[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

D. enjoy what one has at the moment
