Car companies are developing vehicles that will plug into electric sockets，just like many laptops，digital cameras，cell phones and Mp4 do．Called“plug-in vehicles”，these cars will get most of their power from electricity. Their drivers won't have to stop at gas stations as often as usual．
The technology is more than just cool. In our car-filled world，plug-in vehicles could reduce the amount of gas we use，which keeps rising in cost now and then. Besides，driving around in these vehicles may even help the environment．Gas-burning cars produce a lot of greenhouse gas，which causes globe warming.
The first company-produced plug-in vehicles could hit the roads by 2010. But engineers still have a lot of work to do to make the technology practical and inexpensive．
Ba
tteries(電池) are the biggest challenge. In the plug-in-vehicle world，Li-ion(鋰離子)batteries are getting the most attention．These batteries can store a large amount of energy in a small package，and they last a longer time between charges．Li-ion batteries can fit laptops，cell pho
nes，heart instruments and other similar pocket ones.
But because cars are so big and heavy, it would still require a suitcase-sized Li-ion batteries to power about 12km of driving．What's more，the batteries are much expensive．
“A car filled with batteries could go a long distance，”says Ted Bohn, an electrical engineer in Chicago．“But it couldn't pull any people．a(chǎn)nd it would cost $100,000．”
So researchers need to work out how to make batteries smaller and cheaper，among other questions.
“The answers don't exist yet，”Bohn says，“As a kid，I thought someone someplace knows the answer to everything．All of these questions haven't been decided．That's what engineering is about-making a guess，running tests and getting fine results．”

It’s Friday morning in the year 2030, and you’re running late. You got carried away watching the music video that was playing in the corner of your bathroom mirror while you were brushing your teeth. How will you get to your office at Mega Giga Industries on time?
A quick check of your Internet–connected refrigerator tells you your train is a bit behind schedule, too. So you decide to drive your environmentally–friendly fuel cell car instead—or rather, let your car drive you. It’s programmed to know the way and it will get you there without speeding, getting lost, or crashing.
Settling into your office chair, which changes color to match what you’re wearing, you pick up yesterday morning’s newspaper. Printed on reusable electronic paper, it immediately rewrites itself with today’s headlines. Now it’s time for your big meeting. Uh-oh! You’ve left your handwritten notes at home. No problem. The digital ink pen you used has stored an electronic copy of what you wrote.
Your wristwatch videophone (可視電話) suddenly rings. Your best friend’s face pops up on the screen (屏幕) asking what you’re doing this weekend. Will you play virtual soccer with the U.S. Olympic team? No, no. Your friend says, so you have to take the new elevator (made of microscopic fibers many times stronger than steel) 60000 miles into space.
Could this scene really take place in just twenty years? The researchers who are now developing all this stuff think so. These gadgets (小器械) may be as common in 20 years as cell phones and DVD players are today.

The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image （形象）of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. “We were surprised by just how positive today’s young people seem to be about their families,” said one member of the research team. “They’re expected to be rebellious（叛逆的）and selfish .but actually they have other things on their minds: they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation（商議）and discussion between parents and children, and children expect to take part in the family decision-making process. They don’t want to rock the boat.”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me," says 17-year-old Daniel Lazall. “I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.” Susan Crome, who is now 21, agrees. “Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments, “Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”
41. What is the popular image of teenagers today?
A. They worry about school. B. They dislike living with their parents.
C, They have to be locked in to avoid troubles. D. They quarrel a lot with other family members.
42. The study shows that teenagers don’t want to__________ .
A. share family responsibility B. cause trouble in their families
C. go boating with their family D. make family decisions
43. Compared with parents of 30 years ago, today’s parents__________ .
A. go to clubs more often with their children B. are much stricter with their children
C. care less about their children’s life D. give their children more freedom
44. According to the author, teenage rebellion__________ .
A. may be a false belief B. is common nowadays
C. existed only in the 1960s D. resulted from changes in families
45. What is the passage mainly about?
A. Negotiation in family. B. Education in family.
C. Harmony in family. D.Teenage trouble in family.
