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 shore, people can set up dams or other barricades 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(fā)電機(jī)) .
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!
1.Which of the following is NOT true?
A.Wave power costs too much money.
B.Wave energy creates the same amount of pollution as other energy sources.
C.Wave power affects fishing and boat traffic.
D.Wave power may affect marine animals.
2.We can infer from the passage that ______.
A.finding new energy sources like wave energy is important
B.wave energy is a resource that will never run out and is used all over the world
C.wave power is perfect for creating energy around the world
D.wave power doesn’t create any pollution
3.The underlined word “drawbacks” in the seventh paragraph probably means______.
A.regrets B.a(chǎn)dventures
C.disadvantages D.difficulties
4.What can be the best title for the passage?
A.How to Get Electricity by Waves.
B.A Huge Resource of Energy.
C.Can Waves Make Electricity?
D.The Disadvantages of Wave Energy.

It may not be as easy as you think to build a foundation for your child of family values. Often we believe that our child will pick up on our values if they live in the same home. While they may pick up many of our values, parents need to remember they are not the only influence in their child’s life. These outside values often compete with family values for your child’s attention. If we do not make a conscious effort to instill our values into our children, they may not get instilled at all.
I wish I had learned that lesson a little earlier. I thought if I lived my values for my children they would pick them up and make their own. Sometimes this happened and sometimes it didn’t. I often see twenty-something “kids” who have no faith in many of the values of their family in favor of the values of their friends. Children will often pick up the negative you show quicker than the positive, so the positive things need extra focus to set them.
Some of the influences your children face every day include their church, their school, their friends, any clubs or sporting groups they are part of and more. Kids spend many hours a day at school and with their friends. Sometimes in the business of life, we suppose our children will obtain that foundation we want for them.
Instilling a foundation of family values to sustain(維持) your child requires more than living it in front of them. That is important, but building up your child with this important foundation must become intentional.
That means we plan times to gather as a family. We plan activities together that show the values we want to pass on. We talk about our values; we live our values; we discuss the values of others and how they differ from ours; we constantly look for opportunities and make our own opportunities to share these values in word or deed with our children.
Family values give our children a foundation to build upon. It helps them know they are loved and gives them a sense of belongings. Upon this sure foundation, they can spread their wings and grow to become parents who share these same values with their own children.
1.The underlined word “instill our values into” in the 1st paragraph probably means “______”.
A. get our ideas out of B. impress our ideas on
C. collect our ideas for D. force our ideas upon
2.We can learn from the passage that children ______.
A. sustain their family values easily
B. will hold their family values with age
C. often discuss family values of others
D. accept negative values more quickly
3.Family values can be passed on if ______.
A. we live with our children
B. parents show positive things
C. parents foster them intentionally
D. we plan times to gather with other families
4.The passage mainly tells us about ______.
A. the importance and the way to pick up family values
B. a lesson the writer learned in educating his(her) kids
C. the influences the children face while growing up
D. some negative and positive family values
