    On a hot September afternoon，Peter and his friend Isabel were on their way to the library.When they passed by Tubman park，Isabel suggested cutting through it to get to the library.As they entered the park，the sight of the swings and the merry-go-round （旋轉(zhuǎn)木馬） brought back a flood of memories of their childhood spent there.But now everything looked so old，sad，and dirty.Litter lay on the ground next to an overflowing trash bin.There were still young schoolchildren playing there but they had to avoid the trash that littered the playground.A little boy told them that the city took the other trash cans away and the remaining one never got emptied often.
    As they headed toward the library，the two high school students wrinkled their forehead （皺起了眉）.In the library，they met Mrs.Evans，their kindhearted fifth grade teacher，retired yet still passionate.Mrs.Evans listened as Isabel and Peter eagerly explained what they'd seen.Finally，she recommended them to go to the Go Green，a nonprofit organization whose goal is to protect the environment，for help. "This group is good at raising money for projects just like yours，" said Mrs.Evans.She promised to present their ideas to Go Green.Hearing this，their face lit up.
    Two main tasks remained ahead：researching ways to clean up the park and preparing a convincing （令人信服的） speech.As Isabel was good at researching while Peter always had a talent for speaking，they worked together quite well.Isabel learned from a science magazine that a new type of trash bin can squeeze （ 壓 ） the trash down without being emptied often，which saves time，money，and energy.Based on this，Peter practiced his speech over and over again.
