江苏省扬州中学教育集团树人学校高二上学期开学测试英语----精校解析Word版
【解析】
【详解】考查lie和lay的用法。句意:那个躺在地上的男孩对他的父亲撒谎说那只母鸡那天下了两个蛋。第一个空,lie(平放,躺卧),这里是现在分词做后置定语,答案为lying;第二空,lie(说谎),过去式是lied,lie to sb.向某人说谎,答案为lied;第三空,lay(下蛋,安置),其过去式、过去分词是laid,根据that day可知用一般过去时态,故选B。
A. while B. that
C. as D. when
【答案】D
【解析】
考查定语从句。句意:在半夜时分丈夫把我叫醒看足球赛。the middle of night是先行词,在从句中做时间状语,故用关系副词when=at which。综上,选D。
点睛:此题考生极易选B,以为强调句型it is…that….,但要强调the middle of night,前面应该加介词at,变成It was at the middle of nightthatmy husband woke me up and told me to watch the football game.再去掉itis…that…,还原为陈述句式:my husband woke me up and told me to watch the football game at the middle of night.没有at,句子不成立。
3._____in the queue for half an hour, Tom suddenly realized that he had left his wallet at home.
A. To wait B. Have waited
C. Having waited D. To have waited

参考答案:B2. (多选题)如图所示,A、B两物体的质量m A>m B,中间用一段细绳相连并有一被压缩的弹簧,放在平板小车C上后,A、B、C均处于静止状态.若地面光滑,则在细绳被剪断后,A、B从C上未滑离之前,A、B沿相反方向滑动过程中()A.若A、B与C之间的摩擦力大小相同,则A、B组成的系统动量守恒,A、B、C组成的系统动量也守恒B.若A、B与C之间的摩擦力大小不相同,则A、B组成的系统动量不守恒,A、B、C 组成的系统动量也不守恒C.若A、B与C之间的摩擦力大小不相同,则A、B组成的系统动量不守恒,但A、B、C组成的系统动量守恒D.以上说法均不对参考答案:AC【考点】动量守恒定律.【分析】系统动量守恒的条件是合外力为零,通过分析研究对象的受力情况,确定合外力,即可进行分析和判断.【解答】解:A、若A、B与C之间的摩擦力大小相同,在细绳被剪断后,弹簧释放的过程中,A、B所受的滑动摩擦力方向相反,则对于A、B组成的系统所受的合外力为零,动量守恒;对三个物体组成的系统,竖直方向上重力与支持力平衡,水平方向不受外力,合外力为零,所以A、B、C组成的系统动量也守恒,故A正确.B、C、若A、B与C之间的摩擦力大小不相同,在细绳被剪断后,弹簧释放的过程中,A、B所受的滑动摩擦力方向相反,则对于A、B组成的系统所受的合外力不为零,动量不守恒;但对三个物体组成的系统,合外力为零,A、B、C组成的系统动量仍守恒,故B 错误,C正确.D、由上分析可知D错误.故选:AC3. 汽车以 72 km / h 的速度通过凸形桥最高点时,对桥面的压力是车重的 3 / 4 ,则当车对桥面最高点的压力恰好为零时,车速为A . 40 km / hB 40 m / sC 120 km / hD . 120 m / s参考答案:B4. 位于同一高度的两个相同小球A、B,A球自由释放,B球以速度v0平抛,不计空气阻力,下列说法正确的是()A.A、B两球落地时动量相同B.A、B两球落地时动能相同C.A球运动过程中,相等时间内动量改变量相同D.A球运动过程中,相等时间内动能变化相同参考答案:C【考点】动量定理;平抛运动;动能定理.【分析】根据动能定理比较落地的动能大小,结合动量的表达式比较落地的动量.根据动量定理比较动量的变化量.【解答】解:AC、两球落地时的速度方向不同,则其动量不同,根据动量定理,自由落体运动的时间和平抛运动的时间相等,则有:mgt=△p,可知相同时间内动量的该变量相同,故A错误,C正确.B、由动能定理:mgh=,因h一样,而v0不同,则其落地动能不同,故B 错误D、由动能定理:mgh=,在相同时间内因h不一样,则其动能的改变量不相同,故D错误故选:C5. 下列电器中,应用了电磁感应原理的是A.蓄电池B.发电机C.电熨斗D.电磁铁参考答案:B二、填空题:本题共8小题,每小题2分,共计16分6.
