Like many other small boys, I was fascinated by cars, not least because my oldest brother was a bit of a car guy and subscribed to cool magazines like Car and Driver and Motor Trend. Every so often, one of those magazines would run an article on the “Car of the Future”. They featured unconventional styling and things like small nuclear reactors as power sources. Yet, frankly, my car doesn’t do anything that my brother’s Studebaker didn’t do. It goes, it stops, it burns gasoline, it plays music. I still have to steer it, and it still runs into things if I don’t steer it carefully.
But guess what? All of these things are subject to change in the not-so-distant future. It will still go and stop, but it may not burn gasoline, I may not have to steer it, and it may be a lot better at not running into things.
Airbags aren't the be-all and end-all in safety. In fact, considering the recent news about people occasionally being killed by their airbags in low-speed collisions (碰撞),they obviously still need some development. But they aren't going away, and in fact, you can expect to see cars appearing with additional, side-impact airbags, something some European car manufacturers already offer.
Better than systems to minimize (使减少到最低限度) injury in the event of an accident, however, are systems that minimize the likelihood of an accident happening in the first place. Future cars may be able to eliminate many of the major causes of accidents, including drunk-driving, tailgating (与前车距离过近) and sleepiness. Cars could be equipped with sensors that can detect alcohol in a driver's system and prevent the car from being started, for example. Many accidents are caused by people following the car in front too closely. As early as next year, you'll be able to buy cars with radar-equipped control systems. If the radar determines you're closing too quickly with the car in front, it will ease up on the throttle (油门). For city streets, expect other radar devices that will give advance warning that the car in front of you has slowed abruptly (突然地) and you should step on the brakes-or that may even brake for you.
Will cars eventually be able to drive themselves? There's no reason to think it won't be technically possible, and Mercedes is working on a system that can brake, accelerate and steer a vehicle down a highway on its own. Nobody really expects people to give up all control to their cars, but such systems could be used as failsafe systems to keep cars on the road and bring them safely to a stop even if the driver suddenly became disabled.

Like many of my generation, I have a weakness for hero worship. At some point, however, we all begin to question our heroes and our need for them. This leads us to ask: What is a hero?
Despite immense differences in cultures, heroes around the world generally share a number of characteristics that instruct and inspire people.
A hero does something worth talking about. A hero has a story of adventure to tell and community who will listen. But a hero goes beyond mere fame.
Heroes serve powers or principles larger than themselves. Like high-voltage transformers, heroes take the energy of higher powers and step it down so that it can be used by ordinary people.
The hero lives a life worthy of imitation. Those who imitate a genuine hero experience life with new depth, enthusiasm, and meaning. A sure test for would-be heroes is what or whom do they serve? What are they willing to live and die for? If the answer or evidence suggests they serve only their own fame, they may be famous persons but not heroes. Madonna and Michael Jackson are famous, but who would claim that their fans find life more abundant?
Heroes are catalysts (催化剂) for change. They have a vision from the mountaintop. They have the skill and the charm to move the masses. They create new possibilities. Without Gandhi, India might still be part of the British Empire. Without Rosa Parks and Martin Luther King, Jr., we might still have segregated (隔离的) buses, restaurants, and parks. It may be possible for large-scale change to occur without leaders with magnetic personalities, but the pace of change would be slow, the vision uncertain, and the committee meetings endless.

Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.
This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured(had)three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.
Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.
"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."
Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped (fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.
The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.
"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

B.You can improve your bicycle for science research. |
C.Many inventions are connected with the bicycle. |

C.Renato’s improvement of the bicycle has solved the country’s great problem. |
D.Renato’s special bicycle will soon be put into use in remote areas.’ |
3.The underlined word “address” in the third paragraph probably has the same meaning as _______.
A.make address written |
B.give up |
C.work at |
D.speak at |
