UNIT 5. TIME FOR DISCOVERY » Стр.207 (4)

I have learnt that the Earth is a round ball with a land, seas, oceans, continents and even countries. I have learnt that all the countries have interesting people, places, animals and plants. I have learnt that people of different nationalities live in these countries. I have learnt that they speak different languages. I have understood that each country has its national flag, anthem and its own traditions and customs. I have thought that discoveries are riot useful but now I know that they help us to learn many interesting things about the planet we live on.
