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, which is cycling.
There are many good reasons to ride bicycles. First of all, compared
to cars, bicycles are much chcaper 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 !
