生命的产生

by Hendrik Willem Van Loon Man was the last to

come but the first to use his brain for the purpose of conquering the forces of nature. That is the reason why we are going to study him, rather than cats or dogs or horses or any of the other animals, who, all in their own way, have a very interesting historical develop ment behind them.

In the beginning, the planet upon which we live

后来有一天伟大的奇迹出现了。原来死气沉沉的一切

产生出了生命。
