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 process of making bamboo fabric, from planting bamboo plants to producing clothes.

Overall, there are nine stages in the process. It begins with the growing and harvesting of bamboo and ends with weaving the fibres into fabric, which is then used to make clothing. The process involves several mechanical and chemical steps to transform the raw bamboo into usable textile material.

Firstly, bamboo plants are planted in spring and harvested in autumn. After harvesting, the bamboo is cut into strips. These strips are then crushed to produce liquid pulp. Next, the pulp is filtered to separate the long fibres from the liquid.

After that, the fibres are softened by adding water and ammonium oxide. The softened fibres are then spun to make yarn. In the following stages, the yarn is woven to produce bamboo fabric. This woven material forms the main textile that can be used in the clothing industry. Finally, the fabric is used to make clothes, such as t-shirts and socks.

AI examiner evaluation

Task Achievement / Task Response — Band 8.0

The student successfully addresses all parts of the task by providing a clear summary of the process of manufacturing fabric from bamboo. The overview effectively captures the scope of the diagram, identifying the start and end points as well as noting that both mechanical and chemical steps are involved. All nine stages are accurately reported in the correct sequential order, from planting in spring through to the final production of clothing items like t-shirts and socks. There are no significant omissions or misinterpretations of the visual data, demonstrating a strong capability in selecting and reporting main features.

Coherence and Cohesion — Band 7.5

The response exhibits clear logical organization and progression throughout. Information is grouped sensibly into paragraphs that correspond to the logical phases of the process. Cohesive devices such as 'Firstly', 'After harvesting', 'Next', and 'Finally' are used appropriately to guide the reader through the sequence of events without feeling overly mechanical. Paragraphing is used sufficiently to separate the introduction, overview, and body steps clearly.

Lexical Resource — Band 7.0

The student uses a sufficient and appropriate range of vocabulary for the task. Words and phrases such as 'liquid pulp', 'separated', 'softened', 'spun', and 'woven' accurately describe the technical processes depicted in the diagram. There are only very minor stylistic points, such as referring to 'ammonium oxide' instead of the labeled 'amine oxide', though this does not impede communication. The vocabulary allows for clear and precise reporting of the stages.

Grammatical Range and Accuracy — Band 7.5

A good variety of sentence structures is utilized, featuring a mix of simple and complex forms with good control over passive voice constructions, which are essential for process descriptions (e.g., 'bamboo plants are planted', 'the bamboo is cut', 'the fibres are softened'). The majority of sentences are error-free, and punctuation is handled correctly throughout. Minor slips do not impede communication or detract from the overall clarity of the writing.
