　　There is a lake near a forest in Sweden. The water in the lake is very clear and everything is quiet and still. On the far side of the water is some farmland and further away, across the field, is an old church built on a hill. It is spring time and it has just stopped raining. The stream flowing into the lake is full and there is still some half-melted snow from last winter on the ground.

　　The reason why the water is so clear, and everything is so quiet and still, is that most of the plant and animal life in and around the lake is dead. There are no birds because all the fish and insects(昆虫), which the birds need for food, have disappeared. Many trees in the forest are losing their leaves and bark, and are sick and dying. Others were blown down by the high winds of last winter. A farmer is working in a field planting wheat, but unless he plants a stronger kind of seed this year, the crop will be between 25 to 40 percent lower than a few years ago. The stone of the old church is turning to powder and unless the tower is repaired soon, it will fall down.

　　All the death and destruction in this place is due to(由于) pollution : pollution from smoke coming out of factory chimney and fumes(烟) coming out of the exhausts(排气) of cars and trucks. And yet this silent lake is hundreds of kilometres away from the nearest factory and motor way.

Why should we learn to swim?
Firstly, swimming is a good exercise for our health. Indeed doctors say it is the best exercise, because in swimming all the muscles of the body are used.
Secondly, swimming gives great pleasure. How nice it is, on a hot dusty day in summer, to take off one’s clothes and dive into the cool water of a rive or the sea, and to swim and float until one feels enough.
Thirdly, swimming may sometimes mean all the different between life and death, we never know when we may be in danger from water. We got on a voyage, and the ship in wrecked; we go for a pleasure sail on a lake and the boat turns over; we slip as we are walking along the bank of a river, and half in the water. If we can swim, we have chance for saving our own lives, but if we cannot swim, we are pretty certain to be drowned. So for our own safety, we should learn to swim.
Lastly, if we can swim, we may be able to save other people from drowning. How sad it is to see a friend drowning before our eyes while we cannot help just because we cannot swim.
