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 5.0)

The diagram illustrates the process of bamboo fabric production and gives us an overview of all the steps involved.

The bamboo fabric consists of 9 steps. In the first step the bamboo plants are planted in the spring season as it is the best time for plantation. The bamboo reached their full growth rate in autumn, and in this season the bamboos are being harvested. In the 3rd step that is the cutting phase, in this the bamboo are cut into small strips.

The strips are then crushed in big machines to extract the liquid pulp of bamboo. Then the liquid is filtered to separate any long fibers left in the liquid pulp. Water along with amine oxide, a chemical is added in the later steps to soften the fibers. Then the fibers goes through a spinning process, to make yarn from it. Then in the l

Task Achievement / Task Response: Band 4.0

You identify the process and report several accurate stages, including planting in spring, harvesting in autumn, cutting, crushing, filtering, softening and spinning. However, the response is incomplete: it stops mid-sentence at “Then in the l” and does not describe weaving or the finished clothing shown in the final stage. There is also no clear overview of the process’s full progression from growing bamboo to making fabric and garments. The claim that autumn is when bamboo reaches its “full growth rate” is not stated in the diagram, and the reason given for spring planting is also invented. The response is 147 words, below the required 150. To improve, cover all nine stages, give a concise overview, and avoid adding explanations not shown.

Coherence and Cohesion: Band 5.0

The stages you do mention are generally presented in the correct order, and linking words such as “Then” and “The strips are then” help the reader follow the process. The paragraphing is limited, however, and the response ends abruptly in the middle of a sentence, so the sequence has no proper conclusion. Repeated use of “Then” also makes the progression feel mechanical, while phrases such as “In the 3rd step that is the cutting phase, in this…” interrupt the flow and repeat information. Organise the response into an introduction and overview followed by a clearly sequenced description of the stages. Use varied, precise transitions and complete the final stages to create a coherent progression.

Lexical Resource: Band 6.0

You use an adequate range of process vocabulary, including “harvested,” “crushed,” “liquid pulp,” “filtered,” “fibers,” and “spinning process.” These terms make most of the manufacturing stages understandable, and “amine oxide” is appropriately specific. Some choices are imprecise or informal for an academic process description: “big machines” is vague, “extract the liquid pulp” is not the clearest description of crushing, and “full growth rate” does not accurately express what the diagram shows. There is also repetition of “steps,” “bamboo,” and “Then.” Aim for more precise process collocations, such as “crush the strips to produce pulp” and “separate the long fibres,” and vary your vocabulary without introducing unsupported details.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and more complex sentence forms, and several sentences communicate the sequence clearly, for example, “The strips are then crushed… to extract the liquid pulp of bamboo.” However, some errors in agreement and sentence construction remain. In “The bamboo reached their full growth rate,” the plural pronoun does not agree with “bamboo”; “the fibers goes” should use a plural verb; and “in this the bamboo are cut” has faulty clause structure and agreement. The phrase “In the first step the bamboo plants are planted…” also repeats the same idea awkwardly. Use a consistent present simple passive for process stages, check subject–verb agreement, and revise incomplete or repetitive clauses. The unfinished final sentence further prevents the grammar from being assessed as a complete description.
