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 the nine different steps which are involved in manufacturing fabric from bamboo plants.

Overall, the procedure follows a linear multi-stage sequence that starts with planting the bamboo in the spring and ends with fabric used to produce shirts and socks.

In the initial stages, the process starts when the bamboo is planted during spring. It then harvested in autumn when it becomes ready and raw enough. After that, bamboo is cutted into strips, which are then crushed into small fragments to obtain the liquid pulp. Once the liquid component has been extracted from crushed strips, then the liquid is filtered to separate the long fibers from it.

In the last stages, in order to gain soft fibers, water and amine oxide are added. After that, the fibers are spun in order to make a ball of yam. After this stage has been completed, the yam is then processed into weaved fibric. Finally, the fabric is ready now to be processed into shirts or socks.

Task Achievement / Task Response: Band 7.0

The response gives a clear overview of the process, identifying its start in spring planting and its endpoint in clothing, and it reports the main stages from harvesting through cutting, crushing, filtering, softening, spinning and weaving. These details are generally grounded in the diagram, and the sequence is mostly accurate. However, the description of filtering is unclear: the diagram shows long fibres being separated from liquid, whereas the response says the liquid is extracted and then filtered, which can suggest the reverse. The final stage is also described as fabric being processed into shirts or socks, rather than simply showing finished clothing. More precise reporting of these stages would strengthen an otherwise complete account.

Coherence and Cohesion: Band 6.5

The response is organised into an introduction, an overview and two chronological body paragraphs, so the reader can follow the process from cultivation to finished products. Sequencing phrases such as “In the initial stages,” “After that” and “Finally” help establish progression. This is a coherent overall arrangement, but some linking is mechanical or repetitive: “After that” and “After this stage” occur close together, and “Once … then” creates an awkward transition. The filtering explanation also makes the relationship between the liquid and fibres difficult to follow. To improve cohesion, use a wider range of concise transitions and make each stage’s relationship to the previous one explicit, especially where material is separated or transformed.

Lexical Resource: Band 6.0

There is an adequate range of process vocabulary, including “harvested,” “crushed,” “liquid pulp,” “filtered,” “fibers,” “spun” and “weaved.” These terms allow the reader to understand most stages, and the response attempts some more specific language. However, several word-choice, collocation and spelling problems reduce precision: “raw enough” is not a natural description of bamboo ready for harvesting, “yam” is used for yarn, and “fibric” is an inaccurate form for fabric. “Cutted” is also an incorrect word form, while “gain soft fibers” is less natural than describing the fibres as being softened. Check technical vocabulary and spelling carefully, and prefer precise process collocations over improvised phrases.

Grammatical Range and Accuracy: Band 6.0

The response uses a mix of simple and complex forms, including a relative clause in “strips, which are then crushed” and a time clause beginning “Once the liquid component…”. Most stages remain understandable despite some grammatical errors. For example, “It then harvested in autumn” is missing the auxiliary “is,” and “the process starts when the bamboo is planted” is followed by several sentences with repetitive structures. The “Once … then” construction is also awkward, and “the fabric is ready now to be processed” has an unnatural placement of “now.” Aim for more consistent passive forms when describing a process, and review auxiliary verbs, clause construction and adverb placement. Greater control of these patterns would make the account smoother and more accurate.
