In a world where academic success is often the main focus for teenagers, especially in Vietnam, it’s easy to think of hobbies as just a fun distraction. Many students believe they don't have time for anything other than homework and extra classes. However, this view is changing. A growing body of research shows that making time for 'play' is not a waste of time; it's a critical part of a healthy, balanced life.

The mental health benefits of having a hobby are significant. When your mind is full of formulas and facts, a hobby offers a crucial escape, helping to lower stress levels and prevent the burnout that can come from too much studying. Engaging in an activity you love, just for fun, is essential for emotional well-being. It allows your brain to rest and recharge, which can paradoxically improve your focus when you return to your schoolwork.

Hobbies can also be categorized into different types that develop different skills. 'Creative & Artistic' hobbies, such as painting, playing the guitar, or writing stories, are excellent for boosting imagination and self-expression. On the other hand, 'Strategic & Logical' hobbies, like coding, playing chess, or solving complex board games, sharpen your problem-solving abilities and critical thinking. This escape from academic pressure provides more than just a temporary break; it builds valuable life skills.

This understanding is growing in Vietnam's big cities. The rise of board game cafes in Hanoi and pottery workshops in Ho Chi Minh City shows that more people are seeking balance. So, instead of seeing a hobby as something that takes time away from studying, view it as an investment in yourself. Finding an activity you are passionate about is one of the best ways to stay motivated, creative, and happy during your teenage years.

Fish that migrate upstream to spawn, such as salmon, can no longer complete their life cycle. (38) __________.

Furthermore, dams trap sediments that would naturally flow downstream. (39) __________. The altered water flow and temperature below the dam also create an unnatural environment. (40) __________.

A. Without this regular supply of nutrients, the fertile land in downstream deltas can erode and shrink

B. The dam itself becomes a physical barrier, which is a major problem for many aquatic species

C. As a result, many native plants and fish struggle to survive, changing the ecosystem forever

D. This disruption affects not only the fish populations but also other animals in the food web
