【答案】Dear Sir/Madam，
As you can see，the road at the gate of our school is very crowded every day during and after school hours.The cars sending and picking up students not only cause traffic congestion but also potential safety problems.It is high time that we took measures.I am writing to present some of my thoughts on how to solve this problem.
On the one hand，we can tell parents to park their cars 100 or 200 meters away.Usually，it is the cars which stop or turn around at the gate that cause traffic jam.Without these vehicles，it will be less crowded.On the other hand，we can go to and from school in different periods，by doing which parents and students will not appear in large numbers.Last but not least，we should advocate low-carbon life style，and suggest the parents living close to school walk to send and pickup their children，which is beneficial to the environment as well as their own health.
Hope my ideas can be helpful.
Yours，
Li Ming
