The earth, according to Lyell, was not only thousands of years old; it was millions of years old. As to the common belief that

2、changes in the earths surface happen suddenly because of a single earthquake or flood, he said that this might happen once in a while, but usually these changes took place very slowly. He believed that the surface of the earth had been changing from the beginning of time. The changes, he said, were

3、caused by the long-term action of the winds and seas, and by forces such as volcanoes breaking out under the earths surface. Once in a great while he thought, a mountain might appear for the first time after an earthquake. But usually mountains would experience a slow and steady rise.A professor nam

4、ed Henslow was interested in Lyells ideas, but he did not actually believe them. Charles Darwin could not make up his mind about them.

At the end of the school year, he went toNorth Waleswith one of his teachers to examine the rock formations and to search for fossils. Fossils are the remai

6、ns of ancient living things. They are usually fixed in rocks in the earths crust. Fossils may be of animals, such as fish, insects, birds, or humans. They may be of plants from tiny leaves to huge trees. When a living creature dies, it usually decays or is eaten by animals. However, if it sinks into

But they are also a major cause of health problems and death.For more than thirty years, theAprovechoResearchCenterhas been designing cleaner, low-cost cooking stoves. Dean Still is

13、the director of the group and he points out that every year more than one million and five hundred thousand people die from breathing smoke from solid fuels. “And half of the people use wood for cooking. These are the poorer people, and the richer people use oil and gas. Its estimated that wood is r

And so its very important for the poorer people to have very efficient stoves that protect their forests and their health,” he says.Every year Aprovecho holds a “stove camp” at its testing station. Engineers, inventors and others come together to design and

15、test different methods and materials for improving stoves. Over the years, the group has made stoves using mud, bricks, sheet metal, etc, most of which look like large, deep cooking pots and have an opening at the bottom for the fire and a place on top to put a pot.In the late nineteen seventies, Aprovecho produced a popular stove called the Lorena. The Lorena was very good at reducing smoke a
