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 6.5)

The given diagram shows the process of manufacturing bamboo fabric from bamboo plants in a step by step manner. It gives a broad overview of the various manufacturing steps involved in the production of the fabric.

In the springtime, bamboo plants are planted. They are allowed to grow into the autumn season, at which point they are harvested from the fields. These harvested bamboo shoots are then cut into strips using a circular saw. These strips are then crushed to make liquid pulp. The long fibres are required to be separated from the liquid, hence, the obtained liquid pulp is filtered. The obtained fibres are next softened. Softening is done by adding water and amine oxide.

These fibres are now soft enough to be spun to make yarn. Finally, this yarn can now be weaved to make bamboo fabric. This fabric can then be used to make whatever article of clothing is required.

AI examiner evaluation

Task Achievement / Task Response — Band 6.0

The response covers all stages of the bamboo manufacturing process, from planting to the final product. However, it lacks a clear 'overview' paragraph that highlights the most significant features or trends, such as the transition from biological growth to chemical processing. While the steps are described, the response would benefit from a more analytical approach rather than a purely sequential list. The summary is accurate, but it misses the opportunity to group the stages into distinct phases (e.g., cultivation, mechanical processing, and chemical treatment), which would demonstrate a higher level of task achievement.

Coherence and Cohesion — Band 6.5

The response is logically organized, following the chronological order of the diagram. Paragraphing is used to separate the growth phase from the manufacturing phase, which aids readability. Cohesive devices such as 'These strips are then', 'hence', and 'Finally' are used to link ideas. However, the flow is somewhat mechanical, relying heavily on simple sequential transitions. To reach a higher band, the student should aim for more varied cohesive links and ensure that the relationship between the stages is more explicitly stated rather than just listing them one after another.

Lexical Resource — Band 6.0

The vocabulary is generally appropriate for the task, with terms like 'liquid pulp', 'amine oxide', and 'harvested' used correctly. However, the range is somewhat limited and repetitive. Phrases like 'obtained liquid pulp' and 'obtained fibres' are used in close proximity, which reduces the sophistication of the writing. To improve, the student should incorporate more precise synonyms and avoid repeating the same descriptors. The use of 'whatever article of clothing is required' is slightly informal and imprecise for an academic report.

Grammatical Range and Accuracy — Band 6.5

The response demonstrates a mix of simple and complex sentence structures. There is good control over passive voice constructions, which is appropriate for describing a process (e.g., 'bamboo plants are planted', 'are then cut'). While there are few grammatical errors, the sentence structures are somewhat predictable. The punctuation is generally accurate, and the meaning is always clear. To achieve a higher score, the student should attempt more varied complex structures, such as using participle clauses or relative clauses to combine ideas more fluidly.
