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 5.5)

The flowchart illustrates the production process of textile material from bamboo tree.

Overall, process makes textile fabric from the bamboo tree. Fabric is made through several stages. Each operation derives their own principal. So, process starting from planting bamboo and at the end of the process, clothes are made by weaving.

Firstly, planting bamboo and give nutrients for their growth. Bamboo takes several years for maturing. Once bamboo have matured, harvest it and trim into narrow strips using machine. Afterwards grind the strips and produce liquid soft pulp. Fibers are separated from the pulp using chemical and mechanical methods like filtering.

Subsequently, water and amine oxide are added to soften the fibres. The fibres are spin into yarn. Make fabric sheets or weave from the yarn. Fabric is dyed, washed and treat with chemicals to enhance its quality. That textile material used to manufacture clothes, towels, bedsheets and textile products.

Task Achievement / Task Response — Band 5.5

The response covers the main stages of the bamboo manufacturing process, from planting to the final product. However, the overview is somewhat repetitive and lacks a clear summary of the key trends or the cyclical nature of the process. While the main features are identified, the description of the chemical and mechanical stages is a bit simplistic. To reach a higher band, you should aim to synthesize the information more effectively rather than simply listing the steps. The inclusion of specific details, such as the use of amine oxide, is good, but the overall development of the process flow could be more cohesive.

Coherence and Cohesion — Band 5.5

The response is organized into paragraphs, which helps the reader follow the process. However, the use of cohesive devices is somewhat mechanical and repetitive (e.g., 'Firstly', 'Afterwards', 'Subsequently'). Some transitions feel forced, and the logical flow between sentences could be improved. For instance, the second paragraph contains several short, choppy sentences that hinder the overall flow. Improving the variety of linking words and using more complex sentence structures to connect related ideas would significantly enhance the coherence of your writing.

Lexical Resource — Band 5.5

You demonstrate an adequate range of vocabulary for the task, using terms like 'nutrients', 'maturing', 'amine oxide', and 'textile material'. However, there are instances of awkward word choice and minor errors, such as 'derive their own principal' (likely meant 'principle') and 'treat with chemicals' (should be 'treated'). The vocabulary is generally functional but lacks the precision and sophistication required for higher bands. To improve, focus on using more precise collocations and ensuring that word forms are used correctly in context.

Grammatical Range and Accuracy — Band 5.0

The response contains a mix of simple and some complex sentence structures, but there are frequent grammatical errors. Examples include 'process starting from planting' (should be 'the process starts'), 'Once bamboo have matured' (subject-verb agreement error), and 'The fibres are spin into yarn' (incorrect verb form; should be 'spun'). These errors are noticeable but do not generally impede communication. To achieve a higher score, you need to demonstrate better control over verb tenses, subject-verb agreement, and passive voice constructions, which are essential for describing processes.
