人教版物理八年级下册测试题 学生用卷期末素养综合测试(二)

班级 考号○ 订 ○ 内 期末素养综合测试(二)(满分100分,限时60分钟)一、选择题(每小题3分,共27分)1.(2022江西定南期中)体育活动中蕴含很多物理知识,下列相关说法中正确的是 ( )A.乒乓球被扣杀后飞向对方,说明力可以维持物体运动B.足球被踢出后仍能继续运动,是因为受到惯性力作用C.铅球落地后将地面砸了个坑,说明铅球受力发生了形变D.用力扣杀排球时手感到疼痛,说明力的作用是相互的1.答案 D 乒乓球被扣杀后飞向对方,说明力可以改变物体的运动状态,故A 错误;足球被踢出后仍能继续运动,是因为足球具有惯性,仍要保持原来的运动状态,故B 错误;铅球落地时将地面砸出了一个坑,说明力可以使物体的形状发生改变,故C 错误;用力扣杀排球时手感到疼痛,这个现象表明物体间力的作用是相互的,故D 正确。

2.【跨学科·地理】(2022河南淅川期中)如图所示,小雪用放在水平面上的两个实验装置来观察并研究大气压的变化,下列说法正确的是( )A.甲图中大气压变大时,玻璃管内的液面会上升B.乙图中大气压变小时,玻璃管内的液面会下降C.乙装置更能准确地测量出大气压的值D.两个实验装置均不受环境温度的影响2.答案 A 甲图是托里拆利实验,玻璃管内是真空,当大气压变大时,玻璃管内的液面会上升,能准确测出大气压的值;乙图中,外界大气压变小时,玻璃管内的液面会上升,瓶内封闭部分气体的压强受温度影响大,虽然能测出水柱的高度,但不知道容器内的气体压强,不能测出大气压的值。

3.在探究“杠杆平衡条件”实验中,在杠杆两侧挂上数量不等的钩码,移动钩码使杠杆在如图所示的水平位置平衡。

For over 100 years, libraries have played an important role in Americans’ education. But how are these book-filled buildings changing with the times? You may be surprised to find out.Benjamin Franklin famously founded (创建) America’s first lending library in 1731. But the public library system got its biggest development in the American history in the l ate 1800’s. Businessman Andrew Carnegie donated millions of dollars to help build free public libraries across the country. Between 1886 and 1919, Carnegie’s donations helped build 1,679 new libraries.Carnegie believed that libraries could offer the chances to Americans, young and old. He knew that the more libraries there were, the more people would have opportunities to read and use books, speeches and news.If you can easily find a public library in your community(社区), you’ll get more chances. After all, the United States has 9,225 public libraries. Today, libraries keep growing. Seven tenths of the libraries have free Internet. It provides much more information and opportunities to ask for jobs online.Libraries are also teaching kids about the fun of reading. The new program Read! Build! Play! adds reading into playtime. As kids listen to a book that is being read aloud, they use Legos (乐高积木) to build images(图像) from the story happily. Today’s libraries are always looking for creative programs to bring people into the library.Benjamin Franklin once said, “The doors of wisdom(智慧) are never shut.” As long as the doors of public libraries are open, what he said is most certainly correct!41njamin Franklin founded the first lending library in _______.A. 1731B. 1800C. 1886D. 191942How many public libraries have free Internet now?A. 2767.B. 6458.C. 9225.D. 1679.43The right order of the following statements is ______ .①The public library system in America developed fast.②The first lending library was founded.③ Libraries provide information and chances to ask for job online.④Libraries try to bring people into the library by using creative programs.A. ②①③④B. ②③④①C. ③④①②D. ①②③④44The last paragraph mainly tells us_________.A. libraries have played an important role in Americans’ educationB. public libraries in the US should never close the doorsC. the writer doesn’t agree with Benjamin FranklinD. libraries help people to open the doors of wisdom45The best title for the passage is _______.A. the libraries in the worldB. libraries and opportunitiesC. libraries teach kids to read and learn第II卷(共40分)一、单词拼写(共20小题,计10分)1 There was a(n) ____(通知) on the board saying the class had been cancelled (取消).2 In Europe, people eat with forks and_________(刀).3.We should care for the ________ (有残疾的) people.4 The bus stopped to let the p off.5.People in the western countries often eat with k and forks.6.Stop ________(扔) stones at that dog!7.

Minnie was the funniest dog that I'd ever seen. She looked like a sausage with thin curly hair. Her eyes always seemed surprised, and her tail looked like a rat's tail.She was brought to be put here because her owners didn’t want her any more. I thought Minnie had a sweet personality. “No one should judge her by her looks,” I thought. The doctor gave he r the necessary shots finally, I advertised Minnie in the newspaper. “Funny-looking dog, sweet personality, needs loving family.”A few days later, a young man called me. I warned him that Minnie was strange-looking. The boy on the phone told me that hi s grandfather’ssixteen-year-old dog had just died. A few minutes later, an old car stopped in front of the animal hospital. Two kids ran to the door. They brought the dog to their grandfather, who was waiting in the car. I hurried behind them. Inside the car, the grandfather held Minnie in his arms, she licked his face. It was love at the first lick. “She’s perfect!” the old man said.I was thankful that Minnie had found the good home. When I looked at the grandfather’s eyes, I found he was blind.根据文章内容回答问题。
