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.

Dear Disney,

Last weekend, the four members of my family spent an enjoyable holiday at the Magic Kingdom - Disneyland. And one event made our visit seem truly magical.

We got to the front of the line at Space Mountain, only to find out that our little daughter Gloria couldn't take her ice-cream on the ride. We were so excited that we all forgot ice-cream was not allowed on the ride.

Gloria broke into tears and we all had no idea what to do. Then Murphy, one of the staff(员工) members, came over. She bent down and told Gloria that she would hold the ice-cream for her and give it to her when she finished the ride. Gloria said, "Promise?" Then she gave Murphy her ice-cream, and she completely enjoyed the ride.

Sure enough, as we walked out the exit, there was Gloria's new friend with "her" ice-cream. Now you and I both know what happened, because we know that an ice-cream won't last twenty minutes on a summer afternoon in Florida. Murphy knew what time we would get off the ride; she went to the nearest shop and bought a brand-new ice-cream thirty seconds before we walked out the exit. Gloria said, "Thank you," but I'm sure she thought it was the same ice-cream.

We know that someone tried hard to make our visit special. Thanks so much for going above and beyond!
