Question: Question: Read the article and select the best answer. Article: 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. Question: The passage is mainly about   _  . Options: 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: Read the article and select the best answer. Article: 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... Question: What can be learned about Start School Later? Options: 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".

Question: Read the article and select the best answer. Article: Today I find myself in one of the safest cities in the world, Singapore. But the truth is, even here in Singapore, security cannot be taken for granted. It is a small nation that has no natural resources to speak of, even something as basic as water is constantly threatened to be cut off by Malaysia. Months after the September 11thattacks on US oil, a plot to bomb American soldiers near their military base in Singapore was uncovered by the local authorities. The United Nations has tried for more than half a century to architect peace for the world. But it has clearly failed. The grand horrors of the World Wars may have stopped but only in the forms they had existed before. When the enemy is unseen and there are no front lines, have we in fact created a more peaceful and secure place? Where have we gone wrong? Perhaps it is because the international body has never understood that peace was, is, and will never be something it can manage. Not recognizing this truth, the methods it provides are often short-lived and some even dangerous. Solutions for threatening situations tend to require the countries to carry out economic and political reforms so that they will become idealized democratic society like America or Britain. The UN fails to consider that hundreds of years of evolution gave rise to these strong democracies. So the result is further chaos and corruption, worse for all. Actually, an international organization or a government cannot possess peace to give away, but there are those who do possess it. Those who own peace are us, as individuals who cherish life, not our own but all others'. The act of achieving peace lies in us when we choose to respect social and cultural differences and appreciate that all our lives are fragile.

Options: A: Singapore isn't rich in natural resources B: Singapore was involved in catching those who launched the September 11th attack C: Singapore also has problems with security D: Malaysia possesses a threat to Singapore
