The first major energy transition was from wood to coal. For many centuries people used wood as a primary source of energy. By burning wood people were able to heat their homes, cook their food, and produce basic items. Most early societies grew up near a sufficient supply of wood. The main advantage of wood was that it was easy to get and easy to bum. During the early 1800's, some towns and villages began to make a transition from wood to coal as a basic source of energy, because they found that coal generally burns longer and at a higher temperature than wood, and a long-burning and hot-burning fuel was badly needed for the machines that were being used at that time. Another advantage of coal was that there was a lot of it and it was also easy to get. Besides, it could be easily shipped to faraway places. As a result of the transition from wood to coal, industry developed very rapidly. People were able to get more things and their standard of living went up. The second major energy transition was from coal to oil. We'll discuss it next week. Why did most early societies grow up near a sufficient supply of wood？ A．Because wood was safer than coal. B．Because wood burned longer than coal. C．Because there was more wood than coal. D．Because they used wood as primary source energy.

In passive sleep the body is at rest. We move very little. And the brain becomes very inactive, ff a person continues to sleep, she or he enters anew period, a more active period. The body goes through several changes: the brain temperature rises, blood in the brain increases, the body becomes very still and the brain goes into active state. And as the brain goes active, the eyes begin to move rapidly. And that is the sign of another change---the person is dreaming. Throughout the night, people alternate between passive and active sleep. Doctors have studied the sleep cycle and have found that everyone dreams---in fact, that everyone needs to dream in order to stay healthy. It appears we need both kind of sleep.
