根据“用电流表、电压表测电阻”的实验，完成下列要求．

（1）在图1所示的电路中，有一根导线尚未连接，请用笔画线代替导线在图中正确连接．（用2B铅笔在答题纸的相应位置连接）

（2）实验所用滑动变阻器标有“10Ω  1A”字样，电源电压不变，所有元件均完好．移动变阻器滑片至中点时（即变阻器连入电路的电阻为5欧），电流表的示数为0.3安，电压表的示数如图2所示，则待测电阻两端的电压为______伏，待测电阻的阻值为______欧，电源电压为______伏．

（3）继续实验，测出电阻值分别为10.1欧和10.2欧，可求得电阻的平均值为______欧．（计算电阻时，精确到0.1欧）

Most of the inhabitants live in mud-brick homes, their (1)  walls insulating against the afternoon heat. Flat roofs, exposed (2)  the northern evening breezes, serve as cool sleeping (3)  as well as storage areas. Villagers plaster the outer walls (4)  often trim them in blue, a color they believe (5)  off the evil eye.

All (17)  said, government sponsored building programs have also brought newer (18)  residences and utilities to some villages, particularly those outside (19)  Nile Valley in the Oases and the Red Sea (20)  areas.
