How are you? Today let's look at some international standards for electrical plugs and sockets.
Look at the picture above. It's an illustration of a electrical plug and socket set from the U.S. from the early 20th century. It's very different from what we have today, isn't it?
Activity
Look at the pictures below. They show different configurations of plugs and sockets from different countries (and areas). Can you guess, and match, the correct configurations with the correct countries and areas?
When you match, describe shapes and configurations as ways to help you guess, and try to remember, where the plugs and sockets might be used.
例えば：A: This socket has two round holes, plus a third one that's semi-circular. The bottom one is the earth, and it's set in a little from the surface for the plug to go in. I'm guessing that it comes from Europe - maybe Northern Europe. I'm not sure, but that's my guess. What do you think?
B: You might be right. We can look this up on the internet. So how about this one? It has three pins on the plug, and the earth is set in a different direction. Where do you think you'd find this? I think maybe in...

U.S./Canada (North America) & Japan Italy (southern Europe)
the U.K & Ireland Russia (parts of eastern Europe)
Denmark (northern Europe) Germany (most of the EU)

Homework
When you are finished, do a little research and find out where these plugs and sockets are used.
Take care! See you next class!
