Ex3:

I  live on  the outskirts of a  city  in Viet Nam. Three years ago, my neighborhood was very  clean and beautiful,  with  paddy  fields  and  green  trees.  However,  in  the  last  two  years,  some  factories  have appeared in my neighborhood. They have caused serious water pollution by dumping industrial waste into  the  lake.  The  polluted  water  has  led  to  the  dead  of  aquatic  animals  and  plants.  Also,  tall residential buildings have replaced the paddy fields. More people result in more cars and motorcycles. Poisonous fumes from these vehicle are serious air pollutants.
