1\. Giải thích đề

Biểu đồ đường cho thấy số người sử dụng (trên 100 dân) của 5 loại dịch vụ liên lạc:

landline
cellular phone
internet
fixed broadband
mobile broadband

trong giai đoạn 1998–2008.

→ Dạng: line graph (time \+ multiple categories)

2\. Introduction (paraphrase)

The line graph illustrates the number of people per 100 inhabitants using five different communication services between 1998 and 2008\.

3\. Overview (ý chính)

Cellular phone tăng mạnh nhất và trở thành phổ biến nhất
Internet tăng đều đáng kể
Landline tăng nhẹ rồi chững/lệch nhẹ cuối kỳ
Broadband (fixed & mobile) xuất hiện muộn nhưng tăng nhanh

4\. Cách chia BODY

→ Chia theo tăng mạnh vs tăng nhẹ/late development

BODY 1 – Cellular phone, Internet, Landline

Cellular phone:

→ tăng mạnh từ \~4 lên \~63

→ vượt tất cả các dịch vụ khác

Internet:

→ tăng đều từ \~3 lên \~23

→ không có giảm

Landline:

→ tăng nhẹ từ \~13 lên \~19 (2006)

→ sau đó giảm nhẹ về \~18 (2008)

→ Key idea:

Mobile phone bùng nổ, internet tăng ổn định, landline gần như bão hòa

BODY 2 – Fixed & Mobile broadband

Fixed broadband:

→ bắt đầu khoảng 2002 (\~0)

→ tăng lên \~5 (2008)

Mobile broadband:

→ gần như 0 đến 2006

→ tăng lên \~3 (2008)

→ Key idea:

Cả hai xuất hiện muộn nhưng tăng nhanh ở cuối giai đoạn

Ví dụ câu:

Cellular phone service experienced the most dramatic growth.
Landline usage remained relatively stable before a slight decline.
Broadband services emerged later but increased rapidly towards the end.

The line graph illustrates the number of people per 100 inhabitants using five types of communication services—landline, cellular phone, internet, fixed broadband and mobile broadband—between 1998 and 2008\.

Overall, cellular phone usage rose dramatically and became the most widely used service by the end of the period. Internet and broadband services also showed strong growth, while landline usage remained relatively stable with a slight decline in the final years.

In 1998, landline service was the most common, at around 13 users per 100 people, followed by cellular phones at approximately 4\. Over the next decade, landline usage increased modestly to about 19 in 2006 before falling slightly to 18 in 2008\. In contrast, cellular phone usage surged steadily, reaching around 17 in 2002, then climbing sharply to over 60 by 2008\.

Internet usage also rose consistently, from roughly 3 users in 1998 to about 23 in 2008\. Fixed broadband appeared later, starting at virtually zero in 2002 and increasing gradually to around 5 users by the end of the period. Mobile broadband emerged even later, remaining negligible until 2006 before rising slightly to approximately 3 users in 2008\.
