When a handheld video game runs out of power,all you have to do is plug it in and charge it up.Within a few years,some of you might do the same thing with mom's car.Automobile companies are developing vehicles that will plugin to electric sockets ,just like many laptops,digital cameras,cellphones and small video game players do.Called "plugin hybrids ",these cars will get most of their power from electricity.Their drivers will rarely have to stop at gas stations. The technology is more than just cool.In our automobilefilled world,plugin vehicles could reduce the amount of gasoline we use.That gas is made from crude oil ,which keeps rising in cost.Plus,driving around in these hybrids may even help the environment.Gasburning cars produce a lot of carbon dioxide,a type of greenhouse gas.These gases stay in the atmosphere,where they trap heat and cause global warming. The first companyproduced plugin hybrids could hit the roads by 2010.But engineers still have a lot of work to do to make the technology practical and inexpensive. Batteries are the biggest challenge.In the pluginhybrid world,lithiumion (Liion) batteries are getting the most attention.These batteries can store a large amount of energy in a small package,and they last a ly long time between charges.Liion batteries are standard in laptops,cellphones,heart devices and other similar portable devices. But because cars are so big and heavy,it would still require a suitcasesized Liion battery to power about 12km of driving.What's more,the batteries are extremely expensive. "A car filled with batteries could go a long distance," says Ted Bohn,an electrical engineer in Chicago."But it couldn't haul any people,and it would cost $100,000." So researchers need to figure 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... The passage mainly talks about _ of a new car. A) the batteries B) the speed C) the developing D) the appearance

Imagine you are standing on the 70thfloor of the Empire State Building, staring at the cityscape. Suddenly a man pushes past you, opens the window and announces his intention to jump. You yell out, "Stop! Don't do it!" the six-foot-five figure turns to you and menacingly says, "Try to stop me and I'll take you with me!" "Umm... No problem, sir. have a good trip. any last words?" "Let me tell you my troubles," he says, "my wife left me, my kids won't talk to me, I lost my job and my pet turtle died, so why should I go on living?" Suddenly you have a flash of inspiration. "Sir, close your eyes for a minute and imagine that you are blind. No colors, no sights of children playing, no fields of flowers, no sunset. Now imagine that suddenly there's a miracle. You open your eyes and your vision is restored! Are you going to jump? Or will you stick around for a week to enjoy the sights?" "I'll stay for a week." "But what happened to all the troubles?" "I guess they're not so bad. I can see!" " _ " If you really appreciate your eyesight, the other pains are insignificant. But if you take it all for granted, then nothing in life will ever truly give you joy. Actually, there are misconceptions on the road to happiness. misconception1: "Once I know the tools for being happy, then it will work like magic." Don't expect the results to come automatically. It is possible to understand how to achieve happiness, yet not put it into practice. In fact, many people actually prefer to be comfortable and unhappy, rather than bear the discomfort of changing their habits. Just as learning any new skill requires effort, you have to be willing to invest serious effort to achieve real happiness. Misconception 2: "if I become content and satisfied with what I have, I'll lose my motivation to achieve more." Now ask someone who is depressed, "Let's go fishing!" "I'm tired. Maybe tomorrow. And anyway, I might rain..." in reality, happy people are energetic and ambitious. There's never enough time to do everything they want to... The best subtitle of Misconception 3 is _ . A) If unhappy occurs at home, I needn't pretend to be happy B) If I can't make others unhappy, I won't be happy. C) If someone is happy, then others around them are happy. D) If I want to be depressed, that's my own prerogative.

Ques:Dear Students, I am delighted to be your guest. I would like to tell you about myself. I have been a news reporter for the past fifteen years. I chose this job so I could travel the world, but the job has taught me many unforgettable lessons. The work is sometimes difficult. I have seen _ , wars, earthquakes, poverty and death. But I have also seen courage, hope and happiness. In India, I visited a city where there were many homeless children. Some were as young as four years old. They lived in the streets and survived by begging or stealing. But then a wonderful lady called Rosa opened a home for them. Within one year, she was looking after two hundred children. She clothed them, fed them, and taught them. She gave them hope. Another time, I was in Turkey after a terrible earthquake, in one place. I found an old lady whose house was in ruins, her son was missing and rescue workers said there was no chance that he was still alive. But the old lady did not give up hope. For four days, she moved heavy stones one at a time by herself. She did not stop until she found her son. He was alive. Here in China, I met a young boy with a serious condition. He had undergone twenty operations and spent nearly his whole life in hospital. I thought he would be sad, but when I met him, his smile was so warm and welcoming. In life, we need role models that we can admire and learn from. When my life is difficult, I try to remember the courage and goodness of these three people.
