II) Sample for Translation What is time? Is it a dimension like height and width? Or is it a flow like a river? Time is too difficult to think about. To the man in the street, whatever it is, time is precious, as life is short. So many people say time is money. Time cannot be reversed and no one can turn back the clock. Lost time is never to be found. As we can see, no one stands still. If you are not moving ahead, you are falling behind. If you want to succeed, time management is the No. 1 problem. That’s why some people say, “We are slaves to nothing but the clock.” Time is today, not tomorrow or next week. If you want every minute to count, you must be masters of time.
Dictation We can perhaps say that there is nothing in the world that has affected human life as deeply as time, or has evoked our emotions as strongly as time. Just think how many people have wondered about the change of the seasons, the change of day and night, and the change of our life. People are constantly thinking of the past, the present and future because the past brings happy memories, regrets, experiences and Wisdom; the present brings needs, worries, power and purpose; and the future brings promises, expectations and anxieties. But what Is time? What is this “thing” that we can not see or touch? We used to think that time is what the calendar and clock tell us. But now the greatest scientists have told us that time does not exist except in our imagination. It is a mere human invention.
