【考点】日常生活．

【答案】Having created the civilized city，all the people in Wuhan have made joint efforts.As middle school students，what should we do？
First of all，it's important and necessary to help protect the environment．For example，we shouldn't spit or throw litter here and there．We 'd better not use the plastic bags when shopping．We should grow flowers ，grass and trees.Secondly，we must follow the traffic rules．We mustn't cross the streets when the traffic lights are red．When we cross zebra-crossing，stop and look right and left，then go across the road fast.When we go out，we should walk，take a bus or ride a bike instead of driving a car.Thirdly，we should take part in voluntary activities to help the old men.Fourthly，in public places，we should offer our seats to those in need.Finally，we should be polite to others．We should be honest and behave well as well．
 I strongly believe that we will make Wuhan  a more civilized and beautiful city with our joint efforts.It's time to take action.
