Passive Form
In passive sentences, the thing receiving the action is the subject of the sentence and the thing doing the action is optionally included near the end of the sentence. You can use the passive form if you think that the thing receiving the action is more important or should be emphasized. You can also use the passive form if you do not know who is doing the action or if you do not want to mention who is doing the action.
[Thing receiving action] + [be] + [past participle of verb] + [by] + [thing doing action].

Example Article Passive Sentences
For most modern airports, the major design problem is scale how to allow adequate space on the ground for maneuvering wide body jets while permitting convenient and apid movement of passengers departing, arriving, or transferring from one flight to another.
Most designs for airport terminals take one of four approaches. In the linear plan, the building may be straight o curved. The passengers board aircraft parked next to the terminal. This plan works well for small airports that need to provide boarding areas for only a few aircraft at a time.
In the pier plan, narrow corridors or piers extend from a central building. This plan allows many aircraft o park next to the building. However, it creates long walking distance for passengers.
In the satellite plan, passengers board aircraft small terminals that are separated from the main terminals. Passengers reach the satellite by way of shuttle trains or underground passengers ways that have shuttle trains or moving sidewalks.
The transporter plan employs some system of transport to move passengers from the terminal building to the aircraft. If buses are used, the passengers must climb a flight of stairs to board the aircraft. If mobile lounges are used, they can link up directly with the aircraft and protect passengers from the weather.
