Air conditioners make summer days more comfortable, but using them ①incorrectly can harm your health. Doctors recommend keeping the difference between indoor and outdoor temperatures ②small, within about five or six degrees. A larger gap forces your body to adjust constantly, which can ③weaken your immune system. This sudden change often leads to headaches and fatigue. To avoid these problems, set your air conditioner to the ④lowest temperature possible, and open a window ⑤regularly to let fresh air in.

The Greenfield Public Library will offer a variety of special programs for students during summer vacation. The reading club encourages children to read at least one book per week and ①hide their thoughts from others. The writing workshop helps older students ②improve their essay skills. All programs are free, but registration is required in advance because space is ③limited. Interested students should sign up at the front desk or through the library's website. Materials such as notebooks and pencils will be provided for ④every session, so students can make the most of their ⑤vacation.

Many teachers and parents worry that today's teenagers are ①gaining the ability to read long, complex texts. National test scores show a slow ②decline in reading comprehension over the past ten years, and some experts blame smartphones and short videos for shortening students' attention spans. Other researchers disagree with this simple explanation. They point out that teenagers today read constantly, just in different forms, such as text messages, captions, and online articles. According to this view, the real problem is not that students read less overall, but that they rarely practice reading long passages without any ③interruption. A team of researchers recently found that students who read at least one full book every month scored ④noticeably higher on comprehension tests than students who mainly read short online posts. This result suggests that the format of reading, rather than simple screen time, may be the more important factor behind the ⑤changing scores.

Riding a bicycle is a great way to stay active during summer vacation, but safety should always come ①first. Wearing a helmet is essential, since it can ②prevent serious head injuries in an accident. It is also important to wear bright or reflective clothing so that drivers can see you ③clearly. Riders should always follow traffic signals and ride in the same direction as traffic, never against it, since going against traffic makes accidents much ④less likely. Carrying a water bottle is wise, since dehydration can cause dizziness and affect your ⑤balance.

Last week, I started feeling tired and had a mild headache every afternoon at school. At first, I thought I was just stressed about exams, but my mother told me it might be air-conditioning sickness, which happens when ___________. After doing some research, I learned a few simple ways to prevent it, such as wearing a light jacket indoors, drinking warm water, and stretching every hour.

Summer brings a wide variety of delicious fruits, but many of them spoil quickly in the heat. Knowing how to store fruit properly can help you avoid waste and enjoy fresher flavors. For example, ___________, while whole, uncut melons can be stored at room temperature until you are ready to eat them.

Many people throw away items that they no longer need. However, some students have started to buy and sell used goods instead of throwing them away. This practice, often called secondhand trading, takes place at flea markets or through simple online apps. When you buy a secondhand book or a used bicycle, you save money and reduce waste at the same time. For example, a jacket that no longer fits your older sibling can become a treasure for someone else. Giving an old item to a new owner is like giving a toy a second life. In contrast, throwing away useful items increases the amount of trash that ends up in landfills. Therefore, secondhand trading, which requires little effort, _______________. Small choices like this can make a big difference for our planet.

Every Wednesday evening, a small group meets in the corner of a quiet cafe, coffee cups in hand, ready to talk about a book they have all just finished. (A) Perhaps the greatest benefit is social rather than literary: strangers from very different backgrounds discover that they share the same doubts, laughter, and surprises over the very same pages. (B) Members also say that having a discussion planned in advance pushes them to finish books they might otherwise put down halfway through. (C) This is a book club, and its members insist that reading the same novel together changes the experience completely, because one person's small comment can reshape how everyone else understood the story.

When someone's heart suddenly stops beating, the brain begins to suffer damage within minutes unless blood keeps circulating, which is why the actions taken by an ordinary bystander before paramedics arrive can matter as much as the treatment given at the hospital. (A) Studies show that a person who receives CPR immediately from someone nearby is far more likely to survive than one who waits for professional help to arrive. (B) Despite this, many people hesitate to start chest compressions, worried that they might break a rib or make the situation worse. (C) Medical instructors respond to this fear: a cracked rib heals, but a brain deprived of oxygen for too long does not.

This eagerness to get moving is understandable, but it can come at a real physical cost. Physical education class often feels like the one period of the day when students can finally move freely, which sometimes leads them to skip the warm-up routine that teachers insist on before any real activity begins. ( ① ) Cold muscles, however, are noticeably less flexible than warmed ones, and stretching a stiff hamstring or ankle too quickly can cause a strain that keeps a student off the field for weeks rather than minutes. ( ② ) Coaches often compare an unwarmed muscle to a cold rubber band that snaps rather than stretches under sudden pressure. ( ③ ) Beyond warming up, wearing proper footwear matters more than most students realize; running in worn-out sneakers with little grip left on the sole significantly raises the chance of a twisted ankle on a gym floor or an outdoor field. ( ④ ) Reporting a minor pain immediately, rather than pushing through it to finish a game, also prevents a small issue from becoming a repeated injury that lingers for an entire season. ( ⑤ )
