Task Achievement / Task Response: Band 3.5

The response identifies the process as making fabric from bamboo and notes its seasonal beginning: “planting bamboo in spring” and harvesting “in autumn.” It also refers to filtering and adding chemicals, so some relevant stages are selected. However, the account is very incomplete: it omits cutting, crushing, spinning, weaving, and the final clothing products, and it does not explain the sequence clearly. The claim that the process ends with a “manufactured dress” is not quite accurate; the diagram shows clothing items, including a T-shirt and socks. The overview is limited, and the response does not meet the required minimum length, leaving the main features substantially under-reported. Describe the full sequence and its key transformations.

Coherence and Cohesion: Band 4.5

There is a basic attempt to organise the response, with an opening statement, an overview, and a paragraph about the process. The sequence from planting to harvesting is also signalled by “after growing bamboo.” However, progression then becomes difficult to follow: “there are some chemical need to mixed when bamboo got cut and before the filter” compresses several stages without explaining their order, and the final sentence stops at “adding,” leaving the idea unfinished. The paragraphing does not yet support a complete process description, and linking is limited. Use a clear chronological structure, with each stage connected to the next, and finish each sentence and paragraph with a complete idea.

Lexical Resource: Band 5.0

The response uses some relevant process vocabulary, including “harvested,” “filter,” “chemical,” and “planting,” which helps establish the topic. There is also an attempt to use more specific language such as “crucial material.” However, the range is limited, and several word choices or combinations are awkward, for example “manufactured dress by fabric” and “a difficult task to do.” “Plans” is also not the appropriate term for the process diagram. Build a more precise set of process verbs and material terms, such as “cut,” “crush,” “separate fibres,” “spin yarn,” and “weave fabric,” and use natural collocations to describe each transformation.

Grammatical Range and Accuracy: Band 4.5

The response attempts both simple statements and longer clauses, including “after growing bamboo its been harvested in autumn,” but grammatical control is inconsistent. Errors in agreement and verb forms appear in “The provided plans illustrates” and “the nine step … is start,” while “there are some chemical need to mixed” lacks a correct clause structure and auxiliary verbs. The sentence beginning “step 6 is important because” is also left incomplete, so the reader cannot understand the intended explanation. Capitalisation and punctuation are inconsistent, particularly at sentence beginnings. Practise accurate present-simple passive forms for process descriptions, such as “The bamboo is harvested,” and check subject–verb agreement, articles, and sentence completion.
