The Segway Human Transporter was invented by Dean Kamen.It is a two-wheeled vehicle designed for a single rider standing upright over its single axle(軸) and navigate using a set of handlebars resembling those on a bicycle.Electrically powered, it could travel over 15 miles on a single charge and reach speeds up to twelve miles per hour.Its speed and direction can be controlled by riders' changing their weights.
A college dropout and self-taught engineer, Kamen already held over 100 patents for his inventions when he developed the one he hoped would revolutionize short-distance travel.While still in college, Kamen started developing the medical devices (設(shè)備) that made his name.Later, he changed focus to the challenges faced by wheelchair users.His robotic wheelchair known as IBOT could climb stairs.This robot ended up paving the way for the Segway.
Before showing his most recent invention, Kamen had kept it a top secret for months.When it turned out to be little more than a motor scooter, many publicly expressed their disappointment.On closer examination, however, even his critics(批評家) had to admit that the vehicle was an engineering achievement.It answered the prayers of anyone who is worn out when walking downtown.Not everyone welcomed the Segway's arrival, though.Some complained it was too expensive, while others said it would further weaken the average American ' s fitness.A Japanese inventor even accused Kamen of stealing the idea for the Segway from him.
Despite the controversy, the U.S.postal service began using Kamen's invention a month after its appearance, and a factory was built with plans to produce about 40,000 Segways every month.The argument is still on whether the Segway will be remembered as the greatest invention since the light bulb, or just another forgettable electronic device.Anyway, trips to the local supermarket will never be the same again.
小題1:Which statement best describes the critics' reaction to the Segway?
A.Nothing but an electrical device.
B.A disappointing engineering mistake.
C.An expensive and disappointing invention.
D.Disappointing, but still a successful device.
小題2:Which is not a feature of the Segway?
A.One person at a time can ride on it.
B.It has two wheels with a single axle.
C.It is powered by electricity and can go up to 12mph.
D.Riders increase the speed by moving the handlebars
小題3:Some people expressed dissatisfaction with the Segway because of its______.
A.high costB.danger to traffic
C.being difficult to useD.contribution to laziness
小題4:Shortly after the Segway appeared, there were _________.
A.hopes for a larger model of it
B.no plans to do anything more with it
C.some discussions on the unforgettable device
D.plans to make tens of thousands of them a month

小題1:D
小題2:D

Every electronic gadget (小玩意) needs good memory. A music player stores songs, albums and playlists. A computer holds schoolwork and programs and remembers how far a player has advanced in his or her favorite game. Mobile phones store names, numbers and hundreds of texts.
Now, scientists in California say they have come up with a way to turn a living cell into a memory device.
It can store only one tiny bit of information, but it’s a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease.
Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can’t be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream.
If normal machines won’t do the trick, perhaps biology will. Scientists who work in the field of synthetic (合成的) biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information.
This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive.
In the new experiment, the researchers turned DNA from bacteria(細(xì)菌) into a switch. They “flip (翻轉(zhuǎn))” a small section of DNA. Then, using the same procedure (過程) , the scientists flip the section again—returning it into its normal structure.
Using these DNA switches, “We can write and erase DNA in a living cell,” bioengineer, Jerome Bonnet, explained to Science News.
It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory—less than what a computer uses to remember a single letter.
“This was an important proof that it was doable,” Bonnet told Science News. “Now we want to build a more complex system, something that other people can use.”
小題1:What is the aim of listing the electronic things in the first paragraph?
A.To make the passage more fashionable.
B.To show how electronic things have memory.
C.To discuss things in detail.
D.To make the subject of the text more understandable.
小題2:What is possible future benefit of the cell-based gadget for people?
A.To detect disease at the earliest point.
B.To help improve the memory.
C.To help people build a body.
D.To replace many electronic gadgets.
小題3:What is the object being researched?
A. The cells of bacteria.         
B. The DNA of bacteria.
C. A section of bacteria.         
C. The nucleus of bacteria.
小題4:What do we know about a flipped section of DNA?
A.It has a very small memory.
B.It can function as a computer.
C.It has one letter in it.
D.It takes a day to complete it.

Modern inventions have speeded up people's lives amazingly. Motor cars cover a hundred miles in light more than an hour, aircraft cross the world inside a day, while computers operate at lightning speed. Indeed, this love of speed seems never ending. Every year motor cars are produced which go even faster and each new computer boasts(吹噓) of saving precious seconds in handling tasks.
All this saves time, but at a price.When we lose or gain half a day in speeding across the world in an airplane, our bodies tell us so. We get the uncomfortable feeling known as jet lag;our bodies feel that they have been left behind in another time zone. Again, spending too long at computers results in painful wrists and fingers. Mobile phones also                   , according to some scientists;too much use may put harmful radiation into our brains, a consequence we do not like to think about.
However, what do we do with the time we have saved? Certainly not relax, or so it seems. We are so accustomed to constant activity that we find it difficult to sit and do nothing or even just one thing at a time. Perhaps the days are long gone when we might listen quietly to a story on the radio, letting imagination take us into another world.
There was a time when some people's lives were devoted simply to the cultivation(耕耘) of the land or the care of cattle. No multi tasking there;their lives went on at a much gentler pace, and in a familiar pattern. There is much that we might envy about a way of life like this. Yet before we do so, we must think of the hard tasks our ancestors faced: they farmed with bare hands, often lived close to hunger, and had to make tools from wood and stone. Modern machinery has freed people from that primitive existence.
小題1:What's the passage mainly about?(within 10 words)
                                                                       
小題2:List the difficulties our ancestors met according to the text.(within 15 words)

Thoughts claim our attention continuously, and waste our time and energy on unimportant and useless matters. They actually rule our life. We have become so used to this slavery, that we take it for granted, and have become unconscious of this habit, except on certain occasions.
While breathing, we do not need to pay attention to each inhalation and exhalation. We become conscious of the process of breathing only when we have some difficulty with breathing, such as when our nose is blocked, due to a cold, or when we are in an unventilated(不通風(fēng)的) room.
It is the same with thinking. We become conscious of the constant onslaught of our thoughts, and of our inability to calm them down, only when we need to concentrate, solve a problem or study. We are also aware of them when we have worries or fears.
Look at the following familiar situation. You need to study something for an exam. You sit comfortably on the sofa with the book in your hands and start reading. After a while you feel hungry and go to the kitchen to eat something.
You return to read, and then hear your people talking outside. You listen to them for several moments and then bring your attention back to the book.
After a while you feel restless and switch on the radio to listen to some music. You continue to read for a little while, and then remember something that happened yesterday, and you start thinking about it.
When you look at your watch, you are amazed to find out that one complete hour has passed and you have hardly read anything. And at this time, you feel you’re thinking.
This is what happens when one lacks concentration. Imagine what you could have accomplished if you could control your attention and focus your mind!
小題1:When can you feel you are thinking?
A.While breathing.B.While not reading.
C.When you need to concentrate.D.When you waste your time.
小題2:Why does the author put forward the exam situation?
A.To explain the course of thinking awareness.
B.To show how to get ready for an exam.
C.To present an example of concentration.
D.To emphasize the importance of reading.

A.In a guidebook of natural science.
B.In the front page of a newspaper.
C.In an advertisement part of a magazine.
D.In the section of psychology of a magazine.
小題4:This passage is mainly about _______.
A.the relationship between thoughts and breathing
B.how people’s thought and mind work
C.what happens when one wants to think
D.the ways to increase your thought

Do people ever consider the possibility that, if they’re exposed to increased reports about a social problem, it’s the reporting that has increased rather than the problem? It’s increasingly clear that this is the case with school bullying(欺凌):Only news reports about it have increased, not the behavior itself. In fact, both bullying and fear of it are down among US middle school students
The rate of students who reported fearing an attack or harm at school at all has dropped dramatically, from nearly 12% in 1995 to less than 4% in 2011. For black and Hispanic students, it’s an even more encouraging shift—from more than 20% of both groups of students worried about being attacked at school to less than 5% in 2011.
The decline in actual physical violence in schools is even more dramatic: It was down 74% between 1992 and 2010, according to the latest US Department of Justice data.
What about cyberbullying? Online harassment increased from 6% in 2000 to 9% in 2005 to 11% in 2010 between, and it’s interesting to note that it increased less between 2005 and ’10 than in the first 5 years tracked. Because social media is very much a reflection of school social life for young people, the peer aggression seen in social media is a lot like the peer aggression seen on school bathroom walls. So once it finds its “dead level,” it will probably decline in the same way verbal and written aggression have.
Besides education and crime prevention at the social level, medicine treatment and better access to mental healthcare also contribute to this downward trend in victimization of self and others.
The rise of social media is what people don’t typically think of as a positive force in society. But Finkelhor, director of the Crimes Against Children Research Center at the University of New Hampshire says, “These technologies might have prevented crime and bullying by providing more ways of help, more forms of social supervision, and interesting activities that destroy forms of alienation(異化) that lead to crime”.
小題1:From the first paragraph we learn that __________.
A.school bullying has increased because of increased reports
B.school bullying has decreased because of increased reports
C.the number of reports on school bullying has increased
D.the number of reports on school bullying has decreased
小題2:The underlined word is closest in meaning to "_________".
A.crimeB.a(chǎn)ggressionC.surfingD.communication
小題3:The cyberbullying is still increasing probably because ________.
A.it isn't as easy to control as the other school bullying
B.it hasn't been concerned by the governments
C.it isn't part of school social life
D.it hasn't come to its top level
小題4:Finkelhor believes that social media have a ________ influence on the falling trend of school bullying.
A.positiveB.negativeC.majorD.slight

It should be very clear that we live in a most spectacular(壯觀的)time. It’s a time when information is of primary importance. It’s a time when new information technologies are fundamentally transforming the world in every aspect. Among the changes, which have come upon modern society, the ones in education are probably the most obvious and influential. New information technologies are accelerating changes in education, at the same time presenting revolutionary tools with the potential to make education more efficient and more effective than ever.
The application of new information technologies has remarkably promoted the process of education. Online learning is probably the best case in point. As is often the case with “technology”, online learning may appear to be horrible; it can sound like alphabet soup sometimes. Now let’s see whether you can understand all this. You can participate in CBT at a CLC via the convenience of IDL. What does it all mean? Let me translate: GBT—Computer-Based Training; CLC—Computer Learning Center; IDL—Interactive Distance Learning. Sound complicated? Not really. Online learning is much less complicated than it seems. Students can learn at any time, anywhere, at any speed. They can make their own learning schedules and follow their own paths to suit their lifestyles. In my university, every semester there’re several online courses available, which need no class meetings or paper materials. The only thing I have to do is just to get online regularly as I wish, and download necessary learning materials. Then everything I need to know about the course is only a click away.
But online learning is not perfect; it’s like the microwave oven: it does some things better, but it is not a complete replacement for the traditional model. The traditional classroom model for education and learning is hard to leave behind. Because humans are social creatures, there’re times when we need to see each other face-to-face for interactive learning. A social and personal connection often builds effective teams, solves problems, and inspires confidence. So one possible solution is to combine online learning with the old traditional classroom learning , which not only makes the learning process faster and cheaper, but also highlights the interactions between teachers and students.
The bottom line: the Internet is the most important educational tool in the information age and online learning will become a main part of every individual’s learning experience in the future. That’s exactly how we will move knowledge from the ones who have it to the ones who need it faster and cheaper, and that’s how we’re going to survive in the information age.
小題1:The most suitable title for the passage should be “___________.”
A.Education in the information age
B.Advantages and disadvantages of online learning
C.Online learning vs classroom learning
D.How to survive in the information age
小題2:In Paragraph 3 the microwave oven is mentioned as an example to indicate that_________.
A.online learning needs improving
B.online learning doesn’t suit everyone
C.online learning will exist alongside the traditional model
D.online learning is more advanced than the traditional model
小題3:Which of the following descriptions about online learning is NOT true according to the passage?
A.It is more efficient and effective.
B.It is convenient to both teachers and students.
C.It stresses interactions between teachers and students.
D.It is a cheaper way of learning.
小題4:It can be inferred from the passage that________.
A.not all the people are in favor of online learning
B.it is not easy to combine online learning with classroom learning
C.in the future all the courses will be available online
D.in a sense our survival in the world depends on online learning

Many people in the world live in big cities, which are often dirty and difficult places to live. So, some cities will get bigger. They will also get higher, and lower, because people will begin to live under the ground as well as in tall buildings. Scientists also say that men can begin to live in cities under the sea, when there is not enough space on the land. Of course, these new cities will be very expensive, and difficult to build, but they are not impossible. Already, some countries are building places to live under the ground so their people can go there if there is a new war. There are underground cities in Switzerland(瑞士)and China, built by the government(政府)to help some of the people live during a great war. 
But will people change if they live under the ground for a long time?For example some fish go blind if they live in the dark sea for a long time. People will not go blind, because there will be light underground, but they may change in some way. Scientists say that people who live in cities today are losing their senses of smell, touch and taste. They can’t smell the dirty air, they can’t taste the chemicals(化學(xué)制劑)in their food. These senses are not as strong as before, when people lived in the country and grew their own food. The city has changed that. What will the underground city change in everyone?
小題1:People will live under the ground because _________. 
A.it’s neither hot nor cold there
B.they’ll be afraid of the war
C.there’ll be less space on the ground
D.they’ll make their life comfortable
小題2:Some countries try to build some places under the ground so that people will be able to live there _____.
A.when summer comes
B.when a war breaks out
C.because they think it’ll be safer for them
D.when they’re fed up with the life on the land
小題3:_________, so people who will live there won’t go blind. 
A.There’ll be enough light under the ground
B.It’ll be easy to go upstairs
C.Glasses will be sold under the ground
D.Medicine will be supplied for free
小題4:People will lose some senses under the ground because _______.
A.the world are polluted
B.it’s dark there
C.the air is dirty and there are a lot of chemicals in their food
D.they can’t grow their own food in the sun
