Coal, oil and natural gas are examples of fossil fuels.Fossil fuels come from plants and animals that lived millions of years ago. Burning fossil fuels to create energy pollutes the air and water. Many scientists think that burning fossil fuels also increases the temperature of the earth. To reduce the use of fossil fuels. scientists are experimenting with hydrogen-powered cars. These cars don't pollute the air like gas-powered cars. Some scientists guess that by 2025, fossil fuels will run out.When people can no longer use gasoline, they may use fuel cells instead. Fuel cells use hydrogen to create energy. People do not need to worry about hydrogen running out, because it is renewable and replaceable. In Washington, D.C., a few people drive cars that run on fuel cells. When these cars need more energy, drivers can go to a hydrogen pump.The first hydrogen pump for the public opened in November 2004, marking an important step toward a cleaner environment.

Read the following article and answer the question. Article: Once a small boy lived on a farm which seemed so far away from everywhere. He needed to get up before the sun rose every morning to help his father on the farm. After an hour he could take a break for a while. Then he climbed up on the walls along the side of the farm. He could see a house with gold windows. "If they could afford gold windows, then there must be other nice things inside the house." He imagined how great it would be to live there. Then he promised himself, "Some day I will go there and see this wonderful place." One morning, his father would go to the town and told him to stay at home for a rest. Knowing that this was his chance, he took a sandwich and went across the field towards the house with the gold windows. As the afternoon went on, he began to realize how wrong he was. The house was much farther than he had expected. As he went near the house, he saw no gold windows but instead a place in need of painting. A small girl very close to his age came out of the poor house and stood there. He asked her if she had seen the house with the gold windows. The girl said, "Sure, I know." and invited him to sit on the porch . As he sat there, he looked back from where he just came. There he saw the sunset turned the windows of his house to gold! Now he understood that everyone had his own house with gold windows. Question: During his break every morning, the small boy would _ . Answer:

Read the following article and answer the question. Article: What do you call a school with no tests, no grades, no classes, and no teachers? Students of the Met School and their parents think it to be the best school in the world. The school is in Rhode Island, USA. Dennis Littky opened it in 1996. He was fired from two other schools, because many parents of the school students were happy with his unusual ideas. The school takes poor kids who are failing at schools. Nearly everybody has already given up these students and their parents want to try anything. The Met School gives Littky a great place to try out his new ideas. "The word that most kids use when they talk about high school is 'boring'," says Littky. "But no one would say the Met was boring." Advisors (not teachers) work with small groups of students for four years. Students spend almost half of their school time learning real-life skills , such as working for business , spending time with government people, and helping teach younger children. Instead of tests, the students give shows about their work outside school. In fact, students work harder here than in other schools. All the students from the Met graduate and can choose to go to a good university . Now, Bill Gates is starting schools like this one around the USA. Question: What do most high school students think of normal school? Answer:
OPTIONS:
- Interesting.
- Relax.
