Imagine that you are preparing a project with your friend. You have found some interesting material for the presentation and you want to read this text to your friend. You have 1.5 minutes to read the text silently, then be ready to read it out aloud. You will not have more than 1.5 minutes to read it.

Electricity has changed our life in many ways. We can now stay up longer and devote more time to work, studies or entertainment because we don’t depend on the daylight anymore. Still, lighting your home needs energy, and you should never forget about energy-⁠saving measures in your household. If you want to run an eco-⁠friendly household, an important thing is to invest in the right light bulbs. Energy-⁠saving light bulbs are more efficient than the old ones. They have actually been in our shops for a long time, but it has taken people much time to come round to the idea. Energy-⁠saving light bulbs are slightly more expensive than ordinary ones but they are certainly not a waste of money. Such light bulbs use much less electricity thus cutting your electricity bill down. They also last longer, which means you don’t have to spend money replacing them. One energy-⁠saving light bulb can substitute six ordinary ones.
