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

PLAYA GRANDE, COSTA RICA? This resort town was long known for Leatherback Sea Turtle （棱皮龟） National Park, nightly turtle beach tours and even a sea turtle museum．However, on a beach where dozens of turtles used to nest on a given night , scientists spied only 32 国leatherbac,ks all of last year．

       With leatherbacks threatened with extinction （灭绝）, Playa Grande's turtle museum was abandoned three years ago and now sits among a sea of weeds．And the beachside ticket office for turtle tours was washed away by a high tide in September．"We do not promote that 'as a turtle tourism destination anymore because we realize there are far too few turtles to please,” said Alvaro Fonseca, a park ranger （管理员）．

       Even before scientists found temperatures going up over the past decade, sea turtles were threatened by beach development, drift net fishing and Costa Ricans' interest in eating turtle eggs．Btu climate change may cause the most serious harm to an animal that has lived in the Pacific for 150 million years．

       Sea turtles are sensitive to numerous effects of warming．They feed on reefs, which are dying in hotter seas．They lay eggs on beaches that are being covered by rising seas and more violent waves．

       More uniquely their gender （性别）is determined, not by genes but by the egg's temperature during development．Small rises in beach temperatures can result in ail-female populations, obviously problematic for survival．If the sand around the eggs hits30 degrees Celsius, the gender balance shits to females: at about 32 degrees they are all female．Above 34, you get boiled eggs．

       On some nesting beaches, scientists are artificially cooling nests with shade or irrigation and trying to protect broader areas of coastal property from development to ensure that turtles have a place to nest as the seas rise．

Why does the resort: town stop promoting its turtle tourism?

       A．It decides not to disturb the turtles' normal life．

       B．Tourists have lost interest in watching turtles．

       C．There are only very few turtles now．

       D．The turtle museum was destroyed by a high tide．

Which of the following is the major factor in the turtles endangerment?

       A．The local's eating habit．              B．Drift net fishing

       C．Beach development                  D．Global warming
