ПЕРЕВЕДИТЕ ПОЖАЛУЙСТА, ОЧЕНЬ СРОЧНО НУЖНО!!!! только пожалуйста без переводчика
We have just come back from a school conference in Moscow. We heard about a 10-day expedition to the Ugra National Park. This park is located beside the Zhizdra River and has many different trees and plants found in Central Russia.
We learned that most school students in Russia study Ecology and take part in conferences and events about modern ecological problems. In the school holidays, children can go to a lot of camps where they can learn to do practical things to take care of nature and help the environment.
The aim of the student's expedition was to explore the flora and fauna of their native land and learn more about practical ecology. They learned how to experience nature by using all their senses. They were able to see, hear, feel and understand nature. In spite of millions of mosquitoes, they agreed that nature is amazing and they said that it was a fantastic experience!
The students participated in volunteer work such as cleaning the springs and paths in the forest. Their adventures also taught them a lot of practical lessons about living independently in the middle of the forest. They learnt how to put up tents, make a fire, cut wood and cook on an open fire.
One of the students' favourite activities was the nightly sing-alongs around the camp-fire. They said it was a wonderful way to relax after a long day full of discoveries and adventures. The campers really enjoyed their stay at the eco-camp. In fact, nearly all of them said that they hope to go back again next year!
