In the last few years, some researchers have decided to study why kids lie(撒谎)，So they made up a special team of 12 students, all under the age of 21.
Each student was given 36 cards, and each card listed a topic that teens sometimes lie about to their parents, The researchers worked through the cards with the teens, learning what things the kid was lying to his parents about, and why.
By the end of the interviews, the kids saw for the first time how much they were lying and how many of family’s rules they had broken. It was reported that 98% of the teens had lied to their parents.
Out of the 36 topics, the average(平均) teen was lying to his parents about 12 of them. The teens lied about what movie they went to, and whom they went with .They lied about how they spent their afternoons while their parents were at work, and something like that.
Most parents hear their child lie and think he’s too young to understand what lies are or that lying is wrong. They believe their child will stop when he gets older. Many books also advise parents to just let lies go — they’ll grow out of it. But the truth is that kids grow into it. In studies where children are observed(观察) in their natural environment, a 4-year-old child will lie once every two hours, while a 6-year-old child will lie about once every hour and a half.

In the United States, 30 percent of the adult (成年人) population has a “weight problem”. To many people, the case is clear: we eat too much. But scientific evidence（证据）does little to support the idea. Going back to the America of 1910, we find that people were thinner than today. Yet they ate more food. In those days, people worked harder physically, walked more, used machines much less, and didn’t watch TV.

   Several modern studies, moreover, have shown that fat people do not eat more on average (平均) than thinner people. In fact, some investigations (调查), such as a 1990 study of 3,545 London office workers, show that fatter people eat less than slimmer people.

   Studies show that slim people are more active than fat people. A study by a research group of Stanford University School of Medicine found the following interesting facts:

  The more the men ran, the more fat they lost.

  The more they ran, the more they ate.

  Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

The two largest islands of the British Isles are Great Britain and Ireland. England, Wales and Scotland together form Great Britain. Scotland, lying in the northern part of Great Britain and bordering(接壤)England on the south, is half the size of England and Wales, having an area of about 76 000 square kilometers. Most of Northern Scotland is mountainous area known as the Scottish Highlands. In the center of Scotland there are the Central Low-lands, and the south is waving, hilly area known as the Southern Uplands which rise to 800m. There are many rivers in Great Britain, but they are not very long. The rivers which run to the east are longer than the ones which run to the west.

In Scotland the main rainy winds come from the Atlantic Ocean. The west part is wet with an average(平均) rainfall of up to 200cm while the east is dry with about 75cm. The winters are cold with an average January temperature of 4℃. The summers are cold and warm but rarely hot.
