听力原文：Prompted by the oil crises of the 1970s, a wind-power industry flourished briefly

in the United States. But then world oil prices dropped, and funding for research into renewable energy was cut. By the mid-1980s US interest in wind energy as large-scale source of energy had almost disappeared.The development of wind power at this time suffered not only from badly designed equipment, but also from poor long-term planning, economic projections that were too optimistic and the difficulty of finding suitable locations for the wind turbines.

The sufferings of wind power industry in the mid-1980s in the United States could be attributed to the following EXCEPT ______.

A．oil crises of the 1970s

B．the drop of oil prices

C．lack of funding for research into renewable energy

D．loss of interest in wind energy as a widely-used source of energy

Renewable Energy Sources Today petroleum （石油)provides around 40% of the world's energy n

Renewable Energy Sources

Today petroleum (石油)provides around 40% of the world's energy needs, mostly fuelling automobiles. Coal is still used, mostly in power stations, to cover one-quarter of our energy needs, but it is the least efficient, unhealthiest and most environmentally damaging fossil fuel (矿物燃料). Natural gas reserves could fill some of the gap from oil, but reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. Less-polluting renewable energy sources offer a more practical long-term energy solution. "Renewable" refers to the fact that these resources are not used faster than they can be replaced.

Hydroelectric (水力发电的)power is now the most common form. of renewable energy, supplying around 20% of world electricity. China's Three Gorges Dam is the largest ever. At five times the size of the US's Hoover Dam, its 26 turbines (涡轮机)will generate the equivalent energy of 18 coal-fired power stations. It will satisfy 3% of China's entire electricity demand.

In 2003, the first commercial power station to use tidal (潮汐的)currents in the open sea opened in Norway. It is designed like windmill (风车), but others take the form. of turbines.

As prices fall, wind power has become the fastest growing type of electricity generation-quadrupling (翻两番)worldwide between 1999 and 2005. Modern wind farms consist of turbines that generate electricity. Though it will be more expensive, there is more than enough wind to provide the world's entire energy needs. Wind farms come in onshore and offshore forms. They can often end up at spots of natural beauty, and are often unpopular with residents. And turbines are not totally harmless-they can interfere with radar, alter climate and kill sea birds. Scotland is building Europe's largest wind farm, which will power 200, 000 homes. The UK's goal is to generate one-fifth of power from renewable sources, mainly wind, by 2020. But this may cause problems, because wind is unreliable.

According to the passage, which of the following is the most polluting energy resource？

A．Petroleum.

B．Coal.

C．Natural gas

D．Water.

根据下列材料请回答 51～65 题：

Debate over the Use of Renewable Energy

Amusable of Rockefeller University in New York，US says the key renewable(可再生的) energy sources，including sun，wind and bibfuls, would all require vast amounts of land developed up to large scale production—unlike nuclear power.That land would be far better________(51)alone，he says.Renewable look_______ (52) when they are quite small.But if we start producing renewable energy on a large________(53), the fallout(结果)is going to be horrible.

Amusable draws his conclusions by analyzing the amount of energy that renewable natural gas and nuclei(原子核)can________(54)in terms of power per square meter of land used.Moreover，he claims that_________(55)renewable energy use increases this measure of efficiency wail decrease as the best land for wind，bibfuls，and solar power gets used up.

Solar power is much more__________ (56) than bibful in used but it would still ________(57)1 50 square kilometers terms of the area of land of photovoltaic(光电的) cells to match the energy production of the 1 000 MW nuclear plant.in another example, he says__________ (58)the 2005 US electricity demand via wind need 780，000 square kilometers，an area the__________(59)of Texas power alone would However，several experts are highly critical of Amusable’ s________(60).John Turner of the US government’s National Renewable Energy Laboratory says that even if the US got all of its_______ (61) from solar energy, it would still need less than half the amount of land that has been _________(62) highways.Further，it need not ________(63)up additional land. The US could get a quarter of its energy just from covering rooftops of existing buildings，he says According to Turner，the same“dual use”also_________(64) to wind power. footprint for wind is only 5%of the land that it ___________(65) . Farmers can still farm the land that the turbines are on.Turner says looking solely at land use is an 0versimDlificatiOn of the issue.
