Transient lunar phenomena (TLP) are relatively brief flashes of light that appear to come from the surface of the Moon. Such flashes of light have been observed for centuries by both amateur and professional astronomers, and several theories have been put forward to explain them. One theory is that TLP are not genuine lunar phenomena, but only random observational errors caused by defects in the telescopes some observers use. Optical instruments such as telescopes or microscopes are complex pieces of machinery; even small flaws in their design can create artificial optical impressions like flashes or other distortions in the visual field. To an observer, a flash of light caused by an instrument error may sometimes look like a real phenomenon taking place in nature. A second theory is that meteors striking the Moon cause TLP. Because the Moon has no atmosphere, meteors often reach the lunar surface. In fact, meteors strike the Moon every day. According to the meteor theory, when meteors strike the lunar surface, they explode, creating enough heat energy to appear as a flash of light to observers on Earth. When people observe TLP, they are actually observing flashes of light generated by meteor impacts. A third theory is that TLP are the result of lunar rocks emitting their own light by a process called thermoluminescence. It is known that the Moon does in fact contain certain rocks that are capable of generating light in this way when they are heated by the Sun. This is strong empirical support that TLP are caused by thermoluminescence.

In the reading, the author proposes three possible explanation for TLP. However, the listening argues that none of these explanations are able to explain TLP, and opposes the points in the reading material. First and foremost, the author argues that TLP are random observational errors caused by the optical equipments. However, the speaker rebuts that if TLP are random errors, the reports and the places where people observe the TLP should also be random. However, the observed TLP are always associated with two specific location, which indicates that TLP is real happening on the Moon. In addition, the speaker casts doubt on the author's second viewpoint that TLP are resulted from the meteors striking; the speaker also demonstrates that the light generated by metors striking normally lasts one second, whereas the avergae duration of TLP is twenty minutes. Moreover, the vast majority of TLP do not appear with metors shower. Therfore, TLP must have other causes. Finally, in the reading, it is said that the light emitted by lunar rocks contribute to TLP. On the other hand, the speaker points out that the light from lunar rocks are much weak if we observe it on the Earth. Furthermore, moonlight are reflacted from the sun, which is much brighter than thermoluminescence, and thus we are unable to see thermoluminescence at that kind of background. Therefore, the thermoluminescence is not the source of TLP.

示例1： 原文：“However, the speaker rebuts that if TLP are random errors, the reports and the places where people observe the TLP should also be random.” 改进：“However, the speaker rebuts that if TLP were caused by random errors in telescope design, we would expect to see reports of TLP occurring at various random locations on the Moon's surface. Instead, most observers report TLP from two very specific locations on the Moon's surface, suggesting that they are real events happening on the Moon rather than flaws in telescopes.”
示例2： 原文：“Therfore, TLP must have other causes.” 改进：“Therefore, while it is possible that a few TLP are caused by meteor impacts, the great majority of them must have other causes.”

Section Title: 6.文章修订
The reading passage presents three possible explanations for Transient Lunar Phenomena (TLP), while the lecture challenges each of these theories, asserting that none of them adequately account for TLP.
Firstly, the reading suggests that TLP may be random observational errors caused by defects in optical equipment. However, the lecture counters this argument by stating that if TLP were merely random errors, the reports and locations of observed TLP should also be random. Instead, TLP are consistently associated with two specific locations on the Moon's surface, indicating that they are genuine lunar events rather than telescope flaws.
Secondly, the reading posits that meteors striking the Moon could cause TLP. The lecture disputes this theory by explaining that light generated by meteor impacts typically lasts only one second, whereas the average duration of a TLP is twenty minutes. Furthermore, most TLP are not reported during meteor showers. Thus, while some TLP may be caused by meteor impacts, the majority must have other origins.
Lastly, the reading proposes that thermoluminescence from lunar rocks could be responsible for TLP. In contrast, the lecture argues that light emitted by lunar rocks is too weak to be observed from Earth and would be overshadowed by sunlight reflected off the Moon's surface. As a result, thermoluminescence cannot be considered as a viable source for observed TLP flashes. (223 words)
