To complete the sentences with "at" or "on," we need to consider the appropriate use of prepositions in English language.
- at the airport
- on the motorway
- on the toll bridge
- in the garage
- at the bus stop
- on the road
- in the harbour
- on the platform
- at the station
Now, let's form sentences using reported speech based on the given example:
Original sentence: They told us that they had met John at the airport while they were waiting for their flight to be announced.
Reported speech sentence: They said that they had encountered John at the airport when they were waiting for their flight to be announced.
Feel free to create more sentences using the prepositions "at" and "on" and incorporating reported speech for practice and deeper understanding.
