​Section B​Directions: In this part there is a passage followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice.​​Many a young person tells me he wants to be a writer. I always encourage such people, but I also explain that there’s a big difference between “being a writer” and writing. In most cases, these individuals are dreaming of wealth and fame, not the long hours alone at a typewriter. “You’ve got to want to write,” I say 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 (自由撰稿者), I had no prospects at all. What I did have was a friend who found 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 manual typewriter and felt like a genuine writer.​​After a year or so, however, I still hadn’t gotten a break and began to doubt myself. It was so hard to sell a story that barely made enough to eat. But I knew I wanted to write. I had dreamed about it for years. I wasn’t going to be one of those people who die wondering, What if? I would keep putting my dream to the test, even though it meant living with uncertainty and fear of failure. This is the Shadowland of hope, and anyone with a dream must learn to live there.​​​21. The passage is meant to ________. ​​
