Understanding the Simple Past Passive Tense
Definition and Purpose
The simple past passive tense is a grammatical construction used to express actions completed in the past where the subject receives the action. Unlike the active voice, which emphasizes the doer of the action, the passive voice shifts focus to the recipient. For example:
- Active voice: "The chef cooked the meal."
- Passive voice: "The meal was cooked by the chef."
In the passive version, the emphasis is on "the meal," the recipient of the action, rather than "the chef," the doer.
When to Use the Simple Past Passive Tense
The simple past passive tense is appropriate in various contexts:
- When the agent (the doer) is unknown: "The window was broken."
- When the agent is unimportant or obvious: "The documents were signed yesterday."
- When the focus is on the action or the object receiving the action: "The new policies were implemented last year."
- In formal writing, reports, or scientific descriptions: "The experiment was conducted by the researchers."

Forming the Simple Past Passive Tense
Structure
The structure of the simple past passive tense is straightforward:
- Subject + was/were + past participle (+ by + agent [optional])
The choice of "was" or "were" depends on the number of the subject:
- Singular subjects: "was"
- Plural subjects: "were"
The main verb is always in the past participle form.
Examples of Formation
1. Active: They built the bridge.
Passive: The bridge was built by them.
2. Active: The students completed the project.
Passive: The project was completed by the students.
3. Active: The company launched a new product.
Passive: A new product was launched by the company.
4. Active: Someone stole my bicycle.
Passive: My bicycle was stolen.
Note: The agent (introduced by "by") is optional; sometimes, it can be omitted if irrelevant or unknown.

How to Convert Active Sentences to Passive in the Past Tense
Converting sentences from active to passive in the simple past tense involves a few steps:
1. Identify the object of the active sentence.
2. Make that object the subject of the passive sentence.
3. Use the correct form of "was" or "were" depending on the new subject.
4. Use the past participle of the main verb.
5. (Optional) Include the original subject preceded by "by".
Conversion Steps:
| Step | Active Sentence | Passive Sentence |
|--------|------------------|------------------|
| 1 | Subject + verb + object | Object + was/were + past participle + (by + subject) |
| 2 | "The mechanic fixed the car." | "The car was fixed by the mechanic." |
Example:
- Active: The teacher graded the exams.
- Passive: The exams were graded by the teacher.
