein expained that it was actually a brilliant way for his yound mind to handle the terrifying and painful life he led.The day before his thire trip to the operating room, Tom was terribly afraid.“Maybe I could go as Superman,” he whisper ed to his mom.Hearing this, the moter hesitate d for a while. She had avoid ed buying the expensive costume(戏装)，but finally she agreed.The next day Tom appeared as the powerful Superman, show ing off through the hospital hall s and coolly waving his hand to the people greet ing him along the way. And Tom, with the strength of his fantasy, successfully made it(做到) through the operation.The power of imagination need not be reserve d 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(正如…说的) , “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 test ed 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(敢) to dream.【】26.What do we know about Tom?A.He was serious ly illB.He was a dishonest boy.C.He was crazy about magicD.He was Dr.Epstein’s patient【】27.What can be infer red about Tom’s mother?A.She was a rich ladyB.She refused Tom’s requestC.She wanted Tom to be a superheroD.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 spirit s(精神)D.argue d with his mother【】29.

I’m not going to sa y luck, talent, and circumstance s don’t come into play(起效) because they do. some people are born into the right family while others are born with great intelligence, and that’sjust 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, t ime 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 exhibit ing some great skills or having achieve d 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 are not willing to put in the time and work, don’t expect to receive any reward s.

How could I help him? There are problems psychology doesn’t have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetical lyThe first two times we met, David didn't say a word. He sat there, only look ing up to look at the children's drawings on the wall behind me. I suggested we play a game of chess. He nod ded. 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 set ting them up before I even got a chance to sit down.It seemed as if he enjoyed my company(陪). But why did he never look at me?“Perhaps he simply needs someone to share his pain with,” I thought.“Perhaps he sense s 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(沟通) another person.All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.【】36.
