8.Retired nurse Sue Collins was just beginning the second length of her local pool when her morning swim suddenly became anything but a pleasure.
Two months ago Sue,69,who has never suffered from asthma or any other breathing problem in the past,suddenly found herself hard for breath.
"I felt as if my throat and oesophagus(食道)were closing up,"says Sue.
Sue is convinced the problem is related to the indoor swimming baths."I spend half the year in Turkey and swim every day outside in a pool or the sea there and never have this problem,"she says.
She may be right,because although a trip to the pool is the perfect exercise for many,the chlorine (氯氣)used to keep the water free from germs can lead to problems.
But in most cases it's not the chlorine that causes problems,but the by-products formed when chlorine interacts with other substances-and this is mostly due to people not showering before they enter the pool.
"This then poisons the water for them and for others,"says Dr.Hull."The chlorine interacts with sweat and urine(尿素)on the skin and forms by-products called chloramines that float above the surface as a gaseous solution that can be inhaled in."
Chloramines are heavier than air so hang over the water where they are easily breathed in.Some believe they may cause lung disorders.A Swedish study in 2013 examining the health of 146workers at 46indoor pools found that 17per cent had airway trouble at work-but no problems at home.
As Dr.Hull says:‘People need to remember that showering isn't just for them.It is for the greater good.'

分析 本文屬于說明文閱讀,作者通過這篇文章主要向我們描述了在游泳前為什么要洗澡的原因,洗澡是為了阻止氯和汗水和尿液之間的相互作用對皮膚的傷害
解答 32.C.細節(jié)理解題.根據(jù)第三段Sue is convinced the problem is related to the indoor swimming baths可知蘇突然患哮喘在一個室內(nèi)游泳池;故選C.
33.B.細節(jié)理解題.根據(jù)第四段because although a trip to the pool is the perfect exercise for many,the chlorine (氯氣)used to keep the water free from germs can lead to problems可知把氯放進池子里的水里是為了殺死水中的細菌;故選B.
34.A.細節(jié)理解題.根據(jù)文章The chlorine interacts with sweat and urine(尿素)on the skin and forms by-products called chloramines that float above the surface as a gaseous solution that can be inhaled in可知在游泳池里游泳前先洗個澡是為了阻止氯和汗水和尿液之間的相互作用對皮膚的傷害;故選A.
35.D.推理判斷題.根據(jù)最后一段:‘People need to remember that showering isn't just for them.It is for the greater good可知這篇文章的目的是告訴人們在游泳前為什么要洗澡;故選D.
點評 考察學生的細節(jié)理解和推理判斷能力,做細節(jié)理解題時一定要找到文章中的原句,和題干進行比較,再做出正確的選擇.在做推理判斷題不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進行合乎邏輯的推理判斷.
