五、阅读理解。
There is a great need to search for clean and renewable(可再生的)energy to meet our needs. It seems that wind energy is a good choice. Do you know anything about wind energy
The first advantage of wind energy is that it is truly a renewable resource. No matter how much wind we use to produce electricity,we will never reduce the supply(供应) of wind.This is its greatest advantage compared with non-renewable resources like coal or oil.Second, wind energy is a clean source of energy, which means it produces environmentally friendly electricity. What's more, the large towers, which provide the base for the wind turbines(涡轮机)，don't take up lots of space. They can share land with farms.
However, each coin has two sides. That is to say, wind energy does have some disadvantages. Wind does not provide the supply of energy without stopping. Even the windiest places on earth have periods of calm. If there isn't a strong wind, wind turbines are not able to produce electricity. The large blades of wind turbines can be very dangerous for birds and bats. The turbines cause noise pollution. It can also be bad for people living around.
Although wind energy has disadvantages,its advantages shouldn't be forgotten.
