Question

请认真阅读下面短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。

注意：每个空格只填一个单词。

WARNING: Holding a cellphone against your ear or storing it in your pocket may be dangerous to your health.

This paraphrases (解释) a warning that cellphone manufacturers include in the small print that is often taken for granted when a new phone is purchased. Apple, for example, doesn’t want iPhones to come closer to you than 1.5 centimeters. Research In Motion, BlackBerry’s manufacturer, recommends 2.5 centimeters.

If health issues arise from cellphone use, the results are serious. Voice calls—Americans chat on cellphones 2.26 trillion minutes annually—bring in $109 billion for the wireless carriers.

Devra Davis, who has worked for the University of Pittsburgh, has published a book about cellphone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.

Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cellphones arrived. But the average covers an increase in brain cancer in the 20-to-29 age group and a drop for the older population.

“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.

Children are more vulnerable (易受伤害的) to radiation than adults, Ms. Davis and other scientists point out. Radiation that enters the brain of an adult only five centimeters will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cellphone radiation and children, she says.

Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.

Ms. Davis recommends using wired headsets or the phone’s speaker. Children should send text message rather than call, she said, and pregnant women should keep phones away from the abdomen (腹部).

【解析】

这是一篇说明文。本文讲述的是手机辐射可诱发癌症，使用手机会带来辐射的负面影响，因此需要正确使用手机，特别是需要让孩子、孕妇等远离手机，为了健康，请远离手机。

1.

考查名词。根据第一段WARNING: Holding a cellphone against your ear or storing it in your pocket may be dangerous to your health.可知警告：把手机贴在耳朵上或放在口袋里可能会对你的健康造成危害。结合本文讲述的是手机辐射可诱发癌症，使用手机会带来辐射的负面影响，因此需要正确使用手机，特别是需要让孩子、孕妇等远离手机，为了健康，请远离手机。由此可知，文章的主题是与手机保持一定的距离（distance）。故填distance。

2.

考查名词的数。结合表格右边一栏内容可知，主要讲述的是要和手机保持距离的原因，应用名词reason，由several修饰，应用复数形式。故填reasons。

3.

考查名词。根据第五段中Over all, there has not been an increase in its incidence since cellphones arrived. But the average covers an increase in brain cancer in the 20-to-29 age group and a drop for the older population.可知总的来说，自手机出现以来，其发病率并没有增加。但平均数据显示，20至29岁年龄组的脑癌发病率有所上升，而老年人群的发病率有所下降。由此可知，20到29岁年龄组脑癌发病率增加。根据上文An，可知应填单数名词increase，表示“增加”。故填increase。

4.

考查动词。根据第六段 “Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer. 可知“大多数癌症有多种原因，”她说，但她指出，实验室研究表明，低能量辐射会损害细胞，从而可能导致癌症。由此可知，低能辐射会损伤细胞，可能导致癌症。表示“损害”，应用动词damage，且could后跟动词原形。故填damage。

5.

考查形容词。根据第七段中Children are more vulnerable (易受伤害的) to radiation than adults, Ms. Davis and other scientists point out.可知Davis女士和其他科学家指出，儿童比成年人更容易受到辐射的伤害。由此可知，儿童更容易受到辐射的伤害。表示“易受伤害的”，应填形容词vulnerable，作表语。故填vulnerable。

6.

考查动词时态。根据倒数第二段中Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.可知华盛顿大学生物工程系的研究教授Henry Lai从1980年开始在实验室进行辐射研究，他发现暴露在射频辐射下的老鼠大脑中的DNA受损。由此可知，暴露在射频辐射下的老鼠大脑中的DNA受损。表示“暴露”短语为expose to，此处为描述过去发生的事情，应用一般过去时。故填exposed。

7.

考查名词的数。根据表格右边内容可知，主要是说明如何解决手机对人产生危害的问题，即“解决方案”，应用复数名词solutions。单词首字母要大写。故填Solutions。

8.

考查名词的数。根据后文Make their warning markings larger.可知使它们的警告标记更大。由此可知，把手机的警告标记制作得更大，这属于制造商的解决措施。结合语境，表示“制造商”，应用复数名词manufacturers。单词首字母要大写。故填Manufacturers。

9.

考查形容词。根据最后一段中Ms. Davis recommends using wired headsets or the phone’s speaker.可知Davis建议使用有线耳机或手机扬声器。由此可知，一般人（common people）可以使用有线耳机或电话扬声器，来防止手机对身体产生危害。单词首字母要大写。故填Common。

10.

考查名词。根据最后一段中Children should send text message rather than call, she said, and pregnant women should keep phones away from the abdomen (腹部).可知她说，孩子应该发短信而不是打电话，孕妇应该让手机远离腹部。由此可知，孩子应该发短信而不是打电话，来防止手机对身体产生危害。单词首字母要大写。故填Children。
