[单项选择]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 US Coast Guard to become a freelance writer (自由撰稿人), 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

[单项选择]Every profession or trade, every art, and every science has its technical vocabulary, the function of which is partly to designate things or processes which have no names in ordinary English, and partly to secure greater exactness in nomenclature. Such special dialects, or jargons, are necessary in technical discussion of any kind. Thousands of these technical terms are very properly included in every large dictionary, yet, as a whole, they are rather on the outskirts of the English language than actually within its borders.
Different occupations, however, differ widely in the character of their special vocabularies. In trades and handicrafts, and other vocations, like farming and fishery, that have occupied great numbers of men from remote times, the technical vocabulary, is very old. Hence, though highly technical in many particulars, these vocabularies are mole familiar in sound, and more generally understood, than most other technicalities. The special dialects of law, medicin

When we see well, we do not think about our eyes very often. (76) It is only when we cannot See perfectly that we realize how important our eyes are.
People who are near-sighted can only see things that are very close to their eyes. Everything else seems blurry (unclear). Many people who do a lot of work, such as writing, reading and sewing, become near-sighted.
People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm’s length, lf they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts(白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.
