六 阅读绿色能源相关短文，完成任务。
Fossil fuels(化石燃料) make the air dirty(脏的). Also, we can't get more fossil fuels—one day they will run out. So we need to use green energy.
Green energy is clean and good for Earth, and we can always get more. Today, it gives us much electricity.
What are the main types of green energy?
Water Power: It uses moving water in rivers and big dams.
Wind Power: It's not new. People used it many years ago(以前).
Solar Power: When the sun shines on solar panels, we get electricity.
Biomass: It's energy from plants around us. For example, we burn dead(枯萎的) plants to make electricity. Biomass is green energy because we plant new plants later.
New Green Energy: Oceans go up and down every day. We use this to make tide(潮汐) power. There is also heat under Earth. People can use this heat for energy. It's heat power. Maybe we will find more types of green energy.
One day, we may get all our electricity from green energy. That's good for Earth!
