I went to the classroom early this morning.When I went into my seat,I found my chair broken.There was nobody else in the room then,and I changed chairs with Wang Ying,because her seat was just before mine.After awhile,Wang Ying arrived.When she saw the broken chair in her seat,she quickly went out and fetched some tools,then she began to repair it.When I saw this,my face went red and then I went to help her repair the chair.
