It's so simple and convenient that it couldn't possibly count (算作) as exercise, right? Wrong. Studies shows that regular walking can help you lose weight and reduce risk of heart disease.
If you don't believe us, then trust the research. In a study published in Diabetes Research in Clinical Practice, Japanese researchers tested fat men before and after they joined a one-year walking plan. All they did was up the number of steps they took during their daily activities, such as walking from the car to the grocery store（杂货店）. The result is: their blood pressure and cholesterol （胆固醇）levels improved and the amount of body fat around their abdomen（腹部） -- the dangerous kind of fat that leads to higher rates of heart disease and diabetes -- decreased.
That's good news, because walking has now become the most popular fitness activity in the United States. Convenient, simple, and gentle on the joints（关节）, walking is perhaps the easiest form of exercise to take. According to studies, four out of five women who start a walking program continue to walk, while half of women who attempt other types of exercise, such as swimming, drop out during the first few months. In addition, research has shown that walking regularly is better than running for your health and for losing weight.

新课标快乐提优暑假作业陕西旅游出版社系列答案
暑假衔接培优教材浙江工商大学出版社系列答案Take a look at the following list of numbers: 4, 8, 5, 3, 7, 9, 6. Read them loud. Now look away and spend 20 seconds memorizing them in order before saying them out loud again. If you speak English, you have about a 50% chance of remembering those perfectly. If you are Chinese, though, you’re almost certain to get it right every time. Why is that? Because we most easily memorize whatever we can say or read within a two-second period. And unlike English, the Chinese language allows them to fit all those seven numbers into two seconds.
That example comes from Stanislas Dahaene’s book The Number Sense. As Dahaene explains: Chinese number words are remarkably brief. Most of them can be spoken out in less than one-quarter of a second (for instance, 4 is “si” and 7 “qi”). Their English pronunciations are longer. The memory gap between English and Chinese apparently is entirely due to this difference in length.
It turns out that there is also a big difference in how number-naming systems in Western and Asian languages are constructed. In English, we say fourteen, sixteen, seventeen, eighteen and nineteen, so one might expect that we would also say oneteen, twoteen, threeteen, and fiveteen. But we don’t. We use a different form: eleven, twelve, thirteen and fifteen. For numbers above 20, we put the “decade” first and the unit number second (twenty-one, twenty-two), while for the teens, we do it the other way around (fourteen, seventeen, eighteen). The number system in English is highly irregular. Not so in China, Japan, and Korea. They have a logical counting system. Eleven is ten-one. Twelve is ten-two. Twenty-four is two-tens-four and so on.
That difference means that Asian children learn to count much faster than American children. Four-year-old Chinese children can count, on average, to 40. American children at that age can count only to 15. By the age of five, in other words, American children are already a year behind their Asian friends in the most fundamental of math skills.
The regularity of their number system also means that Asian children can perform basic functions, such as addition, far more easily. Ask an English-speaking seven-year-old to add thirty-seven plus twenty-two in her head, and she has to change the words to numbers (37+22). Only then can she do the math: 2 plus 7 is 9 and 30 and 20 is 50, which makes 59. Ask an Asian child to add three-tens-seven and two-tens-two, and then the necessary equation(等式) is right there, in the sentence. No number translation is necessary: it’s five-tens-nine.
When it comes to math, in other words, Asians have a built-in advantage. For years, students from China, South Korea, and Japan --- outperformed their Western classmates at mathematics, and the typical assumption is that it has something to do with a kind of Asian talent for math. The differences between the number systems in the East and the West suggest something very different --- that being good at math may also be rooted in a group’s culture.
