初高中知识衔接题类型1 光学1. (折射定律)(2019蜀山区一模)光在水中的传播速度为空气中传播速度的34,光在玻璃中的传播速度为空气中传播速度的23.当光从空气中斜射入水中时,折射光线偏向法线;当光线从空气中斜射入玻璃中时,折射光线也偏向法线.大量实验表明,光的折射现象与光在介质中的传播速度有关.据此,当光线从玻璃中斜射入水中时,折射光线会________ (选填“偏离”或“偏向”)法线.2. (全反射)当光从光密介质(折射率大的介质)射向光疏介质(折射率小的介质)时,同时发生反射和折射,当入射角增大到某一角度,使折射角达到90°,折射光消失,只剩下反射光,这种现象叫做全反射,此时的入射角叫做临界角.如图,ABCD 是两面平行的透明玻璃砖,光线从界面Ⅰ射入玻璃砖,再从界面Ⅱ射出,回到空气中,如果改变光到达界面Ⅰ时的入射角,则下列说法正确的是 ( )第2题图A .只要入射角足够大,光线在界面 Ⅰ 上可能发生全反射现象B .只要入射角足够大,光线在界面 Ⅱ 上可能发生全反射现象C .不管入射角多大,光线在界面 Ⅱ上都不可能发生全反射现象D .以上说法都不正确类型2 力学3. (合力、分力)如图所示,当斜面上的木块匀速下滑时,木块受到重力G 、支持力F 支和摩擦力f,根据二力平衡知识可以判断出支持力F支与摩擦力f的合力方向是________.第3题图4. (胡克定律)在弹性限度内,弹簧的伸长量与所受的拉力成正比.将一根弹簧挂在支架上,弹簧长为10 cm,在下方用3.2 N 的拉力竖直向下拉弹簧,弹簧长度为12 cm,如果用9.6 N 的力沿竖直方向向下拉弹簧(没有超过测量范围),弹簧长度变为________cm.(不考虑弹簧自重)5. (动摩擦因数)重为100 N的木箱放在水平地面上,至少要35 N的水平推力,才能使它从原地开始运动.木箱从原地移动以后,用30 N的水平推力就可以使木箱匀速滑动,则木箱所受的滑动摩擦力为________;已知滑动摩擦力f与压力N的关系可以用公式f=μN表示,μ称为动摩擦因数,表示接触面的粗糙程度,则此时μ=________.6. (力的图示)(2019安徽黑马卷)力不仅有大小,还有方向,通过进一步的学习,我们可以将力用带箭头的线段表示.箭头指向表示力的方向,线段长短表示力的大小,箭尾表示力的作用点.如图所示,一个受到100 N浮力的物体悬浮在盐水中,请画出该物体所受到重力的图示.第6题图7. (合力、分力)(2019菏泽)阅读并计算:作用于同一点的两个力的合成符合平行四边形定则(线段的长短表示力的大小,箭头方向表示力的方向),如图甲、乙所示,以表示F1和F2这两个力的线段为邻边作平行四边形,这两个邻边之间的对角线就代表合力F的大小和方向.请计算丙图中F1和F2合力的大小为________ N.第7题图8. (加速度)物理学中,把速度的变化量与发生这一变化所用时间的比值叫做加速度.某辆电动汽车在一次刹车测试中,初速度为15 m/s,经过3 s汽车停止运动.若将该过程视为匀减速直线运动,则这段时间内电动汽车的加速度大小为( )A.3 m/s2B.5 m/s2C.12 m/s2D.15 m/s29. (位移)位移是用来描述物体位置变化的物理量,可以用从初位置到末位置的一条有向线段来表示,其大小等于该线段的长度.小明同学在一次游戏中按如图所示的路径从A点向正东方向走了2 m到达B点,然后由B点向正南方向走了3 m到达C点,再由C点向正东方向走了2 m到达D点,则在此过程中,小明同学运动的路程和位移大小分别是()第9题图A. 7 m,5 mB. 7 m,7 mC. 5 m,5 mD. 5 m,7 m10. (牛顿第三定律)(2019合肥50中二模)我们知道两个物体间力的作用是相互的,当把其中的一个力称为作用力时,另一个力就叫做反作用力.牛顿第三定律告诉我们:两个物体之间的作用力与反作用力总是大小相等,方向相反,作用在同一条直线上.如图所示,甲弹簧测力计右端固定,左端与A相连;木块A平放在木块B上,现水平拉动弹簧测力计乙使物块B在光滑的水平面上向左做匀速直线运动,当两弹簧测力计示数稳定时,甲弹簧测力计示数为F1,乙弹簧测力计示数为F2.(1)画出A所受的摩擦力的示意图;(2)请结合牛顿第三定律和平衡力的特点证明:F1=F2.第10题图11. (动能、势能)(2019合肥38中三模)已知物体的重力势能表达式为E P =mgh ,动能表达式为E k =12mv 2,其中m 为物体的质量,h 为物体距离水平地面的高度,v 为物体的运动速度,g =10 N/kg.如图所示,一小球从斜面底端以速度v 沿光滑斜面向上运动.不计空气阻力,小球在光滑的斜面上滑行时,机械能守恒.请推导:小球能运动到斜面上的最大高度h =v 22g.第11题图类型3 电学12. (电流)(2019安徽黑马卷)物理学上把单位时间内通过导体横截面积的电荷量叫电流.如图所示,一根横截面积为S 的长直导体棒,单位体积内的总电荷量是q ,当自由电荷以速度v 定向运动时,通过导体棒中的电流大小为________.第12题图13. (库仑定律)两个均匀带电小球之间的相互作用力,与它们的电荷量的乘积成正比,与它们的距离的二次方成反比,这种相互作用力叫做库仑力,公式为F =k q 1q 2r 2(k 为比例系数,r 为两个带电小球之间的距离).如图所示,在边长为a 的正方形的顶点A 和顶点C 处各放置一个电荷量为q 的带电小球,则两者之间的库仑力大小为_________.第13题图14. (电场、电场力)(2019安徽黑马卷)19世纪30年代,法拉第提出一种观点,认为在电荷周围存在电场,电荷之间通过电场传递相互作用力,如图所示,对于电荷A和电荷B之间的电场,下列说法中正确的是( )第14题图A. 电荷B在电荷A激发的电场中,受电场力的作用,自身也产生电场B. 撤去电荷B,电荷A激发的电场就不存在了C. 无论电荷A带哪种电荷,它对B产生的力的方向是相同的D. 电荷A激发的电场会对B产生电场力,电荷B激发的电场对A没有电场力15. (电场)在物理学中我们可以用电场线来形象直观地描述电场.电场线的疏密程度可以表示电场的强弱,电场线越密集的地方电场越强;电场线的指向可以表示电场的方向.如图所示为一个带正电的小球周围的电场线分布情况,则由图可知( )第15题图A .A 点的电场比B 点的电场强,A 、B 两点电场方向相同B .A 点的电场比B 点的电场强,A 、B 两点电场方向不同C .A 点的电场比B 点的电场弱,A 、B 两点电场方向相同D .A 点的电场比B 点的电场弱,A 、B 两点电场方向不同16. (电流、电场强度)(2019合肥38中一模)在比较电流强弱时,我们可以采用比值定义,把通过导体横截面的电量(Q )与时间(t )的比值定义为电流强度,简称电流,即I =Q t.国际单位制中,电量的单位库仑(C), 时间的单位秒(s),1 C/s =1 A .下列说法正确的是( )A. 通过导体横截面的电量越大,电流强度越大B. 通过导体横截面的电量所用时间越短,电流强度越大C. 电流的大小与导体本身有关,而与电荷的量以及通电时间都无关D. 灯泡电流0.2 A 的物理意义是每秒通过灯丝横截面的电量是0.2库仑类型4 磁学17. (电磁感应)(2019河南)如图所示,一轻杆左端挂一矩形塑料框A ,右端挂一外形相同的金属框B ,以O 为支点在水平位置静止.现使此装置竖直匀速下降,其下方有一方向垂直纸面向里的磁场区域(用“×”表示磁感线),当A 、B 框下端一同刚进入磁场时,发现杆沿逆时针方向转动,请你分析并推测此现象产生的原因:____________________________________________________________________________;若将磁场方向改为垂直纸面向外,重复上述操作,杆将沿________(选填“顺时针”或“逆时针”)方向转动.第17题图18. (磁场力)电荷在磁场中会受到力的作用,力的方向与磁场的方向和电荷运动方向有关.如图所示,一束电子自右向左从狭缝里射出,穿过磁场时受到磁场力的作用,向纸面内偏转,若将两个磁极对调,则电子束将向________(选填“纸面外”或“纸面内”)偏转.第18题图19. (洛伦兹力)运动电荷在磁场中受到的力称为洛伦兹力,我们可以依照左手定则判定:让磁感线从掌心进入,并使四指指向正电荷的运动的方向,这时大拇指所指的方向就是运动电荷在磁场中受洛伦兹力的方向.如图所示,abc三种粒子垂直射入匀强磁场(“×”表示磁场方向垂直纸面向里).根据粒子在磁场中的运动情况可判断出b粒子________;c粒子_______.(均选填“带正电”、“带负电”或“不带电”)第19题图20. (左手定则)左手定则可以用来判定通电直导线(带电粒子)在磁场中的受力方向,如图甲所示:让磁感线垂直进入掌心,使四指指向电流方向,大拇指所指方向即为所受力的方向.如图乙所示,将正负带电粒子不断射入A、B板间的强磁场,就会形成电源的两极,则( )甲乙第20题图A. B极板是电源的正极B. 带负电的粒子将向B极板偏转C.

It’s surprising to think about it. Now, China has more than 162 million Internet users, according to the China Internet Network Information Centre. This is the second highest number of user in the world after the United States. Today, 66%of Chinese “netizens (网民)” are teenagers. “They spend about thirteen hours every week online,” said Qian Hulin, an Internet expert. Doctor Song in Beijing Xuanwu Hospital said about 14% of Chinese netizens who are teens often lasted over ten hours to play online games.The main reasons why teenagers surf the Web are to search for information, to communicate with others and to have fun. On the Internet, teenagers can find out almost anything. And surfing the Web can help students with their homework and widen their knowledge.Li Dong, a teacher at No. 41 Middle School in Shijiazhuang, likes her students to use the Internet. “When we talk in class, students who surf the Net usually know more background information than the others,” she said.In addition, people can use the Internet to write letters or stories and send emails. Many teens keep in touch with their friends online. It is cheaper than phoning somebody far away and also much quicker.16. _______ has the most Internet users in the world according to the article.A. ChinaB. AmericaC. CanadaD. Russia17 . There are about _______ Chinese netizens to surf about 13 hours every week.A. 107 million oldB. 22.7 million oldC. 107 million youngD. 22.7 million young18 . Song said some teenagers continued _______ more than ten hours.A. playing online gamesB. searching for informationC. chatting with their friendsD. sending emails to others19 . Li Dong in No. 41 Middle School likes her students to use the Internet because she ______.A. thinks surfing the net can help students spend less time on homeworkB. thinks her students can get more background information than the othersC. wants her students to talk to her about their hobbies and interestsD. wants to know what her students do and think about at home20 . Which way is the cheapest and quickest to learn something about friends far away?A.Giving them a call.B. Going to see them.C. Writing a letter to them.D. Sending emails to them.Passage 2What will the house of the future look like? Could it have gardens on its walls, or a pool with fish for dinner? Architects (建筑师)believe that they are all possibilities. The only thing for sure is that the houses will be as green as possible.The tree houseMany architects in the world would like to build a “tree house.” Like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root”of the house is deep under the ground. It uses the soil to the home’s temperature.The Lizard houseLike a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.Meals at homeThis design is perhaps as much about the future of food production as architecture (建筑风格). It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.Learning from the pastLooking to the future isn’t the only way to be green. Sometimes, ancient techniques can also help cut down energy use. For example, a chimney (烟囱) can bea useful air conditioner because it is easier of hot air to flow out at the chimney.21. What is the best title of the passage?A. Green houses of the future.B. The greener, the better.C. How to build green houses.D. Changes of the houses.22.We can heat water, produce electricity or create fresh air for the home .A. with the root of a leaf.B. with the energy from sunlight.C. with the soil under the groundD. with gardens on its walls.23. What will happen to the cover of the lizard house when it’s in the bright sun?A. It will take in light.B. It will produce energy.C. It will turn dark.D. It will turn white.24. The passage seems to tell us that meals at home in the future .A. will be more delicious.B. need more cooks.C. cost as much as possible.D. will be greener.25. A chimney can be a useful air conditioner but it used to cause .A. pollution.B. accident.C. noise.D. techniques.Passage 3What might the future be like? Here are some predictions: things to come, things to go.The Spring Festival, the most important Chinese holiday when everyone returns home, has caused headaches for millions of Chinese. More than 2 billion people travel at the same time, making getting travel tickets and the journey difficult. But in 28years, Spring Festival travel may not be a problem at all. China plans to build more than 120,000 kilometers of railway and a fast transportation network that will serve 90% of the population by 2020. And because most of China will be cities, people will not have to go to other places to find a job, so it will no longer be a problem.Newspapers will come to an end in 2043. In the future, digital newspapers will be sent to personal web tools through Internet. Readers can discuss topics with journalists and editors. Information will move faster.Oil is running out faster than expected. But scientists have found something else for oil as fuel. Coal, natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy.Schools will go electronic. Computers will be important and popular among the students. Everything will be in the computer and students will not need to bring books to school. They will find information on the Internet. A computer will be the students’ library, schoolbag and connection to the outside world. There will be robot teachers, they will check homework on computers and communicate with the students’ parents through e-mail. And school buses will be like spaceships, comfortable and safe.26. More than 2 billion people have a hard time returning home during ______.A. Christmas DayB. National DayC. the Spring FestivalD. the Mid-autumn Festival27. The newspapers will disappear __________ .A. in 28 yearsB. by 2020C. by 2053D. in 31 years28. _______ is not mentioned in the passage as sources of energy.A. CoalB. WindC. Nuclear power(核能)D. Water29. From the passage we can know _________ in the future .A. the Spring Festival travel may still be a problemB. 90% of the population will live in the cityC. robot teachers will check homeworkD. readers can discuss topics with each other through Internet30. What’s the main idea of the last paragraph? .A. Schools will go electronicB. Computers will be importantC. There will be robot teachersD. School buses will be like spaceships三、完形填空。

一、现代文阅读(本题共6小题,20分)气(一)现代文阅读I(本题共3小题,10分)阅读下面的文字,完成1~3题。

材料一:汉字变形表意的现象古已有之,大约肇始于变体字的产生。

变体字是指通过改变某一个字的字形来表意的汉字。

改变字形的方法主要有两种:一是增减笔画表意。

如表示半木的“片”,取自“木”的篆文字形右半。

二是改变字形方向表意。

如表示不可之义的“叵”的字形是反写的“可”。

这种变体字可以说是后人利用汉字变形来表意的雏形。

之后,后人在景观中增添变形后的汉字,以达到加强汉字艺术表现力和表达某种寓意的目的。

例如,泰山上有一块摩崖刻石,刻着清光绪年间刘廷桂书写的“虫二”二字,是“风月”二字的变形,“虫”字由“风”字的繁体“風”省去声符“凡”而来,“二”字省掉了“月”字的外边轮廓,寓意“风月无边”。

汉字的结构由部件组合,横、竖、撇、点、折等笔画构成部件,部件与笔画的变化也会影响字义。

例如,秦皇岛山海关牌匾上的“天下第一关”五个大字中,“第”字写作“第”,“第”在《说文》中被释为“草也”,《集韵》有“一曰卉木初生叶儿”,这里借用“第”来表达谦逊的态度。

在汉字发展演变几千年后的今天,我们仍能见到将汉字和图画紧密结合的景观变形字。

例如,浙江杭州的城市形象标志就是“杭”字的变形。

“杭”在上古也有航渡义,与“航”相通,后来专用“航”指乘船济渡,遂使“杭”“航”成为古今字。

山东省潍坊市2023-2024学年度初高中衔接学科素养考试语文试题及答案解析

山东省潍坊市2023——2024学年度初高中衔接学科素养考试语文试题及答案解析一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成1~5题。

①从根本上说,诗歌的欣赏活动,凭借语言这种无所不在的符号来进行。

从符号再返回丰富的世界中来,这是一种再创造。

再创造的主要方式是想象活动。

诗人通过想象创造出了诗的形象,读者通过想象正确地把握住诗人的艺术构思,并且丰富地再现诗人创造的形象。

②当我第一次读崔颢的《长干曲》的时候,由于想象的展开所获得的愉快,至今还记得。

这一首诗只有20个字:“君家在何处?妾住在横塘。

停船暂借问,或恐是同乡。

”整首诗不作任何描写叙述,但一个青年女子活泼、爽朗而又令人亲近的形象跃然眼前:长江上两舟相逢,一个船家女,主动打问迎面而来的男子家住何处,是哪里人,她不等对方答话,又立即作了自我介绍。

后两句,可以理解为女子的自语,或理解为她因自己的热情主动而显得唐突,想极力掩饰自己的羞窘:“停船相问,别无他因,也许你我是同乡……”长江滔滔,两舟邂逅,一对青年男女的友好相遇所引起的新鲜与亲切之感,通过读者自由的想象得到了显现。

这是想象在欣赏中的作用,因此,我认为欣赏是一种再创造。

③但是,也不可对诗的欣赏存在着不切实际的奢望,以为读诗可以“创造一切”,因而也可以洞悉一切。

诗不可能把什么都告诉我们,特别是由于它不可能详尽地叙事。

交代情节、描写人物不是诗的擅长,诗的特点在抒情。

作为读者,希望通过诗的形象产生感情上的共鸣,不单是了解诗人的感情活动,而且寄托自己的情思,或者重温自己曾经有过的情感的经历。

这就是诗的欣赏上的再创造。

④为了克服欣赏上的困难,要做的一件事,是把诗中所提供的东西“泡”出来。

就是说,要把诗人由繁复的生活现象加以高度精炼的东西,还原到它原先的状态。

如臧克家《老马》诗中的句子:总得叫大车装个够,它横竖不说一句话,背上的压力往肉里扣,它把头沉重地垂下!⑤这里写的是老马,但欣赏时,可以放开来想象它的寓意——诗是鼓励这么做的——我们相信:诗人写的是不胜重负的老马,心中要说的是他对于生活在皮鞭和奴役之下的劳苦人民的同情以及对他们坚韧毅力的赞美。
