　　As people continue to grow and age, our body systems(系统)continue to change．At a certain point in your life your body system will begin to weaken．Your strength may become weaker．It may become more difficult for you to see and hear．The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury．In order to live longer, we have always tried to slow or stop this change that leads us toward the end of our lives．

　　Many factors(因素)decide your health．A good diet plays an important role．The amount and type of exercise you get is another factor．Your living condition is yet another．But scientists studying aging problem want to know：Why do people grow old?They hope that by studying the aging medical science they may be able to make the length of life longer．

　　There is nothing to be afraid of as old age comes．Many consider the later part of life to be the best time for living．Physical activity may become less, but often you get better understanding of yourself and the world．

　　What we consider old age now may only be middle-aged some day soon．Who knows, with so many advances in medical science happening so quickly, life length may one day be measured in centuries, rather than in years!

完形填空

February 23．　　　　　　　　　　　　　　　　　　　　　　　　　　Sunday Sunny

　　Now that the Spring Festival is over, I only have school to look forward to．It’s 　　1　　 funny, I find myself looking forward more and more to schml．

　　As usual 　　2　　 can get little work 　　3　　 during the winter vacation．For one thing, the Spring Festival is always a big distraction(吸引心神而令人快乐之事)，and for days before and after 　　4　　 can get any work done．It’s all right if you really have a nice time, as I used to．But now I find myself 　　5　　 it less and less．I 　　6　　 enjoying fireworks and firecrackers years ago．The firecrackers especially get on my nerve．I really think we should stop making them, as everry year many children have their eys hurt or even 　　7　　．Even worse sometimes fires 　　8　　 out and whole buildings get 　　9　　 down．Still I suppose we’ll continue to make them as 　　10　　 as there is a market for them．

　　And the 　　11　　!People spend days buying．The result－too much and too rich which does nobody any good：chicken, duck, fish, meat and so on．What’s 　　12　　 they become 　　13　　 too．Too much of a good thing, as we say, and this visiting business too．It’s all right for a few really good friends to 　　14　　 together and chat over some tea or drinks．But mere acquaintance(熟人)and the usually not too neighbourly neighbours dropping 　　15　　 to say hello, but I find them a pain in the neck(讨厌的家伙)．Usually there is nothing to talk about 　　16　　 some meaningless words．

　　Oh yes, I did 　　17　　 myself skating on the nearby lake 　　18　　 a few times．The ice is not too good now and getting very 　　19　　．I stopped going before the Spring Festival．But there are people who are 　　20　　 too reckless(考虑后果的)or too ignorant or both, and we hear about people falling through thin ice every year．
