Проверьте грамотность!

1. Is art important for us nowadays?

In the modern society some people recognize that art is very important. Others don’t think so.

On the one hand works of art make our life more interesting, more fascinating, because artists give feelings, emotions, experience with the help of their music, paintings, sculptures. Moreover art develops our spiritual life. Without art people become pour inside.

On the other hand I know some people saying art is useless and boring. They say it’s waste of time to go to the theatres, galleries and listen to symphonies. They prefer others kinds of activity. Moreover some people don’t understand impressionists, surrealists and others schools of art. They think such works of art affect the mind and the psyche of people.

To sum up there is no agreement about the role of art in our life.

Personally I think art is very important in our life. Each respectable person should know about famous composers, painters, architects, sculptors. And he should love and respect art.

 

2. Why is pollution a big problem for people now?

Nowadays the situation in our environment is very difficult and dangerous. A lot of wastes from factories, electric power stations, chemical industry, and heavy industry go into the air, soil and water.

The water in rivers has become polluted in many places. If people drink this water they can get ill and even die. Fish in such rivers become toxic and dangerous to eat. A lot of trees on the banks die.

On the other hand some people don’t think it’s a big problem. In fact, we can’t close all factories and prohibit using ships in the rivers. Moreover it’s impossible to look after all people pouring domestic waste into rivers.

 In any case people must do everything possible to keep the rivers clean.

In my opinion it’s very important to save the water for ourselves and for next generations. We should be nature’s best friends and take care of it.
