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 5.5)
The given chart illustrates the process of manufacturing the fabric from bamboo.
Overall, it is apparent that the making of various new products is natural and it is evident that it has nine stages.
To begin with, it is apparent that plantation of bamboo is done in spring season and they are harvested in the Autumn. Afterwards, the bamboos are cut into fine strips by a blade. To enable further processing, the strips are crushed into liquid pulp, but it still has some impurities in it, for that a filter is used to separate long fibres present in liquid. Now, the pure liquid is mixed with water and a chemical known as amine oxide to soften the fibres.
The next stage involves spinning which is used for making yarn balls to make fabric by weaving it and giving it shape. Finally, the end products like t-shirts and socks are ready to sell.

Task Achievement / Task Response — Band 5.5
The response covers the main stages of the bamboo manufacturing process, from plantation to end products. However, the overview is somewhat weak; stating that the process is 'natural' is a subjective observation rather than a summary of the key features of the process itself. While the response identifies the nine stages, it lacks a clear comparison or a more analytical summary of the transformation from raw material to finished goods. The description of the stages is accurate, but the response would benefit from a more professional tone and a more detailed overview that highlights the transition from raw bamboo to chemical-treated pulp.
Coherence and Cohesion — Band 6.0
The response is logically organized, following the chronological order of the diagram. Paragraphing is used to separate the initial stages from the final processing stages. Cohesive devices such as 'To begin with', 'Afterwards', and 'Finally' are used to guide the reader through the process. However, some transitions feel slightly mechanical, and the flow between sentences could be improved by using more varied linking phrases. The overall structure is clear and easy to follow, meeting the requirements for a coherent response.
Lexical Resource — Band 5.5
The vocabulary is generally adequate for the task, with terms like 'plantation', 'harvested', 'liquid pulp', and 'amine oxide' used correctly. However, the range is somewhat limited, and there is a reliance on basic phrasing such as 'making of various new products' and 'ready to sell'. To achieve a higher band, the student should incorporate more precise technical vocabulary related to industrial processes, such as 'extraction', 'conversion', or 'synthetic'. There are no significant spelling errors, and the word choice is sufficient to convey the intended meaning clearly.
Grammatical Range and Accuracy — Band 5.5
The response uses a mix of simple and complex sentence structures. There are some grammatical inaccuracies, such as 'plantation of bamboo is done in spring season' (missing articles) and 'for that a filter is used' (awkward phrasing). While these errors do not impede communication, they indicate a lack of full control over complex structures. The use of passive voice is appropriate for a process description, but the sentence variety could be improved to demonstrate greater grammatical flexibility. Punctuation is generally accurate throughout the text.
