Almost all of these caves have paintings on their ceilings or walls and they date from the 4th to 14th centuries. Wang Jinyu is an expert on these cave paintings (also called frescoes) and he says: We discovered frescoes containing scientific and technological content in almost all of the caves which have frescoes. What is remarkable about these cave paintings according to the Xinhua News Agency is that they provide evidence of scientific and technological inventions by ancient Chinese in maths, physics, chemistry, astronomy, geography, agronomy, architecture, textiles, traffic and transportation, arms and military equipment and medical sciences. If we want to find out what kind of technology people used in the past, we normally have to rely on archaeologists to find ruined buildings and parts of tools or instruments or machines. Archaeologists then try to reconstruct, sometimes with the help of puter technology, what these ancient buildings and objects must have looked like, and how they might have been made. Sometimes historians are lucky and find an ancient document with a written description of these ancient buildings and objects. 根據(jù)最后一段中的“The bicycle shop would provide the livelihood（生計）that would allow them to carry out their experiments on airplanes”自行車店將提供生計 ，允許他們在飛機上進行實驗 ，可知選D。 故選B。 （3）考查細節(jié)理解。根據(jù)第二段中的“They were just crazy about these things for the reasons that they did not yet understand”他們只是因為他們還不明白的原因 而對這些事情瘋狂 ；和第三段中的“Both boys loved to solve problems that seemed difficult to others.
