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 6.0)

The provided flowchart illustrates the multi-stage process of producing textile-material from bamboo.

Overall, the transformation involves nine distinct steps, from the biological growth and harvest to textile manufacturing stage.

The cycle begins in the spring when the bamboo plants are planted, the stalks are harvested during autumn season. The raw bamboo enters on a physical transformation phase where specialized equipment is used to cut the stalks. These strips are subsequently crushed to make it a liquid pulp.

In the fifth stage, the pulp used filter to separate long fibers from liquid. In the next step, they undergo softening process in which the fibers are added by water and amine oxide to become a soft material. Once it becomes soften, it will spun to make a yarn. In the final stage, it involves weaving the yarn into fabric. The finalized fabric are clothes and socks, which are then ready for consumer use.

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 of the flowchart logically. However, the response is quite brief, and some stages could be described with more detail to better highlight the 'main features' and 'comparisons' required for a higher band. For instance, the transition from raw bamboo to liquid pulp is mentioned, but the specific chemical or mechanical processes could be elaborated upon further. You have addressed all parts of the task, but the development of ideas is somewhat limited, keeping this in the Band 6 range.

Coherence and Cohesion — Band 6.0

The response is logically organized, moving step-by-step through the process. You use some cohesive devices such as 'In the fifth stage', 'In the next step', and 'In the final stage' to guide the reader. However, the paragraphing is insufficient; the entire response is written as one block of text. For a process description, it is better to group stages logically into two or three paragraphs to improve readability. Additionally, some transitions feel a bit mechanical. Improving the variety of linking words and using paragraph breaks would significantly enhance the flow and coherence of your writing.

Lexical Resource — Band 6.0

You have used some appropriate technical vocabulary related to the process, such as 'liquid pulp', 'amine oxide', and 'textile-material'. However, there are some inaccuracies in word choice and collocation. For example, 'physical transformation phase' is slightly awkward, and 'the pulp used filter' is grammatically incorrect. You also use 'soften' as a verb incorrectly in 'Once it becomes soften'. While the vocabulary is adequate to convey the meaning, it lacks the precision and flexibility required for a higher band. Focusing on correct word forms and more natural collocations will help improve this score.

Grammatical Range and Accuracy — Band 5.5

The response contains a mix of simple and complex sentence structures. There are several grammatical errors that hinder the accuracy of the text, such as 'the pulp used filter' (should be 'the pulp is filtered') and 'the finalized fabric are clothes' (subject-verb agreement error). Additionally, 'the fibers are added by water' is an incorrect use of the passive voice; it should be 'water and amine oxide are added to the fibers'. While these errors do not completely impede communication, they are frequent enough to prevent a higher score. Focusing on subject-verb agreement and correct passive voice construction is essential.
