Lesson 2

1.Прочитайте и переведите текст. Water is life.

Water constitutes 70% of the weight of human body. It’s as necessary to a man as air? Which he breathes, and even more essential to his life than food.

We can live without food for several weeks but we must die in a few days if we have no water to drink.

Water is everywhere. It is one of the most widely spread and important substances known to us. The clouds are nothing but little drops of water. The air we breathe contains water in the form of invisible vapour. Without water there would be neither animal nor vegetable life. The soil under normal conditions contains water, which as we all know is necessary for the growth of plant. The plants themselves contain large quantities of water, in fact, most of the vegetables we use contain much water. Some of them, such as cucumbers and tomatoes contain as much as 95% of water. Milk is about 87% water.

Water is life. All the life on earth depends on water.

Water passes through very interesting natural cycle. The atmosphere, which surrounds the surface of the Earth contains water. It varies in amount in direct proportion to the temperature of it’s gases. Water is also evaporated into atmosphere. Atmosphere, which has become saturated with water, precipitates it’s moisture when the temperature lowers.

This phenomenon is termed rainfall.

The moisture falls to the earth and find it’s way into a number of reservoirs, provided by nature.

From the water surfaces of the earth the sun is constantly evaporating enormous volumes of water. Then they are condensed and precipitated upon the land and water surfaces as rain show or ice. Some of water is evaporated again; some is absorbed by growing vegetation; some flows directly over the ground into the rivers and lakes; some sinks into the soil to become the subterranean water of the earth.

As the descending rain or snow approaches the earth, it washes out of the atmosphere suspended particles of dust and thus purifies the air.
