习题讲评(一)　2篇阅读理解＋1篇阅读七选五＋1篇完形填空 Ⅰ.阅读理解 A (2025·沧州模拟) At Countryside High School in Clearwater, Florida, 16-year-old Sage Waite is already taking a class in cybersecurity, and she'd welcome one that's in the works on cyber disinformation. “For the longest time, I didn't actually know what disinformation was，” said Waite, who's in the 11th grade.“There was always the idea that things could be wrong in what you're hearing and what you're being told.But the idea of misinformation and disinformation wasn't in my day-to-day.” This past year, she says, has been an eye-opener.“My friends and I definitely started looking into stuff more and doing more research after that，” she said. A new program on “digital literacy”， with a focus on topics like disinformation, is in the pipeline, thanks in part to Mike McConnell, who is now working to fight false information aimed at young people.“We need to understand this so we can appreciate what's happening to us, and be able to not only understand it, but also to navigate through it，” McConnell said.“That's what I call digital literacy.” McConnell is executive director of Cyber Florida, which is based at the University of South Florida in Tampa.The group works with kids throughout the state at universities, high schools, and even those in younger grades.Cyber Florida helped set up the cybersecurity program now being taught at many Florida schools.The new project, Cyber Citizenship, is even more ambitious.“We think if we can do this for Florida, we can spread it across the nation，” he said. The expanded program now in the works aims to make digital literacy something all Florida students get, at several grade levels, before they finish high school. There's no date yet for the cyber disinformation classes in Florida, but computer teacher Jason Felt says it can't come soon enough and he is ready to embrace it. “The Internet is a wonderful tool.It's connected us in a way that's never really been seen before.But it's a blessing and it's also a curse.” Teaching students the difference, he says, is a huge challenge. 语篇解读：本文是一篇说明文。文章介绍了Mike McConnell开展的数字素养课程项目。 1．What can we learn about the class that Sage Waite is taking from the first two paragraphs?

It's an awful circle.The more useful our phones become, the more we use them.The more we use them, the more we lay neural (神经的) pathways in our brains that lead to picking up our phones for whatever task is at hand — and the more we feel an urge to check our phones even when we don't have to. What we do know is that the simple distraction of checking a phone or seeing a notification (通知) can have negative consequences.This isn't very surprising; we know that, in general, multitasking does harm to memory and performance.One of the most dangerous examples is phone use while driving.One study found that merely speaking on the phone, not texting, was enough to make drivers slower to react on the road.It's true for everyday tasks that are less high-risk, too.Simply hearing a notification “ding” made participants of another study perform far worse on a task — almost as badly as participants who were speaking or texting on the phone during the task. It isn't just the use of a phone that has consequences — its mere presence can affect the way we think. In one recent study, for example, researchers asked participants to either put their phones next to them so they were visible (like on a desk), nearby and out of sight (like in a bag or pocket), or in another room.They were found to perform far better when their phones were in another room instead of nearby — whether visible, powered on or not. 语篇解读：本文是一篇说明文。文章主要介绍了成年人频繁使用手机的现象，以及人们频繁查看手机的负面影响。 5．What is the frequency, on average, for phone users to check their phones? A．Once every 3 minutes. B．Once every 4 minutes. C．Once every 5 minutes. D．Once every 6 minutes. 解析：选B　细节理解题。根据第一段第一句可知，成年人平均每天查看手机360次，再结合每天24小时，1 440分钟，可推知他们平均每4分钟查看1次手机。 6．What causes phone users' endless scrolling? A．The curiosity for friends' latest behaviors. B．The responsibility for the online safety. C．The desire for emails or social media information. D．The information for ensuring personal development. 解析：选C　细节理解题。根据第一段第二句可知，需要浏览我们的电子邮件或社交媒体动态导致我们查看手机。 7．What can we infer from paragraph 3? A．Simple distraction results in car accidents. B．Multitasking does no harm to intelligence. C．A notification “ding” can disturb our work. D．Answering a phone scarcely affects the driver. 解析：选C　推理判断题。根据第三段最后一句可知，“叮”的声音可以扰乱我们的工作。 8．Why is an experiment conducted in the last paragraph? A．To clarify multitasking does harm to memory and performance. B．To draw a conclusion that we shouldn't use phones much. C．To prove that it's dangerous to check phones while driving. D．To demonstrate the presence of a phone impacts our thinking. 解析：选D　推理判断题。根据倒数第二段以及最后一段可知，这个实验是为了论证仅仅手机的存在就会影响我们的思维。 Ⅱ.阅读七选五 (2025·泰安模拟)Having thousands of photos, songs and films available at our fingertips would have seemed amazing just a few decades ago, but how long will these files last for and be available? Could the digital data now put a time limit on our memories? __9__ The materials that phones and computers are made of can decay (腐蚀) over time. __10__ When digital data degrades, it can quickly make it impossible to open a file.Also, as formats and devices become out of date, it may become impossible to read files from previous decades. __11__ Large companies can still lose data.In 2019, social media platform MySpace admitted losing more than 12 years' worth of users' music uploads.The widespread use of streaming services for music, TV and film means that people no longer own the content that they watch and listen to; they just pay for the right to access it.If streaming companies decide to remove content, or go out of business, users will lose access. Licensing rather than buying content is an example of how our behaviour towards digital content has changed.__12__ This means that, in addition to the challenge of keeping our data safe, people have to consider what to preserve and what can be thrown away. So, what can we do? Technology writer Jack Schofield said that “data doesn't really exist unless you have at least two copies of it”. __13__ Probably more than one.Academic Paul Royster suggests that we should all take time to consider what content we personally believe is worth saving.Perhaps the answer is just to avoid digital altogether. A．It's necessary to store memories now. B．Digital memories might not last forever. C．Thus, this will impact the data they store. D．So it's important to back up what is important to us. E．Storing information in the cloud can also present problems. F．However, the quality of the data they store will remain unchanged. G．Another example is that we take far more pictures than people did in the past. 语篇解读：本文是一篇说明文。文章介绍了数字记忆可能不会永远存在的原因和解决措施。 9．解析：选B　上文提出问题：储存在电子设备上的 “数字记忆”能存在多久？下文则分析了数字记忆可能不会永远存在的原因。故B项“数字记忆可能不会永远存在”承上启下，符合语境。 10．解析：选C　上文提到，制作电子设备的材料会随着时间的推移而老化、被腐蚀。故C项“因此，这将影响它们存储的数据”承接上文，符合语境。 11．解析：选E　下文提到即使大公司仍有可能丢失数据，并具体举例展开说明，故E项“云存储也会出现问题”能概括本段主旨。 12．解析：选G　上文提到“授权而非购买内容就是我们对数字内容的行为发生变化的一个例子”。故G项“另一个例子是，我们拍的照片比过去的人拍得多”承接上文，符合语境。选项中的“Another example”与上文的“an example”相呼应。 13．解析：选D　上文提到杰克·斯科菲尔德的观点，为了确保安全，应拥有至少两份数据备份。故D项“所以把那些对我们来说很重要的东西进行备份是很有必要的”承接上文，符合语境。 Ⅲ.完形填空 (2025·蚌埠模拟)Growing up, Mychal Threets fell in love with reading at Fairfield Civic Center Library (FCCL) in California.Now, at age 33, he is the supervising librarian of FCCL and has gained a __14__ of more than 650,000 people who __15__ watching the videos he posts about libraries on social media.

I lived on that phone all summer with my face buried in its screen. I ignored my family and my surroundings. Being connected was more important than being present. So, you can imagine my displeasure when I learned what my dad had planned for our family vacation that year. “This year，” my dad said, “we'll be doing something special. We're going camping！” His excitement was met with a disappointed sigh. It wasn't my dream vacation because my mind was on my phone. I was so buried in the screen, in fact, that the first time I can remember truly looking up was when we drove across a bridge on the way to our campsite. I stared out the window and saw redwoods towering above us, their branches threatening to pierce (刺破) the blue sky. I saw a roaring river, with slivers of silky black water appearing between crashing white rapids. The air blowing into the car from the open windows was hot. But none of that mattered to me. The reason why I had looked up was for something far more serious. More shocking, my phone no longer had service. The last hour of the drive was increasingly tense. My dad announced that he had chosen a campsite that had no cell service, and that my phone would be useless until we returned home. I would be trapped in the forest for four days with no way to contact the outside world! I went through the full cycle of teenage emotions during the first day of the trip. I raged. I bargained. I begged. I changed from a depressive state to anger and back. I went to bed angrily that night. But when I awoke in the morning, something had changed. 注意：1.续写词数应为150左右； 2．请按如下格式作答。 Instead of burying myself in my phone, I focused on something else: my surroundings. 　 The next four days passed in a flash with many fun activities. 　 参考范文： Instead of burying myself in my phone, I focused on something else: my surroundings. I let the noise of the wilderness wash over me, animals and bugs creating a ruckus that was both loud and serene at the same time. My anger turned to peace, then a little interest and finally, excitement. Standing on the high campsite, I felt the weight of stress melt from my shoulders as I viewed the vast expanse that unfolded below me. The sight that met my startled eyes nearly took my breath away. For the first time, I thought camping in a place that had no cell service might not be so bad. The next four days passed in a flash with many fun activities. I hiked. I swam. I fished. My dad and I learned how to start a fire together after several false starts. We cooked together and I ate the sweetest marshmallows I had ever tasted. Dad told me stories of his life, stories I had never heard or perhaps I hadn't been listening. When the weekend came to an end, I realized I hadn't thought of my phone once. I hadn't felt the need to be connected to anywhere else. It dawned on me that what mattered most were the moments I was sharing with just my father and nature. 9 / 10 学科网（北京）股份有限公司 $$
