Task Response

The report identifies the main components of the heating system and describes the flow of water and heat through the house. However, the description lacks detail and clarity in places. To improve, focus on providing a more structured and detailed explanation of the process, and ensure accurate use of vocabulary related to heating systems.

Coherence & Cohesion

The report generally presents a clear overview of the heating system. However, the organization could be improved for better flow. Consider using more explicit transition words and phrases to guide the reader through the process. For example, phrases like 'Firstly,' 'Secondly,' 'Following this,' or 'Finally' could enhance the structure. Paragraphing is adequate but could be refined to separate distinct stages of the process more clearly.

Lexical Resource

The vocabulary used is generally appropriate for the task, but there's room for improvement in terms of precision and variety. For instance, instead of repeatedly using 'the water,' you could use terms like 'heated water' or 'hot water supply' to add nuance. Explore synonyms for common words to demonstrate a wider lexical range. Also, ensure correct spelling throughout the report. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report contains grammatical errors that affect clarity. Focus on subject-verb agreement, correct tense usage, and proper article usage (a/an/the). For example, 'the cold water gets heated into furnace' should be revised for accuracy. Pay attention to sentence structure to avoid run-on sentences and ensure each sentence conveys a clear idea. Proofreading carefully for these errors will improve the overall grammatical accuracy.
