Tóm tắt

Band 7 yêu cầu "a variety of complex structures with some flexibility and accuracy." Band 8 yêu cầu "a wide range of structures used with flexibility and accuracy." Bài viết này giới thiệu các cấu trúc nâng cao giúp nâng điểm Grammar từ 6.5 lên 7+ — những cấu trúc hiếm gặp trong bài thí sinh trung bình, nhưng tự nhiên với người dùng tiếng Anh học thuật.

Tại sao quan trọng

Thí sinh Band 6-6.5 thường biết ngữ pháp cơ bản nhưng thiếu grammatical flexibility — khả năng chọn cấu trúc phù hợp với mục đích giao tiếp (nhấn mạnh, tạo khoảng cách học thuật, thể hiện quan hệ logic tinh tế). Các cấu trúc dưới đây giải quyết đúng điều này.

Phần 1: Inversion — Đảo ngữ để nhấn mạnh

Đảo ngữ là đưa phần phụ (thường là trạng từ phủ định hoặc hạn chế) lên đầu câu, kéo trợ động từ lên trước chủ ngữ. Cấu trúc này rất phổ biến trong văn học thuật tiếng Anh.

Inversion với trạng từ phủ định

Never / Rarely / Seldom / Hardly / Scarcely / No sooner + aux + S + V
  • Never before has the world faced such a complex environmental crisis. (= The world has never before faced...)
  • Rarely do governments act quickly enough to prevent ecological damage. (= Governments rarely act...)
  • Seldom is a single policy sufficient to address poverty. (= A single policy is seldom sufficient...)
  • Hardly had the negotiations begun when disagreements emerged. (= Disagreements emerged almost as soon as the negotiations began.)

Inversion với "Only"

Only + adverbial phrase + aux + S + V
  • Only by investing in education can governments hope to reduce inequality long-term. (= Governments can only hope to reduce inequality by investing in education.)
  • Only when we understand the root causes can we develop effective solutions.
  • Only after years of research was an effective vaccine developed.

Inversion với "Not only...but also"

Not only + aux + S + V, but S + also + V
  • Not only does technology create new jobs, but it also transforms existing industries.
  • Not only has the population grown rapidly, but infrastructure has also failed to keep pace.

Inversion trong câu điều kiện trang trọng (không dùng "if")

Were + S + to + V / Had + S + V3 / Should + S + V (formal)
  • Were the government to reduce taxes, consumer spending would increase. (= If the government were to reduce taxes...)
  • Had stricter policies been introduced earlier, the environmental damage would have been far less severe. (= If stricter policies had been introduced...)
  • Should any problems arise, the team is ready to respond immediately. (= If any problems arise...)

Khi nào dùng: Chỉ dùng inversion trong Writing (trang trọng). Trong Speaking, chỉ dùng ở Band 8+ khi nói rất tự tin. Không nên cố nhét inversion vào Speaking nếu chưa quen.

Phần 2: Cleft Sentences — Câu chẻ để nhấn mạnh

Cleft sentences chia câu thành hai phần để nhấn mạnh một yếu tố cụ thể.

It-cleft

It is/was + [phần được nhấn mạnh] + that/who + phần còn lại
  • It is education that offers the most sustainable path out of poverty. (nhấn mạnh "education" thay vì nói "Education offers...")
  • It was the 2008 financial crisis that exposed the vulnerability of deregulated banking systems.
  • It is governments, not individuals, that bear the primary responsibility for addressing climate change.

What-cleft

What + S + V + is/was + [phần được nhấn mạnh]
  • What many people fail to realise is that short-term solutions often create long-term problems.
  • What the data clearly shows is a steady decline in biodiversity over the past three decades.
  • What young people need is not just better job opportunities, but also affordable housing.
  • What makes this approach effective is its focus on prevention rather than cure.

Cleft với "The reason"

The reason (why) + S + V + is that + clause
  • The reason why so many young people choose to emigrate is that opportunities in their home countries are limited.
  • The primary reason urban poverty persists is a lack of access to quality education and healthcare.

Phần 3: Complex Noun Phrases — Cụm danh từ phức tạp

Thay vì dùng nhiều câu ngắn, gộp ý vào một cụm danh từ phức tạp — đặc trưng của văn học thuật.

Danh từ + of-phrase + relative clause

  • The rapid growth of urban populations, which shows no sign of slowing, has placed enormous strain on infrastructure.
  • The failure of governments to address inequality over the past decade has fuelled social unrest.

Gerund phrase làm chủ ngữ

V-ing + ... + is/has
  • Reducing carbon emissions while maintaining economic growth is one of the central challenges of our time.
  • Implementing effective public health policies requires both political will and adequate funding.
  • Relying solely on market forces to regulate environmental standards has proven insufficient.

Abstract noun + modifier

Thay vì dùng clause, dùng noun phrase để viết gọn và học thuật hơn:

Clause (thông thường) Noun phrase (học thuật)
Because people are migrating to cities The migration of people to cities
When technology advances rapidly The rapid advancement of technology
The fact that inequality has increased The growing inequality / The rise in inequality
Because governments failed to act The failure of governments to act

Phần 4: Mixed Conditionals — Điều kiện hỗn hợp

Mixed conditionals kết hợp thì của hai loại điều kiện khác nhau — thể hiện mối quan hệ nhân quả phức tạp giữa quá khứ và hiện tại.

Type 3 if-clause + Type 2 main clause (Quá khứ → Hiện tại)

If + Past Perfect, would + V (bare)

Dùng khi: điều kiện trong quá khứ ảnh hưởng đến tình trạng hiện tại.

  • If governments had invested in renewable energy thirty years ago, we would not be facing such a severe energy crisis now.
  • If she had chosen a different career path, she would be in a very different position today.
  • If the global community had acted sooner on climate change, temperatures would not be rising so rapidly.

Type 2 if-clause + Type 3 main clause (Hiện tại → Quá khứ)

If + Past Simple (were), would have + V3

Dùng khi: tính chất hiện tại ảnh hưởng đến kết quả quá khứ.

  • If the healthcare system were better funded, the pandemic response would have been far more effective.
  • If governments were more accountable to citizens, the corruption scandal would never have occurred.

Phần 5: Advanced Passive Constructions

Passive reporting structures (rất phổ biến trong học thuật)

It is + V3 (that clause)      →     tạo khoảng cách học thuật
S + is + V3 (to + V)          →     cách khác của reporting passive
Cụ thể Ví dụ
It is argued that It is argued that economic growth alone cannot solve inequality.
It is widely believed that It is widely believed that early intervention improves long-term outcomes.
It has been shown that Research has shown that exercise improves cognitive function.
S + is said to + V The gap between rich and poor is said to be widening.
S + is thought to + V The policy is thought to have had limited success.
S + is considered to + V Access to clean water is considered to be a fundamental human right.
S + is known to + V Processed food is known to contribute to obesity.

Passive infinitive và passive gerund

Passive infinitive: to be + V3
Passive gerund: being + V3
  • The new regulations are expected to be implemented by the end of the year. (passive infinitive)
  • She resented being treated as if she were inexperienced. (passive gerund after resent)
  • The report remains to be published, pending final approval. (remains to be + V3)

Phần 6: Hedging Language — Diễn đạt thận trọng

Văn học thuật Band 7+ không nói tuyệt đối. Hedging thể hiện sự tinh tế học thuật.

Hedging mức độ khẳng định

Mức độ Cụm từ
Rất chắc clearly, evidently, undeniably, it is certain that
Khá chắc it is likely that, it would seem that, the evidence suggests
Trung bình it is possible that, it may be the case that, arguably
Thận trọng it might be argued that, one could suggest, there is a possibility
Rất thận trọng it is not entirely clear whether, the evidence is inconclusive

Hedging động từ (epistemic modals + reporting verbs)

  • Technology appears to be transforming the nature of work.
  • The data suggests that the trend will continue.
  • This approach tends to produce better outcomes in the long term.
  • The results would indicate a strong correlation between income and health outcomes.

Hedging phạm vi (scope limitation)

  • In many cases, urban living leads to increased stress.
  • To a large extent, success depends on early education.
  • Under certain conditions, the policy may prove effective.
  • For the most part, renewable energy has proven reliable.
  • This is true particularly in developing economies.

Phần 7: Participle Clauses — Mệnh đề phân từ

Mệnh đề phân từ giúp viết câu phức tạp một cách gọn gàng — đặc trưng của văn học thuật chuyên nghiệp.

V-ing clause (cùng chủ ngữ, đồng thời hoặc nguyên nhân)

V-ing + ..., S + V    (chủ ngữ của hai mệnh đề phải giống nhau)
  • Recognising the severity of the crisis, the government announced emergency measures. (= Because the government recognised... / The government, which recognised...)
  • Having lived abroad for several years, she developed a nuanced understanding of different cultures. (= Because she had lived abroad... — dùng "having + V3" cho hành động trước)

V3 clause (bị động)

V3 + ..., S + V
  • Located in the heart of Southeast Asia, Singapore has developed into a major financial hub.
  • Designed to reduce emissions, the new vehicles have exceeded expectations.
  • Faced with rising unemployment, governments must consider alternative economic strategies.

Absolute clause (chủ ngữ của mệnh đề phân từ khác chủ ngữ chính)

Noun + V-ing/V3, S + V
  • The population ageing rapidly, governments must rethink pension systems.
  • All things considered, the benefits of globalisation outweigh the drawbacks.
  • The data having been collected, researchers could begin their analysis.

Phần 8: Ứng dụng vào Task 2 — Câu mẫu Band 7+

Introduction — đa dạng cách mở bài

Cleft sentence: - It is the question of how to balance economic growth with environmental sustainability that lies at the heart of this debate.

Inversion: - Rarely has a generation faced the combination of challenges — technological disruption, climate change, and economic inequality — that confronts young people today.

Gerund phrase làm chủ ngữ: - Determining the most effective approach to reducing poverty requires an understanding of both structural and individual factors.

Body paragraph — đa dạng cấu trúc

"Not only does urbanisation create economic opportunities, but it also places enormous pressure on infrastructure and housing. What is particularly concerning is the rate at which rural communities are being depopulated, which risks undermining agricultural productivity. Were governments to invest more strategically in rural development, it is possible that migration flows would be significantly reduced. Having recognised this, several countries have begun implementing incentive programmes — a development that many experts consider to have been long overdue."

Các cấu trúc trong đoạn này: Not only...but also (inversion), what-cleft, non-defining relative clause, conditional inversion (were to), hedging (it is possible that), participle clause (having recognised), it-cleft (a development that), passive + perfect infinitive (to have been).

Conclusion — cấu trúc đa dạng

Mixed conditional: - Had more attention been paid to these warning signs decades ago, the current situation would arguably be far less severe.

Gerund + noun phrase: - Addressing these interconnected challenges demands not only political will but also a fundamental shift in how societies value long-term sustainability over short-term gain.

Lỗi thường gặp khi dùng cấu trúc nâng cao

Lỗi 1: Inversion không đúng ngữ cảnh

Inversion cần trợ động từ — không phải đảo vị trí động từ chính: - ❌ Never the government acts quickly enough. - ✅ Never does the government act quickly enough.

Lỗi 2: Cleft sentence sai cấu trúc

  • ❌ It is the education that offers a path out of poverty.
  • ✅ It is education that offers a path out of poverty. (không có "the" nếu nói chung)

Lỗi 3: Participle clause sai chủ ngữ

Chủ ngữ của participle clause phải giống chủ ngữ của mệnh đề chính: - ❌ Walking down the street, the buildings were very tall. (ai đang đi? Không phải "the buildings") - ✅ Walking down the street, I noticed that the buildings were very tall.

Lỗi 4: Cố nhét cấu trúc không tự nhiên

Cấu trúc nâng cao phải phục vụ ý nghĩa — không phải thể hiện ngữ pháp. Nếu inversion làm câu nghe gượng gạo, dùng cấu trúc thường vẫn tốt hơn.
