1. There is a girl standing ON the bridge. Why is she crying? - She has dropped her doll INTO the water. There is no tea IN my cup. Pour some tea INTO my cup. Put these flowers ON the window-sill. I saw many people ON the platform waiting for the train. We went TO the garden and sat down ON a bench.
2. In winter I usually go to bed AT ten o'clock because I learn IN school and have to get up early. But IN summer, when I don't go to school and live IN the country, I like to go TO bed late. Do you like to read IN bed? We did not want to stay IN town on such a hot day, so we went TO the country.
