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 three main stages. Initially, bamboo is planted and harvested. It is then processed into fibres, which are eventually spun into yarn and woven to produce fabric. Finally, the finished fabric can be used to make different types of clothing.

In the first stage, bamboo is planted in spring and harvested in autumn. The harvested bamboo is then cut into thin strips. In the second stage, these strips are crushed to produce liquid pulp. After this, the long fibres are filtered from the liquid and then softened by adding water and amine oxide.

In the final stage, the softened fibres are spun to create yarn. The yarn is subsequently woven together to manufacture bamboo fabric, completing the main production process. At this point, the fabric can be transformed into different shapes and sizes and used to manufacture a variety of clothing items, such as shirts, socks and other garments.

Task Achievement / Task Response — Band 7.5

The response effectively covers all stages of the bamboo manufacturing process, from planting to the final production of garments. The overview clearly identifies that the process consists of three main stages, which helps the reader understand the logical flow. Key features, such as the crushing of strips into pulp and the chemical treatment with amine oxide, are accurately reported. The response is well-balanced, providing sufficient detail for each stage without becoming overly descriptive. It successfully highlights the transformation of raw material into a finished product, meeting the requirements of the task well.

Coherence and Cohesion — Band 7.5

The essay is logically organised, with a clear introduction, body paragraphs for each stage, and a concluding summary. The use of cohesive devices such as 'Initially', 'In the first stage', 'After this', and 'In the final stage' creates a smooth progression of information. Paragraphing is used effectively to separate the different phases of the manufacturing process. The referencing is clear, and the flow between sentences is natural, making the text easy to follow throughout.

Lexical Resource — Band 6.5

The vocabulary is accurate and appropriate for a process description. The student uses technical terms correctly, such as 'liquid pulp', 'filtered', 'softened', and 'amine oxide'. There is a sufficient range of vocabulary to describe the process with precision. While the range is adequate, it could be further enhanced by incorporating more sophisticated synonyms for common verbs like 'make' or 'create' to demonstrate a higher level of lexical flexibility.

Grammatical Range and Accuracy — Band 7.5

The response demonstrates a good command of grammatical structures. The use of passive voice is particularly appropriate for a process description, as seen in 'bamboo is planted', 'strips are crushed', and 'fibres are filtered'. The sentence structures are varied, combining simple and complex sentences effectively. Punctuation is accurate, and there are no significant errors that impede communication. The control over grammar is consistent, with most sentences being error-free.
