Q: Article: People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals each day. Low-calorie Diets Do Not Work The reason people cannot lose weight by starving themselves is that their metabolism will detect any major drop in calories and it will then adjust itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2, 500 calories per day and not gain any weight. Low-fat Diets Do Not Work Many people in today's society are buying mostly low- fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle. Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight.

Q: Article: Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf's howl and it appears that there may be more to discover. One theory is that wolves howl to bend better together. It's almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior. Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be "punished" for Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ----Why do welves howl for sure? What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering. Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow. This is often seen to occat in the morning, as if wolves were doing some sotr of "roll rall"where wolves all howl togeter to howl, very likely others will follow.

Q: Article: Who won China's first gold medal at the 2014 Sochi Winter Olympics? It was Li Jianrou. The 27-year-old finished first in the women's 500m short track speed skating on Feb 13. The race was full of drama. Three athletes fell over because of an accident caused by Elise Christie of Britain in the second turn and Li became the surprise winner. Three-time defending champion Wang Meng of China missed the Olympics after breaking her ankle last month. Li had little experience in the race, where getting off to a quick Start is important. But she kept her cool while everyone else was falling around her. "I feel very lucky," Li said through a translator. She and one of her coaches cried tears of joy after China joined South Korea as the only countries to win the same short track event four Olympics in a row. The Koreans won the 3,000 relay in 1994, 1998, 2002 and 2006. "I cried because I was so excited," Li said. "My coach told me this medal is for Wang Meng as well, so I felt very moved." Li's victory made up for the surprising fall of teammate Fan Kexin in the semifinals. In the semis, Fan didn't even complete the first lap of the race, catching her left blade as she skated near the front. She crashed on all fours into the crew of workers who maintain the ice between races. They climbed onto the top of the pads to avoid being injured by Fan's long, sharp blades. Arianna Fontana of Italy took the silver and Park Seung-hi of South Korea earned the bronze.
