1.听写包 答案：

listen to part of a lecture in an art history class.

Okay. So, when we were discussing Gainsborough’spainting, the Blue boy, which he painted in 1770,
I mentioned the story that the painting might’vebeen an experiment, the result of a challenge.
It was believed that blue couldn’t be an importantcolor in a painting
because...well...it tends to recede into thebackground, not good for your main subject, right?
So to show otherwise, Gainsborough created the BlueBoy, with the boy featured large in his famous blueclothes...and...well...I guess he proved his point.
But there was another challenge to blue, it was very very expensive back then.
Now of course, because of modern chemistry, any color is available in tubes at any art supplystore.
But in the 18th century and before, it wasn’t so easy.
And blue...well...the color ultramarine, the most desired shade of blue, was made from theprecious stone, Lapis Lazuli,
which had to be imported all the way from Afghanistan.
And the second most favorite shade of blue, after ultramarine made from Laps Lazuli, was ashade a blue that came from another precious stone, Azurite.
But Azurite was...well...harder to work with, there’s evidence that artists would try to getaround these difficulties.
For example, use pigment from lapis lazuli or azurite very sparingly, and also use somethingcheaper, like smalt, which was made of ground glass.
Thing is, smalt became discolored over time, so many artists probably avoided blues altogetherrather than use something cheap and impermanent.
请听艺术史课上的部分内容。
我们在讨论Gainsborough1770年画的作品Blue boy时，
我提到过这幅画可能是一个试验，一个挑战的结果。
那时的人认为蓝色不能成为一幅画中的一个重要颜色，
因为它往往会融进背景中，对你的主要人物不好，对吗？
所以为了证明他们是错的，Gainsborough创作了这幅Blue boy，画中的小男孩的很大特色在于他那件著名的蓝色衣服......我想他证明了他的观点。
但是那时蓝色还面对着另一个挑战，在那个时候蓝色非常非常昂贵。
现在当然了，多亏了现代化学，在任意美术用品商店都能买到管状的所有颜色。
但是在18世纪及之前并没有这么简单。
蓝色......深蓝色是最合适的蓝色阴影色，这种颜色是用一种珍贵的石头——天青石制成的，
而这种石头要从阿富汗一路进口过来。
排在用天青石制成的深蓝色之后的，第二最受喜爱的蓝色阴影色取自另一种珍贵的石头——孔雀石。
但是孔雀石更难使用，有证据显示画家会试着避开这些困难。
比如非常节约地使用提取自天青石或孔雀石的颜料，还有使用更便宜的颜料，比如大青色，一种由钴玻璃制成的深蓝色。
问题是，大青色时间久了会掉色，所以很多画家可能会全部避免。
