小马公开课 小马公开课网址： bbs.xiaoma.com/gkk TPO18-3 Roman sculpture Now the dominant view in traditional art his that Roman artists lacked creativity and skill especially compared to the Greek artists who came before them. Essentially, the traditional view, a view that’s been prevalent for over 250 years, is that the Romans copied Greek sculptures because they couldn’t create sculpture of their own. But finally some contemporary art historians have challenged this view. One is Elaine Gazda. ①艺术性 Gazda says that there might be other reasons that Romans made copies. She wasn’t convinced that it was because of a lack of creativity. Can anyone think of another possible reason? Well maybe they just admired these sculptures. 1 ： You know, they liked the way they looked. Yes. That’s one of Gazda’s points.2 ： Another is that while nowadays reproduction is easy, it was not so easy in Roman times. Copying statues required a lot of skill, time and effort. So Gazda hypothesizes that copying didn’t indicate a lack of artistic imagination or skill on the part of Roman artists, but rather the Romans made copies because they admired Greek sculpture. Classical Greek statues represented an idealization of the human body and were considered quite beautiful at the time. ②政治性 Gazda also believes that it’s been a mistake to dismiss the Roman copies as, well, copies for copy’s sake and not to consider the Roman function and meaning of the statues.

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk What is the lecture mainly about? Different views of a type of sculpture popular in ancient Roman times Evidence that Romans had outstanding artistic ability The differences between Greek sculpture and Roman sculpture The relationship between art and politics in ancient Roman times

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk According to traditional art, why did the Romans copy Greek sculpture? The Roman public was not interested in original works of art. The Roman government did not support other forms of art. Roman artists did not have sufficient skill to create original sculpture. Romans wanted to imitate the art they admired

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk What is Gazda's view of the Roman copies of Greek statues? The copies represented the idea that Roman society was similar to Greek society. The copies introduced the citizens of the Roman Empire to Greek history. The copies were inferior to the original statues. The copies had both artistic and political functions.

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk TPO7-5: bats’ ultrasound Now, we’ve tended to underestimate just how sophisticated the abilities of animals that use ultrasound are. In fact, we kind of assume that they were filtering a lot out ， uh…the way a sophisticated radar system can ignore echoes from stationary objects on the ground. Radar does this to remove ground clutter, information about uh…hills or buildings that they doesn’t need. But bats, we thought they were filtering out this kind of information, because they simply couldn’t analyze it. But, it looks as if we were wrong. Recently there was this experiment with trees and specific species of bats, a bat called the lesser spear-nosed bat. Now, a tree should be a huge acoustical challenge for a bat, right? I mean it’s got all kinds of surfaces with different shapes and angles. So, while the echoes from a tree are going to be massive chaotic acoustical reflections, right, not like the echo from a moth. So, we thought for a long time that bats stop their evaluation as simply that’s a tree. Yet, it turns out that that bat ， at least this particular species, cannot only tell that is a tree, but can also distinguish between, say, a pine tree, and a deciduous tree, like a maple or oak tree, just by their leaves. And when I say, leaves, I mean pine needles too.

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk What surprising information did a recent experiment reveal about lesser spear-nosed bats? A.They filter out echoes from some types of trees B.They can analyze echoes from stationary objects with complex surfaces C.They cannot analyze "jagged" echoes D.They cannot analyze echoes from certain types of small moving objects.

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk TPO7-5 the role of spices also Now, this is a good point to mention one of the biggest myths about spices. It’s commonly said that medieval Europeans wanted spices to cover up the taste of spoiled meat. But this isn’t really true. ① Anyone who had to worry about spoiled meat couldn’t afford spices in the first place. If you could afford spices, you could definitely afford fresh meat. ② We also have evidence that various medieval markets employed a kind of police to make sure that people did not sell spoiled food, and if you were caught doing it, you were subject to various fines, humiliating public punishments. So what actually was true was this: In order to have meat for the winter, people would preserve it in salt, not a spice. Spices actually aren’t very effective as preservatives.

Click in the correct box for each phrase They had to be imported. They were unaffordable for many people. They were used to preserve meat during the winter. They were believed to have medicinal properties. Their sale in public markets was closely regulated.

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk TPO15-3 speculation Interestingly there's some speculation that humans started having a major impact on Earth much earlier, about 8000 years ago. That's when agriculture was becoming widespread. Early farmers started clearing forests and livestock produced a lot of extra methane. But I want to stress this is just a hypothesis. The idea that early humans could have had such a major effect, well I'm just not sure we can compare it with the industrial age. Geologists in the far future will be able t o examine the sediment being laid down today, whereas right now we can say that yes, human impact on the Earth is clear: It'll be future researchers who have a better perspective and will be able to really draw a line between the Holocene and the Anthropocene epics.

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk 推断题 What does the professor imply about the spread of agriculture 8,000 years ago? It was the true beginning of the Holocene epoch. It was when greenhouse gases were at their lowest levels It was not a major cause of population growth It did not cause as big an environmental impact as some researchers say

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk 态度题 What does the professor say about future researchers? They may not agree that humans have had an important effect on Earth’s surface They will not have reliable evidence of what is happening today They will determine when the Anthropocene epoch began They will make predictions about when the Anthropocene epoch will end

小马公开课 小马公开课网址： bbs.xiaoma.com/gkk TPO3-6 Spectroscopy I want you to know this that this spectrum is interrupted by dark lines called spectral lines. If you really magnify the spectrum of the sunlight, you could identify more than 100,000 of them. They may look kind of randomly placed, but they actually form many distinct patterns. And if you were looking at the spectrum of some other star, the colors would be the same. But the spectral lines would break it up at different places, making different patterns. Each pattern stands for a distinct chemical element, and so different sets or patterns of spectral lines mean that the star has a different chemical composition. So how do we know which spectral patterns match up with which elements? Well, a kind of spectroscopic library of elements was compiled using flame tests. A known element, say a piece of iron for example, is heated in a pure gas flame. The iron eventually heats to the point that it radiates light. This light is passed through a prism, which breaks it up into a spectrum. And a unique pattern, kind of like a chemical fingerprint of spectral lines for that element appears. This process was repeated over and over again for many different elements, so we can figure out the chemical makeup of another star by comparing the spectral pattern it has to the pattern of the elements in the library.
