阅读《中国皮影戏》,完成问题。

中国皮影戏

  ①皮影戏,是一种用灯光照射兽皮或纸板做成的人物剪影以表演故事的民间戏剧。表演时,一般由三到五个艺人在白色幕布后面,一边操纵戏曲人物,一边用当地流行的曲调唱述故事,同时配以打击乐器和弦乐。

  ②中国皮影戏有着悠久的历史。两千多年前,汉武帝爱妃李夫人染疾故去,武帝思念心切,神情恍惚,终日不理朝政。术士李少翁一日出门,路遇孩童手拿布娃娃玩耍,影子倒映于地,栩栩如生。李少翁心中一动,用棉帛裁成李夫人影像,涂上色彩,并在手脚处装上木杆。入夜围方帷,张灯烛,恭请武帝端坐帐中观看。武帝看罢龙颜大悦。这个载入《汉书》的爱情故事,被认为是皮影戏最早的渊源。

  ③表演皮影戏要先制作皮影。其制作过程是:先将羊皮、驴皮或其他兽皮的毛、血去净,经药物处理,使皮革变薄,呈半透明状,涂上桐油,然后把皮革镂刻成所需的人物形象。皮人的头、四肢、躯干等各自独立,而又用线连成一体,分别以连杠由演员操纵,令其活动。

  ④皮人涂有各种颜色,表达人物的善恶美丑。绘画也有一定的讲究,女性发饰及衣饰多以凤、花、草、云等纹样为图案,男性则多用龙、虎、水、云等纹样。人物造型与戏剧人物一样,生、旦、净、丑角色齐全,制成的皮影高的达55厘米,低的仅有10厘米左右。

  ⑤皮影戏表演时,由三五个艺人在白色幕布后面,一边操纵戏曲人物,一边用当地流行的曲调唱述故事,同时配以打击乐和弦乐。表演民间神话、武打、古代故事时,人物可以腾云驾雾,做出各种高难动作。这是其他戏剧难以做到的,因此深受观众喜爱。皮影戏在宋代已极为盛行,到明代,北京一带的皮影戏班竟达到四五十家。

  ⑥皮影戏是一门结合了戏剧、音乐等多种艺术表现手段的表演形式,它有着悠久历史,也是最早传入西方的中国传统艺术之一。

  ⑦公元13世纪,当时的蒙古军营中也演皮影戏,后来皮影戏被随军带到波斯、土耳其等国。之后,又在东南亚各国流传开来。中国皮影戏18世纪中叶传到欧洲。1767年,法国传教士把它带回法国,并在巴黎、马赛演出,被称为“中国灯影”,曾轰动一时。后经法国人改造,成为“法兰西灯影”。中国皮影戏对丰富世界艺坛作出了独特的贡献。

While the ripples of America’s subprime-mortgage crisis have spread far and wide, Latin America—a place long associated with financial disaster—has remained improbably calm. Banks have reported no unpleasant surprises. Brazil and Peru have been blessed with coveted investment-grade ratings. Surprisingly, perhaps the fleetest country of all has been Argentina. Since it emerged from the financial crisis of 2001-02, it has been one of the world’s fastest-growing economies. It is expected to expand faster than most of its neighbors again this year.

Quite simply, it barely has any credit. Back when its economy virtually collapsed, the country suffered a run on its banks, followed by a freeze on withdrawals, and a massive currency devaluation. As a result, bank lending to the private sector shrivelled, from 23.8% of GDP in 2000 to 10.8% in 2003. Since then, it has rebounded to a piddling 13% ; by contrast, the ratio in Brazil was 36.5% in 2006. Almost all of these loans in Argentina are accessible only on a short-term basis.

Once its recovery began in June 2002, Argentina became a paradise for business. Unemployment of over 20% kept wages down, and the devaluation gave exporters an edge on foreign competitors. The ample productive capacity left idle by the crisis meant firms could expand without making big investments. And the windfall profits reaped by agricultural exporters, thanks to record commodities prices, enabled many of them to finance new projects out of earnings. Hence the economy could grow at almost 9% a year with little need for credit.

But such a lucky confluence of factors could not last. Starting in early 2005 ,.inflation picked up, a sign that the installed capacity was starting to limit output. Salaries and prices for raw materials increased sharply, cutting into profits. And farmers were particularly hard hit when the government nearly doubled the taxes in farm exports. Now, just as companies need to embark on big investments if they are to keep growing, their margins are no longer big enough to pay for the expansion and they need to borrow.

So, the time is ripe for the country’s financial system to recover. But a number of things are in the way. Foremost is Argentina’s business risk. Those in the informal economy (which represents over 40% of GDP) can neither save nor borrow legally, lest they become known to the taxmen. The rest remain cowed by memories of the crisis. Although Argentines have poured their savings into property, fuelling a construction boom, they still hold about four-fifths of their deposits abroad.

Inflation, fuelled by a public-spending binge, state-mandated wage increases, and a cheap currency, is not helping either. No one knows how high it is. The consumer-price index is doctored to keep the official rate below 10%, but private estimates suggest it is near 25%. Without a reliable index of inflation, lending is almost impossible, even for the medium term. And the central bank has kept interest rates ply negative in real terms, encouraging workers to spend their wages rather than to save.

It can be inferred from the first paragraph that()

A. Latin America has been greatly influenced by America’s subprime-mortgage crisis

B. Latin America is suffering a financial disaster

C. Argentina has suffered a financial crisis at the beginning of this century

D. Argentina’s economy grows faster than any other countries’ economy
