Band 4+: Write a report for a university lecturer describing the information in the graph below. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The report provides a clear overview and covers the main trends in the data. However, there are some omissions and inaccuracies, such as not mentioning the 1970 data point (200 cases) and the 1995 data point (0 cases). Additionally, the description of the 1990 figure as 'the lowest point' is inaccurate since 1995 shows 0 cases. To improve, ensure all key data points are included and described accurately, and use more precise language to describe changes (e.g., 'increased sharply' instead of 'skyrocketed'). The report falls short of the required 150 words.

The report has a clear overall structure with an introduction and a general trend statement. However, the paragraphing is not skilfully managed; the body paragraphs are very short and could be better combined to improve flow. The use of cohesive devices like 'However' and 'While' is somewhat mechanical and occasionally disrupts the natural progression of ideas. To improve, consider grouping related time periods into fewer, more developed paragraphs and using a wider range of linking words and phrases more naturally.

The vocabulary used is adequate but limited in range. Words like 'figure', 'cases', and 'unchanged' are repeated, and the phrase 'skyrocketed' is informal for an academic report. There is some attempt at variation (e.g., 'incidences', 'hit the lowest point'), but overall the lexical resource lacks the flexibility and sophistication expected of a higher band score. To improve, use more precise and varied vocabulary (e.g., 'remained stable', 'peaked', 'plummeted', 'reached a low point') and avoid informal expressions. Boost vocabulary complexity to elevate the overall score.

The report contains several grammatical errors and awkward phrasing. For example, 'the figure increased at first before declining' is acceptable, but 'While after 1980 the cases of X disease in the chart went down' is grammatically incomplete and unclear. There is also a lack of sentence variety, with most sentences following a simple subject-verb-object structure. Punctuation is mostly correct, but the overall control of grammar is inconsistent. To improve, practice using a wider range of sentence structures (e.g., complex and compound sentences) and ensure each sentence is grammatically complete and clear.
