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!

The size and shape（外形）of your ears show your character（性格）more than any other part of the face. Other parts of the face change shapes as we get older，but ears do not change their shapes. They only change in size.
Reading people’s character from their ears is a very old science. In the past people thought that a person’s ears with colour was dangerous. They also thought that the shape of the ears showed if a person was musical or not. Today，too，many people believe that the size and shape of the ears help you know if a person is musical.
Ears are all different，and each different thing has a meaning. Next time you look at a person，see if his or her ears are large，medium-size，or small. Look at the lobes（耳垂）.Do they stick to the face? Ears that are always red mean that a person may get angry easily. Ears that are always cold and  nearly white colour mean that a person has a nervous（神经质）character.
1. Reading people’s character from their ears is____________ .
A．only for music      B．an old idea   C．very new     D．a good way to talk with others
2. When a baby is born,___________ .
A．his / her ears are red               B．his / her ears will not change all the life
C．his / her ears will not change in shape  D．he / she will get large ears
3. When one’s ears are red，it means_____________ .
A．he is a kind man                B．he is very happy
C．he may get angry easily             D．he drinks too much
4. Which may be the best title of the article?___________.
A.Looking at a person in the right way.     B.Ears and colours.
C.The change of ears.                   D.Ears and characters
5.If you look at someone’s ears，the right way is____________  .
A．to look at his face，ears and nose     
B．to look at the size，colour，and shape
C．to look at his mouth，eyes and nose
