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 7.0)

The given diagram illustrates the manufacturing process of fabric from the bamboo plant. Overall, the process is linear and consists of nine major stages, beginning with the plantation and harvesting of the bamboo plant and ending with the production of fabric to make different garments. It involves both mechanical and chemical procedures.

Initially, the bamboo plants are planted in a field during the Spring. After plants reach the suitable growth stage, they undergo harvesting process in Autumn, which is performed manually. Bamboos are then cut into small strips with the help of a cutting machine and crush into pieces to make liquid pulp, which is subsequently transferred for filtration. Now, the obtained liquid pulp are filtered in order to separate long fibres from liquid.

In the subsequent stages, extracted fibres are softened by the addition of water and amino oxide. Once softened, these fibres are spun in order to produce a yarn and later these yarns are woven to make fabrics. In the final stage , these fabrics are used to make garments such as t-shirts and socks.

AI examiner evaluation

Task Achievement / Task Response — Band 7.0

The response effectively covers all stages of the bamboo manufacturing process, from plantation to the final product. You have successfully identified the main features and provided a clear overview in the introduction. The logical progression of the process is well-maintained throughout the report. To reach a higher band, ensure that you explicitly mention the specific chemical agents or mechanical actions mentioned in the diagram (such as the 'amino oxide' and 'filtration') with even more precision. Overall, the task is addressed well, and the information is accurately reported without any significant omissions.

Coherence and Cohesion — Band 7.5

The response is logically organized, with a clear introduction followed by a chronological description of the process. Paragraphing is used effectively to separate the different stages of production. You have used a variety of cohesive devices such as 'Initially', 'subsequently', 'In the subsequent stages', and 'In the final stage' to guide the reader through the process. The flow of information is smooth, and the progression from one step to the next is easy to follow. The use of referencing is generally clear, contributing to a coherent and well-structured response.

Lexical Resource — Band 6.5

You have used a good range of vocabulary appropriate for a process description, such as 'manufacturing process', 'linear', 'harvesting', 'filtration', and 'extracted'. There is a good level of precision in your word choice. However, there are minor issues with collocation and word form, such as 'undergo harvesting process' (should be 'undergo the harvesting process') and 'crush into pieces' (should be 'crushed into pieces'). Despite these minor slips, the vocabulary is sufficient to convey the information clearly and accurately throughout the text.

Grammatical Range and Accuracy — Band 6.0

The response demonstrates a mix of simple and complex sentence structures. You have used passive voice appropriately for a process description, such as 'bamboo plants are planted' and 'liquid pulp are filtered'. However, there are some grammatical errors, such as subject-verb agreement in 'the obtained liquid pulp are filtered' (should be 'is filtered') and 'crush into pieces' (should be 'are crushed'). While these errors are noticeable, they do not impede communication. Increasing the frequency of error-free complex sentences would help in achieving a higher band score.
