题目内容
14.Thirty years ago,Lake Ponkapog in Hartwell,New Jersey,was full of life.Many birds and animals lived beside the water,which was full of fish.Now there are few birds,animals and fish.The lake water is polluted.It is in a color of dirty brown,and it is filled with strange plants.How does this happen?First we must think about how water gets into Lake Ponkapog.When it rains,water comes into the lake from all around.In the past,there were forests all around Lake Ponkapog so the rainwater was clean.
Now there are many homes around the lake.People often use chemicals (化学品) in their gardens and inside their houses for cleaning or killing insects (昆虫).There are also many businesses.Businesses use chemicals in their machines or shops.When it rains,the rainwater picks up all the chemicals from homes and businesses and then carries them into the lake.They pollute the water and kill the animals.
Boats on the lake are also a problem.Lake Ponkapog is a popular place for motorboats.But oil and gas from boats often get into the lake.So more bad chemicals go into the water this way.
People in Hartwell are worried.They love their lake and want to save it.Will it possible?A clean lake must have clean rainwater going into it.Clean rainwater is possible only if people are more careful about chemicals at home and at work.They must also be more careful about gas and oil and other chemicals on the ground.And they mustn't use motorboats any more on the lake.All these may change people's lives.Only then can Lake Ponkapog be a beautiful,clean lake again.
