Have you ever been frustrated (沮丧的) when left talking to yourself after your mobile phone battery runs out in the middle of a call? If yes, then here comes some good news. Scientists are now perfecting a way to recharge (充电) electrical equipment while on the move.
Researchers from the Netherlands, France and Portugal announced last week that they have developed very thin solar panels (太阳能板) that can be put on clothes. They can also be added to furniture and rooftops. They change light from the sun into electricity.
In about three years, you'll be able to wear a jacket that will recharge your phone as you walk. For camping fans, the development could lead to a tent which charges batteries all day so you can have light or music at night.
The basic technology of wearable solar panels is the same as that used for conventional (传统的) solar panels. Pairs of sheets of semi-conducting silicon (半导体硅) are linked together to form the panel.
But scientists made them much thinner by using different silicon. At one micrometre, they are the same thickness as photographic film.
"This technology will make it easier for people to use clean energy sources," said Gerrit Kroesen, a physicist in the Netherlands who led the team of scientists.
But the thin panels are not as efficient as the thicker ones. While some solar panels now operate at an efficiency of about 20 per cent, the new flexible (柔韧的) panels are only 7 per cent efficient. But the scientists believe that this is worth accepting for a stronger and more useful panel.
But the thinner panel is cheaper. An A4 sized panel put onto the back of a jacket costs less than US$13. It could charge a cell phone during a summer walk in the countryside. As long as you stay within range of the transmitting masts (发射天线) that relay a call to the networks, phones will never again run out of power.

The terrible college entrance exam is not only a big challenge (挑战) for Chinese high school students, but also a very important exam in the lives of South Korean students.
Although the long, cold winter has already started in South Korea, the annual (一年一度的) national exams have made the atmosphere very heated.
More than 675,000 South Korean high school graduates took the college entrance exam last Wednesday. They usually take exams in Korean, maths, sociology (社会学), history and foreign languages.
Officially there is one college place for every 1.33 students. But because all the students want to go to the top universities in the country, the competition can reach one place for 10 students. The students want to attend these colleges for both their famous names and better job opportunities.
Because students face fierce competition, they have to study very hard to realize their dreams. Park Seung said he and his classmates often go to school before 7:30 a.m. After school has finished at 6:30 p.m., most of them go to the library to continue their study instead of returning home. Since many libraries in South Korea are open 24 hours a day, they often stay long into the night. Many of the Senior 3 students only sleep for three to four hours a day. “I feel a lot of pressure, but I have to study very hard in order to make my dream come true. This is my lifetime goal and it will be a turning point in my life which could decide my future,” Park said.
The exam day is a very serious day for the whole of South Korea. Vehicles are not allowed within a 200-metre radius (范围) of all the test sites to make sure the students have quiet surroundings. Tooting (吹奏) of horns is forbidden, even airplanes are ordered to avoid landing and take-off near the test sites during listening comprehension test hours.
Students are told their scores in December before they apply for college. This is followed by face-to-face oral tests. There are public and private universities in South Korea. Many private universities are well-known, but their fees can be 18, 000 yuan each term. This has made a lot of students think again.
1.We can infer that there are almost ________ college places for high school graduates.
A. 675, 000 B. 507, 520 C. 500, 000 D. 600, 000
2.The students want to study in top colleges mainly because ________.
A. they can succeed more easily in future B. they can learn more
C. they can make more money D. it is interesting to study there
3.Before students are allowed to colleges ________.

Air quality in Shanghai worsened last week compared with the previous week, according to the latest report from the Shanghai Environment Monitoring Centre.
The average air pollution index (API) for sulphur dioxide (SO2) remain almost unchanged from the previous week, but the APIs for nitrogen oxide (NOx) and total suspended (悬浮) particles (TSP) rose by 35 and 27 percent. The overall quality still belonged to class 2 category. Nitrogen oxide, caused mainly by vehicle exhaust and burning of cooking gas, was still the major pollutant of the week.
The Shanghai Environmental Monitoring Centre operates six automatic air monitors in the city’s Putuo, Yangpu, Luwan, Hongkou, Jing’an and Xuhui districts.
