A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband (腕套). The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time between
the sound the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.

China is a land of bicycles.At least it was back in 1992 when I traveled the country.Back then everyone seemed to be riding a bicycle.Millions of them, all black.Cars were rare.Yet since my arrival in Beijing last year.I've found the opposite is true.There are millions of cars.However, people still use their bicycles to get around.For many, it's the easiest and cheapest way to travel today.Bicycles also come in different colors—silver, green, red, blue, yellow, whatever you want.

In ninth grade, I thought Jennifer Fever, the dark-haired girl who sat behind me in classroom, was an alien(外星人). Our class organized an activity to raise money for the library, and in one month, Jennifer read 34 books. I couldn’t believe it. Surely, she was from some faraway planet where creature lived and they didn’t own television sets. How could a human being, a 13-year-old girl, read 34 books in one month?
I had read three books. And by “read”, I mean skimmed. I mean opened and placed them on my lap while watching cartoons.
Who had time to read? In addition to my favorite cartoons, I had a basketball that required playing, a baseball that required throwing, and a volleyball that required volleying. And it wasn’t as if my bike could ride itself.
Besides, reading was boring. And if I wanted to be bored, it would be much easier just to pay attention during Mr. Kearly’s social studies class.
After senior high school, my education had become very narrow: computer engineering, mathematics, physics, and not much else.
Years later, I realized something: I had not memory of ever reading a book for pleasure. But there was a world of knowledge outside science and engineering, and I was tired of being ignorant(无知的)of it, so I decided I would become a reader. I dived into book after book. In short, the bookworm within me had awakened.
Today, I carry a book(if not two or three) with me wherever I go. An hour-long waiting for the bus is not trouble; rather, it’s a chance to enjoy a few chapters of Malcolm Gladwell’s latest works. Sometimes, I wish my waiting was longer.
【小题1】 From the first paragraph, we learn that Jennifer Fever .
| A．was an alien | B．couldn’t believe me |
| C．organized an activity | D．was my classmate |

| D．Riding her bike. |
| A．My education had become very narrow after high school. |
| B．A 13-year-old girl could also read 34 books in one year. |
| C．I skimmed my three books while reading in the library. |
| D．I was still tired of reading during my study in the university. |
| A．enjoyed some faraway planet very much |

Now Hear This
What do former American president Bill Clinton and rock musician Pete Townshend have in common? Both men have hearing damage from exposure to loud music, and both now wear hearing aids as a consequence. As a teenager, Clinton played saxophone in a band. Townshend, who has the more severe hearing loss, was a guitarist for a band called the Who. He is one of the first rock musicians to call the public's attention to the problem of hearing loss from exposure to loud music.
Temporary hearing loss can happen after only 15 minutes of listening to loud music. One early warning sign is when your ears begin to feel warm while you listen to music at a rock concert or through headphones. One later is that an unusual sound or a ringing is sometimes produced in your head after the concert.
"What happens is that the hair cells in the inner ear are damaged, but they're not dead," says a physician and ear specialist Dr. Sam Levine. According to Dr. Levine, if you avoid further exposure to loud noise, it's possible to recondition the cells somewhat. However, he adds, "Eventually, over a long period of time, hair cells are permanently damaged." And this is no small problem.
What sound level is dangerous? According to Dr. Levine, regular exposure to noise above 85 decibels (分贝) is considered dangerous. The chart below offers a comparison of decibel levels to certain sounds. Here's another measurement you can use. If you're at a rock concert and the music is so loud that you have to shout to make yourself heard, you' re at risk for hearing loss. That's when wearing protective devices such as earplugs becomes critical.
The facts are pretty frightening. But are rock bands turning down the volume? Most aren't. "Rock music is supposed to be loud," says drummer Andrew Sather. "I wouldn't have it any other way. And neither would the real fans of rock. "
Continued exposure to loud music and the failure to wear earplugs can lead to deafness, according to Dr. Levine. He states, "There's no cure for hearing loss. Your ears are trying to tell you something. That ringing is the scream of your hair cells dying. Each time that happens, more and more damage is done. "
| Levels of Common Noises Normal conversation 50 — 65 dB Food blender 88 dB Jet plane flying above a person standing outside 103 dB Rock band during a concert 110 — 140 dB |
| A．loud music is a major cause of hearing loss |
| B．famous people tend to have hearing problems |
| C．teenagers should stay away from school bands |
| D．the problem of hearing damage is widely known |
| A．not to be seen | B．to fill with sound |
| C．to become larger in size | D．to make good again |
| A．a list of harmful sounds |
| B．the effect of rock concerts |
| C．the noise levels of familiar sounds |
| D．relationship between daily activities and hearing loss |
| A．When your ears feel warm, your hair cells are dead. |
| B．Drummer Andrew Sather gives good advice. |
| C．Many are taking the risk of losing hearing. |
| D．Doctors know how to cure hearing loss. |

It’s puzzling, isn’t it? No matter where you try to tickle（使人发痒）yourself, even on the soles（脚底） of your feet or under your arms, you just can’t.
To understand why, you need to know more about how your brain works. One of its main tasks is to try to make good guesses about what’s going to happen next. While you’re busy getting on with your life, walking downstairs or eating your breakfast, parts of your brain are always trying to predict the future.
Remember when you first learned how to ride a bicycle? At first, it took a lot of concentration to keep the handlebars steady and push the pedals（踏板）. But after a while, cycling became easy. Now you’re not aware of the movements you make to keep the bike going. From experience, your brain knows exactly what to expect so your body rides the bike automatically. Your brain is predicting all the movements you need to make.
You only have to think consciously about cycling if something changes---like if there’s a strong wind or you get a flat tyre. When something unexpected happens like this, your brain is forced to change its predictions about what will happen next. If it does its job well, you’ll adjust to the strong wind, leaning your body so you don’t fall.
Why is it so important for our brains to predict what will happen next? It helps us make fewer mistakes and can even save our lives. For example, when a chief fireman sees a fire, he immediately makes decisions about how best to position his men. His past experiences help him foresee what might happen and choose the best plan for fighting the fire. His brain can instantly predict how different plans would work out, and he can rule out any bad or dangerous plans without putting his men at risk in real life.
So how does all this answer your question about tickling? Because your brain is always predicting your own actions, and how your body will feel as a result, you cannot tickle yourself. Other people can tickle you because they can surprise you. You can’t predict what their tickling actions will be.
【小题1】What is the best title for this passage?
| A．How Does the Brain work? |
| B．Why Can’t I Tickle Myself? |
| C．The importance of Prediction |
| D．The Importance of Our Brains |
| A．walk down the stairs |
| B．eat our breakfast |
| C．suddenly lose our balance and fall |
| D．ride a bike |
| A．decide that something is not suitable | B．think about |
| C．act according to the rules | D．expect |
| A．a scientific report for experts |
| B．a textbook for medical students |
| C．a book for children |
| D．a research paper for doctors |

I went to a nearby car factory today with my uncle, who works there. One thing I noticed was that most of the work was done by robots. Welding (焊接), painting, testing and many other jobs are performed by robots. The whole dashboard (仪表板) is put into a car by a robot. It would have taken two men to do so in the past, and it would have hurt their backs quite a bit.
It got me thinking: Is it a good thing that robots are replacing factory workers? On the one hand, robots generally do a more accurate job than people. They are not likely to make many mistakes. If something goes wrong with one car, an alarm goes off. They do exactly the same thing every time, but a human worker is unable to do so. On the other hand, robots reduce costs for companies. Companies don’t have to pay robots wages or injury compensation (补偿) if they’re broken. If something in a robot does go wrong, it won’t have to take time off work for a year, or even forever, as could happen to a real person if he breaks his back or burns himself while welding.
The obvious downside is that robots increase unemployment rate, which in turn increases taxes. We don’t want to pay for those who are out of work just because a company has replaced them with robots.
【小题1】We can learn from the first paragraph that _______.
| A．all the workers have been replaced by robots |
| B．robots do most of the work in the car factory |
| C．there are no workers with back strain now |
| D．the author’s uncle designs robots in the factory |
| A．the author’s experience in a car factory |
| B．the advantages of robots over human workers |
| C．the advantages of human workers over robots |
| D．the management of factory workers |
| A．weakness | B．favor |
| C．assistance | D．Advantage |
| A．companies refuse to pay for workers. |
| B．robots have completely replaced workers. |
| C．robots can help solve the problem of unemployment. |
| D．people have to pay more taxes for unemployment. |

There are many ways to find a job. It can be as easy as walking into a neighborhood store to look at its announcement board. Local stores often have areas where people can put small signs telling what kind of service they need or can provide. Such services include caring for children or cleaning houses.
Or, job searchers can look in the newspaper. Local newspapers have employment announcements placed by companies seeking workers.
Another popular tool for finding jobs is the Internet. For example, people in four hundred and fifty cities around the world can use the Craigslist Web site to buy objects, meet people or find a job. Craigslist says that it receives two million new job listings each month.
Another useful way to find a job is through a college or university. For example, students at the University of Texas in Austin can go to the Career Exploration Center to get help in finding a job. Of course, looking for a job requires knowing what kind of work you want to do. For example, there is a book called “What Color is Your Parachute (降落伞)?” by Richard Bolles. This book has been helping people choose a career (职业) since it was first published in nineteen seventy.

For most city people, the elevator is an unremarkable machine that inspires none of the enthusiasm or interest that Americans afford trains, jets，and even bicycles. Dr. Christopher Wilk is a member of a small group of elevator experts who consider this a misunderstanding. Without the elevator, they point out, there could be no downtown skyscrapers or tall buildings, and city life as we know it would be impossible. In that sense, they argue，the elevator’s role in American history has been no less significant than that of cars. In fact, according to Wilk? the car and the elevator have been locked in a “secret war” for over a century, with cars making it possible for people to spread horizontally (水平地)，and elevators pushing them toward life in close groups of towering vertical (垂直的)columns.
If we tend to ignore the significance of elevators, it might be because riding in them tends to be such a brief, boring, and even awkward experience^one that can involve unexpectedly meeting people with whom we have nothing in common, and an unpleasant awareness of the fact that we’re hanging from a cable in a long passage.
In a new book, Lifted, German journalist and cultural studies professor Andreas Bernard directed all his attention to this experience, studying the origins of elevator and its relationship to humankind and finding that riding in an elevator has never been a totally comfortable experience. “After 150 years, we are still not used to it”， Bernard said. “We still have not exactly learned to cope with the mixture of closeness and displeasure.” That mixture, according to Bernard, sets the elevator ride apart from just about every other situation we find ourselves in as we go about our lives.
Today，as the world’s urban population explodes，and cities become more crowded, taller, and more crowded, America’s total number of elevators—900,000 at last count, according to Elevator World magazine’s “2012 Vertical Transportation Industry”一are a force that’s becoming more important than ever. And for the people who really, really love them, it seems like high time that we looked seriously at just what kind of force they are.
【小题1】What does the underlined word “this” in Paragraph 1 refer to?
| A．The general view of elevators. |
| B．The particular interests of experts. |
| C．The desire for a remarkable machine. |
| D．The enthusiasm for transport vehicles. |
| A．to contrast their functions with elevators, |
| B．to emphasize the importance of elevators |
| C．to reveal their secret war against elevators |
| D．to explain people’s preference for elevators |
| A．Vertical direction. |
| B．Lack of excitement. |
| C．Little physical space. |
| D．Uncomfortable conditions. |
| A．the exact number of elevator lovers |
| B．the serious future situation of elevators |
| C．the role of elevators in city development |
| D．the relationship between cars and elevators |
