An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they're speeding. When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.
The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver's PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car's speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds.
Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they're now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said. “The system even has the capability to record speeding violations, so parents can monitor their teenage drivers.”The product will soon go on sale in Sydney.

Driving in Canada is similar to driving in many parts of the United States. Distances and speeds, however, are posted in kilometers per hour and some signs, particularly in Quebec, may only be in French.
Unless otherwise posted, the maximum （最大限度的）speed limit in Canada is 50km/hr in cities and 80km/hr on highways. On rural highways, the posted speed limit may be 100km/hr. It is not allowed to take automobile radar detectors（汽车雷达检测器）into Quebec, Ontario, Manitoba, and the Yukon. Seat belt use is required by law for all passengers, and child car seats must be used by children under 40 pounds. Some provinces require drivers to keep their vehicles' headlights on during the day and some have banned （禁止）driving while using a hand-held cellphone. Motorcycles cannot share a lane （车道），and safety helmets for motorcycle riders and passengers are necessary. Running a red light is a serious crime throughout Canada and drivers are advised to stop before starting when a light turns green.
Winter travel can be dangerous due to heavy snowfalls and icy conditions. Some roads and bridges are often closed in winter. Snow tires are required in some provinces. Travelers should also be careful about animals while driving at night in rural areas.
Highway 401，from Detroit to Montreal, is one of the busiest highways in North America. It has been the scene of many deadly traffic accidents due to sudden and severe weather changes, high rates of speed, and heavy truck traffic. Thus drivers should be alert while travelling here.

It is quite reasonable to blame traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible. Everybody knows that the nicest men would become fierce tigers behind the wheel.
Road politeness is not only good manners, but good sense. It takes the most cool-headed drivers' great patience to give up the desire to beat back when forced to face rude driving. On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting. A friendly nod or a wave of thanks in answer to an act of politeness helps to create an atmosphere of good will and becomes so necessary in modern traffic conditions. But such behaviors of politeness are by no means enough. Many drivers nowadays don't even seem able to recognize politeness when they see it.
However, misplaced politeness can also be dangerous. Typical examples are the driver who waves a child crossing the street at a wrong place onto the path of oncoming cars that may not be able to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to.
An experienced driver, whose manners are faultless, told me it would help if drivers learnt to correctly join in traffic stream without causing total blockages that give rise to unpleasant feelings. Unfortunately, modern drivers can't even learn to drive, let alone master the roadmanship. Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take from all road users. It is high time for all of us to take this message to heart. The passage mainly talks about __________.
| A．traffic jams |
| B．road politeness |
| C．good manners |
| D．modern drivers |
Troubles on the road are often caused by __________.
| A．the behavior of the drivers |
| B．traffic jams |
| C．great speed |
| D．terrible road conditions |
According to the writer, a good driver should __________.
| A．be able to recognize politeness when he sees it |
| B．beat back when forced to face rude driving |
| C．encourage old ladies to cross the roads whenever they want to |
| D．join in traffic stream quickly however other people feel |
The following statements are right EXCEPT that __________.
| A．some modern drivers are not good at driving |
| B．road politeness is good sense as well as good manners |
| C．drivers are expected to master the roadmanship |
| D．traffic jams are caused by tigers behind the wheel |
It is not always right for drivers to __________.
| A．master roadmanship |
| B．recognize politeness when they see it |
| C．give a friendly nod or wave in answer to an act of politeness |
| D．wave a child crossing the street onto the path of oncoming cars |
Olaf Stapledon wrote a book called First and Last Men, in which he looked millions of years ahead. He told of different men and of strange civilizations（文明），broken up by long "dark ages" in between. In his view, what is called the present time is no more than a moment in human history and we are just the First Men. In 2，000 million years from now there will be the Eighteenth or Last Men.
However, most of our ideas about the future are really very short-sighted. Perhaps we can see some possibilities for the next fifty years. But the next hundred? The next thousand? The next million? That's much more difficult.
When men and women lived by hunting 50，000 years ago, how could they even begin to picture modern life? Yet to men of 50，000years from now, we may seem as primitive（原始的）in our ideas as the Stone-Age hunters do to us. Perhaps they will spend their days gollocking to make new spundels, or struggling with their ballalators through the cribe. These words, which I have just made up, have to stand for things and ideas that we simply can't think of.
So why bother even to try imagining life far in the future? Here are two reasons. First, unless we remember how short our own lives are compared with the whole human history, we are likely to think our own interests are much more important than they really are. If we make the earth a poor place to live on because we are careless or greedy （贪婪）or quarrelsome, our grandchildren will not bother to think of excuses for us.
Second, by trying to escape from present interests and imagine life far in the future, we may arrive at quite fresh ideas that we can use ourselves. For example, if we imagine that in the future men may give up farming, we can think of trying it now. So set your imagination free when you think about the future. A particular mention made of Stapledon's book in the opening paragraph __________.
| A．serves as a description of human history |
| B．serves as an introduction to the discussion |
| C．shows a disagreement of views |

Welcome to your future life ！
You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035，medical technology is better than ever. Many people your age could live to be 150，so at 40，you're not old at all. And your parents just had an anti-aging（抗衰老的） treatment. Now, all three of you look the same age!
You say to your shirt，"Turn red. "It changes from blue to red. In 2035，" smart clothes" contain particles（粒子）much smaller than the cells in your body. The particles can be programmed to change your clothes' color or pattern.

A black hole is created when a large star burns out. Like our sun, stars are unbelievably hot furnaces（熔炉）that burn their own matter as fuel. When most of the fuel is used up, the star begins to die.
The death of a star is not a quiet event. First there is a huge explosion. As its outer layer is blasted off into space, the dying star shines as brightly as a billion suns.
After the explosion gravity pulls in what's left of the star. As the outside of the star sinks toward the center, the star gets smaller and smaller. The material the star is made of becomes tightly packed together. A star is so dense that a teaspoon of matter from it weighs billion of pounds.
The more the star shrinks, the stronger the gravity inside it becomes. Soon the star is very tiny, and the gravity pulling it in is un-believably strong. In fact, the gravity is so strong that it even pulls light into the star! Since all the light is pulled in, none can go out. The star becomes black when there is no light. Then a black hole is born!
That's what we know about black holes. What we don't know is this ： What happens inside a black hole after the star has been squeezed into a tiny ball? Does it keep getting smaller and smaller forever? Such a possibility is hard to imagine.
But if the black hole doesn't keep shrinking, what happens to it? Some scientists think black holes are like doorways to another world. They say that as the star disappears from our universe, it goes into another universe. In other words a black hole in our universe could turn into a " white hole" in a different universe. As the black hole swallows light, the white hole shines brightly-somewhere else. But where? A different place, perhaps, or a different time-many years in the past or future.
Could you travel through a black hole? Right now, no. Nothing we know of could go into a black hole without being crushed. So far the time being, black holes must remain a mystery.
Black holes are a mystery-but that hasn't stopped scientists from dreaming about them. One scientist suggested that in the future we might make use of the power of black holes. They would supply all of Earth's energy needs, with plenty to spare. Another scientist wondered if a black hole could some day be used to swallow earthly waste-a sort of huge waste disposal（处理）in the sky! When the star begins to die __________.
| A．there is no fuel left in it |
| B．its outer layer goes into space first |
| C．a huge explosion will happen |
| D．it doesn't give off light any longer |
Which of the following doesn't help produce a black hole?
