Wind is the great maker of waves. There are exceptions (例外), such as the tidal (潮汐的) waves sometimes caused by earthquakes under the sea. But the waves most of us know are caused by winds blowing over the sea .
Now let’s learn some physical (自然地理學的) things about it. A wave has height, from low point to high point . It has length (長度)--the distance from this high point to that of the following wave. The period of the wave means the time it takes for succeeding high points to pass a fixed point. None of these things stays the same--for all depend upon (依靠)the wind, upon the depth (深度) of the water and many other matters.
The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position (原先的位置). And it is lucky that this is so. For if the huge groups of water that make up a wave really moved across the sea, sailing would be impossible. If we want to find the speed of a wave, we may use the following way : Speed =" wavelength" × frequency (頻率).
Here, wavelength is the distance between two high points , frequency means the number of cycles per second

As a father, I always do my best to help my son, Peter. I like to help him with his study. I encourage him to join team sports. I send him to the summer camp if he wants to go. I also teach him to be both a good student and a useful man.

He used to make me feel proud. I often thought he was the best son and I was the best father in the world.

However, things changed two years ago. It was Peter’s 12th birthday. My wife and I bought him a computer as a present. We thought it was necessary for him to learn how to use a computer in the modern world. We knew that some children were addicted (上癮的) to computer games and that they didn’t study or work at all. Someone said that computers and the Internet were bad for children, but I didn’t worry about it. I trusted (信任) my son. I believed that he could control himself. Peter did very well at first. He played computer games, but for only two hours every week. Most of the time he studied or wrote articles on the computer. We felt very happy to see that.

When we finally learned that Peter was also addicted to computer games, it was too late. He didn’t like studying at all. He no longer joined team sports. Sometimes we even couldn’t find him at night. He spent several days and nights at the Internet cafe. We tried everything to help him, but nothing worked. What should we do?
