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 process diagram illustrates the production of fabric from bamboo plants.

Overall, it can be seen that the plantation of bamboo plants during Spring, followed by its harvestation in Autumn, which further undergoes several mechanical and chemical processes from cutting sticks into long fibres to soften it, resulting in the production of yarn, which is then used to make fabrics.

At the beginning, the bamboo plants are planted in Spring and harvested during Autumn. The stem is then cut into long strips followed by its crushing to form liquid pulp. The pulp then passes through a filtration process which is used to separate long strips from the liquid. The subsequent addition of water and amine oxide softens the fibre.

At step 7, the fibres are then spun resulting in the formation of yarn, which is then weaved to make fabric. This fabric is further converted into different types of goods including shirts and socks.

AI examiner evaluation

Task Achievement / Task Response — Band 7.0

The student successfully addresses all parts of the task by outlining the entire process of manufacturing fabric from bamboo. The overview paragraph captures the main stages effectively, moving from the initial planting and harvesting in Spring and Autumn, through mechanical and chemical preparation, to the final spinning, weaving, and production of goods. Key features such as crushing, filtering, and softening with water and amine oxide are accurately reported. The information is well-selected and directly grounded in the visual data without significant omissions.

Coherence and Cohesion — Band 6.5

The response is logically organized with a clear overall progression from the beginning to the end of the manufacturing process. Paragraphing is used appropriately to separate the introduction, the overview, the middle chemical/mechanical steps, and the final stages. Cohesive devices are employed reasonably well to guide the reader through the sequence, such as 'At the beginning', 'The pulp then', and 'At step 7'. However, some transitions feel slightly mechanical, and referencing could be smoother in places, which prevents a higher band score.

Lexical Resource — Band 6.0

The student demonstrates an adequate and generally appropriate range of vocabulary for the task, successfully utilizing process-related terms such as 'filtration process', 'liquid pulp', and 'amine oxide'. There are some awkward lexical choices or word forms, such as 'plantation of bamboo plants' instead of 'planting of bamboo', and 'harvestation' instead of 'harvesting'. Despite these occasional inaccuracies and word-choice errors, communication is never impeded, and the vocabulary remains functional.

Grammatical Range and Accuracy — Band 6.0

The response exhibits a mix of simple and complex sentence structures, including participial phrases and relative clauses. There are some control issues with grammar, particularly in the lengthy overview sentence which becomes slightly tangled ('followed by its harvestation in Autumn, which further undergoes...'). Minor agreement and pronoun reference errors also occur ('followed by its crushing', 'to soften it'). Nonetheless, many sentences are accurate, and punctuation is handled well enough that the meaning remains clear throughout.
