As we all know, the ocean moves. But waves breaking on the beach make the ocean fun. When you stand on the shore and look at the waves, it seems like the water is moving towards you. But the water is not really moving forward. The moving you see is wave energy. And wave energy comes from the wind.
Let’s think about how this works. As wave energy passes through the water, the energy makes particles （粒子） of water move up and down. Just give you an example of a wave passing under a basketball. We put a basketball on the sea. When the wind blows, a wave comes from behind the basketball. The basketball moves up to the top with the wave. Then the wave continues and leaves the basketball behind. The basketball looks lower, but it doesn’t move forward. That’s because the wave energy just moves the water which is under the basketball.
　  So why can you see a wave knock you down on the shore？When a wave moves toward the shore, the bottom of the wave slows down because it meets the ocean floor. But the top, which is called crest(浪峰), keeps moving. The different action causes the wave to fall over or break onto the shore. If a wave is very large, it carries a lot of energy when it hits the land. As time goes by, waves can break up and carry away the rocks and other things on the shore. Shorelines are changing all the time because of wave action.
【小题1】______ is really moving forward when you look at the wave.

A 10-year-old boy decided to study judo (柔道), although he had lost his left arm in a car accident.

　　The boy began lessons with an old Japanese judo teacher, Mr. Tanaka. The boy was doing well, but his teacher had taught him only one move in three months of training.

　　“Mr. Tanaka,” the boy finally asked, “shouldn’t I be learning more moves？”

　　“This is the only move you know, but this is the only move you’ll ever need to know,” his teacher replied.

　　Several months later, Mr. Tanaka took the boy to his first tournament (锦标赛). The boy won his first three matches, using his one move to win. The boy was now in the finals, and was amazed by his own success.

　　This time, his opponent (对手) was bigger, stronger, and more experienced. The referee (裁判) wanted to stop the match.

　　“No,” the teacher insisted, “let him continue.” Soon, his opponent lowered his guard. At that moment the boy used his move to pin (钉住) him. The boy won the match and became the champion.

　　On the way home, the boy and his teacher reviewed every match. Then the boy asked what was really in his mind.

　　“Mr. Tanaka, how did I win the tournament with only one move？”

　　“You won for two reasons,” his teacher answered. “First, you’ve almost mastered one of the most difficult throws in all of judo. And second, the only defense (防守) for that move is for your opponent to catch your left arm.”

　　The boy’s biggest weakness had become his biggest strength (优点).
