Why do big public projects so often cost more and take longer than planned?
[Bài tập luyện nói]
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.

- 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").

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

[Bài tập luyện nói]
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:
