问题     Answer questions by referring to the radio reports on saving energy.
    Note: When more than one answer is required, these may be given in any order. Some choices may be required more than once.
    A = Report 1
    B = Report 2
    C = Report 3
    D = Report 4
    Which report(s) say(s) that
A
Report 1
    It is estimated that the world’s consumption of energy will increase by 60 percent over the next 20 years. Today half of U.S. electricity is generated by coal, which is responsible for over 80 percent of carbon dioxide emissions, a main contributor to global warming. The wind power industry is growing rapidly: it has increased 23 to 30 percent in each of the last five years. It is clean, abundant, ever-renewable, and free from producer boycotts or embargoes. Today only one percent of U.S. energy comes from wind. It provides more than 20 percent of Denmark’s energy. The U.S. hopes to match that within 20 years. But there are many obstacles to making wind power a true alternative to oil. Industry experts say inconsistent government policies have discouraged investors. And there are not enough transmission lines to get the power generated by wind onto the grid. There is a greater dilemma now, which is how to move the wind (power) from the windiest, most valuable, effective places to locate the actual wind farms to the load centers or the cities that need that power. There are also political objections to wind power. Another is that many people do not want to live near wind turbines, which they consider unsightly, loud and harmful to birds and other wildlife. With oil and natural gas prices rising rapidly, the political climate for alternative energy development seems to be gaining momentum in the U.S. More than 22 states have ordered their traditional utility companies to diversify into alternative sources of energy.

Report 2
    Johns Hopkins University is considered one of America’s most beautiful college campuses. But many of the old buildings could be made far more energy efficient, saving both money and precious natural resources. It develops new initiatives to conserve water and electricity, encourage recycling, and reduce the University’s "environmental footprint". Mr. Bookhart says that to minimize the environmental impact, he will need to build coalitions with students, and faculty members. Mr. Bookhart is full of ideas for modifying even the smallest energy-wasting systems on campus, and by putting in one of those devices that will probably help us save about 30 to S0 percent on our electricity costs. Another idea is to convert rooftops here into so-called "Green Roofs". Green roofs are natural vegetative covers that help control storm water runoff and reduce energy use by insulating buildings from temperature extremes. Bookhart’s energy savings projects also promise substantial economic benefits. The University saw its electric rate rise 36 percent last year, and anticipates an equivalent increase this year. What is happening at Johns Hopkins is beginning to be seen at other U.S. Universities as well, as campuses that always appeared green are about to become greener still.

Report 3
    California is facing a power emergency in the wake of record high temperatures. Air conditioning units across the state are set on "high" and consumers are being urged to conserve electricity by curbing non-essential use. Light-emitting diodes are more efficient than today’s incandescent bulbs because they shed less heat. The city is spending $4 million to begin replacing lights at all 4,600 of its intersections. It will take five years, but is expected to save $2.2 million per year. Conserving electricity has become a critical issue in California this month with record electrical use in the wake of record high temperatures. Another way California is attempting to save electricity is by alerting consumers to the presence of so-called "energy vampires" in their homes. Nearly everything plugged into a wall socket—from toasters to cell phone chargers—drains away about two dollars worth of "standby" power each year. It adds up to huge savings. It’s better to educate and to tell consumers that when something is plugged in, even if it’s used or not being used, it’s sucking energy, and that also shows up on the utility bill.

Report 4
    Asia must use energy more efficiently because as it develops the region will play a big role in climate change. Asia’s growth has brought benefits to the poor, but has also put a serious strain on the environment, resources and energy supplies. Between 1973 and 2003, Asia’s energy consumption grew by 230 percent, compared with an average worldwide increase of 75 percent. As a consequence, the region’s share of greenhouse gas emissions has risen from less than one- tenth of global emissions to nearly one-quarter. Greenhouse gas, a byproduct of emissions from burning oil, gasoline, and coal, contributes to global warming. Rising global temperatures are expected to alter rainfall levels, affecting crop yields and water supplies. In addition, in many Asian countries, sharply rising energy consumption is worsening air pollution, and damaging public health. The ADB president argues that Asia must expand its access to energy to maintain its rapid growth and to keep lifting people out of poverty, but energy production and consumption needs to move to a more sustainable path. The reality of Asia’s impact on global warming can no longer be ignored. The ABD has planned something called the Carbon Market Initiative, which will help developing countries with financing for cleaner energy technologies.
选项 A、 
B、 
C、 
D、 
答案A,D
解析 这句的关键词是global warming，在A和D中也可以找到global warming，而且句意相似，所以判断答案是A和D。
