“Could have been” is a powerful grammatical structure that allows you to speculate about past possibilities. In IELTS, mastering this construction can significantly enhance your ability to express complex ideas and hypothetical scenarios, particularly in the Speaking and Writing sections. Let’s explore how to effectively use “could have been” for past speculation and how it can boost your IELTS score.
Understanding “Could Have Been” in Context
The structure “could have been” is used to talk about possibilities in the past that didn’t happen. It’s a combination of the modal verb “could” (expressing possibility), “have” (auxiliary verb), and “been” (past participle of “be”). This structure is particularly useful in IELTS when you need to discuss hypothetical situations or express regret about past events.
Here are some examples to illustrate its use:
- “The concert could have been amazing if the singer hadn’t lost her voice.”
- “I could have been a doctor if I had studied harder in school.”
- “The project could have been completed on time if we had more resources.”
- “She could have been happier in her job if she had chosen a different career path.”
- “The accident could have been avoided if the driver had been more careful.”
In each of these sentences, we’re speculating about a past possibility that didn’t occur. This structure allows us to explore alternative outcomes and discuss “what if” scenarios.
Grammar Formula and Usage in IELTS
The basic formula for using “could have been” is:
Subject + could have been + past participle/adjective/noun
It’s crucial to remember that this structure is used for past possibilities, not present or future ones. In IELTS, you can use this structure in various ways:

IELTS Writing

Sample Passages Using “Could Have Been”
Let’s look at how “could have been” can be incorporated into longer passages for IELTS Writing Task 2:
Topic: The Impact of Technology on Education
“While technology has undoubtedly revolutionized education, its implementation could have been more effective if educators had received proper training. Many schools rushed to adopt new technologies without considering how they could have been integrated seamlessly into existing curricula. As a result, the potential benefits of these tools could have been fully realized if a more strategic approach had been taken. For instance, interactive whiteboards could have been used more effectively to engage students if teachers had been taught innovative teaching methods. Similarly, online learning platforms could have been more successful in promoting self-directed learning if students had been given better guidance on how to use them effectively.”
In this passage, “could have been” is used multiple times to speculate about alternative outcomes and missed opportunities in the implementation of technology in education.
