The immune system produces an almost limitless variety of antibodies, each ① shaped to latch onto one particular molecular target with remarkable specificity. Monoclonal antibody drugs harness this natural precision by cloning a single antibody-producing cell in the laboratory, ② generating an army of identical antibodies built to recognize one target, such as a protein on a cancer cell or a molecule driving an autoimmune disease. Because the antibody binds only to its intended target, these drugs tend to spare healthy tissue far more effectively than traditional chemotherapy, ③ which attacks any rapidly dividing cell regardless of whether it is cancerous. Manufacturing monoclonal antibodies remains far more complicated than producing a conventional small-molecule pill, since living cells must ④ cultivating in carefully controlled bioreactors for weeks before the antibody can be purified and prepared for use. This complexity keeps monoclonal antibody treatments considerably more expensive than most conventional drugs, a cost that continues ⑤ to shape debates over pricing and access.

Every time a smartphone connects to a cell tower or a Wi-Fi network, it quietly records a data point that can later ① be pieced together into a detailed map of where its owner has been. Most users agree to this tracking without ② reading the fine print, assuming that a single company's database poses little threat. The real danger, however, emerges when location data from multiple sources ③ combining. A pattern that reveals a person's home, workplace, and daily route can expose far more than any single app ever intended to share. Companies often argue that anonymized data cannot be traced back to individuals, yet researchers have repeatedly ④ shown that a handful of location points is enough to identify a specific person. As a result, privacy experts increasingly insist that location data ⑤ deserves the same legal protection as medical records.

Fast fashion refers to ①**cheap**, trendy clothing produced quickly and replaced almost as fast as it is bought. Because these garments are designed to be worn only a few times, huge amounts of fabric end up in landfills every year, and the dyeing process ②**pollutes** rivers near factories. In contrast, a ③**growing** number of brands are turning toward the circular economy, an economic model in which materials are reused, repaired, or recycled instead of being thrown away after a single use. For example, some companies ④**collect** old clothes, break down the fibers, and weave them into new fabric, while others let customers rent outfits for special occasions rather than buying garments they will barely wear. These approaches keep resources circulating within the system longer, ⑤**increasing** demand for raw materials. Therefore, shifting from a throwaway habit toward a circular one may be essential for making the fashion industry sustainable.

When choosing a future career, students often face a common question: should I follow what I love, or what I am good at? Passion can provide strong ①motivation, pushing a person to practice for hours without feeling tired. However, loving an activity does not always mean a person will become ②unskilled at it professionally. On the other hand, natural talent can lead to quick success, but without genuine interest, that success may eventually feel ③empty or exhausting. Career experts suggest looking for an ④overlap between the two instead of choosing only one side. Finding this balance takes time and self-reflection, but it often leads to a more ⑤satisfying and sustainable career.

Social psychologists describe a phenomenon called the bystander effect, in which individuals become less likely to help a victim as the number of witnesses ①increases. Each observer assumes someone else will step in, and this diffusion of responsibility leaves no one willing to act. Cyberbullying ②minimizes this problem, since a single humiliating post can be witnessed by thousands of people scattered across the internet rather than a few standing nearby. Anonymity ③intensifies the effect further, allowing silent observers to scroll past cruel comments without feeling accountable for their inaction. Some bystanders even worry that intervening publicly might make them the bully's next target, so they choose to remain ④silent instead. However, silence signals approval to both the bully and the audience watching the exchange unfold. Experts insist that even a single supportive comment can ⑤disrupt this harmful pattern.

Jian wanted to become a reader for years, but every time he picked up a thick novel, he felt overwhelmed and quickly closed it. His cousin, who had read dozens of books that year, told him about something called the two-minute rule. This rule states that a new habit should be shrunk to under two minutes, since a smaller starting point ___________. Instead of committing to a full chapter each night, Jian promised himself only to open a book and read one page.

Our school's volunteer club, Helping Hands, tries to _______________. Each month, students visit a nearby nursing home and spend an afternoon talking with elderly residents. For example, they read newspapers aloud or just listen to old stories from the residents. In addition, members collect used books and toys from classmates and donate them to a community center downtown. Some students feel nervous before their first visit, unsure of what to say to strangers. However, most discover that a warm smile works better than perfect words. Therefore, the club's real goal is not just finishing hours for a report card. Instead, it teaches members that caring for others grows into a lasting habit, like watering a plant daily. By the end of the year, many students say the club changed how they see their community.

Marketers have long recognized that perceived scarcity can dramatically increase a product's desirability, even when the item's intrinsic qualities remain entirely unchanged. A retailer who labels a product as "limited edition" or displays a countdown timer beside a discounted offer prompts customers to make hurried purchase decisions they might otherwise postpone or reconsider. Consumers who later reflect calmly on such purchases frequently discover that the item's actual usefulness fell well short of the ___________ they experienced at the moment of decision.

Good afternoon, everyone! Our town invites students to join a special tree-planting volunteer day next month. This event aims to restore a small forest damaged by last year's fire near the river. (A) Each participant will plant three young trees, guided by experienced forest rangers throughout the morning. For example, rangers will show volunteers how to dig proper holes without harming the tree roots. (B) Volunteers will meet at the community center at nine in the morning and travel together by bus. Please wear old clothes and shoes that you do not mind getting dirty during the activity. (C) In contrast, planting too shallowly often causes young trees to die within a few months. Therefore, careful instructions must be followed closely by every volunteer. Water and snacks, prepared by the town office, will be provided for free. Students interested in joining should register online before next Wednesday.

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.
