reading passage.
题目原文：
In 1938 an archaeologist in Iraq acquired a set of clay jars that had been excavated two years earlier by villagers constructing a railroad line. The vessel was about 2,200 years old. Each clay jay contained a copper cylinder surrounding an iron rod. The archaeologist proposed that vessel were ancient electric batteries and even demonstrated that they can produce a small electric current when filled with some liquids. However, it is not likely that the vessels were actually used as electric batteries in ancient times.
First of all, if the vessels were used as batteries, they would probably have been attached to some electrical conductors such as metal wires. But there is no evidence that any metal wires were located near the vessels. All that has been excavated are the vessels themselves.
Second, the copper cylinders inside the jars look exactly like copper cylinders discovered in the ruins of Seleucia, an ancient city located nearby. We know that the copper cylinders from Seleucia were used for holding scrolls of sacred texts, not for generating electricity. Since the cylinders found with the jars have the same shape, it is very likely they were used for holding scrolls as well. That no scrolls were found inside the jars can be explained by the fact that the scrolls simply disintegrated over the centuries.
Finally, what could ancient people have done with the electricity that the vessels were supposed to have generated? They had no devices that replied on electricity. As batteries, the vessels would have been completely useless to them.
The reading and the lecture are about the ancient objects, clay jars, found in Iraq, which is supposed to generate electricity and have been a kind of battery. The author of the reading provides three reasons to refute this possibility. The lecturer, on the other hand, casts doubt on these claims and rebuts all the arguments which are mentioned in the passage.
First, the author asserts that there is no electricity conductor attached to the vessels to be used as a battery. It is mentioned that if the jar could be an electricity generator, it should have something like a metal wire. The lecturer, however, challenges this idea. She says that the mentioned objects have found by the local people so it would be plausible if they might overlook those attachments since they thought that those objects weren't valuable or even interesting.
Second, the writer states that the jar's copper cylinders are similar to some cylinders objects found in the ruined town nearby the place that the jar has found. As the copper objects in the ruined town were used to hold sacred text, the function of this recent jar might be the same. The professor, on the contrary, posits that this similarity doesn't prove anything since it would be possible that the ancient people changed their function later and used them as a device to generate electricity.
Third, the author contends that, in that time, there was no device working with electrical power so the battery was a useless object. The professor rejects this argument by saying that the ancient battery could generate a mild shock when someone touched it so it could be used as an invisible, magic power. Besides, the ancient doctors could use it to massage the muscles for different purposes.
