Is that person really glad to see me? Or is he just being polite? Some people struggle to tell an artificial smile from a truly happy-one. And computers have found this task even more difficult. Recently, researchers have trained a program to detect when a smile is genuine(真诚的).
Visual computing researchers at the University of Bradford in the U. K. started with a software for analyzing a changing facial expression. This program can examine a video clip of a human head and identify(确认) specific details around the eyes, cheeks and mouth. Then the program tracks the details relative to each other as the face smiles.
Next,the scientists had their program evaluate(评估)two sets of video clips. In one subjects performed posed smiles. In the other, they watched a film that inspired genuine displays of emotion. The program calculated the differences among the subjects’ faces during the two clips. And it turns out that one's mouth, cheeks and eyes move differently when pretending to smile.
In particular, the muscles around the eyes shift 10 percent more for a real smile than they do for a fake one. These results are in the journal Advanced Engineering Informatics. "A genuine smile is indeed in the eyes. The computer aids analysis of the exact weight distribution of human smiles across the face.” Hassan Ugail and Ahmad Al-dahoud say.
The researchers suggest their work could improve a computer's ability to analyze facial expressions and thus to interact more smoothly with humans. But their real accomplishment is in proving Tyra Banks right: "You have to smile with your eyes."
1.What's the purpose of the program?
A.To tell different smiles. B.To detect human heads.
C.To examine human faces. D.To record facial expressions.
2.What did the researchers do in the program?
A.They performed posed smiles. B.They analyzed different video clips.
C.They improved a computer's ability. D.They evaluated a very special software.
3.What result have the researchers found from the program?
A.Smiling with eyes is the most important.
B.Eyes reflect whether a smile is real or not.
C.Mouth,cheeks and eyes always move the same.
D.Muscles move more frequently when people do a faking smile,
4.In which section of a newspaper may this text appear?
A.Entertainment. B.Health.
C.Inventions. D.Science.

First aid means what it says the aid, or help that can be given to an injured person first which is before any other help. Usually the first thing we should do if a serious accident happens is to telephone for an ambulance, but sometimes quick actions by us may save someone's life.
Shock: people often suffer from shock after receiving an injury. The face turns grey and the skin becomes damp and cold. They breathe quickly. They should be kept warm. Cover them with a blanket and give them a warm drink.
Broken Bones: Don't move the person. Send for an ambulance at once.
Poison: A person who has swallowed poison should be taken to hospital at once. With some poisons, sleeping pills, for example, it is a good thing to make the person sick by pushing your fingers down his throat. But if he has swallowed some kind of acid, or anything that burns, it would be a bad thing to make the person sick by pushing your fingers down his throat. The poison would burn his throat as it came up. It is, therefore, best to find out what the person has taken so that you can call to tell the doctor.
Suffocation: This means not being able to breathe. For example, a drowning person will have his lungs full of water. Lay him down with his head lower than the rest of his body so that the water will drain out. If a person has something stuck in his throat, try to remove it with your fingers, or by hitting him on the back. When a person has stopped breathing because of drowning, electric shock, breathing in a poisonous gas etc. you can help him to begin breathing again.
Remember: When an accident happens, send someone to telephone for an ambulance at once. Keep the injured person warm and quiet. Give him plenty of air. Do not let other people crowd around him. If you see an injured person who is being looked after, keep away.
1.The underlined words "drain out" in Paragraph 5 probably mean __________.
A.leave out B.squeeze out
C.flow away D.let out
2.When someone is injured, what should we do first?
A.Keep him warm with a blanket.
B.Send for an ambulance at once.
C.Make him sick by pushing your fingers down his throat.
D.Lay him down with his head lower.
3.The passage is mainly about __________.
A.the importance of first aid B.the symptoms of shocks
C.the types of injuries D.how to offer first aid
4.Where would this article probably appear?
A.In a safety booklet . B.In an advertisement.
C.In a newspaper. D.In a popular magazine.

Just listen
I suspect that the most basic and powerful way to connect to another person is to listen. Just listen. Perhaps the most important thing we ever give each other is our36, and especially if it’s given from the37. When people are talking, there’s no need to do anything but38them. Just take them39. Listen to what they’re saying. Care about it. Most times caring about it is even more important than40it.
One of my patients told me that when she41to tell her story, people often42to tell her that they had once had something just like what happened to her. Subtly, her pain became a story about themselves. 43she stopped talking to most people. It was just too44. We connect through listening. When we interrupt what someone is saying to let them know that we understand, we move the45of attention to ourselves. But when we listen, they know we care.
I have ever learned to46to someone crying by just listening. In the old days I used to reach for the tissues(纸巾)47I realized that passing a person a tissue may be just another way to shut them48, to take them out of their49of sadness and pain. Now I just listen. When they have cried all they need to cry, they find me there50them.
This51thing has not been that easy to learn. It certainly went against everything I had been 52since I was very young at school. I thought people listened only because they were too53to speak or did not know the answer. A loving silence often has far more54to connect than the most well-intentioned(善意的)55.
