【答案】（1）Problems（2）How
     April 22nd is World Earth Day and we all know it is important to love our Mother Earth.There is no doubt that protecting the environment is still worth people's attention in the new century.Many factories pour waste water into rivers.Someone throws rubbish everywhere.They leave the lights on when they leave the room.
   As teenagers，we are supposed to play an important role in protecting the environment.First，we should  pick up the rubbish on the ground.Second，we had better ride a bike or take the subway to school.Third，we should remember to stop using plastic bags and use cloth bags.
   I'm sure everybody is able to do something meaningful to make the world better.
