　　改革后的大学英语四级阅读新增的长篇阅读题型，是段落信息匹配题。篇章后附有10个句子，每句一题。每句所含的信息出自篇章的某一段落，要求考生找出与每句所含信息相匹配的段落。有的段落可能对应两题，有的段落可能不对应任何一题。以下是小编为大家整理的2014年段落信息匹配题练习，供各位考生参考。　　Words: 1,103How Ozone Pollution Works　　A) The weather report on the radio or TV tells you that it is going to be
sunny and hot and that an orange ozone alert has been issued. What is ozone?
What does an orange alert mean? Why should you be concerned about it? In this
article, we will examine what ozone is, how it is produced, what health hazards
it poses and what you can do to reduce ozone pollution.　　B) Ozone is a molecule of three oxygen atoms bound together (O3). It is
unstable and highly reactive. Ozone is used as a bleach, a deodorizing agent,
and a sterilization agent for air and drinking water. At low concentrations, it
is toxic. Ozone is found naturally in small concentrations in the stratosphere,
a layer of Earth’s upper atmosphere. In this upper atmosphere, ozone is made
when ultraviolet light from the sun splits an oxygen molecule (O2), forming two
single oxygen atoms. If a freed atom collides with an oxygen molecule, it
becomes ozone. Stratospheric ozone has been called “good” ozone because it
protects the Earth’s surface from dangerous ultraviolet light.　　C) Ozone can also be found in the troposphere, the lowest layer of the
atmosphere. Tropospheric ozone (often termed “ bad ” ozone) is man - made, a
result of air pollution from internal combustion engines and power plants.
Automobile exhaust and industrial emissions release a family of nitrogen oxide
gases (NOx) and volatile organic compounds (VOC), by-products of burning
gasoline and coal. NOx and VOC combine chemically with oxygen to form ozone
during sunny, high- temperature conditions of late spring, summer and early
fall. High levels of ozone are usually formed in the heat of the afternoon and
early evening, dissipating during the cooler nights.　　D) Although ozone pollution is formed mainly in urban and suburban areas,
it ends up in rural areas as well, carried by prevailing winds or resulting from
cars and trucks that travel into rural areas. Significant levels of ozone
pollution can be detected in rural areas as far as 250 miles downwind from urban
industrial zones.　　E) You can make ozone test strips to detect and monitor ozone levels in
your own backyard or around your school. You will need corn starch, filter paper
(coffee filters work well) and potassium iodide (can be ordered from a science
education supplier such as Carolina Biological Supply or Fisher Scientific).
Basically, you make a paste from water, corn starch and potassium-iodide, and
you paint this paste on strips of filter paper. You then expose the strips to
the air for eight hours. Ozone in the air will react with the potassium iodide
to change the color of the strip. You will also need to know the relative
humidity, which you can get from a newspaper, weather broadcast or home weather
station.　　F) When you inhale ozone, it travels throughout your respiratory tract.
Because ozone is very corrosive, it damages the bronchioles and alveoli in your
lungs, air sacs that are important for gas exchange. Repeated exposure to ozone
can inflame lung tissues and cause respiratory infections.　　G) Ozone exposure can aggravate existing respiratory conditions such as
asthma, reduce your lung function and capacity for exercise and cause chest
pains and coughing. Young children, adults who are active outdoors and people
with respiratory diseases are most susceptible to the high levels of ozone
encountered during the summer. In addition to effects on humans, the corrosive
nature of ozone can damage plants and trees. High levels of ozone can destroy
agricultural crops and forest vegetation.　　H) To protect yourself from ozone exposure, you should be aware of the Air
Quality Index (AQI) in your area every day—you can usually find it in the
newspaper or on a morning weather forecast on TV or radio. You should also be
familiar with the U.S. Environmental Protection Agency (EPA) guide for
ozone-alert values.　　I) What do the numbers in the AQI mean? The AQI measures concentrations of
five air pollutants: ozone, sulfur dioxide, particulate matter, carbon monoxide
and nitrogen dioxide. The EPA has chosen these pollutants as criteria
pollutants, but these are not all of the pollutants in the air. These
concentrations are compared to a standard set out in federal law. An index value
of 100 means that all of the criteria pollutants are at the maximum level that
is considered safe for the majority of the population. To reduce your exposure
to ozone, you should avoid exercising during afternoon and early evening hours
in the summer.　　J) There are several ways you can help to decrease ozone pollution. Limit
using your automobile during afternoon and early evening hours in the late
spring, summer and early fall. Do not use gasoline-powered lawn equipment during
these times. Do not fuel your car during these times. Do not light fires or
outdoor grills during these times. Keep the engine of your car or boat tuned.
Make sure that your tires are properly inflated. Use environmentally safe
paints, cleaning and office products (some of these chemicals are sources of
VOC).　　K) Besides personal attempts to reduce ozone pollution, the EPA has
initiated more stringent air-quality standards (such as the Clean Air Act and
its modifications) to reduce air pollution. Compliance with these standards by
industries, manufacturers and state and local governments has significantly
reduced the levels of many common air pollutants.　　L) With continued conservation and reduction practices, adherence to
ozone-pollution warnings, research and government regulation, ozone-pollution
levels should　　continue to fall. Perhaps future generations will not be threatened by this
environmental pollutant.　　M) The thing that determines whether ozone is good or bad is its location.
Ozone is ‘‘good，，when it is in the stratosphere. The stratosphere is a layer of
the atmosphere starting at the level of about 6 miles (about 10 kilometers)
above sea level. The stratosphere naturally contains about six parts per million
of ozone, and this ozone is very beneficial because it absorbs UV radiation and
prevents it from reaching us.　　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.　　文章精要　　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。　　答案解析　　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
题目中的Pay close attention to 对应原文的should be aware of。

（全名 M330 Silent Plus）是罗技在今年柏林消费电子展上发布的全新一代超静音鼠标，当时看到新闻说这款鼠标在手感不变的情况下点击噪声比一般鼠标（罗技是拿它跟自家的M170对比）减少了至少90%，当时看完就觉着罗技真心屌啊，在想知道人家用了啥黑科技好奇心的驱使下，想都没多想就在奶茶东首发时抢购了一只回来（本想海淘，可是等的时间比较久，而且可能国内无法保修，于是放弃了这个想法），今天下午刚收到货，边拆机边拍照，一个人好辛苦！ && 东哥家同时还上架了另一款新款静音鼠标：，咱也成功抢到了一只，拆完 M330 ，我都佩服我自己真是“勤快”~~~~ && 更新试用视频，建议大家把音量稍微开大点，不然有可能听不到微动的声音。
&&罗技新一代鼠标的包装盒设计很简约，一些重要特色都印在了正面，让你一眼就能知道这款鼠标有哪些与众不同的地方。&&&&&&M330 电池续航最长24个月，无线连接范围最远10米，传感器分辨率 1000dpi，使用优联即插即忘超微型接收器。 && M330属于低端产品，所以外盒也做得十分“抠门”，毫无霸气可言。 && M330 真身登场。 && 跟 M220 放一块比比大小，看起来差不多。 && M330 带电源指示灯（刚开机或快没电才会亮），M220 啥灯都莫有，还没来得及看配套软件有没有电量显示功能。&& &&还是大鼠标握感更舒适。 && 里面也是够简单的，便宜就该这样？ && 照片被压缩一下画质差好多，白瞎了我的“好”相机。
&& 光电传感模块,负责把光电信号转换成数字信号。 && 这单薄的小板子，不敢太用力捏着，生怕给捏碎了。 && NRF 31512C 主控。 && 凯华的机械编码器。 罗技称这款鼠标应用了高性能材料制成的垫片和橡胶滚轮，可确保在滑动鼠标和滚动滚轮时安静无声。 && 跟
一样，M330 也是滑盖式电池盖，稍用力一扒就打开了，这点很好，有些鼠标的电池盖卡得过紧，用上洪荒之力都难以打开。
