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 process diagram illustrates how fabric is manufactured from bamboo.

Overall, the process consists of nine main stages, beginning with bamboo being cultivated in spring and ending with the woven material being transformed into pieces of clothing. The process involves several mechanical and chemical steps, during which the bamboo gradually changes from a natural plant into usable textile material.

At the first stage, bamboo is cultivated in spring. Following this, the plants are harvested in autumn. Subsequently, the bamboo is cut into strips. These strips are then crushed to produce liquid pulp, which is filtered using a filtration device that separates the long fibres from the liquid.

After this stage, the softened fibres are mixed with water and amino oxide. The mixture is then spun to create yarn. The yarn is subsequently converted into woven material, which is used to make fabric. Afterwards, the material is processed to produce pieces of clothing.

AI examiner evaluation

Task Achievement / Task Response — Band 7.0

The response successfully covers all stages of the bamboo manufacturing process, from cultivation to the final product. You have provided a clear overview that identifies the main features, such as the transition from mechanical to chemical processing. The information is logically selected and presented in a clear sequence. To reach a higher band, you could improve the 'comparison' aspect by explicitly noting the shift from physical processing (crushing/cutting) to chemical processing (adding amino oxide), which would provide a more analytical summary of the diagram's structure rather than just a sequential list of steps.

Coherence and Cohesion — Band 8.0

The essay is well-organized with a clear introduction, overview, and body paragraphs. The progression of ideas is logical and easy to follow. You have used a good range of cohesive devices such as 'Following this', 'Subsequently', and 'Afterwards' to link the stages of the process. The paragraphing is appropriate, separating the initial stages from the later chemical and manufacturing phases. The flow is smooth, and the referencing is clear throughout the text, ensuring that the reader can easily track the transformation of the bamboo.

Lexical Resource — Band 7.0

You have used a sufficient range of vocabulary appropriate for a process description, such as 'cultivated', 'harvested', 'crushed', and 'filtered'. The terminology is accurate and fits the context of the diagram well. While the vocabulary is functional and precise, it lacks a few more sophisticated or 'less common' lexical items that would demonstrate a wider range. To improve, try to incorporate more varied verbs or nouns related to industrial processes, such as 'extracted', 'synthesized', or 'transformed into a viscous state'.

Grammatical Range and Accuracy — Band 7.5

The writing demonstrates a good command of grammatical structures with a mix of simple and complex sentences. Most sentences are error-free, and the punctuation is used correctly. You have effectively used passive voice constructions, which are essential for describing processes (e.g., 'bamboo is cultivated', 'strips are then crushed'). There are no significant errors that impede communication. To aim for a higher band, you could experiment with more complex sentence structures, such as using participle clauses or more varied subordinating conjunctions to link the stages even more fluidly.
