Read the following article and select the best answer. Article: China's second manned space flight will be done by two astronauts over five days in 2005. "Shenzhou-VI will be sent into space sometime in 2005," said Zuo Saichun, a spokesperson of the China Aerospace Science and Technology (CAST). "The spacecraft will make new breakthroughs in China's manned space technology." Unlike Shenzhou-V, a little more than a year ago (in October, 2003), the next flight will see two astronauts fly in space for five days. Their capsule is designed to be capable of orbiting for a whole week, the spokesperson said. "For the first time, astronauts will enter and live in the orbital module of the spacecraft to do scientific experiments," said a statement from CAST. CAST did not say what those experiments will be. In Shenzhou-VI, scientists have changed the spacecraft's configuration to reduce its weight, and tried to improve the performance of on-board equipment. They have also worked to make sure of the energy supply of the spacecraft and further improve its safety. So far, scientists have worked out ways to solve problems on environmental control and life support. Shenzhou-VI will be sent into orbit atop a Long March 2F rocket. Meanwhile, a model of the Chang'e-1 satellite is expected to be sent to orbit the moon in two years. The satellite, part of the three-stage programme, would be followed by the landing of an unmanned vehicle on the moon in the second stage by 2010 and collecting samples of lunar soil by 2020 in the final stage, according to Sun Laiyan, director of the China National Space Administration. Question: According to the passage, the following problems should be solved before Shenzhou-VI is sent into space EXCEPT _ . - environmental control - energy supply - life support - lunar soil collecting
lunar soil collecting

Read the following article and select the best answer. Article: Have you ever wondered what you will be when you grow up? Perhaps you have thought of becoming an engineer or an environmentalist. 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.

Q: Read the following article and select the best answer. Article: Well, what a bonus! Lots of us are using technology to find rides, and not just to school. It's awkward to call a friend and ask for a ride, and half the time they'll say, "Sorry,my car is full." But with Twitter and Facebook, you just tweet Ashleys Pool Party and look for other people heading the same way. It may sound risky, but many teens stay within their own social circles to find rides, and don't branch out beyond friends of friends when asking on Twitter. For me, I only rideshare with people I know, but to some young people, especially those taking longer trips, stranger danger is less of a concern. The sharing economy got big during the recession . It allows people to access more goods and services using technology, while also allowing them to share cost. And that, technology, for me, is what the car was for my mom, a gateway to more freedom. According to the researchers at the University of Michigan,30 years ago, eight in ten American 18-year-olds had a driver's license. Today it's six in ten. So it's not that surprising that on my 16th birthday I wasn't rushing to get a license. All I wanted was an IPhone, Juliet Schor (Sociology professor at Boston College) knows people of my age love being connected and for young people driving means they have to disconnect from their technology, and that's negative. So if they could sit in the passenger side and still be connected, that's going to be a plus. To me, another plus is ridesharing represents something much bigger than trying to save money. I see it as evidence that people still depend on each other. My generation shares their cars and apartments the way neighbors used to share cups of sugar. For the system to work, we still need our own cars. But until I get my own version of the silver Super Beetle, you can find me on twitter. Question: Which is the best title for the passage? - Teens use Twitter to share rides. - Tips on reducing risks in rideshare - Cars are no longer a gateway to freedom. - New generation knows how to save money
A: Teens use Twitter to share rides.

Read the following article and select the best answer. Article: Spring is a wonderful season to celebrate rebirth and new life. The long, cold winter is over. The weather is warmer and sunnier. The trees again have leaves and the flowers are blooming. The season represents hope, joy and beauty. At this time, many people think of this classical music piece -- Spring, which shows happiness.
