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 (波紋) 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(大壩) to block the water and send it through a large wheel called a turbine(渦輪). The turbine can then power an electrical generator(發電機).
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(資源) 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!

【小題1】We can learn from the passage that__________________.
A.almost every country is making use of the wave power at present
B.it is necessary for us to develop wave power instead of oil and coal
C.wave power will be sure to make some bad influence on sea animals

One of the greatest mysteries on Earth is the statues which stand on Easter Island. Easter Island, which was almost uninhabited when it was discovered on Easter Day in 1722 by a Dutch captain, is the most distant island in the world covered with hundreds of giant statues, each weighing several tons and some standing more than 30 feet tall.
Who built these statues and why and how did they get there? Nobody knows the answer for sure.
One theory suggests that Easter Island was first inhabited by Polynesians, who traveled thousands of miles in their canoes(獨木舟)in 400 A.D. However, the ocean currents(洋流)which carried them there would not take them back, so that they could not leave.
The statues appear to have been made out of the top edge of the walls of a volcano on the island. Then, it may have been rolled or dragged down to the foot of the volcano(火山). Then, it was stood upright(直立)and ropes were tied around it, which was made to act as a pulley(滑輪). Over a period of months, a statue could be walked for miles down to the ocean. Finally, it was placed in line with other statues, all of them looking towards the center of the island.
This process was difficult. If a statue fell over, it was too heavy to be pulled upright again, so the islanders went back and carved another statue.
The population of Easter Island must have reached 11,000. Later, the resources of the island were used up and people began fighting and eating each other. Work on the statues stopped and the statues were knocked over. When the first Europeans finally arrived on the island, most of these people had died out.
【小題1】This passage is mainly about ________ .
A.the discovery of Easter IslandB.the statues on Easter Island
C.the history of Easter IslandersD.the earliest population on Easter Island
【小題2】 Which of the following correctly tells of the possible working process after a statue was made?
a. It was stood upright and ropes were tied around it.
b. It was walked for miles down to the ocean.
c. It was placed in line with other statues.
d. It was moved to the foot of the volcano.
A.c-d-a-bB.d-b-a-cC.a-c-b-dD.d-a-b-c
【小題3】 It’s not a fact that ________ .
A.Easter Island is the most distant island in the world
B.Easter is the name of a holiday
C.not all the statues were placed in a line
D.the island was once rich in natural resources
【小題4】The underlined word uninhabited most probably means ________.
A.mysteriousB.lost
C.unknown to the worldD.with no people living there

A wise man used to go to the ocean to do his writing. He had a habit of walking on the beach every morning.

One day, when he was walking along the shore(海岸), he saw a young man moving like a

dancer. He smiled to himself at the thought that someone would dance on the beach. So he began to walk faster to catch up.

As he got closer, he saw that the young man wasn’t dancing, but instead he was reaching down to the shore, picking up something and very gently throwing it into the ocean.

He called out, “Good morning! What are you doing?” The young man stopped, looked up and replied, “Throwing starfish in the ocean.” “I guess I should have asked, why are you throwing starfish in the ocean?”

“The sun is up and the tide(潮汐)is going out. And if I don’t throw them in, they’ll die.”

“But, young man, don’t you realize that there are miles and miles of beach and starfish all along it. You can’t possibly make a difference!”

The young man listened politely. Then he bent down, picked another starfish, and threw it into the sea, and said, “It made a difference for that one.”

There is something very special in each and every one of us. We have all been gifted(賦予)

with the ability to make a difference.

We must each find our starfish. And if we throw starfish wisely and well, the world will be better.

1.What was the wise man used to doing every morning?

A.Taking a walk on the shore.

B.Watching the young man dance.

C.Meeting up with the young man.

D.Helping the young man pick up starfish.

2.Why did the young man throw the starfish into the ocean?

A.To have fun.

B.To study starfish.

C.To feed some fish.

D.To save starfish.

3.What can we learn from the story?

A.Each of us should learn to protect starfish.

B.People living on the shore always try to save starfish.

C.Each of us has the ability to make an important effect on something.

D.People can come up with some good ideas when walking on the shore.
