The diagram shows us the construction of simple water filter and how it works to produce clean water.

Overall, it consists of two huge tanks, one of them is responsible for purifying water, and other one is for storing.

Focusing on the construction of the filter first, it is a huge tank with cap that opens. Additionally, it has three levels of sand, charcoal and gravel, which filters dirty water.

Furthermore, gravel is located on the bottom of the filler and long tube is connected to it which moves the filtered water to another tank where purified drinking water is stored. The tank for storing drinking water is the same size and has a cap on the top. Also, there is small fduice on the bottom of it to poor some water.

Task Response

The report identifies the main components of the water filter and describes the process. However, the description lacks detail and precision. The language is simple and repetitive. To improve, provide more specific details about the layers in the filter, the flow of water, and the function of each component. Also, vary your vocabulary and sentence structure to enhance clarity and coherence. The report falls short of the required 150 words.

Coherence & Cohesion

The report generally presents a clear overview of the water filter's construction and function. However, the organization could be improved for better flow. Consider using more varied cohesive devices to link ideas within and between paragraphs. For example, instead of repeatedly starting sentences with 'Furthermore' or 'Also,' try using more sophisticated transitions to indicate relationships between ideas.

Lexical Resource

The vocabulary is adequate for describing the diagram, but there's room for improvement. Using more precise and varied vocabulary could enhance the description. For example, instead of 'huge tanks,' consider using more descriptive terms like 'large containers' or 'cylindrical tanks.' Also, 'fduice' is not the correct term; the word you're looking for is likely 'faucet' or 'spigot.' Expanding your vocabulary related to technical processes and equipment would be beneficial. Boost vocabulary complexity to elevate the overall score.

Grammatical Range & Accuracy

The report contains several grammatical errors that affect clarity. For example, 'one of them is responsible for purifying water, and other one is for storing' should be 'one is responsible for purifying water, and the other is for storing.' Also, 'filler' should be 'filter,' and 'poor' should be 'pour.' Pay close attention to subject-verb agreement, article usage (a/an/the), and correct spelling. Reviewing basic grammar rules and proofreading carefully can help reduce these errors.
