Good morning, everyone,
  I am Li Hua from Xingguang Middle School. The topic of my speech is “Let’s Ride Bicycle”.
  At present, our country develops so fast. But it is at this time that so many social problems coming into being. For instance, so many cars drived on the road make the air be polluted and the traffic is always crowded. This kind of problem makes our life so uncomfortable and unconvient. Everybody believes cars provide us with a better life, but in fact,they make worse. So why not change the way like riding bicycles. At least, a bicycle is much cheaper than a car. It will lead you into a low-carbon life, and help you become more healthy. It's also an energy-saving transportation, you don't need worrying about the price of petrol.
  In a word, let's ride bicycles and make the change.
  Thanks !
