When Wang Boxuan, a Beijing high schoolboy, uses up his exercise books, he does not throw them away. Each one is stored at his school with hundreds of exercise books given by other students. Then they are sold to a Beijing paper making factory. The paper is recycled and used again by students and teachers in the school. At the same time, the money made from the sales goes towards schools in Inner Mongolia for planting trees and grass. This place is one of the sources of the sandstorms that often attack Beijing during springtime. Wang's school is one of the schools in the capital that take part in the "Green Promise" --environmental protection activity. So far, nearly 210,000 students have taken part in the activity, collecting more than 87 tons of waste paper. Students are eager to help make the capital a more pleasant place. Question: Which is the best title for the passage? Options: A: Planting Trees. B: Green Promise. C: Collecting Waste Paper. D: Making Money.

A handshake or a pat on the shoulder is enough to convey our friendship or affection to one another.So when our newly-acquainted Western friends reach out in preparation for a hug, some of us feel awkward. Many questions go through our head. Where should I put my arms? Under their armpits or around their neck? What distance should I maintain? Should our chests touch? It's even more difficult with friends from some European countries. Should I kiss them on the cheek while hugging? Which side? Or is it both cheeks? Which side should I start on? But it isn't just people from cultures that emphasize a reservedness in expressing physical intimacy  who find hugging confusing. Hugs can cause discomfort or even distress in people who value their personal space. In a recent article for The Wall Street Journal, US psychologist Peggy Drexler said that although the US remains a "medium touch" culture -- "more physically demonstrative than Japan, where a bow is the all-purpose hello and goodbye, but less demonstrative than Latin or Eastern European cultures, where hugs are strong and can include a kiss on both cheeks", Americans do seem to be hugging more. From politicians to celebrities, hugs are given willy-nilly to friends, strangers and enemies alike; and the public has been quick to pick up the practice. Public figures know that nothing projects like the ability as a good hug. US First Lady Michelle Obama has put her arms around icy foreign leaders like Russian Prime Minister Dmitry Medvedev and the Queen of England, on the latter occasion actually breaking the rule of royal manners. But not all are grateful to be embraced, even by the most influential and famous. To them, any hug is offensive if it's not sincere. Amanda Hess, writing for US magazine Slate, says public figures should stop imposing hugs on everyone they meet. For them, a hug is rarely a gesture of sincere fellowship, compassion or affection. It's all part of a show. Hugs are falsely intimate power plays used by public... Question: The example of US first lady Michelle Obama is given to show that   _  . Options: A: Americans hold a "medium touch "culture B: public figures know hugging functions well in public C: she is much liked by American people D: hugs are forbidden in England

Article: Invented in Turkey and patented by Nanopool, a German company, the spray-on liquid glass might become one of the most useful inventions in the field of nanotechnology. The product was tested at the Saarbrucken Institute for New Materials.  It is worth mentioning that the invention is transparent and non-poisonous. The liquid glass can protect any type of surface from damages caused by water, UV radiation, dirt, heat, and bacterial infections. Besides, it is flexible and breathable, which means that the liquid glass can be applied on plants and seeds as well. Researchers found that the spray greatly increases the resistance of plants to bacteria-caused diseases. The trials also showed that the sprayed seeds grew faster.  Depending on the type of surface that is to be covered, researchers can add water or ethanol to the spray. Scientists say that  _ . The spray produces a coating that is just 100nm thick. Trials by food processing plants in Germany have concluded that foods covered with the glass can store longer than those stored in normal condition. According to Neil McClelland, UK project manager with Nanopool, due to its capabilities, the spray-on liquid glass can become one of the most useful inventions around the world, ending up being used by a lot of industries that will cover their products. At present, the invention is being used by a train company and a hotel chain in the UK, as well as a hamburger chain in Germany that are carrying out tests of the liquid glass for various uses.  The spray-on liquid glass was also tested in a Lancashire hospital, where it showed "very promising" results, being used to cover medical equipment and bandages. The invention could be also used on clothing, because it cannot be seen by the naked eye, thus clothes could become stain resistant. Due to its unique characteristics, the liquid glass can be used to cover bathrooms, sinks and many other surfaces in the home. According to the researchers, the spay-on glass can last for a year. It is expected to hit the DIY stores... Question: Which of the following about the liquid glass is NOTtrue? Options: A: We can still see an object clearly covered with the liquid. B: It will cause plants to have some kind of disease. C: Plants still have access to oxygen when covered by it. D: It can speed up the growth of seeds.
