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 process diagram illustrates how a bambo is used to make fabric.

Overall, the nine step process, consists of harvesting and crushing the bambo strips to make pulp, which is passed through a filter to separate fibres, that is then soften into a solution and finally converted into usuable fabric and commmercial products.

Firstly, bambo tress are planted in spring and havested in autumn. The plants are cut along their length into strips which are then crushed to make the liquid pulp. The pulp is passed through a filter that separates the ong fibres from the liquid.

The fibres are then soften by adding it to a solution of water and amine oxide. After softening these fibres, they are turned into a yarn by spining process. The yarn is used to make fabric by wearving process. This fabric can then be shaped into various commercial products such as shirts and sock.

Task Achievement / Task Response: Band 6.5

The response covers the main stages and gives a clear overview of the transformation from harvested bamboo to fabric and finished products. It accurately includes the seasonal planting and harvesting, cutting, crushing, filtering, softening, spinning and weaving. This breadth, together with the overview, shows good coverage of the task. However, some details are less precise: the fibres are softened by adding water and amine oxide, rather than by adding them to “a solution” as phrased here, and the final stage is described as shaping fabric into products, whereas the diagram simply shows clothing items as the end products. The overview could also make the process’s progression from plant material to yarn, fabric and clothing more explicit. More exact reporting of these details would strengthen an otherwise relevant summary.

Coherence and Cohesion: Band 7.0

The information is arranged in a clear sequence, with an overview followed by two paragraphs that trace the early processing stages and then the conversion of fibres into fabric and products. Sequencing expressions such as “Firstly,” “then,” and “After softening” help the reader follow the process, and the paragraph breaks are appropriate. The progression is generally easy to understand, although the overview’s long sentence combines several stages and contains unclear referencing: “fibres, that is then soften” makes it difficult to identify what “that” refers to. The transition from the overview to the detailed account is also somewhat repetitive. To make cohesion more flexible and precise, use shorter overview phrasing and ensure pronouns clearly refer to the material being described.

Lexical Resource: Band 6.0

There is an adequate range of process vocabulary, including “harvested,” “crushed,” “filter,” “fibres,” “pulp,” “yarn,” and “weaving,” which allows the stages to be communicated. Some less common technical language, such as “amine oxide,” is used appropriately. However, spelling errors are noticeable, including “bambo,” “havested,” “ong,” “usuable,” “commmercial,” “spining,” and “wearving.” There are also word-choice and collocation issues: “commercial products” is less precise than “clothing items,” and “turned into a yarn by spining process” is awkward. “Bamboo plants” and “bamboo strips” would also be more accurate than “bambo trees” and “bambo strips.” Careful proofreading and more natural process collocations would improve precision.

Grammatical Range and Accuracy: Band 6.0

The response uses a mix of simple and complex forms, including a passive construction (“are planted”) and a relative clause (“a filter that separates…”). Most relationships between stages remain understandable. Some grammatical errors nevertheless occur: the overview has faulty agreement and structure in “fibres, that is then soften,” while “the fibres are then soften” uses the wrong verb form. In “by adding it to a solution,” the pronoun does not agree clearly with the plural “fibres,” and “the nine step process, consists” has an unnecessary comma. These errors do not generally prevent understanding, but they limit accuracy. Review passive verb forms, subject–verb agreement, pronoun reference and punctuation, while retaining the useful variety of sentence structures already attempted.
