Answer 1

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_motorcycles.
     However,in my opinion,we should encourage people to keep on riding bicycles.
     Finally,bicycles cause little pollution to the environment.Since a bicycle is much quieter than a
motorcycle,it doesn't cause noise pollution. However a bicycle never sends out harmful gas into the air.
Secondly,either in the process of making bicycle or using them,they consume much less energy than
motorcycles.Thirdly,riding bicycles does good to our health.It is an economical and 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 an
individual as well as the whole society.
     So_why_not_call_for_riding_bicycles_and_enjoy_a_low－carbon_life?
