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!

Which of the following is NOT true?

       A．Wave power doesn’t cost too much money．

       B．Wave energy is so clean that it doesn’t create the same amount of pollution as other energy sources．

       C．Wave power affects fishing and boat traffic．

       D．Wave power may affect marine animals．

We can infer from the passage that ______．

       A．finding more new energy sources is not necessary because of wave energy

       B．wave energy is a resource that will never run out and is used all over the world

       C．wave power is not quite perfect for creating energy around the world

       D．wave power doesn’t create any pollution

The underlined word “drawbacks” probably means ______．

       A．regrets     B．adventures       C．disadvantages   D．difficulties

What can be the best title for the passage? 

       A．How to Get Electricity by Waves     

       B．The advantages of Wave Energy

       C．Can Waves Make Electricity?        

       D．The Disadvantages of Wave Energy

We use the Internet for many things: business, shopping, writing letters, talking to people, finding information and so on. In recent years, a new kind of English has grown on the Internet. There’s no real word for it yet, so we’ll call it e-talk. People don’t like typing too much. To save time, they turn phrases into a few letters (called acronyms). Acronyms are often used in chat rooms(聊天室). Some of them are:

BTW(by the way);  BRB(be right back);  LOL(laughing out loud);  IMO(in my opinion)

People also use many abbreviations. They are shortened forms of words. Some common abbreviations are:

info(information);   puter(computer);    pic(picture);     sec(second)

We ususally don’t see people when we communicate on the Internet, so people have new ways to show feelings. Most people use their keyboards to draw “feelings”, such as:

:-) (happy);     ;-)(joking);        :-((sad);       :-O(surprised)

These days, many forums(论坛)have picture feelings. For example:

            

(happy)              (sad)               (angry)               (cool)

There are even whole new words, like ”newbie’s” (someone who is new on a chat board or forum). When you write something bad about someone else, it’s called “flaming” the person.

It takes time for people to get used to e-talk. Also, different groups on the Net have their own special ways of communicating. Newbie’s sometimes have to ask other people what they mean. As the Internet grows, e-talk will continue to grow and change.

Why do people type acronyms?

A. To show their feelings.      B. To make jokes.

C. To save time.                D. In this way newbie’s won’t understand them.

What does “BTW, my computer is not working well, :-( ”mean?

A．The person is happy about getting a new computer.

B. The person has to go away from his/her computer.

C. The person is angry at somebody.

D. The person is sad that his computer is having problems.

If someone is angry, what may he type?

A.      B. BRB          C. LOL        D.

E-talk will probably_______.

A. keep changing                       B. stay the same

C. be used by people on the telephone       D. be easy for newbie’s to understand.
