“Some people believe that governments should invest more money in public transport rather than in building new roads. To what extent do you agree or disagree?”🔊🎤🌐

✍️ Sample band 8.0 (296 từ)

Few debates in urban policy have proved as enduring — or as
consequential — as the question of whether public funds should be
channelled towards mass transit systems or towards the continuous
expansion of roadways. Having weighed both arguments, I would
contend that prioritising public transport represents the
demonstrably wiser strategy, though the case is not entirely
one-sided.

The most compelling reason to favour mass transit lies in a
phenomenon urban economists have long documented as 'induced demand'.
Simply put, whenever additional road capacity is created, latent
travel demand quickly absorbs it, restoring congestion within a
matter of years. Los Angeles offers the textbook illustration:
successive freeway expansions since the 1970s have consistently
failed to reduce commute times, while metropolitan Manila —
which invested comparably in road construction over the same period
— now records some of the longest average journey times globally.
A single metro line, by contrast, can shift up to sixty thousand
passengers per hour, a throughput no motorway can approach.

Environmental considerations reinforce this preference. Electrified
public transport, particularly when paired with renewable generation,
approaches zero-emission operation, whereas private vehicles remain
among the largest single contributors to urban air pollution.
Copenhagen and Zurich, both of which reoriented investment towards
integrated public transport decades ago, now enjoy air quality that
consistently exceeds World Health Organization benchmarks —
outcomes their road-heavy peers have found virtually impossible to
replicate.

That said, road infrastructure retains genuine value for freight
logistics and low-density regions where transit is impractical.
The prudent policy is therefore not to abandon road spending
entirely, but to shift the balance decisively — and, in my view,
irreversibly — towards mass transit.

Intro (2 câu, 50 từ)

Câu 1:

“Few debates in urban policy have proved as enduring — or as consequential — as the question of whether public funds should be channelled towards mass transit systems or towards the continuous expansion of roadways.”🔊🎤🌐

Đắt điểm ở đâu:

• "Few debates… have proved as enduring" — cấu trúc so sánh phủ định + inversion nhẹ = band 8 sophistication
• "as enduring — or as consequential — as" — dấu gạch ngang chèn — thêm nhấn (hiếm ở band 6.5)
• "public funds should be channelled towards" — passive + metaphor "channel" (guide flow) thay "spent on"
• "mass transit systems" — technical term thay "public transport" cho variety

Câu 2:

“Having weighed both arguments, I would contend that prioritising public transport represents the demonstrably wiser strategy, though the case is not entirely one-sided.”🔊🎤🌐

• "Having weighed both arguments," — perfect participle mở đầu = band 8 grammar
• "I would contend" — thay "I think / I believe" — modal + contend (formal)
• "the demonstrably wiser strategy" — adverb + comparative + noun (không viết "the wiser strategy" trần trụi)
• "though the case is not entirely one-sided" — qualification cho quan điểm = nuanced = band 8

Body 1 — Induced demand (95 từ)

“The most compelling reason… lies in a phenomenon urban economists have long documented as 'induced demand'.”🔊🎤🌐

• "lies in a phenomenon [that] urban economists have long documented as…" — reduced relative clause + technical term
• Introducing a named concept ("induced demand" in quotes) = deep domain knowledge

“Simply put, whenever additional road capacity is created, latent travel demand quickly absorbs it, restoring congestion within a matter of years.”🔊🎤🌐

• "Simply put," — signalling paraphrase to non-expert readers (band 8 audience awareness)
• "latent travel demand" — precise economics term
• "restoring congestion within a matter of years" — participle phrase (band 8 structure)

“Los Angeles offers the textbook illustration: successive freeway expansions since the 1970s have consistently failed to reduce commute times…”🔊🎤🌐

• "the textbook illustration" — idiom for "prime example"
• Present perfect ("have consistently failed") to link past→present = accuracy
• "successive freeway expansions" — precision (not "many expansions")

“…while metropolitan Manila — which invested comparably in road construction over the same period — now records some of the longest average journey times globally.”🔊🎤🌐

• "metropolitan Manila" — geographical specificity
• "— which invested comparably… —" dashes for parenthetical relative clause = band 8 punctuation

“A single metro line, by contrast, can shift up to sixty thousand passengers per hour, a throughput no motorway can approach.”🔊🎤🌐

• "a throughput no motorway can approach" — reduced clause equivalent to "a throughput that no motorway can approach" — cleft-like
• "shift" used metaphorically for "transport" — precise & vivid

Body 2 — Environmental (75 từ)

“Environmental considerations reinforce this preference.”🔊🎤🌐

• Short punchy topic sentence — band 8 varies sentence length (not all long)

“Electrified public transport, particularly when paired with renewable generation, approaches zero-emission operation, whereas private vehicles remain among the largest single contributors to urban air pollution.”🔊🎤🌐

• "particularly when paired with" — reduced conditional / temporal clause
• "approaches zero-emission operation" — precise: "approaches" instead of "produces zero" (accurate!)
• "whereas" = contrast subordinator (band 6.5 uses "but")

“Copenhagen and Zurich, both of which reoriented investment towards integrated public transport decades ago, now enjoy air quality that consistently exceeds World Health Organization benchmarks…”🔊🎤🌐

• "both of which" = advanced relative clause with quantifier
• "reoriented investment towards" — collocation "reorient towards"
• "exceeds WHO benchmarks" — measurable specificity

“…outcomes their road-heavy peers have found virtually impossible to replicate.”🔊🎤🌐

• "their road-heavy peers" — coinage (road-heavy = adjective compound)
• "have found virtually impossible to replicate" — sentence-level idiom

Conclusion — Nuanced position (60 từ)

“That said, road infrastructure retains genuine value for freight logistics and low-density regions where transit is impractical.”🔊🎤🌐

• "That said," = concession opener (thừa nhận mặt kia) = band 8 hallmark
• "retains genuine value" — precise adjective
• "freight logistics and low-density regions" — 2 specific cases

“The prudent policy is therefore not to abandon road spending entirely, but to shift the balance decisively — and, in my view, irreversibly — towards mass transit.”🔊🎤🌐

• "not to abandon… but to shift" — parallel construction with "not… but…"
• "— and, in my view, irreversibly —" — dashes chèn opinion cuối câu
• "decisively" + "irreversibly" — cặp adverb mạnh khép bài

Điểm cần nhớ

• Band 8 = đúng + tinh tế — nuanced position, precise word choice, structural variety
• Dùng "That said," / "Having said that," để nhượng bộ nuanced
• Named concepts ("induced demand", "throughput") = show domain knowledge
• Compound adjectives ("road-heavy", "low-density") = precision
• Dashes cho parenthetical chèn thêm nhấn — dùng SỐ ÍT (max 2 lần/bài)
• Đừng cố ép — 1 câu band 8 giữa đoạn band 6.5 gây khiên cưỡng. Đi từng bước: band 6.5 → 7.0 → 7.5 → 8.0
• Bài tiếp theo (P-T2-04) sẽ là Discussion band 8.0 — 2 view cân bằng, quan điểm nuanced hơn
