If you have ever spent a day at the beach, you have likely noticed the ocean's water level rising and falling. This regular movement is known as the tide. This amazing natural (35) __________ happens twice a day in most coastal areas, shaping the landscape and affecting marine life. But what exactly causes this predictable cycle of high and low tides?

The primary reason for ocean tides is the gravitational pull of the Moon. (36) __________ its relative closeness to our planet, the Moon's gravity exerts a strong force on Earth. This force is powerful enough to affect the entire planet, but its effect on the oceans is most noticeable. The water on the side of Earth facing the Moon is (37) __________ towards it, creating a bulge.

Interestingly, a similar bulge is also created on the opposite side of Earth. This second bulge is caused by the planet being pulled toward the Moon, leaving the water on the far side behind. This process (38) __________ two high tides at the same time on opposite sides of the planet. The areas between these bulges experience low tides. This entire system, combined with (39) __________ Earth's rotation, results in the regular tidal cycle we observe.

While the Moon is the main driver, the Sun also influences the tides. Its gravitational pull is much stronger than the Moon's overall, but because it is so much farther away, its tidal effect is weaker. The Moon does (40) __________ of the work in creating tides. If the Sun were the only celestial body affecting our oceans, tides (41) __________ significantly smaller and less complex.

In summary, ocean tides are a complex interplay of gravitational forces, mainly from the Moon but also from the Sun. An old mariner once remarked that he (42) __________ how the sea seemed to breathe in and out each day. This poetic description captures the essence of this constant, powerful hydrological force that has fascinated humanity for centuries.

From our parents and older siblings to historical figures and modern-day celebrities, role models are all around us. They are individuals we look up to and wish to emulate. But in an age of constant information and endless choices, a key question arises for many teenagers: is having a specific role model truly necessary for personal growth and success? Or is it an outdated concept in our complex world?

The argument for having role models is strong. They can act as a guiding light, providing a clear blueprint for what is possible to achieve. When we see someone who has successfully navigated a path we are interested in, it gives us the motivation to pursue our own goals. A role model can make an ambitious dream feel more attainable, transforming a vague wish into a concrete plan. They show us the required discipline, resilience, and hard work, which can inspire us to push through our own difficulties and stay focused.

However, the idea of a single, perfect role model has its drawbacks. Placing someone on a pedestal can create unrealistic expectations and immense pressure to live up to an idealized image. We may feel disappointed when we discover our heroes are human and have flaws. Furthermore, inspiration is not limited to traditional fields like science or politics. In Vietnam, for instance, a creative figure like the singer Sơn Tùng M-TP has become a role model for many young people, not for academic achievements, but for his unique style and artistic ambition. This shows that valuable lessons can come from many different sources.

Perhaps a more modern and healthier approach is to not search for one perfect person to copy, but to build a personal 'board of advisors' in our minds. This means identifying specific, admirable qualities in a variety of people. You might admire a scientist's analytical mind, a K-pop star's dedication, and a family member's kindness. By drawing inspiration from these different sources, we can learn from them all without the pressure of trying to be a perfect copy of any single individual. This method allows for a more flexible and personalized path to self-development.

Ultimately, the goal is not to become a clone of someone else but to use the inspiration they provide to construct our own unique identity. Role models, whether one or many, are most useful when they serve as a starting point for our own journey of self-discovery. The true value lies not in imitation, but in the reflection and goal-setting that our admiration for others inspires within us.
