A plastic bag that fully decomposes within months rather than lingering for centuries sounds almost too convenient to be real, yet certain bioplastics on the market ①do exactly that under the right conditions. Unlike conventional plastic, derived almost entirely from petroleum, many bioplastics are ②synthesized from renewable feedstocks such as corn starch or sugarcane, sometimes with the help of bacteria engineered to produce plastic-like polymers as a byproduct of their metabolism. Not every bioplastic biodegrades quickly, however, and some marketed as eco-friendly break down only in industrial composting facilities ③that reach conditions rarely found in a backyard compost heap or the open ocean. Critics point out that growing crops for bioplastic production can compete with food crops for farmland and water, ④complicating the assumption that a biological origin automatically makes a material more sustainable. Researchers are now exploring bioplastics made from agricultural waste and algae instead of dedicated crops, hoping to ⑤sidestepping this competition for land while preserving the benefits that first made bioplastics appealing.

Are you curious about capturing special moments around our school? The Photography Club is now ①looking for new members for this semester. We meet every Wednesday afternoon in Room 204, right after regular classes ②end. No experience is required, since senior members always teach the basics of ③using a camera. Each month, we choose a simple theme and take pictures together around the campus. At the end of the semester, we hold a small exhibition ④sharing our favorite photos. Members are also expected ⑤to bring their own camera or smartphone to every meeting. If you enjoy taking pictures or want to try something new, please visit our booth this Friday. Feel free to ask any current member if you have questions about joining.

As technology ①developing rapidly, many new jobs are appearing that did not exist a decade ago. Data analysts, for example, help companies make decisions ②based on huge amounts of information. Renewable energy technicians, ③who install and repair solar panels and wind turbines, are meeting the growing demand for clean power. Healthcare is expanding beyond hospitals, creating roles for specialists ④designing digital health tools for elderly patients. Experts predict that future workers will need ⑤to keep learning new skills throughout their careers.

On the first day of winter break, my friend Yuna and I sat in a cafe and talked about the new year ahead. Instead of ①making separate plans, we decided to write our goals together on one sheet of paper. Yuna wanted ②improving her English speaking, while I wanted to wake up earlier every morning. We agreed ③to text each other every night to report what we had done that day. Yuna, ④who noticed my short replies, called me instead of just texting. Because we supported each other through difficult moments, both of us ⑤successfully reached our goals by spring.

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.

Generation Z, typically defined as those born between the late 1990s and early 2010s, approaches shopping quite differently from previous generations. Having grown up with smartphones and social media, they research products extensively online before making even small purchases. Unlike older generations, who often valued brand loyalty above all else, many members of Generation Z prioritize a company's values, switching brands easily if one no longer matches their beliefs. They also tend to favor secondhand and resale platforms, viewing sustainability as an important factor rather than an afterthought. Peer recommendations shared through short videos frequently carry more weight than traditional celebrity endorsements. Businesses that fail to adapt to these preferences risk losing an entire generation of potential customers. Consequently, many companies now ___________.

The twenty-hour rule proposes that years of practice are not needed to become skilled at a new activity. Only about twenty hours of effort are needed to reach a useful level. Unlike theories claiming true mastery requires ten thousand hours, this rule targets a more modest goal. That goal is simple competence for everyday use. According to supporters, ___________, since a beginner has room to grow. Someone learning guitar can typically strum simple chords and follow a basic song within twenty hours of daily practice. Likewise, a language learner may soon order food or ask directions without years of formal study. Advocates emphasize that the twenty hours must be deliberate and focused, broken into short daily sessions rather than one long stretch. The hours should be aimed at fixing weaknesses rather than repeating what one already knows.

Because the two sums occupy entirely separate mental categories, the household feels no contradiction in treating them so differently. Consider a household that maintains two separate financial habits that, from a purely economic standpoint, appear difficult to reconcile. ( ① ) On one hand, the household carefully sets aside a fixed percentage of its income each month into a long-term retirement account, resisting any temptation to withdraw from it early. ( ② ) On the other hand, the same household carries a persistent balance on a credit card, paying a substantial interest rate simply for the convenience of short-term borrowing. ( ③ ) A purely rational calculation would suggest withdrawing a small amount from savings to eliminate the higher-interest debt, since the interest earned on savings is far lower than the interest owed on the card. ( ④ ) Yet the household rarely considers this option, since retirement savings are mentally categorized as untouchable while credit card debt is treated as a separate, ongoing obligation. ( ⑤ ) This example illustrates how mental accounting can lead to financial choices that persist despite being demonstrably suboptimal.

This simple comparison shows why learning the meaning of each symbol truly matters. Every plastic product carries a small recycling mark, but few students know what these marks mean. ① Each symbol contains a number that shows what material the item is made of. ② For instance, the number one usually stands for clear plastic bottles, while the number five represents thicker containers like yogurt cups. ③ Reading these marks is similar to reading nutrition labels on snacks, which tell you exactly what is inside. Without checking the label, you might buy something unhealthy by mistake. ④ Likewise, throwing plastic away without checking its mark can send a reusable item straight to a landfill. Some marks even show that a material cannot be recycled at all, so it must be sorted separately. ⑤ Therefore, taking a few seconds to check the mark before throwing something away makes recycling far more effective for everyone involved.

Critics note a further irony: when something goes wrong, such as a hacked exchange or a lost password, there is often no institution left to appeal to. Blockchain technology was originally promoted as a way to remove the need for trusted middlemen, allowing strangers to exchange value directly and verify transactions through a shared, tamper-resistant ledger. ( ① ) In theory, this design distributes power away from any single institution and toward the network as a whole. ( ② ) In practice, however, a small number of large players have come to dominate many blockchain networks. ( ③ ) They control enough computing power or currency to influence outcomes that were supposed to be decided collectively. ( ④ ) Whether decentralization can survive this concentration of power remains one of the technology's most unresolved questions. ( ⑤ )
