甲和△F 乙的关系，然后利用p=分析△p 甲和△p 乙，即可．【解答】解：（1）当将物块放在甲液体中，由于物块密度大于液体甲的密度，所以物块将沉底，F 浮＜G，因为液体甲对容器底部的压力增加量△F 甲=F 浮，圆柱体乙对水平地面压力增加量△F 乙=G，所以F 甲＜△F 乙；（2）由图可知，S 甲＞S 乙，则由p=可得，△p 甲＜△p 乙，故选A．二、填空题（共23分）请将结果填入答题纸的相应位置．9．远距离输电时为了减少输电线上的电能损失，常采用高压输电（选填“高压”或“低压”）．在家庭电路中，消耗的电能常用电能表来测量．标有“220V100W”的电视机正常工作1小时耗电0.1度．【考点】JN：电能的输送；J6：电功的测量；J8：电功率与电能、时间的关系．【分析】①远距离输电，当功率一定时，提高电压，从而使电线中的电流减小，则电线上损失的电能减小；②用来测量用户消耗的电能仪表是电能表；③已知电视机的电功率和工作时间，根据公式W=Pt可求电视机消耗的电能．【解答】解：①当输出功率一定时，若提高电压，则由P=IU可知，电流降低，从而使电线上电阻的损失的功率减小，进而减小电能的损失；②电能表是用来测量用户消耗电能的；③由P=可得，电视机正常工作1小时消耗电能：W=Pt=0.1kW×1h=0.1kW•h=0.1度．故答案为：高压；电能；0.1．10．篮球是中考体育测试的项目之一，如图所示，篮球被投出后球在上升过程中动能变小，惯性不变（均选填“变大”、“变小”或“不变”）．碰到篮板后篮球会弹回说明力可以改变物体运动状态．【考点】FL：动能大小的比较；6F：力的作用效果；6L：惯性．【分析】（1）物体的动能与物体质量和速度有关，在质量一定的情况下，速度越小，物体动能越小；（2）物体的惯性只与质量有关；（3）力的作用效果有两个：一是改变物体的形状，二是改变物体的运动状态．【解答】解：篮球被投出后在上升过程中，篮球的质量不变，速度减小，篮球的动能减少，其高度增加，重力势能增大；在此过程中篮球的质量不变，故惯性不变；碰到篮板后被弹回，是因为篮板作用在篮球上的力改变篮球的运动状态．故答案为：变小；不变；运动状态．11．如图所示，分别用力F 1和F 2匀速提起同一重物C，则F 1大于F 2（选填“大于”、“等于”或“小于”）；若C重2牛，被匀速提升0.5米，则拉力F 1做功1焦，此过程中，C

求出拉力做的功；（3）物体具有的机械能是动能与势能的总和．【解答】解：左图是定滑轮，右图是动滑轮，当滑轮间摩擦不计，物重大于滑轮重时，使用右图中的滑轮可以省力，使用左图中的滑轮不省力，故F1大于F2；若C 重2牛，被匀速提升0.5米，则拉力F 1做功W 1=F 1s=2N×0.5m=1J；在匀速上升过程中物体C 的质量不变，高度升高，所以动能不变，重力势能增大，故机械能增大．故答案为：大于；1；变大．12．如图所示，将重力为20牛的物体浸没在水中，物体排开水的体积为2×10﹣3米3，则物体受到的浮力为19.6牛；它所受重力和浮力的合力大小为0.4牛；增大物体在水中的深度，它受到的浮力将不变（选填“变大”、“不变”或“变小”）．【考点】8O：阿基米德原理．【分析】（1）知道物体的体积（排开水的体积），由阿基米德原理及浮力公式F 浮=ρ水gV 排可以求出物体受到的浮力；浮力减去重力等于物体所受合力．（2）当物体所处的深度增加时，物体排开水的体积不变，由阿基米德原理可知浮力变化情况．【解答】解：（1）当物体浸没水中时，物体排开水的体积等于物体的体积，物体受到的浮力：F 浮=ρ水gV 排=ρ水gV 物体=1.0×103kg/m 3×9.8N/kg×2×10﹣3m 3=19.6N；合力为F 合=F 浮﹣G=20N﹣19.6N=0.4N．（2）当物体所处的深度增加时，V 排不变，由F 浮=ρ水gV 排，可知，物体受到的浮力不变．故答案为：19.6；0.4；不变．13．某导体两端的电压为3伏时，10秒内通过导体横截面的电荷量为3库，通过该导体的电流为0.3安，这段时间内电流做功为9焦，该导体两端电压改变为6伏时，其电阻为10欧．【考点】H4：电量及其计算；IH：欧姆定律的应用．【分析】已知10秒内通过某导体横截面的电荷量，根据I=求出通过的电流，根据欧姆定律求出导体的电阻，再根据W=UIt=UQ 求出电流做的功．【解答】解：通过该导体的电流：I===0.3A；由I=可得，导体的电阻：R===10Ω；电流做的功：W=UIt=UQ=3V×3C=9J；因为导体的电阻与材料、长度以及横截面积有关，与导体两端电压以及通过的电流无关，因此当导体两端电压改变为6伏时，其电阻仍为10Ω．故答案为：0.3；9；10．14．如图所示的电路，闭合电键，两灯均发光．①若在电路中添加一根导线，连接在a、b、c、d 四点中的两点．为避免实验中电源短路，导线不能连接ac两点．②若过了一会儿，两灯都熄灭了．已知电路中只有一处故障，且发生在L 1或L 2．（a）经过思考，小华认为故障一定不是短路．（选填“一定”、“可能”或“一定不”）（b）在电路中添加一只完好的小灯L 3，连接在a、b、c、d 四点中的两点．当小灯L 3连接的是bc 或dc两点时，闭合电键S，观察到小灯L 3始终不发光，就能判断故障一定发生在L 1上．【考点】HS：电路的基本连接方式；IE：电流表、电压表在判断电路故障中的应用．【分析】首先要明确电路的连接特点，再根据a、b、c、d 各点连接时对电路连接造成的影响，来确定电路的新变化，最终做出判断．灯泡不亮，可能是由于灯泡短路或断路或电路中除灯泡外存在断路造成的；【解答】解：①电源短路是指不经过用电器，用导线直接将电源的两极进行连接的电路，因此，读图可知，为避免实验中电源短路，导线不能连接ac 两点．②（a）L 1和L 2串联，闭合开关，电路正常工作，L 1和L 2都发光，说明电路正常；经过一段时间，两灯都熄灭，若电路中只有一处故障，且只发生在灯L 1和L 2上，则灯L 1断路或L 2断路，一定不是短路．（b）在电路中添加一只完好的小灯L 3，连接在a、b、c、d 四点中的两点．当小灯L 3连接的是bc 或dc 两点时，闭合电键S，观察到小灯L 3始终不发光，就能判断故障一定发生在L 1上．故答案为：①ac；②（a）一定不；（b）bc 或dc．15．某小组同学在学习完“大气压强”之后，通过上网查阅资料知道：在海拨2千米以内，每上升10米大气压强约减小100帕．还查阅到科学家在研究水的沸点和海拔高度之间关系时的相关数据，如表所示：海拔高度h/km 01369…水的沸点t/℃10097918070…根据对资料中信息的分析，回答以下问题：①在海拔8848米的珠穆朗玛峰顶上，水的沸点大约是71℃．水的沸点和大气压之间的大气压强越小，水的沸点越低关系；②若某校操场处的大气压强为p 0帕，该校实验楼的高度为H 米，则该实验楼楼顶的大气压强为p=p 0﹣×100Pa帕．【考点】8G：大气压强与高度的关系；1J：沸点及沸点与气压的关系．【分析】（1）根据表格中的数据进行分析；（2）根据表格中的数据得到高度与气压的关系．【解答】解：（1）由表格中的信息可知，当海拔为9000m 时，沸点为70℃，在海拔8848米的珠穆朗玛峰顶上，水的沸点大约是71℃，气压越大，沸点越高；（2）在海拨2千米以内，每上升10米大气压强约减小100帕，则楼顶的大气压强为：p=p 0﹣×100Pa=p 0﹣10H．故答案为：（1）71；大气压强越小，水的沸点越低；（2）p=p 0﹣×100Pa．三、作图题（共7分）请将图直接画在答题纸的相应位置，作图题必须使用2B 铅笔．16．在图中，重为4牛的均匀球体保持静止，用力的图示法画出该球所受的重力G．【考点】7B：重力示意图．【分析】先选出标度，然后根据重力的方向总是竖直向下，过重心表示出重力的大小及方向．【解答】解：选一段线段表示力的大小为2N，然后过球心作竖直向下的、大小为4N 的重力．如图所示：17．在图中，根据给出的入射光线AO 画出反射光线OB，并标出反射角的度数．【考点】A8：作光的反射光路图．【分析】根据反射定律：反射光线、入射光线和法线在同一平面内，反射光线、入射光线分居法线两侧，反射角等于入射角，作出反射光线并标出反射角及其度数．【解答】解：由入射角为60°，可得反射角也为60°，在法线右侧画出反射光线，反射角等于入射角为60°，如图所示：18．根据图中通电螺线管的N 极，标出磁感线方向、小磁针的N 极，并在括号内标出电源的正、负极．【考点】CV：通电螺线管的极性和电流方向的判断；C4：磁极间的相互作用；C7：磁感线及其特点；CB：安培定则．【分析】利用螺线管的右端为N 极，结合磁感线的特点和磁极间作用规律可以确定磁感线的方向和小磁针的N、S 极．利用线圈的绕向和螺线管的N、S 极，结合安培定则可以确定螺线管中电流的方向，进一步可以得到电源的正负极．【解答】解：螺线管的右端为N 极，磁感线从磁体的N 极出发，回到S 极，所以可以确定螺线管周围磁场的方向是从右向左的．当小磁针静止时，根据磁极间作用规律可知，靠近电磁铁N 极的一定是小磁针的S 极，由此可知小磁针的右下端为N 极．根据螺线管的右端为N 极，以及线圈的绕向利用安培定则可以确定螺线管中电流是从螺线管的左端流入右端流出．根据电流方向与电源正负极之间的关系：在电源外部电流从正极流出，回到负极，可以确定电源的正负极：左端为正极，右端为负极．如下图所示：四、计算题（共26分）请将计算过程和答案写入答题纸的相应位置．19．质量为1千克的铝块温度升高了20℃，求铝块吸收的热量Q 吸．[c 铝=0.9×103焦/（千克•℃）]．【考点】GG：热量的计算．【分析】知道铝块的质量、铝的比热容、铝块的温度升高值，利用吸热公式Q 吸=cm△t 求铝块吸收的热量．【解答】解：铝块吸收的热量：Q 吸=c 铝m△t=0.9×103J/（kg•℃）×1kg×20℃=1.8×104J．。

push the "close" button？You hope by pushing it，the elevator door will close faster．But what if the button is actually fake（假的）？Karen Penafiel is the executive director（执行董事）of the US National Elevator Industry．She said that elevators' "close" buttons are a complete trick，at least in the US，and that doors will not close any faster no matter how hard you push．In the 1990s the Americans with Disabilities Act（《美国残疾人法案》）was passed in the US．It means all elevators have to stay open long enough to allow disabled（残疾的）people to enter．Only US firefighters and elevator workers can really use the buttons with special keys．But the buttons aren't completely useless．According to psychologists（心理学家），fake buttons can make you feel better．They give you a sense of control that can help reduce stress．That's why some other buttons in our lives are fake，too．For example，many offices in the US have fake thermostats（温控器）．People may feel better when they think they can control the temperature in their workspace．You were told that traffic light buttons could help make the traffic signals change faster．But they may not really work either．However，even when people know these little "white lies"，they still push fake buttons．As long as the doors finally close，it seems worthy．John Kounios is a psychology professor at Drexel University in the US．He told The New YorkTimes that he always pushes the traffic light buttons．"After all，I've got nothing else to do while waiting．So why not push the button on the off chance that this one will work？"69．You push the "close" button in the US，the elevator door will．A．close immediatelyB．not be completely openC．play a trick on youD．not close as fast as you wish70．The US，in order for disabled people to go in safely，．A．elevator workers will press the "open" button for themB．they will be given a special key to use in the elevatorsC．all elevators are designed to open long enoughD．no "close" button is fixed on the elevators71．Which of the following is NOT mentioned as fake？A．Thermostat buttons．B．Elevator buttons．C．Traffic light buttons．D．Power buttons．72．There are quite a few fake buttons in our lives because they can．A．control people's sensesB．help people feel betterC．control the temperatureD．tell "white lies"73．The underlined words " on the off chance" in the last paragraph most probably mean ""．A．with the little hopeB．without any planC．with a great opportunityD．without any possibility74．The best title for the passage is．A．Button pushing societyB．Useless buttonsC．Buttons for disabled peopleD．Fake elevator buttons75．（12分）Choose the best words and complete the passage（选择最恰当的单词完成短文）Is it stressful and boring working at Google，one of the largest technology companies in the world？Not at all! （75），Google has the best working environment among the big companies in the United States．The working environment is quite（76）at Google．The company encourages staff to do whatever they want in the office．They can design their own desks or work stations．They can write down their ideas on the wall．When they are tired，they can take a nap（打盹）on the sofa．Animal lovers can（77）bring their pets to work．Google is home to every employee．In addition to offices，there are game rooms，hair salons，restaurants and gyms．After work，employees can have a swim in the swimming pool or enjoy a massage（按摩）．The company also encourages them to learn new things．It （78） a number of interesting free courses such as sign language，cooking，drawing and playing the piano．There is an interesting rule at Google﹣no staff member should be （100）feet away from food．Coffee bars and open kitchens are （79）．All food is free．There are thousands of different dishes in the main restaurant．One of its managers says，"We care for our employees'（80），so we encourage them to have healthy food．Our research shows that if people are provided with enough food，they make better choices．"To work hard and work well，you need to love what you are working on and whereyou are working．Google believes that an interesting and pleasant space helps people think more creatively．So it is trying hard to keep its title as the happiest workplace in the word．75．A．After all B．By the way C．For example D．In fact 76．A．surprising B．relaxing C．interesting D．amusing 77．A．almost B．ever C．even D．both 78．A．guides B．offers C．takes D．learns 79．A．everywhere B．somewhere C．anywhere D．nowhere 80．A．choice B．cooking C．health D．behavior 81．（14分）Read the passage and fill in the blanks with proper words（在短文的空格内填入适当的词，使其内容通顺．每空格限填一词，首字母已给）I remember a psychiatrist（精神病医生）once said that if you ever feel sad，the best thing to do is do something for someone else because it gets you focused．It's hard to be unhappy while serving someone else．A byproduct（副产品）of h（81）others is feeling wonderful yourself．I remember sitting in an airport one day，waiting for my flight．I was e（82）because I had been upgraded（升级）to a first﹣class ticket．I had the best seat on the plane，seat 1A．B （83）boarding，I noticed a young lady who had several carry﹣on bags and was holdng a crying baby．Having just finished reading a book on doing acts of kindness，I heard my conscience（良心）speak to me，"You guy，let her h（84）your ticket．" I fought these words for a while but finally gave in．"Excuse me，but it seems that you could use this first﹣class ticket more than me．I know how hard it can be flying with a k（85）．Why don't we trade（交换）our tickets．""Are you sure？""Oh yeah．I really don't mind．I'm just going to be working the whole time，anyway．""Well，thank you．That's very kind of you，" she said as we e（86）our tickets．As we boarded the plane，I was surprised at how good it made me feel to watch her sit down in seat 1A．In fact，at that time，seat 24B or wherever I was sitting didn't seem that bad at all．During the flight I was so curious to see how she was doing that I could h（87）stand（忍受）it．So I got up out of my seat，walked to the first﹣class section．There she was with her baby，both in big and comfortable seat 1A．And I felt like getting a million dollars．I've got to keep doing this kind of thing．88．（12分）Answer the questions（根据短文内容回答下列问题）Two close friends were Willie Brown and his little dog Bounce．Willie could never think of taking a walk without Bounce．Cake and play were equally shared between them．Willie taught his dog many tricks，and often said that Bounce could do almost anyhing in the world but talk．There came a time，however，when Bounce really told Willie's father something，though he could not talk．It was a bright summer afternoon．Willie had walked with Bounce down to the river，which was not more than two blocks from his father's store．Willie began to throw stones into the water，and Bounce lay on the grass，watching the flies（苍蝇）and catching any that came too near．There were some logs（圆木）in the river near the bank．Willie jumped upon one of them，to see if he could throw a stone across the river．Just as it left his hand，the log turned，and he fell into the water．He did not know how to swim，and there was no one to hear，though he called as loud as he could for help．Poor little Bounce gave a great barking of worry．He ran up and down the bank two or three times，barking，looking first at Willie and then around．Then he started to run as fast as he could，up the street to the store．When he got there the door was shut，but he scratched（挠）against it and barked loudly，until someone came and opened it．He caught hold of Mr．Brown's clothes then ran to the door，then back again，catching at him，barking，and jumping．Now，Mr．Brown thought，"Something must be wrong．" Immediately he followed Bounce to the riverside．Willie was saved in time．88．Bounce was Willie's close friend，wasn't he？89．How far was the river away from Wilie's father's store？90．Why did Willie jump on one of the logs in the river？91．How did Bounce feel when he found Willie in the river？92．Who do you think saved Willie's life？93．How do you like Bounce？Why？七、Writing（作文）（共20分）94．（20分）Write at least 60words on the topic "Something I want to do for my family"．（以"我想为家人做件事"为题写一篇不少于60词的短文，标点符号不占格．）The following questions are only for reference：1．What do you want to do for your family？2．Why do you want to do it？3．How do you plan to do it？2017年上海市松江区中考英语二模试卷参考答案与试题解析二、Choose the best answer（选择最恰当的答案）（每小题1分，共20分）1．（1分）Which of the following underlined parts is different in pronunciation from the others？（）A．You just leave the door open．B．He passed the driving test out of luck．C．Don't push me with your hand．D．It is not allowed to hunt for wild animals．【解答】just，luck和hunt三个单词中字母u的发音都是/ʌ/，push中字母u的发音是/ʊ/．故选：C．2．（1分）All of us opened our mouths in ________ surprise at the unexpected news．（）A．a B．an C．the D．/【解答】a

workspace．You were told that traffic light buttons could help make the traffic signals change faster．But they may not really work either．However，even when people know these little "white lies"，they
