Many theories concerning the causes of juvenile delinquency crimes committed by young people focus either on the individual or on society as the major contributing influence. Theories 16 on the individual suggest that children engage in criminal behavior 17 they were not sufficiently penalized for previous misdeeds or that they have learned criminal behavior through 18 with others. Theories focusing on the role of society suggest that children commit crimes in 19 to their failure to rise above their socioeconomic status 20 as a rejection of middleclass values. Most theories of juvenile delinquency have focused on children from disadvantaged families, 21 the fact that children from wealthy homes also commit crimes. The latter may commit crimes 22 lack of adequate parental control. All theories, however, are tentative and are 23 to criticism.

C I’ve recently turned fifty, which is young for a tree, midlife for an elephant, and ancient for a sportsman. Fifty is a nice number for the states in the US or for a national speed limit but it is not a number that I was prepared to have hung on me. Fifty is supposed to be my father’s age, but now I am stuck with this number and everything it means. A few days ago, a friend tried to cheer me up by saying, “Fifty is what forty used to be.”He had made an inspirational point: Am I over the hillPeople keep telling me that the hill has been moved, and I keep telling them that the highjump bar has dropped from the six feet I once easily cleared to the four feet that is impossible for me now. “Your are not getting older, you are getting better,” says Dr. Joyce Brothers. This, however, is the kind of doctor who inspires a second opinion. And so, as I approach the day when I can not even jump over the tennis net, I am moved to share some thoughts on aging with you. I am moved to show how aging feels to me physically and mentally. Getting older, of course, is obviously a better change than the one that brings you eulogies(颂词,悼词). In fact, a poet named Robert Browning considered it the best change of all: Grow old along with me! The best is yet to me. Whether or not Browning was right, most of my first fifty years have been golden ones, so I will settle for what is ahead being as good as what has gone by. I find myself moving toward what is ahead with a curious blend (混合) of both fighting and accepting my aging, hoping that the philosopher(哲学家) was right when he said, “Old is always fifteen years from now. ” When the author turned fifty, people around him.
