三、阅读理解（2 *10 = 20’）
A
Do you hope to do a lot of homework every evening? Are you interested in your English classes? Who do you want to teach you? Maybe you have lots of questions in your mind before school starts.
Well, I want to give you some good advice on these problems.
First, keep calm(平静). Don’t worry about all the problems yo u have. Put your heart into learning, and you can find something you are interested in. Do it actively.
Second, try your best to finish your homework quickly. Don’t spend a lot of time on it. Do more reading or writing in English. Think about the problems you have and solve them at once. Don’t stay up(熬夜) late, or you can’t study well the next day.
Third, invent something instead of copying or repeating. If you can remember the words in your way, you can tell your teachers you don’t like the way of copying them again and again. Be sure, you must pass the test. I think your teachers will agree with you. And they can give you some interesting work to do.
School is really a good place for us to learn. Believe in your teachers and yourself. You are the best one and you can do everything well.

B
If you go into the forest with your friends, stay with them. If you don’t, you may get lost（迷路）. If you get lost, this is what you should do. Sit down and stay where you are. Don’t try to find your friends---let them find you. You can help them find you by staying in one place. There is another way to help your friends or other people to find
you. You can shout or whistle（吹口哨）three times. Stop. Then shout or whistle three times again. Any signal（信号）given three times is a call for help.
Keep shouting or whistling. Always three times together. When people hear you, they will know that you are not just making a noise for fun. They will let you know that they have heard our signal. They will give you two shouts or two whistles. When a signal is given twice, it is an answer to a call for help.
If you don’t think that you will get help before night comes, try to make a little house with branches（树枝）. Make yourself a bed with leaves and grass.
When you need some water, you have to leave your little house to look for it. Don’t just walk away. Pick off small branches and drop（丢）them when you walk to go back again easily. When you are lost, the most important thing to do is to stay in one place.

A. try to find your friends

图3 线圈中心轴做匀速圆周运动，所以产生的电流为交流电． 答案：AC 3．如图3所示，线圈M和线圈P绕在同一铁芯上．设两个线圈中的电流方向与图中所标的电流方向相同时为正．当M中通入下列哪种电流时，在线圈P中能产生正方向的恒定感应电流() 解析：据楞次定律，P中产生正方向的恒定感应电流说明M中通入的电流是均匀变化的，且方向为正方向时应均匀减弱，故D正确． 答案：D 图4 4．(2008年重庆卷)如图4所示，粗糙水平桌面上有一质量为m的铜质矩形线圈，当一竖直放置的条形磁铁从线圈中线AB正上方等高快速经过时，若线圈始终不动，则关于线圈受到的支持力N及在水平方向运动趋势的正确判断是() A．N先小于mg后大于mg，运动趋势向左 B．N先大于mg后小于mg，运动趋势向左 C．N先小于mg后大于mg，运动趋势向右 D．N先大于mg后小于mg，运动趋势向右 解析：由题意可判断出在条形磁铁等高快速经过线圈时，穿过线圈的磁通量是先增加后减小，根据楞次定律可判断：在线圈中磁通量增大的过程中，线圈受指向右下方的安培力，在线圈中磁通量减小的过程中，线圈受指向右上方的安培力，故线圈受到的支持力先大于mg 后小于mg，而运动趋势总向右，D正确． 答案：D 5．如图5(a)所示，圆形线圈P静止在水平桌面上，其正上方悬挂一相同线圈Q，P和Q 共轴，Q中通有变化电流，电流随时间变化的规律如图(b)所示，P所受的重力为G，桌面对P的支持力为F N，则() 图5 A．t1时刻F N＞G B．t2时刻F N>G C．t3时刻F N 饶平二中高二物理(选修3-2)电磁感应单元测试题 班级 姓名 座号 评分 一、选择题: 1、 在图1中，相互靠近的两个圆形导线环，在同一平面内，外面一个与电池、滑动变阻器串接，里面一个为闭合电路。当变阻器的电阻变小时，在里面的导线环上各段所受的磁场力的方向是：( ) A 、向着圆心。 B 、背离圆心。 C 、垂直纸面向外。 D 、没有磁场力作用。 2、如图2所示电路，在L 1线圈中感应电流从左向右通过电流表的条件是：( ) A 、K 断开瞬间。 B 、K 接通后，变阻器向右滑动。 C 、K 接通后， 将软铁心插入线圈L 2中。 D 、上述方法都不行。 3、一圆形线圈，一半置于匀强磁场中，磁场方向垂直纸面向里，如图3所示。为使线圈中感应电流为顺时针方向，应使线圈：( ) A 、沿+x 方向平动 B 、沿x 轴转动90° C 、沿+y 方向平动 D 、绕y 轴转动90° 4、如图4所示，电键K 原来是接通的，这时安培表中指示某一读数，在 把K 断开瞬间，安培表中出现：( ) A 、电流强度立即为零。 B 、与原来方向相同逐渐减弱的电流。 C 、与原来方向相同突然增大的电流。 D 、与原来方向相反突然增大的电流。 二、填空题： 5、半径为a 的半圆弧形硬质导线P Q 以速度v 在水平放置的平行导轨上运动。匀强磁场的磁感应强度为B ，方向与导轨平面垂直并指向纸里(如图5)。R 是固定电阻。设导轨、导线和P Q 的电阻以及P Q 与导轨的摩擦均可忽略，当导线P Q 作匀速运动时，外力的功率是 G K L L 1 2 x y o A K R R L 1 2 R a v P 图 1 图 3 图 4 图 5 图 2 7B Unit2单元综合测试卷(A) 一、单词辨音(5%) ( )1.A. plate B. flat C. manager D. lamp ( )2.A. sound B. country C. double D. enough ( )3.A. farm B. artist C. large D. warm ( )4.A. city B. capital C. notice D. mile ( )5.A. over B. college C. most D. notice ( )6.A. lucky B. full C. study D. hundred ( )7.A. notice B. collect C. cook D. cool ( )8.A. station B. manager C. palace D. lamp ( )9.A. football B. neighbourhood C. cook D. pool ( )10.A.afraid B. train C. says D. waiter 二、根据汉语注释和对话提示，写出单词的正确形式(10%) 1.
