Task Achievement / Task Response — Band 7.5
The response covers all requirements of the task. You have identified the main features and provided relevant comparisons, such as noting that Nickel was the most volatile while Copper was the most stable. The overview is clear and highlights the key trends effectively. However, the description of Zinc is slightly underdeveloped compared to the other two metals, as the final part of the year for Zinc is not fully detailed in relation to the others. To reach a higher band, ensure that all data points mentioned in the graph are fully integrated into your comparative analysis, ensuring a balanced treatment of all three categories throughout the reporting period.
Coherence and Cohesion — Band 8.0
The response is logically organized with a clear introduction, a concise overview, and separate paragraphs for the body content. Cohesive devices such as 'In addition', 'At the beginning of the year', and 'After another small decline' are used effectively to guide the reader through the trends. Paragraphing is used appropriately to separate the overview from the detailed analysis. The progression of ideas is clear, moving from a general summary to specific monthly fluctuations. The flow is smooth, and the information is presented in a way that is easy to follow, meeting the requirements for a well-structured report.
Lexical Resource — Band 7.5
You have used a sufficient range of vocabulary to describe the trends, including terms like 'fluctuations', 'stable trend', 'recovered', and 'declined'. The language is generally precise and appropriate for an academic report. There are no significant spelling errors, and the word choices are accurate for the context of describing graph data. To improve, try to incorporate more varied synonyms for 'increase' and 'decrease' to avoid repetition, and use more sophisticated collocations to describe the degree of change, such as 'marginal recovery' or 'pronounced volatility'.
Grammatical Range and Accuracy — Band 7.5
The response demonstrates a good mix of simple and complex sentence structures. Most sentences are error-free, and your control of grammar is generally strong. There are a few minor punctuation issues, such as the period placed before 'between July and September' in the third paragraph, which disrupts the sentence structure. Additionally, ensure consistent use of articles and prepositions when describing data points. Despite these minor slips, the meaning is always clear, and the grammatical errors do not impede communication. The use of complex structures is sufficient for this task.
