TASK 1 (Mixed charts): GLOBAL WATER USE
 |
Sample Answer
The provided line graph illustrates global water consumption among three major sectors, while the table presents data about water usage in Brazil and Congo.
Overall, water consumption across all sectors saw increases to varying degrees, with agricultural practices consistently accounting for the largest amount of water. This area was followed distantly by industrial and domestic usage, both of which showed more modest rises.
Regarding consumption patterns in Brazil and Congo in the year 2000, the former, which was far more populated and possessed an overwhelmingly larger area of irrigated land, recorded disproportionately higher water consumption in cubic metres per head than the latter. Looking initially at global consumption, agricultural endeavours accounted for around 500 cubic kilometres of water in 1900, far surpassing the figures for industrial and domestic usage, both of which stood at close to zero. By 2000, the quantity of water used for farming purposes rose markedly and steadily, peaking at roughly 3,000 cubic kilometres, marking a nearly six-fold increase. A largely similar trend, albeit less pronounced, was observed in industrial water consumption, whose figure was stable until 1950, when it experienced a dramatic increase to over 1,000 cubic kilometres by 2000, around a third of that for agriculture in the same year. Meanwhile, the trend for domestic use was relatively flat until 1980, when there was a modest rise to around 400 cubic kilometres.
Turning to water usage patterns in Brazil and Congo in 2000, Brazil, with a population of 176 million and 26,500 square kilometres of irrigated land, consumed nearly 360 cubic metres of water per person. Meanwhile, the Democratic Republic of Congo, with a roughly 30-times smaller population and an area of irrigated land that was a fraction of that of Brazil, consumed only 8 cubic metres per person in 2000, indicating a positive correlation between population, farming land, and water usage patterns.

Tóm tắt cấu trúc:
1. Introduction – Mở bài
→ Paraphrase đề bài / biểu đồ
(Không nêu số liệu)
2. Overview – Tổng quan
→ Nêu xu hướng chính (không chi tiết)
- Nhóm 1: xu hướng chung (global)
- Nhóm 2: so sánh 2 nước (Brazil vs Congo)
3. Body Paragraph 1 – Số liệu biểu đồ 1 (line graph)
→ Global trends – xu hướng toàn cầu
- Tập trung vào agriculture trước (largest)
- Sau đó industrial → domestic
- Dùng mốc thời gian + thay đổi lớn
→ Gộp thông tin theo xu hướng, không theo năm
4. Body Paragraph 2 – Số liệu bảng (table)
→ Brazil vs Congo
- Population → irrigated land → water use
- Logic: Nhiều người + nhiều đất canh tác = dùng nhiều nước
→ Kết nối: correlation (tương quan)
Mini-Template
Intro:
The provided graph/table illustrates…

Overview:
Overall, A increased, while B/C were lower and rose more modestly.
→ Tổng quan: A tăng mạnh nhất, B/C tăng nhẹ
Regarding Brazil and Congo, the former consumed far more water…
→ Về Brazil & Congo: Brazil dùng nhiều nước hơn hẳn.
Body 1 (Global trends):
Agricultural water use rose sharply from X to Y…

Industrial use remained low until… then grew significantly…
→ Công nghiệp tăng chậm, rồi tăng mạnh
Domestic use stayed flat before a slight rise…
→ Sinh hoạt ban đầu ổn định, sau tăng nhẹ
Body 2 (Countries compare):
Brazil, with a far larger population and irrigated land, consumed…
→ Brazil dân đông + nhiều đất tưới = dùng nhiều nước
In contrast, Congo… only used…
→ Trong khi Congo chỉ dùng rất ít…
This indicates a strong correlation…
→ Cho thấy mối tương quan rõ rệt…
Key Linking Language (Nên học thuộc)
- Regarding… (Về…)
- In contrast… (Ngược lại…)
- By comparison… (So sánh mà nói…)
- Meanwhile… (Trong khi đó…)
- This indicates that… (Điều này cho thấy…)
Tư duy gộp nhóm thông tin – Grouping Logic
📌 Không kể từng năm → kể theo xu hướng lớn:
- Agriculture: tăng mạnh & sớm nhất
- Industry: ổn định → tăng mạnh (từ 1950)
- Domestic: phẳng → tăng nhẹ
📌 Không kể từng dòng số & bảng → rút ra pattern:
- Brazil > Congo vì:
Population ↑ + Irrigated land ↑ = Water use ↑
