What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart diseases, cancer, and aging itself, will become distant memory.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on---in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future.

People have wondered for a long time how their personalities and behaviors are formed．It is not easy to explain why one person is intelligent and another is not, or why one is cooperative （合作的）and another is competitive．
Social scientists are, of course, extremely interested in these types of questions．They want to explain why we possess certain characteristics and exhibit certain behaviors．There are no clear answers yet, but two distinct schools of thought （学派）on the matter have developed．As one might expect, the two approaches are very different from one another, and there is a great deal of debate between proponents of each theory．The controversy（argument) is often referred to as“nature and nurture（教育）”．
Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological and genetic factors．That our environment has little, if anything, to do with our abilities, characteristics, and behavior is central to this theory．Taken to an extreme(走极端）, this theory maintains that our behavior is predetermined to such a degree that we are almost completely governed by our instincts（本能）．
Proponents of the “nurture” theory, or, as they are often called, behaviorists, claimed that our environment is more important than our biologically based instincts in determining how we will act．A behaviorist, B．F．Skinner, sees humans as beings whose behavior is almost completely shaped by their surroundings．The behaviorists’ view of the human being is quite mechanistic（机械论的）; they maintain that, like machines, humans’ respond to environmental stimuli（刺激） as the basis of their behavior．
Socially and politically, the consequences of these two theories are far-reaching．In the US, for example, blacks often score below whites on standardized intelligence tests．This leads some proponents to conclude that blacks are genetically lower in status than whites．Behaviorists, on the contrary, say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy, and that, as a result, they do not develop the same responses that whites do．
Either of these theories cannot yet fully explain human behavior．In fact, it is quite likely that the key to our behavior lies somewhere between these two extremes. That the controversy will continue for a long time is certain．This passage is mainly concerned with．
| A．relation between personality and behavior |
| B．relation between behavior and environment |
| C．different accounts of patterns of human behavior |
| D．different theories of the formation of human behavior |
The underlined word " proponents'' in paragraph 2 means．

| A．the considerable（值得考虑的） influence of the two theories |
| B．differences between the blacks and whites |
| C．racial discrimination in the United States |
| D．different responds to intelligence tests |
What's the author's purpose in writing the passage?
| A．To call our attention to the changes of human behavior． |
| B．To urge scientists to do more research in social science． |
| C．To give us a detailed explanation of human behavior． |
| D．To present an argument in the field of social science． |
A new generation addiction is quickly spreading all over the world. Weboholism, a twentieth century disease, affects people from different ages. They surf the net, use e-mailand speak in chat rooms. They spend many hours on the computer, and it becomes a compulsive habit. They cannot stop, and it affects their lives.

As we drove off from Columbia, I wanted to write a letter to you to tell you all that is on my mind.
First, I want to tell you how proud we are. Getting into Columbia is a real testament（ 证明）of what a great well-rounded student you are. You should be as proud of yourself as we are.
Your college years will be the most important of your life. It is in college that you will discover what learning is about. This will be the period when you go from teacher-taught to master-inspired, after which you must become self-learner. So do take each subject seriously, and even if what you learn isn’t extremely impotant for your life, the learning skills you gain will be something you will cherish（怀念） forever.
Follow your passion in college. Take courses you think you will enjoy. Don’t be trapped by what others think or say, but make up your own mind.
Most importantly, make friends and be happy. College friends are often the best in life. Pick a few friends and become really close to them – pick the ones who are sincere and honest to you. Don’t worry about their hobbies, grades, looks or even personalities.
Start planning early – what would you like to do? Where would you like to live? What would you like to learn? I think your plan to study fashion is good, and you should decide where you want to be, and get onto the right courses.
Whether it is summer-planning, or coursework planning, or picking a major, or managing your time, you should take control of your life. I will always be there for you, but the time has come for you to be in the driver’s seat – this is your life, and you need to be in control. Being in control feels great. Try it, and you’ll love it!
College is the four years where you have:
lThe greatest amount of free time

A gentle breeze blew through Jennifer’s hair. The golden red sun was setting. She was on the beach, looking up at the fiery (火红的) ball. She was amazed by its color, deep red in the middle, softly fading into yellow. She could hear nothing but the waves and the seagulls flying up above in the sky.
The atmosphere relaxed her. After all she had been through, this was what she needed. “It’s getting late,” she thought, “I must go home. My parents will be wondering where I am.”
She wondered how her parents would react when she got home after the three days she was missing. She kept on walking, directing herself where she spent every summer holiday. The road was deserted. She walked slowly and silently. Just in a few hundred meters she would have been safe in her house.
It was really getting dark now. The sun had set a few minutes before and it was getting cold too. She wished she had her favorite sweater on: it kept her really warm. She imagined having it with her. This thought disappeared when she finally saw her front door. It seemed different. Nobody had taken care of the outside garden for a few days. She was shocked: her father was usually so strict about keeping everything clean and tidy, but now... It all seemed deserted. She couldn’t understand what was going on.
She entered the house. First, she went into the kitchen where she saw a note written by her father. It said: “Dear Ellen, there is some coffee ready. I went looking.” Ellen was her mother but — where was she? On the right side of the hallway was her parents’ room. She went in. Then she saw her. Her mother, lying on the bed, was sleeping. Her face looked so tired, as if she hadn’t slept for days. She was really pale. Jennifer would have wanted to wake her up but she looked too tired. So Jennifer just fell asleep beside her. When Jennifer woke up, something was different... she wasn’t in her mother’s room and she wasn’t wearing the old clothes she ran away in. She was in her cozy bed in her pajamas (睡衣).
It felt so good being back home. Suddenly she heard a voice, “Are you feeling better now, dear? You know you got us very, very scared.”The writer describes the beautiful sunset to show Jennifer’s ______.
| A．love of the natural beauty |
| B．desire of getting back home |
| C．intention of becoming independent |
| D．depression of being alone |

| A．The idea of going back home. |
| B．Her anxiety about her parents. |
| C．The feeling of being warm in her favorite sweater. |
| D．The feeling of getting back home safely. |

| B．he had to look after his wife |
| C．he was not strict with his job |
| D．he no longer enjoyed working in the garden |
We might like to think we're not influenced by other people, but a new study into the group-buying mechanisms（机制） - like those used on coupon（优惠券） sites such as Groupon and LivingSocial - reveals that telling buyers who come later to the offer how many have already signed up increases the number of purchasers.
Researchers at the University of Toronto's Rotman School of Management wanted to understand why group buying sites that have entered the market recently have enjoyed greater success than those operating a decade ago, such as Mercata and MobShop.
Earlier attempts typically left potential buyers waiting for days before confirming whether or not they had got the offer they had signed up for.
“We think one of the reasons group-buying has been successful recently is because of the short time horizon,” says Rotman Professor Ming Hu, who co-wrote the study with Professor Mengze Shi and PhD student Jiahua Wu. “It allows for a herding effect.”
Another reason is the use of an information structure that discloses to later arrivals how many have already signed onto the deal.
Researchers looked at two ways of designing the purchasing mechanism for a group buy:a simultaneous mechanism, where no one knows how many buyers have come before them, and asequential（连续的） mechanism, where a second group of buyers has the advantage of knowing the size of the first group.
The researchers' analytical（分析的） model shows the most successful mechanism is the sequential one because it eliminates uncertainty for those coming later to the deal, and improves the confidence of those who sign on early, as they're able to track the numbers of those who come after them.
“That boosts confidence,” says Professor Hu, who teaches operations management. Deals for "luxury" services, versus everyday items, work better in a group buy scenario（方案） because they offer consumers a greater benefit.It can be learned from the text that ______.
| A．the short time horizon is the reason why group-buying has been successful. |
| B．a simultaneous mechanism is where a group of buyers has the advantage of knowing how many people have signed up. |
| C．a sequential mechanism allows a herding effect which boosts the confidence of the buyers. |
| D．researchers at the University of Toronto's Rotman School of Management carried out an experiment about why group buying sites entered the market successfully, such as Mercata and MobShop. |
The underlined word “eliminates” in paragraph 7 probably means“______”.
| A．to become or to make something greater in amount, number, value |
| B．to remove or get rid of something |
| C．to deliberately not include something in what you are doing or considering |
| D．to make something known to somebody |
What can be the best title for the passage?
| A．Secret for marketing success – boosting confidence. |
| B．Secret for group-buying mechanism—herding effect. |
| C．Comparison between a simultaneous mechanism and a sequential mechanism. |
| D．What others do influences our decisions. |
