In summer, millions of people will head for the beach.And while 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? Or have you jumped in the water and felt the energy as waves crashed over you?” asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh in Scotland.“There is certainly a lot of energy in waves.”
Scientists are working on using that energy to make electricity.
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 shore, people can set up dams or other barricades to block the water and send it through a l
arge wheel called a turbine (涡轮) .The turbine can then power an electrical generator (发电机) .
The United States and a few other countries have started doing research on wave energy , and it is already being used in Scotland.
The resource is huge.We will never run out of wav
e power, besides, wave energy does not create
the same pollution as other energy sources, such as oil and coal.
Oceans cover three quarters of the earth’s surface.That would make wave power seem perfect for creating energy around the world.There are some drawbacks, however.
Jamie Taylor said that wave power still cost too much money.He said that its effects on animals in the sea were still unknown.Plus, wave power would get in the way of fishing and boat traffic.
With more research, however, “many of these problems might be overcome,” Taylor said.“Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is growing quickly throughout the world.Finding more energy sources 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 switch, an ocean wave could be providing the electricity!

Whether they’re project documents, trade journals, blogs, business books or ebooks, most of us read regularly as part of our jobs, and to develop our skills and knowledge.
But do you ever read what should be a useful document, yet fail to gain any helpful information from it? Or, re-read something several times to get a full understanding of the content? If so, look at the following strategies (策略) that will help you read more effectively.
●Think About What You Want to Know
Before you start reading anything, ask yourself why you’re reading it. Are you reading with a purpose, or just for pleasure? What do you want to know after you’ve read it? Once you know your purpose, you can examine the resource (资源) to see whether it’s going to help you.
Ask yourself whether the resource meets your needs, and try to work out if it will give you the right amount of knowledge. If you think that the resource isn’t consummate, don’t waste time reading it.
●Know How Deeply to Study the Material
Where you only need the shallowest knowledge of a subject, you can skim material. Here you read only chapter headings, introductions, and summaries.
If you need a moderate (中等的) level of information on a subject, then you can scan the text. This is when you read the chapter introductions and summaries in detail. You can then speed read the contents of the chapters, picking out and understanding key words and concepts.
Only when you need full knowledge of a subject is it worth studying the text in detail (细节). Here it’s best to skim the material first to get an overview of the subject. This gives you an understanding of its structure, into which you can then fit the detail gained from a full reading of the material.
1.Why should we know our purpose before reading?
|
A.Because we can develop our skills and knowledge. |
|
B.Because we can get a full understanding of the content. |
|
C.Because we can avoid re-reading something several times. |
|
D.Because we can check it out whether the material will be helpful. |
2.What does the underlined word “consummate” in the 5th paragraph mean?
|
A.Legal. |
B.Natural. |
C.Perfect. |
D.Formal. |
3. According to the depth to study the material, how many reading strategies are mentioned?
|
A.2. |
B.3. |
C.4. |
D.5. |
4.The best title for this passage should be ______.
|
A.Reading Strategies |
|
B.Think About What You Want to Know |
|
C.Know How Deeply to Study the Material |
|
D.How to Develop our Skills and Knowledge |
