17.THE human face doesn't lie.We show sadness and happiness through our expressions.But exactly how many emotions can our face make?Scientists used to believe we had six basic facial expressions that tell others how we feel:sad,happy,surprised,fearful,angry and disgusted (惡心的).
But a new study shows that our faces can do more than we think.Scientists from Ohio State University found out that humans can actually make 21different facial expressions after studying how people move their facial muscles.
The scientists took pictures of 230volunteers making faces in response to different cues (提示).?These cues included phrases like"you just got some great unexpected news",which produced a"happily surprised"reaction from volunteers.Other cues included"you smell a bad odor (氣味)",which caused"disgusted"faces.
In total,around 5,000pictures were taken of the volunteers.The scientists then studied similarities of these pictures using a computer expression database.This helped them to define a facial expression."That tells us that these 21emotions are expressed in the same way by nearly everyone,"said DrAleix Martinez to The Daily Telegraph.For example,to express surprise,92percent of volunteers widened (睜大) their eyes and opened their mouth.And 99percent raised their cheeks (臉頰) and smiled to show being happy.
We are not always aware of our facial expressions,which can hold clues to how we really feel.So these results may have a big impact (影響) on medical treatment.If doctors were able to recognize more complex (復雜的) emotions,it would help doctors treat patients suffering from certain diseases.

分析 【文章主旨】這是一篇有關(guān)對人臉部表情研究的科學類文章,短文先介紹了人有六種基本的表情能告訴別人我們的感受,從而引出了科學家對面部表情的研究,短文還引用了新的研究(我們的臉可以做比我們想的更多的表情)以及科學家用電腦數(shù)據(jù)研究照片的相似性來說明面部表情的影響.
解答 46 D 細節(jié)理解題.根據(jù)文中第一段中Scientists used to believe we had six basic facial expressions that tell others how we feel 科學家認為我們只有六種基本的表情能告訴別人我們的感受.故選D.
47 C 細節(jié)理解題.根據(jù)文中第二段中Scientists from Ohio State University found out that humans can actually make 21different facial expressions after studying how people move their facial muscles.來自俄亥俄州立大學的科學家在研究人們?nèi)绾我苿用娌考∪夂蟀l(fā)現(xiàn)人類可以做出21種不同面部表情.可知來自俄亥俄州立大學的科學家發(fā)現(xiàn)人類可以做出21種不同面部表情是通過研究人們?nèi)绾我苿用娌考∪夂蟮模蔬xC.
48 C 推理分析題.根據(jù)題意找到This所在段,再根據(jù)語境語義聯(lián)系到The scientists then studied similarities…This helped them to define a facial expression.可知科學家研究了用電腦數(shù)據(jù)表達出的這些照片的相似性.這幫助他們定義面部表情.可知This指的是前文中的內(nèi)容,故選C.
49 D 推理判斷題.縱觀全文,可知這是一篇有關(guān)對人臉部表情研究的科學類文章,其中引用了新的研究(我們的臉可以做比我們想的更多的表情)以及科學家用電腦數(shù)據(jù)研究照片的相似性.所以我們可以得出這篇短文來自科學雜志,故選D.
點評 首先要仔細閱讀文章,掌握大意,然后結(jié)合具體的題目再讀短文,從中找出相關(guān)的信息,就可以確定正確答案.
