Band 5+: The diagram below illustrates the process by which ceramic floor tiles are manufactured.

The report adequately covers the main stages of the ceramic tile manufacturing process, from clay extraction to firing in a kiln. The overall structure is logical, with an introduction, an overview, and a sequential description. However, there are some omissions and lapses: the overview could be more precise (e.g., mentioning the transformation from raw material to finished product), and some stages are described vaguely (e.g., 'mixing the water' instead of 'mixing with water', and 'put and waited for drying' could be clearer). Additionally, there are minor grammatical errors and informal phrasing (e.g., 'in the field', 'little pool', 'belt' without specifying conveyor). To improve, ensure each stage is clearly and accurately described, and use more precise vocabulary related to manufacturing processes. The report falls short of the required 150 words.

The report presents the stages in a logical sequence, but the flow is disrupted by unclear phrasing and missing cohesive devices. For example, the transition from 'screened before mixing the water' to 'the mixture is pressed' could be smoother. The use of 'in the following Stage' is awkward and inconsistent with the rest of the text. The final sentence is run-on and lacks clear punctuation, making it harder to follow. To improve, use a wider range of linking words (e.g., 'subsequently', 'following this', 'once') and ensure each sentence is clearly separated and logically connected.

The vocabulary is adequate for the task, with some appropriate terms like 'extracted', 'crushed', 'screened', 'pressed', 'dried', 'glazed', and 'fired'. However, there is limited range and some imprecise word choices (e.g., 'big vehicles' instead of 'excavators', 'little pool' instead of 'mixing vat', 'belt' instead of 'conveyor'). The phrase 'material for producing ceramic which called clay' is awkward and could be rephrased more naturally. To improve, use more specific and varied vocabulary related to manufacturing processes, and ensure word forms are correct (e.g., 'turned to tile' should be 'turned into tiles'). Boost vocabulary complexity to elevate the overall score.

The report contains several grammatical errors that affect clarity. For instance, 'which called clay' should be 'which is called clay', and 'mixing the water' should be 'mixing with water'. There are also issues with article usage (e.g., 'in the mine' should be 'in a mine') and subject-verb agreement (e.g., 'tiles are put and waited' is awkward). The sentence 'At the end of the process, the tiles are fired in a kiln and after this, they are ready for usage, the whole process ends' is a run-on and should be split into separate sentences. To improve, focus on using a wider range of sentence structures, ensuring subject-verb agreement, and proofreading for punctuation and article errors.
