     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 (用推土机推平) 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 (别遗忘) was the drought (旱灾) 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 roller-skated 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 park tress, and pretty soon

the trees started dying, too. Next, the park 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.

     As the drought lasted into the fall, the park got worse every month. The rubbish piled up or blew across the

brown grass. Soon the only people in the park were beggars and other people down on their luck. People said

drugs were being sold or traded there now. The park had gotten scary, and my mother told us kids not to go

there anymore. The drought finally ended and things seemed to get back to normal, that is, everything but the

park. It had gotten into such bad shape that the city just let it stay that way. Then about six months ago I heard

that the city was going to "redevelop" certain worn-out areas of the city. It turned out that the city had planned

to get rid of the park, sell the land and let someone build rows of apartment buildings on it.

     The chain-link fencing and the bulldozers did their work. Now we live across the street from six rows of

apartment buildings. Each of them is three units high and stretches a block in each direction. The neighborhood

has changed without the park. The streets I used to play in are jammed with cars now. Things will never be the

same again. Sometimes I wonder, though, what changes another drought would make in the way things

are today.
