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 7.5)

The diagram illustrates the step-by-step process of manufacturing fabric and clothing items from natural bamboo plants.

Overall, the manufacturing process comprises nine distinct stages, beginning with the cultivation and harvesting of raw bamboo and culminating in the production of finished textile products like shirts and socks. The operation transforms solid stalks into liquid pulp, extracts soft fibers, and ultimately converts them into woven fabric.

In the initial agricultural phase, bamboo plants are sown during spring and left to grow until autumn, when they are harvested.The harvested stalks are then mechanically cut into thin strips using a power saw. In the fourth stage, these bamboo strips are thoroughly crushed to produce a liquid pulp. Then, they are filtered to separate long fibres from liquid. Next, these separated fibers are treated in a solution of water and amine oxide, which softens them. In the final mechanical process, those softened fibres are spinned to form yarns, which are subsequently woven into sheets of fabric. Lastly, this finished fabric is used to manufacture various items of clothing, such as socks and t-shirts.

Task Achievement / Task Response: Band 7.5

The student covers all parts of the task well, providing a clear and comprehensive summary of the process of manufacturing bamboo fabric. The response successfully highlights the main features and stages, beginning with the cultivation of bamboo in spring and concluding with the production of clothing items like socks and t-shirts. The overview section accurately outlines the general nature of the 9-stage process, distinguishing between agricultural, mechanical, and chemical phases. All relevant details, including the crushing of strips, filtering of pulp, softening with water and amine oxide, spinning, and weaving, are faithfully reported without any significant omissions or misinterpretations of the provided diagram. The response meets all requirements for Task Achievement at a high level.

Coherence and Cohesion: Band 7.5

The response demonstrates a clear logical organisation and progression throughout. Ideas are logically sequenced, mirroring the step-by-step nature of the diagram from raw material to finished product. Paragraphing is used effectively and appropriately, separating the introduction, an overview paragraph, and the detailed body paragraph. Cohesive devices such as 'In the initial agricultural phase', 'Then', 'Next', and 'Lastly' are used flexibly to guide the reader through the various stages of the manufacturing process without any mechanical repetition or confusion.

Lexical Resource: Band 6.5

The student displays a sufficient and flexible range of vocabulary suited to a process diagram. Appropriate less common and process-specific lexical items are utilised effectively, such as 'cultivation', 'harvested', 'mechanically cut', 'liquid pulp', 'amine oxide', and 'woven fabric'. Word choice and collocations are generally accurate. There is only a minor lexical slip in the use of 'spinned' instead of 'spun', but overall the vocabulary demonstrates good awareness of style and precision for Academic Task 1.

Grammatical Range and Accuracy: Band 7.5

The text employs a good variety of complex sentence structures alongside simple forms, showing good control of grammar and punctuation. Examples include relative clauses and participial phrases used to link stages together, such as 'beginning with the cultivation and harvesting of raw bamboo and culminating in the production of finished textile products'. The majority of sentences are error-free, with only a single notable morphological slip ('spinned' instead of 'spun'). Punctuation is accurate, and control over tense and voice (principally the present simple passive, appropriate for describing processes) is well maintained throughout the text.
