1. The student tried to make the teacher think that his report was original, but the teacher knew it wasn’t, and called him on the carpet.
2. I got called on the carpet for being late again.

Synonyms: rake (someone) over the coals; chew (someone) out; read (someone) the riot act. This phrase originates from the military, where it used to be that only senior officers had carpet in their offices. To be called on the carpet meant that a lower-ranking soldier was brought into the senior’s office to be formally reprimanded for an offense.
