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 process of making bamboo fabric from bamboo plants.

Overall, the process consists of nine stages, beginning with the planting of bamboo plants and ending with the manufacture of clothes. The process involves several steps, including harvesting, crushing, filtering, softening, spinning and weaving.

Initially, bamboo plants are planted in spring and allowed to grow for a period of time before being harvested in autumn. Afterwards, the harvested bamboo is cut into strips and then crushed to make a slurry. Next, a filtering process is carried out to separate the long fibres from the liquid. Water and amine oxide are then added to the softened fibres, which helps prepare them for the next stage.

In the following stage, the fibres are spun into a thread or rope-like material for textile production. Following this, the resulting thread is woven together to form bamboo fabric. Finally, the fabric is processed into wearable clothes, completing the production process.

Task Achievement / Task Response: Band 6.5

The student provides a clear, well-structured overview of the entire manufacturing process, accurately reporting all nine key stages from planting to clothing production. The main features are successfully identified and described in a logical sequence. For instance, the transition from growing bamboo in spring to harvesting in autumn, followed by mechanical processing such as cutting and crushing, is correctly captured. The student also notes the chemical stage involving water and amine oxide correctly. While there is a slight reversal in the description of step 5 and step 6 in the third paragraph (stating that water and amine oxide are added before filtering, whereas the diagram shows filtering at step 5 and softening at step 6), the overall task is addressed very effectively. The response meets the 150-word requirement and covers all parts of the prompt well, earning a solid Band 7.0.

Coherence and Cohesion: Band 6.5

The response demonstrates a clear logical organisation and progression from the introduction through the sequential steps of the process to the final conclusion. Paragraphing is used appropriately to separate the introduction, the initial stages, and the final stages. Cohesive devices are employed effectively to guide the reader through the linear progression of the diagram, using transition words such as 'Initially', 'Afterwards', 'Next', 'In the following stage', and 'Finally'. Reference words are managed well, ensuring that the relationships between the steps remain clear throughout the text. Overall, the cohesion is natural and contributes to a smooth reading experience, fully satisfying the requirements for a Band 7.0.

Lexical Resource: Band 6.5

The student demonstrates a sufficient range of vocabulary appropriate for an Academic Task 1 process description. Words and phrases such as 'manufacture', 'process consists of', 'harvested', 'slurry', 'fibres', and 'textile production' are used accurately. There is an attempt to incorporate less common lexical items related to manufacturing, such as 'amine oxide' and 'woven together'. Word choice is generally precise, though some phrases like 'thread or rope-like material' are slightly informal or imprecise compared to the exact diagram label ('yarn'). However, spelling and word formation are accurate throughout, and communication is never impeded. This performance aligns comfortably with the Band 7.0 descriptors.

Grammatical Range and Accuracy: Band 6.5

The student displays a good control of grammar and punctuation, successfully utilising a variety of complex sentence structures alongside simple forms. Examples of complex structures include relative clauses and participial phrases, such as 'before being harvested in autumn' and 'which helps prepare them for the next stage'. The majority of sentences are error-free, and punctuation is handled correctly. While there are a few minor sequence issues noted in the task achievement analysis regarding the exact order of softening and filtering, the grammatical structures themselves are accurate and do not impede comprehension. The mix of structures and overall accuracy support a Band 7.0 rating.
