Đề Tiếng Anh ôn thi tốt nghiệp THPT năm 2025- Mã đề thi THPT-12

(18) __________. Unlike classical computers that store information as bits representing 0 or 1, quantum computers employ qubits. Qubits, (19) __________, can exist in a combination of 0 and 1 simultaneously. This unique feature enables quantum computers to tackle problems that are practically impossible for even the most powerful classical computers.

Imagine a vast library containing billions of books, and you need to find one specific book. A classical computer would search each book sequentially, which could take an impractical amount of time. A quantum computer, on the other hand, could analyze all the books simultaneously, (20) __________. This ability to perform computations on multiple possibilities at once holds immense potential in fields like drug discovery, materials science, and artificial intelligence.

One compelling example is in cryptography, where quantum computers pose both a threat and an opportunity. Today's encryption algorithms, (21) __________, could be easily deciphered by powerful quantum computers in the future. This potential vulnerability has spurred the development of quantum-resistant cryptography, which relies on complex mathematical problems that even quantum computers are unlikely to crack.

(22) __________. Major technology companies and research institutions are investing heavily in this transformative technology, driven by its promise to revolutionize various industries. As quantum computers become more powerful and accessible, we can expect groundbreaking advancements in medicine, materials science, artificial intelligence, and beyond, ushering in a new era of technological innovation.

The development of green technologies is an essential component in addressing the world's pressing environmental challenges. These technologies, aimed at reducing human impact on the planet, encompass a wide range of innovations, from renewable energy sources like solar and wind power to electric vehicles and sustainable agricultural practices. The driving force behind this development is the growing awareness of climate change and its potential consequences, prompting governments, businesses, and individuals to seek ways to minimize their environmental footprint.

A key aspect of green technology development is its focus on resource efficiency. This means using fewer resources to achieve the same or better results, reducing waste and pollution in the process. For example, advancements in LED lighting technology have led to light bulbs that consume significantly less energy than traditional incandescent bulbs while lasting much longer. This, in turn, reduces the demand for electricity and the associated greenhouse gas emissions from power plants.

Furthermore, green technologies are fostering a transition to a circular economy. This model emphasizes reusing and recycling materials as much as possible, minimizing waste and promoting sustainability. Innovative recycling techniques are being developed to recover valuable resources from electronic waste, reducing the need for mining and its environmental impact. Similarly, companies are exploring new ways to use recycled plastics and other materials in manufacturing, further reducing reliance on virgin resources.

The ultimate goal of green technology development is to create a more sustainable future for generations to come. By reducing pollution, conserving resources, and mitigating climate change, these technologies offer a pathway towards a cleaner, healthier, and more equitable world. As research and innovation continue, we can expect to see even more groundbreaking green technologies emerge, offering hope for a brighter future for our planet.

[I] Water scarcity, affecting over 40% of the global population, is rapidly becoming one of the most pressing challenges of our time. [II] Population growth, industrial expansion, and unsustainable agricultural practices all contribute to this growing crisis. [III] Regions already experiencing water stress, such as parts of Africa, the Middle East, and South Asia, are expected to face even greater difficulties in the coming decades, potentially leading to conflicts over dwindling resources. [IV]

Climate change, as mentioned above, has a profound impact on water availability. It intensifies the hydrological cycle, leading to more extreme weather events like floods and droughts. These events disrupt established water management systems and can contaminate existing freshwater sources. Furthermore, rising sea levels threaten coastal aquifers, pushing saltwater further inland and contaminating vital sources of drinking water for millions of people. The interconnectedness of climate change and water scarcity underscores the urgency of addressing both issues simultaneously.

Implementing water-efficient technologies and practices is crucial for mitigating water scarcity. In agriculture, drip irrigation systems and drought-resistant crops can significantly reduce water consumption. Industries can adopt recycling and water reuse systems, minimizing their freshwater intake and reducing wastewater discharge. At the household level, promoting water conservation through education campaigns and incentives can encourage responsible water use. Installing low-flow showerheads, fixing leaky faucets, and using water-wise appliances are all simple yet effective ways to reduce individual water footprints.

Global cooperation and innovation are essential to address the complex challenge of water scarcity. Investing in research and development of desalination technologies can provide alternative sources of freshwater, particularly for coastal communities. International agreements on transboundary water management can foster collaboration and prevent conflicts over shared water resources. By combining technological advancements with sustainable water management strategies, we can strive towards a water-secure future for all.
