物理（第一期）知识综合1.（2024遂宁2题）2024年4月25日，我国使用长征二号F遥十八运载火箭成功将神舟十八号载人飞船发射升空，此次发射中涉及的物理知识说法错误．．的是（）A.火箭上升过程中，以火箭为参照物，它搭载的飞船是运动的B.地面控制中心通过电磁波向飞船传递信息C.火箭发射应选用热值较大的燃料D.火箭发动机是将内能转化为机械能的装置【推荐地区：安徽、云南、甘肃】【参考答案】1.A【解析】火箭搭载飞船升空，在上升过程中，火箭与飞船之间的相对位置没有发生变化，因此以火箭为参照物，飞船是静止的，A错误；地面控制中心与飞船是通过电磁波传递信息的，B正确；相同质量的燃料完全燃烧时，热值较大的燃料可以释放出更多的热量，因此火箭应选用热值较大的燃料，C正确；火箭发动机工作时，将燃料的内能转化为火箭的机械能，D正确。

故选A。

电路设计2.（2024重庆B卷6题）家用电动窗帘的电路主要由电源指示灯L和电动机○M组成。

先闭合开关S1，电源指示灯L亮；再闭合开关S2，电动机○M工作拉动窗帘。

当S1断开时，电动机○M不能工作。

如图所示电路中符合要求的电路是（）A B C D【推荐地区：安徽】【参考答案】2.B【解析】根据题意可知，电源指示灯L和电动机○M可以各自独立工作，这说明该电路为并联电路；开关S2只控制电动机○M，这说明S2与电动机○M串联；开关S1断开时，电动机○M不能工作，这说明S1在干路上，由此可知，B正确，ACD错误。

故选B。

滑轮组相关计算3.（2024遂宁9题）修建房屋时，质量为60 kg的建筑工人使用滑轮组提升建材。

他用竖直向下的拉力在15 s内将重为480 N的建材匀速提升了3 m，每个滑轮重20 N，不计滑轮摩擦和绳重，g取10N/kg。

下列结论正确的是（）第3题图A.工人拉动绳子的速度为0.2 m/sB.工人对绳子拉力的功率50 WC.此装置的机械效率为96%D.若工人脚与地接触面积共400 cm2，则他对地的压强为1.5×104Pa【推荐地区：安徽、云南】D错误。

On screens usually appears a dragon. It’s a symbol of light, growth and life-giving water.It also stands for nobility and power. The peacock, a beautiful bird,can be seen on screens,too. It’s a symbol of everlasting life. Beautiful flowers,which mean wealth and good luck,are also chosen as a popular design of the pingfeng. All the designs carry people’s beautiful wishes.Behind the pingfeng lies an interesting story. In the past, the unmarried daughter of a rich family was not supposed to see or be seen by men except her father, brothers or very close male cousins. When an admirer paid a visit,however, she might take a secret look at him from a screen behind which she would be completely hidden. Her father would discuss poems with the young man and ask him to create one. If the daughter and her father were satisfied with the young man’s poem and his looks, she might agree to take him as a husband.Today the pingfeng is back in fashion for its beauty and its practical(实际的) use as furniture. Acting as a moving wall or divider, it can be the perfect match(相配) for modern sofas and walls, which adds style to them.The pingfeng is more than beautiful furniture.1.What was the pingfeng used for at the very beginning?A. Protecting people from wind.B. Dividing a room.C. Making a room beautiful.D. Hiding a person.2.Which design is a symbol of wealth and good luck?A. The dragon.B.The peacock.C. The water.D. The flowers.3. How does the writer develop his idea in Paragraph 2?A. By telling a story.B. By giving examples.C. By comparing differences.D. By explaining the result.4. What is the best title for the passage?A.The Practical Use of the PingfengB.A Beautiful Story of the PingfengC.Old Pingfeng in Modern HomesD. The Hidden Beauty of the Pingfeng【推荐区域：安徽、云南】【参考答案】1.A 2.D 3.B 4.DPassage 3（2023南充）Recently, a research on how a new virtual reality (VR 虚拟现实) experience educated children about the fire disasters (灾害)was done.The new VR experience was developed by the University of South Australia, hoping to educate children to learn how to be safe in a fire.It presents a situation for children aged 10-12.In the situation,they are tasked to look after a friend’s dog just before a fire event begins. They take part in a set of problem -solving activities tohelp save and protect themselves and the dog.The findings showed that over 80% of children could calmly tell the advantages and disadvantages of different choices.They also learned to make wise decisions to protect themselves from a fire. Children thought it especially important and meaningful,because 91% of them didn’t have knowledge of fires at the beginning,and 67% had said that they were too young to make safety decisions in a fire.The researchers believed such VR experiences made it possible to engage,educate and empower the young.“As children born in modern times,they are interested in such technology and they can experience events in a real situation yet within the safe environment,”said Delene Weber, one of the researchers.“Well-designed VR can provide children with surprisingly valuable learning tools.” Meanwhile, because children have fewer life experiences,aren’t as physically strong,and are less likely to have learned much about fire safety,they’re often most at risk.However, the role that children play in the fire safety at their homes should not be underestimated(低估).“Children don’t need to be always waiting for help in disasters. With these VR experiences, we can make children understand the risks and realize they can help,” said Weber.1. What’s the purpose of the new VR experience?A.To describe children’s reactions to fire disasters.B. To teach children to save themselves in a fire.C. To introduce ways of avoiding a fire to children.D. To increase children’s interest in VR experiences.2.From the findings, what’s the children’s attitude(态度)towards the new VR experience?A.Doubtful.B. Worried.C. Uncertain.D. Supportive.3.Which of the following in the dictionary best explains the underlined word“engage” in Para. 3?A.①B.②C.③D.④4.From Para. 3,we mainly get to know the______of the new VR experience.A.developmentB.advantagesC.qualityD.introduction5.According to the passage,which of the following is TRUE?A.Children make no difference in the fire safety at theirhomes.B. VR experiences are mainly designed for children in highschool.C.Well-designed VR can offer children amazingly valuable learning tools.D.91% of children believed they weren’t old enough to make safety decisions.【推荐区域：安徽、河北】【参考答案】1.B2.D3.A4.B5.CPassage 4（2023重庆B卷）Most people remember their childhood by looking at old photos or videos. But for some, they choose to remember it by making models of their old homes where they grew up.Du Yi,a Chinese miniature artist, used to make models of historic buildings. One day,a friend asked him to make a model of his old home in the countryside. He thought it was meaningful, so he helped. After he posted a short video online, it went viral. He won thousands of followers. Today, he has over 200,000 followers online.Du often makes the miniature(微缩模型) house 30 times smallerthan its real size. It usually takes him one to two months to make a model with the pictures provided by customers. Hundreds of small pieces and about 50 different materials,including wood, paper, and materials straight from nature are used.He often visits the villages to take a closer look at the details.He can spend the whole week studying one building, trying to understand the story,shapes and colors.“I have to be very careful about the details. If they are good, the work will come to life,”Du says. His miniature houses are sold at a starting price of around 20,000 yuan.“When I first saw the model of my old home, it took me back to my childhood. Grandfather taught me how to farm and make toys from things around us,”says Hao Wei,one of Du’s customers.When a skillful hand meets the need of people, a good business starts.1. How do most people remember their childhood according to the passage?A.By taking new photos.B. By watching TV.C.By looking at old photos.D. By visiting friends.2. What does the underlined word “viral”in Paragraph 2 mean?A.Difficult.B.Popular.C.Terrible.D. Important.3. What can we learn from the passage?A. Du Yi is believed to be the best miniature artist inChina.B. People who need miniature houses want to live in the past.C.Miniature artists make a lot of money by posting videos online.D. Du Yi’s excellent skills and hard work are helpful for his success.4.In which part of a newspaper can you probably read this passage?A.Sports.B.Health.C.Life.D.Nature.【推荐区域：安徽、云南、陕西】【参考答案】1.C2.B3.D4.C。
