IELTS Speaking Part 3 Practice

Record your answer for each question and compare it with the model response.

Question 1

Should a public inquiry be led by a judge, or by experts from the field in which the accident happened?

Record Your Spoken Answer (AI Graded):

[Bài tập luyện nói]

💡 Show C1 Model Answer & Key Phrases ▼

"Well, honestly, it's hard to say. I'd lean towards having a judge in charge, but, um, with technical experts right beside them. You see, a judge brings unbiased oversight and knows how to weigh evidence without taking sides. On the other hand, if an inquiry looks into a plane crash, you definitely need specialists who get to the bottom of complex engineering faults. I remember when my uncle's factory had a minor safety review - the legal team kept things fair, but the engineers knew what actually broke. So, having a judge lead while relying on expert testimony really strikes the right balance."

Key Spoken Phrases & Notes:

• unbiased oversight: neutral, independent supervision without conflict of interest
• get to the bottom of: discover the underlying truth or cause of a problem
• strikes the right balance: achieves a good, fair compromise between two contrasting sides

Question 2

Is it fair to blame one person for an accident that many people could have prevented?

Record Your Spoken Answer (AI Graded):

"Personally, I don't think it's fair at all. When something goes wrong, it's rarely just one person's fault; usually, there's a whole chain of systemic failures behind it. If supervisors and coworkers noticed a hazard earlier and said nothing, they share the responsibility too. Scapegoating one worker just lets the organization off the hook. Um, I once saw a colleague get blamed for a missed deadline at work, even though three separate departments failed to send him the data. So, pinning everything on a single operator usually obscures the bigger picture and stops real safety improvements from happening."

Key Spoken Phrases & Notes:

• systemic failures: fundamental flaws rooted across an entire organization or procedure
• off the hook: freed from blame, responsibility, or obligation
• obscures the bigger picture: hides the broader context or root causes of an event

Question 3

Should the families of victims be allowed to take part in an inquiry?

Record Your Spoken Answer (AI Graded):

[Bài tập luyện nói]

💡 Show C1 Model Answer & Key Phrases ▼

"Yes, absolutely, though with some boundaries. Families deserve complete transparency about what happened to their loved ones, so they should be allowed to attend hearings and ask questions through legal reps. It gives them a sense of closure after a traumatic event. However, um, they probably shouldn't direct the technical investigation itself, because emotions can run high and might accidentally derail the process. I remember watching my friend's family go through a formal workplace hearing; just being heard made a huge difference to them. So, including victims' families is vital for accountability, provided the panel stays objective."

Key Spoken Phrases & Notes:

• complete transparency: total openness without concealing any information
• a sense of closure: a feeling of resolution that helps someone overcome grief
• derail the process: disrupt or divert an ongoing procedure from its course

Question 4

Do you think companies are honest enough when they report their own mistakes?

Record Your Spoken Answer (AI Graded):

[Bài tập luyện nói]

💡 Show C1 Model Answer & Key Phrases ▼

"To be blunt, not usually. Most corporations are terrified of financial losses or reputational damage, so their natural reaction is to downplay the severity of their errors. They might admit to a minor hiccup while glossing over major safety lapses. Well, um, it usually takes pressure from independent investigators or journalists to bring the truth to light. I once bought an appliance brand product that was recalled quietly without explaining the fire risk. So, unless there are strict legal penalties for hiding mistakes, companies will almost always try to sweep things under the carpet to protect their profits."

Key Spoken Phrases & Notes:

• downplay the severity: make a serious problem appear less important or harmful
• bring the truth to light: uncover and reveal facts that were previously hidden
• sweep things under the carpet: hide an embarrassing problem or mistake to avoid trouble

Question 5

Why do the same kinds of accidents seem to happen again after an inquiry has made its recommendations?

Record Your Spoken Answer (AI Graded):

[Bài tập luyện nói]

💡 Show C1 Model Answer & Key Phrases ▼

"I think it mostly comes down to cutting corners and a lack of enforcement. Inquiries often produce brilliant recommendations, but implementing them costs money and takes time. Over time, management gets complacent, and old habits creep back in. Um, it's like when people fix a leaky roof at home - they patch it up quickly, but forget to replace the old pipes, so it leaks again next winter. Unless regulatory bodies tighten the screws with regular inspections, companies treat safety guidelines as optional paperwork. That's why systemic flaws repeat themselves despite all the costly official reports."

Key Spoken Phrases & Notes:

• cutting corners: doing something quickly, cheaply, or carelessly to save money or effort
• complacent: overly satisfied with current conditions while unaware of hidden dangers
• tighten the screws: increase pressure, control, or strictness on an operation

Question 6

Should the results of an accident investigation always be made public, even if they embarrass the people involved?

Record Your Spoken Answer (AI Graded):

[Bài tập luyện nói]

💡 Show C1 Model Answer & Key Phrases ▼

"Without a doubt, yes. Public safety must always take precedence over anyone's personal or corporate reputation. If an investigation reveals embarrassing negligence or incompetence, publishing the full findings is the only way to hold people accountable and prevent similar disasters. Well, um, if officials cover up mistakes to save face, the public loses trust in the entire system. It's like when a local school publishes an audit report; it might be embarrassing for the board, but parents need to know the truth. Transparency is essential so everyone can learn from failures and implement watertight safety standards."

Key Spoken Phrases & Notes:

• take precedence over: be considered more important than something else
• hold people accountable: force individuals to accept responsibility for their actions
• watertight safety standards: extremely rigorous and reliable safety rules with no flaws
