8.Outdoor air pollution is an obvious danger because it's hard to miss.Auto gases,industrial waste,city smog-everyone knows they're a health hazard(危險(xiǎn)) and a call for solutions is on everyone's lips.But there's another threat just as perilous-a hidden threat(威脅) we are usually unaware of.We're speaking about the threat of indoor air pollution.
The dangers caused by indoor air pollution are too often underestimated(低估) and overlooked.According to a recent study,indoor air pollution can be many times higher than outdoor air pollution.A similar study by the Environmental Protection Agency shows that,in general,the air in our homes and offices is two to five times more polluted than outdoor air.
Scientific studies have found that indoor air pollution exacerbates(惡化) the symptoms of asthma(哮喘),and contributes to causing nausea(惡心),headaches and damage to the central nervous system.Evidence has even been found linking poor indoor air quality to certain cancers.Children who spend eighty percent of their time inside are particularly affected by indoor air pollution.
Cigarette smoke,chemical fertilizers,perfumes and clothing that has been dry-cleaned may contribute to indoor air pollution.Building materials-including paint and glue-are also contributors.
And homes aren't the only indoor areas affected by this danger.Offices are affected too-sometimes more so-with their copy machines and printers,inks and processing solutions (顯影液)and so on.
Fortunately there are many ways to reduce indoor air pollution and improve indoor air quality in your home and office.A major first step would be the use of an air purifier(凈化器).

解答 BDAB
29.B 猜測(cè)詞意題.根據(jù)everyone knows they're a health hazard(危險(xiǎn))可知,前文提到了一個(gè)危險(xiǎn),再接合there's another threat可知,"perilous"即危險(xiǎn)的 意思,故選B.
30.D 細(xì)節(jié)題.根據(jù)第二段開(kāi)頭The dangers caused by indoor air pollution are too often underestimated(低估) and overlooked.室內(nèi)空氣污染的危害經(jīng)常必備忽視,接著舉例子,目的是告訴我們室內(nèi)污染也很常見(jiàn)和嚴(yán)重,故選D.
31.A 細(xì)節(jié)題.根據(jù)文章Cigarette smoke,chemical fertilizers,perfumes and clothing that has been dry-cleaned may contribute to indoor air pollution.得知,抽煙是室內(nèi)污染的主要來(lái)源,故選A.
32.B 推理題.最后一段Fortunately there are many ways to reduce indoor air pollution…尤其是A major first step would be the use of an air purifier,所以接下來(lái)應(yīng)該重點(diǎn)介紹關(guān)于 purifier,故選B.
