Besides providing a perfect environment for sea plants and animals to live in, seawater has other values, one of which is that it constantly moves, and its movements produce energy.
The most obvious movements are the waves and the tides. Winds cause the waves, and the gravitational pull of the moon and the sun causes the tides. In places like the Bay of Fundy in Canada, the difference between the high and low tide level can be as much as 40 feet.
France and Britain are now trying to use energy in the tides to produce electricity. Waves can produce electricity and some experiments are taking place to learn more about this. One of the most encouraging areas of research uses the difference between the temperature of seawater at the surface and deep down to produce electricity.

A．the same forces |

Ted doesn’t like cars. He wants people to stop driving because cars make the air dirty. Ted had an idea. He said,“I’m going to cycle around North America. I want to show everyone that cycling is a fun way to get around. If more people ride bikes, the air will be cleaner.”
He left his hometown with $160 in his pocket. When he got to San Diego, he met another cyclist. The cyclist invited Ted to speak at a big meeting about the environment.

Anna Mary Robertson, better known as “Grandma Moses”, turned to painting because she could no longer take an active part in the funning of her farm. As she searched for something to do, she discovered painting--- an activity she had loved as a child.
Grandma Moses painted in primitive style, and her works are simple and basic — almost childlike in their composition. She first painted only for her own pleasure, and then began to sell her works for small sums of money.
In 1939, an art collector named Louis Caldor chanced to see several of Granma Moses’ works hanging in a store. He liked them, bought them at once, and set out to look for more. Caldor held a show to introduce the works of Grandma Moses to the art world.
