Water is very important to living things. Without water there can be no life on the earth. All animals and plants need water. Man also needs water. We need water to drink, to cook our food and to clean ourselves. Water is needed in offices, factories and schools. Water is needed everywhere.

There is water in seas, rivers and lakes. Water is found almost everywhere. Even in the desert part of the world, there is some water in the air. You can not see or feel it when it is a part of the air. The water in the seas, rivers and lakes is a liquid, the water in the air is a gas, and we call it water vapour (蒸气).

Clouds are made of water. They may be made of very small drops of water. They may also be made of snow crystals(结晶体). Snow crystals are very very small crystals of ice. Ice is frozen water. It is a solid. There can be snow and ice everywhere in winter.

Water may be a solid or a liquid or a gas. When it is a solid, it may be as hard as a stone. When it is a liquid, you can drink it. When it is a gas, you can not see or feel it.

When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farmstead, in the winter especially, we wear quite out off from the outside world. As soon as I left school, I packed my bags and moved to the capital. However, I soon discovered that city life has its problems too.

One big disadvantage is money. It costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma（哮喘）, and at times the air is so dirty that I am afraid to go outside. Then there is the problem of traveling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.

Of course there are advantages. First, there is so much to do in the city, whatever your tastes in culture or entertainment. Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising - and, what is more, shops are often only a short walk away.

Is life better then, in the city? Perhaps it is, when you are in your teens or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem preferable. I certainly hope to move back there soon.
