my family and i lived across the street from southway park since i was four years old. then just last year they city put a chain link fence around the park and started bulldozing (用推土機推平) the trees and grass to make way for a new apartment complex. when i saw the fence and bulldozers, i asked myself, “why don’t they just leave it alone?”
looking back, i think what sentenced the part to oblivion (別遺忘) was the drought (旱災) we had about four years ago. up until then, southway park was a nice green park with plenty of trees and a public swimming pool. my friends and i rollerskated on the sidewalks, climbed the tress, and swam in the pool all the years i was growing up. the park was almost like my own yard. then the summer i was fifteen the drought came and things changed.
there had been almost no rain at all that year. the city stopped watering the park grass. within a few weeks i found myself living across the street from a huge brown desert. leaves fell off the part tress, and pretty soon the trees started dying, too. next, the part swimming pool was closed. the city cut down on the work force that kept the park, and pretty soon it just got too ugly and dirty to enjoy anymore.
