📖 The Question#
The diagrams below show how glass containers, such as bottles, are produced and recycled.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

Use “chart” if the question contains no pictures, and “diagram” if it does.
🏆 The Essay#
Introduction (引言)#
The first flow chart/diagram illustrates the process of glass container production, and the second diagram shows steps in the process of recycling used glass.
Overview (概述)#
We can see that glass is made using three main raw materials, and that the manufacturing process consists of four distinct stages. It is also clear that five steps are required to turn used glass into new glass products.
Body Paragraph 1 (細節段落 1)#
At the first stage in the production of glass, sand, soda ash, limestone and other chemicals are mixed together. Next, this mixture is heated in a glass furnace at approximately 1500℃ to produce molten glass. Finally, the molten glass can then be shaped, by blowing, to create the end products, namely glass containers.
Body Paragraph 2 (細節段落 2)#
Glass recycling begins with the collection of used glass products. After that, the collected glass is sorted according to its colour, and then washed in order to remove any impurities. At the fourth stage of recycling, the glass is crushed and melted, and the resulting molten glass can finally be moulded to create new items.
🔑 Collocations & Vocabulary (亮點單字與片語)#
- Flow diagram / illustrates：流程圖 / 描繪（替代 shows 的高分詞）
- Consists of four distinct stages：由四個不同階段組成
- Raw materials：原材料（如 sand, soda ash, limestone）
- Molten glass：熔融玻璃（玻璃融化後的專業術語）
- By blowing：透過吹製（玻璃成形的專業方法）
- Sorted according to its colour：根據顏色分類（回收流程關鍵動詞片語）
- In order to remove impurities：為了去除雜質（目的狀語高分表達）
- Crushed and melted：壓碎並熔化（回收核心動詞）
- Moulded：模製（回收最終成形動詞）
- Namely：即（用於舉例或補充說明的連接詞）
💡 The Strategy (流程圖解題 4 步曲)#
1. 📝 Paraphrase (改寫題目)#
處理 Diagram / Flow Chart 時，引言要清楚指出「有幾張圖」以及「各自說明什麼」。利用 illustrates 和 shows 區分兩者的功能。
- 高分句型：
The first diagram illustrates [Process 1], and the second diagram shows [Process 2].
2. 🌟 Overview (找出全貌與核心趨勢)#
流程圖的 Overview 要抓出「總共有幾個步驟」以及「起點與終點」。如果是兩張圖，每張圖寫一句核心流程總覽。
- 高分句型：
We can see that [Process 1 has X stages]. It is also clear that [Process 2 requires Y steps].
3. 📊 Details Paragraphs (步驟分組與描述)#
流程圖的描述重點在於「步驟順序」與「關鍵動作」，不必比較數據。每張圖獨立成段，按時間／順序連接詞依序描述。
- Detail 1（生產）： 從混合原料 → 加熱成熔融玻璃 → 吹製成形。
- Detail 2（回收）： 從收集 → 分類 → 清洗 → 壓碎熔化 → 模製新產品。
4. 🔤 Essential Vocabulary (必備流程圖字彙)#
流程圖要拿高分，必須熟練使用「步驟順序連接詞」與「被動語態」來描述動作。
- 順序連接詞：
At the first stage,Next,Then,After that,Finally,At the fourth stage - 被動語態高分結構：
are mixed,is heated,can be shaped,is sorted,are washed,is crushed and melted,can be moulded - 動作代稱替換：
the mixture,the molten glass,the collected glass,the resulting molten glass - 目的表達：
in order to,to,so that（用於解釋每一步驟的目的）
