Band 4+: You should spend about 20 minutes on this task. The given diagram shows the recycling process of glass bottles. Summarise the information by selecting and reporting the main features and making comparisons where relevant. Write at least 150 words.

The report addresses the task by describing the main stages of the glass bottle recycling process, and it includes an overview. However, there are some inaccuracies and omissions: the second purification stage is not mentioned, and the final step is described as 'close them by a lid,' which is not part of the process. The language is somewhat repetitive and lacks clarity in places, but the overall structure is logical. To improve, ensure all key stages are accurately covered and avoid adding irrelevant details. Use more precise vocabulary and vary sentence structures for better coherence. 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 abrupt transitions and inconsistent use of capitalization. The overview is vague and does not clearly summarize the main stages. The body lacks clear paragraphing and cohesive devices, making it difficult to follow the sequence of steps. To improve, use clear paragraph breaks for each stage, employ linking words (e.g., 'first', 'then', 'subsequently', 'finally'), and ensure the overview provides a concise summary of the process.

The vocabulary is basic and repetitive, with limited range. Some phrases are awkward or unclear, such as 'specific staffs', 'certain places', and 'transform them as a complete object'. There is an attempt to use process-related terms (e.g., 'purification', 'optoelectronic system', 'cullet melting'), but they are not used with precision. To improve, use a wider range of precise vocabulary (e.g., 'undergo', 'subsequently', 'convert', 'manufacture'), and avoid informal or vague expressions. Ensure that technical terms are used accurately and appropriately.

The report contains numerous grammatical errors and punctuation issues, which significantly affect clarity. There are subject-verb agreement errors (e.g., 'the glass will be melt'), incorrect verb forms (e.g., 'is going through' instead of 'goes through'), and missing articles. Punctuation is inconsistent, with excessive use of capital letters and missing commas. The sentence structures are mostly simple and repetitive. To improve, focus on using a variety of complex structures, ensure subject-verb agreement, and correct verb tenses. Pay attention to punctuation, especially capitalization and comma usage, to enhance readability.
