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.

Overall, the process consists of several stages, beginning with the cultivation and harvesting of bamboo and ending with the production of fabric, which is then used to make clothing. The process involves both mechanical and chemical treatment of the bamboo before it is converted into fabric.

Initially, bamboo is cultivated during spring and harvested in autumn once it has grown sufficiently. The harvested bamboo is then cut into narrow strips, which are subsequently crushed to produce liquid pulp. After this, the pulp is filtered in order to separate the long fibres from the liquid. The fibres are then treated with a mixture of water and amine oxide to make them softer.

In the next stage, the softened fibres are spun to produce yarn. This yarn is then woven to create fabric. In the final stage, the finished fabric is used to manufacture clothing items, including T-shirts and socks.

Overall, the process transforms bamboo from a raw plant material into finished fabric through a series of mechanical and chemical stages.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The student has successfully addressed all parts of the task by providing a clear and comprehensive summary of the process of manufacturing fabric from bamboo. The main features, such as the initial cultivation, mechanical and chemical treatments, and final production of clothing, are accurately reported. The overview presented in both the introduction and conclusion effectively captures the essence of the process without lifting whole phrases blindly from the prompt. There are no omissions of key stages shown in the diagram, and the information is fully grounded in the provided visual data, demonstrating a strong understanding of process diagrams.

Coherence and Cohesion — Band 7.5

The response is logically organized with a clear progression from the beginning to the end of the manufacturing process. Paragraphing is used effectively to group related steps, separating the introduction, the preliminary and chemical stages, the spinning and weaving stages, and the final conclusion. Cohesive devices such as 'Initially', 'After this', 'In the next stage', and 'In the final stage' are employed naturally to guide the reader smoothly through the sequence of events. Referencing is clear throughout, contributing to a seamless and coherent text.

Lexical Resource — Band 7.0

The student demonstrates a sufficient and appropriate range of vocabulary for an Academic Task 1 response. Less common lexical items related to manufacturing processes and chemistry are used effectively, including 'cultivation', 'mechanical and chemical treatment', 'liquid pulp', 'amine oxide', and 'spun yarn'. Word choices and collocations are generally accurate and natural, such as 'woven to create fabric' and 'finished fabric is used to manufacture clothing'. There are no noticeable spelling or word-choice errors that impede communication.

Grammatical Range and Accuracy — Band 7.5

The response features a good variety of complex sentence structures used accurately to describe sequential processes, such as 'Once it has grown sufficiently' and 'Which are subsequently crushed to produce liquid pulp.' The majority of sentences are error-free, and control over tense, voice (passive structures like 'bamboo is cultivated' and 'fibres are then treated'), and punctuation is strong. Grammatical control remains consistent throughout the text, allowing for smooth and precise communication without any noticeable interference from errors.
