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 how bamboo fabric is made.

Overall, it is a process diagram and consists of nine processes. The steps started from planting, harvesting, cutting, crushing, filtering, softening, spinning and ended with weaving which produce the final product to the final consumer. It involves both mechanical and electrical energy.

First, bamboo plants are planted during spring and then harvested mechanically during autumn. Next, the plants are cut into strips and then transferred into a crusher to make liquid pulp. Following this, the liquid pup is then poured into a container to separate the long fibres from liquid using a filter.

At this stage, water and amine oxide are added to soften the fibres. After this, the fibres are spun to make yarn. Subsequently, the yarn are then weaved to make fabric. Finally, the fabric are designed to produce the final product such such clothes, socks. The final product is then used by the final consumer.

Task Achievement / Task Response — Band 6.5

The student successfully addresses all parts of the task by providing a clear overview and summarizing the main features of the bamboo fabric manufacturing process. The response identifies the key stages, starting from planting and harvesting through to crushing, filtering, softening, spinning, and weaving. Comparisons or sequential relationships are well reported, outlining mechanical and transformation steps. While some finer details from the diagram could have been expanded upon slightly more, the main trends and stages are adequately covered, fulfilling the requirements for a Band 6.5 or 7.0 descriptor. The selection of features is relevant and gives a clear picture of the overall linear process.

Coherence and Cohesion — Band 6.5

The text demonstrates a clear overall progression from the beginning to the end of the manufacturing process. The response is divided into logical paragraphs, separating the introduction, early stages, and later manufacturing steps. Cohesive devices such as 'First', 'Next', 'Following this', 'At this stage', and 'Finally' are used to sequence the information effectively, although some transitions feel a bit mechanical. Referencing is generally clear, for instance, linking the yarn to the weaving stage. Paragraphing is used sufficiently and appropriately, guiding the reader smoothly through the nine-step diagram, aligning well with the Band 6.5 to 7.0 criteria.

Lexical Resource — Band 6.0

The student uses an adequate range of vocabulary suitable for describing a technical process, including terms like 'crusher', 'liquid pulp', 'fibres', 'spinning', and 'weaving'. There are some successful attempts at less common lexical items, such as 'amine oxide' and 'mechanically'. However, there are noticeable spelling and word choice errors, including 'pup' instead of 'pulp' and repetitive phrasing like 'final product' and 'final consumer'. Furthermore, subject-verb agreement errors occur with vocabulary structures, such as 'the yarn are' and 'the fabric are'. Despite these inaccuracies, communication is not impeded, placing the response solidly in the Band 6.0 range.

Grammatical Range and Accuracy — Band 6.0

The response includes a mix of simple and complex sentence forms, demonstrating attempts at passive voice constructions, which are essential for process diagrams (e.g., 'bamboo fabric is made', 'plants are planted', 'are transferred'). However, grammatical errors are frequent enough to prevent a higher score. Examples of errors include subject-verb agreement issues ('the yarn are then weaved', 'the fabric are designed'), a spelling typo ('liquid pup'), and a redundant repetition ('such such clothes'). While the complex structures are generally understandable, the frequency of basic grammatical slips keeps the performance at a Band 6.0 level.
