HƯỚNG DẪN VIẾT BÀI

Noise Pollution (City vs Rural, Day vs Night)

1. Hiểu đề bài

Biểu đồ cho thấy số người (triệu người) bị ảnh hưởng bởi 4 nguồn tiếng ồn: Traffic, Train, Aircraft, Industry — ở city và rural, vào ban ngày và ban đêm. Có 3 layer: location (city vs rural) / time (day vs night) / source (4 loại) → chỉ chọn ý nổi bật.

2. Cách viết Overview

Traffic là nguồn lớn nhất trong mọi trường hợp
City luôn cao hơn rural
Day luôn cao hơn night
Industry gần như không đáng kể, đặc biệt ở rural

3. Cách chia Body

BODY 1 – City

Traffic: 64 → 48 (giảm nhưng vẫn cao nhất)
Train: 10 → 8
Aircraft: 4 → 1
Industry: 1 → 0.25

BODY 2 – Rural

Traffic: 34 → 24
Train: 8 → 6
Aircraft: 2 → 1
Industry: 0 → 0 (không đáng kể)

be affected by noise / dominant source / negligible / minimal
figures in urban areas were consistently higher than those in rural areas

The charts compare the number of people affected by four types of noise pollution during the day and at night in urban and rural areas, measured in millions.

Overall, traffic was by far the dominant source of noise in both settings, while industrial noise affected the fewest people. In all cases, more individuals were impacted during the day than at night, and urban figures were consistently higher than those in rural areas.

In cities, traffic noise affected 64 million people during the day, decreasing to 48 million at night. Train noise was the second most significant source, impacting 10 million people by day and 8 million at night. Aircraft noise dropped sharply from 4 million to 1 million, while industrial noise was minimal, at just 1 million during the day and 0.25 million at night.

In rural areas, the same pattern is evident but at lower levels. Traffic affected 34 million people during the day and 24 million at night. Train noise declined from 8 to 6 million, and aircraft noise from 2 to 1 million. Industrial noise had no impact in rural areas at either time.
