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 given process diagram describes the manufacturing process of fabric from bamboo. In order to get wearable garments, it needs to go through several chemical and mechanical processes which starts from planting bamboo during Spring.

Firstly, bamboo is planted in the ground in Spring. Once the bamboo reaches a certain height, it is harvested during Autumn. After harvesting, it is transfered to factory and cut into strips which then is crushed in order to make liquid pulp. To separate long fibres from liquid, the cruhed strips are gone through filtration process. As the next step, water and amine oxide are added so that the fibres are softened. Then comes the spinning process, by which these soften fibres are made into yarn. Following this process, yarn are woven into fabric. Finally, this fabric is used to produce wearable clothings such as tshirts, socks and other garments products.

Overall, nine linear mechanical and chemical steps are followed in order to produce wearable clothing from raw material which is first planted on the ground as bamboo.

Task Achievement / Task Response: Band 6.5

The response covers the main stages in the correct order, from spring planting and autumn harvesting through processing, spinning, weaving and the final clothing products. It also includes a relevant overview identifying a nine-step process and the transformation from bamboo into garments. These features make the account clear and substantially complete. However, the overview is somewhat repetitive of the introduction, and some details are less precise: the diagram does not state that bamboo reaches a “certain height” before harvesting or that it is transferred to a factory. The final step shows a T-shirt and socks, so “other garments” is a reasonable generalisation, but the response could make the key transformation and the sequence of mechanical and chemical stages more clearly prominent.

Coherence and Cohesion: Band 6.5

The information is arranged in a logical sequence, and the paragraph beginning “Firstly” follows the process from cultivation to finished clothing without disrupting the reader’s understanding. Sequencing expressions such as “After harvesting,” “As the next step,” “Then,” and “Finally” help connect the stages. The separate concluding overview also gives the response a recognisable structure. However, the overview repeats the introduction’s focus on producing garments, and the repeated use of step-by-step transitions makes cohesion somewhat mechanical. The reference in “Following this process” is also broad rather than identifying the preceding spinning stage. Grouping the stages into cultivation, fibre processing, and fabric production would create more flexible progression and reduce reliance on formulaic connectors.

Lexical Resource: Band 6.0

The response uses an adequate range of process vocabulary, including “harvested,” “liquid pulp,” “filtration,” “fibres,” “spinning,” and “woven.” These terms communicate the stages clearly, and the writer attempts more specific language such as “chemical and mechanical processes.” Some word choices and collocations are less natural or precise, however: “wearable clothings,” “garments products,” and “gone through filtration process” do not fit standard usage. There are also spelling errors in “transfered,” “cruhed,” and “tshirts.” Use concise, conventional process descriptions—for example, “is filtered” and “the fabric is made into clothing”—and check spelling and countability. This would make the vocabulary more accurate while retaining the useful technical terms already present.

Grammatical Range and Accuracy: Band 6.0

There is a mix of simple and complex sentence forms, including a purpose clause in “in order to make liquid pulp” and a relative clause in “which then is crushed.” Most stages remain understandable, and the writer generally maintains a suitable present-tense process description. Some grammatical errors persist, particularly with agreement and verb forms: “which starts” should agree with the plural “processes,” “which then is crushed” has an unclear singular reference, “these soften fibres” needs a past participle, and “yarn are woven” requires singular agreement. Articles are also missing in “transfered to factory” and “gone through filtration process.” Greater control of agreement, articles, and passive constructions would improve accuracy without sacrificing sentence variety.
