The slogan by the pond

The sign on the edge of the flower bed-"The flowers are smiling, please go around!" "Flowers are angels, please protect them!" "The flowers are blooming, please don't pick them!" The sign on the lawn-"The grass is growing, please cherish it". "Don't trample on the grass." "The grass is reluctant, and everyone cherishes it." "It's a pity to step on the green grass." Even Ping Li, a student who has a headache in writing, wrote such a poetic sentence as "Leave flowers and plants to add color to life". "The grass is sleeping, please don't disturb it." "The grass is green, how can you stand it?" The sign by the pool-"The water is unpredictable, please don't swim." "Protecting water resources is everyone's responsibility." "Water is the source of life, please cherish every drop of water." Please don't destroy the fish's home. The sign next to the light switch-"I care about me at dark and you care about me at dawn." "Come and go in a hurry, don't forget to turn off the lights." Please save every kilowatt hour! "Please don't make me blink!"
