Band 5+: The process shows the design of a modern landfill for household waste. Write at least 150 words.

The report addresses the task and covers the main stages of the landfill process, but it contains some inaccuracies and omissions. For instance, the order of construction steps is slightly confused (clay is mentioned before synthetic lining, whereas the visual description indicates synthetic lining comes first), and the closure stage is not clearly separated from the use stage. Additionally, the report omits the drainage tank's specific role and the gas venting system's purpose. The language is generally clear, but there are grammatical errors and awkward phrasing (e.g., 'The design illustrate', 'hole digged', 'insurt gases'). To improve, ensure the stages are logically sequenced, include all key features, and proofread for grammatical accuracy. The report falls short of the required 150 words.

The report has a clear overall structure with an introduction and a description of the stages, but the progression of ideas is sometimes unclear. The description of the construction and use stages is somewhat muddled, and the closure stage is not clearly separated. The use of cohesive devices is limited, and the report lacks clear paragraphing. To improve, organize the description into distinct paragraphs for each stage (construction, use, closure) and use a range of linking words and phrases to guide the reader through the process.

The vocabulary is adequate for the task, but there are several inaccuracies and limited range. Words like 'digged', 'linning', 'insurt', and 'natutal' are misspelled, and phrases such as 'a layers of clay' and 'in botton' are not natural. The report would benefit from a wider range of precise vocabulary related to the process (e.g., 'excavated', 'synthetic membrane', 'leachate', 'ventilation pipes') and more sophisticated phrasing. Ensure correct spelling and word forms to improve lexical accuracy. Boost vocabulary complexity to elevate the overall score.

The report contains a number of grammatical errors that affect clarity, including subject-verb agreement ('The design illustrate'), incorrect verb forms ('hole digged'), and inconsistent tense usage (e.g., 'will be placed' vs. 'were placed'). There are also issues with articles and prepositions (e.g., 'a layers', 'on the top of'). To improve, use a wider range of sentence structures, ensure subject-verb agreement, and maintain consistent tense throughout. Proofread to eliminate basic errors and improve overall grammatical accuracy.
