n) ozone is “bad” when it is at ground level. ozone is a very reactive gas that is hard on lung tissue. it also damages plants and buildings. any ozone at ground level is a problem. unfortunately, chemicals in car exhaust and chemicals produced by some industries react with light to produce lots of ozone at ground level. in cities, the ozone level can rise to a point where it becomes hazardous to our health. that’s when you hear about an ozone warning on the news.

1. when ultraviolet rays from the sun separate an oxygen molecule into two single oxygen atoms in the stratosphere, the combination of a single oxygen atom and an oxygen molecule forms ozone.

2. you can make ozone test strips by yourself to find out about ozone levels in your own locale.

3. long-time exposure to ozone is badly harmful to our respiratory system.

4. chemicals in industrial waste gas and vehicle exhaust react with light to form lots of ozone at ground level.

5. internal combustion engines and power plants cause the artificial tropospheric ozone, also known as “bad” ozone.

6. ozone is very helpful because it absorbs uv radiation and separates us from it.

7. using gasoline-powered lawn equipment in the late spring, summer and early fall may increase ozone pollution.

8. ozone pollution occurs in urban and suburban areas as well as in rural areas.

9. in order to decrease ozone pollution, the epa has set up more rigorous air-quality standards.

10. pay close attention to the air quality index in your area every day can keep you away from ozone exposure.

文章主要介绍了什么是臭氧，臭氧污染的形成、危害，以及臭氧有利的一 面。文章还具体介绍了如何自己手工制作检测仪;如何避免暴露在臭氧之下;如 何预防和减少臭氧污染等。

1. b 本题答案的信息来自b段的倒数第二、三句话。原文中提到太阳紫外线将 氧分子分成了两个单独的氧原子，氧原子与氧分子再结合就生成了臭氧。 题干正好表达了这个意思。ultraviolet rays即是原文中的ultraviolet light。

2. e 本题答案的信息来自e段第一句话。题目中的find out about意为“弄清有关 的情况”，和原文中的detect and monitor含义相对应;题目中的inyour own locale和原文中的in your own backyard相对应。

3. f 本题答案的信息来自f段。f段提到人吸入臭氧后，它可以贯穿你的呼吸系统。接着提到它可能损害细支气管、肺部等呼吸系统的部位，故可知长期 暴露在臭氧下有损呼吸系统。

4. n 本题答案的信息来自n段第五句话，题干是对本句的同义转述。

5. c 本题答案的信息来自c段的第二句话。原句中先说“果”后说“因”，题目将

“因”提前，然后说“果”;原文中的man-made与题干中的artificial相对应; 原文中的termed与题干中的known as相对应。

6. m 本题答案的信息来自m段第二句和最后一句话。原文中第二句话首先提到

ozone is “good” when it is in the stratosphere.，在最后一句中提到臭氧为什 么有益;原文中的beneficial与题干中的helpful相对应;题目中的separates from对应原文中的prevents from。

7. j 本题答案的信息来自j段第一、二、三句话。原文中j段的首句提到有几种可以降低臭氧污染的.方法，接下来提到的一种方法是do not use gasoline- powered lawn equipment during these times.由此推测using gasoline-powered lawn equipment会导致臭氧污染增加;而由第二句话可推测出原文中的 during these times指的是in the late spring, summer and early fall。

8. d 本题答案的信息来自d段第一句话。原文提到臭氧污染主要在城市和城市郊区出现，但因为风和汽车、卡车运输的作用，农村也会发生臭氧污染， 题干是对此的归纳。

9. k 本题答案的信息来自k段第一句话。原文中的initiated和题目中的set up属于同义转换;原文中的stringent替换为了rigorous;原文中的reduce ozone pollution替换为了decrease ozone pollution。

10. h本题答案的信息来自h段第一句话。题目中的keep you away from对应原文的protect yourself from;题目中的pay close attention to 对应原文的should be aware of。
