I used to live in a small town with trees all around. There was no tall building and the only street was narrow. Just outside the town， there was a river. You can see different kinds of fish swimming in the clear water. People here lived a simple life.
Great changes have taken place here. You can see tall buildings， big department stores and factories everywhere. Different kinds of cars and buses are running in the big streets. But with the development of the industry， we have fewer trees. Air and water pollution is becoming more and more serious. We must do something to stop pollution and make our town even more beautiful.
我過去住在一個小鎮周圍有樹木。沒有高樓,只有街道很窄。就在城外,有一條河。你可以看到不同種類的魚在清澈的水裡游泳。這裡的人們過著簡單的生活。
這裡發生了巨大的變化。你可以看到高樓大廈,大百貨商店和工廠無處不在。不同種類的汽車和公共汽車是運行在大的街道。但隨著行業的發展,我們有更少的樹。空氣和水的污染越來越嚴重。我們必須做些事情來阻止污染,使我們的城市更加美麗。
