1.As many as one in five US teenagers have some degree of hearing loss(喪失),according to researchers.They say the problem is growing.
"Teenagers really don't pay attention to how much noise they are exposed to(接觸),"Josef Shargorodsky of Brigham and Women's Hospital in Boston told Reuters."Often people won't notice it,but even very little hearing loss may influence language development,"said Shargorodsky,one of the researchers.
The study compared surveys from the early 1990s and the mid-2000s.Each included a few thousand teenagers.In the first survey,about 15percent of teenagers had some degree of hearing loss.Some 15years later,that number had risen by a third,to nearly 20percent.
"This certainly is big news,"said Alison Grimes,an ear doctor."Hearing loss is very common in old people,"Grimes said,but she added that it was worrying to see it happen in the younger age group.
In babies and young children,hearing problems are known to slow language development.The science is less clear for teenagers,but it is easy to imagine how being hard of hearing could influence learning,said Grimes.
The reasons for the rise are still unclear.When researchers asked teenagers about noise exposure-on the job,at school or from activities,for example-the teenagers didn't report any change.But Shargorodsky said that might not be true."We know from before that it is difficult to ask this age group about noise exposure-they underestimate it.."Few people would call it noise when they listen to music on their MP3player,for example."There is a difference between what we think is loud and what is harmful to the ear,"said Grimes.
Although it's not clear that the MP3players cause teenagers'hearing loss,Grimes said it was still a good idea to turn down the sound and take short breaks from listening.

分析 【文章主旨】這是一篇科普知識類閱讀,短文主要講的是有多達五分之一的美國青少年有一定程度的聽力損失,而且問題還越來越嚴重.然后作者就根據(jù)這一現(xiàn)象展開了對近年來青少年聽力情況的分析,文章還引用了研究員的話以及研究結(jié)果,并說出了聽力受損的危害.
解答 57.A 細節(jié)理解題,根據(jù)最后一段Grimes said it was still a good idea to turn down the sound and take short breaks from listening可知把聲音調(diào)低并且從聽力中休息對我們來說是個好主意,故選A.
58.B 推理判斷題.根據(jù)倒數(shù)第二段Few people would call it noise when they listen to music on their MP3player,for example."There is a difference between what we think is loud and what is harmful to the ear,"said Grimes.例如,很少有人在當他們用MP3播放器聽音樂時認為那是一種噪音."對于我們所認為的對耳朵什么是響亮的和什么是吵鬧的是有區(qū)別的."格蘭姆斯說.由此可知,青少年是在不知不覺中聽力減退的,因為他們對噪音和響亮的聲音沒有敏感的認知.故選B.
59.A 推理判斷題.根據(jù)倒數(shù)第三段In babies and young children,hearing problems are known to slow language development.The science is less clear for teenagers,在嬰幼兒時期的孩子,聽力問題被認為會延緩語言方面的,這個結(jié)果對于青少年卻不太清楚,可知青少年也有可能會因為聽力問題而使語言能力遲緩.題中A選項中有may,所以符合文意,故選A.
60.C 主旨大意題.根據(jù)題中選項可知A選項:一個簡短的文字;B選項:一篇來自青少年的報道;C選項:一個響而亮的教訓;D選項:一封來自MP3使用者的信.縱觀全文,可知文章主要講的是有關(guān)青少年聽力下降的現(xiàn)象,這個結(jié)果是對人的一個關(guān)于耳朵教訓,告誡我們要多注意保護耳朵,不要總處在響而亮的環(huán)境中.故選C.
點評 考查學生的細節(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,再做出正確選擇.在做推理判斷題時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.
