To convert the given sentences into the passive voice, we need to rearrange the structure of the sentences to focus on the receiver of the action rather than the doer of the action. Here are the sentences in the passive voice:
- Many students in Porto are taught by Neil.
- Cakes are baked by Joana every day.
- My car was repaired by my friend.
- English is spoken by many students in my class.
- My best friend was arrested by the police.
- Her homework was finished by eight o'clock.
- This broken table was not repaired by anybody.
- Are the letters being typed by them?
- All the questions were answered by him.
- The truth wasn't told to me by them.
- The girl is smiled at by them as she walks by.
- The bicycle is not kept in the garage by them.
- Your friend is spoken well of by people.
- Money is thought to be the most important thing in life by teens.
- Robots are made from strong metal.

- The problem is being solved by them now.
- The students were allowed to leave earlier on Thursday.

By transforming the active voice sentences into the passive voice, the focus shifts from the doer of the action to the receiver of the action, resulting in sentences that emphasize what is being done rather than who is doing it.
