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 provides a visual summary of the process of designing clothes from fabric that is processed from a bamboo plant.

Bamboo is used as the raw material for manufacturing the fabric. It is best sown in the months of spring so that the same can be harvested during autumn. Bamboo requires preprocessing before the end product is obtained and this can be largely divided into 6 different steps .

Once bamboo is harvested, it is cut into strips using a mechanical chopper The cut strips are then crushed together to obtain liquid bamboo pulp. This pulp is a mixture of liquid along with the fibers that would eventually make up the yarn. Segregation of the long fibers from the liquid content is obtained by passing the pulp through a funnel shaped filter. To further soften the filtered long fibers, water along with a chemical called amine oxide is used in combination.

The softened fibers are spun to obtain balls of yarn which are then woven to produce fabric. Different types of clothes such as t-shirts and socks can then be made out of this pre made fabric.

AI examiner evaluation

Task Achievement / Task Response — Band 6.0

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. However, the task requires reporting on the 'main features' and making 'comparisons where relevant'. The response is purely descriptive and lacks a clear summary of the most significant stages or any comparative analysis of the transformation process. To reach a higher band, ensure you highlight the key stages more effectively and provide a more comprehensive overview in the introduction or summary paragraph.

Coherence and Cohesion — Band 6.5

The essay is logically organized, with a clear progression from the raw material stage to the final product. Paragraphing is used appropriately to separate the different phases of the process. Cohesive devices such as 'Once', 'The cut strips are then', and 'To further soften' are used effectively to guide the reader. However, some transitions feel slightly mechanical, and the connection between the harvesting phase and the processing phase could be smoother. Overall, the information is easy to follow, and the structure supports the clear communication of the process.

Lexical Resource — Band 6.5

You have used a range of vocabulary appropriate for a process description, such as 'preprocessing', 'mechanical chopper', 'segregation', and 'amine oxide'. These terms are used accurately and demonstrate a good grasp of the subject matter. There are no significant spelling errors, and the word choice is generally precise. To improve, try to incorporate more sophisticated collocations or varied synonyms to describe the transformation stages, as some phrasing remains quite simple, such as 'made out of this'.

Grammatical Range and Accuracy — Band 6.5

The response displays a good mix of simple and complex sentence structures. You have used passive voice effectively, which is essential for process descriptions (e.g., 'is used', 'are then woven'). While the grammar is generally accurate, there are minor punctuation errors, such as the missing period after 'mechanical chopper'. Additionally, some sentences could be more varied in their construction to demonstrate greater flexibility. Despite these minor issues, the grammar does not impede communication and shows a solid level of control.
