During, While, For Là Gì?
Định Nghĩa Cơ Bản
DURING là giới từ (preposition) được sử dụng để chỉ khoảng thời gian mà một sự việc diễn ra. During luôn đi kèm với danh từ hoặc cụm danh từ, không bao giờ đi với mệnh đề có động từ.
Chức năng chính:
- Chỉ thời điểm xảy ra sự việc trong một khoảng thời gian cụ thể
- Nhấn mạnh “trong suốt” hoặc “vào lúc nào đó trong” khoảng thời gian đó
- Tạo mối liên hệ giữa hành động và giai đoạn thời gian
WHILE là liên từ (conjunction) dùng để nối hai mệnh đề, chỉ hai hành động xảy ra đồng thời hoặc tương phản. While luôn được theo sau bởi một mệnh đề hoàn chỉnh có chủ ngữ và động từ.
Chức năng chính:
- Chỉ hai hành động diễn ra cùng lúc
- Thể hiện sự tương phản giữa hai ý tưởng
- Nối hai mệnh đề có quan hệ thời gian với nhau
FOR là giới từ chỉ khoảng thời gian kéo dài của một hành động hoặc trạng thái. For luôn đi kèm với một con số hoặc cụm từ chỉ độ dài thời gian.
Chức năng chính:
- Chỉ độ dài/thời lượng của một hành động
- Trả lời câu hỏi “How long?” (Bao lâu?)

Sample Band 8 Answer:
“I’d like to talk about when I learned photography during the pandemic in 2020. For about six months, I dedicated myself completely to this hobby.
During the lockdown period, I had a lot of free time and decided to learn something creative. While many people were watching Netflix, I chose to invest my time in developing a practical skill. I watched online tutorials for hours every day and practiced constantly.
While I was learning the technical aspects like aperture and shutter speed, I also developed an artistic eye. During my daily walks – which were permitted for one hour each day – I would take my camera and photograph everything interesting I encountered.
For the first few weeks, my photos were terrible. However, during the third month, I started seeing real improvement. While practicing, I joined an online community where photographers shared their work. For several months, I posted photos daily and received valuable feedback.
By the end of the six-month period, I had taken over 5,000 photos and felt confident in my abilities. During that challenging time, photography became my escape and passion. Now, even though the pandemic has ended, I still practice photography for at least a few hours every weekend.”

Q: How has technology changed education in your country?
✅ Band 8-9 Answer:
“Well, technology has transformed education dramatically, especially during the past decade. While traditional teaching methods still dominate in many schools, digital tools are becoming increasingly prevalent.
For instance, during my parents’ generation, students relied entirely on textbooks and teachers. However, while today’s students still use traditional resources, they also have access to online platforms, video tutorials, and interactive applications.
During the pandemic, we saw an acceleration of this trend. For nearly two years, schools operated online, which while challenging initially, demonstrated the potential of digital education. While some students thrived in this environment, others struggled without face-to-face interaction.
Looking ahead, I believe that for the foreseeable future, we’ll see a hybrid model. While technology will continue to advance, the human element in education will remain crucial. During my own education, I’ve experienced both methods, and I can say that each has distinct advantages.”

Writing Task 1 – Line Graph
Sample Question: The graph shows the number of international students in Australia from 2000 to 2020.
Sample Band 8 Answer:
“The line graph illustrates the changes in the international student population in Australia over a twenty-year period from 2000 to 2020.
Overall, the number of international students increased significantly during this period, while there were some fluctuations in certain years. The figure rose steadily for the first decade before experiencing more volatile changes.
In 2000, approximately 200,000 international students were enrolled. During the first five years, the number grew gradually, reaching 300,000 by 2005. For the next five years, growth accelerated, with the figure climbing to 500,000 by 2010.
While the trend remained generally upward, during the period between 2010 and 2015, the rate of increase slowed. The figure plateaued for approximately two years before resuming growth. During 2018 and 2019, numbers peaked at around 700,000.
However, while enrollment had been rising steadily, 2020 saw a sharp decline due to the pandemic. During this year, the number dropped by 150,000, falling to 550,000. For the first time in two decades, the trend reversed dramatically.”

Writing Task 1 – Process Diagram
Sample Question: The diagram shows how coffee is produced from coffee beans.
Sample Band 7 Answer:
“The diagram illustrates the coffee production process from harvesting beans to the final packaged product.
During the initial stage, coffee cherries are hand-picked from coffee plants. While this harvesting occurs, workers select only ripe red cherries. These cherries are then dried for several weeks, either in the sun or using mechanical dryers.
While the cherries are drying, they are turned regularly to ensure even moisture removal. During this drying period, the moisture content reduces from approximately 60% to 12%. The process typically continues for 2-4 weeks depending on weather conditions.
Once dried, the outer layers are removed during the hulling stage. While this happens, the green coffee beans are separated and graded by size and quality. For the next stage, beans are roasted at high temperatures for 10-15 minutes. During roasting, the beans change color from green to brown.
Finally, while the beans are still fresh, they are packaged and sealed. The entire process, from harvest to packaging, takes approximately for one to two months. During this time, quality control checks occur at multiple stages to ensure consistency.”

Writing Task 2 – Opinion Essay
Question: Some people believe that children should be allowed to use smartphones during school hours. To what extent do you agree or disagree?
Sample Band 8-9 Answer:
“The question of whether smartphones should be permitted during school hours has become increasingly contentious. While technology advocates argue that these devices facilitate learning, I largely disagree with allowing unrestricted smartphone use in educational settings.
Admittedly, smartphones can serve educational purposes during lessons. While students are working on projects, they can quickly access information, use educational applications, and collaborate with peers. For example, during science classes, students can use smartphone cameras to document experiments or access scientific databases. For subjects like language learning, applications provide interactive practice that traditional textbooks cannot match.
However, the disadvantages of smartphone use during school hours outweigh these benefits. While devices may occasionally support learning, research shows that students check their phones for non-educational purposes more than 100 times daily. During lectures, notifications constantly interrupt concentration, fragmenting students’ attention spans. Studies indicate that students who use smartphones during class perform significantly worse on assessments. For instance, a 2019 study found that students who avoided phones during lessons scored 15% higher than those with unrestricted access.
Moreover, while children are developing crucial social skills, smartphone use interferes with face-to-face interactions. During break times, students increasingly focus on screens rather than engaging with classmates. For years, educators have observed declining social competence among children who spend excessive time on devices. While digital communication has value, it cannot replace the interpersonal skills developed through direct interaction.
In conclusion, while smartphones offer some educational benefits, I believe they should be restricted during school hours. For the sake of academic performance and social development, schools should implement clear policies limiting smartphone access to specific, supervised educational contexts.”

Writing Task 2 – Discussion Essay
Question: Some people believe remote work is beneficial, while others think office work is superior. Discuss both views.
Sample Band 8 Answer:
“The debate between remote and office work has intensified during recent years, particularly since the pandemic. While proponents of each approach present valid arguments, both working models offer distinct advantages.
Supporters of remote work emphasize flexibility and autonomy. While working from home, employees can design schedules around personal productivity patterns. For many professionals, this flexibility has improved work-life balance significantly. During the pandemic, companies that adopted remote work for extended periods reported sustained or increased productivity. Additionally, while commuting previously consumed hours daily, remote workers now utilize this time more productively.
Conversely, advocates for office work highlight collaboration and company culture. While remote communication tools exist, they cannot fully replicate spontaneous discussions that occur in physical offices. During in-person meetings, team members can read body language and build stronger relationships. For creative industries particularly, the collaborative energy of shared workspaces proves invaluable. During my own experience working in both environments for several years, I observed that complex problem-solving occurred more efficiently face-to-face.
While both approaches have merit, I believe hybrid models represent the optimal solution. For tasks requiring deep concentration, remote work proves ideal. However, during collaborative projects or strategic planning sessions, office attendance facilitates better outcomes. Companies should allow flexibility while maintaining regular in-person interaction.
In conclusion, rather than viewing these as opposing options, organizations should recognize that different tasks suit different environments. For the foreseeable future, successful companies will likely adopt flexible policies accommodating both preferences.”

- Balanced use of While for contrasting views
- During for time periods and situations

Lỗi Thường Gặp & Cách Sửa
Lỗi 1: Dùng During + Mệnh Đề
❌ SAI:
“During I was studying abroad, I learned many things.”
✅ ĐÚNG:
“While I was studying abroad, I learned many things.”
HOẶC
“During my time studying abroad, I learned many things.”
Giải thích:
During là giới từ, chỉ có thể theo sau bởi danh từ hoặc cụm danh từ. Khi muốn nối hai mệnh đề có động từ, phải dùng While (liên từ).
Cách nhận biết:
- Nhìn thấy “During” → Kiểm tra xem sau nó có động từ không
- Nếu có chủ ngữ + động từ → SAI → Đổi thành While
- Nếu chỉ có danh từ → ĐÚNG
Lưu ý:
Đây là lỗi phổ biến nhất của học viên Việt Nam vì trong tiếng Việt, “trong lúc/trong khi” có thể dùng cho cả hai trường hợp.
Lỗi 2: Dùng While + Danh Từ (không có động từ)
❌ SAI:
“While the meeting, we discussed the new project.”
✅ ĐÚNG:
“During the meeting, we discussed the new project.”
HOẶC
“While we were having the meeting, we discussed the new project.”
Giải thích:
While là liên từ, phải nối hai mệnh đề hoàn chỉnh (có chủ ngữ + động từ). Nếu chỉ có danh từ đơn thuần, phải dùng During.
Cách kiểm tra nhanh:
While + ??? → Hỏi: "Có động từ không?"
├─ CÓ → ĐÚNG (while I was working)
└─ KHÔNG → SAI (while the meeting) → Dùng During
Thêm ví dụ:
- ❌ “While my vacation…” → ✅ “During my vacation…”
- ❌ “While the pandemic…” → ✅ “During the pandemic…” (hoặc “While the pandemic was ongoing…”)
Lỗi 3: Nhầm Lẫn For Và Since
❌ SAI:
“I have lived here since 5 years.”
“I have lived here for 2019.”
✅ ĐÚNG:
“I have lived here for 5 years.” (khoảng thời gian)
“I have lived here since 2019.” (mốc thời gian)
Giải thích:
- FOR + duration (khoảng thời gian): for 3 hours, for 2 months, for 10 years, for a long time
- SINCE + point in time (mốc thời gian): since Monday, since 2020, since January, since I was a child
Quy tắc vàng:
Trả lời "How long?" (Bao lâu?)
├─ FOR + [số đếm] + [đơn vị thời gian]
└─ SINCE + [thời điểm cụ thể/mệnh đề quá khứ]
Bảng phân biệt:
| FOR | SINCE |
|---|---|
| for 2 weeks | since last week |
| for 5 years | since 2019 |
| for a long time | since childhood |
| for several months | since January |
| for ages | since I met you |
Lỗi 4: Dùng For + Danh Từ Sự Kiện
❌ SAI:
“I visited many museums for my vacation.”
“She learned a lot for the training program.”
✅ ĐÚNG:
“I visited many museums during my vacation.”
“She learned a lot during the training program.”
Giải thích:
For dùng cho độ dài thời gian (how long), không dùng cho sự kiện hoặc giai đoạn. Khi nói về một sự kiện/hoạt động cụ thể, dùng During.
So sánh:
- “I stayed in Paris for one week.” → Đúng (one week = duration)
- “I stayed in Paris during my vacation.” → Đúng (vacation = event)
- ❌ “I stayed in Paris for my vacation.” → Sai
Cách phân biệt:
- Hỏi “How long?” → FOR (for 3 days, for 2 hours)
- Hỏi “When?” → DURING (during the conference, during summer)
Lỗi 5: Vị Trí Dấu Phẩy Với While
❌ SAI:
“While I was studying my phone rang.”
“Some students prefer online learning while, others prefer traditional classes.”
✅ ĐÚNG:
“While I was studying, my phone rang.” (dấu phẩy sau mệnh đề While)
“Some students prefer online learning, while others prefer traditional classes.” (dấu phẩy trước while)
Giải thích:
Quy tắc dấu phẩy:
-
While ở đầu câu: Bắt buộc có dấu phẩy sau mệnh đề While
- “While I was cooking, the doorbell rang.”
-
While ở giữa câu (chỉ thời gian đồng thời): Thường không cần dấu phẩy
- “I listened to music while I worked.”
-
While ở giữa câu (chỉ sự tương phản): Cần dấu phẩy trước While
- “Some people love summer, while others prefer winter.”
Mẹo:
- While = “trong khi” (đồng thời) → không cần dấu phẩy
- While = “trong khi đó/ngược lại” (tương phản) → cần dấu phẩy
Lỗi 6: Dùng During Với Động Từ Kéo Dài
❌ SAI:
“I was sleeping during 8 hours.”
“The meeting continued during 3 hours.”
✅ ĐÚNG:
“I slept for 8 hours.”
“The meeting continued for 3 hours.”
Giải thích:
Khi nói về độ dài thời gian của một hành động, luôn dùng For, không dùng During. During chỉ dùng khi nói về thời điểm/sự kiện.
So sánh:
- “The meeting lasted for 3 hours.” → Cuộc họp kéo dài 3 tiếng (độ dài)
- “During the meeting, we discussed many topics.” → Trong buổi họp, chúng tôi thảo luận nhiều chủ đề (thời điểm)
Lỗi 7: Thì Động Từ Không Phù Hợp Với For
❌ SAI:
“I live here for 5 years.” (Present Simple với for)
“I am living here for 5 years.” (Present Continuous với for – thời gian dài)
✅ ĐÚNG:
“I have lived here for 5 years.” (Present Perfect)
“I lived there for 5 years.” (Past Simple – đã kết thúc)
Giải thích:
Khi dùng For với khoảng thời gian kéo dài đến hiện tại, phải dùng Present Perfect (have/has + V3), không dùng Present Simple hay Present Continuous.
Quy tắc:
- Hành động bắt đầu trong quá khứ, tiếp tục đến hiện tại → Present Perfect + for
- Hành động đã kết thúc trong quá khứ → Past Simple + for
Lỗi 8: Nhầm While Và When
❌ SAI (trong một số ngữ cảnh):
“While I arrived home, it started raining.”
✅ ĐÚNG:
“When I arrived home, it started raining.”
HOẶC
“While I was walking home, it started raining.”
Giải thích:
- While dùng với hành động kéo dài (continuous): while I was doing
- When dùng với hành động ngắn, đột ngột: when I arrived, when it happened
So sánh:
- “While I was reading, the phone rang.” → Đúng (reading = kéo dài)
- “When the phone rang, I was reading.” → Đúng (rang = đột ngột)
- ❌ “While the phone rang…” → Thường sai (rang = hành động ngắn)
Lỗi 9: Dùng During Với Động Từ Thay Vì Danh Từ Hóa
❌ SAI:
“During study abroad, I learned a lot.”
“During travel to Europe, we visited many cities.”
✅ ĐÚNG:
“During my time studying abroad, I learned a lot.”
“During our trip to Europe, we visited many cities.”
Giải thích:
Sau During phải là danh từ hoàn chỉnh, không phải động từ nguyên mẫu. Nếu muốn giữ ý nghĩa động từ, cần danh từ hóa (gerund/noun phrase).
Cách sửa:
- study → my studies / my time studying / the study period
- travel → my trip / my travels / the journey
- work → my work / my job / the working period
Lỗi 10: Sử Dụng Thừa Cả During Và For
❌ SAI:
“During for two weeks, I stayed in Bangkok.”
“I worked there during for 5 years.”
✅ ĐÚNG:
“For two weeks, I stayed in Bangkok.”
HOẶC
“During those two weeks, I stayed in Bangkok.”
Giải thích:
During và For có vai trò khác nhau, không dùng cùng lúc. Chọn một trong hai tùy theo ngữ cảnh.
Quy tắc chọn:
- Có con số thời gian (2 weeks, 5 years) → FOR
- Có tên sự kiện/giai đoạn (the conference, summer) → DURING
- Nếu cả hai đều có thể → Chọn theo ý muốn nhấn mạnh gì

“I would like to talk about my experience studying abroad during my university years. I lived in Australia for two years, from 2018 to 2020.
During the first few months, I experienced severe homesickness. While my classmates were enjoying their new freedom, I was struggling to adapt. During this difficult period, I called my parents almost every day.
However, during the second semester, things improved significantly. While I was attending classes, I started making friends with international students. We formed a study group that met for three hours every weekend.
During my time there, I traveled extensively around Australia. During the university holidays, I visited Sydney, Melbourne, and the Great Barrier Reef. These trips usually lasted for one or two weeks.

Đáp Án Bài Tập 5 – Sample Answer
Sample Band 8 Response:
“Technology has fundamentally transformed education during the past two decades. For many years, traditional teaching methods dominated classrooms, but digital tools have now become indispensable.
While older generations relied entirely on textbooks and lectures, today’s students access vast knowledge repositories online. During lessons, teachers incorporate multimedia presentations, interactive applications, and virtual simulations. This technological integration has proven particularly valuable during the recent pandemic, when schools operated remotely for extended periods.
However, while technology offers unprecedented access to information, it cannot entirely replace human instruction. During online classes, many students struggle with motivation and lack the personal connection that physical classrooms provide. For subjects requiring hands-on practice or collaborative learning, digital platforms remain inadequate.
Therefore, while embracing technological advances, educational institutions must maintain a balanced approach that combines digital innovation with traditional pedagogical methods. For the foreseeable future, the most effective education will integrate both approaches thoughtfully.” (152 words)
Analysis:
- During: 4 times (naturally integrated)
- While: 4 times (showing both simultaneous actions and contrasts)
- For: 4 times (showing duration)
- Band 8+ features: complex sentences, academic vocabulary, clear argument structure
Đáp Án Bài Tập 6 – Sample Speaking Answers
Part 1 Answers:
Q1: How long have you been learning English?
“I’ve been learning English for over 12 years now, actually since primary school. During my early years, I focused mainly on grammar and vocabulary, but during high school, I started practicing speaking more seriously. While I was at university, I took IELTS preparation courses, and that’s when my English really improved.”
Q2: What do you usually do during your free time?
“During my free time, I enjoy reading and watching movies. While I’m reading, I prefer quiet environments like libraries or cafes. I also exercise for about an hour every day. While some people prefer going to gyms, I like jogging outdoors, especially during the early morning.”
Q3: Do you prefer studying while listening to music, or in silence?
“It depends on the task, actually. While I’m doing simple work like organizing notes or reviewing vocabulary, I listen to instrumental music. However, during intensive study sessions, especially while I’m working on complex problems, I need complete silence. I’ve noticed that for the past few years, I’ve become more sensitive to noise while studying.”
Part 2 Sample (First 60 seconds):
“I’d like to talk about a trip I took to Japan two years ago. I stayed there for two weeks during the spring season, specifically in April.
During my time in Japan, I visited several cities including Tokyo, Kyoto, and Osaka. While I was in Kyoto, I had the opportunity to see beautiful cherry blossoms in full bloom. During this period, many parks and temples were filled with both tourists and locals enjoying hanami, which is the traditional practice of viewing flowers.
While traveling, I stayed in various accommodations. For the first week, I stayed in a traditional ryokan, and while I was there, I experienced authentic Japanese hospitality. During the second week, I moved to a modern hotel in Tokyo…”
Part 3 Sample Answer:
Q: How has tourism changed during the past decade?
“Tourism has undergone dramatic changes during the last decade, primarily due to technology. For instance, while travelers previously relied on guidebooks and travel agencies, they now use smartphones and apps for planning. During recent years, we’ve also seen the rise of sustainable tourism. While some tourists prioritize cheap travel, others are willing to pay more for eco-friendly options. During the pandemic, the industry faced unprecedented challenges, and for nearly two years, international travel virtually stopped. However, while recovery has been slow, during 2023 and 2024, we’ve witnessed tourism rebounding strongly.”
