4. “Time,” says the proverb, “is money”. This means that every moment well spent may put some money into our pockets. If our time is usefully employed, it will either turn out some useful important piece of work which will fetch its price in the market, or1. it will add to our experience increase our capacities so as to enable us to earn money when the proper opportunity comes. Our life is nothing more than our time. To kill time is therefore a form of suicide. 2.We are shocked when we think of death, we spare no pains, no trouble, no expense to preserve life. 3.But we are too often indifferent to the loss of an hour or of a day, forgetting that our life is the sum total of the days of the hours we live. Our life is a brief period measuring some seventy or eighty years in all. But nearly one third of this has to be spent in sleep; some years have to be spent over our meals; some in making journeys on lvoyages by sea; some in merry making. Now if all these years were to be deducted(扣除) from the term over which our life extends, we shall find about twenty or thirty years at our disposal for active work. 4.Whoever remembers this can never willingly waste a single moment of his life. All time is precious，but the time of our childhood of our youth is more precious than any other portion of our existence.5.for those are the periods when we can acquire knowledge develop our capacities. If we allow these morning hours of life to slip away, we shall never be able to recover the loss. Just as money laid out at interests doubles trebles itself in time, so the precious hours of childhood youth, if properly used, will yield us incalculable advantages.(20分)
