Task Response

The report addresses the main components of the task and identifies the key energy sources. However, there are significant issues with data accuracy and logical consistency. For instance, the report states that oil 'increased modestly' in the summary, whereas the data shows it actually decreased from 42% to 33%. Additionally, there is a contradiction where the report describes oil as the 'first highest' in 1980 but then says it was 'ranked the second' in 1980 (likely meaning 1990) while noting a decrease. To improve, ensure that the trends described (increase vs. decrease) strictly match the numerical data provided, and focus on improving grammatical accuracy to ensure the comparisons are clear. The report falls short of the required 150 words.

Coherence & Cohesion

The organization of the report is somewhat logical, but the progression of ideas is hindered by significant grammatical errors and awkward phrasing. While you attempt to group information, the transitions between sentences are often abrupt or confusing. To improve, focus on using cohesive devices (e.g., 'In contrast,' 'Furthermore,' 'Regarding...') more effectively and ensure that each sentence flows logically into the next. Avoid using 'To sum up' for a Task 1 report; instead, use an overview paragraph at the beginning to summarize the main trends.

Lexical Resource

The vocabulary used is limited and contains several spelling errors (e.g., 'fist hrighest', 'whearas', 'repectively', 'exept') and incorrect word forms (e.g., 'five crucial energy' instead of 'energy sources'). There is also some misuse of words, such as using 'who' to refer to oil. To improve, work on building a bank of academic synonyms for describing trends (e.g., 'fluctuated', 'remained stable', 'declined') and ensure that nouns and adjectives are used in their correct forms. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

Grammatical errors are frequent and often impede the reader's understanding. There are issues with subject-verb agreement ('This pie charts'), tense usage ('oil over taken'), and sentence structure (run-on sentences and fragments). For example, the sentence describing oil in 1980 and 1990 is structurally confused. To improve, practice constructing simple and complex sentences with correct tense consistency. Pay close attention to articles (a, an, the) and prepositions (e.g., 'consisted of' rather than 'consisted at').
