跪求以珍惜时间为主题的英文演讲稿，急~！

As a popular saying goes, "Time is money. "In fact, time is more precious than money. When money is spent, you can earn it back if you want to. However, when time is gone, it will never come back.As the pace of modern life continues to accelerate ,the time at our disposal is quite limited. But there are a lot of things to be done in our lives. We should make full use of our time to fulfil what is useful to us. For instance, as students we should devote most of our time to our academic studies. In this way we can acquire new knowledge and skill necessary for our future carrier.In my opinion, wasting time means wasting our valuable life. But many of us don't realize this .They think time is inexhaustable. I'm not in favor of such of a view .Hence ,my conclusion is that we should never put off what can be today until tomorrow.

Since I entered college I have felt a great burden off my mind and I just want to relax. So do my classmates. We enjoy playing cards and are very skillful at it. We seldom work on our lessons unless there is an examination. Then we work under pressure. I know it is not good， but what I lack is self control. Mat of us know it is a problem， and it is time we did something about it.
As youth， we are in the prime of our life. We should make good use of our golden time. The teachers take pains to teach us every day so that we can acquire more knowledge. We should not fail their expectations. I should not rest content with what I have done. Entering cnllege is just a step in the threshold of the palace of knowledge. The road is long. The modern age needs the well educated. The future world is highly competitive. If we idle away our time while young wo shall regret it in vain when we are did.
From now on I will concentrate all my energy on my studies as to qualify myself as a talent in the 21st century. Time and tide wait for no man. I should value my time. What about you， my friend？
