¿Qué es el Skimming?
Skimming es una técnica de lectura rápida que consiste en leer un texto de forma superficial para capturar la idea central y la estructura general, sin detenerse en cada detalle. El objetivo es responder a la pregunta: "¿De qué trata este texto?"
Imagina que hojeas un periódico buscando noticias interesantes: no lees cada artículo completo, solo los títulos, los subtítulos y la primera línea de cada sección. Eso es skimming.

The Rise of Remote Work: Benefits, Challenges, and the Future
The COVID-19 pandemic fundamentally transformed the way millions of people around the world work, accelerating a shift toward remote work that had been building for years. Before 2020, only a small percentage of employees worked from home regularly. By mid-2020, however, surveys indicated that over 40% of the U.S. workforce had transitioned to fully remote positions. This dramatic shift forced companies, employees, and governments to reconsider traditional ideas about productivity, collaboration, and the workplace itself.
For many workers, remote work has brought significant benefits. Employees report higher levels of job satisfaction, reduced commuting stress, and greater flexibility to balance personal and professional responsibilities. Studies from Stanford University suggest that remote workers can be up to 13% more productive than their office-based counterparts. The elimination of the daily commute alone saves the average worker over 200 hours per year.
However, remote work is not without its challenges. Many employees struggle with feelings of isolation, difficulty separating work from personal life, and reduced opportunities for spontaneous collaboration. Managers face new pressures to maintain team cohesion and monitor performance without direct oversight. These issues are particularly pronounced for younger employees who miss the mentorship and social interactions that office environments naturally provide.
Companies are responding to these challenges by adopting hybrid work models that combine remote and in-office time. Technology firms like Google, Apple, and Microsoft have implemented flexible policies that allow employees to work remotely several days per week while maintaining dedicated office days for collaboration.
Looking ahead, experts predict that remote and hybrid work will become a permanent feature of the professional landscape. Organizations that adapt successfully will likely attract top talent, reduce overhead costs, and improve employee well-being. The future of work is not fully remote or fully in-office — it is flexible, technology-driven, and centered on results rather than physical presence.

Práctica 1: Artificial Intelligence in Education
Aplica el skimming. Lee primero el título, luego las primeras oraciones de cada párrafo y la conclusión. Luego responde las preguntas enfocadas en idea general y estructura.
Artificial Intelligence in Education: Transforming the Classroom
Artificial intelligence is rapidly reshaping education systems around the world, offering tools that personalize learning, automate administrative tasks, and provide students with unprecedented access to knowledge. What was once the realm of science fiction is now a daily reality in thousands of classrooms globally.
One of the most promising applications of AI in education is personalized learning. Platforms such as Khan Academy and Duolingo use AI algorithms to analyze individual student performance in real time, adjusting the difficulty and type of content to match each learner's pace and needs. Research suggests that students using AI-powered platforms improve their test scores by an average of 30% compared to those using traditional methods alone.
AI also plays a crucial role in reducing the administrative burden on teachers. Automated grading systems can evaluate multiple-choice tests, short written responses, and even essays in seconds, freeing teachers to focus on mentoring and creative instruction. In countries like China and South Korea, AI tools are already being used to provide instant feedback to students on homework and class assignments.
However, the integration of AI into education raises important ethical concerns. Critics argue that excessive reliance on algorithms can widen the digital divide, disadvantaging students from lower-income households who lack access to modern technology. Additionally, questions about data privacy — particularly regarding the collection of sensitive information about minors — have prompted calls for stronger regulatory frameworks.
Despite these challenges, most education experts agree that AI will become an indispensable part of modern schooling. The key, they argue, is not to replace human teachers but to empower them with intelligent tools that enhance their effectiveness. A future classroom will likely be a collaborative space where human creativity and artificial intelligence work side by side to unlock the full potential of every student.
Práctica 2: The Plastic Crisis

The Plastic Crisis: A Threat Without Borders
Plastic pollution has become one of the most urgent environmental crises of the 21st century, threatening ecosystems, human health, and the global economy in ways that scientists are only beginning to fully understand. Unlike other forms of waste, plastic does not biodegrade — it simply breaks down into smaller and smaller particles that persist in the environment for hundreds of years.
The scale of the problem is staggering. Globally, approximately 400 million metric tons of plastic are produced every year, yet only about 9% of all plastic ever manufactured has been recycled. The rest ends up in landfills, incinerated, or released into natural environments. Every year, between 8 and 12 million metric tons of plastic enter the world's oceans, where they form massive accumulations like the Great Pacific Garbage Patch, an area of floating debris estimated to be three times the size of France.
Marine life bears the heaviest burden of this crisis. Research has found plastic in the stomachs of over 700 species of marine animals, from sea turtles and seabirds to deep-sea fish that have never encountered a human being. Microplastics — fragments smaller than 5 millimeters — have been detected in fish tissue, shellfish, drinking water, and even in human blood and lung tissue, raising alarming questions about long-term health effects.
Governments and international organizations are responding with new policies and agreements. The European Union banned single-use plastics in 2021, and in 2023, representatives from over 170 countries began negotiating a global treaty to reduce plastic production at the source. However, experts warn that regulation alone is insufficient without a fundamental shift in consumer behavior and corporate manufacturing practices.
Solving the plastic crisis will require a systemic transformation — not simply better recycling, but a complete redesign of how societies produce, consume, and dispose of materials. Innovation in biodegradable alternatives, extended producer responsibility laws, and widespread public education are all essential ingredients in building a future where plastic no longer threatens the planet's living systems.
