【正确答案】It is most startling to hear a watch or clock clicking away the seconds, each click indicating the shortening of one’s life by a little bit. Likewise, with each page torn off the wall calendar, one’s life is shortened by another day. Time, therefore, is life. Nevertheless, few people treasure their time as much as their life. Time must not be wasted if you want to do your bit in your remaining years or acquire some useful knowledge to improve yourself and help others, so that your life may turn out to be significant and fruitful. All that is foolproof, yet few people really strive to make the best use of their time.
