阅读下面短文，掌握其大意，然后从1~15各题所给的A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。
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.

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.
36. When he first met the author, David .
A. felt a little excited
B. walked energetically
C. looked a little nervous
D. showed up with his teacher
37. As a psychologist, the author .
A. was ready to listen to David
B. was skeptical about psychology
C. was able to describe David's problem
D. was sure of handling David's problem
38.David enjoyed being with the author because he________.
A.wanted to ask the author for advice
B.need to share sorrow with the author
C.liked the children’s drawings in the office
D.bear the author many times in the chess game
39.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.

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. 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 just searched the Internet to get the right answers.
Although online classes have existed for more than a decade ，the concern over cheating has 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 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.
41. Why was Jennifer watched in anonine exam ?
A.To correct her typing mistakes.
B.To find her secrets in the room.
Cto prevent her form slowing down.
D.To keep her from dishonest behaciors.
42. The underlined expression cutting edge in Paragraph 3 is closest in meaning to ______.

44.Some programs can find out possible cheaters by _____.

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.

参考范文
It is reported that thirty volunteers to be sent to the Mars who are at least 18 years old will be chosen from all the globe by the year of 2015. The volunteers must make a full preparation that there is almost no chance to return to the earth once they are immigrated to the Mars. What’s more, it is greatly important for them to try to keep a good relationship with other members. Experts strongly warned that the living conditions on the Mars are very hard, for not only the extremely cold climate would they meet with, but also loneliness and fear. On the contrary , the volunteers insist that they have got tired of the life on the earth, so greatly being eager to experience the unknown , mysterious life on the Mars; meanwhile, if the would be succeeded , they would get the honor to be heroes of human beings.
第二节：读写任务
In the passage, the author mainly stressed the importance of small and ordinary work , such as cleaning the street because of their essentiality重要性;本质;真髓;根本性for the organization of the society ,and thinks those doing such jobs should be respected greatly.
There is no doubt that what a cleaner does is more harder compared with any other jobs in the society. On one hand, they must get up in the early morning every day to clean the street while we are sill in the sweet sleeping dreams. On the other hand, they also suffer from less respect and lower pay, working all day on the street no matter it is sun shines strongly or snow, wind heavily.
Nobody could imagine what an bad environment we would live in if there were no cleaners in the city. Wherever we go, there is rubbish. Maybe we would soon be drowned in the mountain of rubbish. Even worse, if there were no change about that, diseases would spread at a very quick speed. Is there anything that can be worse than this!
From the above, I can draw the conclusion safely that even the smallest and the most ordinary job, such as cleaning the street is also the necessary part to keep the society going smoothly. Consequently, those who do those most insignificant微不足道的jobs should get respected as much as those being engineers or doctors.
答案解析：
1. C 由下文的两个实验来看，都是数理的“变化”。其他三个选项“上升”“样式”“趋势”与文中内容几乎毫无关系。
2. B
因“实验表明许多动物也跟人类一样具有这种能力”，这是“令人惊讶的”。其他选项“重要地”“失望地”“幸运地”与上下文内容无联系。
3. D
结合下句，特别是however可知，上下句的大意应是“如果鸟巢内有四个蛋，你移走一个蛋，这只鸟会没有注意到;然而，如果你移走两个蛋，这只鸟就会离开这里了”。其他选项“幸存”“关心”“
孵化”不合语境。
4. A 把这只鸟“通常”会离开，因为这个具体的例子是用来说明“many birds have good number
sense”这个主题的。“真诚地”“无意地”“故意地”不合语境。
5. C
这个例子谈到，四个中移走一个余下三个，这只鸟会注意不到;若移走两个，余下两个了，这只鸟就会离开这里了。这说明这只鸟知道余下两个与余下三个的“差别”。其余选项“距离”“范围”“间隔”与语境不符。
6. A 与上文中good number
sense(良好的数字感)中的good相对应，也与第2题的答案surprising相对，故选“amazing
(令人惊异的)”，近义复现。其他选项“讨厌的”“令人满意的”“ 烦扰的”不合语境。
7. D 与left相对，“离开”“返回”这两者也叫同现;与下文中return to the
nest的return是原词复现。
8. C 从下文看，这个人有了一个“主意”或想了一个“办法”。 其他选项“约会”“借口”“解释”均不合语境。
9. A 由but可知，他们并没能“欺骗”那只乌鸦。与下文fool the
crow中的fool是原词复现，也就是说从此可以得到启示。
10. B
该实验由一个人去接近那只乌鸦，然后带一个人即一共两个人去做这个实验，接着三个人、四个人去“重复”做这个实验。其他选项“报告”“设计”“证明”均现语境不符。
11. B 那只乌鸦直到所有人都“不见了，消失了”才会回来。
12. D
前面已分别由一个人、二个人、三个人、四个人重复做了四次了，直到五个人进了塔，只走了四个，即还有一个在塔里，他们才“最终”欺骗了这只乌鸦。结合文章倒数第二段讲14个月的婴儿在超过三四个之后就常常被欺骗，就可理解了，当数字超过一定数量后就可欺骗了。
13. B 由下文But when the number goes beyond three or
four可知，是指三四个以内的这样一“小”组东西。
14. D 由but可知，后文是表示与always
notice相对的意思，当数理超过三四个以后，就“常常”能欺骗这些婴儿了。其他选项“很少”“
暂时地”“只是”与语境不符。
15. C
由文章的首段或首句可知，本文在讲到人具有数字感的同时，重点是讲动物的数字感，即有辨别数字变化的“能力”。
16. found 在主格人称代词he后应为谓语动词，由语境可知用一般过去时。
17. nor 构成并列连词neither…nor。
18. why 因why not do sth (何不做某事)?是固定句式。
19. reasonable 在名词前作定语要用形容词。
20. who 引导非限制性定语从句，并在从句中作主语，先行词是人，故填who。
21. at 因名词a low price在句中不作主语、动词的宾语，应为介词的宾语;根据习惯搭配，用介词at。
22. for 固定搭配show respect for表示“尊重”。
23. possibly 修饰谓语动词作状语，用副词。
24. a 因a small amount of(少量的)是固定搭配。
25. thinking 因everyone与think是主动关系，故用现在分词短语作added的伴随状语。
26. A 细节题。由第一段最后一句He came through several
operations and a lot of
pain可知，他病得很严重，故选。选项B(他是一个不诚实的孩子)和选项C(他对魔术着了迷)都是无中生有;由第一段第三句Fred
Epstein, in his book If I Make It to Five, tells a story he
heard from one of his friends about Tom可知，有关Tom的事情是Dr.
Epstein从他的一个朋友那里听来的，因此可排除选项D(他是Dr. Epstein的病人)。
27. D 推断题。由第三段第三四句Hearing this, the mother hesitated for a
while. She had avoided buying the expensive costume(戏装), finally
she
agreed.可知，她并不富有，但最终还是同意了Tom的请求，为他购买昂贵的'戏装，由此推断，她是希望Tom能度过痛苦关。由had
avoided buying the expensive costume可排除选项A;由finally she
agreed可排除选项B;她同意为他购买昂贵的戏装其目的不是希望他真正成为超人，故排除选项C。
28. B 细节题。由第四段第一句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可知，他的行为就像是一个超人。
29. C
细节题。由最后一段的第一句可排除选项D;选项A(经历一些困难的测试)和B(从不羁梦中醒来)含文中的一些字眼，其实是断章取义;由第三句Become
the person you need to become to win over your challenge and do it
in your mind first可知，选项C(要成为一个内心强大的人)正确。
30. D 目的题。由文章首句Imagination and fantasy can play an
important role in achieving the things we fear.可全文末句So, let your
imagination run wild, and dare to
dream可知，作者写这篇文章的目的是鼓励我们运用我们的想象力。
31. A
段意归纳题。文中的“运气”“天赋”“家庭环境”等都是指成功的条件或理由，故选A。本段中并没有讲什么是成功，排除选项B(成功的含义)和C(成功的标准);也没讲成功对人生有哪些重要性，也容易排除选项D。
32. B 代词指代题。代词是意义衔接的手段之一，此处的代词that替代前句中的set a goal and then
gradually make it more practical，故选B。
33. D 细节理解题。题眼出现在第三段第一句This is a big reason why many successful
people advise you to do something you
love.但其中的this就是指代上文的内容，即第二段的第后两句话的内容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，这两句就告诉我们，要成功需要花费大量的时间。
34. C 推理判断题。由第一句they have put in a huge part of their life to
get there at a huge cost可推知。
35. C 主旨归纳题。由第二段开头的However可知，本文的中心论题不是第一段而在第二段to succeed in
life, one first needs to… needs to…，再结合最后一段第一句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，可知本文的主题思想是不花时间和实践是不可能取得成功的。
36. C 推理判断题。因David失去了家人，怎么可能兴奋呢?可排除选项A;由He kept walking up and
down restlessly, his face pale, and his hands shaking
slightly(他烦躁地地走来走去，面色苍白，双手在微微地颤抖)可推断，他进来时有点紧张，故选C，在这种情况下他不可能是“精神抖擞地走进来”，文中也没有相应的信息说明这一点，可排除选项B;由His
head teacher had referred him to
me中的时态可知，老师将David的情况告诉作者是在David进来之前，且由he
wrote可知，是老师写的字条而不是亲自来了，故排除选项D。
37. A 细节理解题。由第二段How could I help him? There are problems
psychology doesn’t have the answer to, and which no words can
describe
(我应如何来帮助他呢?这些是在心理学上没有答案的难题;也是用语言无法描述的难题)可排除选项D(有把握处理David的问题)和C(能够描述David的问题);选项B只是使用了文中psychology这个词，其实文中根本没有表明“作者怀疑心理学”的信息，只是说明心理学上没有处理David这类问题的现存答案，故排除B;由第二段最后一句Sometimes
the best thing one can do is to listen openly and
sympathetically可知，选A，作者打算倾听David。
38. B 细节理解题。第四段告诉我们David喜欢跟作者在一起，第五段中作者的推测Perhaps he simply
needs someone to share his pain with. Perhaps he senses that I
respect his suffering可知，选B。
39. A 推理判断题。从第六、七、八段的叙述，即从Some months
later至Now he had really started to
live his own
life可以推断，David恢复了，故选A。选项B和D若正确，就会有朋友同David分担悲伤了，也就没有必要来同作者下棋了，故也可排除。
40. D 细节理解题。由第三段中的After that he played chess with me every
Wednesday afternoon一in complete silence and without looking at
me和最后一段第二句But I also learned that one一without any words一can reach
out to another person可知，选D，是作者同David的无声交流改变了David。
41. D 推理判断题。由第三段第一句In the battle against
cheating可知，前面两段对Jennifer在家考试中受监控器的监控的具体描述是为了防止他作弊。
42. A 词义推断题。由第二段的具体描述来看，这是防止作弊的先进技术，另外，也可以从第五段的第一句中的other
high-tich
methods(另外的高科技方法)得到启示，要选A。其他选项“磨锐刀具”“有效的规则”“分界线”都不合语境。深圳网 www.szcnn.com dongding
43. B 细节理解题。由第三段最后一句Only with solid measures against cheating,
experts say, can Internet universities show that their exams and
diplomas are valid可知，只有有了打击作弊的强有力的措施，网络大学才能表明他们的考试和文凭是有效的。
44. A 细节理解题。由最后一段第二句recognize possible cheaters by analyzing
whether difficult test questions are answered at the same speed as
