That is to say we must treasure every minute now. If we want to have a bright future, we should know how important time is and use it well.There is an old English saying: “Gain time, gain life.” 37 Time is something that we cant see or touch, but we can feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeably. We always say “Time is money”, but time is even more precious(珍贵的)than money, because when money is spent , we can earn it back. 38 So, some of us even say time is priceless(无价的).We should always remember: future is now. For us students, we should try our best to work hard in order to create a great future of our own. 39 We should do everything before us as soon as possible. And never put off what can be done today till tomorrow.As we all know , “Time and tide wait for no man.” 40 So from now on, work hard. Tomorrow will be better, and your future will be brighter. Remember: “No pains, no gains.” Todays hard work is the cause of tomorrows harvest.根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使短文意思通顺、内容完整，并将其标号填写在下面题号后的横线上。A. But if time is gone away, it will never return.B.
