Read the passage and check (ü) whether the following statements are true (T) or false (F).
Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favourite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. People have learned how to change energy from one from one form to another so that we can do work more easily and live more comfortably.
All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups – renewable and nonrenewable. Renewable energy source is an energy source that can be replenished in a short period of time. Nonrenewable energy source is an energy source that we are using up and cannot recreate in a short period of time.
Renewable energy sources include solar energy, which comes from the Sun and can be turned into electricity and heat. Wind, geothermal energy from inside the Earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.
However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels – oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.
Question: Renewable energy can be turned into electricity and heat.
A. True
B. False

Choose the correct answer – A,B,C or D – to each question
Mankind is feeling greater pressure from the expanding number of people. The area of the earth can never be expanded. Nor are there endless sources of food and clothing. Yet people are being born faster than they are dying. In the next forty years, the world population may double. How can so many people be fed? What is worse, there is danger that someday mankind will have only standing room.
Birth control should be a basic policy in our country. China has the greatest number of population in the world. With a high birth rate, the production of grains and goods will be unable to meet the need of the people. To raise people’s living standard, we must practise birth control.
There are disadvantages of a family having more children. First, parents cannot give their children a good breeding in food, clothing and shelter, let alone education. Second, child-rearing will exhaust the parents, leaving no time and energy for their work. Last, a family with more children will increase the burden of society.
Mankind is feeling greater pressure from........................
A. the supplying of food and clothing
B. the expanding number of people.
C. the building of remote regions
D. the expanding the area of the earth.
