Most of the world’s energy comes from the sun. The sun’s energy is in wood, oil, and other things that people use for energy.
VI. Read the text then answer true or false
People use many sources of energy. Ancient people used only their arms, hands, and simple tools until they discovered fire. Later, people learned to use the energy of the wind to sail ships. Then they learned to use animals to do work. In the eighteenth and nineteenth centuries, people began to use machines. The first machines used steam. They burned coal to heat water. The hot water turned into steam, and the steam engine did the work. Later, people began to use the gasoline engine, and today people are using nuclear energy. Energy is one of the basic concepts, or ideas, of physics. It is the ability to do work. Without energy we could live. We need energy to work, and scientists are always looking for new sources of energy.
1. None of the world’s energy comes from the sun. F
2. Wind, steam, and gasoline are sources of energy. T
3. People have never used nuclear energy. F
4. Energy is the ability to do work. T
5. We need new sources of energy. T

Read the passage then answer the following questions:
"I will think of it."It is easy to say this; but do you know what great things have come from thinking? We can not see our thouhts, or hear, or taste, or feel them;and yet what mighty power they have! Sir Isac Newton was seated in his garden on a summer's evning, when he saw an appe fall from a tree. He began to think, and, in trying to find out why the apple fell, discoveed how the earth, sun, moon, and stars are kept in their places. A boy named James Watt sat quitly by the firside, watching the lid of the tea kette as it moved up and down. He began to think; he wanted to find out why the steam in the kettle moved the heavy lid. From that time he went on thinking and thinking; and when he became a man, he improved the steam engine so much that it could, with the greatest ease, do the work of many horses. When you see a steamboat, a steam mill, or alocomotive, remember that it would never have been built if it had not been for the hard thinking of someone. A man named Galileo was once standing in the cathedral of Pisa, when he saw a chandelier swaying to and fro. This set him thinking, and it led to the invention of thependulum. James Ferguson was a poor Scotch shepherd boy. Once, seeing the inside of a watch, he was filled with wonder. "Why should I not make a watch?" thought he. But how was he to get the materials out of which to make the wheels and the mainspring? He soon found how to get them: he made the mainspring out of a piece of whalebone. He then made a wooden clock which kept good time. He began, also, to copy pictures with a pen, and portraits with oil colors. In a few years, while still a small boy, he earned money enough to support his father. When he became a man, he went to London to live. Some of the wisest men in England, and the king himself, used to attend his lectures. His motto was, "I will think of it;" and he made his thoughts useful to himself and the world.When you have a difficult lesson to learn, don't feel discouraged, and ask someone to help you before helping yourselves.Think, and by thinking you will learn how to think to some purpose.
