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 presents the manufacturing process involved in the production of various clothes from bamboo plants.

From the broader overview, it is clear that the process involves both natural and industrial stages. In contrast, it starts with bamboo plantation and ends with the wearable clothes. The process consists of several stages such as harvesting, cutting, crushing, filtering, softening, making yarn and weaving.

The process begins with the bamboo plantation, which usually occurs in spring. Once the bamboo becomes mature in autumn, it is harvested. These harvested plants are further cut down into the fine strips. Additionally, these strips are crushed to make the liquid pulp. This liquid pulp undergoes filtration process to separate the long fibers from the liquid.

Moreover, these long fibers are softened by adding water and amine oxide. After the softening, these fibers are spin to make yarn. Once the yarn is created, weaving process is done to make fabric. By combining this fabric various types of wearable clothes are made, such as t-shirts, socks and so on.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The response successfully identifies the main stages of the bamboo manufacturing process. You have provided a clear overview and followed the sequence logically from harvesting to the final product. To reach a higher band, ensure you include more specific comparisons or highlight the transformation of the material more explicitly. For example, noting that the process is entirely linear and involves both mechanical and chemical treatments would add depth. The summary is accurate and covers all key steps shown in the diagram without omitting significant information, which demonstrates a good grasp of the task requirements.

Coherence and Cohesion — Band 6.5

The essay is logically organized into clear paragraphs, with each stage of the process following a chronological order. You use cohesive devices such as 'From the broader overview', 'Additionally', and 'Moreover' to link ideas effectively. However, some transitions feel slightly mechanical. To improve, try to vary your linking phrases and ensure that the progression between sentences is smoother. The paragraphing is appropriate, separating the introduction/overview from the detailed process steps, which helps the reader follow the information easily. Overall, the flow is logical and easy to follow throughout the response.

Lexical Resource — Band 6.0

You demonstrate an adequate range of vocabulary for the task, using terms like 'plantation', 'mature', 'filtration', and 'amine oxide' correctly. While the vocabulary is sufficient to convey the process clearly, it lacks the sophistication required for a higher band. There are some minor issues with word choice, such as 'these fibers are spin', which should be 'spun'. Expanding your range to include more precise process-related verbs and collocations would enhance the quality of your writing. The current vocabulary is functional and allows for clear communication of the technical steps involved.

Grammatical Range and Accuracy — Band 6.0

The response uses a mix of simple and complex sentence structures. While most sentences are clear, there are occasional grammatical errors, such as 'these fibers are spin' (should be 'spun') and 'weaving process is done' (missing an article, 'the weaving process'). Additionally, 'By combining this fabric various types of wearable clothes are made' is slightly awkward in phrasing. Despite these errors, the meaning is never obscured, and the grammar is generally reliable. To improve, focus on subject-verb agreement and the correct use of articles when describing technical processes.
