Good morning , everyone ,
I’m Li Hua from Xing Guang Middle school . The topic of my speech is “Let’s ride bicycle” .
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 am 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!
