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 following diagram illustrates the various stages involved in production of fabric from bamboo, beginning with cultivation of bamboo plant and ending with manufacture of clothes.

Overall, the process consists of nine stages and includes both agricultural and industrial procedures. The treatment transforms raw bamboo into soft and usable fibres suitable for the stage of fabric production.

Initially, bamboo is planted in spring and harvested in autumn once it has matured. The harvested plants are then cut into strips, which are subsequently crushed to produce a liquid pulp.

Next, the pulp is filtered to separate the long fibres from the liquid. These fibres are then softened by adding water and amine oxide, preparing them for the next stage of production.

Following this, the softened fibres are spun into yarn. The yarn is then woven to create fabric, which is finally used to manufacture clothing such as shirts and other garments.

There is no evidence of mechanical or repetitive use of linking words, and the overall structure is well-managed.

Lexical Resource — Band 6.5

The vocabulary is accurate and appropriate for a process description. Terms such as 'cultivation', 'matured', 'subsequently', 'crushed', and 'garments' demonstrate a sufficient range for the task. The student uses technical terms correctly in context. While the vocabulary is functional and precise, it could be slightly more sophisticated to reach the highest band. However, the current range is more than adequate for the task, and there are no errors in word choice or collocation that impede communication or cause confusion.

Grammatical Range and Accuracy — Band 7.5

The response displays a good variety of complex structures, such as the use of passive voice ('bamboo is planted', 'pulp is filtered') which is highly appropriate for describing a manufacturing process. Sentence structures are varied, and the majority of sentences are error-free. Punctuation is used correctly throughout. There are no significant grammatical errors, and the control over complex sentence forms is consistent. The writing is clear and flows well, demonstrating a high level of grammatical accuracy and flexibility.
