📝 Model Essay: International Cooperation on Global Issues

Introduction: In today’s interconnected world, many pressing issues transcend national borders and require collaborative efforts for effective resolution. I strongly agree that international cooperation is essential in addressing these urgent problems, as it brings together diverse resources, expertise, and perspectives that no single nation can provide alone.

Body Paragraph 1: Firstly, environmental challenges such as climate change, deforestation, and pollution are quintessential examples of problems that necessitate global cooperation. The atmosphere and oceans do not adhere to political boundaries, and actions taken by one country can have far-reaching impacts on others. International agreements like the Paris Agreement exemplify how countries can unite to set common goals and share responsibilities in mitigating environmental damage. Without such cooperation, efforts to combat climate change would be fragmented and less effective.

Body Paragraph 2: Secondly, global health crises, such as the COVID-19 pandemic, highlight the importance of international collaboration. The rapid spread of infectious diseases requires a coordinated response to develop and distribute vaccines, share critical information, and implement public health measures. Organizations like the World Health Organization (WHO) play a pivotal role in facilitating this cooperation, ensuring that resources are allocated where they are most needed and that best practices are shared globally.

Body Paragraph 3: Moreover, economic issues such as trade imbalances, financial crises, and poverty also benefit from international cooperation. Multilateral institutions like the International Monetary Fund (IMF) and the World Bank provide platforms for countries to work together to stabilize economies, provide financial assistance, and promote sustainable development. These collaborative efforts help to create a more stable and prosperous global economy.

Conclusion: In conclusion, the complexity and scale of many of today’s urgent problems make international cooperation not just beneficial but essential. By working together, countries can pool their resources, share knowledge, and implement comprehensive solutions that are more effective than isolated efforts. Therefore, fostering international cooperation should be a priority in addressing the critical challenges of our time.

📊 Body Paragraph 1 Topic Sentence Analysis

Topic Sentence: “Firstly, environmental challenges such as climate change, deforestation, and pollution are quintessential examples of problems that necessitate global cooperation.”

What Makes It Effective:

• Clear sequencing marker: “Firstly” signals this is the beginning of a structured argument
• Specific examples: Immediately provides concrete issues (climate change, deforestation, pollution)
• Evaluative language: “Quintessential examples” shows analytical thinking
• Direct connection: Clearly links to “problems” and “global cooperation” from the question
• Advanced vocabulary: “Necessitate” demonstrates sophisticated language appropriate for the IELTS writing test

Our writing exercises ielts often include practicing this type of detailed topic sentence that demonstrates both clear structure and sophisticated vocabulary. Sample sentences like this appear frequently in IELTS writing examples from high-scoring essays, and our ielts writing evaluation online service specifically analyzes these elements.

📊 Body Paragraph 2 Topic Sentence Analysis

Topic Sentence: “Secondly, global health crises, such as the COVID-19 pandemic, highlight the importance of international collaboration.”

What Makes It Effective:

• Sequential transition: “Secondly” maintains the essay’s logical progression
• Relevant current example: The COVID-19 pandemic provides a timely and relatable reference
• Focused theme: “Global health crises” introduces a new category of international problems
• Verb choice: “Highlight” effectively connects the example to the essay’s main argument
• Parallel structure: Maintains similar construction to the first topic sentence for cohesion

This approach is featured in our ielts writing evaluation online tool to show how consistent structure combined with varied examples creates a cohesive yet interesting essay. Our ielts writing evaluation online would give this topic sentence high marks for clarity and relevance, making it an excellent example for IELTS writing practice.

📊 Body Paragraph 3 Topic Sentence Analysis

Topic Sentence: “Moreover, economic issues such as trade imbalances, financial crises, and poverty also benefit from international cooperation.”

What Makes It Effective:

• Advanced transition: “Moreover” signals progression beyond simple enumeration
• New category introduction: “Economic issues” adds a third dimension to the argument
• Multiple examples: Provides three different economic challenges (trade, finance, poverty)
• Positive framing: “Benefit from” shows constructive impact of cooperation
• Echoes question: Reinforces “international cooperation” from the original prompt

This demonstrates advanced IELTS writing strategies that help develop a comprehensive response to the question through varied but thematically linked topic sentences—a skill developed through regular writing exercises ielts preparation and refined through our ielts writing evaluation online feedback system.

Model Introduction 1: International Cooperation Question

“In an increasingly interconnected global landscape, nations face unprecedented challenges that transcend geographical boundaries. Many argue that international cooperation has become not merely beneficial but essential for addressing urgent problems such as climate change, pandemic diseases, and economic instability. This essay strongly supports the view that while national sovereignty remains important, effective solutions to today’s most pressing issues require collaborative approaches that leverage collective expertise, resources, and political will.”

Model Introduction 2: Space Exploration Question

“Space exploration represents one of humanity’s greatest scientific endeavors, yet opinions differ on whether such ambitious projects should be primarily national achievements or international collaborations. Some advocate for robust national space programs that serve strategic interests and national pride, while others emphasize the benefits of pooling resources and expertise through international partnerships. This essay will examine both perspectives before arguing that a hybrid approach offers the most pragmatic pathway to significant space achievements.”

Our ielts writing evaluation online consistently rates these introductions highly for clarity and sophistication, making them excellent models for IELTS writing practice.
