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 5.0)

the flow diagram illustrates how fabric is manufactured from bamboo. overall, bamboo undergoes through different stages to become fabric. first the bamboo springs are grown and pass through a number of stages until they reach the last stage where the strips are crushed to make pulp.

At first the bamboo plants are planted meanwhile they are harvested and after which they are cut into strips. lateron, the fibres are softened by adding water and amine oxide. eventually, the process of filtering is done to separate long fibres from liquid. lastly, strips are crushed to make liquid pulp.

Task Achievement / Task Response — Band 4.0

The response fails to meet the minimum word count requirement of 150 words, reaching only 97 words. This significantly impacts the ability to fully develop the response. While the overview is present, the description of the manufacturing process is incomplete and lacks the necessary detail to fully explain the stages shown in the diagram. The response misses key steps such as the chemical processing and the final production of the fabric, leading to an underdeveloped summary. To improve, you must ensure all stages of the process are described in detail and that the response meets the minimum length requirement to allow for full task completion.

Coherence and Cohesion — Band 5.0

The response is organized into two short paragraphs, which is insufficient for a clear, logical progression. While there is a basic attempt at sequencing using words like 'first', 'meanwhile', and 'eventually', the transitions feel mechanical and repetitive. The lack of sufficient content makes it difficult to establish a cohesive flow between the stages of the process. To improve, you should use a wider variety of cohesive devices to link ideas more naturally and ensure that each paragraph has a clear focus, such as separating the initial preparation stages from the chemical and final manufacturing stages.

Lexical Resource — Band 5.0

The vocabulary is limited and repetitive, relying on basic terms like 'stages', 'process', and 'make'. There is little attempt to use academic or process-specific vocabulary that would be expected in a task of this nature. For example, 'bamboo springs' is an inaccurate description of the raw material, and 'lateron' is informal and incorrectly spelled. To improve, you should incorporate more precise terminology related to manufacturing, such as 'raw material', 'chemical treatment', 'extraction', and 'conversion', while ensuring that your word choices are appropriate for a formal academic report.

Grammatical Range and Accuracy — Band 5.0

The response contains several grammatical errors and awkward phrasing. For instance, 'bamboo undergoes through different stages' is incorrect; it should simply be 'undergoes different stages'. There are also issues with punctuation and capitalization, such as starting sentences with lowercase letters and using 'lateron' as one word. The sentence structures are relatively simple, and there is a lack of complex grammatical forms. To improve, focus on using a wider variety of sentence structures, such as passive voice constructions which are essential for describing processes, and ensure that your basic grammar, punctuation, and spelling are accurate.
