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
Part of my job as a conservationist is to count the number of lions in the local area. The population isn't in danger, but it's important to check the situation often in case the number of lions starts to decrease. Two of the main goals of my job are to watch for any problems that could hurt the lions and find ways to protect them from the modern world. It's sad, but all
Wild animals need our help—not just lions. When people or companies discover something they want in an area, they don't think enough about the effects on animal populations. You can't simply cut down trees in a forest, for example, without hurting the animals that live there.
Wild animals (and wild plants) and the wild places where they live are seriously threatened almost everywhere. One species has become extinct in each year of this century. But many hundreds are now in danger. Lack of attention would lead to the rapid advance of the process of extinction.
Already many kinds of wild animals have been so reduced in number that their role in the ecosystem is forgotten. Animals like the great apes, the whales, seals etc. thought to be in danger of extinction.
But even more important, perhaps than individual kinds of animals and plants, whole habitats are in danger of vanishing: marshes are being drained, and the world forests, especially tropical forests are being cut down to satisfy man’s needs of timber and paper.
What would our world be like if all the wild animals and wild plants vanished? - Would our life still exist then?
1. What would happen to the human beings if the wild life vanished?
A. Many species would quickly become extinct.
B. The human life would be seriously threatened.

D. Tropical forests would be cut down.
2. What is more important than individual kinds of animals and plants?
A. the vanishing of whole habitats. B. the extinction of many species.

3. What does the writer caution us against?
A. cutting down the tropical forests. B. hunting wild animals.
C. draining marshes. D. destroying our environment.
4. What would happen if we cut down forests?

C. both A and B are correct. D. none are correct.
5. “To threaten” in the passage means …………..
A. to pollute B. to give fear to C. to vanish D. to poison
