A. Lack of stone images also reflects religious belief.

B. Art is a good means to know about people’s faith.

C. Artists express their feelings and opinions in their works.

D. People know more about our culture through learning art history.

E. Art is by all means relevant to history.

F. Art history provides information of different places and people.

小题1:____________________________

A study of art history might be a good way to learn more about a culture than it is possible to learn in general history classes. Most typical history courses concentrate on politics, economics and war. But art history focuses on much more than this because art reflects not only the political values of a people, but also religious beliefs, emotions, and psychology.

小题2:____________________________

In addition, information about the daily activities of our ancestors---or of people very different from our own---can be provided by art. In short, art expresses the essential qualities of a time and a place, and a study of it clearly offers us a deeper understanding than what can be found in most history books.

小题3:____________________________

In history books, objective information about the political life of a country is presented; that is, facts about politics are given, but opinions are not expressed. Art, on the other hand, is subjective: it reflects subjective emotions and opinions. The great Spanish painter Francisco Goya was perhaps the first truly “political” artist. In his well-known painting The Third of May 1808, he criticized the Spanish government for its misuse of power over people. Over a hundred years later, symbolic images were used in Pablo Picasso’s Guernica to express the horror of war. Meanwhile, on another continent, the powerful paintings of Diego Rivera, Jose Clemente Orozco, and David Alfaro Siqueiros---as well as the works of Alfredo Ramos Martins---depicted（描述）these Mexican artists’ deep anger and sadness about social problems.

小题4:____________________________

In the same way, art can reflect a culture’s religious beliefs. For hundreds of years in Europe, religious art was almost the only type of art that existed. Churches and other religious buildings were filled with paintings that depicted people and stories from the Bible. Although most people couldn’t read, they could still understand biblical（圣经的）stories in the pictures on church walls.

小题5:____________________________

By contrast, one of the main characteristics of art in the Middle East was (and still is) its absence of human and animal images. This shows the Islamic belief that statues are unholy. Something else can be more religiously symbolic in history.

如图所示电路，电源两端电压保持不变，滑动变阻器的最大电阻值为R₁，R₂为定值电阻，灯泡L标有“12V 9W”字样，且不计灯丝电阻随温度的变化。当开关都闭合时，灯泡L恰能正常发光，将开关 S₁、S₃断开，S₂闭合后，改变滑动变阻器的滑片P的位置，使滑动变阻器连人电路的电阻分别为0.25R₁和R₁，这两种情况下，滑动变阻器消耗的电功率相等。当开关S₁、S₂断开，S₃闭合，滑片P在变阻器的左端时，灯泡L的实际电功率为额定电功率的1/16。求：

（1）灯泡正常发光时电流表的示数I_A；

（2）滑动变阻器的最大电阻值R₁；

（3）灯泡正常发光时电阻R₂消耗的电功率P₂。
