Introduction
IELTS Speaking Part 3 and many Writing Task 2 essays require you to compare topics, evaluate viewpoints, and hypothesise about possible situations. Examiners expect you to move beyond simple opinions by discussing advantages, disadvantages, making contrasts, and imagining consequences. These advanced functions show your ability to think logically and use English flexibly.
Key Term: Compare
To explain similarities and/or differences between two or more topics, arguments, or examples using appropriate structures and vocabulary.Key Term: Evaluate
To judge the strengths, weaknesses, or overall value of an idea, argument, or option by analysing its advantages and disadvantages.Key Term: Hypothesise
To discuss situations that are imaginary, possible, or not yet real, using suitable language to show you are speculating or making predictions.
Approaching Part 3 Discussion: Understanding the Functions
IELTS Part 3 questions require deeper thought than simple personal opinions. The most common functions you must address are:
- Comparing: How are two things similar or different?
- Evaluating: What are the benefits and drawbacks? Which idea is stronger?
- Hypothesising: What might happen if circumstances change? What could result from a possible action?
These skills are fundamental for higher IELTS band levels.
Comparing: Presenting Similarities and Differences
When comparing, you must clearly state what is the same and what differs.
Key Term: Linking Phrase
A word or group of words used to connect and relate ideas, such as 'however', 'in contrast', 'both', or 'whereas'.
Useful Structures and Phrases
To show similarity:
- Both (topics)...
- Similarly, ...
- In the same way, ...
To show difference:
- However, ...
- In contrast, ...
- While (A), (B) ...
- Unlike (A), (B) ...
Model Speaking Turn
"Both traditional books and e-books provide information, but unlike printed books, e-books are portable and convenient to carry."
Evaluating: Judging Arguments or Opinions
Evaluation means giving reasons or evidence to support which idea is stronger, more useful, or more important.
- What are the advantages and disadvantages?
- Which is better or more effective? Why?
Useful Language
Introducing strengths:
- One major advantage is...
- A key benefit is...
Introducing weaknesses:
- On the other hand, ...
- A potential drawback is...
- However, there are some disadvantages...
Weighing up:
- Overall, I believe... because...
- Although (A) has clear benefits, (B) may be preferable due to...
Linking Words for Balanced Discussion
- Furthermore, ...
- Nevertheless, ...
- Consequently, ...
- For example, ...
- As a result, ...
Hypothesising: Talking About Imagined or Future Possibilities
Hypothesising involves speculating about situations that are not real, not certain, or are predictions.
Useful Structures
- If + past tense, would + base verb (imaginary present/future)
- If + past perfect, would have + past participle (imaginary past)
- Provided (that) ..., Unless ..., Assuming ...
Examples
"If everyone switched to electric cars, air pollution in cities would probably decrease."
"Suppose the government raised taxes on fast food; people might choose healthier options."
Worked Example 1.1
The number of people living in large cities is increasing each year. Some believe this trend brings prosperity, while others are concerned about stress and overcrowding.
Question: Compare the potential benefits and drawbacks of more people moving to cities. Which argument do you find stronger? Why?
Answer:
One benefit of urban growth is the availability of better jobs and improved services, such as hospitals and schools. However, a drawback is increased congestion and rising living costs. For instance, city dwellers may struggle to find affordable housing. Overall, while the economic advantages are significant, I think the disadvantages, especially regarding quality of life, are more serious.
Worked Example 1.2
Examiner: How would life change if public transport was completely free?
Answer:
If public transport were free, more people might leave their cars at home, resulting in less traffic and pollution. However, free transport could be overcrowded if the system cannot handle the extra demand. Overall, it could make cities cleaner and less congested, provided the government invested in expanding services.
Worked Example 1.3
Some schools now use only online classes. Others believe face-to-face learning is more effective.
Question: Evaluate both approaches and hypothesise what might happen if all classes moved online.
Answer:
Online classes offer flexibility and convenience. On the other hand, they may reduce student motivation and limit social interaction. If all classes switched to online-only, some students could succeed, especially self-motivators, but others might struggle without face-to-face support from teachers. Therefore, a mix could be more effective than relying solely on digital learning.
Exam Warning
Answering only one side (e.g., listing advantages without any disadvantages) may lower your band score. Discuss both positive and negative points for balanced evaluation, even if a question asks for your opinion.
Revision Tip
Practise starting hypothetical statements with 'If...' or 'Suppose...', and using modal verbs like 'might', 'could', or 'would'. This shows flexible English.
Summary
When answering IELTS Part 3 discussion questions, focus on comparing, evaluating, or hypothesising as required. Use linking words and balanced arguments. Give clear examples and support conclusions with reasons. Show you can speculate about future or unreal situations using correct grammar.
