Read the following passage and decide whether the statements are true (T) or false (F).

We use many different energy sources for the sake of us. Energy sources are classified into two groups: non-renewable and renewable.

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 non-renewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the wind blows throughout the year. The five types include solar energy from the Sun; geothermal energy from heat within the Earth; hydroelectric energy from moving water; biogas from dead plants and microorganisms and finally, energy from the wind.

Task 1. Reading the passage and decide whether the followings statements are true (T) or false (F)

Television is a product that was invented in 1926 and has been developed over many years and it still continues to be developed. The television was one of many great inventions in the 20th century.

The television is an extremely popular product. Over the years many people have bought the television. Now, there are over 15,000 T.V channels in the world. It is clear that the television is a popular product but it is also bad for your sight. People spend almost 4-8 hours in front of a screen (about a sixth to a third of a day). This results in less time to be physically active, spending time with family, doing homework to the best of their ability and reading. This is bad as reading has been proved to affect how smart you are. Also there are many inappropriate television shows that "hypnotize" children into thinking that something wrong is right or something bad is good. On the other hand, some may argue that television can be good for your education as some television programs are documentaries, contain historical facts and help children stay up to date with the world around them (the news). I think that the television can be good for you if you can control how long you are on it and you watch the right types of programs however, even if you do watch good programs, it will still have an effect on your health and sight.

Nam: Yes, I have. I've also stopped eating fast food and given up bad habits, such as staying up late.

Mark: I can't believe it! I thought you can't live without burgers and chips!

Nam: I know. I ate a lot of fast food, but now I prefer fresh fruits and vegetables.

Mark: So what happened?

Nam: Well, it was my grandfather. I visited him during my last summer holiday and have learnt a lot of important life lessons from him.

Mark: Really?

Nam: Yes. He's a wonderful person. He has just had his 90th birthday, but he's still full of energy!

Mark: Amazing! How does he stay so active?

Nam: Well, he does exercise every morning, goes to bed early, and eats a lot of vegetables. We spent a lot of time together cooking, working in his garden, and walking in the parks. I've learnt from him that taking regular exercise and eating a balanced diet are the key to a long and healthy life.
