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 (恶心的).
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 (气味)",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 (睁大) their eyes and opened their mouth.And 99percent raised their cheeks (脸颊) 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 (影响) on medical treatment.If doctors were able to recognize more complex (复杂的) emotions,it would help doctors treat patients suffering from certain diseases.

分析 【文章主旨】这是一篇有关对人脸部表情研究的科学类文章,短文先介绍了人有六种基本的表情能告诉别人我们的感受,从而引出了科学家对面部表情的研究,短文还引用了新的研究(我们的脸可以做比我们想的更多的表情)以及科学家用电脑数据研究照片的相似性来说明面部表情的影响.
解答 46 D 细节理解题.根据文中第一段中Scientists used to believe we had six basic facial expressions that tell others how we feel 科学家认为我们只有六种基本的表情能告诉别人我们的感受.故选D.
47 C 细节理解题.根据文中第二段中Scientists from Ohio State University found out that humans can actually make 21different facial expressions after studying how people move their facial muscles.来自俄亥俄州立大学的科学家在研究人们如何移动面部肌肉后发现人类可以做出21种不同面部表情.可知来自俄亥俄州立大学的科学家发现人类可以做出21种不同面部表情是通过研究人们如何移动面部肌肉后的,故选C.
48 C 推理分析题.根据题意找到This所在段,再根据语境语义联系到The scientists then studied similarities…This helped them to define a facial expression.可知科学家研究了用电脑数据表达出的这些照片的相似性.这帮助他们定义面部表情.可知This指的是前文中的内容,故选C.
49 D 推理判断题.纵观全文,可知这是一篇有关对人脸部表情研究的科学类文章,其中引用了新的研究(我们的脸可以做比我们想的更多的表情)以及科学家用电脑数据研究照片的相似性.所以我们可以得出这篇短文来自科学杂志,故选D.
点评 首先要仔细阅读文章,掌握大意,然后结合具体的题目再读短文,从中找出相关的信息,就可以确定正确答案.
