Ⅲ.主题语篇阅读 语篇解读　这是一篇说明文。美国国家航空航天局(NASA)与一家手机生产商合作在月球上创建4G网络，此项目面临挑战，对阿尔忒弥斯计划意义重大，助力人类长期驻月。 The partnership is helping to provide what could be the first steps for people’s long-term presence on other planets.While this seems like something out of science fiction，the reality is that a SpaceX rocket was launched later in 2024 and it carried a 4G network to the surface of the Moon.The lander，made by the US company Intuitive Machines，will put in this system on the Moon’s south pole and it will be remotely operated from the Earth. The 4G network which is being built by the cellphone producer’s Bell Labs and is essentially a network in a box，has to be strong enough to operate in the severe conditions of the lunar(月球的) environment. “The first challenge to getting a network up and running is having space-qualified cellular equipment that meets the appropriate size，weight，and power requirements，as well as being deployed(部署) without a technician，” Walt Engelund，deputy associate administrator for programs at NASA’s Space Technology Mission Directorate，told CNN. It is critical to be able to communicate via cellular connectivity for NASA’s Artemis program which hopes to return astronauts to the Moon this decade.Astronauts currently communicate with each other by radios but a more sophisticated system is needed. “Being able to communicate on the Moon is critical to Artemis—as critical as any other mission element like power，water to drink，and air to breathe，” said Engelund.“Eventually，this effort will help establish a lunar communications network that could give our explorers the ability to send scientific data back，communicate with mission control，and talk to their families，as if they were walking down the street on their cellphones.” 1.What are NASA and the cellphone producer doing together? A.Live streaming on Mars. B.Sending a rocket to Mars. C.Building a Moon 4G network. D.Making special phones for space. √ 细节理解题。根据第一段第二句“That’s because NASA and a cellphone producer are working together to set up a 4G cellular(蜂窝状的) network on the Moon.”可知，NASA和一家手机生产商正在合作建立月球4G网络。故选C。 解析 2.What makes the project challenging? A.The distance from the earth. B.The Moon’s severe conditions. C.The need for better technology. D.The lack of technicians on the Moon. √ 细节理解题。根据第四段中的“The first challenge to getting a network up and running is having space-qualified cellular equipment that meets the appropriate size，weight，and power requirements，as well as being deployed(部署) without a technician”可知，这里明确提到了没有技术人员进行部署这一难题，所以该项目具有挑战性的原因是月球上缺乏技术人员。故选D。 解析 3.What does the underlined word “sophisticated” in paragraph 5 mean? A.Advanced. B.Communicative. C.Educational. D.Scientific. √ 词义猜测题。根据画线词所在句“Astronauts currently communicate with each other by radios but a more sophisticated system is needed.”可知，此处将现在宇航员使用的无线电通信系统与将来所需的系统作对比，现在的系统相对简单，所以将来需要更先进的系统，sophisticated意为“先进的”，与advanced同义。故选A。 解析 4.What can be inferred from the last paragraph? A.The network is only for sending data back. B.Communication is as important as life support. C.The network helps with family calls on the street. D.Drinking and breathing are hard for the explorers. √ 推理判断题。根据最后一段第一句“‘Being able to communicate on the Moon is critical to Artemis—as critical as any other mission element like power，water to drink，and air to breathe，’ said Engelund.”可知，通信和生命支持一样重要。故选B。 解析 B Preschool children’s play involving(涉及) tablets is less imaginative compared to their play involving physical toys.This is shown in a new study by Uppsala University.The result goes against the long held belief that new technologies would make children more creative. 语篇解读　这是一篇说明文。文章主要讲述了一项新研究表明，学龄前儿童使用平板电脑玩耍相比使用实体玩具玩耍更缺乏想象力。 “Although the study is quite small，it shows that we should perhaps be careful about using touch screens with preschool children，” notes Robin Samuel at Uppsala University. During the study，almost one hundred play activities were compared in two groups of preschool children,2-year-olds and 4-to 5-year-olds.30 children at two preschools took part in the study during the preschool’s free play time，i.e.play without much involvement from teachers.Free play takes up about 57 percent of children’s time at preschool. The researchers recorded videos of the children playing.After that，they watched them and checked the patterns(模式) in the children’s play—what the children did when they played with tablets and when they played with physical toys such as toy bricks and dress-up clothes.The study showed that play involving tablets was more exploratory(探究的) but in short of simulation(模拟) and imagination，which may hardly leave children with the opportunity to experiment with new ideas. The courses for preschool，known in Swedish as Lpfo 18，state that preschool teachers must take responsibility for making sure that every child can use digital tools in a way that helps with development and learning.As a result，tablets are commonly used in the country’s preschools and are a part of many children’s everyday lives.Both educators and researchers have seen the opportunities afforded by new technologies. “Our results were not only clear but also surprising.We hope that our results are meaningful and helpful to preschool teachers，parents and others who stay with children and technology in day-to-day life.While there are possible learning mechanisms(机制) for exploratory play using digital devices，there should be an awareness(意识) that new technologies don’t always mean better，” notes Samuel. 5.What can be known about the study? A.It focuses on new technologies. B.It challenges the traditional view. C.It involved two groups with 30 children in each. D.It was done under the guidance of the teachers. √ 细节理解题。根据第一段中“The result goes against the long held belief that new technologies would make children more creative.”可知，这一结果与人们长期以来认为的新技术会让孩子更有创造力的观点背道而驰。即这项新研究挑战了传统观点，故选B。 解析 6.How did the researchers carry out the study? A.By introducing children to new play patterns. B.By interviewing preschool teachers and parents. C.By recording and comparing children’s play activities. D.By setting up different play environments and watching children’s behaviours. √ 细节理解题。根据第三段中“The researchers recorded videos of the children playing.After that，they watched them and checked the patterns(模式) in the children’s play...”可知，研究人员通过记录和比较孩子们的玩耍活动来进行研究，故选C。 解析 7.What’s Samuel’s attitude towards the preschoolers’ using digital devices? A.Supportive. B.Unclear. C.Uncaring. D.Doubtful. √ 观点态度题。根据最后一段中“While there are possible learning mechanisms(机制) for exploratory play using digital devices，there should be an awareness(意识) that new technologies don’t always mean better”可知，Samuel认为虽然使用数字设备进行探索性游戏可能存在学习机制，但我们应该意识到，新技术并不总是意味着更好，故他对于学龄前儿童使用数字设备持怀疑态度，故选D。 解析 8.What can be the best title for the text? A.Will Screen Time Kill Kids’ Creativity? B.Who Benefits More from Technology? C.Will Technology Become More Influential? D.What Kinds of Toys Are Proper for Kids? √ 标题归纳题。根据全文内容可知，文章主要讲述了一项新研究表明，学龄前儿童使用平板电脑玩耍相比使用实体玩具玩耍更缺乏想象力。A项“屏幕使用时间会扼杀孩子们的创造力吗？”为最佳标题，故选A。 解析 (2025·江苏南通高一上期末) As a senior in high school back in the 1980s，I was crazy about baseball.
