Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

     Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don't judge.

     A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

　　Have you 1 asked yourself why children go to school? You will probably say they go to learn their 2 language and other languages, arithmetic(算术), geography, history, science and all the other 3 . That's quite true; but 4 do they learn these things? And are these things all 5 they learn at school?

　　We send our children to go to school to 6 them for the time 7 they will be big and will begin to work for 8 . Nearly everything they study at school has some 9 use in their life. But is that the 10 reason why they go to school?

　　There's more in education(教育)than just 11 facts. We go to school 12 all to learn how to learn, so that when we have left school we can 13 to learn. A man who really knows how to learn will always be 64, because whenever he has to do something new which he has never had to do 15 he will rapidly teach himself how to do it 16 the best way. The uneducated(未受教育的)person, on the 17 hand, is 18 unable to do something new, or 19 it badly. The purpose(目的)of schools, therefore(因此), is not just to teach languages, arithmetic, geography, etc, 20 to teach pupil the way to learn.
