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 production of fabric from bamboo plants.

Overall, it can be seen that the plantation of bamboos plant during Spring, followed by its harvestation in Autumn, which further undergoes several mechanical and chemical processes from cutting sticks into long fibres to soften it, resulting in the production of yarn, which is then used to make fabrics.

At the beginning, the bamboo plants are planted in Spring and harvested during Autumn. The stem is then cut into long strips followed by its crushing to form liquid pulps. The pulp then passes through a filtration process which is used to separate long strips from liquid. The subsequent addition of water and amine oxide softens the fibre.

At step 7, the fibres then spin resulting in the formation of yarn, which is then weaved to make fabric. This fabric is further converted into different types of goods including shirts and socks.

Task Achievement / Task Response — Band 6.5

The student successfully covers all the main steps of the process diagram, from planting bamboo in Spring to the final manufacturing of fabric and clothing items like shirts and socks. The overview sentence effectively captures the general nature of the process, noting that it involves mechanical and chemical stages leading to yarn and fabric production. However, there are minor inaccuracies in reporting the order and details of the steps; for instance, the text states that crushing the bamboo forms liquid pulps which are then filtered to 'separate long strips from liquid', whereas the diagram indicates filtering separates long fibres from the liquid. Additionally, the overview contains a grammatical slip ('plantation of bamboos plant') rather than a pure task failure. Overall, the response addresses all parts of the prompt adequately and presents a clear picture of the process, satisfying the requirements for Band 6.5 or 7.0, with solid feature selection.

Coherence and Cohesion — Band 7.0

The response is logically organised into four distinct paragraphs: an introduction, an overview, and two body paragraphs detailing the sequential steps of the process. Cohesive devices are used to guide the reader through the stages, such as 'At the beginning', 'The pulp then', and 'At step 7'. However, some cohesive transitions and referencing feel a bit mechanical or slightly awkward, such as 'which further undergoes several mechanical and chemical processes' modifying the harvestation rather than the bamboo itself. Paragraphing is used appropriately, and the overall progression follows the linear flow of the diagram clearly. This level of organisation aligns well with the Band 7 descriptor for logical flow and sufficient cohesion.

Lexical Resource — Band 6.0

The student demonstrates an adequate range of vocabulary suitable for describing a manufacturing process, employing terms such as 'production', 'mechanical and chemical processes', 'filtration process', and 'subsequent addition'. However, there are notable word-choice and morphological errors throughout the text, such as 'plantation of bamboos plant' instead of 'planting of bamboo', 'harvestation' instead of 'harvesting', and 'weaved' instead of 'woven'. While these lexical inaccuracies and non-standard forms do not impede communication, they restrict the score to Band 6, as the vocabulary lacks the precision and natural control required for higher bands.

Grammatical Range and Accuracy — Band 6.0

The response features a mix of simple and complex sentence structures, including relative clauses and passive constructions (e.g., 'the bamboo plants are planted', 'which is then used to make fabrics'). There are, however, several grammatical errors and awkward syntactic structures, such as 'it can be seen that the plantation of bamboos plant during Spring, followed by its harvestation...', which lacks a main finite verb for the subject clause. Other minor errors include 'the fibres then spin' (should be passive 'are spun') and 'weaved' (woven). These errors occasionally disrupt the flow but do not impede overall comprehension, placing the response solidly in the Band 6 category.
