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 diagram illustrates how fabric is produced from bamboo.

Overall, the process is composed of nine stages, beginning with the planting of bamboo plants during spring and ending with the manufactured clothing like t-shirt and socks. The bamboo plants also undergo both physical and chemical procedures before they turned into fabric that will eventually become an apparel.

First, the bamboo plants are planted during Spring and when they matured, they are harvested usually during Autumn. Afterwards, the bamboos are cut into smaller pieces called strips using a cutting machine. These strips are then crushed to make liquid pulp. Subsequently, the liquid pulp is filtered to separate the long fibers from the liquid. The fibers are then softened by adding water and amino oxide. Once completed, the fibers are spun to make yarn and are woven to make the fabric. Finally, the fabric is turned into clothing like t-shirt and socks.

AI examiner evaluation

Task Achievement / Task Response — Band 6.5

The response successfully covers all stages of the bamboo manufacturing process, from planting to the final product. The overview provides a clear summary of the nine-stage process and correctly identifies the nature of the procedures involved (physical and chemical). The main features are highlighted, and the progression is logical. To reach a higher band, the response could benefit from more explicit comparisons or a more detailed description of the chemical/physical transformation stages, such as mentioning the specific role of the solvent or the transition from liquid to solid fiber, which would demonstrate a deeper engagement with the visual data.

Coherence and Cohesion — Band 6.5

The response is well-organized with a clear introduction, an overview, and a body paragraph detailing the process. The use of cohesive devices such as 'First', 'Afterwards', 'Subsequently', and 'Finally' creates a logical flow that is easy to follow. Paragraphing is used appropriately to separate the summary from the detailed description. The progression of ideas is consistent throughout the text. To improve, the writer could vary the cohesive devices further to avoid a slightly mechanical feel, as the current structure relies heavily on simple sequential markers.

Lexical Resource — Band 6.5

The vocabulary is generally appropriate for the task, using terms like 'matured', 'harvested', 'filtered', and 'amino oxide' correctly. The range is sufficient to describe the process clearly. However, there are some minor inaccuracies and repetitive phrasing, such as 'manufactured clothing like t-shirt and socks' (should be plural 't-shirts') and 'turned into fabric that will eventually become an apparel' (apparel is an uncountable noun in this context). Expanding the range of verbs and nouns related to industrial processes would help elevate the score.

Grammatical Range and Accuracy — Band 6.5

The response demonstrates a mix of simple and complex sentence structures. There are some grammatical errors, such as 'before they turned into fabric' (should be 'turn') and 'like t-shirt and socks' (should be 't-shirts'). Additionally, 'the bamboos are cut' is slightly unnatural; 'bamboo' is typically uncountable in this context. While these errors do not impede communication, they indicate a need for more consistent control over tense consistency and pluralization. The use of passive voice is appropriate for a process description, which is a positive feature.
