D．An Unfortunate ExperienceBCHICAGO—Monkeys perform mental maths; pigeons can select the picture that doesn't belong．Humans may not be the only animals that plan for the future, say researchers reporting on the latest studies of animal mental ability．Edward Wassennan, a professor of experimental psychology at the University of Chicago, says that, like people, pigeons and baboons（狒狒）were able to tell which picturesshowed similar items, like triangles or dots, and which showed different items．In the last 20 years there has been a major revolution in the understanding of animals, added Nicola S．Clayton, a professor of comparative cognition （认知）at the University of Cambridge England．"Animals not only use tools．There is also evidence that some of them save tools for future use," she says．"Planning ahead was once thought to be unique to humans．We now know that's not true．"For example, she said, crows have been seen stashing（把……藏起来）food away for the next day, and even finding ways to protect it from being stolen．Clayton and Elizabeth Branhon have studied how human adults and babies, lemurs（狐猴）and monkeys think about number without using language．After seeing the same number of different objects, infants notice when the number changes．So do macaques．Indeed, college students and macaques seem equally able to estimate numbers of objects without actually counting them．That ability can be useful to macaques in determining whether there is enough food in an area, or to get a sense of how large their group is compared to competing groups．The researchers are currently working to see if monkeys can recognize the concept of zero．The new studies finding increasing similarities between animals and human mental abilities may be making some people uneasy, Wassennan says．With the aim of learning how much the ability to think is general throughout the animal kingdom, he says, "the evidence that we collect constantly surprises us．"41．Which of the following would be the best title for the text?A．How Animals Plan for Their FutureB．The Newest Discovery About Animals and HumansC．The Ability to Plan for the FutureD．Researchers Say Animals Plan for the Future42．The aim of the studies was to discover____．A．whether animals like monkeys can recognize the concept of zeroB．how much thinking ability is common among animalsC．what kinds of animals can perform mental mathsD．why animals save tools for future use43．In the past scientists thought that ___．A．besides humans, only baboons had the ability to plan for the futureB．animals had limited ability to plan for the futureC．besides humans, only monkeys and pigeons could plan for the futureD．only humans could make plans for the future44．The underlined word "macaques" in Paragraph 5 refers to __ _．A．human adults B．human babiesC．college students D．monkeys45．According to the text, _ __．A．Wasserman has been studying animals for over 20 yearsB．most people now take it for granted that animals plan for the futureC．there are some similarities between animals and human mental abilitiesD．current evidence shows that almost all animals can plan for the futureCThe Adventure Guides ProgramNew Member

travelersC．international studentsD．children with bad memoriesDThe English language, like football and other sports, began in England and has spread to every comer of the globe．Today more than a billion people-speak English．It is becoming the world's language: the language of the Internet, of business, of international flight —the pathway of global communication and global access to knowledge．And it has become the vehicle for hundreds of millions of people of all countries to connect with each other, in countless ways．Indeed, English is much more than a language: it is a bridge across borders and cultures, a source of unity in a rapidly changing world．English does not make us all the same —nor should it, for we honor who we distinctly are．But it makes it possible for us to speak to each other, to better understand each other．So it is a powerful force not just for economics, business and trade, but for mutual respect and progress．For Britain, this is not a matter of narrow national pride．It is an accident of history ?a wave of knowledge and commerce, which gathered even greater global force in the post-war era, that-gave the world the English language．English is our heritage, but it is also becoming the common future of human commerce and communication．This is a great opportunity for Britain—and a measure of the greatness that lies not in empire's territory but through a language that has the power to bring this world of over 200 countries and billions of people closer together, with the versatility（多才多艺）to evolve and adapt．We will take up with vigor （魅力）the bold （冒险的）task of making our language the world's common language of choice．The language that helps the world talk, laugh and communicate together．But there are millions of people in every continent who are still denied this chance to learn English—prevented from enjoying many of the benefits of the Internet, commerce and culture．But no one —however poor, however distant ?should be denied the opportunity that the English language provides．51．In the opinion of the writer, English plays a role of_ __．A．making all the people around the world the sameB．making all the people move across borders freelyC．uniting the world people into a countryD．promoting mutual understanding and respect52．Which word can express the writer's opinion on how English has become a language of the world?A．Natural B．Accidental C．Gradual D．Inevitable53．How should the British treat the power of English?A．They should make full use of it．B．They should be proud of it.C．They should take it for granted.D．They should share it with other people.54．The writer seems to think that English provides the British with a chance _ __．A．to restore the empire of Britain in its historyB．to occupy as much territory as possible in every continentC．to make the world people choose to learn EnglishD．to bring 200 hundred countries under the control of Britain 55．If the writer continues to write this passage, what will he discuss?A．How to do business with the distant people．B．How to make the poor people get rid of poverty．C．How to help the distant people have access to the Internet．D．How to provide the poor people with the chance to learn English．第Ⅱ卷（非选择题共35分）第三部分：写作（共两节，满分35分）第一节：阅读表达（共5小题；每小题2分，满分10分）Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it．They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer．Anger is a normal emotion that we all feel from time, to time．Some people express anger openly in a calm reasonable way．Others burst with anger, and scream and yell．Yet a few people keep their anger inside．They can not or will hot express it．This is called repressing anger．For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it．They said that when a person is angry, the brain releases the same hormones （荷尔蒙）．They speed the heart rate, raise blood pressure, or sugar into the blood, etc．In general, the person feels excited and ready to act．Some doctors say that both repressing and expressing anger can be dangerous．They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure．Docors say the solution is learning how to deal with anger．They say the first step is to admit that you are angry and to recognize the real cause of the anger, men decide if the cause is serious enough to get angry about．If it is, they say, "Do not express your anger while angry．Wait until your anger has cooled down and you are able to express yourself calmly and reasonably．"Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry．They said that laughter is much healthier than anger．56．What's the author's purpose by writing this passage? （No more than 15 words）57．What's the meaning of the underlined word "repressing" in Paragraph 2? （No more than 5 words）58．According to the passage, what are the two common ways for people to express their anger? （No more than 20 words）59．Why do doctors warn us not to get angry easily? （No more than 15 words）60．How can you deal with anger successfully in your daily life? （No more than 20 words）61．下面4幅图片描述的是星期天上午在中山公园里发生的一件事。

内环式梯田是把支离破碎的土地封闭成一个个凹地，降雨时雨水汇集到梯田底部形成一个个微型湖泊，泥沙也随雨水淤积于其底部，从而减小了泥沙的入河量，久而久之黄土高原也将趋于平缓。

8 次α衰变和 6次β衰变，每经过一次β衰变就会有一个中子转变为质子，同时放出一个电子，所以共有6个中子转化为质子，C正确．D、X射线能够穿透物质，可以来检查物体内部情况，所以机场的安检设备，它能轻而易举地窥见箱内的物品，这种设备工作时利用的电磁波是X射线，D错误；故选：C点评：本题考查了原子核式结构模型，原子跃迁，衰变的实质，和X射线的应用．2．如图所示，甲、丙物体在水平外力F的作用下静止在乙物体上，乙物体静止在水平面上．现增大水平外力F，三物体仍然静止，则下列说法正确的是（）A．乙对甲的支持力可能增大 B．乙对甲的摩擦力一定增大C．乙对地面的压力一定不变 D．甲对丙的摩擦力可能增大考点：共点力平衡的条件及其应用；物体的弹性和弹力．专题：共点力作用下物体平衡专题．分析：正确的受力分析是解决问题的关键，三物体仍然静止，说明物体处于平衡状态，所受外力合力为0，以甲乙丙整体为研究对象，当F增大时，地面对整体的摩擦力亦增大，但支持力不变．再分别以甲、丙为研究对象即可求解．解答：解：如图，对甲进行受力分析有：F合x=Fcosθ+f﹣Gsinθ=0…1）F合y=FN﹣Gcosθ﹣Fsinθ=0 (2)AB、由（1）知f=Gsinθ﹣Fcosθ，由于未知摩擦力的方向，故当f为正值时，F增大则f 减小，若f为负值即沿斜面向下时，当F增大则f亦增大；由（2）知，FN=Gcosθ+Fsinθ，当F增大时，则支持力一定增大，不是可能增大，故A错误，B错误；C、把甲乙丙看成一个整体，受重力、支持力、摩擦力和推力，根据平衡条件，支持力等于整体的重力，不变；再根据牛顿第三定律，压力与支持力相等，也不变，故C正确；D、对丙进行受力分析，丙处于静止状态，水平方向不受摩擦力，故D错误．故选：C．点评：考虑到物体的受力分析，物体始终处于静止状态，即满足合外力为零，另物体受到斜面的摩擦力，因不知倾角和动摩擦因数的大小，摩擦力可能沿斜面向上也可能沿斜面向下，所以当F增大时，摩擦力可以变大也可以变小，要根据具体题目加以讨论．3．利用霍尔效应制作的霍尔元件，广泛应用于测量和自动控制等领域．如图是霍尔元件的工作原理示意图，磁感应强度B垂直于霍尔元件的工作面向下，通入图示方向的电流I，C、D两侧面会形成电势差UCD，下列说法中正确的是（）A．电势差UCD仅与材料有关B．仅增大磁感应强度时，C、D两面的电势差变大C．若霍尔元件中定向移动的是自由电子，则电势差UCD＞0D．在测定地球赤道上方的地磁场强弱时，元件的工作面应保持水平方向考点：霍尔效应及其应用．分析：在霍尔元件中，移动的是自由电子，根据左手定则判断出电子所受洛伦兹力方向，从而知道两侧面所带电荷的电性，即可知道C、D两侧面会形成电势差UCD的正负．CD间存在电势差，之间就存在电场，电子在电场力和洛伦兹力作用下处于平衡，根据平衡推导出电势差UCD与什么因素有关．解答：解：A、根据左手定则，电子向C侧面偏转，C表面带负电，D表面带正电，所以D 表面的电势高，则UCD＜0．CD间存在电势差，之间就存在电场，电子在电场力和洛伦兹力作用下处于平衡，设霍尔元件的长宽高分别为a、b、c，有q=qvB，I=nqvS=nqvbc，则U=．故A、C错误，B正确．D、在测定地球两极上方地磁场强弱时，应将元件的工作面保持水平，让磁场垂直通过．故D正确．故选：BD．点评：解决本题的关键知道霍尔元件中移动的是自由电子，以及自由电子在电场力和洛伦兹力作用下处于平衡．4．如图所示，楔形木块abc固定在水平面上，粗糙斜面ab和光滑斜面bc与水平面的夹角相同，顶角b处安装一定滑轮．质量分别为M、m（M＞m）的滑块，通过不可伸长的轻绳跨过定滑轮连接，轻绳与斜面平行．两滑块由静止释放后，沿斜面做匀加速运动．若不计滑轮的质量和摩擦，在两滑块沿斜面运动的过程中（）A．两滑块组成系统的机械能守恒B．重力对M做的功等于M动能的增加C．轻绳对m做的功等于m动能的增加D．两滑块组成系统的机械能损失等于M克服摩擦力做的功考点：功能关系．分析：机械能守恒的条件是只有重力或系统内弹簧的弹力做功．功与能量的转化紧密联系，功是能量转化的量度，其中重力做功与重力势能变化、除了重力以外的力做功与机械能的变化有关．解答：解：A、由于斜面ab粗糙，滑块M运动过程中，摩擦力做负功，故两滑块组成系统的机械能不守恒，故A错误．B、重力对M做的功等于M重力势能的变化，合力对M做功才等于M动能的增加，故B错误．C、m受到绳子的拉力向上运动，拉力做正功，故m的机械能一定增加，而且轻绳对m做的功等于m机械能的增加，故C错误；D、根据功能原理得知：除重力弹力以外的力做功，将导致机械能变化，摩擦力做负功，造成机械能损失，则有：两滑块组成系统的机械能损失等于M克服摩擦力做的功．故D正确．故选：D．点评：本题关键理解掌握机械能守恒的条件和功能关系，重力做功对应重力势能变化、弹力做功对应弹性势能变化、合力做功对应动能变化、除重力或系统内的弹力做功对应机械能变化．5．如图所示，矩形线圈abcd在匀强磁场中可以分别绕垂直于磁场方向的轴P1和P2以相同的角速度匀速转动，当线圈平面转到与磁场方向平行时（）A．线圈绕P1转动时的电流等于绕P2转动时的电流B．线圈绕P1转动时的电动势小于绕P2转动时的电动势C．线圈绕P1和P2转动时电流的方向相同，都是a→b→c→dD．线圈绕P1转动时dc边受到的安培力大于绕P2转动时dc边受到的安培力考点：交流发电机及其产生正弦式电流的原理；安培力；导体切割磁感线时的感应电动势．分析：相同的线框在匀强磁场中以不同的转轴转动会产生交流电，由于它们的角速度相同，线框面积相同，则它们的产生的最大值相同，所以它们的有效值也相同．再由安培力公式借助于电流来比较大小．解答：解：A、由于它们的角速度相同，线框面积相同，则它们的产生的最大值相同，所以它们的有效值也相同，因此线圈绕P1转动时的电流等于绕P2转动时的电流，故A正确；B、由于它们的角速度相同，线框面积相同，则它们的产生的最大值相同，所以它们的有效值也相同，因此线圈绕P1转动时的电动势等于绕P2转动时的电动势，故B错误；C、相同的线框在匀强磁场中以不同的转轴转动会产生交流电，所以它们的方向变化的，故C错误；D、由于它们的角速度相同，线框面积相同，则它们的产生的最大值相同，所以它们的有效值也相同，因此线圈绕P1转动时的电流等于绕P2转动时的电流，而安培力F=BIL，则有线圈绕P1转动时dc边受到的安培力等于绕P2转动时dc边受到的，故D错误；故选：A点评：相同的线框虽然转轴不同，但它们的最大值、有效值、平均值及周期、频率、角速度均相同，因此线框的转动与转轴无关．二、多项选择题（每小题有多个正确选项，每小题6分，共18分）6．图甲为一列简谐横波在t=0.10s时刻的波形图，P是平衡位置为x=1.0m处的质点，Q是平衡位置为x=4.0m处的质点，图乙为质点Q的振动图象，则（）A．

t（cm）C．从t=0.10s到t=0.25s，质点P通过的路程为30cmD．从t=0.10s到t=0.25s，该波沿x轴负方向传播了6m考点：波长、频率和波速的关系．专题：振动图像与波动图像专题．分析：根据甲乙两图可以求出该波的波长和周期，从而求出波速，t=0.10s时Q点在平衡位置上，由乙图知下一时刻向下振动，从而确定了该波向左传播．解答：解：A、由乙图中Q点的振动图象可知t=0.15s时Q点在负的最大位移处，故具有正向最大加速度，故A正确；B、根据公式x=Asin，质点Q简谐运动的表达式为（cm），故B错误；C、质点在一个周期内通过个路程为4个振幅长度，故t=0.10s到t=0.25s的四分之三周期内，但P点的起始位置不在平衡位置，也不在最大位移处，故质点P通过的路程不为3倍振幅，即不是30cm，故C错误．D、根据甲乙两图可知波长和周期，则波速：v===40m/s，故从t=0.10s到t=0.25s，波沿x负方向传播了6m，故D正确；故选：AD．点评：本题有一定的综合性，考察了波动和振动图象问题，关键是会根据振动情况来判定波的传播方向．7．以不同的抛射角抛出三个小球A、B、C，三球在空中的运动轨迹如图所示，下列说法中正确的是（）A． A、B、C三球在运动过程中，加速度都相同B． B球的射程最远，所以最迟落地C． A球的射高最大，所以最迟落地D．
