But now our environment has become worse and worse. So how can we help to protect it? Here are some ways. First, we should go to school on foot or by bike and tell our parents to take buses to work instead of driving cars. It not only can protect the environment，but also is good for our health. Second, we are supposed to sort the rubbish into different kinds because some can be reused or recycled. Third, to save water and electricity, it is important to turn off the taps, fans, TV sets and lights in time when we don’t need them. What's more, stop littering! It's necessary to put things you don't need in the bins. There's a lot for us to do. I think if everyone does something，our environment will become better and better.  Show Time Which is the best?
