1Chart: Hong Kong Population. The bar chart shows how the population of Hong Kong changed between 2020 and 2024. In 2020, the population stood at 7.50 million. It fell to 7.41 million in 2021, and then to 7.34 million in 2022. In 2023 the figure was 7.27 million. By 2024, it had dropped further to 7.20 million. The figures come from a recent study.
2In other words, the population has been dropping for five years. The biggest drop was between 2020 and 2021, when about ninety thousand people left the city. After that, the decline became slightly gentler, but the downward trend continued. Experts say emigration and low birth rates are the main causes. A line showing the average of the past ten years would make the fall even clearer.
3Many young families moved abroad, while fewer babies were born each year. Some parents delay having children because of high housing costs and long working hours. The trend worries schools, which now face shrinking classes and even closures. Shops and restaurants also feel the effect, as there are fewer customers to serve. If you read the chart carefully, the message is clear: action is needed.

3逐步講解 Steps
- 標題讀圖表第一步是讀標題,考點是先確認圖表主題與資料來源。方法是把標題、副題與註腳都掃一遍。以課文為例,這幅棒形圖題為 Hong Kong Population 2020-2024,數據來自一項近期研究,來源是否可靠須先查證。易錯之處是學生跳過標題直接讀數字,連圖表講什麼都不知道便開始計算;標題決定解讀框架,來源決定可信程度,兩者都是答題時可以引用的資訊,掃標題只須數秒,收益卻是全局。
- 軸第二步是讀軸,考點是單位辨認,這是圖表題最大的失分位。方法先看橫軸縱軸各代表什麼,再確認單位。以課文為例:橫軸是年份,縱軸以 million 為單位,7.50 即七百五十萬人;million、percent 與千人是三個常見陷阱。易錯之處是學生把 million 讀成萬,數字放大十倍,整題答案全錯;單位一錯,後面的趨勢描述與計算全部作廢,讀軸的幾秒鐘絕不能省,這是最便宜的保險。
- 圖例圖例說明每種顏色或圖案代表哪組數據,考點是對號入座。方法是在讀任何數字之前,先將每條棒與圖例逐一配對。以課文為例,單一組數據的棒形圖較簡單,但雙組數據的圖表若選錯顏色,便會答成另一組資料,全題作廢。易錯之處是學生假設左邊永遠是第一組數據;不同圖表的排列未必一致,配對圖例是唯一的保險做法,尤其在男女、新舊、本地與外地對照的圖表之中,顏色配錯便南轅北轍。
- 趨勢第三步是讀趨勢,考點不是只找最高最低,而是描述整體方向與變化節奏。方法是逐年比較數字。以課文為例:人口由 7.50、7.41、7.34、7.27 逐年降至 7.20 百萬,連續五年向下;最大跌幅出現在二零二零至二零二一年,約九萬人離開,其後放緩但方向不變。易錯之處是學生只答有升有跌或大致向下,忽略跌勢先急後緩的節奏變化;趨勢描述包括方向、幅度與節奏三個層次,答題時三項兼顧。
- 找焦點圖表故事的焦點通常是最大變化所在,考點是把數據與文字解釋接駁。方法是先鎖定變化最陡的年份,再到文中找原因。以課文為例,跌幅最急的二零二零至二零二一年正是考點所在,文中解釋原因為移民與低出生率,並以學校縮班、商戶少客說明影響。易錯之處是學生只會讀數不會說故事;圖表問的是 so what,數字背後的原因與影響才是進階題目的答案所在,讀圖的最終目的是讀懂故事。
- 數字背後高階圖表題要求讀出數字背後的現實意義,考點是把統計聯繫到生活。方法是把數據變化逐項對應到具體場景。以課文為例:人口下降意味着學校面對縮班甚至停辦,餐廳少了一批顧客,年輕家庭因樓價與工時延遲生育;圖表與文字合讀,才能讀懂完整故事。易錯之處是學生答題只羅列數字,沒有闡述意義;數據與現實之間的橋樑正是高分答案與普通答案的分界,練習時宜多問一句這意味着什麼。
- 答題格式趨勢題的答題格式是方向加數據,考點是答案的完整性。方法是先講方向,再引具體數字與年份。以課文為例:The population fell from 7.50 million to 7.20 million between 2020 and 2024,方向、起點、終點、時段一應俱全,才是滿分寫法。易錯之處是學生只寫人口下跌,沒有數據支持;評卷準則通常要求數字證據,空講方向只取得一半分數,引用數據的習慣須在練習中養成,寧多引一個數字,不可空口講白話。
5例題示範 Example
用「標題 → 軸 → 趨勢 → 數據」四步讀這個香港人口棒形圖,講出 2020 至 2024 年的整體趨勢和最大變化。
- 第一步:標題講明主題:香港人口 2020-2024;同時留意數據來源是否可靠。
- 第二步:看軸:X 軸是年份,Y 軸以百萬為單位,7.50 即 750 萬,不要讀錯單位。
- 第三步:趨勢:7.50 → 7.41 → 7.34 → 7.27 → 7.20 百萬,連續五年向下。
- 第四步:最大變化:2020 至 2021 跌得最多(約九萬人離開),之後放緩但方向不變。
- 第五步:讀背後故事:移民加低出生率是原因;學校縮班、商戶少客是影響。
- 答案:第一步看標題:棒形圖講香港人口 2020 至 2024 變化,並留意數據來源。第二步看軸:X 軸年份,Y 軸以百萬為單位,7.50 即 750 萬,不要讀錯。第三步看趨勢:人口由 7.50 百萬連跌至 7.20 百萬,五年減少約三十萬。第四步找重點:最大跌幅在 2020 至 2021 年,約九萬人離開,之後放緩但方向不變。原因是移民加低出生率,影響是學校縮班、商戶少客。讀圖四步——標題、軸、趨勢、數據——一分鐘講完整個故事。

8重點回顧 Recap
- 讀圖四步:標題 → 軸(單位)→ 圖例 → 趨勢。
- 單位陷阱:million、percent、千人,讀錯全題錯。
- 不要只看最高最低,要講趨勢:連升、連跌還是大幅波動。
- 找最大變化位(跌幅最大那年),才是數據故事的焦點。
- 數字背後有人:查來源、問原因、想影響,才算讀得懂。
