Language Goal
Ask for permission politely
Request politely
Ask for permission
Do the dishes. Take out the trash. Do your parents say these things to you? Of course they do. Why? Well, someone has to do it. They're chores - small everyday duties. You may get money for doing a chore, you may not. Your parents may tell you to do it, or they may not. Parents and other people don't always give commands. Sometimes they ask. How do you ask politely? In English, the word could is often used for requests. Remember when your friend invited you to her party? or the time you asked your parents if you might stay up late? If you use could, it's a nice way of asking permission. And when your mom yells "Could you make your bed?" she's asking you "politely" to do a chore. So what are chores?
