　　Directions: There are 20 blanks in the following passage. For each blank there are four choices marked [A],[B],[C] and [D] on the right side of the paper. You should choose the ONE that best fits into the passage. Then mark the corresponding letter on Answer Sheet 2 with a single line through the center.

　　Every year more than half a million American kids have drainage (排泄) tubes surgically implanted in their ears to combat persistent infections. The procedure, know as tympanostomy, may not be as 62 as the tonsillectomy was in the 1940s, but it now 63 as the nation's leading childhood 64 and a new study suggests it's being vastly overused. In 65 more than 6,000 scheduled ear tube operations, a team of experts 66 by Harvard pediatrician Lawrence Kleinman found that fewer than half were clearly justified. "Each year", the researchers write in the current Journal of the American Medical Association (JAMA), "several hundred thousand children in the United States may be 67 tympanostomy tubes that offer them no demonstrated 68 ...and may place them at increased 69 ."

　　Tube placement isn't a 70 risky procedure, but it costs $1,000 to $1,500 and sometimes scars the eardrum, causing a partial loss of 71 . Studies show that the benefits are most likely to 72 the risks if a child's middle ear has produced sticky fluid 73 more than four months despite treatment 74 antibiotics. For less virulent infections, drug treatment is usually a(n) 75 , safer alternative (though drugs, too, can be overused). In the new JAMA study, Kleinman's team reviewed the medical charts of 6,429 kids, all under 16, 76 doctors had recommended the procedure. Even making "generous assumptions" about the likely 77 , the researchers found that a quarter of the proposed operations were 78 , since less invasive alternatives were available, 79 another third were as likely to harm the recipients as help them.

　　Parents needn't 80 about ear tubes that are already in place. Once 81 implanted, the tiny devices provide drainage for six months to a year, then come out by reducing health costs by hundreds of millions of dollars every year.

　　2010年6月大学英语四级考试全真预测试卷五答案详解

　　Part I Writing

　　To Be a Small Fish in a Big Pond or a Big Fish in a Small Pond?

　　There are distinct differences between being a small fish in a big pond and a big fish in a small pond, so it is with working as a subordinate in a large enterprise and presiding in a small firm.

　　With the former, you can derive a deep sense of satisfaction from being a member of a well-known organization such as General Motors, or the Bell. You have the opportunities of learning from experienced executives and knowing about the standard working process.

　　With the latter, you have greater responsibilities and your decision may bring immediate effect. Normally you are exposed to various experiences and expected to do a great many things without much help or guidance, which will indeed improve your abilities.

　　Personally I prefer to work in a small firm, where I have great prospect of promotion as long as I work hard. And I'm sure I'll become an important figure within my small pond.

　　Part II Reading Comprehension (Skimming and Scanning)

　　1. N 结合标题To Save Trees, Fighting One Alien Insect with Others迅速扫读全文可知，文章主要不是描写HWA这种虫害本身，而是如何防治这种虫害，故题干表述不正确。

　　2. Y 根据题干中的信息词hallmark和Appalachia's national parks定位原文，第三段明确指出The evergreen trees, a hallmark of southern Appalachia's national parks...，可知题干表述正确。

　　3. Y 根据题干中的信息词HWA定位原文，第四段有Already the tiny bug from Japan, known as the hemlock woolly adelgid (HWA)...，可知题干表述正确。

　　4. Y 题干中有acting quickly, 与一小标题同，估计答案在其下段落下。定位到第二段，发现题干是文中原句，故题干表述正确。

　　5. N 根据题干中的信息词An infected tree定位原文，在Acting Quickly下的倒数第二段段末有An infected tree usually dies within five years of initial attack，可知题干表述错误。

　　6. NG 文章后半部分讲到为了控制HWA，美国已在受灾部分地区投放HWA的天敌St bettles，但是在文章倒数第二段末尾指出这种方法是否有效还无法判断(too early to measure their impact)，故本题表述正确与否末可知。

　　7. N 在对抗HWA的方法中，文章着重介绍了引入其天敌来达到生态平衡的方法，且在Plans of Attack下的第四段段首有明确说明，故题干表述错误。

　　8. 15 U.S. states。根据题干中的信息词1951定位原文，在Acting Quickly下第一段可找到答案。

　　9. another type of infestation。读完原文，发现Risky Business下讲了用St bettles来控制HWA这种方法可能带来的风险，而题干正是谈的这种方法，定位Risky Business下的段落，首段即可找到答案。

　　10. keep HWA in check。最后一题多出现在文章末尾，根据题干中的信息词year-round定位Risky Busines下的段落，在第三段第一句可以找到答案。
