Task Response

The report identifies the main components of the central heating system, but the description lacks clarity and organization. There are some inaccuracies and a tendency to describe the process rather than summarize the main features. To improve, focus on providing a more structured overview, using precise language, and ensuring accurate descriptions of the system's operation.

Coherence & Cohesion

The report attempts to describe the central heating system, but the organization is somewhat unclear. The introduction could be more focused on summarizing the diagram's main features. The body paragraphs lack clear topic sentences and transitions, making it difficult to follow the flow of information. Consider using more precise language to describe the sequence of processes and the relationships between components. Improve paragraphing by grouping related ideas together and using transitional phrases to connect them.

Lexical Resource

The vocabulary used is basic and lacks the precision needed to accurately describe the diagram. There are instances of imprecise word choice (e.g., "magic of warmth temperate"). Expand your vocabulary related to technical processes and components. Use more specific terms to describe the parts of the heating system and their functions. For example, instead of 'pipes for transport,' use 'pipes for circulation' or 'distribution pipes.' Consider using synonyms to avoid repetition and demonstrate a wider range of vocabulary.

Grammatical Range & Accuracy

The report contains numerous grammatical errors that affect clarity. Errors include incorrect verb tenses, subject-verb agreement issues, and awkward phrasing. For example, "if be exactly to the water cistern" and "the whole water circulates and still be hot" contain grammatical errors. Focus on using correct sentence structures and verb tenses. Proofread carefully to identify and correct errors in grammar and punctuation. Vary sentence structure to improve readability.
