请阅读下面短文,并按要求以Our Life Rests on Our Choice为题,用英语写一篇150词左右的文章。

    Life is a matter of choice. Seemingly, it means a choice of concrete (具体的) things. But in fact, it means choosing a way of life. Life is to be lived and enjoyed, not to be wasted or complained about.

    Hardly can we forget the time when our society faced the threat from the life-and death disease --- SARS. Yet, even during those dreadful times, some suffering people remained optimistic. Instead of wearing white masks, some people turned to color1 ful ones, and thus displayed a happy mood. And some creative people dubbed SARS to mean “SMILE AND REMAIN SMILING.” People who survive these kinds of circumstances decide in their minds to carry on in spite of the hardships.

    Although we cannot choose our appearance, inborn gifts and even avoid unexpected disasters and adversities (逆境), we do have the right to choose to live optimistically, to love our lives, to have dreams, and to cherish hopes.

    Every morning when we get up, we have a choice of how we want to approach life that day.
