问题 单项选择题

阅读下面的短文,回答27~30题。

展露微笑会让人留下美好印象。但是你知道吗,惊恐的表情才最引人注目。美国科学家近日通过比较大脑处理各种面部表情的速度,得出结论认为,惊恐的表情能够最快地被人类意识到。相关论文发表在《情绪》(Emotion)上。

此次研究由美国范德比尔特大学的心理学家David Zald领导。他和研究小组利用视觉闪光抑制(visual flash suppression)技术(该敛术能够减慢大脑对面部表情的反应速度),和一个能让双眼同时观看不同图像的阅读器,向参与实验者的一只眼睛展示静态的面部表情图像,向另一只眼睛展示一串快速翻动的随机图像,并让参与者报告他们第一眼意识到静态面部表情的时间。

结果发现,相比较中性或快乐的表情,参与者意识到惊恐表情的速度要快得多。而且,Zald表示,这种现象在实验中具有很大的普遍性。

研究人员认为,惊恐是对人类很重要的信息,它会提醒人们注意潜在的危险。所以惊恐图像在视觉处理过程中走了“捷径”,更快地被人类所意识到。

同时,此次研究也显示了大脑对微笑的“漠不关心”。zald说:“快乐的表情被察觉速度甚至比中性表情还要慢。”这表明,对于没有什么危险的信号,大脑相应的关注也较少。

Zald表示,面部表情对于人们传递社会交往信息至关重要。有些人,比如孤独症儿童,无法正确地判断别人的情感表情,结果就会导致严重的社交困难。

对于第三画划线部分理解正确的一项是()。

A.我们在现实生活中,对于惊恐表情的反应比中性或快乐的表情速度更快

B.研究表明大多数人大脑都对于惊恐表情的加工处理更快速,跟我们的预测不符

C.研究结论表明了我们对于惊恐表情较中性或快乐的表情更为敏感

D.大脑对微笑“漠不关心”

答案

参考答案:C

解析:

选项A中“在现实生活中”错误,选项B、D在文中第三段没有提及,故答案选C。

My mom is a teacher.She finds a lesson in everything.I was watching Sesame Street by my second birthday so I’d   16   my ABCs and 123s.Our weekly family trips to the library began when I was three.And my mom had me spotting (认出) the historical markers with childlike   17   on family vacations by the time I was six.For her, life was all about learning.But the biggest lesson she   18   me was never to let my   19   define who I am, and never forget what is   20   in life.
I was born with Freeman-Sheldon Syndrome, an extremely   21   genetic bone and muscular disorder.There are only about 100 reported   22 .At birth, my knees were bent more than 90 degrees, and I had my first surgery to   23   them when I was just six weeks old.This surgery was the first of many in my   24 .I’d had 26 surgeries by the time I was 15.
Strange as it   25  , I have good memories of my medical days.One of my   26   is about my mom and me being in the hospital cafeteria(自助餐厅).We sat down for an ice cream sandwich dessert.It was   27   fancy, but at that moment, I knew I was   28 .
My parents pushed me to be as   29   as possible — even when I didn’t want to be.My mom taught me that I could do anything and that I should   30   let my disability stop me.In high school, I was a member of the National Honor Society, and in college, I was editor-in-chief of my school newspaper.I wouldn’t have had the   31   to push myself if my parents hadn’t been there,   32   me on and giving me a reality check when I got down on myself.
Every night before I go to bed, I   33   my mom for everything, for all the great help she’s given me.And   34   I get older, I know that “Thanks, Mom” is about so much more than the physical assistance.And that’s   35   matters the most.
