Question: With fifteen years Britain and other nations should be well on with the building of huge industrial complexes   for the recycling of waste. The word "rubbish" could lose its meaning because everything which goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else. The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant   for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well. Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: First, it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that rollers will break up everything that can be broken. Finally, the rubbish will pass under magnets  , which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the final stage. The first full-scale giant recycling plants are perhaps fifteen years away. Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long. The passage is mainly about   _  . A) a cheap way to get energy B) the location of recycling plants C) new ways of recycling wastes D) the probability of city environment
Answer: C

Question: Good news for middle and high school students. When it comes to sleeping a little longer, physicians are on your side. On Monday, the American Academy Pediatrics  announced its recommendation that middle and high schools start at 8:30 a.m.or later. "Doing so will match school schedules to the biological sleep patterns of adolescents," the AAP writes in a press release regarding its new policy statement called "School Start Times for Adolescents" . "Chronic  sleep loss in adolescents is one of the most common public health issues in the U.S.today," according to Judith Owens, director of Sleep Medicine at Children's National Health System. "The research is clear that adolescents who get enough sleep have a reduced risk of being overweight or suffering depression, are less likely to be involved in automobile accidents, and have better grades, higher standardized test scores and an overall better quality of life," Owens said in the press release. "Studies have shown that delaying early school start times is one key factor that can help adolescents get the sleep they need to grow and learn." Even before the AAP's announcement, school districts across the country have been rethinking start times. Earlier this year The New York Times wrote about Dos Santos, a student at Rock Bridge High School. When Dos Santos learned that school officials were considering starting school 30 minutes earlier than the existing time, she became worried.The student gathered others to her cause. In the end, school officials decided against the earlier start time. One of the organizations that Dos Santos reached out to for help was Start School Later, a nonprofit organization that focuses on getting public schools to set "healthy school hours." "It's going to take collective action, perhaps on a national scale, to get many districts to take on this issue," Terra Ziporyn Snider, PhD, director and co-founder of Start School Later, told Yahoo Health. "The science is clear, the will to change isn't," she explained. "The reason for that is... What can be learned about Start School Later? A) Dr.Snider is director of this nonprofit organization. B) It is a commercial organization belonging to Yahoo Health. C) It helps private schools to set healthy schedules for students. D) It made a policy called. 'School Start Times for Adolescents".
Answer: A

Question: Colin walked slowly home from school. He looked across the hills at the little Irish fishing village. It did not seem like Christmas Eve. Perhaps this was because it still had not snowed. But Colin knew there was another reason--a reason he did not dare whisper even in his heart.  He looked toward the sea. There was no ship. And seven days ago his father's fishing boat hadn't gone home in time. "I'll bring you a small sheep dog from the Shetland Isles," Colin's father told him the morning he left. But now it was Christmas Eve. Colin looked toward the lighthouse, high on the hill. For seven days, there had been no light to guide his father's ship.  Colin pushed open the door of his cottage. "We'll need more peat   for the fire, Colin," said his mother as he entered. "It has burned itself out. And it's near time to light the Christmas candle. Everybody in Ireland lights a candle on Christmas Eve, even when there's sadness in the house. It shows that your house and heart are open to strangers. I've two candles, one for each of us. If you gather some peat, we'll be ready for supper soon." Colin nodded and went outside.  He led their donkey up the hill. But while he was staring at the lighthouse, Colin had an idea. He came to the lighthouse and knocked on the door.  Mr. Duffy, the keeper, opened the door. "What's up, young man?" "Mr. Duffy," said Colin, "what did you use to light the lighthouse?" "Well, we used an oil lamp. But we've no oil to burn." "Maybe kerosene   would do," suggested Colin.  "Well, I suppose," Mr. Duffy thought. "But you wouldn't find even a little spare kerosene in this village. Everyone is so poor ..." Colin was gone before Mr. Duffy could finish his sentence.  He ran back to the cottage. Then he ran out with four buckets. Colin could see candles glowing in nearly every cottage in the valley. A candle on Christmas Eve meant that a stranger would be welcome and given whatever he asked. He didn't stop running until he came to the first house.  "Could you spare me just a half cup of kerosene... What would be the best title for the passage? A) Colin's Christmas candle B) A particular Christmas Eve C) A light in Colin's heart D) A father's fishing experience
