【答案】Dear fellow students，
It is known to all that our city is trying to build a national civilized city to create a better living environment for us.I am writing to call on all of you to make joint efforts towards this goal.
As students，we can do many things to help.First of all，it's important to care for the public environment and keep our school clean.
For example，we mustn't drop litter or make loud noise.Second，we are always supposed to obey the traffic rules.Third，it would be helpful to have the volunteerism and volunteer in our spare time encouraging other citizens to behave properly.More importantly，improving ourselves is a good way to make us more civilized.Dear fellow students，let's work together to make our city a better place!
Thank you!
