The discovery of CRISPR gene-editing technology gave scientists a tool precise enough ①to 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 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 ②passed down to every future generation, a decision no single person should ③allow to make alone. Scientific organizations around the world have therefore drawn a careful line, ④permitting gene editing to treat disease in existing patients while banning any edit that would be inherited by their descendants. Critics worry, however, that this line will become harder to enforce than it ⑤is to draw.

Time blocking is a time-management technique in which a person divides the day into fixed blocks. Each block is then assigned to a single task. Instead of relying on a loose to-do list, the person decides exactly when each task will start and end. This approach ①lowers the mental effort of deciding what to do next, since the schedule already provides the answer. It also ②limits multitasking, because each block is reserved for only one activity at a time. For instance, a student may block ninety minutes for math practice, leaving no room for messages or web browsing. Because each block has a ③vague boundary, unfinished work is ④less likely to quietly spread into the next task. Many people who adopt time blocking feel ⑤more organized throughout the day.

Many people believe that building a new habit requires strong willpower or motivation. However, psychologist BJ Fogg argues that habits form more ①easily when a behavior itself becomes simple to perform. His theory, called the Fogg Behavior Model, states that a behavior happens only when motivation, ability, and a prompt occur together. When motivation is ②low, the model suggests, the task must be made extremely ③difficult, or it will not happen at all. For instance, a person who wants to exercise daily succeeds more often by committing to one push-up than to a long workout. Fogg calls this idea the law of ④least effort, since people naturally choose the option requiring the least energy. A student who wants to read more might leave a book open on the desk rather than setting a vague goal. By lowering the required effort, people reduce the ability barrier and make steady action far more ⑤achievable.

Attention all club leaders: applications for the club budget are now ①closed. If your club wants support for materials, events, or competitions, please follow the steps below. First, download the budget request form from the school website and fill in your club's name, purpose, and requested amount. Second, attach a short plan explaining how the money will be used, since forms without a clear plan will not be reviewed. Third, submit the ②completed form to the teacher in charge of student activities by August 14th. Applications received after the deadline will not be ③accepted. Once submitted, each request will be reviewed by the budget committee, which meets every Friday. ④Approved clubs will receive their funds within two weeks, and results will be posted on the club bulletin board. Please contact Mr. Han in the activities office if you have any ⑤questions.

Yesterday, I visited my school's career counselor because I felt confused about my future. She listened carefully and then asked me a simple question: what activities make me lose track of time? I answered that designing posters for school events always felt exciting. She smiled and said that this kind of clue often reveals ___________, more than any test score can. She suggested that I try combining my two interests by exploring careers such as scientific illustration or product design.

A planner is only useful if you actually use it well throughout the year, not just on January first. (A) For example, checking off completed tasks each morning helps you build momentum and stay motivated throughout the week. (B) Reviewing your notes every Sunday allows you to notice patterns and adjust your goals for the following week. (C) The most important step is to write one clear, specific goal at the top of each month.

주어진 문장: In practice, however, building such extensive networks demands years of planning and substantial financial resources. As solar and wind power expand rapidly across national grids, engineers face a challenge that receives far less public attention than the construction of the generating facilities themselves. ① Unlike conventional power plants, which can adjust their output to match demand at almost any moment, solar panels and wind turbines generate electricity only when sunlight or wind is available, producing supply that fluctuates constantly. ② This intermittency means that grid operators must balance supply and demand even when renewable output suddenly drops, such as when clouds cover a solar farm or wind speeds fall. ③ One proposed solution involves large-scale battery storage systems, which absorb surplus electricity generated during periods of high output and release it later when generation declines. Another approach relies on expanding transmission networks across wider regions, so that electricity generated in a sunny area can be redirected to places experiencing a shortfall. ④ Grid operators must therefore invest in infrastructure capable of accommodating this variability, rather than assuming renewable sources can simply replace fossil fuels without adjustment. ⑤ Without such investment, integrating renewable energy could paradoxically undermine the very reliability that modern electricity grids are expected to provide. ① ② ③ ④ ⑤

주어진 문장: This is precisely why scientists treat these thresholds with such urgency, rather than viewing them as distant, abstract possibilities. Climate scientists frequently warn about tipping points, thresholds beyond which a small additional change triggers a large, often irreversible shift in the climate system. ( ① ) Unlike gradual warming, which unfolds steadily over decades, crossing a tipping point can produce dramatic consequences within a short period. ( ② ) For instance, as Arctic ice melts, it exposes darker ocean water that absorbs more sunlight than reflective ice, accelerating further melting in a self-reinforcing cycle. ( ③ ) Similarly, scientists worry that a major ocean current, which currently redistributes heat across the planet, could slow dramatically if enough freshwater from melting glaciers dilutes the surrounding seawater. ( ④ ) Once such thresholds are crossed, restoring the original balance may become nearly impossible, even if emissions are later reduced. ( ⑤ ) Therefore, researchers argue that preventing these transitions matters more than merely slowing average temperature increases. Identifying how close each system stands to its threshold remains one of the most urgent challenges in climate research.

주어진 문장: Some researchers even suggest that painting rooftops white could further help reflect sunlight away from buildings. On a summer evening, downtown streets often feel noticeably hotter than nearby parks or suburban neighborhoods, even after the sun has set. ( ① ) This phenomenon, known as the urban heat island effect, occurs when cities retain more heat than surrounding rural areas because of their dense concentration of asphalt, concrete, and buildings. ( ② ) Unlike soil or vegetation, which absorb and release heat gradually, these man-made surfaces absorb sunlight during the day and slowly radiate it back at night, preventing temperatures from cooling. ( ③ ) Tall buildings packed closely together also block wind, trapping warm air within narrow streets. ( ④ ) In contrast, areas with abundant trees and open water naturally stay cooler, since plants release moisture that helps lower surrounding temperatures. To reduce this effect, many cities have begun installing rooftop gardens and expanding public parks, hoping that additional greenery will absorb less heat than pavement does. ( ⑤ )

There is also a quieter cultural cost that rarely appears in productivity reports. Sensors buried in the soil now report moisture levels in real time, drones survey entire fields for signs of disease within minutes, and automated systems adjust irrigation without a farmer ever walking the rows. ( ① ) For large operations with the capital to invest, these tools have measurably increased yields while reducing water waste. ( ② ) Smaller family farms, however, often cannot afford the upfront cost of this equipment. ( ③ ) Some worry that the gap between high-tech and traditional operations will only widen as the technology advances further. ( ④ ) Generations of farming knowledge, passed down through direct observation of soil, weather, and crops, risk being replaced by dashboards and automated alerts. ( ⑤ )
