【答案】Recently，Guangzhou is trying to build itself into one of the national civilized cities.Everyone is trying to make a contribution to it.As students，we should also do something to help.Here are some suggestions.
First of all，we should be polite and  civilized students.We need to be friendly to people around us.Besides，it's important to keep the environment clean.Stop throwing rubbish everywhere.What's more，we should obey the traffic rules.Don't cross the road until the traffic light yurns green.We can also try to help people in need by doing some voluntary work in our spare time.Last but not least，remember to wait in line when we wait for the bus or underground .
If everyone tries their best，I'm sure we will make Guangzhou a civilized city.
