When Susan White went back to high school a couple of years ago, she never had any thought about actually getting a high school diploma.
“I just wanted to learn more,” she said. But when she found out that many of her classmates were planning to graduate, Mrs. White recalled(回顾), “I said my young friends can graduate from high school, so can I.”
She seems to have been right. As soon as she finishes a history course, Mrs. White will graduate next month. And when she does, she will enter the record books as the oldest person ever to graduate from high school in the United States.
Mrs. White is 98 years old and nobody has finished high school at an older age.
Mrs. White dropped out of school(退学) in the 10th grade, but her ability to learn has clearly not been reduced after she left school for 80 years. Since going back to her studies, she has kept up a straight record that is the highest possible.
Now that she is about to get a diploma, Mrs. White has become a strong believer in getting a good education.
“I don’t like anyone dropping out of school,” she said. “It makes me mad when a person decides to leave school, because future generations(后代) will have to know even more than we do in order to survive(生存)”.Mrs. White sets a good example of lifelong study!

We have always been interested in the moon.2000 years ago, people already knew that the moon moves around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky.
When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on the earth. This was because they believed the moon had once been a planet that had been caught in the earth’s gravity millions of years earlier.
In 1969, moon rocks werefinally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once part of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars hit the earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.
In the future, even thought our ideas about the moon may change again, we will still be interested in it.

New Energy in the Twenty-first Century Energy from the wind.
All over the world, people use the power of the wind. It is a clean source of energy, and there is lots of it. But if the wind does not blow, there is no wind energy.
Energy from the water
When water moves from a high place to a lower place it has the power to make electricity. In Britain, waterpower produces enough energy to power a town with 40000 people. Waterpower gives energy without pollution, but people have to build dams(大坝) to use this kind of power, and building dams is very expensive.
Energy from the earth
There is heat in the rocks under the earth. Scientists use the heat to make geothermal(地热的) San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is only possible in a few places in the world.
Energy from the sun
Solar panels(镶板) on the roofs of houses and buildings can turn energy from the sun into electricity. These panels can create enough energy to heat the whole house during winter. Solar power is clean and plentiful, but when the weather is bad, it can’t produce power.
