Electricity, like clean water, is a resource that’s often taken for granted. But last summer, when blackouts struck much of the northeastern US, Ontario and Rome, consumers on two continents were given a painful reminder of just how easily broken electricity supplies can be. The massive disorder stranded (使陷入困境)commuters, stopped freezers, shut down businesses and refocused attention on where most of the planet’s power comes from：oil-and-gas-fired generators and nuclear plants, These sources not only pollute the environment but also make many consumers feel unacceptable health risks.
Companies are trying to offer an alternative, clean energy from renewable resources that’s plentiful and portable. Lifton’s Medis Technologies, as well as companies like Hydrogenics and Nanosys, is tapping into fuel cells and dolor panels to give people power whenever and wherever they want it, free from dependence on local grids(电网).
The search for alternative energy is nothing new, but the current trend of innovators is focusing on the goal of making clean and sustainable power a mainstream commodity. For example, the fuel cell, which produces electricity from the chemical reaction between oxygen and hydrogen, has been around for about 150 years, though its commercial development did not begin until the 1960s and then only as part of NASA spacecraft. Today this technology is coming down to Earth in places like Tokyo; in nine European cities, from Stockholm to Porto, each operating three hydrogen-fuel-cell buses; and in Iceland, which is trying to create the first fuel free hydrogen economy by 2030.
When hydrogen and oxygen molecules(分子)combine, the reaction produces heat and water. Fuel cells use this reaction to generate electricity. With the cell phone and gadget(小机件)market in mind, Medis has developed a fuel cell with cheap components that produces little heat and effortlessly reduces waste water without turning to energy consuming pumps.

Learning to save money when you"re young is an important lesson. All good lessons arid habits begin early, and saving is a skill that everyone needs. Many people—adults included—do not have a good sense of saving for the long run.
I have been lucky to learn this lesson early because I have had a grass-cutting business since I was 10 years old. Of the money I make I spend about 10 percent and save the other 90.
Making sure you save and don"t spend too much is a good way to build up wealth. I have put my earnings in a bank. Many teens I know spend all the money they earn so it never has a chance to grow. Young people should realize that their teenage years are a great time to begin saving.
At high school many parents pay for almost everything, so your expenses can be small. If you have a lob, you should have fun with some of the money. But you should also save some so that it will grow. Then you can begin planning for your future. When you spend money, you not only lose that money, but also lose the interest you could have earned by saving it.
After high school, college is expensive and then "real" life begins, with expenses such as food and rent. If you can hold onto a good percentage of the money you earn as a teen, going to college and buying a house will be much easier.________________, the more time the money has to grow. If you are in your thirties without any savings, you will always have to struggle. The earlier you begin saving, the easier it is to create a nest egg.
Later in life it can be hard to start saving because general costs of living are more expensive and you may only have enough to pay your bills. If you want to buy a house and have a family, you need money to start with, which comes from saving.
Many say money cannot make you happy, and this is true. But money can help you to lead a secure life.
Saving early will mean you will have to work for fewer years when you are older. It will also allow you to spend time doing the things that you want to do.
In addition to this, it will mean you can live the way you want to without worrying.

Most people want to know how things are made. They honestly admit, however, that they hardly know a thing when it comes to understanding how a piece of music is made. Where a composer （作曲家） begins, how he manages to keep going - in fact, how and where he leams his trade -all are covered in complete darkness. The composer, in short, is a man of mystery. （神秘）.
One of the first things the common man wants to know about is the part inspiration （灵感） plays in a composer" s work. He finds it difficult to believe that composers are not much interested in that question. Writing music is as natural for the composer as eating or sleeping for all. Music is something that the composer happens to have been born for.
The composer, therefore, does not say to himself: "Do I feel inspired?" He says to himself:
"Do I feel like working today?" And if he feels like working, he does. It is more or less like saying to himself: "Do I feel sleepy?" If you feel sleepy, you go to sleep. If you don"t feel sleepy, you stay up. If the composer doesn" t feel like working, he doesn" t work. It" s as simple as that.
小题1:What would be the best title for the text?| A．Composer: a man of mystery | | B．Practice makes good music | | C．Relation between sleeping and music | | D．Music: product of nature |
小题2: The words "covered in complete darkness" underlined in Paragraph I most probably mean| A．difficult to be made | | B．without any light | | C．black in color | | D．not known |
小题3: Most people seem to think that a composer _______ .| A．finds it difficult to write music | | B．considers it important to have a good rest | | C．should like to talk about inspiration | | D．never asks himself very simple questions |
小题4:The author will most probably agree that composers _______| A．are born with a gift for music | | B．are people full of mystery | | C．work late at night for their music | | D．know a lot about eating and sleeping |

So you"re between the ages of 13 and 24. What makes you happy? Spending time with family was the top answer to that open-ended question, according to an extensive survey--more than 100 questions asked of 1,280 people aged 13-24 -- conducted by The Associated Press on the nature of happiness among America"s young people.
Next was spending time with friends. And good news for parents: Nearly three quarters of young people say their relationship __________ makes them happy.
"They"re my foundation," says Kristiana St. John, 17, a high-school student from Queens in New York. "My mom tells me that even if I do something stupid, she"s still going to love me no matter what. Just knowing that makes me feel very happy and blessed."
Other results are more disconcerting. While most young people are happy overall with the way their lives are going, there are racial differences: the poll shows whites to be happier than blacks and Hispanics. A lot of young people feel stress, particularly those from the middle class, and females more than males.
You might think money would be clearly tied to a general sense of happiness. But almost no one said "money" when asked what makes them happy, though people with the highest family incomes are generally happier with life. However, having highly educated parents is a stronger predictor of happiness than income.
Overwhelmingly, young people think marriage would make them happy and want to be married some day. Most also want to have kids.
Finally, when asked to name their heroes, nearly half of respondents mentioned one or both of their parents. The winner, by a nose: Mom.

Every year 2.2 million tons of oil are spilled ( 散落，溅出 ) into the ocean. Actually, this only amounts to a small percentage of the total 1.6 billion tons of oil shipped around the world each year.However, this spilled oil has terrible effects on ocean life, including the coastlines where the off washes up onto shore. Some of the largest spills in history were caused by oil tankers running into each other or by an oil tanker sailing into shallow water and hitting the bottom of the ocean.
After these spills, officials try to discover who or what was at fault to help prevent similar accidents in the future.
One of the worst oil spills in history occurred along the Alaskan coastline in 1989. In this accident, 42,000 tons of oil spilled from a tanker which resulted in terrible damage to this sensitive natural area. In this spill, the tanker"s captain, who was tired from overwork and drinking alcohol, had gone to___________. He gave control of the ship to the third mate. The third mate was unfamiliar with the path the ship took, and he ran the ship onto Blighe Reef. Blighe Reef is a natural underwater rock wall near the Alaskan coast. Damaged by the reef, the ship leaked oil out into the ocean. More than 1,600 kilometers of coastline were affected by the oil spill. Some scientists who studied nature in the area guessed that 580,000 birds and 5,500 otters died when the oil from the spill covered their skin. As well, smaller shellfish and other sea creatures were later eaten by seals, whales, and other animals. The most oil ever spilled was actually dumped on purpose as an act of ecological warfare. The term ecological warfare means to fight by doing harm to nature in the area under attack. In 1990, Iraq sent soldiers into Kuwait and set off the Persian Gulf War. As part of the Iraq war plan,900,000 tons of oil were let out into the Persian Gulf Way Iraq. This oil covered 1,500 square kilometers of water in the Persian Gulf. The oil also damaged 650 kilometers of the coastline of both Kuwait and Saudi Arabia. In some places, oil floating on the water was measured to be 43 centimeters thick. Water birds, water plants, and baby fish were all seriously affected by the oil. The long-term effects of this act on the food chain in the area are bound to cause problems tar into the future.
