Passage Two
Why do we cry? 【第14題答案位置】Can you imagine life without tears? Not only do tears keep your eyes lubricated,they also contain a substance that kills certain bacteria so they can't infect your eyes.Give up your tears,and you'll lose this on?the?spot defense.Nobody wants to give up the flood of extra tears you produce when you get something physical or chemical in your eyes.Tears are very good at washing this irritating stuff out.Another thing you couldn't do without your tears is cry from joy,anger,or sadness.Humans are the only animals that produce tears in response to emotions.【第17題答案位置】And most people say a good cry makes them feel better.Many scientists,therefore,believe that crying somehow helps us cope with emotional situations.【第15題答案位置】Tear researcher,William Fred,is trying to figure out how it happens.“One possibility”,he says,“is that tears discharge certain chemicals from your body,chemicals that build up during stress.”When people talk about crying it out,“I think that actually might be what they are doing,”he says.
If Fred is right,what do you think would happen to people who restrain their tears? Boys,for example,cry only about a quarter as often as girls once they reach teenage years.【第16題答案位置】And we all cry a lot less now than we did as babies.Could it possibly be that we feel less stress? Maybe we found other ways to deal with it,or maybe we just feel embarrassed.

譯文:
我們?yōu)楹味奁?你能想象沒有眼淚的生活嗎?眼淚不僅能保持眼睛濕潤,而且淚水中還含有一種能夠殺死某些細菌的物質,因此它能保護眼睛不受這些細菌的感染。放棄眼淚,你就會失去一種現(xiàn)成的防護方式。當一些物理或化學物質侵入眼睛時,沒有人愿意放棄所能產生的額外淚水。淚水可以很好地將這種使人難受的物質排出。當你由于開心、生氣和悲傷而哭泣時,淚水的另一項不可替代的功能便體現(xiàn)了出來。人類是唯一一種受情感影響會流淚的動物。而且大多數(shù)人稱痛快地哭一場能讓自己感覺好一些。因此,許多科學家相信,在某種程度上哭泣能幫助我們處理情感問題。淚水研究員威廉·弗雷德正試圖弄明白這種現(xiàn)象是如何發(fā)生的。他解釋道:“淚水能排出身體承受壓力時積聚的某種化學物質,這可能是原因之一。每當人們說“哭出來吧”,“我認為或許這就是他們正在做的事情?!彼f。
如果弗雷德是正確的,對于那些強忍淚水的人們來說,情況會怎么樣?例如十幾歲的男孩,他們哭泣的次數(shù)只相當于同齡女孩的四分之一。還有我們所有人現(xiàn)在哭泣的次數(shù)要遠遠少于嬰幼兒時期。難道是因為我們面對的壓力少了嗎?或許我們找到了其他方式來應對壓力,又或許我們僅僅是對哭泣感到難堪而已。
解析:
科普知識說明文。
14.B事實細節(jié)題。首句群出題?!癢hy do we cry?”即為該題答案,選項B.Why people cry.為原文的同義替換。
15.D事實細節(jié)題。因果關系出題,定位詞為therefore。文中提到...crying somehow helps us cope with emotional situations.視聽基本一致,結合同義替換,可知答案為D,其中tears對應原文中的crying,emotional problems對應原文中的emotional situations。
16.C事實細節(jié)題。需要抓住選項中的提示詞boys,girls等。文中提到Boys,for example,cry only about a quarter as often as girls once they reach teenage years.由此可知十幾歲的男孩子哭泣的次數(shù)只相當于同齡女孩的四分之一,也就是女孩子哭的次數(shù)是男孩子的四倍,答案為C。
17.A事實細節(jié)題。亂序??疾椤白罡呒壖疤厥庠~定位”,即“only”。文中提到Humans are the only animals that produce tears in response to emotions.視聽基本一致,結合同義替換,可知答案為A,其中respond to是原文中in response to的同義替換,而shedding tears是原文中的produce tears的同義替換。
