It’s true that almost everyone hopes for a better tomorrow such as a well-paid job and a happy family. To make this dream come true, what we are supposed to do is seize the present moment. In other words, we must take action right now for a bright future. Take Ma Yun for example. Shortly after quitting his job from a college, he started a small firm focusing on e-business for he longed to be a well-known businessman in the future. Despite the fact that he met with many difficulties at the very beginning, he didn’t give up but made up his mind to cherish every single day to realize his aspiration step by step. Finally, his hard work paid off----He has become a world-famous Internet tycoon. In a word, I hold the firm belief that if you do your best today your are bound to have a bright future. 试卷答案 1.；要使B刚要离开地面，则弹力应等于B的重力，即，故形变量，则，故A错误；A、缓慢提升物体A，物体A的动能不变，第一阶段与第二阶段弹簧的形变量相同，弹簧的弹性势能EP相同，由动能定理得：，， ，，由于在整个过程中，弹簧的弹性势能不变，物体A、B的动能不变，B的重力势能不变，由
