Do you like to go to the library? We usually go to the library at weekends. There are many books and computers in it. We can read books or study on the computers. In the library, we can see some signs on the walls. We should stand in line when we go into the library. We can't eat or drink there. We can't talk loudly. We can't spit. We can't smoke. We can borrow books. But we must return books on time.
