—Terrible. I have lots of work to do and I lost my phone this morning.

Feet are an important part of you. Without them, you couldn't stand up, walk or run around. Your feet work so hard that sometimes they get sweaty (出汗).

Think of a hot summer day when you have been walking around all afternoon. Your feet have been in those trainers for a long time! The moment you take off your shoes, you feel good and relaxed, but your feet smell bad. You may think it is because of the sweat. But in fact, sweat itself has no smell. It's the bacteria (细菌) on your skin (皮肤) that mix with it and gives off a bad smell.

Bacteria love dark and wet places like the inside of sweaty shoes. The sweatier you get, the more bacteria there will be. When you wear your shoes, bacteria will have a good meal on your feet. They eat dead skin cells from your skin and then leave a kind of waste called organic acids (有机酸). These organic acids smell bad. Things will become better if you wear cotton socks.

—OK. I will make sure everyone here can hear me.

American people like to say "Thank you." when others help them or say something kind to them. People in many countries do so too. It's a very good habit (习惯). You should say "Thank you." when someone passes you salt on the table, or when someone says you do your work well, you buy a nice thing, or your city is very beautiful. "Thank you." is used not only between friends, but also between parents and children, brothers and sisters, husbands and wives.

    "Excuse me." is another short sentence they use. When you hear someone say so behind you, you know that somebody wants to walk past you and doesn't want to hit you.

    It's not polite to interrupt (打扰) others when they are talking. If you want to speak to one of them, say "Excuse me." first, and then begin to talk. You should also do so when you want to cough or make some noise before others. Let's learn to say "Thank you." and "Excuse me.".

—No, you. My dad is sleeping. (must (not)/ may(not) /can(not))
