Dear Fred,

Thank you very much for your letter. It was great to hear from you again!

You said that you'd like to come to Russia one day to practise your language skills. I think it's great! As for me, I'd like to recommend you summer for your trip because the weather is pleasant and warm.

To my mind the Red Square, the Bolshoi Theatre, the Tretyakov Gallery are worth seeing in Russia. They are very interesting and famous places.

I'd like to visit Great Britain because there are many unique and beautiful places there. I also can practise my English.

Please write me soon.

Best wishes,

Olivia

Nowadays, environmental problems are the most burning for the society. Air, water, land and nuclear pollution badly damage the nature. People cut down trees and destroy the habitat of thousands of animals. As a result, many species are in danger of extinction. Factories pollute our rivers and lakes with dangerous chemicals. The increasing number of cars in towns and cities has led to the growth of harmful gases in the atmosphere. There is much litter everywhere, our parks and forests are full of rubbish.
