1．(17)(1)用万用表的欧姆挡测电阻时，下列说法中正确的是(　　 )(填字母代号)

　　 A．万用电表的指针达满偏时，被测电阻值最大

　　 B．万用电表的指针指示零时，说明通过被测电阻的电流最大

　　 C．测电阻前，把面板上的选择开关置于相关的欧姆挡上，将两表笔的金属杆直接短接，调整欧姆挡的调零旋钮使指针指在电流的最大刻度处

　　 D．用欧姆表的R×10Ω挡时,指针指在刻度20-40的正中央,则被测电阻的阻值为300Ω

　　 E．测量前，待测电阻应跟别的元件和电源断开

　　 F．用欧姆表的R×100Ω挡测电阻时，若指针指在零处附近，则应换用R×1kΩ挡

　 (2)用伏安法测电阻时有如图所示的甲、乙两种接法，下面说法中正确的是(　 　)

A．当R_x＜＜R_A时，用甲种接法误差较小，当R_x＞＞R_A时，用乙种接法误差较小

B．当R_x＞＞R_A时，用甲种接法误差较小，当R_x＜＜R_A时，用乙种接法误差较小

C．当R_x＜＜R_A时，用甲种接法误差较小，当R_x＞＞R_v时，用乙种接法误差较小

D．当R_x＞＞R_v时，用甲种接法误差较小，当R_x＜＜R_A时，用乙种接法误差较小

删除：把多余的词用斜线(/)划掉。

修改：在错的词下划一横线，并在该词下面写出修改后的词。

注意：1. 每处错误及其修改均仅限一词；

2. 只允许修改10处，多者(从第11处起)不记分。

　 A　 painter hang his or her finished picture on a wall, and everyone can see it. A

composer writes work, but no one can hear it until it is performing. Professional singers

and players　 have greater responsibilities, for the composer is utterly independent on them.

A student of music needs as long and as hardly a training to become a performer as a medical

student needs to become a doctor. Most training is concerning with technique, for musicians

have to have the muscular proficiency of an athlete or a ballet dancer. Singers practice to

breathing every day, as his　 voices would be not beautiful with controlled muscular support.

String(弦乐) players practice moving the finger of the left hand up and down, while drawing

the bow to and fro with the right hand---two entirely different movements.
