New Energy in the Twenty-first Century Energy from the wind.
All over the world, people use the power of the wind. It is a clean source of energy, and there is lots of it. But if the wind does not blow, there is no wind energy.
Energy from the water
When water moves from a high place to a lower place it has the power to make electricity. In Britain, waterpower produces enough energy to power a town with 40000 people. Waterpower gives energy without pollution, but people have to build dams(大坝) to use this kind of power, and building dams is very expensive.
Energy from the earth
There is heat in the rocks under the earth. Scientists use the heat to make geothermal(地热的) San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is only possible in a few places in the world.
Energy from the sun
Solar panels(镶板) on the roofs of houses and buildings can turn energy from the sun into electricity. These panels can create enough energy to heat the whole house during winter. Solar power is clean and plentiful, but when the weather is bad, it can’t produce power.

解析

试题分析：在二十一世纪的时期，我们可以利用新的能源，例如：风能、水的能源、地热和太阳能。每一个能源都有它的优点和缺点。短文通过一张图表的形式，将其优点和缺点明确的展示出来，让大家一目了然。
小题1:细节理解题。问题：风力能源的缺点是什么？联系原文：if the wind does not blow, there is no wind energy.句意：但是,如果没有风，就没有风能。明确了风能的缺点。故填：If the wind doesn’t blow, there is no wind energy.
小题2:细节理解题。问题：水力能源的优点是什么？联系原文：Waterpower gives energy without pollution.句意：水力能源没有污染。明确了优点是没有污染。故填：Without pollution.
小题3:细节理解题。问题：地热能源其优点是什么？联系原文：This kind of energy is cheap.句意：这种能源是便宜的。说明地热能源的优点。故填：Cheap.
小题4:细节理解题。问题：太阳能的缺点是什么？联系原文：when the weather is bad, it can’t produce power.句意：当天气不好的时候，它就不能产生能量。故填：It can’t produce power if the weather is bad.
