Task Response

The report effectively summarizes and compares the data presented in the pie charts. The overview is clear, and the main trends are identified. The report also includes relevant details and makes appropriate comparisons between the two years. To improve, consider including more specific data points to support your claims and ensure that all categories are mentioned, even briefly, for completeness.

Coherence & Cohesion

The report is generally well-organized, with a clear overview and specific details. However, the transitions between some sentences could be smoother to improve the flow. Consider using a wider range of cohesive devices to link ideas more effectively. For example, in the second paragraph, you could add a transition word or phrase to connect the overall trend of air pollution with the increase in domestic sewage.

Lexical Resource

The report demonstrates a good range of vocabulary related to pollution and environmental issues. However, there's room to enhance the sophistication of word choices. For instance, instead of repeatedly using 'pollution,' you could incorporate synonyms like 'contamination' or 'effluents' to add variety. Also, consider using more precise language to describe the changes, such as 'a marked increase' instead of 'a significant rise.'

Grammatical Range & Accuracy

The report demonstrates a good command of grammar, with a variety of sentence structures used. However, there are a few instances where grammatical accuracy could be improved. Pay close attention to subject-verb agreement and correct tense usage. For example, review the sentence 'Farm and industrial waste has been reduced considerably' to ensure the verb agrees with the compound subject. Also, double-check punctuation for clarity.
