Question

Answer 1

my project will be completed by me the next comming week

Answer 2

In a sentence with an active voice,  the action is performed by the subject which is denoted by the verb. In other words, the subject is the doer of the  action. Whereas in a passive voice,the verb acts upon the subject.

Passive voice is the voice used to show an interest in the object or person who experienced the action rather upon the action performer. In passive voice, a subject is an important thing.

Therefore, the above sentence in passive voice would be written as:

In the coming week, my project will be completed by me.
