条件句从句主句 真实一般现在时一般将来时 情态动词+动原祈使句 非真实 一般过去时 be动词用（were） would/could+动原初中英语――条件状语从句（讲解&练习） Ⅰ条件状语从句的定义 Ⅱ条件状语从句的引导词 1.if引导的条件状语从句：表示在某种条件下某事很可能发生。 If we pay much attention to the earth, we'll have a better world. 如果我们多关爱地球，就会拥有一个更美好的世界 If it rains tomorrow, what shall we do? 如果明天下雨，我们怎么办？ 注意：if还可以引导虚拟条件句，表示不可实现的条件，从句中多用一般过去时或过去完成时。 What would happen if there were no water ? 如果没有水会怎样？ 2.unless引导的条件状语从句，unless的意思是如果不，除非。可与if...not互换。 You will fail in English unless you work hard. 你英语考试会不及格的，除非你更加努力。 3.as /so long as引导的条件状语从句：as /so long as意思是“只要” So long as you're happy,i will be happy. 只要你高兴，我就高兴。 Ⅲ条件状语从句的种类 Ⅳ条件状语从句的时态原则 用法例句 ①主句为一般将来时态，if从句用一般 现在时态（即主将从现）。We will stay at home if it rains tomorrow. 如果明天下雨，我将要呆在家。 ②主句中含有情态动词，if从句用一 般现在时态。If you finish your homework, you can go home now.如果你做完了作业，你现在可以回家了。 ③主句为祈使句，if从句用一般现在 时态。Don’t jump into the river if you feel very hot. 如果你感到很热，不要跳入河里。 ④主句为过去将来时，if从句用一般 过去时态（如果涉及到be动词， 一律都用were）。此时，表达的是和现实相反的推测，用虚拟语 气。If I were you, I wouldn’t do it like that.如果我是你，我就不会那么做的。 If you gave me some money, I would be very happy. 如果你给我一些钱，我就会很高兴的。 二、if 引导的条件状语从句 （1）“if 从句+祈使句”的句子。其实，if 作为一个连词，主句也可以是其他形式的句子。 例如：If you want to go, please let me know. (2)“祈使句 + and (or)+ 陈述句”

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
