And even if a person is poor he doesn't feel really poor when he has a car. Henry Ford was the man who first started making cars in large numbers. He probably doesn't know how much the car was going to affect American culture. The car made the United States a nation on wheels. And it helped to make the United States what it is today. There are many reasons that the car became so popular in the United States. First of all, the country was a large one and Americans like to move around in it. The car provides the most comfortable and cheapest from of transportation. With a car people can go to any place without spending a lot of money. The second reason that cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long distance trains have never been as common in the United States as they are in the other parts of the world. Nowadays there is good system of air service provided by planes. But it is too expensive to be used frequently. The third reason is the most important one. The American spirit of independence is what really made cars popular. Americans don't like to wait for a bus, or a train or even a plane. They don't like to have to follow an exact schedule. A car gives them the freedom to plan their own time. And this is the freedom that Americans want most to have. The gas shortage has caused a big problem for Americans. But the answer will not be a bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much gas. Question: "a nation on wheels" means _ - the nation is producing the best cars in the world - everyone in this country owns a car - cars play a very important role in people's life - there are more cars than trains in the country
cars play a very important role in people's life

The child looked at him with a kind of half attention, his eyes forward but not yet engaged. They were a paler blue than his father's as if they might have faded like the shirt; one of them listed, almost imperceptibly , toward the outer rim. "He was in a path," Sheppard said, "and he had his hand in a garbage can. He was trying to get something to eat out of it." He paused to let this soak in. "He was hungry," he finished, and tried to pierce the child's conscience with his gaze. The boy picked up the piece of chocolate cake and began to bite it from one corner. "Norton," Sheppard said, "do you have any idea what it means to share?" A flicker of attention. "Some of it is yours," Norton said. "Some of it is his," Sheppard said heavily. It was hopeless. Almost any fault would have been preferable to selfishness--a violent temper, even a tendency to lie. The child turned the bottle of tomato sauce upside-down and began thumping sauce onto the cake. Sheppard's look of pain increased. "You are ten and Rufus Johnson is fourteen," he said. "Yet, I'm sure your shirts would fit Rufus." Rufus Johnson was a boy whom he had been trying to help at the reformatory for the past year. He had been released two months ago. "When he was in the reformatory, he looked pretty good, but when I saw him yesterday, he was skin and bones. He hasn't been eating cake with peanut butter on it for breakfast." The child paused. "It's not fresh," he said. "That's why I have to put stuff on it." Sheppard turned his face to the window at the end of the bar. The side lawn, green and even, sloped fifty feet or so down to a small suburban wood. When his wife was living, they had often eaten outside, even breakfast on the grass. He had never noticed then that the child was selfish. ks5u "Listen to me," he said, turning back to him, "look at me and listen." The boy looked at him. At least his eyes were forward. "I gave Rufus a key to the house when he left... Question: What is the point of this conversation between father and son? - The father intends to make his son accept the idea that Rufus may stay in their house. - The father wants his son to learn from Rufus. - The father wants to look after Rufus because he is skin and bones now. - The father intends to give his son a lesson because he seems to be spoilt.

Here's good news: you can combine all of these career goals by designing, building and operating a solar-powered house. That is what students from 20 universities did as they competed in the U.S. Department of Energy 2009 Solar Decathlon . Like a game show where teams compete against each other, the Solar Decathlon's student teams competed against each other in ten separate events to see who could build the best solar-powered house. The team from Germany took the top honor. The contest is held on the National Mall in Washington D.C., and is open to the public. In order to win, the Decathlon's teams have to successfully host a dinner party, do the laundry, run the dishwasher, and maintain a comfortable temperature in their solar-powered houses. They also have to make their houses look attractive. Team Germany's winning "Cube House" produced a surplus of power, even during three days of rain. This is the fourth time the Solar Decathlon has been held. The houses keep getting better and better. "The Department of Energy does research on solar and building technologies. In the 1990s, we were seeking expertise to help design houses that would integrate solar systems in a reliable way. I came up with the idea of having a competition to challenge students at architecture and engineering schools to design solar-powered houses from the ground up. I thought that having a competition would motivate these students to be creative. The new generation of our country should be innovative . They may come up with solutions that would help our country," said Richard J. King, the Decathlon's Director. Question: What do we know about the Solar Decathlon from the text? - The participated teams are separated from the outside world during the competition. - The house designed by the German team will be adopted by the Department of Energy. - The competition had been held three times before 2009. - It includes students from twenty countries around the world.
The competition had been held three times before 2009.
