My calculator works off solar - power which means I don’t have to buy batteries., It’s time to get these dirty clothes into the washing - machine before they smell., I’d love to travel to Mars. Maybe one day space - travel will be possible for all of us., Some people think it’s dangerous, but nuclear - power provides us with a lot of energy., Can you get the vacuum - cleaner out and clean the carpets?, Some people worry about genetic - engineering and how it’s used in farming., As the IT manager, I have to make sure the computer - networks are operating properly., We wouldn’t have mobile phones if communication - satellites didn’t exist.,
