Good morning, everyone,
I am Li Hua form Xingguang Middle School. The topic of my speech is "Let's Ride Bicycles".
As is known to all, with the improvement of people’s living standards, cars have become a popular means of transport, bringing great convenience to our life. However, they have also caused some problems such as air pollution and traffic jams.
How can we solve the problems then? As far as I’m concerned, riding bicycles is a good solution. For one thing, bicycles don’t need any petrol and they are energy – saving. For another, bicycles are environmentally friendly because they won’t give off waste gas. What’s more, riding bicycles is a good way for us to exercise and it is beneficial to our health.
Therefore, let’s take the responsibility to build up a low carbon city by riding bicycles. Come on and join us!
Thank you!
