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 4.5)

The given process chart illustrates the process of making fabric.

This process involves 9 steps in total, all steps are essential, first of all, bamboo tree is planted then is harvested in autumn season, afterwards is cutted into strips, after that, strips are crushed in order to make liquid pulp subsequently, strips are filtered in order to make long fibres from liquid afterwards fibres are soften by adding water and amine oxide then, is spinned to make yarn, afterwards is weaved to make fabric at last the thread is spinned to make yarn

Task Achievement / Task Response: Band 4.0

You identify the process as involving nine steps and mention several relevant stages, including planting, autumn harvesting, cutting, crushing, filtering, softening, spinning and weaving. However, the account is incomplete and contains a significant sequence error: it ends by saying the thread is spun into yarn, repeating an earlier stage instead of reporting the final clothing items shown. The filtering description also reverses the relationship: the diagram shows long fibres being separated from liquid, not strips being filtered to make fibres. There is no clear overview of the process’s progression from growing bamboo to finished products. The response is also 57 words below the required minimum, which leaves important stages and details under-reported. Develop a complete, accurate summary of the start, processing stages and final products.

Coherence and Cohesion: Band 4.5

The stages are presented broadly in process order, and sequencing expressions such as “afterwards,” “after that” and “at last” help signal movement through the process. However, the response is written as one long sentence, so the reader has little help distinguishing the overview from the detailed stages. Several connectors are repeated, and the sequence becomes confusing where “subsequently” and “afterwards” are placed within already crowded clauses. The final statement also returns to spinning after weaving, disrupting the progression. Organise the response into a brief introduction and overview followed by clearly grouped stages, and use a smaller, more varied set of linking expressions to make the sequence easier to follow.

Lexical Resource: Band 5.5

You use some relevant process vocabulary, including “harvested,” “strips,” “liquid pulp,” “fibres,” “yarn” and “fabric,” which allows the reader to recognise the main subject and several stages. The range is nevertheless narrow and repetitive, with “afterwards” used more than once and “process” repeated. Some word choices or forms are inaccurate for the diagram: “process chart” is less suitable than “process diagram,” and “thread” is not the final product shown. Aim for more precise stage vocabulary, such as describing fibres as being separated from the liquid and garments as the finished products. A broader set of accurate verbs would make the account clearer and more natural.

Grammatical Range and Accuracy: Band 4.5

The response attempts to connect several stages in a longer sentence, but it relies almost entirely on a single chain of clauses and shows limited control of sentence boundaries. Errors include “bamboo tree is planted then is harvested,” where the subject is omitted from the second clause, and “fibres are soften,” which has an incorrect verb form. The passive construction is also incomplete in “then, is spinned,” and the sentence lacks punctuation to separate many stages. These problems sometimes make the relationships between actions difficult to follow. Use complete, shorter sentences with clear subjects and accurate passive forms, for example, “The bamboo is harvested in autumn” and “The fibres are softened by adding water and amine oxide.”
