According to a 2023 report by a Chinese short-video platform,the views for book-related videos jumped by 65.17 percent year-on-year.As people become busier in competitive social environments,the brief literary explanations provided in short videos enable some to experience stories from a fresh perspective in fleeting moments.“I watch them on the subway,in a queue or before bed.Short videos combine text,images and expressions,providing a better experience than just reading text alone,” a man surnamed Zhang told Xinhua. The fearsome length and complexity(复杂性) of classics are also reasons why some people,especially teenagers,are turning to literature vloggers(video bloggers) for help.A Dream of Red Mansions is well-known for its detailed description of Chinese society,colorful characters and poetic language.It explores themes like family,society and human nature.However,these very qualities make the novel challenging for some students,who find it boring or even sleep-inducing(困倦的).“There are so many characters in the novel,which confused me a lot,” said 12-year-old Shao Xinyan from Hubei.“Some vloggers use a mind map to clearly show their relationship.” While reading with videos helps many people,some express different opinions and concerns.For Zhang Boren,a 13-year-old from Beijing,reading is a journey in which people form a personal connection with the text,not just absorbing facts.“Books that inspire my imagination,like fantasy adventures and historical stories,demand a deeper connection.Videos,although convenient,can’t fully present the small details of a well-written story,” said Zhang.Eighteen-year-old Wang Hongjie from Sichuan agreed,saying,“It may decrease readers’ ability to read independently and think deeply.” 1.Why do more people turn to short videos for classic literature? A.Short videos save time and offer vivid experiences. B.Classic books are often too out-of-date to be popular. C.They’re lacking in the motivation of reading completely. D.Video platforms provide more and more book-related content. 2.What makes A Dream of Red Mansions challenging for some students? A.Its unfamiliar themes and brief description. B.Its focus on ancient social culture in China. C.Its poetic language and various characters. D.Its unique writing features and target readers. 3.What is Zhang Boren’s opinion on enjoying classics via videos? A.Videos contribute more to inspiring imagination. B.Reading books increases readers’ independence. C.Reading books for readers is only to absorb facts. D.Videos are unlikely to contain all original details. 4.What can be a suitable title for the text? A.“Watch” the Classics B.“Update” the Videos C.“Approach” Literature D.“Play” with Vloggers B (2026江苏南京高一上期末) When we’re in trouble,we always turn to our parents for help.But would you like them to hear the conversations you have with your friends on the school playground or lunch queue?Social networking sites have become extensions(延伸) of the school hallways,so would you add your parents as “friends” and allow them to view your online activities and conversations with friends? In the past the generation gap included a technology gap,where children were up to date with the latest technology and parents were left behind,content to continue their day-to-day lives as they always had because they had no need to know more about technology.However,more and more parents are beginning to realize just how important social networks are in their lives.This realization has given many parents the motivation(动机) to educate themselves about social networking sites. These days many people are attracted to social networking sites because they can choose who they have around them.There’s also a certain amount of control over privacy(隐私) that we don’t get in real life.Sometimes we feel that privacy is violated(侵犯) when we must accept a “friend” request from a parent or family member. It’s a difficult choice whether or not to allow a parent to become a part of our online lives.On the one hand,we don’t want to “refuse” their request because that might hurt their feelings or make them feel you have something to hide.On the other hand,if you do accept,then you could have a sense of being watched and no longer feel free to comment or communicate the way you did before. A recent survey suggested that parents shouldn’t take it personally if their children overlook(忽略) their requests.When a teenager overlooks a parent’s friend request,it doesn’t necessarily mean that he is hiding something,but it could mean that this is one part of his life where he wants to be independent. Perhaps talking with parents and explaining would help soften the blow if you do choose not to add them to your friend list. 5.What is the passage mainly about? A.Privacy online. B.Parents’ friend requests. C.The generation gap. D.Social networks. 6.What can we infer from paragraph 2? A.Parents have realized the importance of social networks. B.Parents feel secure about their privacy online. C.Social networks successfully fill the generation gap. D.Social networks offer a chance for parents to communicate. 7.What may be the reason for teenagers to refuse a parent’s friend request? A.Their parents make negative comments on them. B.They hide something from their parents. C.They are unwilling to be watched by parents. D.Their parents tend to fall behind in technology. 8.What does the passage suggest doing if a teenager refuses a parent’s friend request? A.Blocking the parent from sending further requests. B.Ignoring the request without any explanation. C.Creating a separate account for family members. D.Discussing the decision openly with the parent.
