ENGLISH · LESSON 02 OF 20
Choose tense and voice for your meaning
What this lesson helps you do
Distinguish a general process from completed work and choose active or passive voice deliberately.
Before this lesson
This lesson builds on:
The explanation
Tense locates a statement in time or presents it as generally true. “The system records the temperature every minute” describes a routine. “The system recorded the temperature yesterday” describes completed work. A report can correctly contain several tenses because its sentences have different purposes. Consistency means a clear time relationship, not putting every verb in one tense.
Active voice names the doer before the action: “The team checked the sensor.” Passive voice makes the affected item the subject: “The sensor was checked.” Passive voice is useful when the item or procedure matters more than the doer. Active voice can be more direct when responsibility matters. Neither voice automatically makes a sentence more accurate or more academic.
Build an ordinary passive with a form of be and a past participle. Preserve time: is checked for a routine, was checked for a completed event. Some verbs do not normally take a passive because they have no object to promote: “The temperature rose”, not “The temperature was risen”. Follow any specific reporting conventions required by the course.
Language pattern
- Pattern
- Routine: the team checks / the sensor is checked. Completed work: the team checked / the sensor was checked.
- What it does
- Time and focus are separate choices.
- Limits
- Changing voice should preserve the underlying event. It can change emphasis or remove information about who acted.
A first worked example
A general process
Situation. A short guide explains how an ordinary water-filter system operates.
Water enters the filter. The filter removes suspended particles. The filtered water is collected in a tank.
Why it works
- Present tense describes the general sequence.
- The second sentence uses active voice because the filter is a useful subject.
- The third uses passive voice to keep attention on the water.
What it shows: Mixed voice is appropriate when each sentence remains clear.
A second worked example
A completed investigation
Situation. A team describes what it actually did on Monday.
We checked the balance before the trial. Each sample was weighed twice, and both readings were recorded.
Why it works
- Checked, was weighed and were recorded all locate the actions in the completed investigation.
- We makes responsibility clear in the first sentence.
- Each sample is singular; both readings is plural.
What it shows: The passive does not require present tense. It follows the time of the event.
Common mistakes
Draft (not correct): The students was asked to submit the report.
Revision: The students were asked to submit the report.
The auxiliary agrees with the plural subject.
Draft (not correct): Passive voice is always more scientific.
Revision: Choose the voice that makes the action and responsibility clear.
Voice is a communication choice, not a quality score.
Keep in mind
- State a routine in present tense when appropriate.
- Use past tense for completed procedures when appropriate.
- Preserve meaning when changing voice.
Foundation lesson; not an official syllabus, accredited CEFR placement, or score prediction.
Next: Keep subjects, articles and references clear. Make it clear what a sentence refers to and which noun controls its verb.
