Q1.
Reading
Numerous astronomers over the years have reported seeing brief changes in the color or brightness of small areas of the Moon from time to time. Known as transient lunar phenomena, or TLPs, the cause of these events is the subject of a number of interesting and plausible hypotheses. One possibility is that clouds of lunar gas are causing the phenomena. Many researchers believe that gases beneath the surface of the Moon are occasionally expelled into the thin lunar atmosphere. The resulting gas clouds are visible from Earth as reddish or white hues. This theory is consistent with the fact that most TLPs are seen in the vicinity of craters with large fractures, where the gas would be able to escape to the surface. In fact, a probe sent by NASA to the Moon detected the emission of radon gas in the vicinity of Aristarchus, a lunar crater where many TLPs have been observed. Next, some experts believe that TLPs are illuminated clouds of dust floating above the lunar landscape. They posit that particles from space strike the Moon's surface, causing lunar dust to levitate above the ground. Light is then reflected off the suspended dust, creating glows that are visible from Earth.
A third theory holds that TLPs are caused by solar radiation. Occasionally, magnetic storms on the Sun's surface release intense bursts of radiation called solar flares, and it is argued that these flares can illuminate portions of the Moon's surface.
Many astronomers have reported a greater incidence of TLPs during the peak of the solar cycle when the highest number of flares is emitted, a fact that strongly supports the solar flare hypothesis.

As you know, transient lunar phenomena are a pretty hot topic these days. Now, you've read some theories about what's behind TLs, but do any of these ideas really explain why these events occur? Unfortunately, I think the answer is a clear "no." One important point I'd like to make is that gases are unlikely to be responsible for TLPs. For one thing, it's almost certainly a coincidence that most TLPs are observed near lunar craters where gases leak out. You see, as those craters are the most frequently observed features of the Moon, it's no wonder that most TLPs are seen near them. And what about the probe that detected radon gas near a TLP site? Well, it's not actually known how much gas was being emitted there. It may have been only a small amount of gas that couldn't be seen from Earth.
As for the idea that TLPs are caused by dust, there just isn't any evidence for that. In order to be visible from Earth, dust clouds would have to be very, very large ... huge dust storms, essentially. But there's never been any real indication that such storms occur on the Moon. In fact, we've got solid evidence that there's actually very little dust floating around. Specifically, uh, Apollo astronauts who walked on the Moon reported that flat rock surfaces were almost completely free of fine dust particles. Let's move on to the solar flare theory. This was a popular idea for a while, but it turns out that it was based on insufficient data. A recent study collected the dates of all observed TLPs and then systematically compared them with the dates of solar flares, and the results were surprising . . . Sometimes they matched up, but more often they didn't. There was actually no correlation at all between TLPs and solar flares.
Me:
The reading passages contends that brief changes in the color or brightness of small areas of the Moon can be explained by three theories: gas, dust and solar flares. On the other hand, the lecturer brings up several points that contradicts this argument.
First, the lecturer asserts that lunar gas is not responsible for this phenomena. He mentions that It could be just a coincidence that creators are observed near the Moon. Also, He states that the number of TLPs observed mentioned in the reading passage is known as very few cases. This casts doubt on the reading passage's claim that lunar gas would cause the phenomena.
Second, the lecturer contends that dust floating above the lunar landscape is not very visible. He posits that the incidence that particles from space strike the Moon's surface actually little occurs. This counter the reading passage's claim that lunar dust to levitate above the ground creates glows that are visible from Earth.
Finally, the lecturer points out that bursts of radiation called solar flares are not enough to impact on this phenomena. He maintains that there is no correlation between the TLPs and solar flares. This refute the reading passage's claim that TLP's are caused by solar radiation.
GPT:
Your response is mostly clear and well-structured, showing understanding of the key points from both the reading and the listening materials.
Here's a breakdown of the scores according to the TOEFL rubric:
Task Achievement: 3.5/4 - You successfully synthesized and integrated information from the reading and listening passages. However, there are some slight inaccuracies in the details you provided, such as the explanation regarding gas leakage near the craters and the number of TLPs observed.
Coherence and Cohesion: 3.5/4 - Your essay is generally well-organized with clear transitions between ideas. But, there is room for improvement in presenting your ideas in a more logical and smooth manner.
Language Use: 3/4 - While your language use is mostly accurate and you used a range of vocabulary and grammar structures, there are minor errors and awkward expressions that slightly hinder understanding.
Overall, I would give your essay a score of 10/12.
Now, here's a modified version of your essay:
The reading passage suggests three potential theories for the transient lunar phenomena observed on the Moon: emissions of lunar gas, levitation of lunar dust, and solar radiation. The lecturer, however, contradicts these theories.
Firstly, the lecturer disputes the idea of lunar gas causing the phenomena. Although the reading suggests that TLPs often occur near lunar craters due to gas expulsion, the lecturer believes this to be coincidental given that these craters are frequently observed areas of the Moon. Additionally, he indicates that the amount of gas released, as detected by the probe mentioned in the reading, may be insufficient to cause visible changes from Earth.
Secondly, the lecturer challenges the dust theory. He argues that for dust clouds to be visible from Earth, they would need to be extremely large, akin to dust storms. There is no evidence of such storms occurring on the Moon. The reading's claim that lunar dust levitates to create visible glows is therefore undermined.
Finally, the lecturer disputes the theory of solar radiation causing TLPs. Despite the reading's assertion that solar flares can illuminate parts of the Moon, the lecturer refers to a study demonstrating no correlation between the occurrence of TLPs and solar flares, thereby refuting the reading's claim."
I hope this helps, and keep up the good work!
Teacher:
The lecturer argues that none of the ideas explain why TLPs ouccr. This contradicts the reading passage's claim that the hypotheses about the cause of TLPs are plausible.
First, the lecturer suggests that lunar gases are unlikely to be responsible for TPSs. It is just a coincidence that most TLPs are seen near lunar creator because those are the most observed parts of the Moon. Moreover, maybe the gas detected by a probe was only a small amount of gas that could not be seen from Earth. This casts doubt on the reading passage's claim that lunar gases are causing TPS.
Next, the lecture explains that there is no evidence that dust causes TLPs. Huge dust storms would have to happen for the dust to be visible from Earth, but there is no indication of such storms occurring on the Moon. Huge dust storms would have to happen for the dust to be visible from Earth, but there is no indication of such storms occurring on the Moon. In addition, it was reported that rock surfaces on the Moon were almost free of fine dust particles. This counter the reading passage's claim that TLPs occur when dust clouds are lit up.
Finally, the lecturer claims that the solar flare theory was based on insufficient data. Researchers recently compared the dates of TLPs and the dates when solar flares occurred. They found that there was actually no correlation between the two. This refutes the reading passage's claim that radiation from the Sun triggers TLPs.
