15．B
解析：B
【解析】
【分析】
【详解】

解析：C
【解析】
【分析】
【详解】
考查倒装和条件状语从句。句意：——我很想和你一起踢球，但我有重要的事要去做。——如果你不去，那我也不去。分析句子可知，句意上明显是顺承前句的“你不……”表示“我也不……”，此时要用neither或nor引导的部分倒装结构。而答语的句子使用了条件状语从句，要符合“主将从现”的现象，即在空白处的主句中要使用一般将来时，使用助动词will。综上正确的答案应该是“neither/nor will I”。故选C项。
18．D
解析：D
【解析】
【分析】
考查结果状语和时间状语从句。
【详解】
考查结果状语和时间状语从句。句意：“当汤姆听说他的朋友背叛他时，他是如此的生气，以至于他立刻将来信撕成了两半。”此句应分为两部分来看.第一部分是so...that...句型,他生气的结果是撕了信，所以that应该在后半部分。再分析前半部分，可知此处是when
引导的时间状语从句，表示当他得知他的朋友背叛他时，所以A正确。
【点睛】
此题的解题关键是分清楚两个从句与主句的关系。根据句意，可知结果状语为后半句撕了信这件事，所以此处是so…that句型，再根据句意，判断前半分句是时间状语，所以用when。
19．D
解析：D
【解析】
【分析】
【详解】
考查时间状语从句。句意：一看见他，我就知道他是那个警察正在寻找的人。分析句子，I saw him 与I knew he was the man..为两个完整的句子，此处需用连词连接。The instant 译为“一……就”时，引导时间状语从句符合句意。故选D项。

精选受力分析练习题15道（含答案及详解） 1．如右图1所示，物体M 在竖直向上的拉力F 作用下静止在斜面上，关于M 受力的个数，下列说法中正确的是（D ） A ．M 一定是受两个力作用 B ．M 一定是受四个力作用 C ．M 可能受三个力作用 D ．M 不是受两个力作用就是受四个力作用 2、如图2所示,物体A 靠在竖直墙面上,在力F 作用下,A 、B 保持静止.物体B 的受力个数为 ( ) A.2 B.3 C.4 D.5 答案 C 解析 B 物体受四个力的作用,即重力、推力F 、物体A 对B 的支持力和物体A 对B 的摩擦力. 3、如图3所示，物体A 、B 、C 叠放在水平桌面上，水平力F 作用于C 物体，使A 、 B 、 C 以共同速度向右匀速运动，那么关于物体受几个力的说法正确的是 （ A ） A ．A 受6个， B 受2个， C 受4个 B ．A 受5个，B 受3个，C 受3个 C ．A 受5个，B 受2个，C 受4个 D ．A 受6个，B 受3个，C 受4个 4、如图4所示，在水平力F 作用下，A 、B 保持静止.若A 与B 的接触面是水平的，且F≠0.则关于B 的受力个数可能为( ) A.3个 B.4个 C.5个 D.6个 解析：对于B 物体，一定受到的力有重力、斜面支持力、A 的压力和A 对B 的摩擦力，若以整体 为研究对象，当F 较大或较小时，斜面对B 有摩擦力，当F 大小适当时，斜面对B 的摩擦力为零，故B 可能受4个力，也可能受5个力.答案：BC 5、如右图5所示，斜面小车M 静止在光滑水平面上，一边紧贴墙壁．若再在斜面上加一物体m ，且M 、m 相对静止，小车后来受力个数为( B ) A ．3 B ．4 C ．5 D ．6 解析： 对M 和m 整体，它们必受到重力和地面支持力．对小车因小车静止，由平衡条件知墙面对小车必无作用力，以小车为研究对象．如右图所示，它受四个力；重力M g ，地面的支持力F N1，m 对它的压力F N2和静摩擦力Ff ，由于m 静止，可知F f 和F N2的合力必竖直向下，故B 项正确． 6、如图6所示，固定斜面上有一光滑小球，有一竖直轻弹簧P 与一平行斜面的轻弹簧Q 连接着， 小球处于静止状态，则关于小球所受力的个数不可能的是 （ A ） A ．1 B ．2 C ．3 D ．4 7、如图7所示，在竖直向上的恒力F 作用下，物体A 、B 一起向上做匀加速运动。在运动过程 中，物体A 保持和墙面接触，物体B 紧贴在A 的下表面，A 和B 相对静止，则下列说法正确的是（ CD ） A.竖直墙面对物体A 有摩擦力的作用 B.如果物体运动的加速度较小，则物体A 、B 间可以没有摩擦力作用 图 1 图 2 图 3 图 4 图 5 图 6 图7
