1. 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 attributed 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 exceeded that among female by nearly 10 percent. The statistic is reversing. Third, several recent studies have indicate high school dropouts 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 levels among youth. 1. According to the author, the deaths among youth are mainly caused by _____. A. traffic accidents B. smoking-related diseases C. murder D. all of these 2. Every day there are over _____young people who will become regular smoker. A. 75 B. 23 C. 30 D. 3,000 3. By "dropout" (in paragraph 3) the author means______. A. students who failed the examination

大学英语3作业题及答案

精品文档阅读理解题分第1题 (20) Many a young person tells me he wants to be a writer. I always encourage and such people, but I also explain that there's a big difference between a writerwriting. In most cases these individuals are dreaming of wealth and fame, not the long hours at a typewriter. “You have got to want to write,”I said to them, “not want to be a writer.” The reality is that writing is a lonely, private and poor-paying affair. For every writer kissed by fortune there are thousands more whose longing is never rewarded. When I left a 20-year career in the U.S. Coast Guard to become a freelance writer, I had no prospects at all. What I did have was a friend who found for me my room in a New York apartment building. It didn't even matter that it was cold and had no bathroom. I immediately bought a used typewriter and felt like a genuine writer. and began to doubt After a year or so, however, I still hadn't got a breakmyself. It was so hard to sell a story that barely made enough to eat. But I knew I to write. I had dreamed about it for many years. I wasn't going to be one wanted of those people who died wondering. What if? I would keep putting my dream to test (even though it meant living with uncertainty and fear of failure). This is the shadow-land of hope, and anyone with a dream must learn to live there. ．阅读理解1 (4.0) 分 The passage is meant to _______ . warn young people of the hardship that a successful writer has to experience 、A advise young people to give up their idea of becoming a professional writer B、 show young people it is unrealistic for a writer to pursue wealth C、 D、encourage young people to pursue a writing career 2．阅读理解 (4.0) 分 What can be concluded from the passage? 精品文档． 精品文档 rewarding. ａｎｄ、Genuine writers often find their work interesting A
