Answer:
1. New dentures are wanted by the man with no teeth.
2. Storms are forecast for tomorrow by the weatherman.
3. The chest of drawers was made by my grandfather for my wedding present.
4. Lives are saved everyday by the talented cardiac surgeon.
Explanation:
When we change the active voice structures to passive voice structures, the subject of the active sentence becomes the object in the passive sentence. For instance, "talented cardiac surgeon" was the subject of the active sentence, while in the passive sentence, this noun phrase is the object. Passive forms consist of verb to be and past participle of the main verb - are + saved.
