Why do Americans struggle with watching their weight, while the French, who consume rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers conclude that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over. According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers' markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal. After a visit to the United States, Mireille Guiliano, author of French Women Don't Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym. In spite of all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity - or extreme overweight - among adults is only 6%. However, as American fast food gains acceptance and the young reject older traditions, the obesity rate among French children has reached 17% - and is growing. This text is mainly about the relationship between _ . A) children and adults B) Americans and the French C) life style and obesity D) fast food and overweight

Linking the Red Sea to the Indian Ocean, the blue waters of the Gulf of Aden near Somalia are one of the most important trading routes in the world. But they are also the most feared. Pirates whose targets are ships and their crew often show up there. On September 25, a Ukrainian ship carrying 30 tanks became another victim. The pirates have reportedly killed one of the crewmen and are now surrounded by the US Navy. But they are still demanding $ 20 million for the release of the ship. This year alone, more than 50 ships have been attacked, 25 hijacked , and 14 are currently being held. Of course this is nothing new either. Ever since there has been water and ships there have been pirates. The earliest documented history of pirates dates back to the 13th century in the Mediterranean Sea. Even the famous Roman emperor Julius Caesar was kidnapped by pirates at one time. Piracy reached its peak in the early l700s, especially in the Caribbean and off the coast of Africa. In the mid-20th-century, most pirates we're common thieves. They used hooks to steal on board commercial ships, and took all that they could find. These pirates were more likely to flee than fight if met by the crew. However, nowadays piracy has become a multi-million dollar business attracting many in poor countries such as Somalia. "The pirates are well funded and have all the latest equipment, including satellite phones," said a top UN representative in Somalia. In Asia, however, a trend started where pirates didn't just want to kidnap the stuff, they also wanted to control the ship. They would kill the crewmembers or kidnap them for ransom . After the recent kidnapping of Ukrainian ship, people are also worrying that tanks and arms on board would fall into hands of terrorists. Last week the UN called a meeting from all affected countries to fight piracy. "The international community is determined to stop these pirates who are weakening efforts to bring peace to Somalia. This cannot and will not... Unlike before, piracy nowadays _ . A) has spread to all corners of the world B) is more like terrorism and disturbs regional peace C) has become a key business for some poor countries D) has become the UN's top concern
