Safety signs surround us so constantly, from a yellow diamond ①warns of a curve ahead to a red octagon commanding a full stop, that most people stop consciously reading them soon after learning to drive. This is precisely the outcome that sign designers hope ②to avoid, since a sign that requires careful thought to interpret in an emergency has already failed at its purpose. Colors and shapes are chosen deliberately rather than randomly: red almost universally ③signals danger or prohibition, yellow signals caution, and green marks safety. Symbols replace text wherever possible for the same reason, ④allowing a running figure or a flame icon to communicate instantly to someone who may not speak the local language. Ignoring a familiar sign because it has become part of the background remains one of the most common and ⑤preventable causes of accidents in public spaces.

Riding a bicycle is a great way ①to stay active during summer vacation, but safety should always come first. Wearing a helmet is essential, since it ②can prevent serious head injuries in an accident. Riders should always ③follow traffic signals and ride in the same direction as traffic, never against it. Carrying a water bottle is wise, since dehydration ④can cause dizziness and affect your balance. Choose bike paths or quiet streets ⑤whenever possibly, rather than busy roads with heavy traffic.

Electric scooters have become a common sight on city sidewalks, ①offering a quick way to cover short distances, yet most riders climb on without ever putting on a helmet. Part of the problem is that renting a scooter takes only a few taps on a phone screen, while finding and carrying a helmet ②requires planning that many riders simply skip. Emergency room doctors note that scooter-related head injuries have risen sharply in recent years, ③closely tracking the rise in scooter popularity itself. Unlike a bicycle, which typically requires balance skills built up over years of practice, an electric scooter can reach a surprising speed within seconds, often faster than new riders ④expecting from something that looks simple to operate. Cities that have begun requiring helmets for scooter rentals ⑤report a measurable drop in serious injuries.

Summer is the best time to enjoy swimming pools, rivers, and beaches with family and friends. However, water activities can be completely ①safe without proper preparation. First, always swim in areas that are ②supervised by a lifeguard, and never swim alone even if you are a strong swimmer. Second, check the weather and water conditions before entering the water, since strong currents can make swimming extremely ③dangerous. Third, wear a life jacket in open water, especially if you are a beginner. Taking a break every hour will help you stay ④energetic, and learning basic rescue skills will make you more ⑤prepared for emergencies.

One of the most overlooked risks is setting up a tent too close to a campfire, since a sudden gust of wind can carry a spark onto dry fabric faster than anyone expects. Food storage is another area where casual habits create danger: leaving snacks inside a tent can attract wildlife looking for food. Experienced campers also stress the importance of checking a weather forecast before leaving, since _______________. None of these precautions demand special equipment or skill; they simply require campers to treat the outdoors with the same caution they would show in any unfamiliar environment.

Every summer, doctors warn about the danger of heatstroke, a serious condition in which ___________. This condition can be life-threatening if it is not treated quickly. To prevent heatstroke, drink plenty of water throughout the day, avoid outdoor activities during the hottest hours, and wear light, loose clothing.

Drinking enough water is especially important during the hot summer months. When you sweat a lot, your body loses not only water but also important minerals called electrolytes. If you do not replace these losses, ___________. Experts recommend drinking water regularly throughout the day, rather than waiting until you feel thirsty.

Last year our art club received a set of digital drawing tablets, and I assumed switching from paper would feel like cheating, since a screen seemed to remove the physical struggle of real drawing. (A) What the tablet does offer is the freedom to undo a mistake instantly and experiment with colors without wasting paper, which encourages artists to take risks. Several members who once avoided painting now try bold new styles daily. (B) After a few weeks of practice, though, I noticed the tablet demanded a different kind of skill rather than an easier one. (C) Because there is no paper texture to guide the pen, beginners often press too hard or draw shaky lines until their hand adjusts to the smooth glass surface.

This sudden and violent stop is precisely what causes so many of the most severe injuries in a crash. Seatbelts are so woven into the experience of riding in a car that many passengers buckle them without thinking, yet a surprising number of teenagers still skip them for short trips, assuming that a five-minute drive to a friend's house does not carry much risk. ( ① ) Traffic safety data tell a different story: most fatal crashes occur within a few kilometers of home, on roads drivers know so well that they let their guard down. ( ② ) In a collision, a body traveling at a moderate speed continues moving forward at that same speed until something stops it, and without a seatbelt, that something is often the windshield or the dashboard rather than a slower deceleration. ( ③ ) A seatbelt spreads the force of a sudden stop across the stronger parts of the body, such as the hips and chest, instead of concentrating it on the head and neck. ( ④ ) Despite decades of public awareness campaigns, seatbelt use for backseat passengers remains lower than for those sitting in the front. ( ⑤ )

She explained that sitting in a cold, air-conditioned room for too long can make people feel weak and achy. Last week, I started feeling tired and had a mild headache every afternoon at school. ( ① ) At first, I thought I was just stressed about exams, but my mother told me it might be air-conditioning sickness. ( ② ) After doing some research, I learned a few simple ways to prevent it. ( ③ ) First, I began carrying a light jacket to wear indoors, and I made sure to drink warm water instead of only cold drinks. ( ④ ) I also started stretching and walking around every hour instead of sitting still all day. ( ⑤ ) Within a few days, my headaches disappeared, and I felt much more energetic.
