Question

active or passive voice
active voice

• the subject is the doer of the action

passive voice

• the action is being done to the subject

ask yourself:

• who is the sentence about?
• where is the verb in the sentence?
• did the subject do or receive the action?

which of the following is written in passive voice?
the sweets were purchased by us.
she has a sweet tooth.
we bought chocolate for my mom.

Explanation:

To determine passive voice, we check if the subject receives the action. For "The sweets were purchased by us", the subject is "the sweets", and the action (purchased) is done to them (by "us"). In "She has a sweet tooth" and "We bought chocolate for my mom", the subjects ("she", "we") perform the actions, so they are active.

Answer:

The sweets were purchased by us.
