Today, after many days of practice and lots of matches, we entered the basketball final.
I was the leader of the team. At the very beginning, one student from our team got the ball and quickly shot a basket. Oh, it went in, 2:0. All our classmates cheered.
But after a few minutes there were some mistakes and we lost eight points. I changed two players, but it didn’t help.
At that time all our teammates felt worried and we even quarreled with each other angrily.  “It’s no use crying over spilt milk!” I shouted, “We must face it !” Let’s think about our mistakes and stop making them!”
We had a short meeting . The second half of the match began. There was a big change. At first, our team got the ball and I shot from the three-point line at once. The ball did a beautiful curve and went straight into the basket.
I become very confident. The other team was still very strong.
A good chance came! I got the ball again and shot into the basket! 12:9! I couldn’t believe my eyes! Am I that good at shooting? How could I get so many points?
We stayed in the lead. Finally the score was 18:16. We won!

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.
