In Your Face

Why is this man so angry? Wedon't know the reason, but we can see the emotion in his face.Whatever cultureyou have, you can understand the feeling that he is expressing.

Forty years ago, psychologistPaul Ekman of the University of California, San Francisco, became inter-ested in how people's faceshow their feelings. He took photographs of Americans expressing variousemo-tions. Then he showed them to the Fore people, who live in the jungle inNew Guinea.Most of the Fore had never seen foreign faces, but they easily understoodAmerican's expressions of anger, happiness, sadness,disgust, fear, andsurprise.

Then Ekman did the sameexperiment in reverse. He showed pictures of Fore faces to Americans,and theresults were similar. Americans had no problems reading the emotions on theFore people's faces. Ekman's research gave powerful support to the theory thatfacial expressions for basic emotions are the same everywhere. He did moreresearch inJapan,Brazil, andArgentina, and got the samere-sults.

According to Ekman, these sixemotions are universal because they are built into our brains. They developedto help us deal with things quickly that might hurt us. Some emotional triggersare universal as well. When something suddenly comes into sight, people feelfear, because it might be dangerous.But most emotional triggers are learned.For example, two people might smell newly cut grass. One reason spent wonderfulsummers in the country as a child, so the smell makes him happy. The otherperson remembers working very hard on a farm and being hungry, so he feels sad.

Once we make an emotionalassociation in our brain, it is difficult, and sometimes impossible, to changeit. "Emotion is the least changeable part of the brain. " says Ekman.But we can learn to manage our emotions better. For instance, we can be moreaware of things that make us angry, and we can think before we react.

There are many differencesbetween cultures, in their languages and customs. But a smile is exact-ly thesame everywhere.

Paul Ekman studies people's faces in different cultures.

A.Right

B.Wrong

C.Not mentioned

第6题
When I was young, bedtime was always my favourite part of the day. Wearing soft pajamas and with Tom, my stuffed monkey, in my arms, I left no pressure at all.

I named Tom after my uncle when I compared Tom's long arms and legs to his. One night I ran up to Uncle Tom at a family party and told him I had named my monkey after him. His eyebrows wrinkled in confusion, then a chuckle(咯咯笑)escaped his lips. I guessed he didn't understand how important it was to me.

Even if Uncle Tom didn't think my monkey was special, I certainly did. I dressed him in a white baby nightgown. My mother thought that Tom was the best-dressed stuffed animal in the world. Yes, he was certainly a fashionable creature. The strong cologne(科隆香水)I used on him years ago made him still smell" pretty".

For a long time, Tom went everywhere with me. He was my best friend, and I told him everything. But when I turned twelve, I realized I was too old for stuffed animals. I thought people would think I was babyish, so I put him in the cupboard with the rest of my teddy bears and dolls. I begged him to understand why I was doing this, but at the same time I longed to talk to him again.

It took me several years to realize that it was Ok to miss Tom. I know now that maturity (成熟)doesn't only mean growing up and taking on more responsibility. It also means holding on to your childhood and acting young sometimes.

Which of the following is NOT true according to the text?

A.Bedtime used to be the writer's favourite part of the day because of the stuffed monkey.

B.Uncle Tom liked the stuffed monkey as much as the writer.

C.The writer used to carry the monkey with her wherever she went.

D.Years later the writer realized that it was not wrong to miss Monkey Tom.
