Question

12．A dog's tail can tell you a lot more than you might think．Is it wagging（搖）to the left or is it wagging to the right？
"The direction of tail wagging does in fact matter，"said Giorgio Vallortigara，a professor at the University of Trento in Italy．Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog's state of mind-whether you're a human or another dog．
What's the difference between a left wag and a   right wag？Professor Vallortigara and his colleagues have studied 43 dogs of various breeds-German Shepherds，Beagles，Boxers，Border Collies and some mutts．They find that if a dog wags its tail to the left，it's feeling anxious or nervous．The reason could be an unfamiliar or dangerous situation，an unfamiliar person，or an unfamiliar and possibly threatening dog．But if the tail is wagging to the right，it means the dog is feeling relaxed and approachable．
"The tail is a very important signal，"said Thomas Reimchen，a biologist at the University of Victoria in British Columbia，Canada．"There is a lot of visual information that dogs use when communicating with each other．"
How did the scientists figure all this information out？They had the dogs in their study watch videotapes of other dogs．When the dog on the tape wagged its tail to the right，they say the other dogs remained calm and cool．But when the dog on the tape wagged its tail to the left，the other dogs got anxious．
The researchers are still not exactly sure if the direction of tail wagging is something the dog does consciously．They suspect that it might be something the dog does without even thinking about it-kind of like when you get goose bumps if something scares or startles you．They plan to do more research to get more information about what dogs are thinking and feeling while they're wagging．As Reimchen said，"I'm not going to be surprised if we find all sorts of really interesting processes that nobody has ever seen before．"

分析 狗的尾巴可以向你傳達(dá)比你能想到的更多信息．那么，關(guān)于狗的尾巴向左搖和向右搖都代表了什么呢？Vallortigara 教授和他的同事們做了研究調(diào)查顯示：狗的尾巴向左搖表示它感到焦急、緊張，向右搖代表它覺(jué)得放松和親切．生物學(xué)家Thomas Reimchen也對(duì)此發(fā)表了自己的觀點(diǎn)．但是，關(guān)于狗的尾巴搖的方向是否是其在有意識(shí)情況下做出的還有待調(diào)查研究．

解答 BDCA

 64．答案 B   細(xì)節(jié)理解題．從第二段的最后一句話"Professor Vallortigara finds that the way the tail is wagging can tell you a lot about a dog's state of mind-whether you're a human or another dog．"Professor Vallortigara發(fā)現(xiàn)狗尾巴搖動(dòng)的方向能告訴你很多狗的情感--不管你是人還是其它狗．可知選B．
65．答案 D  細(xì)節(jié)理解題．從第三段"They find that if a dog wags its tail to the left．it's feeling anxious or nervous．"知，他們發(fā)現(xiàn)如果狗的尾巴向左搖，它是覺(jué)得焦急和緊張．選D．
66．答案 C  細(xì)節(jié)分析題．在"There is a lot of visual information that dogs use when communicating with each other．"，由此可以看出，當(dāng)狗之間相互交流時(shí)，它們會(huì)看尾巴的搖動(dòng)情況，故選C．
67．答案 A   細(xì)節(jié)理解題．從全文來(lái)看，作者首先拋出一個(gè)問(wèn)題，然后介紹了關(guān)于這個(gè)問(wèn)題的科學(xué)研究來(lái)分析它．接著又提出科學(xué)家（第5段）是如何弄明白的呢，緊跟著就是對(duì)這個(gè)問(wèn)題的分析．所以呢，選項(xiàng)A問(wèn)問(wèn)題和分析問(wèn)題正確．

點(diǎn)評(píng) 1、要想做好科普英語(yǔ)閱讀理解題，同學(xué)們就要注意平時(shí)多讀科普知識(shí)類(lèi)文章，學(xué)習(xí)科普知識(shí)，積累常見(jiàn)的科普詞匯，從根本上提高科普英語(yǔ)的閱讀能力．
2、要熟悉科普類(lèi)文章的結(jié)構(gòu)特點(diǎn)．科普類(lèi)文章一般由標(biāo)題（Head line），導(dǎo)語(yǔ)（Introduction），背景（Back ground），主體（Main body）和結(jié)尾（End）五部分構(gòu)成．標(biāo)題是文章中心思想高度而又精辟的概括，但根據(jù)歷年的高考情況來(lái)看，這類(lèi)閱讀理解材料一般不給標(biāo)題，而要同學(xué)們選擇標(biāo)題．導(dǎo)語(yǔ)一般位于整篇文章的首段．背景交待一個(gè)事實(shí)的起因．主體則對(duì)導(dǎo)語(yǔ)概括的事實(shí)進(jìn)行詳細(xì)敘述，這一部分命題往往最多，因此，閱讀時(shí)，同學(xué)們要把這部分作為重點(diǎn)．結(jié)尾往往也是中心思想的概括，并與導(dǎo)語(yǔ)相呼應(yīng)，命題者常在此要設(shè)計(jì)一道推理判斷題．　　
3、在進(jìn)行推理判斷時(shí)，同學(xué)們一定要以閱讀材料所提供的科學(xué)事實(shí)為依據(jù)，同時(shí)所得出的結(jié)論還應(yīng)符合基本的科普常識(shí)．
