Cách Vận Dụng Vào IELTS

Speaking

Part 1 – Introduction & Interview:

Topic thường gặp: Hobbies, Work/Study, Hometown, Daily routines

Ví dụ câu hỏi & trả lời:

Q: “Why do you enjoy reading?”

A (Band 6): “I like reading because it’s relaxing and I can learn new things.”

A (Band 7-8): “The main reason I enjoy reading is that it allows me to escape from daily stress. Another important reason is that it broadens my knowledge about different cultures and perspectives, which I find incredibly valuable.”

→ Phân tích: Sử dụng “the main reason” và “another important reason” thể hiện khả năng organize ideas và tạo coherence. Tránh lặp “because” đơn giản.

Q: “What’s the reason for choosing your current job?”

A (Band 8): “The primary reason for choosing this career path was my genuine passion for technology. However, a significant reason was also the industry’s growth potential and the opportunity to work on innovative projects that could make a real impact.”

→ Phân tích: “Primary reason” và “significant reason” tạo hierarchy trong explanation, thể hiện sophisticated language use.

Part 2 – Long Turn:

Cue card example:

Describe a decision you made that you are proud of.

Sample answer (Band 8):

“I’d like to talk about my decision to study abroad, which I made two years ago.

The most significant reason for making this choice was my desire to experience international education and develop independence. Growing up in Vietnam, I had always been supported by my family, but I felt it was time to challenge myself in a completely new environment.

Another key reason why I decided to pursue overseas education was the academic reputation of universities in the UK. The specific program I chose offered cutting-edge research facilities and expert faculty members that simply weren’t available in my home country.

However, the underlying reason – the one that perhaps mattered most – was personal growth. I knew that living in a foreign country would push me out of my comfort zone and help me develop crucial life skills like problem-solving, cultural adaptation, and self-reliance.

Looking back, the reason this decision makes me proud is not just the academic achievements, but the person I’ve become through facing challenges independently. For this reason, I encourage other young people to consider similar opportunities for personal development.”

→ Phân tích Band 8+ features:

• Variety của structures: “most significant reason for”, “key reason why”, “underlying reason”
• Natural progression từ surface reasons đến deeper motivations
• Cohesive devices linking ideas
• Personal reflection với sophisticated vocabulary

Part 3 – Discussion:

Q: “Why do you think many young people are leaving rural areas?”

A (Band 6): “Because there are more jobs in cities and better facilities.”

A (Band 7-8): “I believe there are several factors at play. The primary reason for rural-urban migration is undoubtedly economic opportunity. Cities offer more diverse employment options and higher salaries. Another significant reason is access to better education and healthcare facilities, which are often limited in countryside areas. Additionally, an important reason why young people prefer urban life is the social and entertainment opportunities that simply don’t exist in rural communities.”

→ Phân tích: Multiple reasons với clear organization, academic tone phù hợp với Part 3 discussion level.

Q: “What’s the main reason for increasing obesity rates?”

A (Band 8-9): “One of the most significant reasons for the obesity epidemic is the dramatic shift in dietary patterns over recent decades. The proliferation of processed foods high in sugar and unhealthy fats has made poor nutrition incredibly convenient and affordable. However, the underlying reason is perhaps more complex – it involves socioeconomic factors where lower-income families often lack access to fresh, healthy food options. A further reason why obesity rates continue to rise is sedentary lifestyles; technological advancement has reduced physical activity in both work and leisure. For these reasons, addressing obesity requires multi-faceted policy interventions rather than individual responsibility alone.”

→ Phân tích Band 9 features:

• Sophisticated reasoning với “underlying reason” showing deeper analysis
• Complex sentence structures kết hợp reasons
• Academic vocabulary: proliferation, socioeconomic factors, multi-faceted interventions

Writing Task 1

Khi nào dùng:

• Giải thích sự khác biệt đáng kể giữa các categories trong biểu đồ
• Phân tích nguyên nhân của trends (nếu đề bài yêu cầu)
• Đưa ra possible explanation cho unusual patterns

In contrast, employment among older workers remained stable, the likely reason being their accumulated experience and specialized skills.”

→ Vận dụng: Dùng “possible reason” hoặc “likely reason” để đưa ra explanation không quá assertive, phù hợp với descriptive nature của Task 1.

Bar chart comparing:

“The chart reveals that expenditure on healthcare was substantially higher in Country A than Country B. One plausible reason for this disparity is the difference in population demographics, with Country A having a significantly older population requiring more medical services.”

Writing Task 2

Essay types sử dụng cấu trúc “reason”:

Opinion Essay

Topic: Some people believe that success comes from hard work, while others think luck plays a more important role. Discuss both views and give your opinion.

Body paragraph (Band 8):

“While luck certainly plays a role in success, I firmly believe that hard work is the more decisive factor. The fundamental reason for this perspective is that consistent effort creates opportunities rather than waiting for them to appear randomly. Take entrepreneurs, for example – a significant reason why successful business owners achieve their goals is their persistence through multiple failures. Steve Jobs faced bankruptcy before building Apple into a tech giant, demonstrating that the primary reason for long-term success is resilience and dedication, not fortunate circumstances. Furthermore, an important reason to emphasize hard work over luck is its controllability; individuals can actively improve their skills and knowledge, whereas luck remains entirely unpredictable. For these reasons, while acknowledging that timing matters, I maintain that hard work provides a far more reliable path to achievement than waiting for lucky breaks.”

→ Phân tích:

• Multiple “reason” structures tạo cohesion
• Clear topic sentence và concluding sentence
• Specific examples supporting reasons
• Logical flow of argument

Problem-Solution Essay

Topic: Many cities face serious traffic congestion. What are the reasons for this problem, and what solutions can you suggest?

Causes paragraph (Band 8):

“Urban traffic congestion stems from multiple interconnected factors. The most significant reason for gridlock in modern cities is rapid urbanization without corresponding infrastructure development. As populations concentrate in urban centers, existing road networks become overwhelmed. Another major reason why traffic has worsened is the cultural preference for private car ownership. In many developing nations, cars symbolize status and success, the reason being that public transportation is often perceived as inferior or unreliable. A further contributory reason is poor urban planning; many cities have developed residential areas far from employment centers, necessitating long commutes. Additionally, an underlying reason for persistent congestion is inadequate investment in alternative transport modes like cycling infrastructure or metro systems. These reasons collectively explain why traffic problems have become increasingly severe despite various attempted interventions.”

→ Phân tích:

• Progression từ most significant → further → underlying reasons
• Each reason explained with elaboration
• Causal relationships clearly established
• Academic vocabulary và complex structures

Solutions paragraph:

“Addressing these issues requires comprehensive strategies. The primary reason to invest in public transportation is that it can move far more people efficiently than private vehicles. Cities like Singapore have demonstrated this successfully. For this reason, governments should prioritize metro expansion and bus rapid transit systems. Another compelling reason to implement congestion pricing is that it creates financial incentives for behavioral change while generating revenue for transport improvements. The fundamental reason why integrated urban planning matters is that it reduces travel necessity by mixing residential, commercial, and recreational zones. For these reasons, a multi-pronged approach targeting infrastructure, pricing mechanisms, and urban design offers the best prospect for sustainable solutions.”

→ Phân tích:

• “Reason to” infinitive structure for solutions/recommendations
• Each solution linked to reasons from causes paragraph
• Evidence from real-world examples
• Clear concluding statement

Cause-Effect Essay

Topic: In many countries, the number of people suffering from stress-related illnesses is increasing. What are the causes of this problem, and what measures could be taken?

Body paragraph 1 – Causes (Band 8-9):

“The rise in stress-related health conditions can be attributed to several modern lifestyle factors. The principal reason for this alarming trend is the intensification of work culture in competitive economies. Employees face constant pressure to meet demanding targets, often working far beyond standard hours. A significant reason why this problem has escalated particularly in recent decades is technological connectivity; smartphones and laptops mean workers are never truly disconnected from job responsibilities. The underlying reason this causes health problems is chronic activation of the body’s stress response system, which was evolutionarily designed for short-term threats, not sustained pressure. Moreover, an important contributory reason is the erosion of work-life balance. Unlike previous generations who could separate professional and personal time, the reason modern workers struggle with stress is the blurring of these boundaries. Financial insecurity provides another fundamental reason – precarious employment and rising living costs create persistent anxiety about economic survival. These interconnected reasons create a perfect storm for stress-related illness proliferation.”

→ Phân tích Band 9 features:

• Sophisticated cause analysis với principal → significant → underlying reasons
• Scientific explanation (stress response system)
• Historical comparison adding depth
• Complex sentences linking multiple causes
• Academic register throughout

Discussion Essay

Topic: Some people think children should learn to compete, while others believe cooperation is more important. Discuss both views.

Paragraph supporting competition:

“Advocates of competitive education present several compelling arguments. The main reason for encouraging competition in schools is preparation for real-world career environments where individuals must distinguish themselves to advance. A significant reason why competition benefits students is that it drives excellence; when students strive to outperform peers, they often achieve higher standards than they would without such motivation. The underlying reason competition remains prevalent in education systems globally is its apparent effectiveness in identifying and nurturing talent.”

Paragraph supporting cooperation:

“However, proponents of cooperative learning offer equally persuasive reasoning. The primary reason for emphasizing collaboration is that most professional success requires teamwork rather than individual achievement. An important reason why cooperation may better serve students is that it develops crucial social skills including communication, empathy, and conflict resolution. A compelling reason to prioritize cooperative over competitive learning is mental health; excessive competition has been linked to anxiety, stress, and reduced self-esteem among young people. For this reason, many progressive educators advocate for collaborative pedagogical approaches.”

→ Phân tích:

• Balanced presentation của both viewpoints
• Parallel structure trong both paragraphs
• Each view supported với multiple reasons
• Maintains objectivity in discussion format

Sample Paragraphs Band 7-9

Band 7 Sample – Environmental Topic:

“Environmental degradation has accelerated dramatically in recent decades. The main reason for this deterioration is industrial pollution from factories and manufacturing plants that release harmful chemicals into air and water. Another significant reason is deforestation, which occurs because of agricultural expansion and logging activities. An important reason why this problem continues is that economic growth is often prioritized over environmental protection, particularly in developing nations. The reason governments struggle to address these issues effectively is the conflict between environmental regulations and business interests. These reasons demonstrate why environmental problems require both policy intervention and changes in corporate practices to achieve meaningful improvement.”

→ Phân tích Band 7:

• Clear structure với multiple reasons
• Accurate grammar và vocabulary
• Good variety của “reason” structures
• Logical organization
• Could improve: Deeper analysis, more sophisticated vocabulary, more complex sentences

Band 8-9 Sample – Education Topic:

“The quality of education systems varies enormously across nations, and the underlying reasons for these disparities are complex and multifaceted. The most fundamental reason certain countries achieve superior educational outcomes is substantial public investment in teacher training and competitive salaries that attract talented individuals to the profession. Finland exemplifies this approach, where teaching is among the most prestigious careers. A significant reason why some education systems fail is inadequate infrastructure and resources; the reason millions of children in developing regions receive substandard education is simply lack of access to basic facilities, textbooks, and qualified educators. However, the reason investment alone doesn’t guarantee success is that cultural attitudes toward learning play an equally crucial role. In societies where education is deeply valued, a compelling reason for high achievement is parental involvement and community support for academic excellence. The principal reason to examine these factors holistically rather than in isolation is that educational success emerges from the interaction of investment, culture, and policy. For these reasons, education reform requires comprehensive strategies addressing financial, social, and systemic dimensions simultaneously rather than simplistic solutions focusing on single variables.”

→ Phân tích Band 8-9:

• Sophisticated analysis với “underlying”, “fundamental” reasons showing depth
• Complex sentence structures integrating multiple ideas
• Specific examples (Finland) supporting claims
• Nuanced argument (investment alone insufficient)
• Academic vocabulary: multifaceted, infrastructure, holistically, comprehensive
• Cohesive devices linking ideas smoothly
• Critical thinking: moving beyond surface explanations
• Natural, fluent expression
• Varied sentence openings và structures

“The reason of traffic congestion is too many cars.”

✅ ĐÚNG:
“The reason for traffic congestion is too many cars.”

Giải thích:
Trong tiếng Anh, không tồn tại cấu trúc “reason of”. Giới từ đúng sau “reason” là FOR (khi theo sau noun/gerund) hoặc WHY (khi theo sau clause). Đây là lỗi phổ biến của học viên Việt Nam vì trong tiếng Việt ta nói “lý do của việc gì đó”.

Lưu ý:

• Reason FOR + noun/gerund ✓
• Reason WHY + clause ✓
• Reason OF ✗ (không tồn tại)
• Reason TO + infinitive ✓ (với nghĩa khác – mục đích)

Thêm ví dụ sai thường gặp:

• ❌ “The reason of his absence was illness.”
• ✅ “The reason for his absence was illness.”

Lỗi 2: Thiếu “is/was” trong cấu trúc

❌ SAI:
“The main reason for pollution the excessive use of fossil fuels.”

✅ ĐÚNG:
“The main reason for pollution is the excessive use of fossil fuels.”

Giải thích:
Cấu trúc “reason for” cần linking verb (is/was/will be) để kết nối với explanation. Nhiều học viên Việt Nam bỏ qua verb vì trong tiếng Việt có thể nói “Lý do của ô nhiễm là việc sử dụng nhiên liệu hóa thạch” mà không cần động từ rõ ràng.

Công thức đúng:

[Subject with "reason"] + IS/WAS + [explanation]

Lưu ý:

• Nếu subject là singular (a reason, the reason): dùng is/was
• Nếu subject là plural (reasons, several reasons): dùng are/were

Thêm ví dụ:

• ❌ “The reasons for success hard work and determination.”
• ✅ “The reasons for success are hard work and determination.”

Lỗi 3: Dùng sai thì của verb sau “reason why”

❌ SAI:
“The reason why I choose this topic was its relevance.”

✅ ĐÚNG:
“The reason why I chose this topic was its relevance.”
hoặc
“The reason why I choose this topic is its relevance.”

Giải thích:
Thì của động từ trong clause sau “reason why” phải tương ứng với thì của main verb (is/was). Nếu dùng “was” (past), thì verb trong “why clause” cũng phải là past. Học viên Việt Nam thường inconsistent về tense vì trong tiếng Việt không có biến đổi thì rõ ràng.

Quy tắc tense agreement:

• Present: “The reason why I choose… is…”
• Past: “The reason why I chose… was…”
• Present Perfect: “The reason why I have chosen… is…”

Thêm ví dụ sai:

• ❌ “The reason why many students failed the exam is they don’t study enough.” (mixing present and past reference)
• ✅ “The reason why many students failed the exam was that they didn’t study enough.”
• ✅ “The reason why many students fail exams is that they don’t study enough.” (general truth – present)

Lỗi 4: Quên “that” sau linking verb

❌ SAI:
“The reason for the delay the train broke down.”

✅ ĐÚNG:
“The reason for the delay is that the train broke down.”

Giải thích:
Khi explanation sau linking verb là một complete clause (có subject + verb), bạn PHẢI dùng “is that” hoặc “was that” để giới thiệu clause đó. Không thể nối trực tiếp reason phrase với explanation clause.

Công thức đúng:

The reason for [noun] + is/was + THAT + [complete clause]

So sánh:

• ✅ “The reason for the delay is bad weather.” (noun phrase – không cần “that”)
• ✅ “The reason for the delay is that the weather was bad.” (complete clause – cần “that”)

Thêm ví dụ:

• ❌ “An important reason for climate change humans burn fossil fuels.”
• ✅ “An important reason for climate change is that humans burn fossil fuels.”

Lưu ý: Với “reason why”, có thể bỏ “that” trong informal contexts:

• Formal: “The reason why I left was that I felt unwell.”
• Less formal: “The reason why I left was I felt unwell.” (acceptable in Speaking)

Lỗi 5: Dùng “reason” với động từ không phù hợp

❌ SAI:
“The reason happens because of economic factors.”
“Several reasons occur for this problem.”

✅ ĐÚNG:
“This happens because of economic reasons.”
“Several reasons exist for this problem.”
hoặc
“Several reasons can be identified for this problem.”

Giải thích:
“Reason” là abstract noun, không phải agent thực hiện hành động. Không dùng action verbs như “happen”, “occur” với “reason” làm subject. Học viên Việt Nam hay mắc lỗi này do influenced bởi “lý do xảy ra” trong tiếng Việt.

Verbs phù hợp với “reason” làm subject:

• ✅ Reasons exist
• ✅ Reasons can be found
• ✅ Reasons have been identified
• ✅ Reasons include
• ✅ Reasons are (linking verb)
• ✅ Reasons may explain

Verbs KHÔNG dùng:

• ❌ Reasons happen
• ❌ Reasons occur
• ❌ Reasons make
• ❌ Reasons cause (reason không “cause” – reason giải thích cause)

Cấu trúc đúng:

• ❌ “The reason causes pollution…”
• ✅ “Pollution occurs for several reasons…”
• ✅ “The reason for pollution is…”

Lỗi 6: Lặp lại “reason” và “because” trong cùng một câu

❌ SAI:
“The reason for traffic congestion is because there are too many cars.”

✅ ĐÚNG:
“The reason for traffic congestion is that there are too many cars.”
hoặc
“Traffic congestion occurs because there are too many cars.”

Giải thích:
Đây là lỗi redundancy (thừa từ) rất phổ biến. “Reason” và “because” đều diễn đạt causation, nên không dùng cả hai cùng lúc. Sau “the reason is”, dùng “that” chứ không phải “because“.

Pattern sai thường gặp:
❌ “The reason why… is because…”
❌ “The reason for… is because…”

Corrections:
✅ “The reason why… is that…”
✅ “The reason for… is that…”
✅ hoặc loại bỏ “reason” structure hoàn toàn và chỉ dùng “because”

So sánh:
| Sai | Đúng |
|—–|——|
| The reason I left is because I was tired. | The reason I left is that I was tired. / I left because I was tired. |
| The reason for his success is because he works hard. | The reason for his success is that he works hard. / He succeeds because he works hard. |

Lỗi 7: Dùng sai mạo từ với “reason”

❌ SAI:
“Reason for this problem is lack of funding.”
“The one of reasons is economic pressure.”

✅ ĐÚNG:
“A/The reason for this problem is lack of funding.”
“One of the reasons is economic pressure.”

Giải thích:
“Reason” là countable noun, cần mạo từ (a/an/the) hoặc determiner. Học viên Việt Nam hay bỏ mạo từ vì tiếng Việt không có articles.

Quy tắc mạo từ:

• A reason – một lý do trong nhiều lý do (indefinite)
• The reason – lý do cụ thể, xác định (definite)
• One reason – một trong số các lý do
• The main/primary reason – lý do chính
• Reasons (plural) – không cần mạo từ cho general statement

Pattern “one of”:

• ❌ “One of reason is…”
• ✅ “One of the reasons is…”
• ✅ “One reason is…” (không có “of”)

“Learning a second language is increasingly important in today’s globalized world.

Another important reason why people learn foreign languages is to experience different cultures more authentically when traveling. A further reason is cognitive benefits; research shows bilingual individuals develop better problem-solving and multitasking abilities. Perhaps the fundamental reason to invest time in language learning is the personal growth it brings, expanding one’s worldview and fostering cross-cultural understanding. For these reasons, language education should be prioritized in school curricula to prepare students for an interconnected future.”

Kết Bài

Việc thành thạo cấu trúc “A Significant Reason For” và “Important Reason” là yếu tố then chốt để nâng band điểm IELTS của bạn từ 6.5 lên 7.5 hoặc cao hơn. Các examiner đặc biệt chú ý đến khả năng giải thích nguyên nhân một cách logic, organized và sophisticated – đây chính là điểm mạnh của các cấu trúc này.

Điểm nhấn quan trọng cần nhớ:

Variety là chìa khóa: Đừng chỉ lặp lại “the reason is” suốt bài. Thay đổi giữa “significant reason for”, “important reason why”, “primary reason to”, “one of the key reasons” để thể hiện grammatical range.

Formal vs Conversational: Trong Writing Task 2, ưu tiên “reason for” structures với academic vocabulary. Trong Speaking, bạn có thể linh hoạt hơn nhưng vẫn nên demonstrate variety.

Avoid redundancy: Không bao giờ dùng “the reason is because” – đây là lỗi nghiêm trọng giảm điểm. Luôn nhớ: “the reason is that” hoặc chỉ dùng “because” mà không cần “reason”.

Context matters: “Reason for” + noun/gerund; “Reason why” + complete clause. Hiểu rõ sự khác biệt này giúp bạn tránh lỗi ngữ pháp cơ bản.

Band 8+ features: Kết hợp “reason” structures với relative clauses, participles, và conditional sentences. Sử dụng academic collocations như “underlying reason”, “fundamental reason”, “compelling reason”.
