Question: Article: Most students hate their endless homework. The students from Class 2, Senior 2 of the High School Affiliated to Peking University certainly did so before they published their own collection of English novels at home. Their small book contains stories about a holy war, the happy life of a self-taught artist and the story of a laid-off worker who devoted his last breath to playing his beloved accordion . The book becomes an instant hit on campus. About 3,000 copies have been sold and the class is already working on the second volume. "We're up to our ears in homework. Exercises and exams make us out of breath. But to do something creative and full of imagination is such a great achievement," said Yu Xiaoxiao, 16. "I took the writing as an ordinary homework at the beginning, but after I finished the first part of my story, I could not help but let it flow," said Wang An, who wrote "Accordion". Inspired by "Lord of the Rings", Jiang Lu wrote his story about magic wins between angels from the light and the dark side. "The main message of the story was to look at the balance of the world. Both dark and light angels fight with love as their weapons. I want to tell people that selfish love might bring hate," Jiang said. "I was shocked by their work and felt so proud to be the editor of my students' book," said Nathaniel Timmermann, the oral English teacher at the school. Liu Xiuqin, an English teacher, started the project by asking students to write whatever was in their mind every week. "They have performed beyond expectation," Liu said. "They wrote interesting stories and their English has improved after they started to express their real minds." "We never imagined that our homework would be so popular and profitable . We sell the novels at five yuan, but many teachers pay more to encourage us," said Yuan Mengyao.
Question: After Wang An finished the first part of his story, he _ .

Question: Article: James Proud, a British businessman who settled in San Francisco launched a Twitter campaign called "Stop DST". Daylight Saving Time (DST) refers to the time during the summer when clocks are one hour ahead of standard time. "Daylight saving was created to save energy, and it doesn't really do that." Proud said, "but what's even worse are its negative health effects. It's both outdated and harmful." daylight saving has been linked to a surprising number of health issues such as heart attacks, but Proud has a particular interest in the topic because of its disruptive effects on sleep. Last year, German researchers suggested that our body cocks never really adjust t daylight saving, which causes a host of health problems. Till Roenneberg of Ludwig-Maximillians University said that because of DST, "the majority of the population has severely decreased productivity, decreased quality of life, increasing chance of getting illness, and is just plain tired." The week after daylight saving also witnesses a sudden increase in fatal traffic accidents, according to the University of Colorado. It is believed that this is caused both by disrupted sleep schedules and the shift of daylight hours from the morning to the evening. "Daylight saving is an economic tradition. And all economic choices involve achieving a balance. " said behavioral economist David Gerard. "Even if we decide to abolish daylight saving, there would be a large number of unhappy people." Some such people are shift works, students and parents of schoolchildren, all of whom get to enjoy an extra hour of daylight after work or class with DST. Plus, restaurants love the extra evening sales DST allows. Daylight saving has also been linked to lower crime rates, due to the "deterrent effect" of longer daylight. Basically, more light increase a criminal's chances of being seen by witnesses or police, which discourages criminal activity. Gerard also point out that an extra hour of daylight has vastly more influence in the American South, where the sun sets earlier, even in the summer, than in the north. That's why residents of southern states may values DST more.
Question: What causes Proud's greatest concern?
Options: (A) DST not keeping up with economic development (B) DST resulting in disorder in people's sleep schedule (C) DST stopping people from working productively. (D) DST not helping to save energy any more

Answer: B

Question: Article: A teddy bear from Cumbria is launching into space to raise cash for charity . Terence, an experienced traveller who has been to Iraq, will be the guest of honour on aviation legend Burt Rutan's Spaceship One when it flies above Earth. The mission takes off from California on September 29, and on his return the cuddly toy will be auctioned off in aid of the North Air Ambulance Appeal . Spaceship One is the world's first private spacecraft, and is competing for a prestigious space travel prize. Chief executive of the Great North Air Ambulance Service (GNAAS), Graham Pickering, said "flying officer" Terence had been handed over to the RAF six months ago and staff had been receiving postcards from him ever since. He said, "Terence was a fundraising idea that really took off. We have received pictures of him in a U2 craft, trying parachuting and even looking drunk and disorderly. When the RAF finally discharge him he will be a very rare bear indeed--we just hope he does not burn up on re-entry to Earth." GNAAS, which needs charitable donations of more than PS2m a year, has three air ambulances . Peter Bond, spokesman for the Royal Astronomical Society, said Terence's safety was not guaranteed. He said, "This is a new and experimental craft and this will only be the second time it has flown. During its first voyage it developed technical problems but hopefully they have now been resolved." Since May, Terence has spent time with members of 100 Squadron based at RAF Leeming in Basra, Iraq, and at air shows with performing fighter planes. Spaceship One will fly 100km (62 miles) above the Earth's surface, just breaking through the planet's atmosphere. If it repeats the feat inside two weeks, it will claim the $10m Ansari X-Prize set up to encourage the private space flight business.
