Article: Today, we know that the role of vitamins and minerals goes way beyond the prevention of deficiency diseases to actually preventing cancer and heart disease, the most fearsome killers of our time. With this knowledge has come the widespread call for nutritional supplementation -- and a confusing group of vitamin, mineral, and supplements lining the supermarket shelves. Far from contributing to better health, however, nutritional supplements threaten to turn a scientific breakthrough into a nutritional disaster. _ of vitamins and minerals -- especially vitamins A, C, and E-- would have consumers believe that the little vitamin pill in the bottle is all they need for good health. Take your vitamins in the morning, and you're covered. It's okay to eat fast foods for the rest of the day or skip meals to achieve today's fashionably skinny look. But vitamins and minerals are only one part of the nutritional puzzle. A diet rich in fiber and balanced in carbohydrates and protein is essential for good health. You can't get these things from a nutritional supplement. The focus on vitamin and mineral supplements may actually be robbing us of the full nutrition we seek. And no supplement can compare to the quality of nutrition found in natural sources. For example, our bodies turn carotenes from plant foods into vitamin A. Many supplements contain a single carotene, but natural sources are rich in many different carotenes. Many supplements contain a form of vitamin E that is made from chemicals, when natural vitamin E is more readily absorbed and used by the body. And science is still discovering the wealth of nutrients in foods. You'd be hard-pressed to find a supplement as nutritionally comprehensive and powerful as a balanced diet. Even if you could, you'd pay much more than if you got the same nutritional value from natural sources. But perhaps the greatest danger presented by nutritional supplements comes from the very real risks presented by self-medication. Anyone can walk into the market and buy as many... Question: What has given rise to the great need for nutritional supplements? Yes or no, is the answer "The information about the role of vitamins and minerals in health."?
No

Article: In 1966,Allen and Beatrice Garden, two professors at the University of Nevada in Reno, had a bright idea.They were interested in the evolution of language and the language abilities of great apes . Previous attempts to teach chimpanzees to talk had ended in failure and the matter was considered by most people to be closed. But the Gardens realized that speech and the language are not the same thing. Many deaf people, for example, are unable to speak but are perfectly able to communicate by gestures that have all the features of spoken language. The Garders suspected that previous experiments had failed because chimpanzees are physically unable to speak. They therefore decided to try teaching a chimpanzee to sign in the way that deaf people do. And their chosen _ , a female chimpanzee named Washoe after the country in which the university is, proved to be a skillful pupil. Though there is still debate about whether what Washoe learned was really equal to human language, there is no doubt that she learned a lot of words. All of this, however, raises a second question. If Washoe can learn a complex vocabulary of gestures from people, do they have such vocabularies naturally ? To examine that possibility, Amy Pollick and Frans de Waal of Emory University have looked at gestures and expressions in chimpanzees, Signaling by facial and oral expressions is common among primates . Signaling by gestures is limited to great apes. The researchers supposed that the meaning of expressions has been fixed by evolution while the meaning of gestures is learnt. If that were true, particular sorts of facial and oral expressions would occur only in particular circumstances, and this would be the same across groups and even species. The same gestures, on the contrary, would be used in different circumstances. The researchers found exactly what they expected. Expressions almost always occurred in the same circumstances in different groups and different species. Gestures seemed to have completely different meanings.... Question: What does the research carried out by Amy Pollick and Frans de Waal probably indicate ? Yes or no, is the answer "Human speech may develop from gestures"?
No

Q: Article: If parents bring up child with the aim of turning the child into a genius , they will cause great damage to him. According to several leading educational psychologists , this is one of the biggest mistakes which some parents make. Generally, the child will understand very well what the parent expects, and will fail. Unrealistic parental expectations can cause great damage to children. However, if parents are not unrealistic about what they expect their children to do, but are hopeful in a sensible way, the child may succeed in doing very well -- especially if the parents are very supportive (,) of their child. Michael Li is very lucky. He is very fond of music, and his parents help him a lot by taking him to concerts and arranging private piano and violin lessons for him. They even drive him 50 kilometres twice a week for violin lessons. Although Michael's mother knows very little about music, Michael's father plays the trumpet in a large orchestra . However, he never makes Michael enter music competitions if he is unwilling. Michael's friend, Winston Chen, however, is not so lucky. Although both his parents are successful musicians, they set too high a standard for Winston. They want their son to be as successful as they are and so they enter him in every piano competition held. They are very unhappy when he does not win. "When I was your age, I used to win every competition I entered." Winston's father tells him. Winston is always afraid that he will disappoint his parents and now he always seems quiet and unhappy. Question: The main idea of the passage is _ . Yes or no, is the answer "what differences there are between two kinds of parents"?
A: No

Article: Tattoos and body piercings have moved up on the trend list in recent years. Around Western schools lots of teens are sporting new holes and "flesh ink" . As with all other subjects, the Chinese will surely have to deal with this situation with respect to their children. To get a better view of what has happened in the West, 1et's sit down and hear what they say. Tiara from Indiana: I personally think body piercing is sickening. If there were supposed to be holes in your body,you would have been born with them. I do,however,think that ear piercing is not wrong. There is a difference between ear piercing and belly button piercing. Ear piercing is not nearly as dangerous. I would be sick if someone stuck a needle in my belly button. Lee from Illinois: Hi! I live in Illinois. I am 23. I have 12 tattoos and three piercings. I love my tattoos and consider myself an art collector. You would be surprised at who has given me the thumbs up on my art work. People on the street stop me to look at the tattoo on my leg. Most of them don't know what it is. They just think the work itself is great. Subotai from California: I'm not forbidden of self-expression,but when I see high school students getting these piercings, I really wonder. In some cases, the drive is deeper and darker than mere fashion. A friend of mine tried piercing her own tongue with a safety pin. It got infected and she had a tongue the size of a cow's. Jackson from Ohio: I don't think it is wrong, but when people do it all over the place like their face and everything--I think that's ridiculous. People who get the big "dragons that cover the whole body--I don't think that's necessary." When I see naked chicks on guys, I think, "You have no respect for women." Question: Who doesn't think tattoos and piercings except ear piercing are beautiful? Yes or no, is the answer "Tiara"?
No
