练习材料：The great racing driver, Sir Malcolm Campbell, was the first man to drive at over 300 miles per hour. He set up a new world record in September 1935 at Bonneville Salt Flats, Utah. Bluebird, the car he was driving, had been specially built for him. It was over 30 feet in length and had a 2500 horse-power engine. Although Campbell reached a speed of over 304 miles per hour, he had great difficulty in controlling the car because a tyre burst during the first run. After his attempt, Campbell was disappointed to learn that his average speed had been 299 miles per hour. However, a few days later, he was told that a mistake had been made. His average speed had been 301 miles per hour. Since that time, racing drivers have reached speeds of over 400 miles an hour. Following in his father's footsteps many years later, Sir Malcolm's son, Donald, also set up a world record. Like his father, he was driving a car called Bluebird.

练习感悟：
最近发现自己一个问题，正常上班的时候，时间很规律，自己也能干很多事情，可是一到周末双休，自己就想着怎么样能休息一下，甚至是报复性的休息，就想什么都不做，好好放松一下。比如看一天的电视剧，或者打一会游戏。但是这些，都不太能在做完以后感到放松的满足。反而觉得自己的时间浪费了。还不如自己做做锻炼，出去走走，学学网课来的更开心。但是又觉得自己总保持这个状态，时间长了肯定会累。担心自己如果缺少必要放松，这个状态会不持久。
该学的时候认真学，该玩的时候放肆玩，不要做这个担心那个。这一点是我上学的时候就一直犯的毛病，直到现在还是会这样，只能说是历史遗留问题一直没有解决。
今天差点忘记学习了。
