Heatstroke happens when the body's temperature ①rises too high and cannot cool itself down. To prevent heatstroke, you should drink plenty of water throughout the day, ②even if you do not feel thirsty. If you notice symptoms such as dizziness or a very high body temperature, ③move to a shaded place immediately. Children, ④who sweat less than adults, are especially at risk of heatstroke. It is also wise ⑤avoiding outdoor activities between noon and five o'clock, when the sun is strongest.

Blue, for instance, is frequently used by financial and technology companies because it tends to evoke feelings of ①trust and stability. Green typically signals ②freshness or environmental responsibility, making it a popular choice for organic food brands. Despite these general patterns, cultural context matters significantly, since a color that suggests luck in one country might suggest ③mourning in another. Marketers who ④ignore these cultural differences risk sending ⑤intended messages to international audiences. For this reason, companies expanding into new markets often conduct extensive research before finalizing a logo's color scheme.

Standard economic theory assumes that money is fungible, meaning that a dollar earned as salary is functionally ①identical to a dollar received as a tax refund or won in a lottery. In practice, however, people routinely sort their finances into separate mental accounts, treating money differently depending on its source or intended purpose. A household that would never dip into its retirement savings to pay for a vacation might nonetheless spend an unexpected bonus on that very trip without ②hesitation, even though both sums are, in strictly financial terms, equally available for either purpose. This ③compartmentalization can produce decisions that appear ④consistent when viewed through a purely rational lens: the same individual who diligently saves a portion of every paycheck may simultaneously carry high-interest credit card debt, effectively paying more to borrow than they earn on their savings. Mental accounting is not always harmful, however; by assigning specific categories to specific funds, individuals can also impose useful ⑤discipline on their spending, preventing money earmarked for essential needs from being diverted toward impulsive purchases.

Classical economic models typically assume that people discount future rewards at a constant rate, valuing a reward received later somewhat less than an identical reward received now, but doing so ①consistently across all time horizons. Empirical observation, however, reveals a different pattern: people apply a much ②steeper discount to the immediate future than to the distant future. When the reward or cost in question lies safely in the future, its emotional weight remains ③vivid, allowing rational long-term goals to dominate one's stated intentions. Once that same reward or cost draws near, however, its immediacy triggers a disproportionately strong emotional pull, frequently ④overriding the very plans made earlier with such apparent confidence. This dynamic helps explain chronic procrastination, since tasks that carry long-term benefits are perpetually ⑤deferred in favor of activities offering more immediate satisfaction.

Last spring, Mina joined the school environmental club because she wanted to make a difference. At first, she felt nervous about speaking in front of the other members. However, the club leader, who had been recycling for years, welcomed her warmly. Every Friday, the members walked around the school picking up trash near the playground. Mina soon realized that this weekly habit was like watering a small plant every day. For example, a single plastic bottle left outside could take hundreds of years to disappear. Therefore, the club decided to place clear recycling bins in every classroom. In contrast to her early doubts, Mina _______________. Her classmates started separating cans and paper without being reminded by teachers. By the end of the semester, Mina had become an active member.

A biosensor works by pairing a biological component, such as an enzyme or antibody, with an electronic device that converts a biological reaction into a signal a computer can read. When the target molecule binds to the biological component, it triggers a small measurable change that the device translates into a readable number. This design has already transformed diabetes management, letting patients monitor blood sugar continuously through a small sensor worn under the skin rather than pricking a finger several times a day. Engineers are now racing to extend the same principle to detect subtler targets, from cancer cells circulating in the bloodstream to trace contaminants in drinking water. _______________.

Not all relationships that people form are equally close or meaningful. (A) Robin Dunbar, an anthropologist, argued that the human brain can only support about one hundred fifty stable relationships at once. (B) Consequently, most of the hundreds of online followers a person accumulates never become genuinely close acquaintances. (C) This cognitive limit applies regardless of how many friends or followers a person collects on social media.

Storing a damp umbrella in a closed bag can cause mold and a bad smell. During the rainy season, umbrellas and raincoats become essential items for daily life. ( ① ) After using a wet umbrella, open it fully and let it dry in a well-ventilated place before folding it again. ( ② ) Raincoats should also be hung up to dry completely before being put away. ( ③ ) It is helpful to wipe off dirt and mud with a soft cloth, since dirt left on the fabric can damage the waterproof coating. ( ④ ) In addition, check the umbrella's frame regularly for rust or broken parts. ( ⑤ ) Taking care of these simple items will help you stay dry all season long.

This is because thirst is often a sign that your body is already dehydrated. Drinking enough water is especially important during the hot summer months, and experts recommend drinking regularly rather than waiting until you feel thirsty. ( ① ) When you sweat a lot, your body loses not only water but also important minerals called electrolytes. ( ② ) If you do not replace these losses, you may feel tired, dizzy, or even suffer from muscle cramps. ( ③ ) It is best to avoid sugary drinks and too much caffeine, since they can make dehydration worse. ( ④ ) Instead, choose plain water or drinks that contain electrolytes, especially after exercise. ( ⑤ ) Eating water-rich fruits and vegetables can also help you stay hydrated.

That two- or three-hour gap may look modest on paper, but its effects accumulate quickly, touching everything from mood to memory. Across the world, teenagers are chronically short on sleep, often getting two or three hours less than the eight to ten hours experts recommend for their age. ( ① ) Part of the problem lies in biology: as puberty begins, the body's internal clock naturally shifts later, making it difficult for teenagers to fall asleep before eleven at night. ( ② ) Yet school start times rarely adjust to this shift, forcing students to wake before their bodies are ready. ( ③ ) The consequences extend well beyond simple tiredness. Chronic sleep loss during adolescence has been linked to impaired concentration, weakened memory, and a higher risk of anxiety and depression. ( ④ ) It can also disrupt the hormones that regulate appetite, contributing to unhealthy weight gain over time. Some school districts have experimented with delaying start times by even thirty minutes, and early results suggest that students who gain that extra rest show improved grades, better mood, and fewer tardy arrivals. ( ⑤ ) Despite this evidence, changing entrenched school schedules remains a slow and contentious process.
