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 4.0)

The diagram illustrates the process of the fabric that is manufactured from bamboo.

Overall, it is clear that this process consisted on nine stages, from planting process to weave including harvesting, filtration, crush strips and spin.

Firstly, the bamboo plant planted in the spring season, then it harvest in the Autumn season. After that, it cu

Task Achievement / Task Response: Band 3.0

The response identifies the topic and gives a basic overview that the process has nine stages, beginning with planting and ending with weaving. It also correctly mentions spring planting and autumn harvesting. However, the account stops partway through the process (“After that, it cu”), so most stages—including cutting, crushing, filtering, softening, spinning, weaving and the finished clothing—are not reported. The overview is also incomplete and does not clearly summarise the main transformation from bamboo plants into fabric and clothing. The response is substantially below the required 150 words, which leaves the task only minimally addressed. To improve, describe the full sequence and include a concise overview of its beginning, processing stages and final products.

Coherence and Cohesion: Band 4.5

There is a basic attempt to organise the response: an opening sentence, an overview, and a sequence introduced by “Firstly” and “After that.” These signals show an intended progression through the process. However, the response ends abruptly in the middle of a word, so the sequence cannot be followed beyond the initial stages, and there is no concluding account of the later steps. The overview also lists selected stages without explaining how they connect. Use separate paragraphs for the overview and the detailed process, then guide the reader through every stage with clear sequencing expressions such as “next,” “subsequently” and “finally.” Complete sentences and a finished ending would make the progression much clearer.

Lexical Resource: Band 4.5

The response uses some relevant process vocabulary, including “manufactured,” “harvesting,” “filtration,” “crush strips” and “spin,” so the topic is recognisable. However, the range is limited by the very short response, and several choices are awkward or imprecise: “planting process” is not a natural description of the first stage, while “filtration” does not clearly identify the action of separating fibres from liquid. “Weave” is also used where the noun “weaving” would fit the overview more naturally. Aim for precise process terms such as “cut into strips,” “crush the strips into pulp,” “filter the mixture,” “soften the fibres” and “spin them into yarn.” This vocabulary will help distinguish the stages and describe the transformation accurately.

Grammatical Range and Accuracy: Band 4.5

The response attempts both simple and more extended sentence forms, including a sequence joined with “then” and “after that.” However, grammatical control is uneven. In “this process consisted on nine stages,” the preposition and tense are incorrect; use “consists of nine stages” for a general process. “The bamboo plant planted” is missing an auxiliary verb, and “then it harvest” has an incorrect verb form. The final sentence is incomplete, ending with “cu,” which prevents the reader from understanding the intended stage. Use the present simple consistently for a process diagram, check subject–verb forms, and ensure each sentence is complete. A wider range of accurate sentence patterns would also help explain the stages and their relationships.
