Article: At some time in your life you may have a strong desire to do something strange or terrible. However, chances are that you don't act on your impulse , but let it pass instead. You know that to take the action is wrong in some way and that other people will not accept your behavior. Perhaps the most interesting thing about the phenomenon of taboo behavior is how it can change over the years within the same society, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as On Death and Dying and Learning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject. One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is a topic that Americans talk about constantly. It's not taboo to talk about fat; it's taboo to be fat. The "in" look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their image as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline, and self-respect. In an image-conscious society like the U.S., thin is "in", fat is "out". It's not surprising, then, that millions of Americans have become obsessed with staying slim and "in shape". The pursuit of a youthful physical appearance is not, however, the only reason for America's fascination with diet and exercise. Recent research has shown the critical importance of diet and exercise for personal health. As in most technologically developed nations, the life-style of North Americans has changed dramatically during the course of the last century. Modern machines do all the... Question: In the U.S., thin is "in", fat is "out", this means _ . Yes or no, is the answer "thin is "fashionable", fat is "unfashionable""?
No

Article: In the United States, friendships can be close, constant, intense, generous, and real, yet fade away in a short time if things change. Neither side feels hurt by this. Both may exchange Christmas greeting for a year or two, perhaps a few letters for a while--then no more. If the same two people meet again by chance, even years later, they pick up the friendship where it's left off and are delighted. In the States, you can feel free to visit people's homes and share their holidays without fear that you are taking on a lasting obligation. Do not hesitate to accept hospitality because you cannot give it in return. No one will expect you to do so for they know you are far from home. Americans will enjoy welcoming you and be pleased if you accept their hospitality easily. Once you arrive there, the welcome will be full and warm and real. Most visitors find themselves easily invited into many homes there. In some countries it is considered inhospitable to entertain at home, offering what is felt as "merely" home cooked food, not "doing something" for your guest. It is felt that restaurant entertaining shows more respect and welcome. Or for various other reasons, such as crowded space, language difficulties, or family custom, outsiders are not invited into homes. In the United States, both methods are used, but it is often considered more friendly to invite a person to one's home than to go to a public place, except in pure business relationships. So, if your host or hostess brings you home, do not feel that you are being shown inferior treatment. Question: . Yes or no, is the answer "naughty children"?
(Answer)
Yes

Article: 66-year-old Dai once worked as a boat tracker along the Yangtze River. "It was something that required brute strength,but not that alone, "Dai said at his home in Xialong village, which sits at the entrance to Wuxia Gorge, one of the famous Three Gorges in Southwest China. "You needed a lot of skills to do what we did." When outboard motors became available in the 1980's,boat trackers became a thing of the past. Today, they are seen only occasionally along the river during festivals and cultural events. However, Dai can still remember a time when being pulled by tracker along the Yangtze was the only way for people to travel from village to village in the mountainous Wushan county. Due to the area's rich mining resources,his services were vital for companies that wanted to ship their goods. "I was 15 or 16 when I started", said the retiree,explaining that his father also worked as a tracker. "He died in 1964, when I was a teenager. I can't even remember us tracking together, but we did. It was so long ago." Dai said that boats crews worked in teams with a first, second and third master. The first master was the most essential because he sat in the boat and steered it along the safest route. "It was a key role. He had to guide the boat past jagged rocks and whirlpools," he said, adding that first masters were often the most experienced boatmen and the most familiar with the Yangtzer River. "My tracker days were dangerous," Dai said. "If the boat got caught in a whirlpool, it could have swallowed the boat and all the trackers down with it. The same thing would have happened if the halter broke." Dai's days as a tracker finally came to an end when his family invested in a motorboat in the early 1980s. He successfully applied for a license from Wushan shortly after. Question: What does the passage mainly tell about? Yes or no, is the answer "Dai's past life as a tracker."?
No
