Model Answers with Scoring Breakdowns

Band 6.0 Answer

Model Answer:

The ocean is very important for the world, but it is becoming more polluted. Some people say that technology can help with this problem, but others disagree. I think that technology can help, but it also causes more pollution.

One advantage of technology is that it can clean up the ocean. For example, there are machines that can collect plastic from the water. This is good because plastic is very bad for marine life. Another advantage is that technology can help us find new ways to recycle materials. This means that we can use less new material and reduce waste.

However, technology also has disadvantages. One problem is that making new technology often creates pollution. For example, factories that make machines produce a lot of waste. Another problem is that some technologies are not very effective. For example, some machines that collect plastic do not work very well and can harm marine life.

In conclusion, technology can help with ocean pollution, but it also causes more pollution. We need to be careful about how we use technology to protect the ocean.

Scoring Breakdown:

• Task Response (TR): 5.0 - Presents a position but does not extend or support ideas sufficiently
• Coherence and Cohesion (CC): 6.0 - Uses some cohesive devices but often lacks logical sequencing
• Lexical Resource (LR): 6.0 - Uses some less common vocabulary but makes some errors in word choice
• Grammatical Range and Accuracy (GRA): 6.0 - Uses a mix of simple and complex sentence forms but makes frequent grammatical errors

Band 7.0 Answer

Model Answer:

The issue of ocean pollution has become a pressing concern in recent years. While some argue that technological advancements offer solutions to this problem, others contend that these developments exacerbate the situation. I believe that although technology provides some benefits, its drawbacks often outweigh them.

On the one hand, technology offers several advantages in combating ocean pollution. For instance, advanced filtration systems can remove contaminants from water, significantly improving water quality. Additionally, satellite technology enables us to monitor and track pollution sources, allowing for more effective intervention. Furthermore, innovative recycling technologies can convert waste into useful resources, reducing the amount of waste that ends up in the ocean.

However, the disadvantages of technological advancements are equally significant. The production of new technologies often involves the use of hazardous materials, which can contribute to pollution. Moreover, the disposal of outdated technology can lead to electronic waste, which is difficult to manage and can release harmful substances into the environment. Additionally, the high cost of implementing these technologies can be a barrier for many countries, limiting their widespread adoption.

In conclusion, while technology offers some solutions to ocean pollution, its drawbacks are substantial. It is crucial that we carefully consider the environmental impact of new technologies and strive for more sustainable solutions.

Scoring Breakdown:

• Task Response (TR): 7.0 - Presents a clear position throughout and extends and supports ideas, but some ideas are not fully developed
• Coherence and Cohesion (CC): 7.0 - Uses cohesive devices effectively but there may be some unclear referencing
• Lexical Resource (LR): 7.0 - Uses a sufficient range of vocabulary to convey ideas precisely but may make some errors in word choice
• Grammatical Range and Accuracy (GRA): 7.0 - Uses a mix of simple and complex sentence forms but may make some grammatical errors

Band 8.0 Answer

Model Answer:

The escalating problem of ocean pollution has sparked intense debate regarding the role of technological advancements. Proponents argue that these innovations offer viable solutions, while critics contend that they often exacerbate the problem. In my view, while technology presents some advantages, its drawbacks are more pronounced and warrant greater attention.

Advocates of technological solutions highlight several compelling benefits. For instance, advanced desalination plants can convert seawater into fresh water, alleviating pressure on natural water sources. Furthermore, the development of biodegradable materials has reduced the environmental impact of marine litter. Additionally, remote sensing technologies enable real-time monitoring of ocean conditions, facilitating prompt intervention in pollution incidents.

However, the disadvantages of technological advancements are equally compelling. The extraction of rare earth metals, essential for many technologies, often involves environmentally destructive mining practices. Additionally, the energy consumption of these technologies can be substantial, contributing to greenhouse gas emissions. Moreover, the rapid obsolescence of technology leads to a surge in electronic waste, which is challenging to manage and can release toxic substances into the environment.

In conclusion, while technological advancements offer some solutions to ocean pollution, their drawbacks are significant and often overlooked. It is imperative that we adopt a more holistic approach, considering the environmental impact of new technologies and promoting sustainable practices.

Scoring Breakdown:

• Task Response (TR): 8.0 - Presents a clear position throughout and extends and supports ideas with relevant examples
• Coherence and Cohesion (CC): 8.0 - Uses cohesive devices effectively and presents ideas in a logical sequence
• Lexical Resource (LR): 8.0 - Uses a wide range of vocabulary to convey ideas precisely and appropriately
• Grammatical Range and Accuracy (GRA): 8.0 - Uses a wide range of complex sentence forms but may make some grammatical errors

Band 9.0 Answer

Model Answer:

The pervasive issue of ocean pollution has ignited a contentious debate regarding the efficacy of technological interventions. While proponents extol the virtues of these innovations, detractors highlight their deleterious consequences. In my view, the disadvantages of technological advancements in mitigating ocean pollution far outweigh their advantages, necessitating a more nuanced approach.

Proponents of technological solutions often cite the development of advanced filtration systems, which can effectively remove contaminants from water. Moreover, the advent of biodegradable materials has significantly reduced the environmental impact of marine litter. Additionally, the implementation of remote sensing technologies has enabled real-time monitoring of ocean conditions, facilitating prompt intervention in pollution incidents. Furthermore, the integration of artificial intelligence in waste management systems has optimized recycling processes, minimizing waste generation.

However, the disadvantages of technological advancements are equally compelling. The extraction of rare earth metals, crucial for many technologies, often involves environmentally destructive mining practices. Additionally, the energy consumption of these technologies can be substantial, contributing to greenhouse gas emissions. Moreover, the rapid obsolescence of technology leads to a surge in electronic waste, which is challenging to manage and can release toxic substances into the environment. Furthermore, the high cost of implementing these technologies can be a barrier for many countries, limiting their widespread adoption.

In conclusion, while technological advancements offer some solutions to ocean pollution, their drawbacks are significant and often overlooked. It is imperative that we adopt a more holistic approach, considering the environmental impact of new technologies and promoting sustainable practices. This may involve investing in renewable energy sources, implementing stricter regulations on waste management, and fostering international cooperation to address this global issue.
