Every day, cities around the world produce enormous amounts of trash. Traditionally, this material is buried in large holes in the ground called landfills. However, landfills take up a lot of space and can pollute the environment. To solve this problem, some cities are using an innovative technology called Waste-to-Energy (WtE), which turns everyday garbage into a useful resource: electricity.

The process begins when garbage trucks arrive at a WtE plant. First, the trash (21) __________ to a large pit. From there, it is moved into a special, high-temperature furnace called an incinerator. Inside the incinerator, the trash is burned at extremely high temperatures, which greatly reduces its volume. The main effect of this controlled burning is the production of a massive amount of heat.

Next, the heat generated from burning the waste is not wasted. It is used to heat water in a large tank called a boiler. The intense heat causes the water to boil and transform into high-pressure steam. This step is similar to how a traditional power plant works, but instead of using coal or gas as fuel, it uses the energy stored in our garbage.

This high-pressure steam is then directed through pipes to a machine called a turbine, which has many blades. The force of the steam causes the turbine to spin at a very high speed. The spinning turbine is connected to a generator, and its movement is used to generate electricity. (22) __________, filters are used to clean the gases produced during burning before they are released into the atmosphere, which helps to minimize air pollution. The final electricity is sent out through the power grid to homes and businesses (23) __________ need it.

In conclusion, the WtE process is a clever way to manage waste and create energy simultaneously. It transforms something we want to get rid of into a (24) __________ resource. Although it's not a perfect solution for all waste problems, many modern cities now consider it an important part of their environmental strategy, helping them to reduce landfills and provide power to their citizens.

From ancient heroes to modern innovators, humans have always looked for figures to admire and emulate. These individuals, often called role models, serve as powerful sources of inspiration, guidance, and a blueprint for success. They might be historical figures, celebrities, or even family members embodying values we aspire to. Their presence can significantly influence our aspirations, showing us what's possible and how to begin navigating our own paths. [I]

In Vietnam, this phenomenon is clearly visible among young people. Public figures like singer Sơn Tùng M-TP are prime examples, captivating many with their unique style and ambitious creative drive. He embodies a success that resonates beyond traditional academic fields, showcasing how passion and innovation can lead to widespread admiration. [II]

For teenagers, thinking about who you admire and why is more than just a casual thought; it's a profound exercise in self-discovery. [III] Whether your idol is a K-pop star, a scientist, or an older sibling handling challenges with grace, understanding their appeal clarifies your own values. What qualities do you find admirable – their discipline, curiosity, or resilience? Recognizing these traits in others helps identify what truly matters, serving as a vital step in setting meaningful goals for your own life.

This leads to an important question: do you need a role model? [IV] While many find immense benefit, it's not always about having one single, perfect individual to follow. Sometimes, inspiration comes from a mosaic of people, each contributing a different strength or lesson. You might learn work ethic from one, empathy from another, or creativity from a third. The key is to actively seek out positive influences, be they historical figures or everyday heroes in your community. Your "role model" might even evolve as you grow and your aspirations shift.

Ultimately, the power of a role model lies in their ability to illuminate possibilities and guide us. They offer tangible examples of dedication, innovation, and courage, providing a framework against which we measure our efforts and dreams. Whether you choose to follow a famous personality or draw quiet strength from someone closer to home, identifying and appreciating admirable qualities in others is a powerful tool. It helps us not only understand the world better, but also clarify our place within it, setting us on a path of continuous personal growth.
