The passive voice focuses attention on the action, result, process, or receiver of an action, rather than on the person performing it.
The object of the active sentence becomes the subject of the passive sentence.
Several changes are being introduced to the city's public transportation system. Currently, older buses are being replaced with more energy-efficient vehicles, and several new routes are being developed for growing neighbourhoods. Public feedback is collected through online surveys and community meetings, and the results are carefully reviewed before final decisions are made. Although some residents have concerns about the changes, the new system is expected to improve transportation throughout the city.
CLB 9+ Tip: The passive voice is not simply another grammatical form. It allows you to control what information receives the most attention.
Use the present simple passive for actions, processes, rules, procedures, and situations that happen regularly or generally.
Use by + agent when the person or organization performing the action is important.
However, the agent is often omitted when it is:
Remember: In many passive sentences, the important information is what happens, not who performs the action.
Use the present continuous passive for an action or process that is happening now, around now, or during a temporary period.
CLB 9+ Tip: The present continuous passive is especially useful for describing current developments, workplace changes, construction, investigations, and ongoing problems.
At CLB 9+, passive structures can make speaking more precise, flexible, and appropriately formal.
Use the passive when the action, situation, or thing being described is more important than the person performing the action.
This can be especially useful when describing scenes, places, and arrangements.
This allows you to describe what is happening without repeatedly using expressions such as “someone is...” or “they are...”.
The passive focuses attention on the change or development.
The passive version focuses attention on the problem rather than directly blaming a person. This can be useful when discussing workplace problems, complaints, disagreements, or sensitive situations.
Some passive structures are particularly useful at higher levels because they allow us to report an expectation, opinion, or general belief without identifying one specific person as the source.
Speaking Tip: Use the passive when you want your listener to focus on what is happening rather than repeatedly identifying who is performing each action.
The passive voice is especially common in formal and professional writing because it can create a more objective and impersonal tone.
The passive is useful when the process itself matters more than the people performing each step.
The passive can make a complaint sound more professional and less directly accusatory.
These structures focus attention on facts, procedures, and developments rather than on individuals.
Writing Tip: At CLB 9+, choosing between active and passive voice is often a question of focus and tone, not simply grammar.
The passive voice allows you to control which part of the message receives the most attention.
| Form | Structure | Main Use |
| Present Simple Passive | is / are + past participle | regular actions, procedures, facts |
| Present Continuous Passive | is / are + being + past participle | actions currently in progress |
| Negative Simple | is / are not + past participle | actions that do not occur |
| Negative Continuous | is / are not being + past participle | actions not happening now |
| Agent | by + person / organization | identifies who performs the action |
Final CLB 9+ Tip: Advanced writing does not mean making every sentence passive. Strong speakers and writers choose between active and passive voice strategically. The goal is to control the focus, tone, and emphasis of the message.
