Post-Modification of Nouns Là Gì?

Định Nghĩa

Post-modification of nouns là cách bổ sung thông tin mô tả, giới hạn hoặc làm rõ nghĩa cho danh từ bằng cách đặt các từ, cụm từ hoặc mệnh đề phía sau danh từ đó. Khác với pre-modification (bổ nghĩa phía trước như “the beautiful house”), post-modification cho phép bạn truyền tải nhiều thông tin phức tạp hơn một cách tự nhiên và học thuật.

Chức năng chính:

• Cung cấp thông tin chi tiết, cụ thể về danh từ mà không làm câu văn trở nên rối rắm
• Tạo sự súc tích trong văn viết học thuật (academic writing)
• Thể hiện khả năng sử dụng ngữ pháp phức tạp – yếu tố quan trọng để đạt band 7+
• Giúp tránh lặp từ và kết nối ý trong câu một cách tự nhiên
• Tăng tính chính xác và độ tin cậy của thông tin

Khi nào dùng trong IELTS:

• Speaking: Khi mô tả người, địa điểm, sự vật (Part 2), hoặc giải thích quan điểm phức tạp (Part 3)
• Writing: Đặc biệt quan trọng trong Writing Task 2 khi phát triển luận điểm, và Task 1 khi mô tả dữ liệu chi tiết
• Giúp đạt tiêu chí “Grammatical Range and Accuracy”: Sử dụng đúng và đa dạng post-modifiers là dấu hiệu của band 7-9

• What subject they taught
• What made them special
• And explain how they influenced you

Sample answer (Band 8.0):

“I’d like to talk about Mrs. Johnson, a teacher who taught me English literature during my final year of high school. She was someone with an exceptional ability to make classic texts accessible and engaging.

The characteristic that made her stand out was her teaching method. She would encourage us to explore themes relevant to our own lives rather than simply memorizing facts required for exams.

One particular lesson that left a lasting impression on me was when we studied Shakespeare. Instead of the traditional approach, she organized discussions allowing us to debate different interpretations. This experience of analyzing literature critically helped me develop skills that I still use today in my academic work.

Mrs. Johnson, a mentor who genuinely cared about her students’ growth, inspired me to pursue a degree in education. Her influence extends beyond academics; she taught me the importance of passion and creativity in teaching, qualities that I hope to emulate in my future career.”

Additionally, the integration of technology, something that was virtually non-existent when I was in primary school, has revolutionized the learning experience. Students now have access to online resources providing diverse perspectives on any topic.

However, challenges remain, particularly for students living in rural areas, who often lack the infrastructure needed to fully benefit from these technological advances. This is an issue requiring urgent attention from policymakers.”

Q: “What makes a good teacher?”

A (Band 8-9): “I believe a good teacher possesses several key qualities. First and foremost is the ability to inspire curiosity, a trait that cannot be taught through textbooks. Effective teachers are individuals who understand that education extends beyond exam results.

They also demonstrate patience, especially when working with students struggling with difficult concepts. Moreover, adaptability is crucial – teachers need the flexibility to adjust their methods for learners with different learning styles.

Finally, I’d say passion is essential. Students can easily detect whether their teacher genuinely loves their subject, and this enthusiasm, combined with expertise, creates an environment conducive to real learning.”

Opinion Essay

Topic: Some people believe that universities should only offer subjects that are useful for future jobs. Others believe universities should provide knowledge for its own sake. Discuss both views and give your opinion.

Introduction (Band 8.0):

“The purpose of higher education has become a topic generating considerable debate. While some argue that universities should focus solely on vocational training, courses directly relevant to employment, others contend that the pursuit of knowledge, regardless of its practical application, remains the primary academic mission. This essay will examine both perspectives before concluding that a balanced approach, one that combines theoretical learning with practical skills, is most beneficial.”

→ Phân tích:

• “generating considerable debate” (present participle – mô tả topic)
• “courses directly relevant to employment” (appositive + past participle)
• “regardless of its practical application” (prepositional phrase)
• “one that combines…” (appositive + relative clause)

Body Paragraph 1 (Band 8.0):

“Proponents of vocational education advance several compelling arguments. Firstly, in an increasingly competitive job market, graduates equipped with practical skills have a distinct advantage over those possessing only theoretical knowledge. Engineering and business programs, fields that emphasize hands-on experience, typically produce graduates who find employment more readily. Furthermore, the substantial investment required for university education should yield tangible returns, a benefit that practical training is more likely to deliver. From this perspective, courses lacking clear career pathways represent an inefficient use of educational resources.”

→ Phân tích 7 post-modifiers:

1. “equipped with practical skills” (past participle phrase)
2. “possessing only theoretical knowledge” (present participle phrase)
3. “fields that emphasize…” (appositive + relative clause)
4. “who find employment…” (relative clause)
5. “required for university education” (past participle phrase)
6. “a benefit that practical training…” (appositive + relative clause)
7. “lacking clear career pathways” (present participle phrase)

Body Paragraph 2 (Band 8.5):

“However, the counter-argument, that education should transcend purely economic considerations, merits serious attention. Universities, institutions originally designed to preserve and advance human knowledge, serve a function extending beyond workforce preparation. Subjects traditionally deemed ‘impractical’, such as philosophy and classical literature, develop critical thinking and ethical reasoning, skills essential for informed citizenship. Moreover, many significant innovations have emerged from theoretical research conducted without immediate commercial objectives. The internet, a technology now fundamental to modern life, originated from academic research motivated purely by intellectual curiosity.

Problem-Solution Essay

Topic: In many countries, the level of crime is increasing and crimes are becoming more violent. Why do you think this is and what can be done about it?

Sample Body Paragraph (Band 8.0):

“Several factors contributing to rising crime rates warrant examination. Economic inequality, a problem affecting numerous developing nations, creates desperation that can drive individuals toward criminal behavior. Young people growing up in impoverished neighborhoods often lack access to quality education and legitimate employment opportunities, resources essential for social mobility. Additionally, the breakdown of traditional family structures, combined with inadequate community support systems, has resulted in many youths lacking positive role models and guidance. The influence of violent media, content readily accessible through digital platforms, may also desensitize individuals to aggressive behavior, though this remains a contentious issue among researchers.

To address these challenges, governments must implement comprehensive strategies. Investment in education and job training programs targeting disadvantaged communities can provide alternatives to criminal activity. Community policing initiatives, approaches that build trust between law enforcement and residents, have proven effective in areas previously plagued by high crime rates. Furthermore, rehabilitation programs focusing on skill development and psychological support offer better outcomes than purely punitive measures, especially for first-time offenders seeking to reintegrate into society.”

Advantage-Disadvantage Essay

Topic: More and more people are working from home. What are the advantages and disadvantages of this trend?

Sample paragraph (Band 8.0):

“Remote work offers several significant benefits. Employees working from home enjoy greater flexibility, a factor that improves work-life balance and job satisfaction. Time previously spent commuting can be redirected toward productive activities or personal pursuits. Companies adopting remote work policies benefit from reduced overhead costs, particularly expenses related to office space and utilities. Additionally, the ability to hire talent from anywhere expands the pool of potential employees, enabling organizations to access skills that might be geographically limited.

However, challenges associated with remote work cannot be overlooked. The isolation experienced by many home-based workers can negatively impact mental health and team cohesion. Communication difficulties, issues that rarely arise in face-to-face settings, may lead to misunderstandings affecting project outcomes. Furthermore, the blurred boundaries between work and personal life, a problem common among remote workers, can result in longer working hours and increased stress, consequences that ultimately undermine the initial benefits.”

So Sánh Với Cấu Trúc Tương Tự

Pre-modification vs Post-modification

Tiêu chí	Pre-modification	Post-modification
Vị trí	Trước danh từ	Sau danh từ
Thành phần	Adjectives, determiners, nouns	Clauses, phrases, prepositional phrases
Độ phức tạp	Giới hạn (1-3 từ thường dùng)	Không giới hạn, có thể rất phức tạp
Thông tin	Cơ bản, ngắn gọn	Chi tiết, cụ thể, nhiều layer
Ví dụ	“The beautiful old Victorian house”	“The house which was built in the Victorian era“
IELTS usage	Band 6-7 (đủ dùng)	Band 7-9 (cần thiết để đạt điểm cao)
Academic style	Informal hơn	Formal, academic

Khi nào dùng pre-modification:

• Mô tả đơn giản, rõ ràng
• Speaking Part 1 (câu trả lời ngắn)
• Khi cần súc tích và không cần chi tiết
• Ví dụ: “modern technology”, “environmental problems”, “economic growth”

Khi nào dùng post-modification:

• Cần cung cấp thông tin cụ thể, chi tiết
• Writing Task 2 (phát triển luận điểm)
• Speaking Part 2 & 3 (mô tả chi tiết, giải thích phức tạp)
• Khi muốn thể hiện grammatical range
• Ví dụ: “technology that has transformed modern life“, “problems facing developing nations“, “growth driven by technological innovation“

Combining both cho Band 8+:

“The significant environmental challenges faced by coastal cities in Southeast Asia require urgent attention.”

→ Pre-modifiers: “significant”, “environmental”, “coastal”
→ Post-modifiers: “faced by coastal cities”, “in Southeast Asia”
→ Effect: Precise và information-rich

Active vs Passive Participles

Active Participle (V-ing)	Passive Participle (V3/ed)
Ý nghĩa: Chủ động, đang diễn ra	Ý nghĩa: Bị động, đã hoàn thành
Khi dùng: Danh từ thực hiện hành động	Khi dùng: Danh từ nhận hành động
Ví dụ 1: “Students studying abroad” (Sinh viên đang du học – chủ động)	“Students educated abroad” (Sinh viên được giáo dục ở nước ngoài – bị động)
Ví dụ 2: “Issues affecting youth” (Vấn đề ảnh hưởng đến giới trẻ)	“Youth affected by poverty” (Giới trẻ bị ảnh hưởng bởi nghèo đói)
Ví dụ 3: “Research examining the effects“	“Effects examined in the research“
IELTS context: Describing ongoing actions, trends	IELTS context: Describing completed actions, results

Common mistakes Vietnamese learners make:

❌ SAI: “People educated in rural schools” (khi muốn nói họ đang được giáo dục)
✅ ĐÚNG: “People being educated in rural schools” hoặc “People studying in rural schools“

❌ SAI: “The data collected shows…” (khi muốn nói dữ liệu đang được thu thập)
✅ ĐÚNG: “The data being collected shows…” (nếu đang thu thập) hoặc “The data collected shows…” (nếu đã thu thập xong)

Relative Clauses vs Participle Phrases

Khi nào dùng relative clauses:

✅ Cần động từ có thì cụ thể (past, future, perfect, etc.)
✅ Có modal verbs (can, must, should, etc.)
✅ Cần phủ định (not)
✅ Có object hoặc complement phức tạp

Ví dụ:

• “Students who will graduate next year face uncertainties.”
• “Problems that cannot be solved easily require innovative thinking.”
• “People who have never experienced poverty may not understand its impact.”

Khi nào dùng participle phrases:

✅ Muốn câu văn súc tích hơn
✅ Academic writing style (formal hơn)
✅ Khi thì động từ là simple present/past
✅ Tránh lặp lại relative pronouns nhiều lần

Ví dụ:

• “Students graduating next year” (thay vì “who will graduate”)
• “Issues requiring immediate attention” (thay vì “that require”)
• “Data showing significant trends” (thay vì “which shows”)

So sánh trực tiếp:

Relative Clause (dài hơn)	Participle Phrase (ngắn gọn hơn)
“People who live in cities”	“People living in cities”
“The report which was published last year”	“The report published last year”
“Students who are studying abroad”	“Students studying abroad”
“Factors that contribute to success”	“Factors contributing to success”

Khi nào KHÔNG thể thay thế:

❌ Không thể: “Students who can speak three languages”
(Không thể → “Students speaking three languages” – sai nghĩa)

❌ Không thể: “Countries that might face economic crisis”
(Không thể dùng participle với modal verb)

❌ Không thể: “People who don’t have access to education”
(Không thể dùng participle với phủ định đơn giản)

Lỗi Thường Gặp & Cách Sửa

Lỗi 1: Sử dụng sai thì động từ trong relative clause

❌ SAI:
“Students who studies abroad gain independence.”

✅ ĐÚNG:
“Students who study abroad gain independence.”

Giải thích:
Động từ trong relative clause phải chia theo danh từ mà relative pronoun thay thế. Ở đây “who” thay cho “students” (số nhiều) nên động từ phải là “study” không phải “studies”.

Quy tắc:

• “Students (plural) who study…”
• “A student (singular) who studies…”
• “The data (uncountable) which shows…”
• “Facts (plural) which show…”

Lưu ý đặc biệt cho học viên Việt:
Trong tiếng Việt không có chia động từ theo số nên đây là lỗi rất phổ biến. Hãy luôn xác định danh từ mà relative pronoun đang thay thế trước khi chia động từ.

Bài tập sửa lỗi:

❌ “The person who work here is my colleague.”
✅ “The person who works here is my colleague.”

❌ “Companies which provides training benefit from higher productivity.”
✅ “Companies which provide training benefit from higher productivity.”

Lỗi 2: Nhầm lẫn giữa present và past participle

❌ SAI:
“People educated in urban schools often have better opportunities.” (khi muốn nói đang được giáo dục)

✅ ĐÚNG:
“People being educated in urban schools often have better opportunities.”

HOẶC

“People studying in urban schools often have better opportunities.”

Giải thích:

• Past participle (V3/ed) dùng khi hành động đã hoàn thành hoặc mang nghĩa bị động
• Present participle (V-ing) dùng khi hành động đang diễn ra hoặc mang nghĩa chủ động

So sánh:

• “People educated abroad” = Người đã được giáo dục ở nước ngoài (đã hoàn thành)
• “People studying abroad” = Người đang du học (đang diễn ra)

Lỗi phổ biến của học viên Việt:

❌ “Issues affecting by climate change”
✅ “Issues affected by climate change”
(Issues bị ảnh hưởng → passive → past participle)

❌ “Students interested in science”
✅ ĐÚNG (interested là tính từ dạng past participle – mang nghĩa bị động “bị hứng thú”)

❌ “The data collecting by researchers”
✅ “The data collected by researchers”
(Data được thu thập → passive → past participle)

Trick để nhớ:

• Nếu có “by + agent” → dùng past participle
• Nếu danh từ “thực hiện” hành động → present participle
• Nếu danh từ “nhận” hành động → past participle

Lỗi 3: Thiếu relative pronoun khi cần thiết

❌ SAI:
“The book I bought yesterday is very interesting.”

✅ ĐÚNG (Formal – IELTS Writing):
“The book which/that I bought yesterday is very interesting.”

Giải thích:
Trong văn nói informal hoặc văn viết casual, ta có thể lược bỏ relative pronoun khi nó làm object. Tuy nhiên, trong IELTS Writing (đặc biệt Task 2) và Speaking Part 2-3, việc giữ relative pronoun thể hiện academic style và grammatical range tốt hơn.

Khi nào có thể lược bỏ (optional):
✅ Khi relative pronoun làm OBJECT:

• “The person (who/whom/that) I met was helpful.” → có thể bỏ
• “The book (which/that) you recommended is excellent.” → có thể bỏ

Khi nào KHÔNG thể lược bỏ:
❌ Khi relative pronoun làm SUBJECT:

• “People who live in cities…” → KHÔNG thể bỏ “who”
• “The report which shows data…” → KHÔNG thể bỏ “which”

Khuyến nghị cho IELTS:
Trong Writing Task 2 và Speaking Part 2-3, nên GIỮ relative pronoun để:

• Thể hiện formal style
• Tránh ambiguity
• Demonstrate grammatical range

Ví dụ trong IELTS Writing:

❌ Less formal: “The advantages technology brings are significant.”
✅ More formal: “The advantages that/which technology brings are significant.”

❌ Less formal: “The person I admire most is my teacher.”
✅ More formal: “The person whom I admire most is my teacher.”

Lỗi 4: Dùng sai giới từ trong prepositional phrases

❌ SAI:
“The increase on pollution is alarming.”

✅ ĐÚNG:
“The increase in pollution is alarming.”

Giải thích:
Mỗi danh từ thường đi với giới từ cố định. Học viên Việt Nam thường dịch trực tiếp từ tiếng Việt hoặc nhầm lẫn giữa các giới từ.

Các cặp danh từ + giới từ phổ biến trong IELTS:

Với “in”:

• increase/rise/growth in (something): “a rise in unemployment”
• decrease/decline in: “a decline in birth rates”
• change in: “changes in lifestyle”
• expert in: “experts in education”
• interest in: “interest in technology”

Với “of”:

• cost of: “the cost of living”
• impact/effect of: “the impact of globalization”
• cause of: “the cause of the problem”
• level of: “the level of pollution”
• rate of: “the rate of economic growth”

Với “on”:

• effect on: “the effect on society”
• impact on: “impact on the environment”
• research on: “research on climate change”
• tax on: “tax on luxury goods”
• emphasis on: “emphasis on quality”

Với “to”:

• solution to: “solutions to the problem”
• answer to: “the answer to this question”
• approach to: “a new approach to teaching”
• attitude to/toward: “attitudes to work”
• access to: “access to education”

Với “for”:

• demand for: “the demand for skilled workers”
• need for: “the need for reform”
• reason for: “reasons for this trend”
• responsibility for: “responsibility for the environment”

Với “with”:

• relationship with: “relationships with colleagues”
• problem with: “problems with the system”
• issue with: “issues with quality”

Lỗi thường gặp:

❌ “The solution of the problem”
✅ “The solution to the problem”

❌ “The impact for society”
✅ “The impact on society”

❌ “Research about climate”
✅ “Research on climate” (formal) hoặc “Research about climate” (informal)

❌ “The cost for education”
✅ “The cost of education”

Lỗi 5: Đặt sai vị trí của post-modifier gây khó hiểu

❌ SAI (Ambiguous):
“I met a teacher yesterday who taught me English.”

✅ ĐÚNG:
“Yesterday, I met a teacher who taught me English.”

HOẶC

“I met a teacher who taught me English yesterday.”

Giải thích:
Trong câu sai, không rõ “yesterday” thuộc về “met” hay “taught”. Post-modifier nên đặt ngay sau danh từ nó bổ nghĩa để tránh nhầm lẫn.

Quy tắc vị trí:

1. Post-modifier phải đặt NGAY SAU danh từ nó bổ nghĩa
2. Các trạng từ thời gian/địa điểm của main clause nên đặt đầu hoặc cuối câu

Ví dụ minh họa:

❌ CONFUSING: “She bought a book at the store which was very expensive.”
(Cái gì expensive? The book hay the store?)

✅ CLEAR: “She bought a book which was very expensive at the store.”
(Rõ ràng là book expensive)

❌ CONFUSING: “The company hired employees last year who had international experience.”

✅ CLEAR: “Last year, the company hired employees who had international experience.”

Lỗi phức tạp hơn:

❌ “Students can access resources online which are free.”
(Resources online? Hay resources which are free?)

✅ “Students can access online resources which are free.”
HOẶC
✅ “Students can access resources which are free online.”

Đặc biệt lưu ý trong IELTS Writing:

❌ “The graph shows the number of people in three countries who used smartphones.”
(Hơi confusing – in three countries hay people who used?)

✅ “The graph shows the number of people who used smartphones in three countries.”
(Rõ ràng hơn)

Practice để tránh lỗi này:

Luôn tự hỏi: “Post-modifier này đang bổ nghĩa cho danh từ nào?” và đặt nó ngay sau danh từ đó.

Lỗi 6: Lạm dụng “that” thay vì đa dạng relative pronouns

❌ Không đa dạng (Band 6-7):
“People that live in cities often face problems that relate to pollution that is caused by vehicles that emit harmful gases.”

✅ Đa dạng hơn (Band 8+):
“People who live in cities often face problems related to pollution caused by vehicles emitting harmful gases.”

Giải thích:
Mặc dù “that” có thể dùng cho cả người và vật, việc lạm dụng nó khiến câu văn đơn điệu và không thể hiện grammatical range. Band 8+ cần đa dạng:

Đa dạng cách diễn đạt:

1. Dùng who cho người: “People who…” thay vì “People that…”
2. Dùng which cho vật: “Technology which…” thay vì “Technology that…”
3. Dùng whose cho sở hữu: “Students whose parents…” thay vì “Students that their parents…”
4. Chuyển sang participle phrases: “problems related to” thay vì “problems that relate to”
5. Dùng where cho địa điểm: “Countries where poverty…” thay vì “Countries that poverty…”

So sánh Band 6 vs Band 8:

Band 6 version:
“The city that I visited that has monuments that date back to ancient times that attracts tourists that come from all over the world.”

Band 8 version:
“The city which I visited has monuments dating back to ancient times and attracts tourists from all over the world.”

Lưu ý:

• Trong non-defining relative clauses (có dấu phẩy), KHÔNG dùng “that”
  • ❌ “My teacher, that is very experienced, helped me a lot.”
  • ✅ “My teacher, who is very experienced, helped me a lot.”

Lỗi 7: Không nhất quán giữa defining và non-defining relative clauses

❌ SAI:
“My brother who lives in London is a doctor.” (nếu bạn chỉ có 1 anh/em trai)

✅ ĐÚNG:
“My brother, who lives in London, is a doctor.”

Giải thích sự khác biệt:

A. Defining Relative Clause (KHÔNG có dấu phẩy):

• Thông tin thiết yếu để xác định danh từ đang nói đến
• Không thể bỏ đi
• Dùng khi có nhiều người/vật cần phân biệt

Ví dụ: “My brother who lives in London is a doctor.”
→ Nghĩa: Tôi có nhiều anh/em trai, người sống ở London là bác sĩ (ngụ ý có anh/em trai khác không sống ở London)

B. Non-defining Relative Clause (CÓ dấu phẩy):

• Thông tin bổ sung, không thiết yếu
• Có thể bỏ đi mà câu vẫn rõ nghĩa
• Dùng khi danh từ đã xác định rõ

Ví dụ: “My brother, who lives in London, is a doctor.”
→ Nghĩa: Tôi chỉ có 1 anh/em trai, thông tin thêm là anh ấy sống ở London

Cách phân biệt trong IELTS:

Dùng DEFINING (không dấu phẩy) khi:

✅ “Students who study hard usually succeed.” (Không phải tất cả students, chỉ những người study hard)

✅ “Countries that invest in education develop faster.” (Phân biệt với countries không invest)

✅ “The book which won the prize is excellent.” (Chỉ cuốn book nào win prize, không phải book khác)

Dùng NON-DEFINING (có dấu phẩy) khi:

✅ “Tokyo, which is the capital of Japan, is very crowded.” (Tokyo đã xác định rõ, thông tin thêm về nó)

✅ “My teacher, who has 20 years of experience, is very knowledgeable.” (My teacher = specific person)

✅ “The report, which was published last month, shows significant findings.” (The report đã xác định cụ thể)

Lỗi thường gặp của học viên Việt Nam:

❌ “Hanoi which is the capital of Vietnam is my hometown.”
✅ “Hanoi, which is the capital of Vietnam, is my hometown.”

❌ “Professor Smith, who teaches mathematics is very strict.”
✅ “Professor Smith, who teaches mathematics, is very strict.”

❌ “The Internet, that has changed our lives, was invented in the 20th century.”
✅ “The Internet, which has changed our lives, was invented in the 20th century.”
(Remember: KHÔNG dùng “that” trong non-defining clauses)

Trick để nhớ:

• Nếu bỏ relative clause đi mà câu vẫn rõ nghĩa → NON-DEFINING → cần dấu phẩy
• Nếu bỏ relative clause đi thì không biết đang nói về cái gì → DEFINING → không dấu phẩy

Cách Tự Đánh Giá

Checklist sau khi hoàn thành bài tập:

Về số lượng:

• [ ] Đã sử dụng ít nhất 5 post-modifiers trong Speaking Part 2 (2 phút)?
• [ ] Có 8-10 post-modifiers trong mỗi body paragraph của Writing Task 2?
• [ ] Đã đa dạng hóa 5 loại post-modifiers khác nhau?

Về chất lượng:

• [ ] Tất cả post-modifiers đều đặt đúng vị trí (ngay sau danh từ)?
• [ ] Động từ trong relative clauses chia đúng theo danh từ?
• [ ] Participles dùng đúng active/passive?
• [ ] Giới từ trong prepositional phrases chính xác?
• [ ] Có sử dụng dấu phẩy đúng cho non-defining clauses?

Về tính tự nhiên:

• [ ] Post-modifiers giúp câu văn academic hơn, không làm câu quá dài khó hiểu?
• [ ] Có kết hợp post-modifiers với các cấu trúc nâng cao khác?
• [ ] Collocations với post-modifiers có đúng không?

Next steps để tiến bộ:

1. Record và transcribe: Ghi âm Speaking responses, sau đó transcribe và highlight tất cả post-modifiers. Phân tích xem đã đa dạng chưa.

2. Peer review: Trao đổi bài Writing với bạn học, đánh dấu post-modifiers và kiểm tra lỗi lẫn nhau.

3. Analyze model answers: Đọc Cambridge IELTS band 8-9 answers, highlight tất cả post-modifiers và học cách native speakers sử dụng.

4. Gradual complexity: Tuần 1: Chỉ focus vào 1-2 loại. Tuần 2-3: Kết hợp 3-4 loại. Tuần 4+: Sử dụng linh hoạt tất cả.

5. Daily practice: Mỗi ngày viết 5 câu có post-modifiers về chủ đề IELTS bất kỳ. Sau 30 ngày, bạn sẽ thấy sự khác biệt rõ rệt.

Lời khuyên cuối cùng:

Đừng cố gắng sử dụng quá nhiều post-modifiers trong một câu nếu chưa thành thạo. Hãy bắt đầu với câu đơn giản, sau đó dần dần tăng độ phức tạp. Mục tiêu là accuracy (chính xác) trước, complexity (phức tạp) sau. Band 7 với post-modifiers đơn giản nhưng chính xác vẫn tốt hơn Band 6 với cấu trúc phức tạp nhưng đầy lỗi sai.

Chúc bạn học tập hiệu quả và đạt band điểm mong muốn trong kỳ thi IELTS!
