Have you ever tried to hide your emotions (情感)from someone during a conversation? {#blank#}1{#/blank#}

    Scientists from the Ohio State University have found that people are able to tell other people's emotions according to changes in the color of their faces.

    Scientists studied pictures of people's facial expressions. {#blank#}2{#/blank#} For example, happiness makes our faces red around the cheeks and a little blue around the chin. Disgust(厌恶)creates not only a blue-yellow color around the lips, but also a red- green color around the nose and forehead.

    “We believe these color patterns are the result of small changes in blood flow triggered(触发) by the central nervous(神经) system." Lead researcher Alex Martinez said.

    {#blank#}3{#/blank#} Does the color alone or also facial expressions help people tell other's emotions?

    To figure this out, scientists added color patterns to pictures of faces that showed no facial expressions. {#blank#}4{#/blank#}They were able to tell the emotions 75 percent of the timewithout any difficulty.{#blank#}5{#/blank#} For example, when two people are heatedly arguing over something, we say they are red in the face. When a person is very angry, we'd say he or she is blue in the face.

Daniel Olin was 11 years old when his parents moved to Canada. He liked his new school and made friends there，but then things at home started to change. His mum and dad began to argue and the arguments got worse and worse until one day，Daniel's mum left. With his father working long hours，to run away. And that's what he did. 

Very early one terribly cold morning when the snow was deep on the ground，he packed a bag with some clothes，some chocolate and a map of Canada and set off to a forest. He ran and ran until he could hardly breathe. His feet were heavy with the snow but he still walked on through deep snow, not even watching where he was going.

Then，disaster struck. A rock hidden by the deep snow caught his feet and Daniel fell to the ground. He had broken the bone. He was very cold and was starting to feel tired，but he knew that if he fell asleep in the snow, he would certainly die from the cold.

A tree shook ahead. From within the branches（树枝），a pair of yellow eyes watched Daniel. The puma had been following him. A puma is a large wild cat with claws that could tear（撕开） Daniel into pieces. But instead of moving in for the kill，arms and legs. Daniel was too frightened to move，but soon the warmth of the animal reached Daniel and he began to feel better. From time to time（口鼻） against Daniel and rocked his head gently. Clearly，the puma knew that Daniel must not fall asleep. This animal should have been a real danger to Daniel and yet the boy began to feel safe. 

They remained like that for several hours until Daniel and the puma heard voices. The rescue （援救） team had found them. 

Zhou Yan is a middle school student in Sichuan Province. She has got a new mobile phone (手机)! It's a gift from her parents. They want her to use it to learn English during the coming winter holiday. But Zhou uses it to watch videos (视频) and send messages (信息). She plays with her mobile phone all the time, even after going to bed! Her parents get very angry about that.

This morning, when she gets up, Zhou finds that she can't move her hands. Her parents take her to a doctor right away. After checking her carefully, the doctor says Zhou Yuan has got "mobile phone disease (疾病)". She'd better stop using her mobile phone right away, or she will have more problems (问题). Now Zhou uses her mobile phone for 30 minutes a day.

So, if you've just got a phone, watch out! Don't use it too much. Or you will get mobile phone disease. Remember if you find your arms and fingers start to hurt (疼), go to see a doctor right away. That's important.
