Task Response

The report covers the main points of the task, providing a general overview and some specific data. However, there are some omissions and inaccuracies in the data reported. To improve, ensure all key data points are accurately represented and consider a more structured approach to comparing the two pie charts.

Coherence & Cohesion

The report demonstrates an adequate attempt to organize the information, but the flow could be improved. The introduction is clear, but the body paragraphs lack clear topic sentences and transitions between ideas. Consider using more cohesive devices to link sentences and paragraphs, such as 'similarly,' 'in contrast,' or 'furthermore.' Paragraphing could be improved by grouping information more thematically.

Lexical Resource

The vocabulary used is generally appropriate, but there's room for improvement in terms of variety and precision. For instance, instead of repeatedly using 'reliance,' you could use synonyms like 'dependence,' 'usage,' or 'consumption.' Try to incorporate more specific vocabulary related to energy sources and trends to enhance the report's sophistication.

Grammatical Range & Accuracy

The report contains several grammatical errors that affect clarity. Errors include incorrect verb tenses ('changes have occured'), subject-verb agreement issues, and misuse of articles. Sentence structure is relatively simple, limiting the demonstration of a wide range of grammatical structures. Focus on proofreading for common errors and practicing more complex sentence constructions.
