Dear classmates,

　　 How are you? Today is June 8th. I will tell you about a bike accident and warn you not to ride a bike too quickly.

　　 Yesterday morning, we walked to Hebin Park. At 7:10 a.m. on Hexi Road, a young girl with yellow hair was riding very fast, answering the cellphone when she was past us. Then a Taxi came from the opposite fast. The bike hit the Taxi. The girl fell off the bike and her right arm was broken. We rushed there and helped the Taxi driver call 122 hotline and sent the young girl to the hospital. We will never forget this terrible accident. Do you obey traffic rules? That’s all. Thank you.
