Cách Vận Dụng Vào IELTS

Speaking

Part 1 – Introduction & Interview

Part 1 ít khi yêu cầu sử dụng các trạng từ này vì câu hỏi thường về preferences và routines. Tuy nhiên, bạn có thể sử dụng nếu câu hỏi liên quan đến past mistakes.

Topic: Learning experiences

Q: “Have you ever made a mistake when learning something new?”

A: “Yes, definitely. When I first started learning to play guitar, I foolishly thought I could skip the basics and jump straight to playing complex songs. That approach really slowed down my progress and I had to go back and learn the fundamentals properly.”

→ Phân tích: Sử dụng “foolishly” để mô tả sai lầm cá nhân, thể hiện self-awareness và tạo câu chuyện sinh động.

Part 2 – Long Turn

Cue Card Example:

Describe a time when you made a wrong decision

You should say:

• What the decision was
• When you made it
• Why it was wrong
• And explain what you learned from it

Sample Answer (Band 8.0):

“I’d like to talk about a poor financial decision I made during my first year at university. I foolishly decided to purchase an expensive laptop that was far beyond my budget, simply because my friends had similar models. I unwisely borrowed money from multiple sources without considering how I would repay it.

Looking back, I realize I foolishly assumed that I could easily find a part-time job to cover the costs. However, balancing studies and work proved more challenging than expected. I unwisely prioritized status over practicality, which caused significant financial stress.

The situation taught me valuable lessons about financial planning and not making impulsive purchases. I learned that it’s important to wisely consider all consequences before making major financial commitments. This experience shaped my approach to money management and helped me develop more responsible spending habits.”

→ Band 8+ Features:

• Multiple uses of target adverbs in natural contexts
• Past tense consistency
• Clear narrative structure
• Reflection and lesson learned
• Vocabulary range (impulsive, consequences, commitments)

Part 3 – Discussion

Topic: Decision-making and financial management

Q: “Why do you think people often make poor financial decisions?”

A: “There are several reasons for this phenomenon. Firstly, many young people foolishly believe that they’ll always have enough income to cover their expenses, which leads to overspending. Secondly, advertising and social media pressure cause individuals to unwisely prioritize material possessions over savings.

Moreover, financial education is often lacking in schools, so people unwisely make major financial decisions without proper knowledge. They might foolishly ignore the long-term consequences of debt, focusing only on immediate gratification. I think if people were better educated about personal finance, they would more wisely choose how to allocate their resources.”

→ Band 9 Features:

• Complex sentence structures
• Clear topic sentences with supporting details
• Sophisticated vocabulary (phenomenon, gratification, allocate)
• Natural use of discourse markers (Firstly, Moreover)
• Balanced argument with solution

Writing Task 2

Essay Type: Opinion Essay

Topic: “Some people believe that young adults should be allowed to make their own financial decisions without parental interference. To what extent do you agree or disagree?”

Body Paragraph 1 (Band 8.0):

“While independence is important for personal development, completely unrestricted financial freedom can lead to serious consequences. Young adults often lack the experience needed to make sound financial choices and may unwisely invest their money in risky ventures or foolishly spend beyond their means. For instance, research from the UK’s Financial Conduct Authority shows that individuals under 25 are three times more likely to fall victim to financial scams because they foolishly trust online investment schemes without proper verification. Furthermore, without parental guidance, young people might unwisely accumulate significant credit card debt, which can damage their credit scores and limit future opportunities such as securing mortgages or business loans. Therefore, some level of parental oversight serves as a protective measure against poor financial decisions.”

→ Phân tích:

• Foolishly/Unwisely được sử dụng 4 lần một cách tự nhiên
• Kết hợp với evidence (research, statistics)
• Complex sentences với relative clauses
• Academic tone maintained throughout
• Clear topic sentence và concluding sentence

Body Paragraph 2 (Band 8.5):

“However, it would be equally unwise to prevent young adults from making any independent financial decisions. Financial literacy is best developed through practical experience, and those who wisely learn from small mistakes in their twenties are better equipped for larger financial responsibilities later. Countries like Singapore have recognized this by implementing structured financial education programs that teach young people to wisely budget and avoid foolishly committing to obligations they cannot fulfill. Moreover, excessive parental control can create dependency and prevent the development of essential life skills. Young adults need opportunities to wisely assess risks and rewards, even if they occasionally unwisely choose less optimal options. The key lies in finding a balance between guidance and autonomy.”

→ Band 8.5+ Features:

• Balanced argument with concession
• Real-world example (Singapore)
• Varied sentence structures
• Natural integration of adverbs with different forms (wisely learn, avoid foolishly)
• Sophisticated linking

Writing Task 1

Context: Academic Report describing investment trends

Sample Sentence:

“The data reveals that many investors unwisely concentrated their portfolios in a single sector during the period between 2015 and 2018, which contributed to significant losses when the market corrected in 2019.”

→ Usage note: Task 1 ít yêu cầu judgmental language, nhưng có thể dùng trong overview hoặc khi describe obvious negative trends.

Academic Report Example:

“The graph illustrates changes in household savings rates across five countries from 2010 to 2020. Notably, Country A’s savings rate declined dramatically from 15% to 5%, suggesting that households may have unwisely reduced their emergency funds during this period of economic uncertainty.”

→ Band 7+ tip: Chỉ sử dụng “unwisely” khi data rõ ràng cho thấy negative consequence, không abuse judgmental adverbs.

Lỗi Thường Gặp & Cách Sửa

Lỗi 1: Đặt Sai Vị Trí Trạng Từ

❌ SAI:

“He invested foolishly all his money in cryptocurrency.”

✅ ĐÚNG:

“He foolishly invested all his money in cryptocurrency.”

HOẶC

“He invested all his money foolishly in cryptocurrency.”

Giải thích:

Trạng từ chỉ cách thức thường đứng TRƯỚC động từ chính (foolishly invested) hoặc CUỐI cụm động từ (invested… foolishly). Không đặt giữa động từ và tân ngữ trực tiếp của nó.

Lưu ý:

• Vị trí phổ biến nhất: Subject + adverb + verb
• Vị trí nhấn mạnh: Adverb, subject + verb (có dấu phấy)
• Với auxiliary verbs: Subject + aux + adverb + main verb

Thêm ví dụ:

❌ “She spent unwisely her entire salary.”

✓ “She unwisely spent her entire salary.”

✓ “She spent her entire salary unwisely.”

Lỗi 2: Nhầm Lẫn Tính Từ và Trạng Từ

❌ SAI:

“It was a foolishly decision to quit his job.”

✅ ĐÚNG:

“It was a foolish decision to quit his job.”

HOẶC

“He foolishly decided to quit his job.”

Giải thích:

• Foolish = adjective (tính từ) → bổ nghĩa cho danh từ (foolish decision)
• Foolishly = adverb (trạng từ) → bổ nghĩa cho động từ (foolishly decided)

Không dùng adverb để bổ nghĩa cho noun!

Lưu ý:

Cấu trúc đúng:

• Adjective + Noun: “an unwise choice”, “a foolish mistake”
• Adverb + Verb: “unwisely choose”, “foolishly believe”

Thêm ví dụ:

❌ “That was an unwisely investment.”

✓ “That was an unwise investment.”

✓ “They unwisely invested in that company.”

Lỗi 3: Dùng Không Phù Hợp Với Ngữ Cảnh Formal/Informal

❌ SAI (quá informal cho Writing Task 2):

“The government foolishly messed up the economy.”

✅ ĐÚNG:

“The government unwisely mismanaged economic policies.”

Giải thích:

• Foolishly + informal verb (messed up) = not appropriate cho Academic Writing
• Unwisely + formal verb (mismanaged) = suitable cho IELTS Writing Task 2

Lưu ý:

Trong Writing Task 2:

• Prefer: unwisely (more formal)
• Combine with: academic verbs (allocate, implement, prioritize, disregard)

Trong Speaking Part 3:

• Both foolishly và unwisely acceptable
• Foolishly: more conversational, natural
• Unwisely: shows vocabulary range

Thêm ví dụ:

Speaking Part 2 (OK):
✓ “I foolishly thought I could learn everything the night before the exam.”

Writing Task 2 (Better):
✓ “Students unwisely believe that cramming is an effective study strategy.”

Lỗi 4: Dùng Với Động Từ Không Phù Hợp

❌ SAI:

“The weather foolishly changed yesterday.”

✅ ĐÚNG:

“He foolishly went out without an umbrella when the weather forecast predicted rain.”

Giải thích:

Foolishly/unwisely chỉ dùng với actions có conscious decision (hành động có ý thức quyết định). Không dùng với:

• Natural phenomena (thời tiết, thiên nhiên)
• Involuntary actions (vô ý thức)
• States of being (trạng thái)

Lưu ý:

Dùng ĐƯỢC với:

• Decision-making verbs: decide, choose, believe, assume, trust
• Action verbs: spend, invest, ignore, reject, pursue
• Behavior verbs: behave, act, respond

KHÔNG dùng với:

• Natural processes: occur, happen (weather changed)
• States: be, seem, appear
• Emotions: feel, love (trừ khi là conscious choice)

Thêm ví dụ:

❌ “The stock market foolishly crashed.”

✓ “Investors foolishly panicked and sold all their stocks when the market dipped slightly.”

❌ “The building unwisely collapsed.”

✓ “Engineers unwisely overlooked structural weaknesses, which led to the building’s collapse.”

Lỗi 5: Lạm Dụng Trong Một Bài Viết

❌ SAI (overuse):

“Many people foolishly spend too much. They foolishly believe money is unlimited. Young adults foolishly use credit cards. Parents foolishly don’t teach children about money. Society foolishly promotes consumerism.”

✅ ĐÚNG:

“Many people unwisely spend beyond their means because they mistakenly believe their income will always increase. Young adults often make poor financial decisions with credit cards, partly because parents fail to provide adequate financial education. Additionally, society unfortunately promotes excessive consumerism through advertising.”

Giải thích:

Sử dụng cùng một adverb nhiều lần trong một paragraph làm:

• Giảm vocabulary range (Band score dropped)
• Sound repetitive và unnatural
• Mất điểm Lexical Resource

Lưu ý:

Synonyms và alternatives:

• Foolishly/Unwisely → mistakenly, incorrectly, unfortunately, regrettably
• Foolish decision → poor judgment, unwise choice, misguided action
• Use paraphrase: “make the mistake of”, “fail to consider”, “overlook the importance”

Best practice:

Trong một essay (250-280 words):

• Maximum 2-3 lần foolishly/unwisely
• Combine với synonyms
• Vary sentence structures

Đáp Án Bài Tập 5 (Sample Band 8.0 Paragraph):

Topic: “Many young people today prefer to spend money on experiences rather than saving for the future. Discuss the advantages and disadvantages of this trend.”

Sample Answer:

“While prioritizing experiences over savings can enrich young people’s lives, this trend also carries significant financial risks. On the positive side, investing in travel, education, and social activities provides valuable personal development and creates lasting memories that contribute to overall wellbeing. However, many young adults unwisely neglect long-term financial planning, assuming they will have opportunities to save later in life. They foolishly believe that experiences are more important than financial security, without considering potential emergencies or retirement needs. For instance, recent surveys show that individuals who spent lavishly in their twenties often unwisely accumulated substantial debt and struggled to purchase homes in their thirties. Therefore, while experiences are valuable, completely disregarding savings represents an unwise approach to financial management. A balanced strategy that allocates funds for both current enjoyment and future security would be more prudent than foolishly spending everything on immediate gratification.”

Đáp Án Bài Tập 6 (Sample Speaking Answers):

Question 1: Describe a time when you made a wrong decision.

Sample Answer (Band 8.0):

“I’d like to talk about a time during my first year at university when I foolishly decided to take six courses simultaneously, thinking I could handle the workload. I unwisely believed that I was more capable than I actually was, and I foolishly ignored advice from senior students who warned me about burnout.

The consequences were quite severe. My grades suffered significantly, and I experienced considerable stress. I had foolishly assumed that I could maintain high performance in all subjects while also participating in extracurricular activities, but this proved impossible. Looking back, I realize I should have been more realistic about my limitations and started with a normal course load.

This experience taught me valuable lessons about self-awareness and the importance of wisely managing my commitments. Now I always carefully consider my capacity before making such decisions, and I’ve learned that quality is more important than quantity when it comes to academic pursuits.”

Question 2: Why do you think people sometimes make poor financial decisions?

Sample Answer (Band 8.5):

“There are several interconnected reasons why people make poor financial decisions. Firstly, many individuals, especially young adults, foolishly trust their financial intuition without seeking professional advice or conducting proper research. They unwisely assume that managing money is straightforward, when in reality it requires considerable knowledge and discipline.

Secondly, emotional factors play a significant role. People often foolishly make impulsive purchases driven by social pressure or advertising rather than genuine need. They unwisely prioritize immediate satisfaction over long-term benefits, which leads to overspending and debt accumulation.

Moreover, inadequate financial education in schools means many people unwisely enter adulthood without understanding basic concepts like compound interest, investment risks, or budget planning. They’ve never learned to wisely evaluate financial opportunities and risks, so they’re vulnerable to scams or poor investment choices.

Finally, some people foolishly believe they’ll always have enough income to cover their expenses, without preparing for emergencies or economic downturns. This optimism bias causes them to unwisely neglect building emergency funds or insurance coverage.”
