难道你不知道在图书馆内是禁止抽烟的吗

"Is there a smoking area in the library?"

In most libraries, smoking is not allowed inside the premises due to fire safety and health considerations. However, some libraries may have designated outdoor smoking areas. It is always best to check the library's specific rules and regulations regarding smoking before visiting. If there is no smoking area, it is important to respect the rules and find an appropriate place outside the library to smoke, if permitted by local laws. Remember that the library is a public space, and it is essential to consider the comfort and wellbeing of others.
