Custom Gene Therapy Saves a Baby’s Life Doctors saved a little boy with a rare disease by fixing a tiny mistake in his DNA.They built a treatment just for him,like fixing a printing mistake in a very long book.His body healed.This could lead to cures for thousands of other rare diseases. Rice That Loves Hot Weather Chinese scientists found a gene called QT12 that helps rice survive hot nights.When added to regular rice,it helped the rice produce 78% more food during high temperatures.As the planet warms,this discovery will help farmers grow enough rice to feed millions of people. AI That Reads Your Mind (Sort Of) Scientists created an AI that turns brain signals into words using a simple cap with sensors.People who cannot speak,like stroke patients,can now communicate again.One woman said “I love you” to her family for the first time in 15 years. Super-Sticky Glue That Works Underwater Scientists created a powerful new glue that works perfectly underwater.They got the idea from a kind of rough little sea creature that sticks tightly to ships and rocks.The glue is so strong that it could change underwater repairs,medicine,and more. 1.What effect does QT12 have? A.It warms the planet. B.It increases rice production. C.It cures rare diseases. D.It makes farming sustainable. 2.Which discovery best shows that scientists sometimes learn from nature? A.Rice That Loves Hot Weather. B.AI That Reads Your Mind (Sort Of). C.Super-Sticky Glue That Works Underwater. D.Custom Gene Therapy Saves a Baby’s Life. 3.What do the four discoveries have in common? A.They all pay attention to physics. B.They all help fix body problems. C.They all solve real-world problems. D.They all depend on AI technology. B (2026湖北襄阳高二下期中) In the digital era,where social media floods with ceaseless sharing,26-year-old illustrator Lina from Hangzhou stands as a striking example.She regularly posts artworks and travel snapshots on Instagram but seldom replies to comments or engages in private conversations.“I love sharing fragments(碎片) of my life,yet building deep connections with strangers feels emotionally exhausting,”she admits.Lina’s attitude represents a growing trend among today’s youth:light socializing,a pattern that prioritizes self-expression over intensive emotional bonds in the virtual world. Sociologist Min Li observes that social media,once a hub(中心) for developing relationships,has changed into a “self-showcase” platform for the younger generation.Instead of seeking active interactions,they share content like scenic photos or daily routines,with little expectation of feedback.Actions such as casually unfollowing,blocking strangers or using 24-hour disappearing posts show their wish to avoid burdensome “emotional labor” from shallow virtual ties.This shift comes from their desire to escape overwhelming pressure from empty digital interactions. While critics dismiss light socializing as a sign of “emotional coldness”,it actually reflects a thoughtful adaptation.Psychologist Lu Chen argues that by embracing this approach,young people regain control over their online space—sharing freely without the anxiety of meeting others’ expectations.Even social platforms have evolved to meet this need:many now offer “silent modes”,such as hidden interaction records and one-way posting features,acknowledging the widespread acceptance of light socializing. In a world tightly bound by digital connections,light socializing strikes a delicate balance between self-expression and privacy protection.It is not a refusal of social bonds but a wise pursuit of healthier,more autonomous online engagement.This trend shows the younger generation’s maturity in safeguarding their mental well-being,representing a forward-looking and thoughtful approach to modern social interactions. 4.What does Lina do on social media? A.She illustrates her artworks. B.She shares her trips and comments. C.She posts but skips deep chats. D.She focuses on building deep bonds. 5.According to Min Li,what has social media become for young people now? A.A tool to seek virtual ties. B.A platform for personal display. C.A space to reduce pressure. D.A center for deep relationships. 6.Why does the author mention “silent modes” in paragraph 3? A.To prove platforms ignore youth needs. B.To criticize the design of social media. C.To suggest users limit their screen time. D.To show the new practice gains recognition. 7.What does the author imply about the younger generation’s social approach? A.They are actively seeking mental health. B.They are sensitive to others’ feelings. C.They prefer traditional social relationships. D.They lack the maturity to interact online. Ⅵ.七选五 (2026山东济南二模) Why struggle with an essay when AI can generate one on your behalf in seconds?Why personally respond to an email when AI can instantly produce automatic replies filled with all the typical greetings and talking-points?　1　 Nevertheless,the ease is not necessarily a good thing.Writing still can’t be replaced even in the AI-driven era.  Writing serves as a fundamental cognitive(认知的) exercise through which we realize what we truly understand,acknowledge the limits of our knowledge,and develop structured reasoning.More crucially,it is precisely by the very act of writing that we individuals ultimately make new sense of the world around us and arrive at a deeper understanding of who we are.　2　  Paul Graham,a well-known computer scientist,once observed,“Good writers do not simply think and then record thoughts casually.　3　” Writing helps us generate ideas we have never had before.  Another critical but often overlooked function of writing is the compression(凝练) of ideas.　4　 When done poorly,this process loses precious insights.When done well,it generates the insights and removes the unnecessary parts.Compression requires thinking,which is one reason why writing is so difficult.  AI can write for us,but it won’t help us learn to think or understand a problem in depth.And we need in-depth comprehension to solve hard problems.A world of common thinking available on demand will encourage people to outsource their thinking and reward people who don’t.　5　 Original thinking will only become more valuable in the future.  A.It bridges the gap between ideas. B.Many people depend heavily on AI. C.AI has made writing surprisingly effortless. D.They always uncover insights in the act of writing. E.Those who can think and write independently will stand out. F.This journey of self-discovery is in essence a vital form of learning. G.Writing requires us to keep to the point and organize our ideas logically.
