I first went to Harrow in the summer term. The school had the biggest swimming pool I had ever seen. It was a good joke to come up behind a naked boy, and push him into the pool. I made quite a habit of this with boys of my own size or less.
One day I saw a boy wrapped in a towel on the side of the pool. He was no bigger than I was, so I thought him a fair game. Coming secretly behind, I pushed him in, holding on to his towel so that it would not get wet, I was surprised to see an angry face come out from the water, and a being of great strength masking its way by face strokes (猛力地划)to the shore. I fled, but in vain. He overtook me, seized me violently, and threw me into the deepest part of the pool. I soon climbed out on the other side, and found myself surrounded by a crowd of younger boys.” Do you know what you have done?” they said, “It’s Amery; he is in Grade Six. He is champion at gym; he has got his football honor.”
I was frightened and felt ashamed. How could I tell his position when be was wrapped in a bath towel and so small.” He didn’t seem pleased at all, so I added in a most brilliant word,” My father, who is a great man, is also small.” At this be laughed, and after some general words about my rude behavior and how I had better be careful in the future, signified the incident was closed.

In earliest times, men considered lightning to be one of the great mysteries of nature. Some ancient people believed that lightning and thunder were the weapons of the gods.
In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs .
The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷针). This device protects buildings from being damaged by lightning.
Modern science has discovered that one stroke of lightning has a voltage (电压) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.
Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average of one person every day.
The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under tress. Also on,e should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.
