01
IELTS Speaking Part 3 • Question 1

Why do big public projects so often cost more and take longer than planned?

[Bài tập luyện nói]

💬 View Model Answer & Key Natural Phrases Click to expand
"Well, honestly, it's pretty common for megaprojects to run over budget and face severe delays. At the outset, planners are often way too optimistic about costs and timelines just to get approval. Then, once digging actually begins, unexpected technical issues popping up can create a major bottleneck in construction. For example, when my city tried fixing a central bridge, workers unexpectedly hit underground utility pipes, which delayed everything by months. Plus, prices for raw materials tend to shoot up over time. So, in the long run, initial estimates usually end up being far too low."

Key Spoken Expressions:

  • run over budget — exceed initial cost estimates
  • At the outset — in the very beginning
  • bottleneck — a point where progress is severely blocked
  • in the long run — over an extended period of time

Why this works:

Uses natural spoken fillers ("Well, honestly") and links an initial reason directly to an everyday personal example about bridge repair.

02
IELTS Speaking Part 3 • Question 2

Should a government spend money on a huge project when many people need smaller local services?

[Bài tập luyện nói]

💬 View Model Answer & Key Natural Phrases Click to expand
"Well, I'd lean towards balancing both, but, um, local needs ought to come first. For the time being, if public transport in the suburbs is falling apart, spending billions on a grand new stadium feels completely unfair. I remember when my local bus route was cut while the city council funded a flashy glass tower downtown, and everyone was furious. That said, huge infrastructure schemes can lay the groundwork for economic growth, which benefits everyone in the long run. So, leaders shouldn't totally shelve big plans, but basic services definitely must be kept up to scratch first."

Key Spoken Expressions:

  • For the time being — for now / in the short term
  • lay the groundwork — prepare the necessary foundation
  • in the long run — over an extended time frame
  • shelve — put plans on hold
  • up to scratch — reaching an acceptable standard

Why this works:

Balances both sides smoothly using natural contrast markers ("That said") and everyday vocabulary ("flashy", "furious").

03
IELTS Speaking Part 3 • Question 3

How much should local people be asked before a new railway or road is built near their homes?

[Bài tập luyện nói]

💬 View Model Answer & Key Natural Phrases Click to expand
"Honestly, I think local residents should be consulted extensively right at the outset. Building a major highway right next to residential neighborhoods causes serious noise pollution and traffic disruption. If officials ignore the public, local groups will inevitably try to obstruct construction through protests or legal appeals, which just causes massive delays. I live near a main road, and when workers planned a new bypass, they held town hall meetings to adjust the route slightly. That kept everyone happy. So, involving residents early helps smooth out problems before heavy machinery even arrives on site."

Key Spoken Expressions:

  • at the outset — from the very beginning
  • obstruct — block or hinder progress
  • town hall meetings — public community consultation sessions
  • smooth out — resolve or eliminate difficulties

Why this works:

Demonstrates cause-and-effect reasoning with natural spoken phrasing and a concrete personal reference to community meetings.

04
IELTS Speaking Part 3 • Question 4

Is it better to finish a project quickly or to take longer and get it right?

[Bài tập luyện nói]

💬 View Model Answer & Key Natural Phrases Click to expand
"Well, in my view, it's definitely better to take extra time and focus on quality. Rushing a project to meet tight deadlines usually leads to poor workmanship, which means repairs will be needed almost immediately. I remember when a nearby bike lane was built by cutting corners near my apartment; within months, deep cracks appeared everywhere, forcing the council to postpone other jobs and rebuild it entirely. That ended up wasting way more money than doing it properly from day one. So, while speed is nice, ensuring safety and durability is what really matters in the long run."

Key Spoken Expressions:

  • poor workmanship — low quality construction work
  • cutting corners — doing a job too quickly or too cheaply, with less care
  • postpone — delay or defer until a later time
  • in the long run — over an extended future period

Why this works:

Gives a direct opinion, then a short everyday example ("deep cracks") to support it.

05
IELTS Speaking Part 3 • Question 5

Do famous buildings and bridges help a city more than ordinary improvements such as better buses?

[Bài tập luyện nói]

💬 View Model Answer & Key Natural Phrases Click to expand
"Well, honestly, it depends on what a city needs most. Landmark architecture can certainly put a city on the map, attracting tourists and investment. But, um, for everyday residents, reliable public transport makes a far bigger difference to their daily lives. In my town, for instance, adding electric buses cut my commute time in half, whereas a decorative monument nearby is just something nice to look at. For the time being, basic infrastructure should take priority over iconic structures. A city needs working public transport first, before spending big on status symbols."

Key Spoken Expressions:

  • put a city on the map — make a place famous or notable
  • makes a far bigger difference — has a much stronger effect
  • For the time being — for the present period
  • status symbols — things that show how rich or important a place is

Why this works:

Uses an idiom ("put on the map") naturally without sounding forced, and contrasts landmark tourism with personal bus commute routines.

06
IELTS Speaking Part 3 • Question 6

Who should pay when a big project fails: the builders, the officials or the taxpayers?

[Bài tập luyện nói]

💬 View Model Answer & Key Natural Phrases Click to expand
"Well, I'd say the financial burden ought to be shared based on who caused the error. If contractors deliver sub-standard work, they should definitely take responsibility and pay for the repairs. However, if city officials approved an unrealistic design at the outset or mismanaged funds, leadership needs to be held accountable too. Unfortunately, in reality, taxpayers often end up having to bear the brunt of massive cost overruns. I think strict legal contracts must be signed before construction begins so private firms and government departments can't just shift the blame onto ordinary citizens."

Key Spoken Expressions:

  • at the outset — at the start
  • bear the brunt — endure the main force or worst part of a problem
  • cost overruns — extra expenses exceeding the budget
  • shift the blame — transfer responsibility for a fault to others

Why this works:

Addresses a complex question by breaking down responsibility between contractors and officials with strong C1 spoken collocations.
