Good morning, everyone,
I'm Li Hua from Xingguang Middle School. The topic of my speech is "Let's Ride Bicycle".
As is known to all, with the improvement of people's living standard, cars have become a popular means
of transport, bringing great convenience to our life. However, they have also caused some problems such as
pollution and traffic jams.
How can we solve the problem 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 don't give off waste gas. What's more, riding bicycles is a good way to exercise and it
is beneficial to out health.
Therefore, let's take the responsibility to build up a low carbon city by riding bicycles. Come on and join
us!
Thank you!
