20.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 large 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 wave 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!

34.The underlined word"drawbacks"in the seventh paragraph probably meansC.
A.regrets
B.adventures
C.shortcomings
D.difficulties
35.What can be the best title for the passage?C
A.How to Get Electricity by Waves
B.A Huge Resource of Energy.
C.Can Waves Make Electricity?
D.The Disadvantages of Wave Energy.
分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了科学家认为波浪能会成为未来一种新的无污染的能源,如新寻找新能源是十分重要的.
解答 32.B.细节理解题.根据文章The resource is huge.We will never run out of wave power,besides,wave energy does not create the same pollution as other energy sources,such as oil and coal可知波浪能不会和其他能源一样造成污染;故选B.
33.A.细节理解题.根据倒数第二段Finding more energy sources is very important,for traditional sources of energy like oil and gas may run out some day可知找到像波浪能源新能源是重要的;故选A.
34.C.词义猜测题.根据文章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可知海洋覆盖了地球表面的三分之四,这将使波能在世界各地创造能源似乎是完美的,但也存在一些缺点;意为缺点;故选C.
35.C.推理判断题.根据文章Some scientists think that waves could help make electricity可知最佳标题为波能发电吗?故选C.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
