[单项选择]

When we think about happiness, we usually think of something extraordinary, a peak of great delight--and those peaks seem to get rarer the older we get.
For a child, happiness has a magical quality. I remember making hide-outs in newly cut hay, playing cops and robbers in the woods, getting a speaking part in the school play. Of course, kids also experience lows, but their delight at such peaks of pleasure as winning a race or getting a new bike is unreserved.
For teenagers, or people under twenty, the concept of happiness changes. Suddenly it’ s conditional on such things as excitement, love, and popularity. I can still feel the agony of not being invited to a party that almost everyone else was going to. But I also recall the great happiness of being invited at another event to dance with a very handsome young man.
In adulthood the things that bring great joy--birth, love, marriage--also bring responsibility and the risk of loss. Love may not last,
A. think of something extraordinary
B. experience delight at an old age
C. feel the magic quality of pleasure
D. enjoy what one has at the moment
