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 the sequential steps of manufacturing fabric from the raw material bamboo.

The total procedure takes about 9 steps from planting the bamboo plants in spring to making different types of garments with the finished fabric. This requires human labour, mechanical instruments and a variety of technical skills.

The first step is to plant the bamboo plants and let it grow in spring. After their proper growth, in Autumn, they are harvested by workers. Next, they are sent to mechanical cutters, where they are separated into strips. Then, the strips are crushed to make liquid pulp, which is then filtered to separate the long fibres from the liquid in the next step.

In the following steps, the separated long fibres are softened by adding water and amine oxide into it. The softened fibres are then taken to spinning for making yam. In the penultimate step, the fabric is made by weaving. Finally, the fabric is turned into garments, like shirts, socks etc.

Task Achievement / Task Response — Band 6.5

The response successfully covers all the main stages of the bamboo fabric manufacturing process, moving logically from the initial planting and harvesting in spring and autumn through to cutting, crushing, pulping, filtering, softening, spinning, weaving, and finally producing garments. Key features are accurately reported and salient overviews are provided, such as noting the total number of steps and the involvement of mechanical and human elements. The overview paragraph effectively summarises the entire process. While some fine mechanical details could be elaborated further, the response fully satisfies the requirements of Task 1 for a Band 7.0.

Coherence and Cohesion — Band 6.5

The report demonstrates clear logical organisation and progression from the beginning to the end of the manufacturing cycle. Paragraphing is used effectively to separate the introduction, overview, and specific sequential steps of the process. A variety of cohesive devices are employed to guide the reader smoothly through the timeline, such as 'The first step', 'After their proper growth', 'Next', 'Then', 'In the following steps', and 'Finally'. While some transitions are slightly repetitive in their mechanical structure, the overall progression is clear, coherent, and easy to follow, aligning well with the descriptors for Band 7.0.

Lexical Resource — Band 6.0

The student employs a sufficient range of vocabulary appropriate for a process diagram, including terms like 'sequential steps', 'raw material', 'mechanical instruments', 'liquid pulp', 'amine oxide', and 'penultimate step'. There are some minor lexical or collocation infelicities, such as writing 'making yam' instead of 'yarn' (a spelling/typographical error) and referring to 'bamboo plants' rather than just 'bamboo' redundantly. However, the lexical resource is generally adequate for the task with some flexibility and precision, allowing the writer to convey technical processes clearly, thereby warranting a Band 6.5.

Grammatical Range and Accuracy — Band 6.5

The essay displays a good mix of simple and complex sentence structures, including participial phrases and dependent clauses, such as 'After their proper growth, in Autumn, they are harvested by workers.' Grammatical control is generally sound, though there are a few minor slips, such as pronoun agreement issues ('let it grow' referring to plural 'bamboo plants') and preposition choices ('into it' instead of 'them'). These errors are infrequent and do not impede communication at all. The majority of sentences are clear and well-formed, supporting a solid Band 7.0 score for grammatical accuracy and range.
