Article: Ever tried taking smart drugs to perform better in exams? They certainly work. Before last summer's exam, a few of my mates, merely out of curiosity, took a considerable amount of Modafinil, a drug normally used for narcolepsy . Guess what? While I was feeling sleepy, bored by revision, my mates were more focused. Modafinil is a smart drug that gives a user a feeling of staying awake for hours. It also sharpens the mind, improves memory and helps problem-solving. But it does more than just keeping you awake. It disturbs your mental system, making you desperate to do what you are doing. You just don't want to do anything else but revise all the time non-stop. A recent study discovers that healthy people use smart drugs, like Modafinil, to get down to and complete tasks they have been putting off, because these tasks seem more enjoyable when taking these drugs. This might sound like what a stressed student desires. However, the pills have a range of side-effects. "At present no evidence shows that these drugs are safe in healthy people," as a medical expert puts it, "Ordering online, though easy, is a dangerous way to obtain drugs. You never know what you're actually purchasing. " In my experience, Modafinil changes people's behaviour too. Over those weeks my friends became different people--in turn aggressive, cold. Even eating became "a waste of time" and so did conversation. A BBC survey found that of those who had tried smart drugs before, 92% would do so again. My friends say they'd happily do so without considering the practice a form of cheating. I admit I was curious--but not enough to try it. Seeing the strange behaviour of other users, I feel a little bit upset and scary. Modafinil may promise to change your grades, but it might also change the way you act. Don't say you haven't been warned!

Options: (A) escaping from reality (B) getting better exam results (C) curing their narcolepsy (D) leading an active life

Article: One day a student was taking a walk with his teacher. As they went along, they saw a pair of old shoes lying in the path. They were a poor farmer's, who was working in the nearby field. The student turned to the teacher, saying: "we will hide his shoes, and hide ourselves behind those trees, and wait to see what he will do." "My young friend," answered the teacher, "we should never make fun of the poor. Why not put a coin in each shoe, and then we will hide ourselves and watch?" The student did so and they both hid themselves behind the trees. The poor man soon finished his work, and came across the field to the path where he had left his coat and shoes. After putting on his coat, he put his foot into one of his shoes, and felt something hard. Then he bent down to feel what it was, and found the coin. Surprised, he looked at the coin, turned it around and looked at it again. He then looked around, but no person was seen. He put the money into his pocket, and continued to put on the other shoe. His surprise was doubled on finding the other coin. He couldn't control his feelings and fell to his knees, looked up to the sky and expressed his thanks. Then he spoke of his wife, sick and helpless, and his children without bread. He said the help would save them from dying. The student stood there deeply moved, and his eyes filled with tears. "Now," said the teacher, "are you not much happier than if you had hidden the shoes?"
Question: When the student saw the shoes, he wanted to _ .
Options: (A) steal them (B) find their owner (C) play a joke on the owner (D) give the owner some money

Article: The television news feature about Ben Heckmann, an eighth grader from Farmington, Minn, was breathless in its praise. "At 14, he has accomplished something many adults can't achieve," the reporter said, "Ben is a twice-published author." But Ben's two "Velvet Black" books, describing a fictional rock band, were not picked from a pile of manuscripts by an eagle eyed publisher. They were self-published, at the cost of $400 by Ben's parents. Over the past five years, print-on-demand technology and a growing number of self publishing companies whose books can be sold online have inspired writers of all ages to avoid the traditional gatekeeping system for determining who could call himself a "published author." The mothers and fathers who foot the bill say they are simply trying to encourage their children, in the same way that other parents buy equipment for a promising baseball player. But others see self-publishing as a lost opportunity to teach children about hardship and perseverance. Mr. Robbins, a critic, thinks it is wonderful to start writing at a young age, but worries self-publishing sends the wrong message. "There are no prodigies in literature," he said. "Literature requires experience, in a way that mathematics and music do not." Alan Rinzler, a publishing industry veteran, suggested parents hire a professional editor like him to work with their child to tear a manuscript apart and help make a better. Ben's father, Ken, said Ben's ambitions "weren't to knockHarry Potteroff the list," but "to get that good feeling inside that you've done something." Ajla Dizdarevic, 12, who has self-published two books of poetry, has been on television and in local newspapers. "Being a published author," she said, "was always a dream of mine." Her new dream: three books by age 15.
Question: Which of the following is true of Ben?
Options: (A) He has achieved something unusual for his age. (B) His self-published books were well received. (C) His manuscripts were favored by the publisher. (D) He was thought little of by the public media.
