Boys and girls，the topic of my lecture is to go to school in an environmentally friendly way.As we all know，automobile exhaust gases are considered one of the major sources which are poisoning the air badly.Then can we do something to make a difference？Of course we can.At least we can choose an environmentally friendly way to go to school every day.That is to say we should avoid taking a private car.Instead we should choose public transport as much as we can.If possible，we can ride a bike or take a bus to school.Not only can we save some money，but also build up our body by riding a bike every day.If every one of us follows the suggestion above，we are going to contribute a lot to the environment protection.名师点睛
