Omskriv verballed fra datid til nutid

Hej.

Jeg håber der er nogen der kan hjælpe med denne opgave, har prøvet at løse den men synes den er svær. 

Omskriv verballeddene (udsagnsleddene) i følgende tekst, sådan at præteritum (datid) ændres til præsens (nutid) og pluskvamperfektum (før datid) ændres til perfektum (før nutid). Streg ud i teksten og skriv det ændrede verballed ovenover.

Downstairs lamps had (have) been switched on against the gathering evening. The glare of parquet was (were) everywhere- a spotlighted alcove sheltered a pre-Columbian figure carved from stone. For a split second tom saw (sees) the miniature double of the squat brown man who had (has) let him into his house.
Paintings filled (fill) the walls. But Tom would (will) not allow himself to Linger before Posner’s trophies. Nevertheless, as he came (comes) to the open door of the room where the woman had (has) been vacuuming, he halted. Gleaming wood and muted jewel tones repeated (repeats) the message of wealth tempered by taste that the house had (has) been designed to communicate.

På forhånd tak.
