Questions 46 to 50 are based on the following passage.
Like fine food，good writing is something we approach with pleasure and enjoy from the first taste to the last.And good writers，like good cooks，do not suddenly appear full-blown.Quite the opposite，just as the cook has to undergo a particular training，mastering the skills of his trade，the writer must sit at hisdesk and devote long hours to achieving a style in his writing，whatever its purpose is—schoolwork，matters of business，or purely social communication.
You may be sure that the more painstaking the effort，the more effective the writing，and the more rewarding.
There are still some faraway places in the world where you might find a public scribe to do your business or social writing for you，for money. There are a few managers who are lucky enough to have the service ofthat rare kind of secretary who can take care of all sorts of letter writing with no more than a quick note to work from.But for most of us，if there is any writing to be done，we have to do it ourselves.
We have to write school papers，business papers or home papers.We are constantly called on to put words to papers.It would be difficult to count the number of such words，messages，letters，and reports put intomails or delivered by hand，but the daily figures must be extremely large.What is more，everyone who writes expects，or at least hopes whatever he writes will be read，from first word to last，not just thrown into some “letters-to-be-read” files or into a wastepaper basket.This is the reason we bend our efforts toward learning and practicing the skills of interesting，effective writing.

47.[D] 原文第2段首句提到，这种public scribe会帮你写商业文件或社会交流文章，但他们也会收费的，D与之相符A中的secretary应该是不收贵的，故排除;D中的machine与文中的remote places不相符，故也可排除。
49.[C] 文章第3段倒数第2句的大意是：我们希望自己写的东西能被人从头到尾地读，能不被扔进“letters-to-be read” file，且根据下文的a wastepaper basket可推测这里说的是希望自己写的东西不被忽视，故本题应选C.
50.[A] 由文章的结尾的this is the reason，知道作者有“解释”的目的，同时他说“我们要尽最大的努力学习和练习有趣、有效地写作的技巧”，可知有persuade(说服)的目的，故选A.
