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 illustrates the sequential multi-stage process by which textile fabric is manufactured from raw bamboo plants.

Overall, the production cycle spans a combination of agricultural cultivation and mechanical processing. The journey begins with the seasonal growing and harvesting of the crop, followed by physical processing and refinement to extract the long fibers required for weaving cloth.

In the initial agricultural stages, bamboo stalks are planted during the spring season. After growing throughout the summer months, the mature bamboo is harvested in the autumn. Once harvested, the raw stalks undergo immediate physical modification by being processed through a mechanical saw to be cut into thin strips.

The subsequent refining phases focus on transforming the solid wood into pliable textile material. First, the bamboo strips are mechanically crushed down until they form a dense liquid pulp. Following this, a filtration step is carried out to carefully separate the valuable long fibers from the surrounding liquid waste. Finally, these isolated fibers undergo a softening phase, where water and chemical agents are introduced to prepare the raw fibers for eventual spinning into woven fabric.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

The student provides a clear overview of the process and reports the main features accurately. The response outlines the steps from planting and harvesting to physical processing and chemical treatment. However, the summary is incomplete because it omits the final stages of the process, specifically spinning the yarn and weaving the fabric into final items. While the introduction and the first four steps of the manufacturing cycle are described in detail, stopping short of the final product prevents the response from fully covering all parts of the visual data. This leads to an under-development of the final sequence, capping the task achievement score.

Coherence and Cohesion: Band 7.0

The text demonstrates a clear logical progression and overall cohesion. The response is divided into logical paragraphs separating the introduction, overview, agricultural stage, and processing stages. Cohesive devices are used effectively to guide the reader through the sequence, as seen with transition phrases like 'Once harvested', 'First', 'Following this', and 'Finally'. Paragraphing is handled appropriately, ensuring that each stage of the linear process receives its own structured focus. Referencing is clear throughout, making the text easy to follow despite the omission of the final diagram steps.

Lexical Resource: Band 6.5

The vocabulary used is generally adequate and appropriate for an academic task describing a manufacturing process. The student successfully employs terms such as 'sequential multi-stage process', 'agricultural cultivation', 'physical modification', and 'filtration step'. There are attempts to use less common lexical items like 'pliable', 'refining phases', and 'chemical agents'. Minor awkwardness appears in word choice, such as referring to bamboo stalks as 'solid wood', but these do not impede communication. The range of vocabulary is sufficient to convey the process clearly.

Grammatical Range and Accuracy: Band 7.0

The student exhibits good control over a mix of simple and complex sentence structures. Complex structures are handled reasonably well, demonstrated by sentences such as 'Once harvested, the raw stalks undergo immediate physical modification by being processed through a mechanical saw to be cut into thin strips.' There are minor grammatical slips, such as the slightly clumsy phrasing in 'spans a combination of agricultural cultivation and mechanical processing', but the majority of sentences are grammatically sound. Punctuation is accurate, and errors do not interfere with the readability of the text.
