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
