After yesterday's test of unit 1, we began unit 2 today. A new chapter, a new feeling. Today's class, we talked about the population and the settlements. We have already 7 billion people on our earth. It is an amazing number. However, there are 1.3 billion of people in China! almost the 1/5! but the area of China is just a small portion of the earth. And also, there are almost 20,000 people has born every day, that is a large number. and 140 per minute, that is so interesting. A long time ago, people used almost 10,004 years to increase 1 billion of people, however, nowadays, we just need 12 years to increase the same amount! That's crazy.
