1\. Giải thích đề

Biểu đồ đường cho thấy tỷ lệ sinh (trên 1.000 phụ nữ) ở 6 nhóm tuổi trong giai đoạn 1973–2008.

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

2\. Introduction (paraphrase)

The line graph illustrates birth rates among six different age groups between 1973 and 2008\.

3\. Overview (ý chính)

Nhóm 25–29 luôn cao nhất, dù có biến động
20–24 giảm đều theo thời gian
30–34 và 35–39 tăng đáng kể
Under 20 và 40+ đều giảm liên tục
Xu hướng chung: dịch chuyển sinh con sang nhóm tuổi lớn hơn

4\. Cách chia BODY

→ Chia theo giảm vs tăng \+ nhóm nổi bật

BODY 1 – Nhóm cao & giảm (25–29, 20–24)

25–29:

→ bắt đầu khoảng 140 (1973)

→ giảm rồi tăng lại (peak \~134 năm 1993\)

→ kết thúc khoảng 120

→ luôn cao nhất

20–24:

→ giảm đều từ \~130 xuống \~90

→ Key idea:

Nhóm trẻ (20–29) từng chiếm ưu thế, nhưng 20–24 giảm rõ rệt

BODY 2 – Nhóm tăng & nhóm thấp

30–34:

→ tăng đều từ \~70 lên \~87

35–39:

→ tăng mạnh từ \~40 lên \~65

Under 20:

→ giảm từ \~60 xuống \~37

40+:

→ giảm liên tục từ \~20 xuống \~5

→ Key idea:

Nhóm 30+ tăng rõ rệt, trong khi nhóm rất trẻ và rất lớn tuổi giảm

Ví dụ câu:

The 25–29 group remained the highest despite some fluctuations.
Birth rates among women aged 20–24 declined steadily.
In contrast, the figures for the 30–34 and 35–39 groups increased significantly.

The line graph illustrates birth rates per 1,000 women across six age groups between 1973 and 2008\.

Overall, women aged 25–29 consistently recorded the highest birth rates, although their figures fluctuated slightly. In contrast, the youngest (under 20\) and oldest (40 and over) groups experienced steady declines. Meanwhile, birth rates for women aged 30–34 and 35–39 increased over time, indicating a shift towards later childbearing.

In 1973, the highest rate was among women aged 25–29 at about 140 births per 1,000, followed by those aged 20–24 at around 130\. Both groups declined over the period, with the 20–24 group falling more steadily to approximately 90 by 2008\. The 25–29 group fluctuated, peaking again at around 135 in 1993 before settling at about 120 in the final year.

By contrast, the 30–34 group rose consistently from roughly 70 in 1973 to about 87 in 2008\. Similarly, the 35–39 group increased from around 40 to approximately 65, with the most notable growth occurring after 1988\.

The under-20 group declined gradually from about 60 to under 40, while the 40-and-over group fell steadily from around 20 to just 5 births per 1,000 women by 2008\.
