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 making bamboo fabric, from planting bamboo plants to producing clothes.

Overall, there are nine stages in the process. It begins with the growing and harvesting ofbamboo and ends with weaving the fibres into fabric, which is then used to make clothing. The process involves several mechanical and chemical steps to transform the raw bamboo into usable textile material.

Firstly, bamboo plants are planted in spring and harvested in autumn. After harvesting, the bamboo is cut into strips. These strips are then crushed to produce liquid pulp. Next, the pulp is filtered to separate the long fibres from the liquid.

After that, the fibres are softened by adding water and ammonium oxide. The softened fibres are then spun to make yarn. In the following stages, the yarn is woven to produce bamboo fabric. This woven material forms the main textile that can be used in the clothing industry. Finally, the fabric is used to make clothes, such as t-shirts and socks.

AI examiner evaluation

Task Achievement / Task Response — Band 7.5

The student successfully addresses all parts of the task by providing a clear summary of the process of making bamboo fabric. The response accurately identifies the main stages, starting from planting and harvesting through mechanical and chemical processing, and ending with the production of clothes. An effective overview is provided in the second paragraph, outlining the total number of stages and the overall nature of the procedure. Key features such as cutting into strips, crushing into pulp, filtering, softening with water and amine oxide (noted as ammonium oxide by the student), spinning, and weaving are all reported accurately. The response meets all the requirements for a Band 7 or 8 level of task fulfillment in Task 1.

Coherence and Cohesion — Band 8.0

The response is logically organized with a clear progression from the beginning to the end of the manufacturing process. Cohesive devices are used effectively to guide the reader through the stages, using sequencing words such as 'Firstly', 'After harvesting', 'Next', 'After that', and 'Finally'. Paragraphing is used appropriately, with a clear introduction and overview followed by well-structured body paragraphs that detail specific segments of the flowchart. Referencing is clear and unambiguous throughout the text, resulting in a cohesive and easy-to-follow report.

Lexical Resource — Band 7.0

The student demonstrates a sufficient and generally appropriate range of vocabulary for this task type. Words and phrases such as 'manufacturing', 'liquid pulp', 'textile material', and 'softened fibres' are used accurately. There is a minor slip where 'amine oxide' from the diagram is written as 'ammonium oxide', but this does not impede communication. The writer attempts some less common lexical items with adequate control, though vocabulary could be slightly more varied in places to reach the highest bands.

Grammatical Range and Accuracy — Band 8.0

The text displays a good variety of sentence structures, including both simple and complex forms (e.g., 'It begins with the growing and harvesting of bamboo and ends with weaving the fibres into fabric, which is used to make clothing'). The passive voice is appropriately utilized for process description, as seen in 'bamboo plants are planted', 'the bamboo is cut into strips', and 'the pulp is filtered'. The majority of sentences are error-free, and grammatical control is strong throughout, with only a minor spacing typo ('harvesting ofbamboo').
