i know what i dont see; children jumping rope, playing or running in packs until they are summoned (召喚) home for family dinner. so, where have all the children gone?my educated guessthey are inside studying, completing extra tutoring sessions, participating in organized sports, watching television or glued to the latest ipad game. participation, a nation-wide event, is urging parents to rethink their views on outdoor play and motivate their children to become more physically active. research show children who receive greater parental support for physical activity are more likely to be active for at least 60 minutes per day. in a nation where 93% of our children are not active enough to meet the canadian physical activity guidelines and 26% are overweight, mother nature pleads:be a healthy role model. if you show your kids that you find enjoyment in being active, getting outside, and making physical activity a daily routine, they will be more likely to mirror these healthy actions. walking or cycling to work and going on nightly walks can show your kids the importance of maintaining good health and how engaging physical activity can be. limit screen time. video games, cell phones, television, and other tech-innovations are keeping children indoors. if youre inside all day, youre less likely to move around and more likely to gain weight. childhood obesity is on the rise and has no signs of slowing down. the results of the new studies indicate that childrens weight is influenced by whether they have a television in the bedroom. since spring has finally sprung, there is no better time than the present to encourage children to develop friendship with mother nature. lets tell our children what my parents always told me : go outside and play! 3. when the author was young, _a. he was encouraged to study hard b. he spent much time playing in nature c. he was taught the importance of curiosity d. his parents always warned him of the danger in nature 4. the underlined sentence in paragraph 2 suggests that the author_. a. doesnt think most 21st century parents will like his childhood b. can understand the thoughts of most 21st century parents c. thinks highly of his own childhood as a 21st century parent d. is not sure whether most 21st century parents will like him 5. who plays the most important role in making children active?a. their interests b. their teachers c. their parents d. participation cone of the most popular ways to demonstrate this years severe us winter appeared to be throuing out a glass of boiling water and watching it freeze instantly in mid-air. of course, the reason why the fun experiments impressed viewers is that nobody expects boiling water to turn to ice that quickly. contrary to our intuition (直覺)， hot water actually freezes faster than cold water! why? thats a mystery still waiting to be solved. as a matter of fact, this phenomenon has been observed for thousands of years, but it was brought to the worlds attention in 1963 by a tanzanian high school student, erasto mpemba. it all began when the young boy was learning to make ice cream in a cooking class. after putting sugar into boiling milk, the students were instructed to allow the mixture to cool down before putting it in the ice cream churner(攪拌機(jī)). too impatient to wait, mpenba put his ice cream mix in while it was still hot. to his and everyones surprise, his treat was the first to freeze! his explanation appeared so unbelievable that even his teacher thought mpemba must be mistaken. convinced that he was onto something, mpemba told a visiting physics professor about his accidental experiment. like his teacher, the professor was a little skeptical, but was willing to give the young boy the benefit of doubt and invited him to test the theory. the two began by filling samples of water of varying temperatures in glasses and placing them in a refrigerator. what they noticed was that it took longer for the water to freeze when the temperature was at 25 than when it was at much higher 90. since then, the phenomenon has been known as the mpemba effect. however, while the two were able to demonstrate it, neither could find a scientific explanation for why it occurred. over the years, researchers have come up with several theories. the theory that most believe is fairly straightforward. it is a known fact that hot water evaporates (蒸發(fā)) faster than cold water. hence, when boiling water is put into cold air, some of it turns into steam, leaving behind less to turn to ice. mpemba thought of this possibility and even tested it. unfortunately, he found no loss of volume in the ice formed between waters frozen at different temperatures. while other theories are plausible (似乎正確的) and can explain the phenomenon under certain conditions, none seems to provide a satisfactory universal solution to this strange physical property that has confounded scientists since aristotle observed i
