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 7.5)

The diagram illustrates the process of manufacturing fabric from bamboo, which consists of nine stages, beginning with the planting of bamboo and ending with the production of finished clothing.

Overall, the process is linear, with no repeated stages. It starts with the cultivation and harvesting of bamboo, which are dependent on the seasons, while the remaining stages mainly involve industrial processes such as cutting, crushing, filtering, spinning and weaving. The final product is bamboo fabric, which can be used to make items such as T-shirts and socks.

In the initial stage, bamboo plants are sown in spring and then harvested in autumn once they have matured. After harvesting, the bamboo stalks are manually cut into strips, which are subsequently crushed to produce a liquid pulp. In the next stage, the pulp is filtered to separate the long fibres from the liquid. These fibres are then softened by adding water and amine oxide. Once softened, the fibres are spun into yarn.

In the final stages, the yarn is woven to produce fabric. The finished fabric is then used to manufacture various clothing items, such as T-shirts and socks. Thus, the process transforms bamboo plants into usable fabric through a series of agricultural and industrial stages.

AI examiner evaluation

Task Achievement / Task Response: Band 7.5

The student successfully addresses all parts of the task by providing a clear and comprehensive summary of the nine-stage process of manufacturing bamboo fabric. The response accurately identifies the main features, such as the seasonal dependence of the early agricultural stages, the intermediate chemical and mechanical processes, and the final production of clothing items. The overview is well-crafted, capturing the linear nature of the workflow and the transition from raw material to finished goods. No important steps from the visual data are omitted or misread, demonstrating a thorough understanding of the diagram.

Coherence and Cohesion: Band 7.5

Information and ideas are logically sequenced and flow smoothly throughout the response. The text is divided into appropriate paragraphs that logically separate the introduction, overview, middle stages, and final steps. Cohesive devices are used effectively and naturally, such as 'Overall', 'In the initial stage', 'After harvesting', and 'In the final stages'. Paragraphing is skilful and contributes to a clear, coherent progression of information, ensuring the reader can easily follow the sequence of the manufacturing process.

Lexical Resource: Band 7.5

The student demonstrates a wide and appropriate range of vocabulary suitable for describing a technical process. Less common items such as 'cultivation', 'matured', 'subsequently', 'pulverized' (or 'liquid pulp'), and 'manually' are used accurately. Word choice and collocations are generally precise, reflecting a natural control of language. There are no noticeable spelling or word-choice errors, and the terminology directly matches the demands of Task 1 process descriptions.

Grammatical Range and Accuracy: Band 8.0

The response exhibits a wide range of complex grammatical structures used with a high degree of accuracy. The majority of sentences are error-free, featuring effective use of participial phrases ('beginning with the planting...', 'once they have matured') and passive constructions ('are sown', 'are then harvested', 'are spun into yarn'). Control over punctuation and sentence boundaries is strong, and any minor slips are entirely absent, allowing for smooth, uninterrupted reading.
