Task Achievement / Task Response: Band 4.5

You identify the subject as a nine-step recycling process and mention several relevant stages, including collection, sorting, compressing, crushing, washing, and producing pellets. However, the account only partially reports the diagram and some details are inaccurate or unclear. For example, the washing stage is described as cooling, and the explanation of pellets and raw material does not clearly match the sequence shown. The overview that bottles become “many other daily life products” is relevant, but the response does not clearly explain that the process forms a loop, with end products leading back to bottle disposal. To strengthen the report, summarise the full sequence accurately and include the key outputs shown, such as clothing, containers, and bags.

Coherence and Cohesion: Band 4.5

There is a basic attempt to move through the process in sequence, using phrases such as “afterthat,” “and then,” and “In the eight step.” This gives the reader some sense of progression. However, most information is placed in one long paragraph, and the links between stages are often unclear. The sentence beginning “However the compnies collect them” introduces a company that is not established in the diagram, while “the producing plastic pellets crush again” makes the relationship between crushing and pellet production difficult to follow. The final sentence also jumps to companies and recycling without clearly connecting the end products to the start of the cycle. Use separate overview and process paragraphs, with clear stage-to-stage links.

Lexical Resource: Band 4.5

The response uses some task-related vocabulary, including “recycling center,” “compressing into blocks,” “machine,” “plastic pellets,” and “raw material.” These terms show an attempt to describe the diagram rather than relying entirely on general language. However, the range is basic and several word choices or spellings make the meaning difficult to follow, such as “carbige truck,” “gets cool,” and “healing pellets.” Some expressions are also imprecise: “dustbin” does not clearly convey a recycling bin, and “high standards companies” is not supported by the diagram. Aim for accurate process vocabulary and check spelling carefully. More precise verbs such as “transported,” “sorted,” “shredded,” and “heated” would make the stages clearer.

Grammatical Range and Accuracy: Band 4.5

You attempt to connect ideas in longer sentences, for example by using “and then” and “where,” but sentence structures are limited and errors frequently obscure the process. Verb forms and agreement are often inaccurate: “The bottles are use,” “it gets sorts,” and “the raw material get preapred” need corrected forms. Articles and sentence boundaries are also inconsistent, as in “the producing plastic pellets crush again,” while the opening runs several ideas together without reliable punctuation. These problems make it hard to tell which material is being acted on at each stage. Practise building clear simple sentences first, then combine them with accurate clauses—for example, “The bottles are sorted, compressed into blocks and crushed.”
