question:
Article: For a long time, the traditional method of identifying liars was to watch their body language, including facial expressions. What if the person appears to be nervous? Is the person unable to look me in the eye? Is he or she look around the room? What about other nervous movements, such as fidgeting or shifting from side to side? Many people--from parents to police officers and airport security personnel--depend on this method. But does a person's body and face reveal the truth? Not according to a new study. Talking, it seems, is the best way to smoke out a liar. That is what researchers in the United Kingdom found out recently. Their investigation took place at one place where lying can get you into big trouble--an airport. The researchers asked volunteers to pretend they were real passengers and then lie to airport security agents. Some of the agents used spoke conversation-based methods to question these make-believe passengers. Others depended instead on the person's body language, like lack of eye contact and showing signs of nervousness. The agents talking with the passengers were 20 times more likely to catch the liars. The study found that these conversation-based techniques can help you recognize when a person is lying to you. Like many methods, this conversation method has a name. It is called Controlled Cognitive Engagement or CCE, for short. The British government partly financed this study. The American Psychological (APA) published the findings. Body language cannot be trusted. Using body language and facial expressions to catch someone in a lie is really hard. And it only works, seemingly, by chance. Thomas Ormerod is the head of the School of Psychology at the University of Sussex in England. On the APA website, he reported that the "suspicious-signs method"--or using body language--"almost completely fails" in finding lies.
Answer: Communicate with researchers by talking.
answer:
What should volunteers in the investigation do?

question:
Article: I'm a Chinese student studying in Canada. I have been a boarder with the Carsons for more than a year and a half. The Carsons live in their own house, which has four bedrooms including the one in the basement which I live in. Judy does all the work in the house and Andrew is responsible for the work in the garden. When they go out in they evening, they often ask me to look after their children. Judy's parents, Mr. and Mrs. Morris, lived in another city. Judy was their only child and naturally they doted on Judy's children. They often sent the children presents. Last April Mr. Morris died. Now that Mrs. Morris was quite alone, I expected that Judy would want her to come and live with them. One day, Margaret, Judy's daughter, told me grandma was coming to live with them and her daddy and mummy would want my room back. The news didn't surprise me and the next day I went to Judy and asked her about it. I said I couldn't think of living in their basement room any longer if it was needed for Mrs. Morris. Judy seemed surprised at first. Then she told me there was no deed for me to move, for they hadn't yet come to any decision about her mother coming to live with them. "Naturally I'm worried about my mother. She has been in poor health." She smiled sadly and added. "To be honest, Andrew and my mother have never got on well. We'll wait a bit and see what happens. Perhaps Mohter will be all right living herself, or perhaps they will both change their minds." That was six months ago. During this time I've heard that Mrs. Morris has had two illnesses and that her health has got worse. A nursing home was mentioned once but Mrs. Morris refused to go there. So up to now she's still living alone and I'm still living in the basement room.
Answer: He is a student who pays to live and have meals at the Carsons' house.
answer:
What is the relationship between the speaker and the Carsons?

Article: To explain why he liked his art teacher the best, 16-year-old Dainzin Tanam could not write more words than a simple sentence "Because he teaches me painting." In the eyes of his teachers at the Lhasa Special Education School, the deaf boy was a little painter. Five years ago, however, all Tanam could do was to stay in bed until noon, and then stare at the sky through the window, waiting for his parents' return. His mother Yangzom said she had no other choice but to lock him in the house every day as she and her husband had to work and they did not want to allow the boy to roam the streets. "Every day when I came back home and saw my lonely poor son, I felt my heart hurt. But now I can finally feel a bit relieved," the mother said. She said it was the school that changed his son. "Without the school, I dared not imagine how my son would be now." With a governmental fund of 4.5 million yuan, the special education school was founded in 2000. The only government-run school for handicapped children in Tibet, it now has 28 teachers and 120 school children in nine classes of 5 grades. Eight classes in the school are for deaf kids and the other one is for blind kids. Students can enjoy free food, boarding, clothing and medical services in the school, which is open to deaf and blind children from all over the autonomous region. Tibetan sign language and Tibetan Braille are basic courses here. Children also have Tibetan, Chinese, mathematics, science, painting, dancing and sports lessons. A "black and white" textbook seemed appealing among the color1ful books in Tanam's schoolbag. The text was handwritten. It was the Tibetan language textbook compiled and written by teachers themselves. "As textbooks for students in ordinary schools sometimes are too abstract and hard for our kids to understand, two other Tibetan language teachers and I compiled the textbook to make things easier for them," said teacher Dawa. Those books with the love of all the teachers, though not spoke out, will surely help children enjoy their life by supporting themselves after leaving the school.
