Tại sao quan trọng

Trong Part 2 (cue card) và Part 3 (discussion), examiner thường hỏi bạn so sánh: - "Compare your country now with 20 years ago." - "Is it better to work from home or in an office?" - "How are young people today different from previous generations?"

Câu trả lời có cấu trúc so sánh rõ ràng nghe thông minh, có chiều sâu và đạt điểm cao về Coherence & Cohesion. Câu trả lời chỉ liệt kê hai điểm rời rạc nghe yếu và thiếu tổ chức.

Mẫu câu trả lời hoàn chỉnh (Part 3)

Q: Do you think people's lifestyles have changed compared to 50 years ago?

"Yes, dramatically. In the past, most people led much simpler lives — they lived near where they were born, worked in physical jobs, and socialised primarily with neighbours and family. Whereas previous generations rarely travelled far, people today are far more mobile and connected globally. However, I think this comes at a cost — while modern life is more convenient and stimulating, it's also more stressful and isolating in some ways. On the other hand, access to healthcare, education, and technology has improved enormously, so overall, I'd say the changes have been positive, although not without trade-offs."

Q: Is it better to live in the city or the countryside?

"I think it really depends on what you value. City life offers far more career opportunities, better infrastructure, and a wider social life — whereas rural areas tend to be quieter, more affordable, and closer to nature. For ambitious, career-focused people, cities are probably better. On the other hand, for families with children or people who prioritise wellbeing over career advancement, the countryside often suits them better. Personally, I prefer the city, mainly because I'm quite career-focused at this stage of my life, although I could see myself moving somewhere quieter eventually."

Tóm tắt nhanh

Tính từ ngắn (1-2 âm tiết): -er / the -est - Thêm -er/-est: tall → taller → the tallest - Nhân đôi phụ âm: big → bigger → the biggest - -y → -ier/-iest: happy → happier → the happiest

Tính từ dài (3+ âm tiết): more / the most - more beautiful / the most beautiful

Không dùng "very" trước comparative — dùng "much/far/a lot/even" thay thế!

Lỗi phổ biến — "more better" và bỏ "than"

Lỗi 1: Stack "more" + comparative form

Tiếng Việt "hơn" có thể đi với mọi tính từ. Người học VN bê "more" + đã-comparative-rồi → double comparative.

❌ "She is more better than him." → ✅ "She is better than him." ❌ "Hanoi is more bigger than Da Nang." → ✅ "Hanoi is bigger than Da Nang." ❌ "This problem is more more difficult." → ✅ "This problem is more difficult."

Quy tắc: Adjective ngắn (1 syllable, hoặc 2 syllables ending in -y) → -er. Adjective dài → more + adj. KHÔNG đi cùng nhau.

Lỗi 2: Bỏ "than"

Tiếng Việt có thể so sánh bằng juxtaposition: "tôi cao bạn" (= cao hơn). English bắt buộc "than".

❌ "She is taller me." → ✅ "She is taller than me." ❌ "Hanoi is older Saigon." → ✅ "Hanoi is older than Saigon."

Mẹo: Mọi comparative cần có ít nhất một trong: "than X" (so với X) hoặc context rõ ràng (e.g., "Which is bigger?" — câu trả lời ellipsis chấp nhận).
