International experts meeting in Australia say global carbon emissions (排放) can be reduced by more than 50 percent through simple energy saving measures. People at a conference in Australia, which increasingly relies on coal for power, say that reducing power consumption is an affordable way to both cut energy costs and reduce pollution.
While many nations turn to cheap and dirty energy sources, such as coal, to meet their increasing energy needs, analysts in Australia say the best way to meet those needs is to improve energy efficiency.
A range of simple solutions include using energy-efficient homes, household appliances and lighting, and driving electric cars. Encouraging homeowners and office workers to switch off their televisions and computers at the end of the day is also seen as an effective way to save electricity.
Grayson Heffner, from the Paris-based International Energy Agency, says reducing consumption could greatly cut global carbon emissions. He calls efficiency strategies (策略) the “soft giant” of clean energy.
“We forecast that energy efficiency will deliver something like three-quarters of the greenhouse gas emissions reductions over the next 20 years. So in the short term energy efficiency is the main way that we reduce greenhouse gas emissions but oftentimes it is not so importantly stressed in the discussions,” said Heffner.
Energy experts working in China say the government is making significant cuts in power usage.
Wan Xingwang, a Beijing-based representative of the Energy Foundation, a U.S. non-government organization, says the results have been impressive.
“In the past five years China achieved about 19.1 percent of energy reduction of its GDP. That translates to something like more than 600 million tons of coal savings,” said Wan Xingwang.
While most nations have some sort of government-sponsored energy efficiency programs, energy analysts say initiatives (主动性) by individuals and companies can also help cut demand.
Steven Nadel, executive director of the American Council for an Energy Efficient Economy, a non-profit group based in Washington, says other developing nations are recognizing the benefits of cutting power consumption and taking action.

2.Which of the following cannot help to reduce energy consumption effectively?

A．Using electronic products in small size.

B．Using more electric cars.

C．Turning off computers after work.

D．Building energy-efficient houses.

3.What can we learn from what Grayson Heffner said?

A．75% of the greenhouse gas emissions can easily be cut in the next 20 years.

B．Ways to reduce greenhouse gas emissions should be discussed.

C．Using clean energy is the strategy to cut global carbon emissions.

D．The key to reducing greenhouse gases in the short term is to improve energy efficiency.

4.According to the last two paragraphs, which of the following statements is true?

A．The programs reducing energy consumption shouldn’t be sponsored by individuals and companies.

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!
68．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．
69．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 perfect for creating energy around the world
D．wave power doesn’t create any pollution
70．The underlined word “drawbacks” probably means ______．
A．regrets      B．adventures       C．disadvantages          D．difficulties
71．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．
