二、多项选择题（本题共4小题，每小题4分，共16分。在下列各题的四个选项中，有两个或两个以上选项符合题目要求，选对但不全者得2分，错选或不选得0分)9.两个力F,和F2之间的夹角为0，其合力为F。以下说法正确的是A.合力F总是大于力F,和F2中的任意一个B.若力F,和F2大小不变，角越小，则合力F就越大C.合力F的大小不会超过F与F2的大小之和D.若夹角不变，力F1大小不变，F2增大，则合力F一定增大10.如图所示，A、B、C三个物体，B、C用细绳相连，A放在B上，B放在水桌面上，各接触面间的动摩擦因数均为4，A、B、C的重力分别是GAG、GCA随B一起向右做匀速直线运动，则此过程中A.物体B与桌面间有摩擦力，大小为GC纸B.物体B与桌面间有摩擦力，大小为μGBC.物体B与物体A之间有摩擦力，大小为4GAD.物体B与物体A之间没有摩擦力11.A、B两物体的质量分别为m、ma,用原长为l、劲度系数为k的轻弹簧相连接，物体B放在水面上，A、B都处于静止状态。现对A施加一个竖直向上的力F,缓慢将A提起，直到使B恰好离开地面，重力加速度为g。则A.开始时弹簧的长度为mkB.开始时弹簧的长度为，-m8kC.这一过程中物体A上移的距离为m8kBB7777771772 77177771222D.这一过程中物体A上移的距离为m迢+m812.如图所示，质量为2kg的物块，恰好能沿倾角为α=37°的木板匀速下滑。现将该木板水固定在地面上，物块在与水面夹角为β=45°斜向下的推力作用下，恰好能沿水方向匀速运动，重力加速度g取10m/s2,sin37°=0.6，cos37°-0.8。则A.物块与木板间的动摩擦因数为0.75B.物块与木板间的动摩擦因数为0.25C.推力F大小为60W2ND.推力F大小为152N高一物理试卷第3页（共6页）

豫南九校2022一2023学年上期第二次联芳高三政治参考答案1.A【解析】如果消费者不购买商品，就不可能获得相应的赠品和奖品，消费者购买商品的钱，已经包括了买赠品或奖品的钱，因此，这些赠品或奖品是商品，是使用价值与价值的统一体，商家应该保证其具有合格的质量，①②正确，③错误；商家也从销售商品中获利了，应该对赠品或奖品的质量负责，④错误。2.D【解析】人民币汇率相对其他货币保持稳定，使用跨境人民币结算就能有效规避汇率风险，这是人民币跨境结算受欢迎的原因之一，②正确；我国外贸和对外投资出现较大增长，跨境结算的规模就会随之扩大，选择人民币跨境结算的也会随之增加，④正确；用人民币兑换外币的成本持续降低，就会刺激更多的企业和个人选择兑换外币，用外币的可能增加，①不符合题意；③不符合市场经济的要求，也不符合我国的实际政策，是错误的。3.C【解析】“北溪1号北溪2号”受损，会减少欧洲市场上的天然气供给，可能加剧供不应求，天然气期货涨价体现了供需变化影响价格，①正确；断气恐慌会进一步加剧人们的涨价预期，选择储存天然气的人会更多，④正确；一般情况下，涨价会导致该商品的需求减少，不是增加，②错误；价格是由生产该商品的社会必要劳动时间决定的，受供需影响，供应方也不能决定价格，③错误。4.D【解析】月饼包装“瘦身”，能够节约资源，选择这样的产品符合绿色消费的要求，③正确；一次吃完刚刚好的“点心化”月饼，能够减少浪费，有利于推动形成勤俭节约的良好风气，④正确；“瘦身”月饼的价格肯定会降一些，消费总需求不一定会增长，①不符合题意：购买这样的月饼，体现了人们的求实心理，不是求异心理，②不符合题意。5.B【解析】提高央企控股上市公司质量，能够从总体上提升国企的市场竞争力（②），进而更充分更高质量地发挥国有经济的控制力（①），利用高质量的国企带动经济发展质量的整体提升（④），B推理正确；公有制是我国国民经济的主体，③错误，含③的AC应该排除；巩固国有经济的支配地位，是完善我国所有制结构的具体举措，D项颠倒了⑤与⑥，通过完善我国的所有制结构，有利于推动经济高质量发展，D项也颠倒了⑥与④，应该排除。6.A【解析】经济发展是稳定和扩大就业的重要前提，经济高质量发展，有利于促进劳动者更充分更高质量的就业，①正确；国家实行就业优先战略，有利于推动就业，②正确：政府提供公益性岗位，不是解决就业的主要措施，③不是主要原因；④讲的是就业的影响，不是影响就业的原因，不符合题意。7.D【解析】购买农业保险，因旱情减产的农户，能够得到保险赔偿，减少损失，③正确；购买农业保险，受害农户能够得到保险赔偿，尽快地恢复生产，有利于稳定农业生产，保障国家的粮食安全，④正确；农业保险的保险对象不是农民的基本生活，①错误；自然灾害对农业生产的影响，不会因为购买了农业保险就减小了，②错误。8.A【解析】产业发展是增加收入的基础，实施乡村振兴、实现农业现代化，能够提高农业生产的效益，增加农民收入，缩小城乡收入差距，①正确；完善转移支付政策，加大对农村教育的投资，有利于提高农民及其子女的素质，素质高低直接影响到个人的收入，③高三政治参考答案第1页（共6页）
