Task 2. Listen to the speakers twice and say True or False.
And transcript for listening task can be found after the rubrics.
Topic "Nature"
People usually say that nature is our mother. It gives a person everything that is necessary for life, even though we don't always appreciate its gifts. What could be better than the warm sun, majestic mountains, and blooming trees in the spring? The world of nature is very rich and varied. There are hundreds of thousands of species, many of which we've never seen in our life.
We all used to live in a world that seems to be built by ourselves. We live in big houses equipped with high-tech consumer devices; we can travel long distances using cars, trains, and planes. We are able to know what is happening thousands of miles away, using the Internet or television. We use the knowledge of the laws of nature and its power to create all these technologies anyway.
Certainly, you cannot live fully if you do not have the opportunity to bask in the summer sun, enjoy the fresh morning air, breathe the scent of roses, see billions of stars high in the night sky. People like to spend their weekend and holidays outdoors so that communication with nature helps them to relax and gather strength to solve important problems in our "human" world.
It is very frustrating that people are fascinated by the development of new technologies that often damage the nature. Our activity is cause of the pollution of the environment, climate changes, extinction of animals and plants. Years ago, it was not very noticeable, but now the people in the big cities cannot breathe.
