Day 43
2月17日
TPO 7 听力
对话
志愿者 错1对4
图书馆 错0对5
讲座
蝙蝠超声波 错1对5
易洛魁人 错1对5
剧院历史 错3对3
冰川运动 错2对4
这次的两个对话都是很高频的内容,没啥大问题。四个课程里,剧院那篇有些专业内容不懂,背景不熟悉。冰川那篇又讲了一堆抽象的内容,听起来也比较费劲。还是有具体的故事情节的东西比较好懂。
需复习的长句
The answer that some give is that their behavior has evolved over time: it’s been shaped by constraints over vast stretches of time, all of which comes down to the fact that the best foraging strategy for beavers isn’t the one that yields the most food or wood: it’s the one that results in the most descendants, the most offspring.
In the early 1100s, a church-building method was developed that reduced the stress on the walls, so more space could be used for window openings--allowing for large and, and quite elaborate window designs.
And, and it's different because with painted glass the idea of light coming through to create the magic effect wasn't the focus anymore... the paint work was.
Now, uh, in the window itself, the pieces of glass would be held together by strips of lead, so in the drawing, the uh artist would also indicate the location of the lead strips.
Well, lead is strong and, and flexible so it is ideal for joining pieces of glass cut in different shapes and sizes.
Uh but luckily there was a revival of the early techniques in the mid-1800s, and, and artists went back to creating colored glass and using the lead strips in their designs.
These of course took advantage of the new innovation of electric lighting e-electric lightbulbs don't give quite the same effect as sunlight streaming through stained glass, but it's close.
Up until now in our discussions and readings about the Baroque early Classical periods, we’ve been talking about the development of musical styles and genre within the relatively narrow social context of its patronage by the upper classes.
Now, as we know, keyboard instruments existed long before the piano—the organ, which dates back to the Middle Ages, as do other keyboard instruments, such as the harpsichord, which is still popular today with some musicians.
Previously, it was uh, quite rare for a woman to perform on anything but maybe a harp, or, or maybe she sang, but suddenly, in the nineteenth century, it became quite acceptable—even, to some extent, almost expected—for a middle-class European woman to be able to play the piano… partly because, among upper-middle-class women, it was a sign of refinement, but it was also an excellent way for some women to earn money—by giving piano lessons.
Well, the percussive effect of those little hammers means that the pianist, unlike the harpsichordist, can control the dynamics of the sound—how softly or loudly each note is struck—hence the name pianoforte—“soft and loud.”
Now, there are some pretty interesting caves in parts of the western United States, especially in national parks; there’s one park that has over a hundred caves, including some of the largest ones in the world.
Well, that might be a bit of an exaggeration, but it’s safe to say that it’s sulfuric acid, and not moving water, that formed Lechuguilla Cave, and those few other ones like it
It’s not really forming anymore… but there’s other ones like it, for example in Mexico, that are forming, and when cave researchers go to explore them, they see—and smell—the sulfuric acid and gases at work.
This is part of what led us to the realization that Lechuguilla is in that small group of waterless caves.
