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!

For the 17 years my life was very happy. Then the first sad thing happened. My mother became very ill. Just before she died, she asked Elizabeth and me to go to her room. She said, “Victor and Elizabeth, I’m very happy because you love each other, and because one day you’ll get married. Everyone in the family loves you, Elizabeth. Will you take my place in the family, my dear? I can die happy if you look after them when I have gone.”

My mother died and we were very sad, because we loved her so much. Elizabeth was brave and helped us; her sweet smile gave us some happiness in the unhappy days after my mother’s death. The time came for me to go to university(大学). I didn’t want to leave my sad family, but we all knew that I should go. It was hard to leave, too, because the parents of my good friend Henry would not let him go to university with me. So I had gone alone.

On my first day at university I met Professor Waldman. He gave a wonderful talk to all the students. He ended his talk by saying, “Some of you will become the greatest scientists of tomorrow. You must study hard and discover everything that you can.”

After the professor’s talk, I thought very carefully. I remembered the storm when I was 15; I remembered how the lightning had destroyed the tree. From then on, I wanted to use electricity to help people, and I wanted to discover the secrets of life. I decided to work on these two things.

I started to work the next day. I worked very hard and soon Professor Waldman and I realized that I could learn to be a very good scientist.

The professor and other important scientists helped me. I was interested in my work and I did not take one day’s holiday during the next two years. After two years, I had discovered many things and I built a scientific machine that was the best in the university. My machine would help me answer the most important question of all. How does life begin? Is it possible to put life into dead things? To answer these questions about life I had to learn first about death. I had to watch bodies from the moment when they died and the warm life left them. In the hospital and in the university, I watched the dying and the dead. Day after day, month after month, I followed death, so it was a dark and terrible time.

I built a tall mast(桅杆)about 150 metres high, which is higher than the tallest building in the city, to catch lightning and send the electricity down to my machine in the lab. I believed I could use that electricity to give life to things that were dead.

Then one day, the answer came to me. Suddenly I was sure that I knew the secret of life.

1.Which of the following is TRUE according to the passage?

A.Elizabeth married shortly after Victor’s mother died.

B.Elizabeth was a brave girl who loved Victor and gave him much help.

C.Victor’s mother was very angry when she knew he loved Elizabeth.

D.Victor did not want to leave his family because his mother died not long before.

2.Victor did all the following during his research in the university EXCEPT that ______.

A.he discovered many things and built a scientific machine

B.he learnt much about death both in the hospital and in the university

C.he worked hard and took only one day’s holiday during the next two years

D.he built a tall mast to catch lightning and send the electricity down to the lab

3.According to the writer, the secret of life is to _______.

A.give life to things that were dead

B.build the best machine to learn about death

C.use electricity to help others

D.become the greatest scientist of tomorrow

4.Which is the correct order about the life of Victor?

① Victor’s mother passed away.

② Victor got help from the professor and other scientists.

③ Victor went to university and attended the professor’s talk.

④ Victor found the answer to giving life to things that were dead.

⑤ Victor experienced a storm, seeing the lightning destroying the tree.

A.①②③④⑤                           B.⑤①②④③

C.①③②⑤④                           D.⑤①③②④

In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.
Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.
Until now, even the most advanced (先进的) robot was almost certain to break down when it was damaged (毁坏). That is because its computer inside simply doesn’t know how to make the machine work after its shape has changed. 
To deal with this problem, the scientists put eight motors (发动机) and two sensors (传感器) that read how the machine is working. They all give signals to the machine’s software. Using this information, the computer can then figure out the machine’s shape at any moment.
The new technology is a big advance in robot-making, scientists say, and it’s far from scary. It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.
“It has been difficult to design robots that can work well when the environment changes or when it’s damaged,” says Olaf Sporns of Indiana University in US. “With this work, we are nearer to solving this problem.”
【小题1】Why do robots easily break down when they are damaged?

A.They cannot repair themselves.
B.The computer has changed a lot.
C.They have no computers inside.
D.The computer cannot work if the robot changes.
【小题2】The new technology(技术) allows the robot to        .
A.keep working after being damaged
B.tell people where it is
C.do house work for humans
D.remember a lot of information
【小题3】The underlined word “them” in Paragraph 5 refers to       .
A.sensors B.robotsC.scientistsD.arms and legs
【小题4】How do the sensors in the robot work?
A.They can replace the computer when it’s broken.
B.They help the computer learn the robot’s condition.
C.They can find out where the damage comes from.
D.They can send signals to the person who uses the robot.
