Passage 1 — Sleep and Learning
Teenagers often have busy schedules that include school, homework, extracurricular activities, and time with friends. As a result, many students do not get enough sleep. Researchers have found that sleep plays an important role in attention, memory, and emotional regulation. When students sleep too little, they may find it harder to concentrate in class or remember information they studied the night before.
Technology can also affect sleep habits. Using phones or laptops late at night may delay the time students fall asleep, especially when they continue checking messages or watching videos. Experts therefore recommend developing a consistent bedtime routine and reducing stimulating activities shortly before sleep.
Getting enough sleep does not guarantee high grades, but healthy sleep habits can support the mental processes students need for effective learning.
Passage 2 — Green Spaces in Modern Cities
As cities grow, planners face pressure to provide housing, transportation, public services, and places for recreation. Urban green spaces—including parks, community gardens, and tree-lined streets—can contribute to several of these goals. Trees provide shade, vegetation can absorb some rainwater, and parks can offer residents places to exercise and socialize.
However, simply creating a park does not guarantee that every resident will benefit equally. Some neighborhoods have easy access to safe, well-maintained green spaces, while others may have very few. In addition, green spaces require long-term maintenance. Without proper care, facilities may become unsafe or vegetation may decline.
For these reasons, many urban planners argue that cities should consider not only the total amount of green space but also its location, accessibility, and maintenance. A well-designed network of green spaces can improve urban life, but effective planning determines how widely those benefits are shared.
