高考英语状语从句专项训练
专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。

高考物理真题分类汇编(详解)
高中物理学习材料 （马鸣风萧萧**整理制作） 2011年高考物理真题分类汇编（详解） 功和能 1．（2011年高考·江苏理综卷）如图所示，演员正在进行杂技表演。由图可估算出他将一只鸡蛋抛出的过程中对鸡蛋所做的功最接近于 A ．0.3J B ．3J C ．30J D ．300J 1.A 解析：生活经验告诉我们：10个鸡蛋大约1斤即0.5kg ，则一个鸡蛋的质量约为 0.5 0.0510 m kg = =，鸡蛋大约能抛高度h =0.6m ，则做功约为W=mgh =0.05×10×0.6J=0.3J ，A 正确。 2．（2011年高考·海南理综卷）一物体自t =0时开始做直线运动，其速度图线如图所示。下列选项正确的是（ ） A ．在0～6s 内，物体离出发点最远为30m B ．在0～6s 内，物体经过的路程为40m C ．在0～4s 内，物体的平均速率为7.5m/s D ．在5～6s 内，物体所受的合外力做负功 v/m ·s -1 10
2.BC 解析：在0~5s,物体向正向运动，5~6s向负向运动，故5s末离出发点最远，A错；由面积法求出0~5s的位移s1＝35m, 5~6s的位移s2＝－5m,总路程为：40m，B对；由面积法求出0~4s的位移s=30m，平度速度为：v＝s/t＝7.5m/s C对；由图像知5～6s过程物体加速，合力和位移同向，合力做正功，D错 3．（2011年高考·四川理综卷）如图是“神舟”系列航天飞船返回舱返回地面的示意图，假定其过程可简化为：打开降落伞一段时间后，整个装置匀速下降，为确保安全着陆，需点燃返回舱的缓冲火箭，在火箭喷气过程中返回舱做减速直线运动，则 A．火箭开始喷气瞬间伞绳对返回舱的拉力变小B．返回舱在喷气过程中减速的主要原因是空气阻力 C．返回舱在喷气过程中所受合外力可能做正功D．返回舱在喷气过程中处于失重状态 3.A 解析：在火箭喷气过程中返回舱做减速直线运动，加速度方向向上，返回舱处于超重状态，动能减小，返回舱所受合外力做负功，返回舱在喷气过程中减速的主要原因是缓冲火箭向下喷气而获得向上的反冲力。火箭开始喷气前匀速下降拉力等于重力减去返回舱受到的空气阻力，火箭开始喷气瞬间反冲力直接对返回舱作用因而伞绳对返回舱的拉力变小。 4．（2011年高考·全国卷新课标版）一质点开始时做匀速直线运动，从某时刻起受到一恒力作用。此后，该质点的动能可能 A．一直增大 B．先逐渐减小至零，再逐渐增大 C．先逐渐增大至某一最大值，再逐渐减小 D．先逐渐减小至某一非零的最小值，再逐渐增大 4.ABD 解析：当恒力方向与速度在一条直线上，质点的动能可能一直增大，也可能先逐渐减小至零，再逐渐增大。当恒力方向与速度不在一条直线上，质点的动能可能一直增大，也可能先逐渐减小至某一非零的最小值，再逐渐增大。所以正确答案是ABD。
