Thanks for joining me in this week's The Natural World. I'm Rebecca. Tonight, I'll share some interesting facts about electricity with you. First of all, as you may already know, electricity was not invented. It was discovered. But do you know when it was first discovered? Many believe that electricity was first discovered by the Ancient Greeks more than 2,500 years ago. They produced electricity by rubbing fur against smooth stone! Next, do you know how fast electricity travels? The answer is: the speed of light! That is, about 300 million metres per second! Another interesting fact is about electric cars. They are very popular now, but the idea is not new. British inventor Rober Anderson invented the first electric car around 1832. However, this car was not very useful. It wasn't possible to drive electric cars until the second half of the 19th century. Finally, we are always trying our best to make good use of this energy, but according to a report, billions of pounds of electricity is wasted every single year in the UK. And another report shows that in the USA, about 30% of the electricity used in offices each year is wasted. This just shows how important it is to save electricity in our daily lives. That's all from me today. I hope you enjoyed learning a bit more about electricity. 听力材料 Activity 2 3 Listen again and complete the notes.
