Building a career portfolio is a great way ①to track your growth throughout high school. A portfolio is simply a collection of your achievements, activities, and reflections. Start by ②choose a format, such as a folder, a notebook, or a digital file. Next, include items ③that show your interests and skills, such as club activities and volunteer work. For each item, write a short reflection explaining what you learned. A well-organized portfolio not only ④helps you apply for programs or scholarships, but it also ⑤helps you understand your own growth over time.

Strong summer sunlight can ①damage your skin if you are not careful. Ultraviolet rays are invisible light from the sun that ②causing sunburn, wrinkles, and even skin cancer over time. To protect your skin, apply sunscreen with a high SPF ③before going outside. Wearing a hat and sunglasses also helps ④shield your face and eyes from direct sunlight. Skin ⑤that has been damaged by the sun can take a long time to heal.

For the first week, she woke up early and ran ①happily, feeling proud of her new habit. However, after a few cold mornings, she began oversleeping, and soon she stopped running altogether, which made her feel ②confident about her progress. By February, she felt disappointed and believed she simply lacked willpower. They realized that running before sunrise in freezing weather had been too ③difficult to maintain. So Minji changed her plan and decided to run after school instead, when the weather was ④warmer and she had more energy. She kept running three times a week, and by spring, she had grown much stronger and more ⑤positive.

Heatstroke happens when the body's temperature rises too ①high and cannot cool itself down. This condition can be completely ②harmless if it is not treated quickly. Drinking plenty of water helps keep your body ③cool. Wearing light, loose clothing also helps ④release heat from your skin. If you notice symptoms such as dizziness, you should move to a shaded place ⑤immediately.

When people estimate the value of an unfamiliar product, they rarely rely on objective calculation alone; instead, they anchor their judgment to whatever numerical reference happens to be presented first, however ①arbitrary that number may be. This phenomenon exerts a ②disproportionate influence on price perception precisely because initial figures function as a kind of cognitive gravity that subsequent estimates struggle to escape. A shopper who first sees a jacket listed at $300 before it is marked down to $150 will likely judge the discounted price as an excellent ③bargain, regardless of whether $150 actually reflects the jacket's true worth. Retailers, well aware of this bias, frequently display a ④deflated "original price" beside a discounted one, not because the higher figure is meaningful, but because it recalibrates customers' expectations. Even professionals are not immune: negotiators who open with an extreme initial offer often secure more ⑤favorable final terms than those who begin with a moderate one.

Before making a purchase, most online shoppers now read reviews written by previous customers rather than relying solely on advertisements. These reviews, posted by people who have no financial connection to the seller, often seem more trustworthy than promotional claims. Research shows that products with a large number of positive reviews sell significantly more than those with few or no reviews at all. However, fake reviews written by paid writers or even automated programs have become a serious problem, undermining consumer trust. Platforms that fail to detect these fraudulent posts risk losing credibility with their users, who expect authentic opinions when making decisions. To address this issue, several review platforms have begun using artificial intelligence to identify suspicious patterns. Ultimately, the power of online reviews ___________.

Communication researchers have long studied why identical facts can produce very different public reactions depending on how they are presented. (A) Neither framing alone tells the complete story, so journalists who rely too heavily on either extreme risk distorting public understanding, and a balanced approach that honestly presents dangers while highlighting realistic solutions is far more likely to inspire lasting action. (B) When news outlets describe climate change primarily as a looming crisis, filled with images of disasters and warnings of irreversible damage, audiences often react with fear or, paradoxically, with hopeless resignation. (C) In contrast, when the same issue is framed as an opportunity, emphasizing innovative technologies and emerging green jobs, readers tend to feel more motivated to act and support policy change.

Whether or not a goal is motivating often depends on how clear it is. (A) For example, a student who simply decides to study harder often loses direction because the plan is too vague. (B) In contrast, a student who sets a clear goal, such as raising an English score by ten points, knows exactly what to do every day. (C) This is because a clear goal gives the brain an exact target to focus on, which makes progress easy to measure and keeps people motivated.

Climate change is not only a scientific and political issue but also an emotional one for many people today. (A) Teenagers and young adults tend to feel it most intensely, since they expect to live through many more decades of a changing climate than older generations do. (B) This emotional dimension, known as eco-anxiety, refers to persistent worry, grief, or fear that stems from awareness of climate change and its future consequences. (C) Fortunately, channeling this anxiety into constructive action, such as joining community environmental projects, can help restore a sense of control rather than deepen despair.

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.
