IELTS Writing Task 1 question

The diagram below shows how fabric is manufactured from bamboo.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Write at least 150 words.

Student answer (Band 6.5)

The diagram illustrates the 9-stage process of manufacturing fabric from bamboo plants. Overall, it is a linear, seasonal process that moves from agriculture to textile production, with chemical and mechanical treatments in the middle stages.

The process begins with agriculture and harvesting. In *Step 1*, bamboo plants are planted in *Spring*. After a growing period, they are *harvested in Autumn* in Step 2. This shows a clear seasonal cycle before any manufacturing takes place.

Once harvested, the raw material goes through mechanical processing. In *Step 3*, the bamboo is *cut into strips*, and in *Step 4* these strips are *crushed to make liquid pulp*. Next, in *Step 5*, the mixture is *filtered* to separate the long fibres from the liquid.

The fibres then undergo chemical treatment and textile production. In *Step 6*, the fibres are *softened by adding water and amine oxide*. After that, they are *spun into yarn in Step 7*. The yarn is then *woven into fabric in Step 8*.

Finally, in *Step 9*, the finished bamboo fabric is used to make consumer products such as a t-shirt and socks.

In comparison to the first half, the first 4 steps focus on preparing raw bamboo material, while steps 5 to 8 focus on transforming that material into usable textile fibres and fabric. The final step shows the end application. The process combines natural growth cycles with both mechanical steps like cutting and crushing, and chemical steps like filtering and softening, to turn a plant into wearable fabric.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The response effectively covers all stages of the bamboo manufacturing process. You have successfully identified the main features, such as the seasonal nature of the harvest and the transition from mechanical to chemical processing. The overview is clear and provides a good summary of the entire cycle. You have also made relevant comparisons between the preparation phase and the transformation phase, which adds depth to your analysis. The information is well-selected and accurately reflects the provided diagram, meeting all requirements for a high-scoring response.

Coherence and Cohesion — Band 6.5

The response is logically organized, with a clear progression from the initial agricultural stages to the final product. Each paragraph has a distinct focus, which helps the reader follow the process easily. You have used cohesive devices effectively, such as 'Once harvested', 'Next', and 'In comparison to the first half', to link ideas smoothly. The paragraphing is appropriate and contributes to the overall clarity of the report. The flow of information is natural and consistent throughout the text.

Lexical Resource — Band 6.0

You have used a sufficient range of vocabulary to describe the process accurately. Terms such as 'linear', 'seasonal cycle', 'raw material', and 'consumer products' are used correctly and appropriately for this task. While the vocabulary is functional and precise, there is room to incorporate more sophisticated or technical collocations related to manufacturing processes to reach the highest band. However, the current range is more than adequate for the task, and there are no errors in word choice that impede communication.

Grammatical Range and Accuracy — Band 6.5

The writing demonstrates a good command of grammatical structures. You have used a mix of simple and complex sentences effectively, such as 'The process combines natural growth cycles with both mechanical steps... and chemical steps... to turn a plant into wearable fabric.' The punctuation is accurate, and the sentence construction is generally error-free. The majority of your sentences are clear and well-formed, showing good control over tense and subject-verb agreement. There are no significant grammatical errors that distract the reader.
