根据短文理解，完成下列各题。

      Before the spring Festival, which is the most important festival in China, millions of passengers are struggling to make the once-a-year trip home. Because of a power failure caused by snow, more than 136 trains were forced to stay in Hunan Province. Almost 150,000 passengers were stopped from going back their homes. It's reported that the losses will be 111.1 billion yuan.  

In central China's Hunan Province, one of the worst hit area, seven people have died and snow is affecting（影响） the lives of 25.22 million people in 14 cities and 112 counties across the province. Though the power supply resumed(恢复) at 4:00 p.m. Saturday, 50 trains remain stranded (滞留) between Hengyang City in Hunan and Guangzhou provinces. And in Guangzhou, an official with Guangzhou railway authorities said the number of stranded passengers in Guangzhou City alone could hit 600,000 on Monday if the situation continued.

How to solve the problems as soon as possible? In order to help the passengers meet their families and solve the traffic problems, our government do what they can. First, The Ministry of Railways Ordered 63 trains to go to Guangzhou via (通过) the Beijing-Kowloon Railway Line or Shanghai-Kunming Railway Line instead of the Beijing-Guangzhou Railway Line. Second, the ministry also organized 35 trains from Beijing, Wuhan and Nanchang cities to help transport the stranded passengers. The thirdly, Guangdong authorities sent 15 million text messages (短信)warning drivers not to take highways leading north. Some Guangzhou citizens try their best to help the stranded passengers, such as offering medicine, raising money and cooking free meals for the stranded students.

      The snow disaster(雪灾) is so terrible, but all of the Chinese and government is trying their best to succeed in beating it.

锔瓷技艺

       ①锔瓷，是指陶瓷器修补技术。

       ②中国是瓷器的发源地。瓷器光亮圆润、坚固耐磨，因而广泛用于日常生活。但瓷器易碎，且无法通过粘合或捆绑复原。在生活水平底下的年代，市场有碎瓷再生的需求。同时瓷器可制成工艺品，有的晶莹剔透，有的大器沉雄。这些作品往往出自于大师之手，不可重复，不得再生，只有修补。于是，锔瓷技术便应运而生。

       ③锔瓷需要金刚钻，因为瓷器的硬度非常高，其它金属钻头都无法钻孔打眼，所以民间有“没有金刚钻，别揽瓷器活”的说法。

       ④锔瓷讲究精工细作。比如紫砂壶的锔补，因为壶壁较薄，锔钉眼的深度要控制在壶壁的一半，这种精确到毫米的工作，完全靠工匠的手感。用力稍欠，深度不够，则事倍功半；用力稍过，壶壁钻透，则前功尽弃。再如形似订书钉的“锔钉”，两只脚打入钉眼时角度要好，否则难看不说，天长日久就走形了。

       ⑤在将碎瓷修补完好的基础上，如何使这些再生之器看得上眼，就要讲点艺术了。因为单纯的修补只是匠活，而修复却不觉丑陋，再生而没有缺憾，就接近艺术了。乾隆年间兴起的“锔活秀”，要求锔匠们在修补瓷器时，重视对器具的装饰，能将镶嵌、锻打等工艺融入锔补拼接中。于是对瓷器进行镶边、雕花、包口、刻字等修饰工艺便产生了。

       ⑥“锔合以道”是这项技艺的顶峰，碎瓷的每一条裂纹，每一道缝隙都有它的走势和趋向，工匠的匠心在于通过艺术构思，运用精湛的手艺，在残缺的器物上完成二次创作，此时的作品雅性自然：破碎的纹路或直或斜，亦曲亦直，状如枝蔓，形似闪电，自然而生，看似有为却若无为，从而达到“补而不失其真，修而愈增其美”的化境。

       ⑦锔瓷技艺的起源已无法考证，但《清明上河图》描绘了锔匠做活的一幕，可见他至少跨越了千年历程。锔瓷是一门成人之美的手艺，每一次成功修复破损的物件，就像是修复一份破碎的感情，但社会在前进，伴随着中国工业化的发展和人民生活水平的提高，锔瓷技艺日渐式微，昔日串街走巷的锔瓷工匠，已经淡出人们的视野。
