You fall at up to 150 kilometers an hour until the ropes 13 you from hitting the ground. It is said that 2 million people around the world have now tried bungee jumping.

16 do people take part in such activities as these? Some psychologists(心理学家)suggest that it is 17 life in modern societies has become safe and boring.

Everything that was 6 had to be thought 7 and built by Edison and the men 8 worked with him. There was no places where they could buy the things they needed. Edison made 9 inventions in order to send electric power to 10 it was wanted.

Madam Curie started her research that 8 to the Nobel Prize when she was 28. Einstein was 26 when he published his world-changing theory of relativity. Well, 9 of that.
