Task Achievement / Task Response — Band 5.5
The response provides an overview of the recycling process, but it fails to meet the minimum word count requirement of 150 words, which significantly impacts the score. While you have identified the main stages of the process, the description is somewhat superficial. To improve, ensure you expand on the details of each stage rather than just listing them. For example, you could describe the physical transformation of the materials more precisely. Because the response is under-length, it does not fully develop the information provided in the diagram, leading to a lower band score.
Coherence and Cohesion — Band 6.5
The essay is organised into paragraphs, which helps the reader follow the sequence of events. You have used some cohesive devices such as 'In the first step', 'After that', and 'Following this' to link your ideas. However, the flow is occasionally mechanical, and some transitions feel repetitive. To reach a higher band, try to vary your linking phrases and ensure that the progression between sentences is smoother. The overall structure is logical, but the lack of depth in the content makes the cohesion feel somewhat basic.
Lexical Resource — Band 6.0
Your vocabulary is generally adequate for describing a process, using terms like 'recycling centre', 'compressed', and 'raw material'. However, there are several inaccuracies and awkward collocations, such as 'crushing into a water' (which is unclear) and 'dump trucks are come'. There is also a reliance on basic verbs. To improve, you should aim for more precise terminology related to industrial processes and ensure that your word choices are grammatically appropriate for the context.
Grammatical Range and Accuracy — Band 5.5
There are frequent grammatical errors throughout the text, including subject-verb agreement issues ('dump trucks are come', 'all the bottles compressed') and incorrect verb forms ('how plastic bottles are recycle'). The sentence structures are mostly simple, with limited attempts at complex sentences. Punctuation is also inconsistent, particularly with the use of commas. To improve, focus on mastering basic sentence construction and ensuring that your verbs agree with their subjects. Increasing the variety of your sentence structures will also help improve your score.
