Door
From Simple English Wikipedia, the free encyclopedia
A door is a hard, flat thing you can open and close so you can go into a room or other place. It is found in houses and other buildings. Doors are also found in cars and cages.
The reasons for a door are:
- for people, animals, and objects to go through; some doors are for emergencies only (emergency exit)
- to keep cold or hot air outside (or inside, such as the door on a refrigerator)
- so that people cannot see or hear what happens on the other side (privacy and stopping noise)
- so that people do not fall out of the car or other vehicle
- so you can decide who to let in--many doors have a lock
[edit] Types of doors
A revolving door is a group of doors that turn in a circle as you push one. You can go through, but wind and rain cannot get in.
A blind door is a fake door that is really part of the wall. People use them to make a room look nice.
An up-and-over door is often used in garages. Instead of hinges, it rolls up on rails so that it stays above the opening.
A fire door is a door that does not let fire go through. They are usually made of heavy steel.
