IELTS Writing Task 1 Process Diagrams with Sample Answers

Let's break down how to effectively approach a process chart in the IELTS Writing Task 1. I'll provide a step-by-step guide, covering planning, writing, and revision.

I. Understanding the Task & Process Charts

1. Recognize the Task Type: A process chart or diagram illustrates a series of steps or stages in a process. These can be natural, mechanical, or manufacturing processes.

2. Understand the Purpose: Your goal isn't just to list steps; it's to describe the process clearly and logically, using appropriate vocabulary and grammar. You're assessed on how well you can communicate the information in a structured, cohesive way.

3. Identify Key Features: Look for the following:

   • Starting Point: Where does the process begin?

   • Ending Point: Where does it finish?

   • Number of Stages: How many distinct steps are involved?

   • Direction of Flow: Is there a clear sequence (e.g., using arrows)?

   • Main Activities: What are the key actions in each stage (e.g., mixing, heating, collecting)?

   • Equipment/Materials: Are there specific machines or substances involved?

II. Planning Your Response (5-7 minutes)

1. Analyze and Note: Spend a few minutes to understand the flow, identify key stages, and think about the vocabulary you need. Jot down main ideas, transition words, and any specific terms you might use.

2. Structure Your Answer: Plan the layout as follows:

   • Introduction (1 sentence): State what the diagram shows.

   • Overview/General Statement (1 sentence): Briefly summarize the whole process in a sentence, highlighting the total number of steps involved, the starting point, and the endpoint.

   • Body Paragraphs (2-3 paragraphs): Describe the process sequentially, breaking it into logical sections.

   • Conclusion (1 sentence): Briefly summarize the overall process or its key characteristics.

3. Identify Transition Words: Plan to use suitable transition words to link steps (e.g., first, then, next, after that, subsequently, finally, in the next stage).

III. Writing Your Response (15-18 minutes)

1. Introduction: Start with a clear and concise introductory sentence. For example: "The diagram illustrates the process of making tea" or "The flowchart depicts the stages involved in the recycling of plastic."

2. Overview: Give a one-sentence overview that summarizes the main aspects of the process. For instance: "Overall, the process consists of five main stages, starting with the collection of raw materials and concluding with the packaging of the product."

3. Body Paragraphs:

   • Follow the Flow: Describe the steps in order. Start with the first step and proceed to the next logically, using transition words to connect each step.

   • Use Passive Voice: In process descriptions, the passive voice is common (e.g., "the sugar is heated", "the liquid is filtered"). This helps to emphasize the actions in the process rather than focusing on who or what is doing the action.

   • Specific Vocabulary: Use technical language if the process requires it. (e.g., evaporate, condense, extract, filter, distill, refine).

   • Avoid Over-Explanation: Don't give unnecessary details. Stick to describing the process stages accurately and concisely.

4. Conclusion: Sum up the overall process or the characteristics in one sentence. For example: "In conclusion, this is a sequential process, which begins with harvesting and ends with packaging the final product." or "In summary, the diagram illustrates a multi-stage process of extracting a raw material and making a usable product."

IV. Revision (2-3 minutes)

1. Check for the basics:

   • Make sure it is more than 150 words.

   • Make sure the overview is included.

   • Make sure that it follows a process.

2. Grammar: Review your response for errors in sentence structure, subject-verb agreement, and tense consistency.

3. Vocabulary: Ensure you have used specific and accurate vocabulary. Check for any misused words.

4. Cohesion: Check that your paragraphs and sentences are connected using appropriate transition words.

5. Task Completion: Ensure that your answer has addressed the task requirements. Make sure you have described all the main stages of the process.

Key Strategies & Tips

• Practice: Familiarize yourself with different types of process diagrams (e.g., natural cycles, manufacturing processes, cooking instructions).

• Vocabulary: Build a list of common process-related words and phrases.

• Sentence Variety: Use a mix of simple and complex sentences to improve your grammatical range.

• Time Management: Stick to the recommended times for planning, writing, and revising.

• Read Sample Answers: Analyze model responses to understand how to organize and structure your answer effectively.

Example Transition Words and Phrases:

• Starting: To begin with, first of all, initially, the first step is

• Continuing: then, next, after that, following this, subsequently, in the next stage

• Concluding: finally, lastly, in the end, the final step is

• General: after, before, during, while, as soon as, once

The diagram below shows the manufacturing process for making sugar from sugarcane.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.

Understanding the Task

• Task Type: Process Diagram

• Objective: Describe the stages involved in the sugar manufacturing process from sugarcane.

• Key Actions:

  • Summarize the main stages of the process.

  • Describe the progression logically, using transition words.

  • Use appropriate vocabulary for processes and equipment.

  • Write at least 150 words.

Key Elements to Focus On:

1. Beginning: Start with the growing stage and harvesting.

2. Extraction: Describe the crushing of sugarcane and the steps to purify the juice.

3. Transformation: Explain the evaporation of juice into syrup and the separation of sugar crystals.

4. Final stage: Describe the drying and cooling of sugar.

Model Answer (Band 9 Level)

The diagram illustrates the process of manufacturing sugar from sugarcane, beginning with cultivation and culminating in the final product. Overall, the process involves seven distinct stages of growing, harvesting, processing, and refinement.

The process commences with growing sugarcane, which takes between 12 and 18 months to mature. Subsequently, the sugarcane is harvested through manual labor and with the aid of machinery. The harvested sugarcanes then proceed to the next stage where they are crushed to extract the juice. Following this, the extracted juice is purified using a limestone filter.

After the purification, the juice is transferred to an evaporator where it is heated until it becomes syrup. The syrup is then processed through a centrifuge to separate the sugar crystals from the syrup. Lastly, these sugar crystals undergo a drying and cooling process, resulting in the final product.

In summary, the production of sugar from sugarcane is a multi-stage process, integrating agricultural practices with mechanical and chemical procedures.

   • Summarizes the key steps in one sentence.

3. Body Paragraph 1 (3 sentences):

   • Describes the first two stages: growing and harvesting with time and ways to harvest.

   • Uses the word "Subsequently" to indicate a transition to the next stage.

   • Describes the next stage with the word "then," then it uses the phrase "where they are crushed" to describe the place where crushing happens.

4. Body Paragraph 2 (3 sentences):

   • Describes the following stages (purifying, evaporation, separation).

   • Uses transition phrases, "Following this," "After the purification," and "Lastly" to indicate process.

   • Connects the separation of sugar with a new sentence: "these sugar crystals."

5. Conclusion (1 sentence):

   • Summarizes the process by highlighting the integration of practices and procedures with appropriate word choice.

   • Uses the word "multi-stage" to indicate it is not only one stage and uses "integrating" to say that the stages work together.
