Among strategies for improving concentration, the Pomodoro Technique remains one of the most widely ①recommended methods for students and workers. This technique involves working with full attention for twenty-five minutes, then ②taking a short five-minute break before starting the next session. After completing four of these cycles, a longer break of fifteen to thirty minutes ③is usually taken to allow mental recovery. The method assumes that sustained focus becomes harder to maintain as time passes, so frequent short breaks prevent mental fatigue from ④build up. Students preparing for exams report finishing reading assignments faster when they follow this structured rhythm instead of studying without interruption. Office workers find that dividing large projects into short, timed intervals makes overwhelming tasks feel more manageable. Because each interval has a clear start and end, procrastination becomes less tempting, since beginning a single twenty-five-minute session requires less commitment ⑤than beginning an entire project.

The city government has launched a summer energy-saving campaign ①to reduce electricity use during the hottest months. As air conditioners run constantly, power demand ②rises sharply and can strain the electricity grid. Residents are asked ③setting air conditioners no lower than twenty-six degrees Celsius. Turning off lights and unplugging unused electronics can also make a noticeable ④difference. Families ⑤who reduce their electricity use by more than ten percent will receive a discount.

Summer heat can be just as dangerous for pets ①as it is for people. Dogs and cats cannot cool their bodies as easily as humans, so owners must ②take extra care during hot days. Avoid walking your dog during the hottest hours, since hot pavement ③can burn sensitive paws. Never leave a pet alone in a parked car, even for a few minutes, because the temperature inside ④rising dangerously fast. If your pet seems unusually tired or ⑤refuses to move, contact a veterinarian right away.

Hospitals are increasingly adopting artificial intelligence tools that can scan medical images and flag potential tumors faster and, in some trials, more accurately than experienced radiologists. Patients understandably welcome any technology that catches disease earlier, yet the growing reliance on these tools raises an uncomfortable legal question that hospitals ① have only begun to address. When an AI system misses a diagnosis that a human doctor would likely ② have caught, responsibility becomes difficult to assign. The doctor may argue that they simply trusted a tool the hospital ③ required them to use, the hospital may argue that the software company guaranteed its accuracy, and the software company may argue that no algorithm can ④ expect to be perfect. Until legal systems clarify this chain of responsibility, patients harmed by an algorithmic error may find themselves with no clear party ⑤ to hold accountable.

Central High School will host its annual career fair next Thursday. More than thirty companies will set up booths to introduce ①similar careers. Students can talk directly with workers from fields such as medicine, engineering, design, and media. Each booth will offer a short activity so visitors can ②experience a small part of the job. Teachers strongly ③encourage all students to attend. Meeting professionals in person often opens doors to careers students never ④considered before. The fair will end at 3 p.m., and light refreshments will be ⑤provided for all visitors.

The discovery of CRISPR gene-editing technology gave scientists a tool ① precise enough to correct a single mistaken letter in the human genome, raising hope for curing inherited diseases that have resisted treatment for generations. Yet the same precision that makes CRISPR so promising also makes it ② dangerous in the wrong hands. Editing a gene in a sperm, egg, or early embryo does not simply change one patient; it alters the genetic code passed down to every future generation, a decision no single person should be allowed to make ③ alone. Scientific organizations around the world have therefore drawn a careful line, permitting gene editing to treat disease in existing patients while ④ permitting any edit that would be inherited by their descendants. Critics worry, however, that as the technology becomes cheaper and more widely available, this line will become harder to enforce than it is to draw ⑤.

On the first day of the club fair, the gym was filled with noise and color. Every table had a banner, and members called out to new first-graders like me. My friend Somin dragged me toward the robotics club, insisting it would suit me. However, the long list of coding projects looked too ① complicated for a beginner. Just then, I noticed a ② quiet table where students were sketching posters together. A calm senior named Jian explained that the art club ③ rejected complete beginners. She showed me a sketchbook filled with simple drawings by first-year members. Her gentle voice made me feel ④ relaxed for the first time that day. Without much thought, I wrote my name on the sign-up sheet before leaving. Walking out of the gym, I finally felt that I ⑤ belonged in this new school.

As more businesses move their operations online, cyberattacks have become one of the most serious threats facing modern companies. In response, demand for cybersecurity professionals has surged across nearly every industry. Despite this expansion, experts estimate that ___________, largely because the number of qualified applicants has not kept pace with rapidly increasing demand. This shortage suggests that cybersecurity will remain a promising career path for years to come.

Consider a large heap containing ten thousand grains of sand. (A) Something has clearly gone wrong along the way, since no reasonable person would call one grain of sand a heap, but pinpointing exactly which single removal transformed a heap into a non-heap seems impossible. (B) Nearly everyone agrees that removing a single grain from such a heap leaves another heap behind, since surely one grain could never make the difference between a heap and a non-heap. (C) Yet if this principle is applied repeatedly, grain by grain, the heap eventually shrinks to a single lonely grain, or even to no grains at all, and logic alone seems to force us to accept that this final result still counts as a heap.

This is because the sun's rays are strongest during these hours, even on cloudy days. Strong summer sunlight can seriously damage your skin if you are not careful. ( ① ) Ultraviolet rays can cause sunburn, wrinkles, and even skin cancer over time. ( ② ) To protect your skin, apply sunscreen with a high SPF before going outside, and reapply it every two hours. ( ③ ) Wearing a hat and sunglasses also helps shield your face and eyes from direct sunlight. ( ④ ) In addition, try to stay in the shade between eleven in the morning and three in the afternoon. ( ⑤ ) After spending time outdoors, cool your skin with a damp towel and apply a moisturizer.
