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 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.

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.”Ican understand why Ishouldn’t pay too much,Father,but if I can pay less, 18 not sace 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 shoule not buy sale more cheaply if they coule.Nick replied,”The only reason a man would sell sale 21 a lower price woule be because he wai desperate for money.And anyone who took adcantage of that situation woule be showing a lack of respect 22 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 only 24 very small amount of unfairness in the world,but everyone added a little ,always 25 (think) that it was only samall and not very important ,and look where we hace ended up today.”
Imagination and fantasy can play an important role in achiebving 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 operations and a lot of pain by mastering 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 terrbly afraid.”Maybe I could go as Superman ,”he whispered to his mom.Hearing this, the moter hesitated for a while.She had avoided buying the expensive costume(戏装)，不痛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 hace 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 you next job interview.But,next time you are texted in a way that seems impossible, imagine what it woule take to overcome it .Become the person you need to become to win over your challenge and do it in your maind first.So,let your imagination run wild,and dare to dream.

Some 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 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 ger 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 fo feel like unbearable pain and will likely make you quit well before you ever become good ai 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 really good at whatever it is you put all that work into.

One day, when I was working as a psychologist in England，an adolescent boy showed up in my office. It was David. He kept walking 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 very worried about him. Can you 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 words 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一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.
"Ifs 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一without any words一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.

While Jennifer was at hose 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 form 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 honesty in the booming field of online education.

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 camers, a number of other hight-tich methods are becoming increasingly popular Among them are programs that check students’ identities using personal information,such as the telephone number they once used.
Other programs can produce unique exam by drawing on a arge list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones ,As in many university classes ,term papers are scanned aganinest some large Internet data banks for cheating.

To many people even the word “work” sounds unpleasant ,not necessarily because they are lazy.The same man,who dislikes his job in the factory or even in the office ,may work hard at the weekend ,painting the house or digging the garden.
What is the reason ,then ？In most cases ,it is because these people simply do not enjoy the
Job they are doing .It does not give them any real satisfaction .It may be quite easy ,like making up wooden boxes ,but it is very boring.Very often they are doing a job which is just a small part of
a much larger one ,such as attaching a door handle to a car .But the part they play in actually making the car is so small that they can never say :I have made something !
Yet in modern society somebody has to do ordinary jobs such as cleaning streets because this
Is the way society is organized ,No matter how ordinary a job is, it plays a part in society and therefore deserves our due respect. Society cannot function a single day without the “dull and boring” jobs.
