The diagram shows the design of a modern landﬁll for household waste.

The process demonstrates the life cycle of a modern landfill for the household waste.There are four stages to design a modern landfill, beginning with construction and ending with closure.

At the first stages, people would dug a giant hole unto the ground, which called name "man- made hole". The hole is above the natural rock. Then, lots of thick layer clay are used to line on the hole.

After that is the layer of synthetic substance,which control some toxic chemicals such as acid,plastic… to reduce them. This stage should prevent the toxic substance from flying out of the pit. Some drainage pipes and drainage tanks are built to screen the trash or toxic waste liquids from the landfill.

Moreover, the landfill has been installed,which be filled with household waste. During the landfill, trash and waste liquid will be remove and run to the dip of pit, where the waste liquid should be keep into the ground and screen to become the gas.

Finally, the hole is hole. It would be covered with a layer of clay.When the liquid in the landfill degrades, the gases are emitted. It is a way to protect the environment without the pollution by trash.17:03/-strong/-heart:>:o:-((:-h

Errors and Improvements:

"would dug" -> "would dig"
Explanation: "Would dug" is incorrect grammar. "Would dig" is the appropriate past tense form of the verb "dig" in this context.
"which called name" -> "which is called"
Explanation: "Which called name" is grammatically incorrect. "Which is called" is the correct phrase to introduce the name of something.
"above the natural rock" -> "above the bedrock"
Explanation: "Natural rock" could refer to any rock formation. "Bedrock" specifically refers to the solid rock underlying loose deposits such as soil or alluvium, which is more accurate in this context.
"thick layer clay" -> "thick clay layer"
Explanation: Adjectives usually come before nouns in English. "Thick clay layer" follows this order and sounds more natural.
"the layer of synthetic substance" -> "a layer of synthetic material"
Explanation: "Substance" is too general. "Material" is more precise and commonly used in this context.
"control some toxic chemicals such as acid, plastic…" -> "to contain various toxic chemicals such as acids and plastics…"
Explanation: "Control" implies actively managing the chemicals, whereas "contain" is more appropriate in this context. Also, "acid" should be pluralized to "acids," and "plastic" should be pluralized to "plastics" for correctness.
"should prevent the toxic substance" -> "aims to prevent toxic substances"
Explanation: "Should prevent" lacks the assertiveness of intent conveyed by "aims to prevent." Also, "substance" should be pluralized to match the plural form of "toxic chemicals."
"Some drainage pipes and drainage tanks are built to screen the trash or toxic waste liquids from the landfill." -> "Drainage pipes and tanks are constructed to filter out solid waste and toxic liquids from the landfill."
Explanation: "Screen" implies merely separating, while "filter out" suggests removing impurities, which is more accurate here. Additionally, "solid waste" specifies the type of waste being filtered.
"Moreover, the landfill has been installed,which be filled with household waste." -> "Furthermore, the landfill is then filled with household waste."
Explanation: "Has been installed" is passive voice and less direct. Using "is then filled" in active voice enhances clarity and directness.
"During the landfill" -> "During the filling of the landfill"
Explanation: "During the landfill" is unclear and awkward. Clarifying that it refers to the process of filling the landfill with waste enhances understanding.
"trash and waste liquid will be remove" -> "trash and waste liquid will be removed"
Explanation: "Remove" should be in the past participle form "removed" to maintain grammatical consistency.
"the hole is hole" -> "the hole is filled"
Explanation: "Hole" is repeated unnecessarily. Replacing it with "filled" clarifies the intended meaning.
"be keep into the ground" -> "be kept within the ground"
Explanation: "Be keep" is incorrect grammar. "Be kept" is the correct form of the verb in passive voice.
"screen to become the gas" -> "filtered to produce gas"
Explanation: "Screen to become the gas" is unclear. "Filtered to produce gas" clarifies that the gas is a result of the filtration process.
"When the liquid in the landfill degrades, the gases are emitted." -> "As the liquids in the landfill degrade, gases are emitted."
Explanation: Using "as" instead of "when" establishes a clearer cause-and-effect relationship between liquid degradation and gas emission.
"It is a way to protect the environment without the pollution by trash." -> "This process safeguards the environment from pollution caused by waste."
Explanation: The original sentence is ambiguous and awkwardly constructed. Clarifying the subject and rephrasing for clarity improves readability and comprehension.

The diagram illustrates the process involved in the development of a contemporary landfill for household waste, encompassing four distinct stages from inception to closure.

Initially, excavation occurs to create a substantial cavity, referred to as a "man-made hole," positioned above the natural bedrock. This excavation is followed by the application of multiple layers of thick clay to line the cavity, serving as a foundational barrier.

Subsequently, a layer of synthetic material is applied, aimed at containing potentially harmful substances such as acids and plastics, thus mitigating the risk of environmental contamination. Additionally, the installation of drainage pipes and tanks facilitates the filtration of waste liquids and debris, further enhancing environmental safety measures.

The landfill is then filled with household waste, during which periodic removal of trash and waste liquids is conducted, directing them towards the base of the pit. Here, waste liquids are contained within the ground and undergo screening to extract gases, contributing to environmental protection efforts.

Ultimately, the cavity is sealed with a final layer of clay. As the liquids within the landfill degrade over time, gases are emitted, representing an environmentally responsible approach to waste management that minimizes pollution.

Overall, the depicted process outlines a comprehensive strategy for the management of household waste, emphasizing the importance of environmental preservation and sustainability.
