14．Science can't explain the power of pets，but many studies have shown that the company of pets can help lower lood pressure （血压） and raise chances of recovering from a heart attack，reduce loneliness and spread all-round good cheer．
Any owner will tell you how much joy a pet brings．For some，an animal provides more comfort than a husband/wife．A 2002study 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 5minutes 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 36fat people and their equally fat dogs on diet-and-exercise programs； a separate group of 56people without pets were put on a diet program．On average，people lost about I1pounds，or 5% of their body weight．Their dogs did even better，losing an average of 12pounds，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 t worth doing．

阅读理解
Umbrella is what we easily forget and leave behind in our daily life． When the weather is fine, we certainly don’t think of it; only when it's raining, we’ll carry it purposefully． But as soon as the rain stops, most likely we’ll forget 1. we’ve put it． It has to wait patiently and pitifully for2. owner to claim it, otherwise it’ll remain alone as a deserted umbrella．
Once I suddenly found my longtime 3. (use) umbrella “disappeared” I really got lost and regretted quite some time 4.my own carelessness．
Several days later, out of my 5. (expect), I saw it quietly stand in a corner of the house where I worked． I was extremely glad to regain it． Looking carefully at it, though it was so familiar 6. me, I found for the first time its wooden handle 7.（wear）out as a result of repeated rain-wash for years． I sought for it only when I needed it． It occurred to me that I should have paid 8.(much) attention to it．
It sets me thinking． Around us there are always people giving us support in silence just like9. umbrella that protects us from the rain or any wretched weather． Will gou think of those individuals 10. have helped you get through difficlty when you are leading a comfortable life?
