The diagrams shows the design of a modern landfill for household waste.
Summarize the information by selecting and reporting the main features, and make comparisons where relevant.

The image gives information about the compositions and structures of a modern landfill that each household unit uses in their daily lives to treat their waste. The entire process comprises the stages of construction, using it to treat waste, and the final closure for environmental purposes.
The first stage begins with the creation of a vessel that would contain the waste of household units discharged later on. Specifically, a shallow pit that is shaped as a prism is embedded into the ground, which transcends a layer of natural rock. In the second step, the pit is covered with clay and a layer of synthetic material, which would help contain the waste and prevent leakage into the environment. A system of drainage pipes is implemented at the bottom of the tank, which draws water from the waste and then contains it into the vessel below.
Regarding the step of actual usage, the hole is filled with household waste. As the waste is decomposed, it releases a form of liquid that would be contained in the pre-created tank. After the hole exceeds its maximum capacity, it would be sealed away from the environment with another layer of clay being put on top of it. Another pipe system would lead the natural gas released from the waste away into a designated area.

Explanation: "Discharges" is the correct term for releasing or discharging fluids, which is more precise in this context.
"the hole is filled with household waste" -> "the pit is filled with household waste"
Explanation: Consistency in terminology is important; using "pit" instead of "hole" maintains the earlier description, ensuring clarity and precision.
"it releases a form of liquid" -> "it produces a liquid"
Explanation: "Produces" is a more direct and formal term than "releases," which is slightly vague and less precise in this context.
"would be contained in the pre-created tank" -> "is contained in the pre-created tank"
Explanation: "Is" corrects the tense to match the ongoing process described, improving the accuracy and formality of the statement.
"it would be sealed away from the environment" -> "it is sealed away from the environment"
Explanation: "Is" corrects the tense to reflect the current action, aligning with the ongoing process of sealing the waste.
"with another layer of clay being put on top of it" -> "with an additional layer of clay applied on top"
Explanation: "Applied" is more formal and precise than "put," and "an additional layer" is clearer than "another layer," enhancing the academic tone.
"Another pipe system would lead the natural gas" -> "Another pipe system leads the natural gas"
Explanation: "Leads" corrects the tense to match the ongoing action, aligning with the description of the process.

Band điểm Task Achivement ước lượng: 6

Band Score: 6

Explanation: The essay provides an overview of the stages of a modern landfill, but it does not fully satisfy all the requirements of the task. The essay does not present a clear overview of the main trends, differences, or stages. It also does not adequately highlight the key features of the landfill design. For example, the essay mentions the use of clay and synthetic materials, but it does not explain how these materials contribute to the overall design of the landfill.

How to improve: The essay could be improved by providing a clearer overview of the main stages of the landfill design. The essay could also be improved by highlighting the key features of the design, such as the use of clay and synthetic materials, and explaining how these features contribute to the overall design. The essay should also make comparisons between the different stages of the landfill design. For example, the essay could compare the construction stage to the closure stage.

Band điểm Coherence & Cohesion ước lượng: 6

Band Score: 6.0
Explanation: The essay arranges information and ideas coherently, providing a clear overall progression from the construction of the landfill to its usage and final closure. However, while cohesive devices are used effectively, there are instances where the cohesion between sentences could be improved, leading to some mechanical flow. The paragraphing is present but could be more logically structured to enhance clarity and organization. For example, separating the construction details from the usage and closure stages into distinct paragraphs would improve readability.

How to improve:

Enhance Paragraph Structure: Clearly separate different stages of the landfill process into distinct paragraphs. For instance, one paragraph could focus on construction, another on usage, and a third on closure.
Improve Cohesion: Use a wider range of cohesive devices to connect ideas more fluidly. For example, instead of starting sentences with "Regarding the step of actual usage," consider using phrases like "In terms of usage" or "During the operational phase."
Clarify Referencing: Ensure that all references to previous ideas are clear. For example, when mentioning "the hole," specify that it refers to the landfill pit to avoid ambiguity.
Avoid Repetition: Vary language and sentence structure to prevent redundancy, particularly in describing the landfill’s components and processes.

Band điểm Lexical Resource ước lượng: 6

Band Score: 6.0
Explanation: The essay demonstrates an adequate range of vocabulary relevant to the topic of modern landfills. It attempts to use some less common vocabulary, such as "compositions," "transcends," and "decomposed," but there are instances of inaccuracy and awkward phrasing that detract from clarity. Additionally, there are some errors in word formation, such as "a form of liquid that would be contained in the pre-created tank," which could be expressed more clearly. While the vocabulary used does not impede communication, it lacks the sophistication and precision expected at higher band levels.
How to improve: To enhance the lexical resource score, the writer should focus on using a broader range of precise vocabulary and ensuring correct collocations. Incorporating more sophisticated lexical items and varying sentence structures would also help. Additionally, proofreading for spelling and word formation errors would improve clarity and overall effectiveness.

Band điểm Grammatical Range & Accuracy ước lượng: 6

Band Score: 6.0
Explanation: The essay demonstrates a mix of simple and complex sentence forms, which is characteristic of a Band 6. While there are some attempts at complex structures, the overall grammatical accuracy is inconsistent, with several errors present. These errors do not significantly impede communication, but they are noticeable enough to affect the overall impression of grammatical control. For instance, phrases like "the compositions and structures of a modern landfill that each household unit uses in their daily lives to treat their waste" are somewhat convoluted and could be simplified for clarity. Additionally, there are instances of awkward phrasing and punctuation issues, such as "which transcends a layer of natural rock," which may confuse readers.

How to improve:
To enhance the grammatical range and accuracy, the writer should focus on the following areas:

Sentence Structure: Aim for clearer and more concise sentence constructions. Avoid overly complex or convoluted phrases that may confuse readers.
Error Reduction: Proofread the essay to identify and correct grammatical errors and awkward phrasing. This includes ensuring subject-verb agreement and proper use of articles.
Variety in Sentence Forms: Continue to incorporate a variety of sentence structures, but ensure that complex sentences are grammatically correct and enhance the clarity of the writing.
Punctuation: Pay attention to punctuation rules to avoid errors that could disrupt the flow of the essay. Proper use of commas and periods can improve readability.

By focusing on these areas, the writer can work towards achieving a higher band score in the Grammatical Range and Accuracy criteria.

The image provides information about the composition and structure of a modern landfill that each household unit uses in their daily lives to manage their waste. The entire process comprises the stages of construction, usage for waste treatment, and final closure for environmental purposes.

The first stage begins with the creation of a vessel designed to contain the waste discharged from household units. Specifically, a shallow pit shaped like a prism is embedded into the ground, which extends through a layer of natural rock. In the second step, the pit is covered with clay and a layer of synthetic material, which helps contain the waste and prevent leakage into the environment. A system of drainage pipes is installed at the bottom of the tank, which draws water from the waste and directs it into the vessel below.

During the actual usage phase, the pit is filled with household waste. As the waste decomposes, it releases a liquid that is contained in the pre-created tank. Once the pit reaches its maximum capacity, it is sealed off from the environment with another layer of clay placed on top. An additional pipe system directs the natural gas released from the waste to a designated area.
