 This is Mark. I'm doing great. Thanks for asking. I met Mary at the bus stop yesterday. He published his book only in Italy. They sat on the floor to watch TV. In this lesson we're going to look at prepositions of place. So stay tuned. Sometimes I've been thought about which preposition to use. Well, it's important that you learn the verb plus the preposition. For example, I went to Japan last year. I went to, so I go to. I stayed in Japan for a month. Stay in. So I learned the verb plus the preposition. If you wish to watch a lesson on prepositional verbs, you may click here. Now, let's concentrate on these prepositions, prepositions of place. At, in and on. I listed some rules to follow. The first one, at. At we use it for an exact point. My example was, I met Mary at the bus stop. So this is, let's imagine, the bus stop right here. And I'm standing there. I met her at the bus stop. So we also can say, I met her at the corner. Or at the door, at the door of a neighbor. At the end of the road, for example. Now, we also use at with public spaces or buildings. So I met her at university. I met her at the cinema. Or I met her at the library. We can say also without the article, the, at hospital. We also use at for events. So we can also say with, I met Mary, I met Mary at the party. Or I met Mary at the concert. Or at the wedding, I met her at the wedding. There are some expressions that use at. These are, not all of them, but some are. At home, we don't use the article of love. So at home, we say. Or at the top, or at the bottom. Or at the table, I sat at the table in front of you. At the sign, etc., etc. Let's look at in. In is used for enclosed space, so inside. Including countries. Like my example. He published his book only in Italy. In Italy, in France, in Russia, in Canada, in the US. In a box. In a building, so enclosed space. Some means of transport with some. In a car. A car is usually small, right? So in a car. In a helicopter. In a ship. In the lift. Or if you want to be American, in the elevator. Elevator. It's the same as lift. With expressions. In the sky. In the sky, there are many birds. In Main Street. Pay attention, because if you had a number. In 58 Main Street. It wouldn't be in 58 Main Street, but on 58 Main Street. So in takes only the name of the street. In Main Street. On 58 Main Street. In the newspaper. In the mirror. I looked in the mirror. In the picture. In the world. In their world, there are many people who speak English. Let's take a look at on. On for surface. It could be horizontally or vertically. They sat on the floor. They sat on the floor. Or there is a sign on the door. Or on the ceiling. There is a fan on the ceiling. On the table. On the table there are many glasses. So with means of transport. On the bus we say. On the train. On the plane. On a horse. On a horse. And on a bike. Expressions. Suspressions that take on. On the radio. I heard it on the radio. On TV. I watched it on TV. On the way. On the way to work. I met Mary. On the rides. On the left. On the river. On the sea. Etc. Now let's recap. In this lesson we looked at prepositions of place. At. In and on. Use at for an exact point. Body spaces or buildings. And events. Use in instead for an enclosed space. And some means of transport. Use on for a surface. And for some means of transport too. Remember the fixed expressions. At home. At hospital. In the mirror. In the picture. On the radio. On TV. So that's it for today. Thank you very much for watching.
