Band 5+: The graph below shows the average monthly percentage change in the prices of three metals over a twelve-month period in 2014. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The report addresses the task by describing the general trends and some specific data points for the three metals. However, there are several inaccuracies and omissions that affect the overall clarity and completeness. For instance, the description of zinc's peak is incorrect (it peaked at 3% in February, not 1% in March), and the final value for copper is misstated (it was about 1.5% in December, not 1%). Additionally, the report lacks a clear comparison between the metals, which is a key requirement of the task. To improve, focus on accurately reporting the main features, such as the initial high for nickel, the subsequent decline and recovery, and the relative stability of copper and zinc. Also, ensure that all data points are correctly interpreted and that comparisons are made explicitly. Organize the information logically, perhaps by describing each metal in turn or by grouping similar trends, and avoid vague statements like 'fluctuated over the months' without specific support.

The report has a clear overall structure with an introduction and separate paragraphs for each metal, but the flow is sometimes disrupted by unclear referencing and abrupt transitions. For example, 'Then it declined significantly' lacks a clear subject, and 'After all' is used incorrectly. To improve, use clear cohesive devices (e.g., 'In contrast', 'Similarly') and ensure each paragraph has a clear topic sentence. Also, avoid vague phrases like 'over the month' and 'throughout the season'.

The vocabulary is adequate but limited, with some repetition and imprecise word choices. For instance, 'changing in the prices' is awkward, and 'cooper' should be 'copper'. There is some attempt at variety (e.g., 'declined significantly', 'rose steadily'), but more precise and varied language is needed. Use terms like 'fluctuated', 'peaked', 'plummeted', and 'remained stable' to enhance lexical range. Also, avoid informal phrases like 'the mid of May'. Boost vocabulary complexity to elevate the overall score.

The report contains several grammatical errors and awkward phrasing that affect clarity. Examples include 'all three metals are fluctuated' (should be 'fluctuated'), 'the highest changing' (should be 'the highest change'), and 'cooper decreased the rate' (should be 'copper's rate decreased'). There is some variety in sentence structures, but errors in subject-verb agreement and article usage are frequent. To improve, proofread carefully and practice using a range of complex structures with accuracy.
