11.小明对所学的一些物理量进行归纳,请你帮他补全空格处的内容,前两空的物理量是_____,_____,密度和比热容是描述_____的特性。
【答案】①.形状②.质量③.物质
【解析】
【详解】[1][2]物体属性是指物质本身所具有的特性,是描述物质的基本特征之一物体属性是指物质本身所具有的特性,是描述物质的基本特征之一。物体属性包括很多方面,例如:质量、体积、形状、硬度、颜色、温度等.
【答案】①.质量②.千克每立方米③.小于
【解析】
【详解】[1]物理学上把某种物质单位体积的质量叫做这种物质的密度。
[2]冰的密度为0.9×103千克/米3,读作0.9×103千克每立方米;表示的意思是每立方米冰的质量为0.9×103千克。
[3]冰熔化成水后,质量不变,但是水的密度比冰的密度大,根据密度公式 得,水的体积小于冰的体积。
【详解】压力的大小等于重力,为4N,方向垂直于接触面向下,作用点在接触面上。如图所示

(2*15)A_________________________________Chang’e is named after a goddess in ancient fairy tales, but few people know thatshe first appeared in the book Shan Hai Jing. It is thought to have been written duringthe late Warring States Period. Another figure in the book was Zouwu, a creature whofeatures (担任主演) in the movie Fantastic Beasts. Recently, the work and othersfeaturing ancient myths and monsters have inspired artists and authors to create, whichis a source of inspiration. Experts compared the book with the histories of ancient Greek.His World’s a StageActing was, is and always will be the first love of National Peking Opera Company’snew vice-president. Tian Lei has been working with the opera company for 10 years. Hehas spent a long time training acting there since he took Peking Opera as the most specialart. “Practicing here helps me feel closer to Peking Opera masters who once shone on thestage,” he says, “and that always gives me a sense of huge achievement when I perform.”Documentary About Dunhuang OnlineThe Master of Dunhuang, a documentary about artisans (工匠) and researchersworked on protecting and spreading Dunhuang’s centuries-old culture, will come out onTencent Video, ranging from restoration (修复) to research. The first episode features LiBo, a restoration expert, teaming up with his students to carry out an experiment. The second tale is about ZhangXiaoyang who works at Mogao Cave 254. Zhang is facing a fork in her career---to continue the research with an uncertain future or accept a new offer from a college.56. All the news above has something to do with __________.A. changesB. performanceC. cultureD. lifestyle57. According to Shan Hai Jing, we can know that __________.A. Zouwu was created in the movie series Fantastic BeastsB. ancient Chinese tales are similar to the histories of ancient GreekC. Chang’e was the first goddess appearing in the late Warring States PeriodD. many ancient myths and monsters offer inspiration to some cultural workers58. What would be the best title for the first news?A. Amazing Cultural ProductsB. Fantastic Chinese CollectionsC. Ancient Fairy Tales Get popularD. Ancient Work Inspires Modern Culture59. Tian Lei takes acting as his first love probably because __________.A. Peking Opera performance is the most special artB. the theater gives him a chance to keep practising operaC. it brings him a sense of self-satisfaction when he performsD. art acting makes it possible for him to meet masters he admires60. From the passage, we can know that __________.A. the documentary is going to be shown on Tencent VideoB. artists and authors have recreated the stories in Shan Hai JingC. Tian Lei spends all his time practicing and performing on the stageD. the documentary aims to introduce people who works in DunhuangBLast year I went to the Rio de Janeiro Carnival (狂欢节), and it blew my mind. It had been my dream to attend the famous carnival for many years, so I was excited. However, the moment I arrived, I was a little bit nervous because there were so many people on the streets. They say that five or six million people come to Rio during carnival time and about two million of them are on the streets on any given day. Luckily, I had a local guide, my sister’s friend Ronnie. He said he would take care of me and show me around at the carnival. He did not let me down.Well, the carnival is all about the samba (桑巴舞). It’s a style of music and dance which comes from Africa. Samba music is usually fast and exciting with a lot of drums and harmonic vocals (和声). It is the kind of music that you couldn’t help dancing to. And I was learning that as I followed Ronnie through the crowd.Ronnie had got us tickets for the samba Parade (游行) inside the Sambadrome where the top samba schools take part in the competition. But we still had a long way to go through the street parties. He said most people enjoy the carnival by making their own parties in the street.So, you must be wondering how the samba parade was in Sambadrome. ★. Ronnie and I never made into Sambadrome. We spent the day moving from one street party to another. There were more snacks, more drinks and lots of dancing. Do I regret missing the main parade? Not at all. I experienced the carnival like the locals, and itwas truly amazing.61. The underlined words “it blew my mind” in the passage probably mean __________.A. it made me tiredB. it brought me childhood memoriesC. it raised some questions in my mindD. it made me very surprised and excited62. After the writer arrived at the carnival, __________.A. she lost her wayB. she was too shy to danceC. she was received by a local guideD. she felt sorry for the crowded streets63. Why didn’t the writer regret missing the main parade?A. Because she met some amazing local peopleB. Because she made her own parties in the streetC. Because she celebrated the festival in a local wayD. Because the ticket for the parade was not expensive64. Which of the following sentence can be put in ★?A. I agree with youB. It’s really a good ideaC. Well, I’m afraid I can’t tell youD. But I have never heard of it before65. What would be the best title for the passage?A. An Amazing CarnivalB. An Unforgettable Street PartyC. A Story Behind the Samba ParadeD. Learning Samba in Rio de JaneiroCI grew up in the countryside of Poland. It’s an area where skiing is popular, but my family was poor. I couldn’t afford to ride the ski lift, so I used to hike up with the skis on my back. It turned out that this was good practice.K2 is nicknamed “savage (野蛮的) mountain”. You hear tragic stories: For every four people who reach the summit, one dies. I was too afraid to even think about skiing down it. Even the best ski mountaineers thought it impossible.But that changed after a training expedition (考察) to Broad Peak. I got a clear look at K2’sextremely large face, and it inspired me. Over time, my skills improved and, by 2017, I didn’t feel the fear anymore. I began preparations.Why attempt such a feat (壮举)? I love nature, and I love setting goals. To be the first to do it just adds to the challenge. Fear is an important part of life, but to ski down K2, I had to stop being afraid.At the base camp, I felt calm and prepared. There were no emotions or doubts--I just knew I could do it. But there were challenges. At the third base camp, 7, 000 meters up, my safety guy suffered severe back pain. We waited for 36 hours after he got better, and I decided to proceed. In total, it took about three days to reach the summit.For many climbers, getting to the peak of K2 would be the defining moment of their lives. For me, it was where the real challenge began. Skiing down a mountain demands patience and endurance (耐力).The most dangerous part was the Messner Traverse. It’s pure ice, up to a75-degree angle in places, with drops on either side. You need to keep your turns and movements smooth and confident. No one had challenged it before, so it was a relief to cross it.In total, going down the mountain took about seven hours. When I finally skied into camp, I was too tired tostand up.I am so proud of what I achieved. No one thought it could be done. It taught me the value of patience and that nobody else can make your dreams come true.66. From the first paragraph, we know that the author __________.A. was poor at skiingB. was interested in skiingC. lived in Poland where everyone liked skiingD. preferred hiking with skis on his back to riding the ski lift67. Paragraph 2 mainly talks about __________.A. how difficult it is to ski down K2B. why the author wanted to challenge K2C. how many mountaineers ever reached K2D. howK2 got the nickname “savage mountain”68. The underlined word “proceed” in paragraph 5 probably means __________.A. give upB. go onC. get upD. go back69. What are the best words to describe the author?A. Confident and honest.B. Patient and determined.C. Understanding and careful.D. Hardworking and helpful.70. From the passage, we can infer that __________.A. the author made full preparations but failedB. no one believed in what the author had doneC. the author was never afraid of skiing down K2D. the author’s positive attitude without fear leads to successPart TwoV.
