18、January is a City Park's Clean - up Month． So we need to come up with a plan to tell people about the city park's clean - up．First of all， well hand out advertisements after school．Then, we could put up signs．Next, we should each call up ten people and ask them to come．Finally，we have to set up a call - in center for school．Then everyone can call us． I hope the strategies that we came up with will work out fine．Start today．
