Task Achievement / Task Response — Band 4.0

The response attempts to describe the recycling process but fails to provide a clear overview or highlight the main features effectively. The description is fragmented into a list-like format, focusing on individual steps rather than synthesizing the information. The content is often inaccurate or overly simplistic, such as referring to a 'dust jeep' or 'human who throw the plastic bottle'. The response lacks the analytical tone required for an Academic Task 1 report. To improve, you should group the stages logically (e.g., collection, processing, and manufacturing) and provide a concise summary of the overall process in the introduction.

Coherence and Cohesion — Band 4.0

The essay lacks logical progression and effective paragraphing. While you have attempted to number the processes, this is a mechanical approach that does not create a cohesive flow. There is a lack of linking words or transition phrases to connect the stages of the process. The sentences are often disjointed, making it difficult for the reader to follow the sequence of events. To improve, use cohesive devices such as 'subsequently', 'following this', or 'once the bottles are collected' to link your ideas and ensure the text reads as a unified report rather than a list of steps.

Lexical Resource — Band 4.0

The vocabulary is very limited and repetitive, relying heavily on basic words like 'process', 'things', and 'making'. There are significant issues with word choice and collocation, such as 'dust jeep' instead of 'collection vehicle' and 'human who throw' instead of 'consumers dispose of'. The lack of technical terminology related to recycling (e.g., 'sorting', 'shredding', 'granulation') prevents the response from achieving a higher score. You need to expand your vocabulary to include more precise, topic-specific terms and avoid informal or inaccurate phrasing.

Grammatical Range and Accuracy — Band 4.0

The grammar is consistently weak, with frequent errors in sentence structure, subject-verb agreement, and article usage. For example, 'human who throw the plastic bottle' should be 'humans who throw plastic bottles', and 'picture show crushing' should be 'the picture shows the crushing of'. There is a lack of complex sentence structures, and the existing sentences are often grammatically incomplete or run-on. To improve, focus on mastering basic sentence construction, including correct verb tenses and pluralization, before attempting more complex structures.
