Batteries are included, but the charger’s not. The Nokia E-Cu concept phone doesn’t need to plug in; it charges from any heat source. Designer Patrick Hyland says it can even work off the warmth of your pocket. The first time“it would take approximately seven hours to reach full charge, then after that it’s continuously charging by keeping the phone in areas between 86 degrees and 104 degrees Fahrenheit. ”That’s one hot pocket.
He’s put a thermo generator(热偶发电器)inside the phone that transforms heat into electric potential energy. To better conduct the heat to that little power plant in your pocket, the E-Cu(E for energy, Cu for copper)is coated by copper backing with heat sinks like those normally used to keep electronics from overheating.
Nokia doesn’t have current plans to build the phone, so for now it remains a concept. But Hyland says he’s open to anyone who wants to cooperate.
For Americans this technology would certainly be convenient. It would also save a bit on energy bills and waste. ”Annually, unwanted phone chargers produce 51, 000 tons of waste in addition to the greenhouse gases created by the production of the electricity needed to charge them, ”Hyland says. So a charger-free phone is also a green phone. Though adapting our plug-in habits would help a group of people, most cell phone related energy use comes from leaving your charger plugged in all day unnecessarily.
The real potential for charger-free cell phone technology is what it could enable places where plugging in isn’t an option, like rural areas in the developing world.
Cell phones are spreading faster than power lines and bringing with them countless opportunities, aid and health advances. A phone like the E-Cu, if it ever comes to be, would enable all manner of expanded aid and development by phone projects. Let’s hope Patrick finds a partner.

Diana Jacobs thought her family had a workable plan to pay for college for her 21-year-old twin sons: a combination of savings, income, scholarships, and a modest amount of borrowing. Then her husband lost his job, and the plan fell apart.
“I have two kids in college, and I want to say ‘come home’, but at the same time I want to provide them with a good education.” says Jacobs.
The Jacobs family did work out a solution. They asked and received more aid from the schools, and each son increased his borrowing to the maximum amount through the federal loan (贷款) program. They will each graduate with $20,000 of debt, but at least they will be able to finish school.
With unemployment rising, financial aid administrators expect to hear more families like the Jacobs. More students are applying for aid, and more families expect to need student loans. College administrators are concerned that they will not have enough aid money to go around.
At the same time, tuition（学费）continues to rise. A report from the National Center for Public Policy and Higher Education found that college tuition and fees increased 439% from 1982 to 2007, while average family income rose just 147%. Student borrowing has more than doubled in the last decade.
“If we go on this way for another 25 years, we won’t have an affordable system of higher education,” says Patrick M. Callan, president of the center. “The middle class families have been financing it through debt. They will send kids to college whatever it takes, even if that means a huge amount of debt.”
Financial aid administrators have been having a hard time as many companies decide that student loans are not profitable enough and have stopped making them. The good news, however, is that federal loans account for about three quarters of student borrowing, and the government says that money will flow uninterrupted.How did the Jacobs manage to solve their problem?
| A．They asked their kids to come home. |
| B．They borrowed $20,000 from the school. |
| C．They encouraged their twin sons to do part-time jobs. |
| D．They got help from the school and the federal government. |
Financial aid administrators believe that .
| A．more families will face the same problem as the Jacobs |
| B．the government will receive more letters of complaint |
| C．college tuition fees will double soon |
| D．America’s unemployment will fall |
What can we learn about the middle class families from the text?
| A．They blamed the government for the tuition increase. |
| B．Their income remained steady in the last decade. |
| C．They will try their best to send kids to college. |
| D．Their debts will be paid off within 25 years. |
According to the last paragraph, the government will .
| A．provide most students scholarships |
| B．dismiss some financial aid administrators |
| C．stop the companies from making student loans |
| D．go on providing financial support for college students |

Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.
Born in September, 1897, Irene Curie was the first of the Curies’ two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.
Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities（设备）to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognized in the form of a Military’s Medal by the French government.
In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.
Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity（辐射能）. Irene Joliot-Curie died from leukemia on March 17, 1956.Why was Irene Curie awarded a Military Medal?
| A．Because she received a degree in mathematics. |
| B．Because she contributed to saving the wounded. |
