Good morning, everyone,

     I am Li Hua from Xingguang Middle School. The topic of my speech is "Let's Ride Bicycles". As is

known to us, air pollution and heavy urban traffic are becoming increasingly severe mainly due to the

overuse of cars. Therefore, it's high time we chose another better means of transport, that is, cycling.

     There are many good reasons to ride bicycles. First of all, compared to cars, bicycles are much

cheaper to buy and maintain, and you don't have all the added costs of fuel, and parking. What's more,

bicycles are more environmentally friendly than cars, because they hardly make noises and exhaust.

Cycling has become a new trend around the world, a good way of energy saving and low-carbon life.

Last but not least, cycling is an excellent way to keep fit and live longer. By riding bicycles, you can cut

down your risk of heart attacks, high blood pressure and other illnesses. So I think, riding bicycles

actually has great effects on us. Let's ride bicycles from today on!

     Thank you for listening!
