Wind is a form of solar energy that results (21) __________ the uneven heating of the atmosphere by the sun. Essentially, wind is just air in motion. This movement creates kinetic energy, which humans have used for centuries. Because the wind will always blow as long as the sun shines, it is a powerful and renewable resource. This means that we can use it to generate power without worrying about it running out, unlike fossil fuels like coal and oil.

To capture wind energy, we use special machines called wind turbines. A typical wind turbine has a very tall tower with large blades, (22) __________ look like propellers on a plane. These blades are carefully designed to capture the maximum amount of wind energy. The size and shape of the blades can vary depending on the location and the average wind speed, but they all serve the same fundamental purpose.

The process of generating electricity from wind is quite straightforward. When the wind blows, it pushes against the blades, causing them to spin. The kinetic energy from the wind is transferred to a central rotor. This rotor is connected through a series of gears to a generator. This rotation powers a generator to create electricity, which is then sent out to power homes and businesses. It's a highly effective process.

One of the greatest advantages of wind energy is that it is a clean fuel source. It doesn't pollute the air like power plants that rely on burning fossil fuels. (23) __________, it is a domestic source of energy, which can increase a country's energy security. Large groups of turbines, known as wind farms, are often built in windy locations like coastlines or open plains. (24) __________ turbine can generate enough electricity for hundreds of homes.

The main benefit of wind energy is that it is a renewable resource that produces no greenhouse gas emissions during operation. As the world continues to seek cleaner energy solutions to combat climate change, wind power will undoubtedly play a crucial role in our sustainable future, helping to create a healthier planet for generations to come.

Every culture possesses unique social norms, dictating how individuals interact, especially across age groups. While some traditional customs evolve, others remain deeply ingrained. In Vietnam, a cornerstone of this etiquette is ‘lễ phép’. Taught from a young age, ‘lễ phép’ is more than just politeness; it embodies a complex set of behaviors demonstrating profound respect towards elders, parents, teachers, and those in authority. It’s an unspoken yet powerful language of reverence that shapes daily interactions, maintaining societal harmony.

Practically, ‘lễ phép’ manifests in various ways. This includes using specific respectful vocabulary and address terms, bowing slightly when greeting an elder, listening attentively, or offering help. For a 14-15-year-old in Vietnam, these expectations are a daily reality, evident in how they speak to grandparents, interact with teachers, or address older relatives. This ingrained respect reinforces familial bonds and community cohesion, reflecting a cultural value that prioritizes collective harmony and deference to wisdom. [I]

However, with globalization and digital connectivity, communication styles are rapidly transforming. [II] Modern interactions, especially among younger generations, often lean towards informality, influenced by global media and online platforms. Casual language, direct expressions, and peer-to-peer communication often contrast sharply with ‘lễ phép’. [III]

[IV] Despite the allure of modern informality, the core principles underlying ‘lễ phép’ remain profoundly important. At its heart, ‘lễ phép’ isn't merely about rigid rules; it’s about expressing genuine respect, gratitude, and acknowledging another person’s experience. These values—respect, humility, and appreciation—are timeless and universal. They foster stronger intergenerational relationships, promote understanding, and create a more harmonious social environment. Showing ‘lễ phép’ can bridge generational gaps and demonstrate that while communication styles may change, fundamental human decency endures.

Ultimately, the challenge for young people today is not to discard ‘lễ phép’ entirely, but to adapt it thoughtfully. Finding a balance where modern communication coexists with traditional values is key. This might mean maintaining respectful tones and polite language while also embracing more direct conversations when appropriate. True respect isn't about rote performance; it's about genuine intention. Navigating these nuanced expectations allows teenagers to honor their heritage while effectively engaging with the contemporary world, ensuring ‘lễ phép’ contributes to a respectful and connected society.
