Task Response

The report covers the requirements of the task, providing a general overview and some specific details about the changes in energy sources between 1980 and 1990. However, there are some areas for improvement. The introduction and overall statement could be more concise and focused. The report could benefit from more precise language and a stronger focus on comparing and contrasting the data. For example, instead of saying "oil fell slightly," you could quantify the decrease more precisely. Also, avoid stating obvious facts like "As is shown by the chart that energy source in USA in 1980 was gradually than 1990."

Coherence & Cohesion

The report demonstrates some organization, but the flow of information is not always smooth. The 'overall' paragraph attempts to summarize but lacks precision and clarity. Transitions between sentences and paragraphs could be improved to enhance coherence. For example, the connection between the overall statement and the detailed analysis in the following paragraphs is weak. Paragraphing is acceptable but could be more effective in grouping related information.

Lexical Resource

The vocabulary used is generally adequate for the task, but there's a lack of precision and variety. Some phrases are used repetitively (e.g., 'in 1980,' 'in 1990'). There are instances of imprecise language ('a lot of,' 'less one,' 'gradually'). To improve, try to incorporate a wider range of vocabulary related to trends and proportions (e.g., 'constituted,' 'accounted for,' 'experienced a surge,' 'remained stable'). Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report contains several grammatical errors that affect clarity. Common errors include incorrect verb tense/form ('oil is used a lot of,' 'natural gas not changed'), incorrect use of articles ('the energy source,' 'in two seperate times'), and awkward phrasing ('As is shown by the chart that energy source in USA in 1980 was gradually than 1990'). Sentence structure is often simple and lacks complexity. To improve, focus on using a wider range of sentence structures and carefully proofread for grammatical errors.
