5．Every day we experience one of the wonders of the world around us without even realizing it．It is not the amazing complexity of television，nor the impressive technology of transport．The universal wonder we share and experience is our ability to make noises with our mouths，and so transmit ideas and thoughts to each other's minds．This ability comes so naturally that tend to forget what a miracle（奇跡）it is．
Obviously，the ability to talk is something that marks humans off from animals．Of course，some animals have powers just as amazing．Birds can fly thousands of miles by observing positions of the stars in the sky in relation to the time of day and year．In Nature's went show，humans are a species of animal that have developed their own special act．If we reduce it to basic terms，it's a ability for communicating information to others，by varying sounds we make as we breathe out．
Not that we don't have other powers of communication．Our facial expressions convey our emotions，such as anger，or joy，or disappointment．The way we hold our beads can indicate to others whether we are happy or sad．This is so-called"body language"．Bristling（直立的）fur is an unmistakable warning of attack among many animals．Similarly，the bowed bead or drooping tail shows a readiness to take second place in any animal gathering．
Such a means of communication is a basic mechanism that animals，including human beings，instinctively acquire and display．Is the ability to speak just another sort of instinct？If so，how did human beings acquire this amazing skill？Biologists can readily indicate that particular area of our brain where speech mechanisms function，but this doesn't tell us how that part of our bodies originated in our biological history．

72．According to the passage，the wonder we take for granted isA．
A．our ability to use language
B．the miracle of technology
C．the amazing power of nature
D．our ability to make noises with mouth
73．What feature of"body language"mentioned in the passage is common to both humans and animals？D
A．Lifting heads when sad．
B．Keeping long faces when angry．
C．Bristling hair when ready to attack．
D．Bowing heads when willing to obey．
74．What can be inferred from Paragraph 3？D
A．Body language is unique to humans．
B．Animals express emotions just as humans do．
C．Humans have other powers of communication．
D．Humans are no different from animals to some degree．
75．This passage is mainly aboutC．
A．the development of body language．
B．the special role humans play in nature．
C．the power to convey information to others．
D．the difference between humans and animals in language use．

分析 本文是介紹關(guān)于人類使用語(yǔ)言的能力的說(shuō)明文，主要闡述人區(qū)分動(dòng)物的特殊能力及其相似性． 每天我們?cè)跊]有意識(shí)到的時(shí)候我們經(jīng)歷一個(gè)世界奇跡，那就是我們用嘴巴發(fā)出聲音并能傳播思想和思考對(duì)方的想法的能力，這種能力過于平常往往忘記這個(gè)奇跡．說(shuō)話的能力是標(biāo)志人類與動(dòng)物的區(qū)別，有些動(dòng)物一樣有驚人的能力，人類是一種已形成了自己特殊的行為的動(dòng)物，它是通過我們呼吸時(shí)發(fā)出的不同的聲音與他人交流信息的一種能力．還可以通過肢體語(yǔ)言來(lái)溝通交流，人類大腦的特定區(qū)域語(yǔ)言機(jī)制功能使得人類能獲得驚人的技能．

解答 72．A   細(xì)節(jié)理解題．根據(jù)第一段倒數(shù)第二句話"The universal wonder we share and experience is our ability to make noise without mouths，and so transmit ideas and thoughts to each other's minds"可知，我們把使用語(yǔ)言的能力這個(gè)奇跡當(dāng)做理所當(dāng)然．B，C選項(xiàng)與文章不符，在第一段第二句話中可得知．D選項(xiàng)易誤導(dǎo)學(xué)生，在文章中雖然有原話，但一句話沒有說(shuō)完，關(guān)鍵是通過嘴巴發(fā)出的聲音去給其他人傳遞信息．所以D選項(xiàng)也是錯(cuò)誤的，故選A． 
73．D  細(xì)節(jié)理解題． 根據(jù)第三段最后一句話"Similarly，the bowed head or drooping tail shows ….."可知，樂意服從時(shí)低頭是人類和動(dòng)物共同的肢體語(yǔ)言．A和B選項(xiàng)描繪的是人的肢體語(yǔ)言特征．C 選項(xiàng)描繪的是動(dòng)物的肢體語(yǔ)言．故選D．
74．D   推理判斷題．根據(jù)第三段后三句話"The way we hold our beads can indicate to others whether we are happy or sad．This is so-called"body language"．Bristling（直立的）fur is an unmistakable warning of attack among many animals．Similarly，the bowed bead or drooping tail shows a readiness to take second place in any animal gathering．"可知，人類在某種程度上和動(dòng)物沒有不同．從段落中可得知A，B，C 均與文章不符． 故選D．
75．C   主旨大意題． 整篇文章談?wù)摰亩际墙o他人傳遞信息的力量，使用語(yǔ)言的能力．A，B選項(xiàng)文章未提及．D選項(xiàng)較片面，文章第三段中提到了相似點(diǎn)和差異二種． 故選C．

點(diǎn)評(píng) 解答細(xì)節(jié)理解題時(shí)，一個(gè)常用的方法就是運(yùn)用定位法，即根據(jù)題干和選項(xiàng)中的關(guān)鍵詞從原文中找到相關(guān)的句子，與選項(xiàng)進(jìn)行比較從而確定答案；推理判斷題既要求學(xué)生透過文章表面文字信息推測(cè)文章隱含意思，又要求學(xué)生對(duì)作者的態(tài)度、意圖及文章細(xì)節(jié)的發(fā)展作正確的推理判斷，力求從作者的角度去考慮，不要固守自己的看法或觀點(diǎn)．
