6 . Childhood Media Shaping Futures
Much of the media we consume during our formative years shapes us into the people we are today. Reflect on a particular piece of media from our childhood—perhaps it’s the TV show we eagerly awaited every weekend during visits to our grandmother’s house.
While they might have been restricted from social media accounts until a certain age, once given access, they tend to be more prepared. The media exposure of our generation has undoubtedly led to an increased maturation at younger ages.
Simply looking back at previous generations and the rate of consumption and processing of information that we experience every day, the effects of such are only beginning. As soon-to-be or current adults, we are already facing issues such as depression, anxiety, and delays in certain learning and social skills, just to name a few. Are we “more mature?” or are we overexposed and at risk for exceptional mental, physical, and emotional consequences?
In conclusion, childhood media consumption significantly influences our lives.
A.Such media doesn’t just entertain. |
B.You can easily pick out the differences among your siblings. |
C.As we journey through adulthood, it’s crucial to reflect on its impact. |
D.Media exposure during childhood impacts each child in distinct ways. |
E.Additionally, media have proven to have long-term effects on individuals. |
F.However, our mental and physical states may not be adequately equipped to handle it. |
7 . Hundreds of people die at sea every year due to ship and airplane accidents. Emergency teams have little time to rescue those in the water because the probability of finding a person alive falls dramatically after six hours. Beyond tides and challenging weather conditions, unsteady coastal currents often make search and rescue operations extremely difficult.
New insight into coastal flows gained by an international research team led by George Haller, Professor of Nonlinear Dynamics at ETH Zurich, promises to enhance the search and rescue techniques currently in use. Using tools from dynamical systems theory and ocean data, the team has developed an algorithm (算法) to predict where objects and people floating in water will go. “Our work has a clear potential to save lives,” says Mattia Serra, the first author of a study recently published in Nature Communications.
In today’s rescue operations at sea, complicated models of ocean dynamics and weather forecasting are used to predict the path of floating objects. For fast-changing coastal waters, however, such predictions are often inaccurate due to uncertain boundaries and missing data. As a result, a search may be launched in the wrong location, causing a loss of precious time.
Haller’s research team obtained mathematical results predicting that objects floating on the ocean’s surface should gather along a few special curves (曲线) which they call TRansient Attracting Profiles (TRAPs). These curves can’t be seen with our eyes but can be tracked from instant ocean surface current data using recent mathematical methods developed by the ETH team. This enables quick and precise planning of search paths that are less sensitive to uncertainties in the time and place of the accident.
In cooperation with a team from MIT, the ETH team tested their new, TRAP-based search algorithm in two separate ocean experiments near Martha’s Vineyard, which is on the northeastern coast of the United States. Working from the same real-time data available to the Coast Guard, the team successfully identified TRAPs in the region in real-time. They found that buoys and manikins (浮标和人体模型) thrown in the water indeed quickly gathered along these emerging curves. “Of several competing approaches tested in this project, this was the only algorithm that consistently found the right location”, says Haller.
“Our results are rapidly obtained, easy to interpret, and cheap to perform,” points out Serra. Haller stresses: “Our hope is that this method will become a standard part of the tool kit of coast guards everywhere.”

8 . The Role of Crowdfunding in Business Growth
Crowdfunding is a fundraising method that makes use of the power of the Internet and social networks. It involves raising small amounts of money from a large number of individuals or investors, typically through online platforms. These platforms connect entrepreneurs (创业者) with potential backers who contribute funds to support a specific project, business, or idea.
Types of Crowdfunding
Reward-Based Crowdfunding—Backers get a reward, such as a product sample or easy access, in exchange for their contribution. This model is popular for startups and creative projects.
Equity (股权) Crowdfunding—Investors receive shares or equity in the business in exchange for their funding. This model is ideal for small businesses looking to raise substantial capital and is subject to specific regulations.
Debt Crowdfunding—Entrepreneurs borrow money from backers and agree to repay it with interest over time. This model is similar to a loan and is suitable for businesses with a clear repayment plan.
Tips for a Successful Crowdfunding Campaign
Set clear goals: Define your funding goal, the purpose of the funds, and how you’ll use the money.
Persuasive story: Make an appealing and genuine story about your business. Explain why it matters and how backers’ contributions will make a difference.
Engage your network: Mobilize your existing network of friends, family, and professional contacts to support your campaign. Their initial contributions can build momentum (动力).
Transparency: Be transparent and honest about your project’s progress and any challenges you encounter. Backers appreciate honesty.
Fulfill promises: Once your campaign is successful, fulfill your promises to backers timely and communicate regularly.

D.Debt Crowdfunding is fit for businesses with a specific repayment schedule. |
A.carefulness | B.perseverance | C.frankness | D.optimism |
A.prefer Reward-Based Crowdfunding to Equity Crowdfunding |
B.draft an attractive story about the campaign based on real information |
C.realize their promises to backers on time even if the campaign is a failure |
D.compare the initial support provided by different existing contacts |
9 . Growing up in Ukraine, Vadim didn’t know what it was like to live in a safe, stable home. His parents were alcoholics who would often beat him. They’d even stuff him into a wine container, breaking his little body and leaving only a small opening at the top so he could breathe and see — but only just a little.
By the time Vadim turned 9, he was living in an orphanage (孤儿院). Unfortunately, as is the case with far too many little ones, his life only got worse there. Not only was he hurt, but he was placed in a room on the third floor, making it impossible to get downstairs in a wheelchair.
This left Vadim crawling up and down the stairs, an activity that was both physically and mentally exhausting. He’d often be late for meals. If the food wasn’t already gone by the time he arrived, other kids would steal from him.
Then, a chain effect began when some special folks visited the orphanage. They told him a story about a spiritual figure who advocated love and forgiveness. This conversation helped the 14-year-old find his faith and, in turn, he had more hope than he ever had before.
Today, Vadim is on longer the boy subject to fate. He is a father to his own kids, and his life couldn’t be more different or better. Over the years, he’s discovered a gift for expressing himself through art. This inspired Tim Tebow Foundation, an organization fighting for the most vulnerable (脆弱的) people around the world, to ask if he’d like to create a piece that represented what it looked and felt like for him to have gone from “darkness to light.”
The result? A truly remarkable painting that features Vadim, in his wheelchair, leaving behind his old home, including the wine container his parents stuffed him into. His new direction includes a beautiful forest full of fall leaves and bright light, showing the hope he is said to have found in the inspiring story.
1. According to the passage, Vadim’s parents treated him ________.A.abusively | B.forgivingly | C.thoughtfully | D.strictly |
A.Because his little roommates often did damage to his wheelchair. |
B.Because other children would take his meal without permission. |
C.Because he couldn’t use the wheelchair to go downstairs from a high floor. |
D.Because getting downstairs was demanding for him physically and mentally. |
A.an effective treatment for Vadim’s disability |
B.a series of positive changes occurring in Vadim’s life |
C.a sense of hope from the story of a spiritual figure |
D.a helping hand from Tim Tebow Foundation |
A.He admires the beauty and harmony of nature. |
B.He leads a miserable life with his own kids. |
C.He excels in delicate painting techniques. |
D.He says farewell to the past and harvests happiness. |
A. contrast B. instructed C. concentrating D. potential E. touching F. played G. better H. specialized I. spot J. follow K. tracing |
