When people recall precisely where they were and what they were doing at the moment they learned of some momentous public event, the resulting memory often feels extraordinarily ①vivid, as though it had been etched into the mind with photographic precision; researchers have termed such recollections flashbulb memories. Proponents of this concept once argued that the emotional intensity and surprise accompanying such events trigger a distinct neural mechanism that preserves details with unusual ②fidelity, effectively exempting them from the ③gradual decay that afflicts ordinary memories. Subsequent longitudinal studies, however, have complicated this picture considerably: when researchers compared accounts gathered within days of an event to accounts gathered years later, they discovered that details had frequently been altered, omitted, or even fabricated, even though the individuals reporting them expressed ④unwavering confidence in their accuracy. This persistent mismatch between subjective certainty and objective consistency implies that flashbulb memories, far from being flawless recordings, are ⑤accurate narratives shaped by rehearsal, media exposure, and the passage of time.

Imagine a man locked inside a room who does not understand a single word of Chinese, yet who possesses a giant rulebook written entirely in English. Slips of paper covered with Chinese characters are passed in through a slot, and by following the rulebook's instructions step by step, he produces replies that appear ①fluent to anyone outside. From the perspective of a native speaker reading the responses, the room seems to understand Chinese ②perfectly. Yet the man inside understands nothing at all; he is merely manipulating shapes according to formal rules, without grasping their ③meaning. This scenario was designed to challenge the assumption that a computer running a sophisticated program truly ④fails to understand language simply because it produces convincing output. Passing every external test of intelligence, the argument suggests, is not the same as possessing genuine understanding, since syntax alone can never generate ⑤semantics.

Long before humans learned to drill for oil, microorganisms had already mastered the art of converting sunlight and carbon dioxide into stored chemical energy. Modern biofuel research borrows this ability, cultivating algae or engineered bacteria in large tanks where they can be coaxed into producing oils and sugars that can be refined into fuel usable in existing engines. _______________. Engineers have also learned to tinker with the metabolic pathways of these organisms, boosting oil yield far beyond what any wild strain would naturally produce on its own. Despite this progress, producing biofuel at a cost competitive with fossil fuel remains difficult, since harvesting and processing the organisms consumes a substantial share of the energy the fuel itself will eventually provide.

When people face a difficult decision, they often weigh how painful it would feel to discover later that a different choice had been better. This anticipation of future regret frequently becomes the dominant factor shaping the final decision. Researchers have found that people feel sharper regret over losses that resulted from taking action than over identical losses that resulted from doing nothing, _______________. Ironically, this strategy of avoiding regret can itself produce outcomes that are later regretted even more deeply than the ones it was originally designed to prevent.

Consider a student who genuinely intends to study for tomorrow's exam yet, when the evening actually arrives, chooses to watch another episode of a favorite show instead, promising herself she will surely study harder next week. (A) Behavioral economists note that this preference weakens considerably once both options are pushed into the future, which is why planning a diet starting next month feels effortless compared with skipping dessert tonight. Such inconsistency helps explain why gym memberships go unused and retirement accounts remain underfunded, despite people's stated intentions. Recognizing this pull toward the present, therefore, allows individuals and institutions to design commitments that quietly protect long-term goals from short-term temptation. (B) People do not necessarily fail to understand that the future reward matters more; rather, whatever happens right now simply feels disproportionately more urgent and vivid than anything scheduled for later. (C) This pattern, in which the pull of an immediate pleasure overwhelms the value of a distant benefit, appears again and again across ordinary life, from postponed exercise to delayed savings.

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. (A) 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. (B) 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. 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. (C) Grid operators must therefore invest in infrastructure capable of accommodating this variability, rather than assuming renewable sources can simply replace fossil fuels without adjustment. Without such investment, integrating renewable energy could paradoxically undermine the very reliability that modern electricity grids are expected to provide.

As buildings account for a substantial share of global energy consumption, architects have increasingly turned to a design philosophy known as the passive house standard, which minimizes energy demand through the building's own structure rather than through mechanical systems. (A) Consequently, many architects regard passive house design not as a luxury for wealthy homeowners but as a practical model capable of reshaping mainstream construction. (B) Central to this approach is airtight construction, in which continuous insulation and sealed joints prevent conditioned air from leaking outward, thereby reducing the heating and cooling loads conventional buildings require. Triple-glazed windows, oriented to capture sunlight in winter while shading interiors in summer, further stabilize indoor temperatures without relying heavily on furnaces or air conditioners. (C) Ventilation systems equipped with heat exchangers also recover warmth from outgoing air, transferring it to incoming air so that comfort is maintained without excessive energy use. For example, some passive houses built in cold climates have reduced heating costs by more than ninety percent.

주어진 문장: This selective compression of memory is not random, however; it follows a strikingly predictable psychological pattern. When people look back on a multi-day journey, they rarely recall every hour with equal clarity; instead, memory tends to compress the entire experience into just a few representative moments. ( ① ) Psychologists have found that two points carry disproportionate weight in this process: the single moment when emotion, whether joy or discomfort, reached its highest intensity, and whatever happened right before the experience concluded. ( ② ) Consider two hikers who complete an identical five-day trek. ( ③ ) The first finishes with a grueling, rain-soaked final climb, while the second enjoys a calm, scenic descent on the last afternoon despite having endured an equally difficult ascent earlier in the trip. ( ④ ) Even though both hikers faced comparable hardship overall, the second is far more likely to remember the journey fondly, simply because the trip ended pleasantly. ( ⑤ ) This pattern reveals that overall satisfaction is not calculated as an average of every experienced moment; rather, it is shaped disproportionately by whichever moments felt most intense and by however the experience happened to end.

The practical consequence of this precision has been a dramatic acceleration in the pace of genetic research itself. Bacteria have been cutting up invading viral DNA for billions of years, long before any scientist thought to borrow the trick for use in a laboratory. ( ① ) The CRISPR-Cas9 system, as it is now known, relies on a short guide RNA that matches a specific DNA sequence, leading a scissor-like enzyme called Cas9 directly to that exact location in the genome. ( ② ) Once Cas9 arrives at the target site, it slices both strands of the DNA helix, and the cell's own repair machinery rushes in to mend the cut, often introducing a small change in the process. ( ③ ) By supplying the cell with a template during this repair step, scientists can direct that machinery to insert a specific new sequence. ( ④ ) This goes well beyond merely disabling the original gene. ( ⑤ ) What once required years of painstaking work to alter a single gene can now, with a properly designed guide RNA, be accomplished within days.

Political scientist Ted Gurr illustrated the pattern with what is often called the J-curve: revolutions tend to follow a period of sustained improvement that is then followed by a sudden reversal. Social unrest does not always emerge from the poorest conditions; it frequently erupts when circumstances are improving but not quickly enough to satisfy rising expectations. ( ① ) This paradox lies at the heart of relative deprivation theory, which holds that discontent arises less from objective hardship than from a perceived gap between what people expect and what they actually receive. ( ② ) Citizens who had grown accustomed to progress often feel suddenly cheated of gains they had come to regard as their due. ( ③ ) Because the theory centers on perception rather than raw statistics, it helps explain why relatively prosperous societies can experience intense protest. ( ④ ) Societies mired in long-standing poverty, meanwhile, sometimes remain comparatively quiet, having adjusted their expectations to match a bleak and unchanging reality. ( ⑤ )
