托福阅读材料：Chemical Oracle

　　阿波罗是古希腊神话中的太阳神，他在希腊特尔斐的神庙是许多游客必去的著名景点之一。接下来的新托福考试阅读练习资料我们就要说说有关这个神庙的传说。

　　If you’re planning a trip to Greece in the future, you’ll want to schedule a visit to the temple of Apollo at Delphi. This famous temple was the home to the Pythia, a specially chosen and trained woman who, according to legend, channeled the voice and wisdom of Apollo, the god of prophecy. Generals, politicians, and private citizens of the ancient world flocked to Delphi to question the Pythia and seek her divinely inspired advice.

　　Ancient scientists and philosophers attributed the oracle’s power to vapors that bubbled up through a chasm and spring running through the oracle’s chamber inside the temple. Inhaling these vapors, according to the ancients, induced a trance-like state that endowed the oracles with divine prophetic power. Around 1900, excavations at Delphi revealed no chasm or escaping gases, and so the ancient accounts were discredited.

　　Until recently, that is Geological surveys of the area have detected two faults, or cracks in the earth’s crust, intersecting directly under the oracle’s chamber. Samples from Delphic spring water and rock from the intersecting faults revealed traces of several chemicals including ethylene. Tests have shown that when administered in proper dosage, ethylene can result in a trance state. Those affected are conscious, able to sit upright, can answer questions, and afterwards experience amnesia. Some subjects react violently, screaming and throwing themselves about.

　　Such reactions to ethylene are consistent with ancient reports. Unlike their Greek predecessors, modern scientists leave Apollo out of the picture. But once again, science gives at least partial credence to something that was once considered only a myth.
