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 diagram illustrates the manufacturing of fabric from bamboo. Overall, it is a 9-step process, which begins with the planting of bamboo plants and concludes with the formation of fabrics. However, the eight intermediate steps play the most pivotal role in the transformation of bamboo into the fabric.

In the agriculture phase, during the spring season, bamboos are planted to initiate the procedure. Whereas the harvesting of bamboo crops occurs in the autumn, followed by cutting them into small pieces with the help of fine sharp cutters. Then liquid pulp is extracted from these strips by crushing them.

The industrial stage of fabric synthesis starts with filtration, which involves the separation of long fibers from liquid. Then compounds like water and amine oxide are introduced to soften fibers. Furthermore, spinning helps to make yarn of soft fibers. The weaving is the penultimate step of this process which leads to the formation of plain fabric which can be used to make various clothes.

Task Achievement / Task Response — Band 6.5

The student successfully addresses all parts of the task by outlining the main features of the bamboo manufacturing process, from planting to fabric formation. An adequate overview is provided in the introduction, noting the 9-step nature of the process and the intermediate stages. Key steps such as harvesting, cutting, crushing, filtering, softening, spinning, and weaving are accurately reported and sequenced logically. For instance, the student correctly highlights the transition from agricultural steps to industrial phases like filtration and spinning. The selection of information is generally comprehensive and matches the visual data closely, although minor details such as the final clothing items depicted in step 9 are only briefly touched upon. Overall, the response meets the requirements for Task Achievement well, demonstrating a clear understanding of the diagram's progression and key features without omitting essential information.

Coherence and Cohesion — Band 6.5

The response exhibits a clear logical organisation and progression throughout. The information is logically sequenced from the agricultural phase to the industrial stage, following the chronological order of the diagram. Cohesive devices are used reasonably well to guide the reader through the steps, employing transitional phrases such as "Overall," "Whereas," "Then," and "Furthermore." Paragraphing is used appropriately to separate the introduction and overview from the detailed body paragraphs, although the division between the agricultural and industrial phases could have been structured into distinct paragraphs for even better visual flow. Referencing is generally clear, and the overall progression makes the text easy to follow, supporting a solid band 7 level of coherence and cohesion.

Lexical Resource — Band 6.5

The student demonstrates an adequate to good range of vocabulary suited to a process description, successfully incorporating less common lexical items such as "intermediate steps," "pivotal role," "synthesis," "filtration," and "penultimate." Word choice is generally appropriate, as seen in expressions like "extraction from these strips" and "soften fibers." However, there are a few minor lexical awkwardnesses or slight inaccuracies in collocation, such as writing "bamboos are planted" (more naturally "bamboo is planted" or "bamboo plants are put in the ground") and "weaving is the penultimate step" where an article is missing before weaving. Spelling is accurate throughout, and communication is never impeded, placing the vocabulary firmly in the band 7 territory.

Grammatical Range and Accuracy — Band 6.5

The student uses a mix of simple and complex sentence structures, including subordinate clauses introduced by "which" and prepositional phrases indicating time and manner (e.g., "with the help of fine sharp cutters," "which leads to the formation of plain fabric which can be used..."). There are frequent error-free sentences, and the overall control of grammar and punctuation is good. A few minor grammatical slips occur, such as the omission of an article in "The weaving is the penultimate step" and the pluralization of "bamboos," but these errors do not impede communication. Complex structures are attempted with reasonable success, justifying a band 7 for grammatical range and accuracy.
