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 process by which bamboo is manufactured into fabric.

Overall, the process contains nine stages, beginning with the planting of bamboo plants in spring season and ending with the production of clothes. The raw bamboo gradually passing through several stages cutting, crushing, filtering, spining and then woven into fabric, which then used to make clothes.

Firstly, the bamboo plants are planted in spring season and then harvested after years of growth in autumn. At the next stage, bamboo is cut into strips. After that, the strips are crushed to make a liquid pulp, which leads to extraction of long fibres. Following this, these fibres are then separated from liquid pulp during filtering process in fifth stage.

In the sixth stage, the fibres are softened by using water and amine oxide. In the next stage, that softened material a thread spinned to make yarn. Subsequently, the thread is woven to make fabric. Finally, the fabric is used to manufacture clothing products such as socks and T-shirts.

Task Achievement / Task Response: Band 7.0

The response covers the full process and gives a clear overview of its nine stages, from planting in spring to finished clothing. It reports the main transformations accurately, including crushing the strips into pulp, filtering out long fibres, softening them with water and amine oxide, and then spinning and weaving. The final reference to socks and T-shirts is also supported by the diagram. This selection and coverage make the account clear and relevant. To strengthen the description further, make the overview more precise about the process’s broad phases—for example, cultivation and harvesting, fibre preparation, and conversion into fabric and garments. The phrase “harvested after years of growth” adds a duration not shown in the diagram, so avoid introducing unsupported detail.

Coherence and Cohesion: Band 7.0

The information is organised in a clear sequence, with an overview followed by stages described in order. Paragraphing separates the general summary from the detailed account, and transitions such as “Firstly,” “After that,” “Following this,” and “Finally” help readers track the process. The progression remains easy to follow even though the diagram’s arrows change direction between rows. Some linking is slightly repetitive, as several stages are introduced with similar sequencing phrases. There is also a small clarity issue in “which leads to extraction of long fibres,” followed by a separate explanation of filtering; the relationship between these steps could be expressed more directly. Use a few varied links that show cause or result, while keeping the sequence explicit.

Lexical Resource: Band 6.5

The response uses a suitable range of process vocabulary, including “harvested,” “crushed,” “liquid pulp,” “extraction,” “fibres,” and “woven.” These terms communicate the stages clearly, and the writer attempts more specific language than a basic list of actions. Some word choices and collocations are less natural or precise: “manufactured into fabric” is awkward for the opening, “production of clothes” is broad, and “thread” is not the clearest term for the material spun into yarn. There are also spelling errors in “spining” and “spinned.” These do not prevent understanding, but more accurate forms and natural process collocations would improve precision. Aim to use the diagram’s terminology consistently, especially for the fibre-to-yarn stage.

Grammatical Range and Accuracy: Band 6.0

There is a mix of simple and complex sentence forms, including relative clauses such as “which leads to extraction of long fibres” and time clauses that help describe the sequence. Most stages are expressed in a comprehensible way, but some grammatical errors remain. In the overview, “The raw bamboo gradually passing” lacks a finite verb, and “which then used to make clothes” needs an auxiliary. The sentence “that softened material a thread spinned” is also missing a clear verb structure. Articles and prepositions need attention in phrases such as “in spring season” and “during filtering process.” These errors rarely obscure the intended meaning, but proofreading for complete clauses and consistent passive constructions would improve control.
