Task Response

The report attempts to describe the changes in energy sources between 1980 and 1990, but it contains several inaccuracies and irrelevant comments. For example, it incorrectly states that hydroelectric power remained at 5% (it was 4% in 1980 and 5% in 1990), and it includes subjective opinions about the economy that are not part of the task. The report also lacks a clear overview and has some organizational issues. To improve, focus on objectively summarizing the main trends, such as the significant decrease in oil and the increase in coal and nuclear power, and avoid personal commentary. Ensure all data is accurately reported and structure the response with a clear introduction, overview, and detailed paragraphs.

Coherence & Cohesion

The report has a logical structure, but the flow is disrupted by frequent punctuation errors and run-on sentences. The message can be followed, but with effort. To improve, use clear paragraphing: one paragraph for the overview and one for detailed changes. Use cohesive devices (e.g., 'in contrast', 'similarly', 'overall') to link ideas smoothly. Avoid informal comments and ensure each sentence is complete and properly punctuated.

Lexical Resource

The vocabulary is basic and repetitive, with some inaccuracies (e.g., 'scources' for 'sources', 'increace' for 'increase', 'futher' for 'further'). There is some attempt at variation (e.g., 'decreased', 'increase', 'slight decrease'), but the range is limited. To improve, use more precise and varied terms (e.g., 'accounted for', 'constituted', 'experienced a rise', 'remained stable'). Ensure correct spelling and word forms to enhance lexical resource.

Grammatical Range & Accuracy

The report contains numerous grammatical errors, including missing punctuation, incorrect verb forms, and awkward phrasing. For example, 'like the OIL lack of reliance on it over time' is unclear, and 'this is dangerous for the economy' is an unsupported opinion. There are also run-on sentences and missing articles. To improve, focus on sentence structure, use a variety of complex sentences, and proofread for grammar and punctuation. Practice writing clear, concise sentences with correct subject-verb agreement.
