Article: Across the United States, universities and colleges have been looking to become more sustainable and more than 600 schools have already planned to become eco-friendly. The EcoDorm, home to 36 students at Warren Wilson College in Swannanoa, was designed to be sustainable from top to bottom, or in this case, from its rainwater-collection system to its garden. The dormitory is bringing new meaning to the concept of living "green" at college. At Warren Wilson College, a biological science school with fewer than 1,000 students, the sustainability drive came from the student body. The EcoDorm concept was presented ten years ago by two students; a planning committee firstly suggested using building materials like corncob. Although the architects disagreed with the idea, they came up with other creative solutions: Wood siding was taken from the trees grown in the school yard that were suffering from a disease, and rainwater was collected in an old railway car and pumped back into the house to clean the toilets. All in all, the dorm uses nearly two-thirds less electricity than a similar-sized traditional building world. But even the most sustainable homes need continued efforts from its livers. And in the case of EcoDorm, students live by their words. Most also take advantage of the dorm's bio-garden, planting and harvesting fruits and vegetables. "I didn't have to worry about paper towels being wasted or feel bad about drying my clothes outside," Jeremy Lekich, the dorm's gardener, said. "Basically, it has made my life easier." Question: We can learn from the text that the EcoDorm in the US _ . - offers students the chances to have a natural living at college - was firstly built by two college students - was designed for saving building materials - is only applicable in few schools
offers students the chances to have a natural living at college

Read the following article and select the best answer. Article: It is estimated that some seven hundred million people, about half the world's adult population, are unable to read or write, and there are probably two hundred and fifty million more whose level is so slight that it is hardly called literacy . Recently the attack on illiteracy had been stepped up. A world plan has been drawn up by a committee of UNESCO experts in Paris, as part of the United Nations Development Decade ,and an international conference of the subject has also been held. UNESCO stresses that functional literacy is the aim. People must learn the basic skills of responsible citizenship, the ability of reading notices, newspapers, timetables, letters, price-lists to keep simple records and accounts, to select the importance of the information gathered, and to fill in the forms. The major areas of illiteracy are in Asia, Africa, and Central and South America. In Africa there are at least one hundred million illiterate people, which is eighty to eighty-five percent of the total population. In Europe the figure is about twenty-four million; most of them are in Sothern Europe, with Spain, Italy, Portugal, Yugoslavia heading the list (the United Kingdom has about seven hundred thousand). UNESGO is eager for each country in the world, poor or rich, to wipe out illiteracy. Question: The author implies that this world plan is to _ . - be carried out in the major areas of illiteracy like Africa. - be realized in the years - be drawn up by Parisian experts - be discussed at an international conference
be realized in the years

Read the following article and select the best answer. Article: As skies are filled with millions of migrating birds, European scientists say the seasonal wonder appears to be strange: The fatter the bird, tile better it flies. The results of their study led to a theory opposite to a central one of aerodynamics , which says that the power needed to fly increases with weight. For birds, obviously, the cost of flying with heavy fat is much smaller than we used to think. Researchers found that red knot wading birds double their normal body weight of 100 grams before making their twice-a-year nonstop flight between the British Isles and the Russian Arctic. Distance: 5,000 kilometers. Another study in the magazine Nature measured the advantage of flying in an aerodynamic group which allows birds to save energy by flying smoothly and quietly in the lead bird' s air stream. Flying in groups, their heart rates were 14.5 percent lower than flying alone, according to Henri, a French scientist. The findings help explain how birds complete difficult migrations. Researchers had thought that thinner, stronger birds would have the best chance to survive. The first study suggests that building up fat to be burnt as fuel during the migration is worth more than the energy it takes to carry the additional weight. In the study, researchers said their team studied the birds flown at different body weights during 28 simulated flights. They forced a small amount of special water into the birds' bodies so that they could measure the amount of energy burnt during the flight. Question: A _ red knot wading bird has a better chance to survive during its migrating flight. - stronger - weaker - thinner - fatter
fatter

Read the following article and select the best answer. Article: A friend asks you to be a volunteer. Your husband asks you to glance over an e-mail he is writing to his boss. You say you'd love to. Really! But..."I don't have time". It seems plausible( ). We're all busy these days, right? But there are reasons not to use these four words, at least with yourself. Here's the big one: _ is not true. You tell yourself "I don't have time" to exercise, but we all have 168 hours a week. If someone offered to pay you $100,000 a week to go to the gym for 5 of those 168 hours, you would probably find the time to do it. Since that isn't going to happen, this is a more exact description: " It's not a priority ." There are a million things we could be doing with our time; some are priorities and some are not, even if it's wrong to say so. Try it. "I'm not going to read to you tonight, sweetie, because it's not a priority. Daddy's present priority is to check my e-mails." Using the words "I don't have time" keeps us from admitting to the fact that how we spend our time is a choice. It puts the responsibility for our lives on someone else: a boss, a client or a family member. Better to be truthful: "I have another volunteer job on which I am focusing my energy right now. It is the cause that is most important to me." Or, to your husband "I wish you had mentioned this earlier. Right now, my priority is to get our children dressed and out of the door for school. I will be available around lunch time if you would like to talk". Question: You can find this text in the _ section of a newspaper. - sports - entertainment - culture - science
