Suspension bridges are masterpieces of engineering, famous for their elegant design and ability to span vast distances like wide rivers or bays. But how do these massive structures stay up? The secret lies in a clever distribution of forces. At its most basic, (35) __________ suspension bridge works by hanging the road from cables, which then transfer the weight to towers and finally to the ground.

The process begins with the road itself, which is called the (36) __________. This deck is where cars and people travel. The weight of the deck, and everything on it, is supported by hundreds of vertical steel cables called suspenders. These suspenders are connected directly to the deck, and they hang down from the main, much larger cables above.

The main cables are the most critical components. They stretch from one end of the bridge to the other, passing over the tops of two tall towers. All the weight from the suspender cables is transferred to these main cables, pulling on them and creating an immense force called tension. (37) __________, these cables are made from thousands of individual steel wires bundled together for maximum strength. (38) __________ the weight from the deck upwards into the main cables is the first major step in distributing the load safely.

Next, the main cables are draped over the towers. The towers' job is to (39) __________ the cables and transfer the load down to the earth. While the cables are under tension (a pulling force), the towers are under compression (a squeezing force). They must be strong enough to support the weight from the cables and push it directly into their foundations in the ground. If the main cables (40) __________, the entire structure would immediately collapse, showing how vital their connection is.

Finally, at each end of the bridge, the main cables are secured into massive concrete blocks called anchorages, which are buried deep in the ground. These anchorages are (41) __________ of the entire system, resisting the pull of the cables and keeping everything stable. An engineer once explained that the delicate balance between tension and compression (42) __________ the secret to a suspension bridge's long-lasting success.

Across the globe, elite athletes are celebrated for their incredible achievements, but behind every medal lies a story of immense dedication and personal sacrifice. They push their bodies and minds to the absolute limit for a chance at glory and to bring pride to their nation. In Vietnam, few athletes embody this spirit more than swimmer Nguyễn Thị Ánh Viên. Nicknamed the 'Little Mermaid,' she became a national hero whose journey from a small village in Cần Thơ to the top of the podium has inspired millions.

Ánh Viên’s path to greatness was built on an almost superhuman training schedule. While other teenagers might spend their afternoons with friends, Ánh Viên spent up to ten hours a day in the swimming pool, covering distances of nearly 50 kilometers. Her life was a cycle of swimming, eating, and sleeping. This rigorous routine was complemented by a strict, scientifically planned diet to maintain peak physical condition. Furthermore, this commitment required her to spend long periods far from home, training in specialized facilities abroad and missing out on the simple joys of family life.

The fruits of this labor were spectacular. Ánh Viên dominated the Southeast Asian (SEA) Games, accumulating an incredible 25 gold medals over her career, a feat that cemented her legendary status in Vietnamese sports. Each victory was not just a personal triumph but a moment of collective national pride. She was more than a swimmer; she was a symbol of what could be achieved through relentless hard work. Behind the scenes, her coaches and family provided a crucial support system. They constantly encouraged her and managed the intense pressures of her career, allowing her to focus solely on her performance.

However, physical strength alone does not create a champion. Ánh Viên's success was also fueled by her extraordinary mental fortitude. Competing at such a high level brings immense psychological pressure, from both public expectations and personal ambition. Developing the focus to block out distractions, the resilience to bounce back from a disappointing race, and the mental toughness to endure grueling training day after day were just as important as her powerful swimming strokes. This mental conditioning is often the unseen factor that separates good athletes from truly great ones.

For teenagers facing their own challenges, like preparing for important exams, Ánh Viên's story offers a powerful lesson. It's a reminder that success is rarely a matter of just talent or luck. It is the result of discipline, perseverance, and the courage to make sacrifices for a long-term goal. Her legacy is not just in the medals she won, but in the powerful message that with unwavering dedication, any ambitious dream is within reach.
