The ocean can be a great place to swim and play, it may also be useful in another way. Some scientists think that waves could help make electricity.
“Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave?” asked Jamie Taylor of the Wave Energy Group in Scotland. “There is certainly a lot of energy in waves.”
Scientists are working on using that energy to make electricity. The United States and a few other countries have started doing research on wave energy, and it is already being used in Scotland.
Most waves are created when winds blow across the ocean. “The winds start out by making little ripples (波纹) in the water, but if they keep on blowing, those ripples get bigger and bigger and turn into waves,” Taylor said. “Waves are one of nature’s ways of picking up energy and then sending it off on a journey.”
When waves come towards the coast, people can set up dams(大坝) to block the water and send it through a large wheel called a turbine(涡轮). The turbine can then power an electrical generator(发电机).
We will never run out of wave power. Besides, wave energy does not create the same pollution as oil and coal do.
Oceans cover three quarters of the earth’s surface. That would make wave power seem perfect for creating energy around the world. But there are some disadvantages that need us to pay more attention to.
Jamie Taylor said that wave power still cost too much money. He said that its influence on animals in the sea is still unknown. Besides, wave power would get in the way of fishing and boat traffic.
With more research, “Many of these problems might be solved,” Taylor said. “Finding more energy sources(资源) is very important, for traditional sources of energy like oil and gas may run out some day.”
In the future, when you turn on a light button, an ocean wave could be providing the electricity!

【小题1】We can learn from the passage that__________________.

Sophia Wu, 25, is a young Chinese woman who does business with her family in Santiago, Chile (智利). On February 27, she experienced a night that she will never forget.

　　"I was asleep and was woken up by powerful shaking at around 3:30 in the morning. My whole room was moving and I couldn't stand still. I wanted to run downstairs and go outside, but suddenly the wall got broken and the lights in the room went out. The room became so shaky that I couldn't move at all."

　　That night an 8.8-magnitude (震级) earthquake hit Chile. Buildings and bridges fell down. Electricity (电) and water services shut down. The Chilean Red Cross reported that about 500,000 homes were destroyed and more than 800 people died.

　　The earthquake has been the fifth strongest since 1900. More than 90 aftershocks (余震) followed the earthquake. A tsunami (海啸) was set off in the Pacific Ocean by the earthquake.

　　Scientists say that there are about 500,000 earthquakes in the world each year. Of these, only 20% are felt, and 100 of them cause damage.

　　So far, scientists haven't found a way to predict earthquakes. But you can learn to protect yourself during an earthquake. The most important thing to remember is to drop, cover and hold on. So remember to drop to the floor, get under something for cover and hold onto something strong during the shaking.
