The diagram illustrates picture of how purify water is produced by utilising sustainable energy: solar power.

In brief, it is clear that there are lots of equipment, such as water tank, electricity, and much more are required to make it work. The main resource is sunlight from the sun, which gives a chance to clean water.

At the first step, sunlight goes straightforward to solar panel, which activates converter with electricity. Then, move to the underground water, there are thanks to the pump, people got unavailable to drink water, which will be cleaned soon.

In the following phase, water goes up to the water tank via long tube, where it purifies. The water tank is square formed, and has wood platform on which it rests; in addition, there are another tube, which allows drinking water to flow to the movable container. However, before it reaches the container, people should by-hand reverse the tap.

Task Response

The report attempts to describe the water purification system using solar power, but it contains inaccuracies and lacks clarity. The description of the process is not always logical or easy to follow. To improve, focus on providing a more accurate and detailed description of each stage of the process, using precise language and avoiding vague terms. Also, ensure that the sequence of events is clearly presented.

Coherence & Cohesion

The report lacks a clear overall structure and the progression of ideas is difficult to follow. The introduction is weak and doesn't effectively summarize the diagram. The body paragraphs lack clear topic sentences and the connections between sentences are often unclear. The use of cohesive devices is limited and sometimes inappropriate. Paragraphing needs improvement to better organize the information.

Lexical Resource

The vocabulary used is basic and lacks precision. There are instances of inaccurate word choice ('picture of how purify water') and overuse of simple words ('lots of equipment', 'much more'). The report would benefit from a wider range of vocabulary related to the process and equipment involved. Consider using more specific and technical terms where appropriate.

Grammatical Range & Accuracy

The report contains numerous grammatical errors, including incorrect verb tenses ('how purify water is produced'), subject-verb agreement issues ('much more are required'), and incorrect use of articles ('the diagram illustrates picture'). Sentence structure is often awkward and unclear. These errors significantly impede understanding. Focus on improving your understanding and application of basic grammar rules and sentence construction.
