Topic thường gặp: Hometown changes, Daily routine, Technology use, Lifestyle changes

Ví dụ câu hỏi & trả lời:

Q: “Has your hometown changed much?”

A: “Yes, definitely. My hometown is developing faster and faster. The more the city expands, the more modern facilities we have. However, I’ve noticed that the bigger it becomes, the less peaceful the atmosphere is. There are more and more shopping malls and office buildings being constructed every year.”

• How you learned it
• How long it took
• And explain how this skill has helped you

Sample answer (excerpt):

“I’d like to talk about photography, which I’ve been learning for the past three years. When I first started, everything seemed overwhelming. However, I discovered that the more I practiced, the more confident I became with my camera.

Initially, I could only take basic photos, but as I learned more and more techniques, my work improved significantly. I spent hours watching tutorials and experimenting with different settings. The harder I worked on understanding lighting and composition, the better quality my photos turned out to be.

What’s interesting is that my passion for photography grew proportionally with my skills – the more skilled I became, the more interested I was in exploring different styles. Now I find that the more time I invest in this hobby, the more rewarding it feels. My Instagram following has been growing larger and larger, which motivates me to keep improving…”

Part 3 – Discussion:

Topic: Technology and Society

Q: “How has technology changed the way people communicate?”

A: “Technology has revolutionized communication in remarkable ways. I think the more advanced technology becomes, the more convenient communication gets. We can now connect with people instantly across the globe. However, there’s a concerning trend – the more we rely on digital communication, the less we engage in face-to-face interactions.

I’ve noticed that people are becoming more and more dependent on messaging apps and social media. Paradoxically, the more connected we are digitally, the more isolated some people feel emotionally. This is particularly true for the younger generation who are spending more and more time online.

On the positive side, the easier it becomes to communicate across borders, the more opportunities there are for international collaboration and cultural exchange. But we need to strike a balance, because the further we move towards digital communication, the more important it becomes to preserve genuine human connections.”

Các ví dụ áp dụng Double Comparatives trong IELTS Speaking Part 2 và Part 3 với phân tích chi tiết

Writing Task 1

Khi nào dùng:

• Mô tả xu hướng tăng/giảm liên tục trong line graphs
• So sánh hai xu hướng có mối tương quan trong bar charts hoặc line graphs
• Phân tích mối quan hệ tỷ lệ thuận/nghịch giữa các yếu tố trong biểu đồ
• Tổng kết xu hướng chính trong overview

Ví dụ 1: Line Graph

Topic: The graph shows the relationship between average income and life expectancy in five countries from 1990 to 2020.

Sample sentence:
“The data reveals a clear correlation between economic prosperity and health outcomes. The higher the average income became in each country, the longer the life expectancy grew. For instance, in Japan, as GDP per capita rose from $25,000 to $40,000, life expectancy increased proportionally. Meanwhile, healthcare spending became more and more substantial over this period, rising from 8% to 12% of GDP.”

→ Vận dụng: Sử dụng “The higher…the longer” để thể hiện mối tương quan tỷ lệ thuận giữa thu nhập và tuổi thọ. “More and more substantial” mô tả xu hướng tăng liên tục của chi tiêu y tế.

Ví dụ 2: Bar Chart với xu hướng

Topic: The chart shows smartphone usage among different age groups from 2010 to 2023.

Sample sentence:
“Smartphone adoption increased across all demographics during this period. Among teenagers, usage became higher and higher, reaching 98% by 2023. An interesting pattern emerges: the younger the age group was, the faster the adoption rate increased. Conversely, the older the demographic, the more gradual the uptake of smartphone technology proved to be.”

→ Vận dụng: Kết hợp ba dạng Double Comparatives để mô tả xu hướng phức tạp, so sánh tốc độ thay đổi giữa các nhóm tuổi khác nhau. Thể hiện sự phân tích sâu, phù hợp Band 7.5+.

→ Vận dụng: Sử dụng Double Comparatives để mô tả sự gia tăng cường độ kiểm soát chất lượng theo các giai đoạn sản xuất.

Writing Task 2

Essay types sử dụng Double Comparatives:

1. Opinion Essay:

Topic: Some people believe that economic development is the most important goal for a country. Others argue that other types of progress are equally important. Discuss both views and give your opinion.

Body paragraph:

“Those who prioritize economic growth argue that the wealthier a nation becomes, the more resources it has to invest in other sectors such as education and healthcare. They contend that the stronger the economy is, the better the living standards citizens can enjoy. Historical evidence from developed nations supports this view – as GDP increased, poverty rates declined proportionally.

However, this perspective has limitations. The more countries focus exclusively on economic metrics, the more they neglect crucial aspects like environmental sustainability and social cohesion. We can observe that the faster some economies have grown, the more severe their pollution problems have become. China’s rapid industrialization serves as a prime example, where the higher the production output rose, the worse the air quality deteriorated in major cities.

In my view, a balanced approach is essential because the more holistically a country develops, the more sustainable its progress will be in the long term.”

→ Phân tích Band 8-9:

• Sử dụng Double Comparatives để xây dựng lập luận logic cho cả hai quan điểm
• Thể hiện mối quan hệ nhân quả rõ ràng
• Kết hợp với evidence và examples cụ thể
• Topic sentences mạnh với clear position
• Coherence cao với linking words

2. Problem-Solution Essay:

Topic: Traffic congestion is becoming a serious problem in many cities. What are the causes of this problem and what solutions can you suggest?

Sample paragraph:

“The root causes of traffic congestion are multifaceted and self-reinforcing. Firstly, the more a city’s population grows, the more vehicles appear on the roads. This creates a vicious cycle where the more congested the roads become, the longer commute times get, which frustrates drivers and reduces productivity. Furthermore, the less efficient public transportation is, the more people rely on private cars, exacerbating the problem.

To address these issues, governments must implement comprehensive solutions. Investment in public transportation is crucial because the better the public transport system is, the fewer people will choose to drive. Singapore demonstrates this principle effectively – the more they improved their MRT network, the less dependent residents became on cars. Additionally, the stricter parking regulations become, the more discouraged people are from driving into city centers.”

→ Phân tích:

• Double Comparatives thể hiện rõ mối quan hệ nhân quả trong problems
• Trong solutions, structure này giúp show expected outcomes
• Tự nhiên và persuasive, không mechanical
• Real-world example (Singapore) tăng tính thuyết phục

3. Advantage-Disadvantage Essay:

Topic: More and more people are working from home rather than at the workplace. Do the advantages outweigh the disadvantages?

Sample paragraph:

“Remote work offers several significant benefits. Employees enjoy greater flexibility, and the more control they have over their schedules, the better they can balance work and personal life. Additionally, companies are discovering that the more they allow flexible working arrangements, the higher employee satisfaction becomes. Research indicates that the fewer hours people spend commuting, the more productive they tend to be during actual working hours.

Nevertheless, working from home presents considerable challenges that are becoming more and more apparent over time. The more isolated employees feel, the less engaged they become with company culture. Many workers report that the longer they work remotely, the harder it is to maintain clear boundaries between professional and personal life. Team collaboration also suffers – the less face-to-face interaction teams have, the more difficult creative problem-solving becomes.”

→ Phân tích Band 8+:

• Balanced presentation của advantages và disadvantages
• Double Comparatives tạo sophisticated argument structure
• Cohesive devices tự nhiên
• Evidence-based với “research indicates”
• Complex sentence structures

4. Discussion Essay:

Topic: Some people think that environmental problems are too big for individuals to solve, while others believe individuals can make a difference. Discuss both views.

Sample paragraph:

“Advocates of individual action argue that collective small efforts create substantial impact. They point out that the more people adopt eco-friendly habits, the greater the cumulative effect on the environment. The more conscious consumers become about their choices, the more pressure corporations face to adopt sustainable practices. This market-driven change is already visible – the higher the demand for green products becomes, the more companies invest in environmentally friendly technologies.

Conversely, others maintain that systemic problems require systemic solutions. They argue that the larger the environmental challenge is, the more inadequate individual efforts appear. Climate change exemplifies this – the more complex the problem becomes, the more essential coordinated governmental action is. Furthermore, the less regulated industries are, the more environmental damage they cause, regardless of individual conservation efforts.”

→ Phân tích:

• Double Comparatives strengthen logical flow trong discussion
• Shows sophistication trong presenting contrasting views
• Natural integration with academic vocabulary
• Clear stance with nuanced understanding

Sample Paragraphs Band 7-9

Band 7 Sample:

Topic: The impact of social media on society

“Social media has transformed how people interact, but not always positively. The more time individuals spend on social platforms, the less time they dedicate to real-world relationships. Studies show that young people are becoming more and more isolated despite being digitally connected. The easier it becomes to communicate online, the harder many find face-to-face conversations. However, social media also offers benefits. The more diverse connections people make online, the broader their perspectives become. Businesses have discovered that the more actively they engage on social media, the stronger their customer relationships grow.”

Phân tích Band 7:

• Sử dụng Double Comparatives chính xác và đa dạng (4 lần)
• Variety: Cả “the…the…” và “comparative + and + comparative”
• Clear topic sentence và supporting ideas
• Evidence mention (“studies show”)
• Collocations: “real-world relationships”, “face-to-face conversations”, “customer relationships”
• Minor limitation: Có thể phát triển ideas sâu hơn

Band 8 Sample:

Topic: Urbanization and quality of life

“The phenomenon of rapid urbanization presents a complex paradox for modern societies. While cities offer unprecedented opportunities, the faster urban areas expand, the more strained their infrastructure becomes. Metropolitan regions in developing countries exemplify this trend particularly acutely – the more people migrate to urban centers, the more severe housing shortages grow. This creates a cascading effect where living costs spiral upward; the higher property prices become, the less affordable cities are for middle-income families. Consequently, income inequality intensifies as the wealthier neighborhoods become, the more impoverished surrounding areas tend to be. However, progressive urban planning can mitigate these challenges. Singapore’s experience demonstrates that the more thoughtfully cities are designed, the more sustainable their growth becomes. Their integrated approach shows that the better public services are coordinated, the higher residents’ quality of life rises, even amid density.”

Phân tích Band 8:

• Advanced usage: 6 instances với integration tự nhiên
• Complex ideas: Paradox, cascading effects, income inequality
• Sophisticated collocations: “unprecedented opportunities”, “metropolitan regions”, “acutely”, “progressive urban planning”, “integrated approach”
• Real-world example với detailed analysis (Singapore)
• Cohesive devices: “Consequently”, “However”, “Their…shows that”
• Sentence variety: Mix của simple, compound, và complex sentences
• Critical thinking: Shows cause-effect chains

Band 9 Sample:

Topic: Technology and human capability

“The relationship between technological advancement and human capability remains one of the most contentious debates in contemporary society. Proponents of automation argue persuasively that the more sophisticated machines become, the more liberated humans are to pursue creative and intellectual endeavors. This techno-optimistic perspective suggests that the better artificial intelligence handles routine tasks, the more opportunity humans have to develop uniquely human skills such as emotional intelligence and innovative thinking. Historical precedent appears to support this view – the more mechanized agricultural production became during the Industrial Revolution, the more society benefited from urbanization and specialized labor forces.

However, this narrative oversimplifies a nuanced reality. Empirical evidence increasingly reveals that the more automated certain industries become, the more precarious employment conditions grow for displaced workers. The paradox intensifies when we consider that the faster technology evolves, the harder it becomes for education systems to adequately prepare students for an unpredictable job market. Moreover, there exists an unsettling correlation whereby the more dependent societies become on technology, the more vulnerable they are to systemic failures and cyber threats. Recent global supply chain disruptions have starkly illustrated that the more interconnected and digitalized economic systems are, the more catastrophic singular points of failure can be. This suggests that the more enthusiastically we embrace technological solutions, the more critically we must assess their societal implications and develop robust contingency frameworks.”

Phân tích Band 9:

• Exceptional integration: 8 instances woven naturally into sophisticated argument
• Academic discourse: “contentious debates”, “techno-optimistic perspective”, “empirical evidence”, “nuanced reality”, “robust contingency frameworks”
• Complex argumentation: Thesis-antithesis structure với historical context
• Advanced vocabulary: “proponents”, “automation”, “liberated”, “precedent”, “oversimplifies”, “precarious”, “catastrophic”
• Cohesive mastery: “However, this narrative…”, “Moreover”, “This suggests that…”
• Critical depth: Paradox analysis, systemic thinking, real-world applications
• Sentence complexity: Extended complex sentences với multiple clauses
• Nuanced position: Balanced view với sophisticated understanding
• Error-free grammar và natural flow

So Sánh Với Cấu Trúc Tương Tự

Double Comparatives vs Simple Comparative

Tiêu chí	Double Comparatives	Simple Comparative
Công thức	The + comparative + S + V, the + comparative + S + V	S + V + comparative + than + object
Ý nghĩa	Mối quan hệ tương quan, hai thay đổi song song	So sánh đơn giản giữa hai đối tượng
Dùng khi	Thể hiện xu hướng, proportion, cause-effect	So sánh tính chất, đặc điểm cụ thể
Ví dụ	The more you practice, the better you become.	You are better than me at English.
IELTS context	Discussing trends, analyzing changes, showing correlation	Comparing two things directly
Band impact	7+ (sophisticated structure)	5-6 (basic structure)
Formality	Academic, formal	Both formal and informal

Khi nào dùng cấu trúc nào:

• Dùng Double Comparatives khi:

  • Mô tả xu hướng thay đổi theo thời gian
  • Giải thích mối quan hệ nhân quả
  • Phân tích tương quan tỷ lệ thuận/nghịch
  • Cần thể hiện grammatical range trong Writing Task 2
  • Ví dụ: “The more the city develops, the more job opportunities there are.”

• Dùng Simple Comparative khi:

  • So sánh trực tiếp hai đối tượng cụ thể
  • Đưa ra preference hoặc choice
  • Mô tả static comparison (không có thay đổi theo thời gian)
  • Ví dụ: “Online learning is more flexible than traditional classroom education.”

Double Comparatives vs Superlatives

Tiêu chí	Double Comparatives	Superlatives
Công thức	The + comparative…the + comparative / Comparative + and + comparative	The + superlative / Most/Least + adjective
Ý nghĩa	Mối quan hệ tương quan, progression	Mức độ cao nhất/thấp nhất trong nhóm
Dùng khi	Showing trends, correlation, gradual change	Highlighting the extreme in a group
Ví dụ	Life is becoming more and more expensive.	Tokyo is the most expensive city in the world.
Focus	Process, change over time	End result, ranking

Khi nào dùng cấu trúc nào:

• Dùng Double Comparatives: “As cities grow, they become more and more congested.” (process)
• Dùng Superlative: “Tokyo is the most congested city in Asia.” (ranking)

Có thể kết hợp: “Among all major cities, Tokyo has the most severe traffic problem, and it’s getting worse and worse each year.” (Superlative + Double Comparative for comprehensive description)

Lỗi Thường Gặp & Cách Sửa

Lỗi 1: Dùng Sai Cấu Trúc “The…The…”

❌ SAI:
“The more you study hard, the more your English will good.”

✅ ĐÚNG:
“The harder you study, the better your English will be.”

Giải thích:

• Lỗi 1: “study hard” → Phải dùng dạng so sánh của trạng từ “hard” → “harder”
• Lỗi 2: “will good” → “Good” là tính từ không thể đứng sau “will”, phải dùng “will be” + comparative “better”
• Quy tắc: Cả hai mệnh đề đều phải có cấu trúc: The + comparative + subject + verb

Lưu ý:

• “Hard” có hai vai trò: adjective (hard work) và adverb (work hard). Dạng comparative của cả hai là “harder”
• Sau modal verbs (will, can, should) + “be” + comparative adjective
• Đừng quên dấu phẩy ngăn cách hai mệnh đề

Thêm ví dụ đúng:

• “The more carefully you plan, the more successful you will be.”
• “The faster technology develops, the harder it is to keep up.”

Lỗi 2: Quên Thêm “And” Trong Cấu Trúc “Comparative + And + Comparative”

❌ SAI:
“The city is becoming more more crowded.”
“Traffic is getting worse, worse every day.”

✅ ĐÚNG:
“The city is becoming more and more crowded.”
“Traffic is getting worse and worse every day.”

Giải thích:
Học viên Việt Nam thường quên “and” vì trong tiếng Việt có thể nói “ngày càng đông đúc” mà không cần từ nối. Tuy nhiên, trong tiếng Anh, “and” là bắt buộc để nối hai comparative forms.

Quy tắc:

• Với tính từ/trạng từ ngắn: comparative + and + comparative (bigger and bigger)
• Với tính từ/trạng từ dài: more and more + adjective/adverb (more and more expensive)

Lưu ý:

• Không được viết: “more more expensive” ❌
• Không được viết: “more expensive and expensive” ❌
• Luôn nhất quán: “more and more expensive” ✅
• Cấu trúc tương tự với “less”: “less and less common”

Các ví dụ đúng:

• “People are becoming more and more dependent on technology.”
• “The problem is getting worse and worse.”
• “My English is improving better and better.” ❌ → “better and better” ✅

Lỗi 3: Dùng Sai Dạng So Sánh (Irregular Comparatives)

❌ SAI:
“The more good your vocabulary is, the more easy you can express ideas.”
“The more far you live, the more long your commute is.”

✅ ĐÚNG:
“The better your vocabulary is, the more easily you can express ideas.”
“The farther/further you live, the longer your commute is.”

Giải thích:
Một số tính từ và trạng từ có dạng so sánh bất quy tắc, không thêm “-er” hoặc “more”:

Irregular Comparatives:

• good/well → better (NOT more good)
• bad/badly → worse (NOT more bad)
• far → farther/further (NOT more far)
• little → less (NOT more little)
• much/many → more (NOT mucher)

Lưu ý đặc biệt:

• “Easy” là adjective, dạng comparative là “easier”, nhưng khi làm adverb phải dùng “easily” → “more easily”
• “Far”: farther (literal distance), further (figurative/abstract)
  • “The farther you drive, the more tired you get.” (physical distance)
  • “The further we discuss this issue, the more complex it becomes.” (abstract progression)

Các lỗi phổ biến khác:

• “more better” ❌ → “better” ✅ (double comparative error)
• “more worse” ❌ → “worse” ✅
• “more less” ❌ → “less” ✅

Lỗi 4: Dùng Nhầm “More” Với Tính Từ Ngắn

❌ SAI:
“The more fast you drive, the more dangerous it is.”
“Life is becoming more and more short.”
“The more tall buildings become, the more impressive they are.”

✅ ĐÚNG:
“The faster you drive, the more dangerous it is.”
“Life is becoming shorter and shorter.” (hoặc “increasingly brief”)
“The taller buildings become, the more impressive they are.”

Giải thích:
Học viên thường nhầm lẫn khi nào dùng “-er” và khi nào dùng “more”. Quy tắc:

Dùng “-er” với:

• Tính từ 1 âm tiết: fast → faster, tall → taller, short → shorter
• Tính từ 2 âm tiết kết thúc bằng -y, -er, -ow, -le:
  • happy → happier
  • clever → cleverer
  • narrow → narrower
  • simple → simpler

Dùng “more” với:

• Tính từ 2+ âm tiết: beautiful → more beautiful, expensive → more expensive
• Trạng từ kết thúc bằng -ly: quickly → more quickly, carefully → more carefully

Ngoại lệ cần nhớ:

• Một số tính từ 2 âm tiết có thể dùng cả hai: common → more common/commoner; quiet → more quiet/quieter
• Nhưng trong IELTS Writing, nên dùng “more common”, “more quiet” (formal hơn)

Lưu ý:

• “Quick” (adj) → quicker, nhưng “quickly” (adv) → more quickly
• “Early” (adj/adv) → earlier (không dùng “more early”)

Lỗi 5: Thiếu Subject Hoặc Verb Trong Mệnh Đề

❌ SAI:
“The more pollution, the more health problems.”
“The higher the price, more difficult to afford.”
“The technology advances faster, the more jobs.”

✅ ĐÚNG:
“The more pollution there is, the more health problems arise.”
“The higher the price is, the more difficult it is to afford.”
“The faster technology advances, the more jobs are created.”

Giải thích:
Đây là lỗi rất phổ biến với học viên Việt Nam vì trong tiếng Việt có thể lược bỏ chủ ngữ/động từ. Trong tiếng Anh, mỗi mệnh đề trong cấu trúc “The…the…” phải có đầy đủ subject và verb.

Cấu trúc đầy đủ:

The + comparative + SUBJECT + VERB, the + comparative + SUBJECT + VERB

Các trường hợp đặc biệt:

• Khi subject là “it” dummy subject:
  • “The higher the temperature is, the more uncomfortable it becomes.”
• Khi dùng “there is/are”:
  • “The more people there are, the more resources are needed.”
• Với passive voice:
  • “The more money is invested, the better the results are achieved.”

Lưu ý về word order:

• Khi subject là noun có mạo từ: “The higher the price is” (không đảo ngữ)
• Khi subject là pronoun: “The more I practice” (không đảo ngữ)
• Động từ “be” có thể lược bỏ trong một số trường hợp informal, nhưng trong IELTS nên giữ: “The sooner, the better” → “The sooner it is, the better it will be” (formal)

Top 5 mistakes Vietnamese learners make:

1. Missing “and” in “comparative + and + comparative”

   • Nguyên nhân: Vietnamese “ngày càng” không cần từ nối
   • Tần suất: 70% học viên mắc lỗi này
   • Cách tránh: Nhớ công thức bắt buộc có “and”

2. Using “more” with short adjectives

   • Nguyên nhân: Không phân biệt được tính từ ngắn/dài

   • Cách tránh: Học thuộc lòng quy tắc 1 âm tiết → “-er”

3. Incorrect irregular comparatives (more good, more bad)

   • Nguyên nhân: Áp dụng quy tắc thông thường cho tính từ bất quy tắc
   • Tần suất: 65% học viên mắc lỗi
   • Cách tránh: Học thuộc good→better, bad→worse, far→farther/further

4. Missing subject/verb in “the…the…” structure

   • Nguyên nhân: Ảnh hưởng từ tiếng Việt có thể lược bỏ chủ ngữ
   • Tần suất: 55% học viên mắc lỗi
   • Cách tránh: Luôn check cả hai mệnh đề có đầy đủ S + V

5. Wrong word order or form after “the”

   • Nguyên nhân: Không nắm vững cấu trúc “The + comparative + S + V”
   • Tần suất: 50% học viên mắc lỗi
   • Cách tránh: Practice với template và check grammar carefully

Đáp Án Bài Tập 5:

Sample paragraph – Topic 1: The impact of technology on education

“Technology has transformed education dramatically in recent years. The more advanced educational technology becomes, the more accessible learning opportunities are for students worldwide. Online platforms and digital resources are becoming more and more prevalent, enabling learners to study at their own pace. However, there is a concerning trend: the more students rely on technology, the less they develop critical thinking skills through traditional methods. Teachers must find a balance, ensuring that the more integrated technology is in classrooms, the more effectively it enhances rather than replaces fundamental learning processes. Overall, the better we harness technology’s potential, the more transformative education can become.”
