Band 4+: The diagram below shows the process of using water to produce electricity. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The report addresses the task by describing the main stages of the process, but it contains some inaccuracies and omissions. The overview is somewhat misleading as it states the process ends with rain, whereas the process actually continues through electricity generation and distribution. Additionally, the description of the later stages (turbine, electricity generation, and distribution) is incomplete and lacks clarity. To improve, ensure the overview accurately reflects the entire process, and include all key stages with clear, accurate descriptions. Also, avoid minor spelling errors (e.g., 'sunsequent', 'reservair') and use precise vocabulary for technical terms. The report falls short of the required 150 words.

The report has a clear overall structure with an introduction and an overview, but the body paragraph lacks logical progression and clear paragraphing. The sequence of steps is presented in a somewhat disjointed manner, and the use of cohesive devices is limited. To improve, organize the process into clear stages (e.g., evaporation, storage, generation, distribution) and use a range of linking words and phrases (e.g., 'subsequently', 'following this', 'once') to guide the reader smoothly through the process.

The vocabulary used is adequate for the task, with some appropriate terms such as 'evaporation', 'turbine', and 'valve'. However, there are several inaccuracies and awkward phrasings (e.g., 'the heat of sunlight is entered in the sea', 'the water pump to the reservair', 'it crossed through turbine') that detract from clarity. To improve, use more precise and natural vocabulary (e.g., 'sunlight heats the sea', 'water is pumped to the reservoir', 'passes through the turbine') and ensure correct spelling (e.g., 'reservoir', 'subsequent').

The report uses a limited range of grammatical structures, with a tendency to rely on simple sentences and passive constructions. There are some errors in verb tense and subject-verb agreement (e.g., 'the rain is started', 'the water pump', 'it crossed through'), and punctuation is sometimes incorrect. To improve, vary sentence structures (e.g., use complex sentences with subordinate clauses) and ensure consistent and accurate use of tenses (e.g., present simple passive for processes).
