Tóm tắt

Có nhiều cách hơn "because" để đưa ra lý do — và dùng đúng cách trong đúng ngữ cảnh là điểm khác biệt giữa Band 6 và Band 7+:

Nhóm Patterns Theo sau là
Cơ bản (clause) because, since, as Subject + Verb
Giới từ (noun phrase) because of, due to, owing to Noun / Noun phrase
Trang trọng (clause) given that, seeing as, in that Subject + Verb
Kết quả (đầu câu) therefore, consequently, as a result
Giải thích thêm this is because, the reason is that

Tại sao quan trọng

Trong IELTS Writing Task 2, mỗi luận điểm cần được hỗ trợ bằng lý do rõ ràng. Một lý do được trình bày tốt gồm: Claim (luận điểm) + Reason (lý do) + Evidence/Example (bằng chứng). Trong Speaking Part 3, examiner đánh giá khả năng bạn giải thích, lập luận, và defend quan điểm.

Nếu chỉ biết dùng "because", câu viết sẽ đơn điệu và bị trừ điểm Grammatical Range.


NHÓM 1: BECAUSE, SINCE, AS — liên từ chỉ nguyên nhân (+ clause)

Cả ba đều nối mệnh đề nguyên nhân với mệnh đề chính.

BECAUSE — phổ biến nhất, rõ ràng nhất

[Main clause] because [S + V]
Because [S + V], [Main clause]
  • People avoid exercise because they lack time and motivation.
  • Because regular physical activity improves mental health, it should be encouraged in schools.

"Because" nhấn mạnh nguyên nhân trực tiếp — dùng khi muốn nêu rõ lý do cụ thể.

SINCE — lý do đã biết, được chấp nhận

Since [S + V], [Main clause]
[Main clause] since [S + V]
  • Since healthcare is a basic human right, governments have a responsibility to fund it.
  • The policy is controversial, since it disproportionately affects low-income households.

"Since" ngụ ý lý do đã được công nhận chung — phổ biến trong IELTS Writing học thuật.

AS — trang trọng, thường đứng đầu câu

As [S + V], [Main clause]
  • As urban populations continue to grow, pressure on infrastructure intensifies.
  • As the evidence suggests, early intervention is far more effective than later treatment.

"As" trang trọng hơn "because" một chút — phù hợp Writing Task 2 hơn Speaking.


NHÓM 2: BECAUSE OF, DUE TO, OWING TO — giới từ (+ noun phrase)

BECAUSE OF — phổ biến nhất, không trang trọng lắm

[Main clause] because of [noun phrase]
Because of [noun phrase], [Main clause]
  • Many students struggle because of a lack of access to quality resources.
  • Because of rising living costs, young people are postponing major life decisions.

DUE TO — trang trọng, thường gặp trong học thuật

[Main clause] due to [noun phrase]
Due to [noun phrase], [Main clause]
  • The project was delayed due to unforeseen technical difficulties.
  • Due to rapid urbanisation, rural communities are losing their cultural identity.

"Due to" thường dùng để giải thích kết quả đã xảy ra — phổ biến trong Task 1 và Task 2 Writing.

OWING TO — rất trang trọng, thường đứng đầu câu

Owing to [noun phrase], [Main clause]
  • Owing to a significant rise in demand, manufacturers have had to increase production.
  • Owing to budget constraints, the project was scaled back considerably.

NHÓM 3: GIVEN THAT, SEEING AS — trang trọng và nâng cao (+ clause)

GIVEN THAT — vì (đã biết rằng), lý do dựa trên thực tế đã được thiết lập

Given that [S + V], [Main clause]
[Main clause], given that [S + V]
  • Given that climate change poses an existential threat, immediate action is not optional.
  • The decision seems reasonable, given that resources are severely limited.
  • Given that many students now learn online, schools need to adapt their teaching methods.

"Given that" = "considering the fact that" — ngụ ý lý do là thực tế đã rõ, không cần tranh luận.

SEEING AS / SEEING THAT — vì, bởi vì (thân mật hơn given that)

Seeing as [S + V], [Main clause]
  • Seeing as you've already started the project, it makes sense to continue.
  • Seeing as the economy is struggling, job creation should be the priority.

"Seeing as" trang trọng hơn "because" nhưng ít formal hơn "given that" — phù hợp Speaking Part 3.

IN THAT — theo nghĩa rằng, ở chỗ (giải thích cụ thể hơn)

[Main clause] in that [S + V]
  • The policy is flawed in that it fails to address the root causes of poverty.
  • This approach is effective in that it targets the most vulnerable populations directly.

"In that" = "in the sense that / because specifically" — rất học thuật, phù hợp Task 2.


NHÓM 4: RESULT CONNECTORS — kết quả của lý do (đứng đầu câu)

Khi muốn bắt đầu câu bằng kết quả rồi mới nêu lý do ngầm định, dùng:

Connector Ví dụ
Therefore Population is ageing rapidly. Therefore, healthcare spending will inevitably increase.
Consequently Investment fell sharply. Consequently, thousands of jobs were lost.
As a result Air pollution worsened. As a result, respiratory diseases became more common.
Hence Demand increased. Hence, prices rose.
Thus Data was inconclusive. Thus, further research is required.

NHÓM 5: "THIS IS BECAUSE..." — giải thích nguyên nhân sau khi nêu luận điểm

Pattern này rất hữu ích trong Writing Task 2 để tách luận điểm và lý do:

[Claim/Statement]. This is because [S + V].
[Claim/Statement]. The reason (for this) is that [S + V].
[Claim/Statement]. One key reason is that [S + V].
[Claim/Statement]. This can be attributed to [noun phrase].
  • Obesity rates have risen sharply in recent decades. This is because diets have become increasingly dominated by processed, calorie-dense foods while physical activity has declined.

  • Young people today report higher levels of anxiety than previous generations. The reason for this is partly the pressure of social media comparison and partly the economic uncertainty they face.

  • Many students perform poorly in exams despite spending long hours studying. This can be attributed to ineffective study techniques rather than a lack of effort.


CÁCH XÂY DỰNG LUẬN ĐIỂM CÓ LÝ DO (IELTS Writing Task 2)

Framework: Claim → Reason → Evidence/Example

[Topic sentence / Claim]
[Reason — why is this true?]
[Evidence or example — what shows this?]
[Result or implication — so what?]

Ví dụ đoạn văn hoàn chỉnh:

"One significant benefit of higher education is improved career prospects. This is because universities equip graduates with both specialised knowledge and transferable skills such as critical thinking and communication. For instance, a study by the OECD found that degree holders earn, on average, 56% more than those with only secondary-level qualifications. As a result, access to higher education can be a powerful tool for reducing socioeconomic inequality."

Phân tích: Claim (improved career prospects) + Reason (because universities equip graduates) + Evidence (OECD study) + Result (reduce inequality).


SPEAKING — đưa lý do trong Part 3

Trong Speaking Part 3, đưa lý do theo kiểu thân mật hơn — tránh quá cứng nhắc:

Writing Speaking tương đương
This is because Well, the main reason is... / I think it's because...
Due to rapid urbanisation Because cities are growing so fast...
Given that resources are limited Since/As we don't have unlimited resources...
Consequently So... / As a result...
This can be attributed to It's mostly down to... / It has a lot to do with...

Part 3 example: - Q: "Why do you think young people are less likely to vote than older people?" - ✅ "I think the main reason is that many young people feel disconnected from the political process — as if their vote doesn't actually make a difference. And also, young adults are often dealing with so many immediate pressures, like education and employment, that politics feels distant. On top of that, political messaging is rarely targeted at younger demographics in a way that resonates with them."

  • ❌ The project failed due to the team was underfunded.

Lỗi 3: "This is because" mà không có câu trước

  • ❌ Bắt đầu đoạn văn bằng "This is because..."
  • ✅ "This is because" phải theo sau một statement đã nêu trước đó.

Lỗi 4: Nêu lý do nhưng không develop

  • ❌ "Governments should invest in education because it is important."
  • ✅ "Governments should invest in education because it is the most effective way to equip citizens with the skills needed to adapt to a rapidly changing economy — and ultimately drives long-term growth."
