Read the passage below and choose the best answers.

Each nation has many good people who take care of others. For example, some of high school and college students in the United States often spend many hours as volunteers in hospitals, orphanages or home for the elderly. They read books to the people in these places, or they just visit them and play games with them or listen to their problems. Other young volunteers go and work in the homes of people who are sick or old. They paint, clean up, or repair their houses, or the shopping or mow their lawns. For boys who no longer have fathers there is an organization called Big Brothers. College students and other men take these boys to baseball games or on fishing trips and help them to get to know things that boys usually learn from their fathers. Each city has a number of clubs where boys and girls can go and play games or learn crafts. Some of these clubs show movies or organize short trips to the mountains, the beaches, museums or other places of interest. Most of these clubs use a lot of high school and college students as volunteers because they are young enough to understand the problems of younger boys and girls.

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
