第二次世界大战的爆发是以哪国于哪年哪月哪日袭击哪国为标志的？

守旧还是创新一直是个争论不休的话题，前者的基础往往在于“传统文化的保持”，后者的起点在于“不发展就没有前途”，这种矛盾近年来在法国的葡萄酒行业中表现得很明显，法国葡萄酒行业为了保持几百年的葡萄酒生产传统，坚决不肯进行产业改造，工艺、包装、口味一直沿袭固有，但投放到市场上，消费者却不买账，因为太高的制作成本让多数人对这种“高贵”葡萄酒敬而远之，反倒是没有任何文化底蕴的“速食”葡萄酒颇受欢迎。我们或许没有理由来责怪这些消费者的浅薄，因为对于他们来说，喝酒是为了“味蕾”而不是“精神”，但从长远来看，正是这种物质享受的后果导致了很多传统文化的衰落与沉没，中国的武术也同样正面临着这样的困境和危险。
最能准确复述这段话意思的是( )。

A．法国的葡萄酒行业正在被新的酿酒工艺所侵袭，正在不断地走向没落

B．守旧与创新是并行不悖的，只是要在不同的时候有不同的侧重

C．虽然守旧与创新在不断争论，但事实上如果仅是为了物质消费而创新的话，会出现传统文化没落的危险

D．中国的武术和法国的葡萄酒一样，都将因为过于坚持传统而逐渐失去市场最终衰落沉没

SEE a cell phone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hit­ting "print" on your computer.

You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to under­stand how it would work. Just as a traditional printer sprays (喷) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.

Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (树脂)and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair ---  the smoother and finer the object will be.

This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.

Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now they cost only about £ 1,000, according to the BBC.

Taken out of the factory and in­troduced to more diverse and com­mon uses, 3-D printing can create just about anything you can think of ---flutes (笛子), bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell Univer­sity in New York have just made an artificial ear using a 3-D printer, accord­ing to Science Daily. The fake ear looks and acts exactly like a natural one.

However, as 3-D printing becomes more commonplace, it may bring about certain problems --- such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun?
