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 7.0)

The process chart illustrates the information regarding the production of fabric from bamboo.

By taking a general overview, it is seen that there are various steps performed in production of fabric from bamboo in which it starts with the plantation of bamboo whereas ends with manufacturing of clothes.

On analysing the process chart, it is observed that In the initial stages, bamboo plants are sown in spring and then harvested in autumn once they have matured. After harvesting, the stalks are mechanically cut into strips, which are subsequently crushed to form a liquid pulp, marking the end of the preparatory phase.

In the next sequence, the liquid pulp is filtered to separate the long fibres from the rest of the material. These extracted fibres are then softened using water and amine oxide, a chemical agent. Once softened, the material is spun into yarn, after which it is woven to produce fabric. Finally, the fabric is turned into garments, such as socks and T-shirts, completing the production cycle.

Task Achievement / Task Response: Band 7.0

The response covers the process from planting bamboo in spring through to finished clothing, and its overview correctly identifies the beginning and end points. It also reports the main transformations accurately: cutting and crushing the stalks, filtering and softening the fibres, then spinning and weaving. The specific mention of water and amine oxide, and the examples of socks and T-shirts, are grounded in the diagram. This gives the account clear coverage and relevant detail. To make the description more fully developed, clarify that the diagram presents a sequence of nine stages and distinguish the conversion of pulp into fibres from the later yarn-making and fabric-making stages. The phrase “production cycle” is slightly imprecise because the process is shown as linear rather than cyclical.

Coherence and Cohesion: Band 7.0

The information is arranged in a clear progression, with an overview followed by two paragraphs that move from cultivation and preparation to fibre processing and the final products. Sequencing expressions such as “After harvesting,” “In the next sequence,” “Once softened,” and “Finally” help the reader follow the stages. Paragraphing is appropriate and the references to “these extracted fibres” and “the material” generally connect ideas effectively. Some linking is a little formulaic, particularly the repeated stage-introducing phrases, and “marking the end of the preparatory phase” creates a division that is not explicitly indicated in the diagram. A more concise transition and clearer grouping of the nine stages would make the progression feel more natural and cohesive.

Lexical Resource: Band 6.5

The response uses a suitable range of process vocabulary, including “harvested,” “crushed,” “filtered,” “softened,” “spun,” and “woven,” and these terms communicate the manufacturing stages clearly. It also includes relevant technical detail such as “liquid pulp” and “amine oxide.” However, some choices are awkward or imprecise: “By taking a general overview” is not a natural way to introduce an overview, while “plantation of bamboo” and “production cycle” are less suitable for this context. “Chemical agent” adds an interpretation that the diagram does not provide. These occasional collocational and word-choice issues do not obscure the meaning, but more natural, precise phrasing would improve flexibility and control.

Grammatical Range and Accuracy: Band 6.5

There is a useful mix of sentence forms, including complex clauses such as “After harvesting, the stalks are mechanically cut into strips, which are subsequently crushed…” and the passive constructions appropriate for describing a process. Most stages are expressed clearly, and the use of present simple and passive forms is generally controlled. Some grammatical awkwardness remains: “in production of fabric” is missing an article, and “it starts with the plantation … whereas ends with manufacturing” has an unclear subject and an incomplete parallel structure. The capital letter in “In” after “that” is also incorrect. These are limited issues rather than barriers to understanding; more consistent article use and parallel phrasing would strengthen accuracy.
