We have known for a long time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at particular times. It is not as simple as we might think, as new experiments have shown. In one experiment, flowers were kept in darkness. We might expect that the flowers, without any information about the time of the day, did not open as they usually do. In fact, they continued to open at their usual time. This shows that they have some mysterious (神秘的) way of knowing the time.
Their sense of time does not depend on information from the outside world; it is, so to speak, inside them, a kind of “inner clock”. This discovery may not seem to be very important. However, it was later found that not just plants but also animals including man have this “inner clock”which controls working of their bodies and their activities.
Human beings, then, are also controlled by this mysterious power. Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food. And our ability to concentrate(集中).One experiment was done for finding out .

If someone says to you, “give me five”, don't give five yuan to him! It will make others laugh! The person isn't asking for your money, but your fingers.
In the U.S.A, “give me five” or “give me the high five” is a good gesture(手势). You can see it often in films or on TV. It means the slapping (拍打)of each other's right hands together. People do it when something happy happens. For example, if a student does well in exams or gets No. 1 in his school sports meet, he will give high fives to his friends to celebrate.
Who did this gesture first? Why did he do that? It may come from the old Roman (古罗马的) gesture of raising（举起）the right arm for the emperor(皇帝). This showed that the person raising his arm had nothing in his hand and he couldn't hurt the emperor.

As I left his office, I felt so frustrated(沮丧). “How can I become a sports announcer if I can’t get a job in a radio station?” I asked aloud.
While I was waiting for the lift, I heard someone calling. It was MacArthur. “What was that you said about sports? Do you know anything about football?” Then he asked me to have a try. He was pleased with my performance, and he offered me a chance to work there.
