One possible version：
Good morning, ladies and gentlemen,
With the improvement of the living standard, there has been a tendency that people begin to turn to motorcycle.
However ，in my opinion ，we should encourage people to keep on riding bicycles。
Firstly ，bicycles cause little pollution to the environment 。since a bicycle is much quieter than motorcycle ，it doesn’t cause noise pollution。Moreover ，a bicycle never sends out harmful gas into the air 。secondly，either in the process of making bicycles or using them ，they consume much less energy than motorcycles。Thirdly，riding bicycles does good to our health。It is an effective method available to do physical training 。riding bicycles can build our body and keep us fit。
Due to the reasons mentioned above ，it can be concluded that riding bicycles is really good for the individual as well as the whole society。
So why not call for riding bicycles and enjoy a low-carbon life?
Thank you !
