We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas.

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.

II. Read the following passage carefully, then do as directed : (5 marks)
Thinking about how we will be travelling in 10 or 20 years is very interesting. Will we still be using planes or will we be flying our cars from Paris to London? Here are some suggestions.
- SkyTrain: Currently being developed at NASA, SkyTrain looks like the monorail at Disney World. Moving at 240km/h and using small amount of energy, it could be the future of city transportation. SkyTrain has the passenger capacity of a 6-lane highway.
- Flying cars: Zhu Wenxi and Lai Zexin, Chinese students, have designed a solar-powered flying car that doesn’t need a runway to take off. If you have about 200 hundred thousand dollars, you will own this vehicle soon.
- An electric mininus: The minibus Cameo, designed by Martin Pes, can carry 32 passengers but it is small enough to get its way out of a traffic jam. Its electric motor and low weight mean that it can be recharged in seconds while stopping and it has zero emission.
- An eco-taxi: Taxis are bad for the environment and traffic jams. We enter eco-taxi, and individual taxis form a train powered by solar panels.
1. Decide whether the statements below are True (T) or False (F) : (2,5 marks)
a. SkyTrain is fast but cannot be used as a means of transport in the city. …………
b. Flying cars designed by Zhu Wenxi and Lai Zexin run on solar energy. …………
c. A long runway is necessary for flying cars to take off. …………
d. Because it is small, an electric minibus can avoid traffic jams. …………
e. Several eco-taxis can form a line moving together, using solar energy. …………
2. Answer the following sentences: (2,5 marks)
a. How fast can SkyTrain travel?
………………………………….............................................................................................
b. Where are the designers of flying cars from?
……………………………………………………………………………………………………………….
c. How much money does a flying car cost?
……………………………………………………………………………………………………………….
d. Why should we take eco-taxi instead of other taxis?
……………………………………………………………………………………………………………….
e. Are you interested in these means of transport? Why?

For example, an apple has about 80 calories, while a 1.6 km walk might use up 100 calories. Calories are important for human health, and the key is having the right amount of it.

B. Everyone needs different amounts of energy per day depending on age, size and activity levels. An athlete needs more calories than an office worker. To stay in shape, an average adult requires at least 1,800 calories per day (according to the Food and Agriculture Organization of the United Nations). If we eat just the number of calories our body needs each day, we will probably be healthy. However, eating too much can make you put on weight. To lose weight, eat fewer calories than your body burns each day.

C. These are some experts' tips to reduce calorie intake. First, you must know how many calories you need each day and always count them in your diet. Have small frequent meals and drink more water too. This will help you feel less hungry. Furthermore, avoid all sugary drinks and junk food. They are high in energy but low in nutritional value.

What are calories?

A. They are units of energy.

B. They are the amount of energy.

C. They are important.

D. Each person needs different amounts of calories.
