Task Achievement / Task Response: Band 4.5

You identify the process as having nine stages and mention the seasonal start, including planting in spring and harvesting in autumn. These details are relevant, but the account is very incomplete: it does not clearly report the full sequence from cutting and crushing through filtering, softening, spinning, weaving, and the final clothing items. Some stages are also placed in the wrong order: the diagram shows crushing before filtering and softening, whereas your response mentions softening before filtering and then crushing. The overview is unclear, and the response is 104 words, below the required 150. To improve, give a concise overview of the process and describe each stage accurately in sequence.

Coherence and Cohesion: Band 4.0

There is an attempt to present the process from its beginning to its end, and words such as “Overall,” “after that,” and “last” signal sequence. However, the ideas are not arranged into clear, complete sentences or paragraphs, so the reader has difficulty following the stages. For example, “after that soften fibres … however filter … the process made the bamboo then crush strips” combines steps in an unclear order, and “the spin to make yam from mixed weave” does not show how spinning leads to weaving. Use separate sentences for the growing and preparation stages, the fibre-processing stages, and the final production stages. Choose accurate sequence markers such as “next,” “subsequently,” and “finally.”

Lexical Resource: Band 5.0

You use several relevant process terms from the diagram, including “harvest,” “strips,” “fibres,” “liquid pulp,” “spin,” and “weave.” This gives the response some task-specific vocabulary, but the range is limited and several choices make the meaning difficult to understand. For instance, “yam” appears to be intended as “yarn,” while “mix the role” and “the ready for bamboo” do not communicate a clear process or product. “The stags” is also an inaccurate word choice for stages. Build a reliable set of process verbs and product nouns, and check spelling and collocations. More precise wording such as “produce yarn” and “finished clothing” would make the description clearer.

Grammatical Range and Accuracy: Band 4.0

The response attempts to describe a sequence and includes an overview opening, but grammatical control is very limited. Many clauses lack a clear subject or correctly formed verb, as in “after that soften fibres” and “the spin to make yam from mixed weave to make fabric.” The opening, “The diagram below illustrates the process by how bamboo fabric is made,” also has an incorrect sentence pattern. These frequent errors make relationships between stages difficult to follow. Practise writing complete simple sentences first, with a subject and verb—for example, “The strips are crushed to produce liquid pulp”—then connect them with sequence markers. Check verb forms, articles, and punctuation before submitting.
