AThere are many weird sports that are present from around the world. From each region of the world, along with the very popular common sports, there are also those really popular but very weird kinds of sports.The Ultimate Test between Man and Horse:This indeed a very strange kind of sport that tests your stamina. You will learn how to be agiler while competing against a horse. This game originated in Welsh town of Llanwrtyd Wells. This sport really has to do with strength. You will require great agility and strength in order to take part in this. Marathon human contestantsare put to test against those mounted on horses. This is how the marathon testing takes place.Love Locked RaceThis is a sports event that was first introduced in Finland. This is all about a male competitor racing with a female in a certain way. There would be many obstructions and blocks on the way which would definitely bring you challenges. The person to win would have to finish the race without losing his female partner in the course of overcoming the obstacles even for once. This race takes place really fast and the obstacles are set that way.Toe sportThis is yet another weird sport that welcomes you to use your toes. This is quite the same kind of sport that you used to play as a child which involved toe wrestling. This has now been turned into a major sport that even has a World Toe Wrestling Competition. It first originated in a pub of Derbyshire.The locals took this sport with great enjoyment and then made this so popular that it soon had its own championship. The individuals who participate have only got to use their feet in locks but then this is tougher than it may sound.The Mud Pit Belly FlopThis is a kind of game where even the spectators get splashed in mud but in fact that is quite the fun. The very annual Summer Redneck Games in East Dublin brings about this game and brings about some of the greatest hubcap discus throws with it. This is also a great sport to show the strength and dexterity of your feet.1. Which sport requires couples to participate?A. The Ultimate Test between Man and HorseB. Love Locked RaceC. Toe sportD. The Mud Pit Belly Flop2. Which statement shows the popularity of the Toe Sport?A. It first originated in a pub of Derbyshire.B. The locals took this sport with great enjoyment.C. It has a World Toe Wrestling Competition.D. Even kids are fond of the sport.3. What kind of people are likely to take part in the Ultimate Test between Man and Horse?A. People with agility and strengthB. People with companionsC. Marathon runnersD. Horse ridersBThe evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly held image of unhappy teenagers locked in their room after endless family quarrels.An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past.” We were surprised by just how positive today’s young people seen to be about their families,” said one member of the research team. “They’re expected to be r ebellious(叛逆的) and selfish but actually they have other things on their minds; they want a car and material goods, and they worry about whether school is serving them well. There’s more negotiation and discussion between parents and children, and children expectto take part in the family decision-making process. They don’t want to rock the boat.”So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. “My parents are happy to discuss things with me and willing to listen to me,” says 17-years-old Daniel Lazall. “I always tell them when I’m going out clubbing. As long as they know what I’m doing, they’re fine with it.” Susan Crome, who is now 21,agrees.”Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I’d done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that.”Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenagers’ rebellion is not rooted in real facts. A researcher comments, “Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”4. The study shows that teenagers don’t want to ___A. share family responsibilityB. cause trouble in their familiesC. go boating with their familyD. make family decisions5. Compared with parents of 30 years ago, today’s parents___.A. go to clubs more often with their childrenB. are much stricter with their childrenC. care less about their children’s lifeD. give their children more freedom6. According to the author, teenage rebellion____.A. may be a false beliefB. is common nowadaysC. existed only in the 1960sD. resulted from changes in families7. Which title best gives the main idea of the passage?A. Discussion in family.B. Teenage education in family.C. Harmony in family.D. Teenage trouble in family.CThe days of the hunter are almost over in India. This is partly because there is practically nothing left to kill, and partly because some steps have been taken, mainly by banning tiger-shooting, to protect those animals which still survive.Some people say that Man is naturally a hunter. I disagree with this view. Surely our earliest forefathers, who at first possessed no weapons, spent their time digging for roots, and were no doubt themselves often hunted by meat-eating animals.I believe the main reason why the modern hunter kills is that he thinks people will admire his courage in overpowering dangerous animals. Of course, there are somewho truly believe that the killing is not really the important thing, and that the chief pleasure lies in the joy of the hunt and the beauties of the wild countryside. There are also those for whom hunting in fact offers a chance to prove themselves and risk death by design; these men go out after dangerous animals like tigers, even if they say they only do it to rid the countryside of a threat. I can respect reasons like these, but they are clearly different from the need to strengthen your high opinion of yourself.The greatest big-game hunters expressed in their writings something of these finer motives. One of them wrote.“You must properly respect what you are after and shoot it cleanly and on the animal’s own territory(领地)。

Everyone knows that the deeper you get, the more deadly the game becomes-and thebody count is rising. Since the game first started, ten rounds have taken place. The eleventh round is about to begin, and what happens in the game, stays in the game...1.What can we know about The Saints of Salvation?A.It's about the war among people on earth.B.The Olyix are defeated in the end.C.It belongs to The Salvation Sequence.D.It's the last novel of Peter F. Hamilton.2.What does Nine Hibiscus do to save Teixcalaanli Empire?A.He gives the alien a complete destruction.B.He lets someone negotiate with the alien.C.He fights against the alien bravely.D.He makes the alien face a threat.3.Where can the text be found?A.In a book recommendation.B.In an art magazine.C.In a biography.D.In a novelGuy Bryant never intended to be a father figure. But over the past 12 years, he’s housed more than 50 foster kids in his Brooklyn apartment.For decades, Bryant, 61, worked with teens aging out of New York’s child welfare system. His job was to find services that would make the transition (过渡) to living on their own easier. But he felt that what he could accomplish at the New York City Administration for Children’s Services office wasn’t enough. So in 2007, he decided to become a foster parent.In an interview last month, Bryant told Romario Vassell, 21, one of his foster children, that agreeing to care for him was definitely one of the best decisions he made in foster care. Bryant told Vassell that he was nervous when he took in his first foster child. He said, “I lived alone at that point, and he was a kid that nobody wanted to take because of his behaviors. He got in a fight and he appeared at my house.” Bryant said his family thought he was out of his mind for making such a big lifestyle change and wondered how Bryant would adjust.Bryant had been Vassell’s assigned case worker when they met. Bryart suggested that Vassell, then an untidy 18-year-old, consider foster care as an option to get out of the home lead shelter where he was staying.At first, Vassell was hesitant. “I didn’t know how foster care was.” he said.Since living with Bryant, Vassell now feels like he has a support network. “If I feel down and like I’m cornered, I have someone I can reach out to and talk to.” he said. “And that’s what I really love.”Bryant told Vassell, “Whatever you’ve learned from me, I want you to teach it to someone else. Because that’s what’s important to me.”4.What is the second paragraph mainly about ?A.The shift of teens’ life.B.An introduction of Bryant’s task.C.Bryant’s challenge as a foster parent.D.The reason for Bryant’s being a foster parent.5.How did Bryant’s family feel about his decision?A.Disappointed.B.Ashamed.C.Puzzled.D.Embarrassed. 6.What can we know about Vassell from the text?A.He is now living alone.B.He was Bryant’s first foster kid.C.He refused Bryant’s offer at first.D.He was instructed to pay kindness forward.7.What is the author’s purpose in writing the text ?A.To call for social care.B.To praise Bryant’s deeds.C.To tell the story of Vassell.D.To comment on Bryant’s life.Priscilla Ouchida’s “energy efficient” house turned out to be a horrible dream. When she and her engineer husband married a few years ago, they built a $100,000 three-bedroom home in California. Tightly sealed to prevent air leaks, the house was equipped with small double-paned windows and several other energy-saving features. Problems began as soon as the couple moved in, however. Priscilla’s eyes burned. Her throat was constantly dry. She suffered from headaches and could hardly sleep. It was as though she had suddenly developed a strange illness.Experts finally traced the cause of her illness. The level of formaldehyde gas in her kitchen was twice the maximum allowed by federal standards for chemical workers. The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting.The Ouchidas are victims of indoor air pollution, which is not given sufficient attention partly because of the nation’s drive to save energy. The problem itself isn’t new. “The indoor environment was dirty long before energy conservation came along,” says Moschandreas, a pollution scientist at Geomet Technologies in Maryland. “Energy conservation has tended to accentuate the situation in some cases.”The problem appears to be more troublesome in newly constructed homes rather than old ones. Back in the days when energy was cheap, home builders didn’t worry much about unsealed cracks. Because of such leaks, the air in an average home was replaced by fresh outdoor air about once an hour. As a result, the pollutants generated in most households seldom built up to dangerous levels.8.It can be learned from the passage that the Ouchidas’ house ________.A.is well worth the money spent on its constructionB.is almost faultless from the point of energy conservationC.failed to meet energy conservation standardsD.was designed and constructed in a scientific way9.What made the Ouchidas’ new house a horrible dream?A.Poor quality of the air inside.B.Poor quality of the construction. C.Gas leakage in the kitchen.D.The newly painted walls.10.The word “accentuate” (Para. 3) most probably means “________”.A.relieve B.accelerate C.worsen D.improve 11.Why were cracks in old houses not a big concern?A.Because indoor cleanliness was not emphasized.B.Because energy used to be inexpensive.C.Because environmental protection was given top priority.D.Because they were technically unavoidable.12.This passage is most probably taken from an article entitled ________.A.Energy Conservation B.House Building CrisisC.Air Pollution Indoors D.Traps in Building ConstructionThe regular world presented to us by our five senses—you could call it reality 1.0—is not always the most user-friendly of places. We get lost in unfamiliar cities; we meet people whose language we don’t understand. So why not try the improved version: augmentedreality (AR) or reality 2.0? AR technology adds computer-produced images (图像) on the real world via a mobile phone camera or special video glasses.Early forms of AR are already here. With the right downloads, smart phones can deliver information about nearby ATMs and restaurants and other points of interest. But that’s just the beginning. A few years from now the quantity of information available will have increased hugely. You will not only see that there’s a Chinese restaurant on the next block, but you will be able to see the menu and read reviews of it.This is where the next revolution in computing will take place: in the interface (界面) between the real world and the information brought to us via the Internet. Imagine bubbles floating before your eyes, filled with cool information about anything and everything that you see in front of you.Let’s jump ahead to ten years from now. A person trying to fix their car won’t be reading a book with pictures; they will be wearing a device that projects animated 3-D computer graphics onto the equipment under repair, labelling parts and giving step-by-step guidance.The window onto the AR world can be a smart phone or special video glasses. But in ten years’ time these will have been replaced by contact lenses (隐形眼镜) with tiny LEDs, which present something at a readable distance in front of the eye. So a deaf person wearing these lenses will be able to see what people are saying.The question is, while we are all absorbed in our new augmented reality worlds, how will we be communicating with each other?13.What does the text mainly talk about?A.The next information technology revolution.B.Early forms of augmented reality technology.C.The differences between reality 1.0 and reality 2.0.D.The relationship between people living in reality 2.0.14.What does the underlined word “it” refer to in Paragraph 2?A.The menu.B.The block.C.The revolution.D.The restaurant.15.What are tiny LEDs used to do?A.Protect people’s eyes.B.Show text and images.C.Warn users of dangers.D.Replace video glasses.16.What’s the author’s attitude towards AR technology?A.Doubtful.B.Disapproving.C.Favourable.D.Ambiguous.二、七选五Master Your DeadlinesThe struggle begins in high school, sometimes earlier. Deadlines, and lots of them, start to pile up. At college, the pressure sometimes leads to last-minute rush and unsatisfactory work. At work, failing to meet deadlines can easily get you fired. ___17___ Here are a few best practices.▪Assign deadlines to what matters.If the task isn’t of high importance, don’t set a specific deadline. In this way, you are able to keep it on your radar for a while without feeling pressured. ___18___ This will provide just enough pressure to ensure you get it done.▪ ___19___Set a personal deadline for yourself a day or two before the actual deadline. ___20___ If you’re working with a group of people, add in even more time to account for potential follow-ups and the need for approvals.▪ Keep communicating.___21___ This means letting others know when something is taking longer than expected, when a delivery didn’t come in, when a client is not providing the necessary information, etc. Although it may feel embarrassing to admit that something is not on schedule, being honest is much better for relieving your stress.A.Plan for flexible hours.B.Finish your project as early as possible.C.But if an activity is urgent, set a deadline immediately.D.In this way, you’ll never have to stay up late and feel stressed.E.But handled properly, deadlines can actually improve productivity.F.Whenever you feel challenged to finish work on time, communicate.G.So if anything takes longer than expected, you can still wrap it up and submit it on time.三、完形填空I was shopping at the local food store and started chatting with the cashier about my three - year - old daughter’s favorite food. It was applesauce (苹果酱). The cashier warmly ___22___ me some wonderful brands. She smiled and then told me that her son who was one year old also loved ___23___.

Now, with my three - year - old daughter to look after, I am able to stay at home and really ___28___ each minute.The ___29___ then sadly told me that she didn’t see her son much because she did two ___30___ and that she wanted to be able to give him the best of everything and ____31____ money so that someday her son could go to college and be ____32____ This made me____33____. On one hand, I understood what she meant, but on the other hand, I knew how much more ____34____ time with kids was against jobs and money.I wanted to do something nice for her.

所用的时间为D.质子从b运动到c,电场力做功为4eV考点:电势;电势差与电场强度的关系.专题:电场力与电势的性质专题.分析:在匀强电场中,沿着电场线方向每前进相同的距离,电势变化相等;依据电场线与等势面垂直垂直画出电场线,依据W=qU计算电场力做的功.解答:解:A、在匀强电场中,沿着电场线方向每前进相同的距离,电势变化相等,故φa﹣φd=φb﹣φc,解得:φc=16V,而φa点电势为20V.则c点电势低于a点电势.故A错误;B、设ad连线中点为O,则其电势为16V,故co为等势面,电场线与等势面垂直,则电场线沿着bo方向,故B错误;C、由上可知,电场线沿着bo方向,质子从b运动到c做为在平抛运动,垂直于bo方向做匀速运动,位移大小为x=2L •=L,则运动时间为t==.故C正确.D、依据W=qU,质子从b点运动到c点,电场力做功为W=qU bc=1e×(24V﹣16V)=8eV,故D错误;故选:C.点评:本题的关键在于找出等势面,然后才能确定电场线,要明确电场线与等势线的关系,能利用几何关系找出等势点,再依据等势线的特点确定等势面.2.如图所示,不计质量的光滑小滑轮用细绳悬挂于墙上O点,跨过滑轮的细绳连接物块A、B,A、B都处于静止状态,现将物块B向右移至C点后,A、B仍保持静止,下列说法中正确的是( )

)A.“轨道康复者”的加速度是地球同步卫星加速度的5倍B.“轨道康复者”的速度是地球同步卫星速度的倍C.站在赤道上的人观看到“轨道康复者”向西运动D.“轨道康复者”可在高轨道上加速,以实现对低轨道上卫星的挽救考点:人造卫星的加速度、周期和轨道的关系.分析:依据万有引力供应向心力,结合轨道半径的关系得出加速度和周期的关系.依据“轨道康复者”的角速度与地球自转角速度的关系推断赤道上人看到“轨道康复者”向哪个方向运动.解答:解:万有引力供应卫星做圆周运动的向心力;A、由牛顿其次定律得:G=ma,解得:a=,由于“轨道康复者”绕地球做匀速圆周运动时的轨道半径为地球同步卫星轨道半径的五分之一,则“轨道康复者”的加速度是地球同步卫星加速度的25倍,故A错误.B、由牛顿其次定律得:G =m,解得:v=,由于“轨道康复者”绕地球做匀速圆周运动时的轨道半径为地球同步卫星轨道半径的五分之一,则“轨道康复者”的速度是地球同步卫星速度的倍.故B正确.C、由于“轨道康复者”绕地球做匀速圆周运动的周期小于同步卫星的周期,则小于地球自转的周期,所以“轨道康复者”的角速度大于地球自转的角速度,站在赤道上的人用仪器观看到“轨道康复者”向东运动.故C错误.D、“轨道康复者”要在原轨道上减速,做近心运动,才能“挽救”更低轨道上的卫星.故D错误.故选:B.点评:解决本题的关键知道万有引力供应向心力这一重要理论,并能机敏运用,以及知道卫星变轨的原理,知道当万有引力大于向心力,做近心运动,当万有引力小于向心力,做离心运动.4.如图所示,绝缘弹簧的下端固定在光滑斜面底端,弹簧与斜面平行,带电小球Q(可视为质点)固定在绝缘斜面上的M点,且在通过弹簧中心的直线ab上.现将与Q大小相同,带电性也相同的小球P,从直线ab 上的N点由静止释放,若两小球可视为点电荷.在小球P与弹簧接触到速度变为零的过程中,下列说法中正确的是( )A.小球P的速度肯定先增大后减小B.小球P的机械能肯定在削减C.小球P速度最大时所受弹簧弹力和库仑力的合力为零D.小球P与弹簧系统的机械能可能增加考点:功能关系;机械能守恒定律;库仑定律.分析:本题中有库仑力做功,机械能不守恒;机械能守恒是普遍遵守的定律;小球的速度变化可从受力与能量两种观点加以分析.解答:解:A、小球先沿斜面加速向下运动,后减速向下运动,当弹簧压缩量最大时,小球静止,故A正确;B、依据除了重力和弹力之外的力做功量度机械能的变化,小球P除了重力和弹力之外的力做功还有弹簧的弹力和库仑斥力做功,开头弹簧的弹力和库仑斥力的合力方向可能向上,也就是可能做负功,所以小球P的机械能可能增大,故B 错误;C、小球P的速度肯定先增大后减小,当p的加速度为零时,速度最大,所以小球P速度最大时所受弹簧弹力、重力沿斜面对下的分力和库仑力的合力为零,故C错误;D、依据能量守恒定律知,小球P的动能、与地球间重力势能、与小球Q间电势能和弹簧弹性势能的总和不变,由于在小球P与弹簧接触到速度变为零的过程中,Q对P的库仑斥力做正功,电势能减小,所以小球P与弹簧系统的机械能肯定增加,故D错误.故选:A.点评:留意机械能守恒的条件是只有重力或弹力做功,从能量转化的角度讲,只发生气械能间的相互件转化,没有其他形式的能量参与.5.如图所示,质量相同且分布均匀的两个圆柱体a、b靠在一起,表面光滑,重力均为G,其中b的下一半刚好固定在水平面MN的下方,上边露出另一半,a静止在平面上,现过a的轴心施以水平作用力F,缓慢的将a拉离平面始终滑到b的顶端,对圆柱体a的移动过程分析,应有( )A.拉力F先增大后减小,最大值是GB.开头时拉力F 最大为G,以后渐渐减小为0C.a、b间压力由0渐渐增大,最大为GD.a、b 间的压力开头最大为G,而后渐渐减小到G考点:共点力平衡的条件及其应用;力的合成与分解的运用.专题:共点力作用下物体平衡专题.分析:a球缓慢上升,合力近似为零,分析a受力状况,由平衡条件得到F以及b球对a的支持力与θ的关系式,即可分析其变化.解答:解:对于a球:a球受到重力G、拉力F和b球的支持力N,由平衡条件得:F=NcosθNsinθ=G则得:F=GcotθN=依据数学学问可知,θ从30°增大到90°,F和N均渐渐减小,当θ=30°,F 有最大值为G,N有最大值为2G,故B正确,ACD错误.故选:B.点评:本题运用隔离法争辩,分析a球受力状况,得到两个力的表达式是解题的关键.6.如图所示,两平行金属板间有一匀强电场,板长为l,板间距离为d,在板右端l处有一竖直放置的光屏M.一带电荷量为q、质量为m的质点从两板中心射入板间,最终垂直打在M屏上,则下列结论正确的是( )A .板间电场强度大小为B .板间电场强度大小为C.质点在板间运动的时间跟它从板的右端运动到光屏的时间相等D.质点在板间运动的时间大于它从板的右端运动到光屏的时间考点:带电粒子在匀强电场中的运动.专题:带电粒子在电场中的运动专题.分析:依据题意分析,质点最终垂直打在M屏上,必需考虑质点的重力.质点在平行金属板间轨迹应向上偏转,飞出电场后,质点的轨迹向下偏转,质点才能最终垂直打在M屏上.第一次偏转质点做类平抛运动,其次次斜向上抛运动平抛运动的逆过程,运用运动的分解法,依据对称性,分析前后过程加速度的关系,再争辩电场强度的大小.水平方向质点始终做匀速直线运动,质点在板间运动的时间跟它从板的右端运动到光屏的时间相等.解答:解:A、B据题分析可知,质点在平行金属板间轨迹应向上偏转,做类平抛运动,飞出电场后,质点的轨迹向下偏转,质点才能最终垂直打在M屏上,前后过程质点的运动轨迹有对称性,如图,可见两次偏转的加速度大小相等,依据牛顿其次定律得,qE﹣mg=mg,得到E=.故A错误,B正确.C、D由于质点在水平方向始终做匀速直线运动,两段水平位移大小相等,则质点在板间运动的时间跟它从板的右端运动到光屏的时间相等.故C正确,D错误.故选BC点评:本题是类平抛运动与平抛运动的综合应用,基本方法相同:运动的合成与分解.7.如图所示,一足够长的光滑斜面,倾角为θ,一弹簧上端固定在斜面的顶端,下端与物体b相连,物体b 上表面粗糙,在其上面放一物体a,a、b间的动摩擦因数为μ(μ>tanθ),将物体a、b从O点由静止开头释放,释放时弹簧恰好处于自由伸长状态,当b滑到A点时,a刚好从b上开头滑动;滑到B点时a刚好从b 上滑下,b也恰好速度为零,设a、b间的最大静摩擦力等于滑动摩擦力.下列对物体a、b运动状况描述正确的是( )A.从O到A的过程,两者始终加速,加速度大小从mgsinθ始终减小,在A点减为零B.经过A点时,a、b均已进入到减速状态,此时加速度大小是g(μcosθ﹣sinθ)C.从A到B的过程中,a的加速度不变,b的加速度在增大,速度在减小D.经过B点,a掉下后,b开头反向运动但不会滑到开头下滑的O点考点:牛顿其次定律;物体的弹性和弹力.专题:牛顿运动定律综合专题.分析:μ>tanθ,则μmgcosθ>mgsinθ,当b滑到A点时,a刚好从b上开头滑动说明ab加速度开头不同.解答:解:A、释放时弹簧恰好处于自由伸长状态,斜面光滑,二者具有向下的加速度,弹簧伸长,弹簧拉力增大,则二者做加速度渐渐减小的加速运动,以a为争辩对象,取沿斜面对下为正方向,有:mgsinθ﹣f=ma得:f=mgsinθ﹣ma可见只要a物体具有向下的加速度,则f<mgsinθ<μmgcosθ,即所受摩擦力小于最大静摩擦力,物体不会滑动,当二者加速度为零,即(M+m)gsinθ=F,之后弹簧连续伸长,则ab开头具有沿斜面对上的加速度,即开头减速运动,以a为争辩对象,取沿斜面对上为正方向,有:f﹣mgsinθ=ma当f有最大值时a有最大值,又f max=μmgcosθ则a=μgcosθ﹣gsinθ,之后b加速度连续增大而a加速度保持不变,二者发生相对滑动,故经过A点时,a、b均已进入到减速状态,此时加速度大小是g(μcosθ﹣sinθ),A错误,BC正确;D、在a落下后,b将以新的平衡位置为中心做谐振动,由对称性可推断出b将冲过o点,即b的最高点将在o点之上选项D错误.故选:BC.点评:该题是牛顿其次定律的直接应用,本题ABC三个选项留意使用临界分析法即可得到正确结果,D选项关键点在于a脱离b后,b的受力满足机械能和简谐振动模型.二、解答题(共5小题,满分68分)8.为了“验证牛顿其次定律”,某同学设计了如下试验方案:A.试验装置如图甲所示,一端系在滑块上的轻质细绳通过转轴光滑的轻质滑轮,另一端挂一质量为m=0.5kg

65m/s2.③由A步骤可知,取下细绳和钩码后,滑块受到的合外力F=0.5×9.8=4.9N,依据牛顿其次定律得:M=kg;故答案为:①F;②1.65;③2.97点评:探究加速度与质量关系时,应把握拉力不变而转变小车质量,试验时要留意小车质量应远大于重物质量.纸带处理时能利用匀变速直线的规律以及推论解答试验问题,在平常练习中要加强基础学问的理解与应用,提高解决问题力量9.探究力对原来静止的物体做的功与物体获得的速度的关系,试验装置如图甲所示.试验过程中有平衡摩擦力的步骤,并且设法让橡皮筋对小车做的功以整数倍增大,即分别为W0、2W0、3W0、4W0…①试验中首先通过调整木板倾斜程度平衡摩擦力,目的是C (填写字母代号).A.为了释放小车后小车能做匀加速运动B.为了增大橡皮筋对小车的弹力C.为了使橡皮筋对小车做的功等于合外力对小车做的功D.为了使小车获得较大的动能②图乙是在正确操作状况下打出的一条纸带,从中截取了测量物体最大速度所用的一部分,已知相邻两点打点时间间隔为0.02s,则小车获得的最大速度v m=1.22m/s(保留3位有效数字).③几名同学在试验中分别得到了若干组橡皮筋对小车做的功W与小车获得最大速度v m的数据,并利用数据绘出了图丙给出的四个图象,你认为其中正确的是D.考点:探究功与速度变化的关系.专题:试验题;动能定理的应用专题.分析:该试验的目的以及试验数据处理的方法;该试验平衡摩擦力的缘由;该试验是如何确定外力做功以及如何通过纸带猎取小车运动的最终速度大小;如何通过图象来处理数据等.解答:解:①试验中通过调整木板倾斜程度平衡摩擦力,目的是为了使橡皮筋对小车所做功即为合外力对小车所做的功,故ABD错误,C正确.故选:C.②由所打的点可知,DG之间小车做匀速直线运动,速度最大,小车获得的最大速度为:v m=m/s=1.22m/s故答案为:1.22.③橡皮筋对小车做的功W与小车的动能关系知:W=,即有:•W,依据数学学问可知D正确.故选:D.故答案为:①C;②1.22;③D点评:本题考查了该试验的具体操作细节和数据的处理,对于这些基础学问肯定要通过亲自动手试验加深理解.10.如图所示,倾角为37°的足够长粗糙斜面下端与一足够长光滑水平面相接,斜面上有两小球A、B,距水平面高度分别为h1=5.4m和h2=0.6m.现由静止开头释放A球,经过一段时间t后,再由静止开头释放B球.A 和B与斜面之间的动摩擦因素均为μ=0.5,重力加速度g=10m/s2,不计空气阻力,设小球经过斜面和水平面交界处C机械能不损失,(sin37°=0.6,cos37°=0.8).求:(1)为了保证A、B两球不会在斜面上相碰,t最长不能超过多少?(2)若A球从斜面上h1高度处由静止开头下滑的同时,B球受到恒定外力作用从C点以加速度a 由静止开头向右运动,则a为多大时,A球有可能追上B球?考点:牛顿运动定律的综合应用;匀变速直线运动的位移与时间的关系;机械能守恒定律.专题:牛顿运动定律综合专题.分析:(1)由牛顿其次定律求出物体在斜面上的加速度,利用运动学公式求出在斜面上的时间,为了保证A、B两球不会在斜面上相碰,则满足:t=t1﹣t2;(2)若A球能追上B球,则二者位移应当相等,求出加速度解答:解:(1)球在斜面上时,由牛顿其次定律得:gsin37°﹣μmgcos37°=ma,解得,A、B 的加速度:,A球到C 点的时间为:,B球到C 点的时间为:,A、B两球不会在斜面上相碰,t最长为:t=t A﹣t B=2s;(2)A球到C点的速度为:v A=a A t A=6m/s,设t时刻A能追上B ,则:,又:,解得:a≤1m/s2,即B球加速度a 最大不能超过1m/s2;答:(1)为了保证A、B两球不会在斜面上相碰,t最长不能超过2s.(2)B球加速度a 最大不能超过1m/s2时,A球有可能追上B球.点评:本题考查追击问题,过程较简单,分析清楚物体运动过程是正确解题的前提与关键,利用牛顿其次定律、运动学公式即可正确解题.11.(17分)如图所示,在距水平地面高h1=1.2m的光滑水平台面上,一个质量m=1kg的小物块压缩弹簧后被锁扣K锁住,储存了肯定量的弹性势能E p.现打开锁扣K,物块与弹簧分别后将以肯定的水平速度v1向右滑离平台,并恰好从B点沿切线方向进入光滑竖直的圆弧轨道BC.已知B点距水平地面的高h2=0.6m,圆弧轨道BC的圆心O与水平台面等高,C点的切线水平,并与水平地面上长为L=2.8m的粗糙直轨道CD平滑连接,小物块沿轨道BCD运动并与右边的竖直墙壁会发生碰撞,重力加速度g=10m/s2,空气阻力忽视不计.试求:(1)小物块由A到B的运动时间.(2)压缩的弹簧在被锁扣K锁住时所储存的弹性势能E p.(3)若小物块与墙壁碰撞后速度反向、大小变为碰前的一半,且只会发生一次碰撞,那么小物块与轨道CD 之间的动摩擦因数μ应当满足怎样的条件.考点:功能关系;平抛运动.分析:首先要清楚物块的运动过程,A到B的过程为平抛运动,已知高度运用平抛运动的规律求出时间.知道运动过程中能量的转化,弹簧的弹性势能转化给物块的动能.从A点到最终停在轨道CD上的某点p,物块的动能和重力势能转化给摩擦力做功产生的内能.依据能量守恒列出能量等式解决问题.由于p点的位置不确定,要考虑物块可能的滑过的路程.解答:解;(1)小物块由A运动到B的过程中做平抛运动,在竖直方向上依据自由落体运动规律可知,小物块由A运动到B的时间为:t==s=s≈0.346s(2)依据图中几何关系可知:h2=h1(1﹣cos∠BOC),解得:∠BOC=60°依据平抛运动规律有:tan60°=,解得:v1===2m/s依据能的转化与守恒可知,原来压缩的弹簧储存的弹性势能为:E p =mv12==2J(3)依据题意知,①μ的最大值对应的是物块撞墙前瞬间的速度趋于零,依据能量关系有:mgh1+E p>μmgL代入数据解得:μ<②对于μ的最小值求解,首先应推断物块第一次碰墙后反弹,能否沿圆轨道滑离B点,设物块碰前在D处的速度为v2,由能量关系有:mgh1+E p=μmgL+mv22第一次碰墙后返回至C处的动能为:E kC =mv22﹣μmgL可知即使μ=0,有:mv22=14Jmv22=3.5J<mgh2=6J,小物块不行能返滑至B点.故μ的最小值对应着物块撞后回到圆轨道最高某处,又下滑经C恰好至D点停止,因此有:mv22≤2μmgL,联立解得:μ≥综上可知满足题目条件的动摩擦因数μ值:≤μ<答:(1)小物块由A到B的运动时间是0.346s.(2)压缩的弹簧在被锁扣K锁住时所储存的弹性势能E p是2J.(3)μ的取值范围:≤μ<.点评:做物理问题应当先清楚争辩对象的运动过程,依据运动性质利用物理规律解决问题.关于能量守恒的应用,要清楚物体运动过程中能量的转化.12.(19分)如图所示,一辆在水平地面上向右做直线运动的平板车,长度L=6m,质量M=10kg,其上表面水平光滑且距地面高为h=1.25m,A、B是其左右的两端点,在A端固定一个与车绝缘的、质量与大小忽视不计的带电体Q,其电量Q=﹣5×10﹣6C.在地面上方的空间存在着沿小车运动方向的、区域足够大的匀强电场(忽视Q的影响),场强大小E=1×107N/C.在t=0时刻,小车速度为v0=7.2m/s,此时将一个质量m=1kg的小球轻放在平板车上距离B 端处的P点(小球可视为质点,释放时对地的速度为零).经过一段时间,小球脱离平板车并落到地面.已知平板车受到地面的阻力与它对地面的压力成正比,且比例系数μ=0.2,其它阻力不计,重力加速度g=10m/s2.试求:(1)从t=0时起,平板车能连续向右运动的最大距离.(2)小球从t=0时起到离开平板车时所经受的时间.(3)从t=0时起到小球离开平板车落地时止,带电体Q的电势能的变化量.考点:匀强电场中电势差和电场强度的关系;自由落体运动;牛顿其次定律.专题:电场力与电势的性质专题.分析:(1)从t=0时起,平板车受到向左的电场力,向右做匀减速运动,由牛顿其次定律求得加速度的大小,由运动学速度位移关系公式求出向右运动的最大距离.(2)依据牛顿其次定律求出小车向右运动的加速度大小,依据运动学公式求出小车向右运动的位移和时间,推断小球是否会从小车的左端掉下,若未掉下,依据牛顿其次定律求出小车向左运动的加速度大小,小球从右端掉下,依据小球小车向左运动的位移求出向左运动的时间,两个时间之和即为小球从轻放到平板车开头至离开平板车所用的时间.(3)求出小车在小球做自由落体运动时间内的位移,结合小车向右运动的位移和向左运动的位移,求出小车的位移.再求出电场力做功,即可求得带电体Q的电势能的变化量.解答:解:(1)以平板车为争辩对象,依据受力分析和牛顿运动定律有:F=EQ=50N,方向向左.a1==7.2m/s2x1==3.6m (2)因x1<4m,故小球不会从车的左端掉下,小车向右运动的时间t1==1s小车向左运动的加速度a2==2.8m/s2小球掉下小车时,小车向左运动的距离x2=x1+=5.6m小车向左运动的时间t2==2s所以小球从轻放到平板车开头至离开平板车所用的时间t=t1+t2=3s(3)小球刚离开平板车时,小车向左的速度的大小为:v2=a2t2=5.6m/s小球离开平板车后,车的加速度大小a3==3m/s2小球离开车子做自由落体的运动h=gt32t3=0.5s车子在t3时间内向左运动的距离x3=v2t3+a3t32=3.175m车子在从t=0时起到小球离开平板车落地时止,向左运动的位移为ss=x3+x2﹣x1=5.175m故在从t=0时起到小球离开平板车落地时止,带电体Q的电势能的变化量为△E,△E=﹣Fs=﹣258.75J答:(1)从t=0时起,平板车能连续向右运动的最大距离为3.6m.(2)小球从t=0时起到离开平板车时所经受的时间为3s.(3)从t=0时起到小球离开平板车落地时止,带电体Q的电势能的变化量为﹣258.75J.点评:本题是一个多过程问题,关键是理清小车在整个过程中的运动状况,结合牛顿其次定律和运动学公式进行求解.。

1、阅读下面的文字,完成下面小题。
材料一:可移动文化遗产的保护是指运用各种方法延长可移动文化遗产寿命的专业性活动。
保护技术推进的核心是找到与遗产变化状况相适应的保护方法,以便及时对藏品进行预警、干预,使藏品保持健康的状态。
在此过程中,预防、治理、修复三个方面的技术运用起着至关重要的作用。
预防是所有的减缓文化遗产恶化和损毁的行为的总称,它涉及光照度、环境条件、安全、防火和突发事件的准备等方面。
治理是通过外接的干预直接作用于可移动文化遗产的保护行为,是为了消除正在损毁遗产的外界因素,从而使遗产恢复到健康的状态。
根据可移动文化遗产遭受“病痛”情形的差异,治理技术可以分为杀虫、去酸、脱水和清洁等类型。
修复是对已经发生变形或变性的遗产进行处理,使之恢复到原有的形态或性质。
修复的内容大致分为两个方面:一是清除文物和标本上的一切附着物;而是修补文物和标本的残缺部分。
(摘自周耀林《可移动文化遗产保护策略研究》)材料二:以温度45℃、相对湿度54%为标准寿命(设其指数为1.44),计算在温度15℃、35℃和湿度14%、34%、74%条件下,纸张的寿命和标准寿命的倍数关系,结果见下表:(摘编自李景仁等《图书档案保护技术手册》)材料三:毛里求斯是非洲一个岛国,位于赤道南部的西印度洋上,气候湿热多雨。
