Article: Today, as in every other day of the year, more than 3,000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3,000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths due to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised. First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors beat that among female by nearly 10 percent . The statistic is reversing . Third, several recent studies have indicate high school _ have excessively high smoking rates, as much as 75 percent . Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking level among youth. Question: According to the author, the deaths among youth are mainly caused by _ . Options: A: traffic accidents B: smoking-related disease C: murder D: all of these

Read the article and select the best answer. Article: Donald was not very good at maths. He could not understand the teacher's explanations. Even when the teacher explained something a second time, Donald still could not understand it. "Never mind," Donald told himself. "I'm quite good at other subjects. I'll cheat in the maths exam, then I won't be in trouble." "I will sit next to the boy who's best at maths," he thought, "and copy down his answers." The day of the exam came, and Donald sat next to Brian Smith, who always was at the top of the class in maths. Donald carefully copied Brian's answers onto his own exam paper. At the end of the exam, the teacher collected the papers and graded them. Then she said, "Well, boys and girls. I've decided to give a prize to the student who got the highest grade. However, it's difficult for me to decide who to give the prize to, because two students, Doanld and Brian, got the same grade." "Let them share it," one of the other students said. "I have thought about that," the teacher said, "but I have decided to give the prize to Brian." Donald was angry when he heard this. He stood up and said. "That is not fair. I got the same grade as Brian." "That is true," the teacher said. "However, Brian's answer to Question 18 was 'I don't know,' while yours was 'Neither do I.'" Question: Donald got a high grade in maths because _ Options: A: maths was his best subject B: the questions were easy C: he copied from another boy D: the teacher explained the questions carefully

Read the article and select the best answer. Article: I got interested in the idea of standing desks about a year ago. The health advantages of standing instead of sitting for eight hours a day are clear, so when the company Ergotron invited me to review their WorkFit C-Mod Dual Desk, I jumped out of my chair---really. After several hours putting the desk together, I finally got to try it out. The standing desk had a desktop that I could use for writing. At first I absolutely loved it. Standing during the day instead of sitting was fantastic. Although I felt more tired after all that standing during the day, I knew the health benefits were worth the slight discomfort. However, after the initial novelty of the desk wore off, I realized that I could not use it in the long term. It was just not practical. While using the desk for a month , I could definitely foresee problems arising from using it full time. I enjoy having a lot of things on my desk. The standing desk just did not have enough room for all of my things. I can easily foresee awkward situations when I put that desk in an office space. When someone comes into your office, does your guest have to stand as well? If you office is big enough, maybe you have room for two chairs for you and a visitor, which is great. Yet for the ordinary worker in a small office, the standing desk creates a very awkward situation. Additionally, the amount of money I would have to spend to replace my current workspace with a standing desk was another issue. The desks I have looked at were highly expensive. Yes, spending the day standing can offset many of the negative effects of too much sitting, but we humans are designed for movement. Through activity changes like taking the stairs instead of the elevator, you can easily increase the time you spend on your feet. Best of all, those options are completely free. Question: According to the author, a standing desk _ . Options: A: takes up too much space B: is suitable for long-term use C: is cheaper than traditional desks D: is impractical though good for health
