Answer:
Since all the sentences are in the active voice, let's change them into the passive voice:
1. A sweet song is sung by her.
2. Is hockey not played by you?
3. Are lottery tickets sold by him?
4. Branches are being bent by me.
5. Are potatoes being boiled by her?
6. Is tea being brought by the servants?
Explanation:
When changing a sentence from the active voice to the passive voice, we must follow a few steps:
1. Find the object of the verb. It will become the subject of the sentence in the passive voice.
2. Identify the verb and its tense. The tense must be kept, but we must add the auxiliary verb "be".
3. Transform the subject of the active voice into the agent of the passive voice. It comes preceded by the preposition "by".
Take a look at the example below for illustration:
- My mother has baked a cake.
→ my mother: subject
→ has baked: verb, present perfect
→ a cake: object
Following the instructions above:
→ a cake: subject
→ has been baked: verb, present perfect + "be"
→ by my mother: agent
- A cake has been baked by my mother.
