IELTS speaking examples
These original practice prompts are not official test questions or scored answers. Adapt the language to your own experience. The Part 2 extract is an opening to expand into a longer response.
Part 1
What do you do to reduce waste?
I reuse bags and try to plan meals before shopping. That helps reduce food waste. I also recycle the materials accepted by our local collection service.
Practise: Give specific actions rather than claiming every item is recyclable.
Part 2 — sample opening
Describe a natural place you would like to protect.
I would like to protect a wetland near my town. It provides a habitat for birds and gives people a quiet place to walk. Recently, volunteers removed litter and began a conservation project with local schools.
Practise: Continue with where it is, what threatens it and how people could help.
Part 3
Who should be responsible for protecting the environment?
Individuals can reduce waste, but businesses and governments influence larger systems. For example, transport planning can affect emissions across a city. I think responsibilities should be shared, with clear goals and practical ways to measure progress.
Practise: Connect vocabulary to a reasoned distinction between individual and wider action.
