Band 4+: The diagram illustrates the process of recycling glass bottles into new bottles.

The report addresses the task by describing the main stages of the glass recycling process, and it includes an overview. However, there are several inaccuracies and omissions: the initial collection mentions 'public area' and 'workers' which are not specified in the visual description, and the step of removing metal and plastic caps is described as 'placed in order' which is unclear. The report also omits the categorization of bottles by color (green, brown, clear) and the step of breaking the glass into pieces before melting. The language contains grammatical errors and awkward phrasing (e.g., 'demonstrate', 'artificial recycling', 'these stuff'), which affect clarity. To improve, ensure all key stages are accurately described, use precise vocabulary, and proofread for grammatical accuracy. The report falls short of the required 150 words.

The report has a logical structure with an introduction, overview, and body paragraphs, but the flow is disrupted by unclear referencing and abrupt transitions. For example, 'these stuff' and 'this material' are vague, and the sequence of steps is not always clear. To improve, use clear referencing (e.g., 'the collected bottles') and cohesive devices (e.g., 'subsequently', 'following this') to guide the reader smoothly through the process. Also, ensure each paragraph focuses on a distinct set of stages for better organization.

The vocabulary is adequate for the task but limited in range and precision. There are some inappropriate word choices (e.g., 'artificial' instead of 'artificial' or 'man-made', 'stuff' instead of 'materials', 'placed in order' instead of 'removed'). To improve, use more precise and varied vocabulary related to processes (e.g., 'undergo', 'convert', 'melt', 'mold') and avoid informal or vague terms. Also, ensure correct word forms (e.g., 'recycling' as a noun, 'recycled' as an adjective).

The report contains a mix of simple and complex sentences, but there are frequent grammatical errors that affect clarity. Examples include subject-verb agreement ('diagram demonstrate' should be 'diagram demonstrates'), tense inconsistency (e.g., 'were collected' vs. 'are collected'), and incorrect pluralization ('new one' should be 'new ones'). Punctuation is also inconsistent. To improve, review basic grammar rules, maintain consistent tense (e.g., present simple for processes), and proofread for errors. Using a wider range of structures, such as passive voice and relative clauses, would also enhance accuracy and flexibility.
