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, from the initial cultivation of the plants to the production of finished clothing.

Overall, there are nine main stages in the process. It begins with planting bamboo in spring and harvesting it in autumn, while the remaining stages involve mechanically processing the bamboo into fibres, which are eventually spun, woven and made into clothing.

Initially, bamboo plants are grown in spring and are harvested in autumn when they are mature. The harvested bamboo is then cut into thin strips, which are subsequently crushed to produce a liquid pulp. Next, this pulp is passed through a filter to separate the long fibres from the liquid.

Following this, the extracted fibres are softened by adding water and amine oxide. Once the fibres have been softened, they are spun to create yarn. The yarn is then woven together to produce bamboo fabric. In the final stage, this fabric is used to manufacture various textile products, such as T-shirts and socks.

Thus, the process involves a combination of agricultural, mechanical and textile-processing stages, transforming raw bamboo plants into usable fabric and finished garments.

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 overview of the entire bamboo fabric manufacturing process, as seen in "there are nine main stages in the process." Key features and sequential steps—from planting in spring and harvesting in autumn to the final production of garments like T-shirts and socks—are accurately reported without any noticeable omissions or misinterpretations of the visual data. The progression is logical and well-grounded in the provided diagram, fulfilling all requirements of Band 8.

Coherence and Cohesion: Band 7.5

The response exhibits a clear logical organisation and progression throughout. Information is grouped coherently into four well-structured paragraphs that separate the introduction, overall summary, and successive stages of the process. Cohesive devices such as "Overall," "Initially," "Following this," and "In the final stage" are used naturally and effectively to guide the reader through the linear and cyclical phases of the diagram. Referencing is consistently clear, ensuring seamless transitions between sentences and paragraphs, which aligns comfortably with the descriptors for a Band 8.

Lexical Resource: Band 6.5

The student demonstrates a sufficient and appropriate range of vocabulary for the task, successfully employing less common items and process-specific terminology such as "cultivation," "mechanically processing," "liquid pulp," "amine oxide," and "textile products." Word choices and collocations are generally accurate and natural, as seen in "extracted fibres" and "finished garments." While the range is competent and meets the criteria for Band 7, it falls slightly short of the flexible and highly sophisticated range required for a higher band.

Grammatical Range and Accuracy: Band 7.5

The writing features a good variety of complex structures alongside simple sentences, demonstrating sound grammatical control. Examples include participial and adverbial clauses such as "from the initial cultivation... to the production" and "Once the fibres have been softened, they are spun..." The majority of sentences are completely error-free, with accurate punctuation and tense consistency throughout the description of the manufacturing process. This level of accuracy and structural variety comfortably supports a Band 8 score.
