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 plug into electric sockets （插座）, just like many laptops, digital cameras, cell phones and small video game players do. Called “plug-in hybrids （混合动力汽车）,” 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 automobile-filled world, plug-in vehicles could reduce the amount of gasoline we use. That gas is made from crude oil, which has been kept rising in cost. Plus, driving around in these hybrids may even help the environment. Gas-burning 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 company-produced plug-in hybrids could hit the roads by 20l0. But engineers still have a lot of work to do to make the technology practical and inexpensive.
Batteries are the biggest challenge. In the plug-in-hybrid world, Li-ion batteries are getting the most attention. These batteries can store a large amount of energy in a small package, and they last a relatively long time between charges. Li-ion batteries are standard in laptops, cell phones, heart devices and similar portable devices.
But because cars are so big and heavy, it would still require a suitcase-sized Li-ion battery to power about l2km 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 （拖拉） any people, and it would cost $l00,000.”
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 tests and fine-tuning results.”

For years experts have argued that poor households are consuming less nourishing food than the rest of the population. But a survey of some of the lowest earners in Britain shows the nutritional value of what they eat is little different to everyone else. In fact, the same deficiencies in diet were shared by all the population and the findings suggest that poor eating choices are far more widespread than previously suspected - affecting many wealthier families. These included low fruit and vegetable consumption, not eating enough oily fish and eating too much saturated fat and sugar. “This is a large and significant study and it shows we are all eating just as bad a diet as each other,” said Tim Lang, professor of food policy at City University. The poorest families were eating only slightly more sugar and slightly less fruit and vegetables, according to the study of 3,728 respondents in the bottom of the population. Alison Tedstone, head of nutritional science at the Food Standard Agency, said: “ Overall, people on low incomes have less than ideal diets, but their diets are only slightly worse than those of the rest of the population.” The study also showed that low earners are choosing to eat unhealthily. Their food choices were not linked to their income, their access to shops or their cooking skills. The findings appear to contradict assumptions that the poor cannot afford healthier foods or are too far away from shops that sell them. The Low Income Nutrition and Diet Survey showed that like the rest of the population, the poor's daily fruit and vegetable intake on average is below the recommended five portions. Fewer than 10 per cent of respondents hit this target, while around 20 per cent ate less than a portion per day. More than three quarters (76 per cent) of men and 81 per cent of women did less than one 30-minute session of moderate or vigorous exercise per week Some 45 per cent of men and 40 per cent of women were smokers. This compares with 28 per cent of men and 24 per cent of women in the general population. 56. According to the passage, which of the following is true? A. Whether the poor or the rich maybe have a bad diet. B. Even the poor can enjoy enough fruit and fish consumption. C. Only the poor have a bad diet. D. The study was conveyed in both the rich and the poor. 57. What kind of persons maybe eat most sugar? A. The rich. B. Men. C. The poorest. D. Women 58. From the passage, we can learn __________. A. the poor choose unhealthy food because of low income B. having no access to shops also leads to the poor’s bad diet C. the poor’s daily fruit intake is as much as general people D. the number of smokers in the poor is bigger than that in general people 59. What’s the best title of the passage?[ A. The poor’s healthy problem. B. Keep off junk food. C. How to have a good diet. D. A diet survey. 查看答案和解析>> 同步练习册答案 湖北省互联网违法和不良信息举报平台 | 网上有害信息举报专区 | 电信诈骗举报专区 | 涉历史虚无主义有害信息举报专区 | 涉企侵权举报专区 违法和不良信息举报电话：027-86699610 举报邮箱：58377363@163.com版权声明：本站所有文章，图片来源于网络，著作权及版权归原作者所有，转载无意侵犯版权，如有侵权，请作者速来函告知，我们将尽快处理，联系qq：3310059649。 ICP备案序号: 沪ICP备07509807号-10 鄂公网安备42018502000812号 |
