04、荷兰团队是如何用3D打印造出全尺寸房子的？How is Dutch team 3D-printing a full-sized house？
03/05/2014
Architects in Amsterdam have started building what they say as Europe's first full-scale 3D-printed house. They claim it's a waste-free， ecofriendly way to design our cities in the future. Forget bricks， tiles and wooden beams. If you want to build a house in future， it may only require the fresh plant oil or discarded plastic bags and a rather large 3D-printer. We've come to see what appears to be the ultimate do-it-yourself project. Inside a small courtyard in north Amsterdam lie the first skeletal structures-a black plastic facade and a few steps. These are the first tangible pieces according to the blueprint. Eventually， they will create a five-story canal house. So we are now inside the KamerMaker which translates as room builder. It's built inside a huge shipping container. And this also means when they want to transport the technology to cities like Lagos or Mumbai， they can simply move it around and then use locally sourced material for the building products. And here we have the latest part of the Amsterdam 3D house. This will be the roof balcony. And the architects say that this is the most sustainable technology for building the homes of the future.
Over half of the world population is really now living in cities and still and sometimes in fairly poor conditions.
Back in the courtyard， a 3D-printed couch is designed to invite visiters to engage with the concept. Sitting down on the rather comfortable， if slightly unconventional couch， it demonstrates that traditional furniture can come from the most modern technology. The architects hope it will help people to recognize the ecofriendly possibilities and inspire the next generation to imagine alternative methods of construction.
Soon everything could be 3D-printed.
It might even start creating metal 3D-printer. People could use it to make furniture.
Therefore，（they）allow us to live without chopping down trees.
译文：
阿姆斯特丹的工程师正在着手打造他们说的欧洲首栋3D打印房屋。据工程师们说，该房屋是无浪费的生态友好型房屋，是设计未来城市的典范。砖块、瓷砖、木梁，这些都不用。如果将来你想盖房，只需要新鲜的植物油或废弃的塑料袋，以及一台超大的3D打印机。我们来看看这项无与伦比的自己动手做（DIY）的项目。在阿姆斯特丹北部的一个小院子里，有3D房屋初步的杆系结构——黑色的塑料外观和几个台阶。这是根据蓝图制作的首批有形结构。他们最终将会形成5层的运河房屋。我们现在是在KamerMaker里面，翻译为“房屋建造者”。它被安装于一个巨大的集装箱里。也就是说，如果想把这项技术运到拉各斯、孟买等城市，只需将集装箱运到那里，然后运用当地的材料建造房屋。我们现在看到的是阿姆斯特丹3D房屋最新完成的部分——屋顶阳台。工程师说，这是未来建造房屋最具可持续性的技术。
世界上超过一半的人口住在城市里，而且有的居住环境十分简陋。
回到院子里，我们可以看到一个3D打印沙发，用来使参观者切身体会这个理念。坐在这个有些非常规的沙发上很舒服，它向人们证明了传统家具也能来源于最现代的技术。工程师们希望这个沙发能帮助人们意识到生态友好的可能性，同时，鼓励下一代想象未来建造房屋的新方法。
很快，所有东西都可以通过3D技术打印出来。
人们很有可能会发明金属3D打印机。人们可以用它来制造家具。
所以，不用砍树我们就能住上房屋。

05：作曲家门德尔松“失踪”作品重现'Lost'Mendelssohn song re-discovered
06/05/2014
A song written in 1842 by the German composer Mendelssohn lost for nearly 150 year has been found among the papers of a musician in America. More details from Rebecca Jones.
You are listening to music that no one has heard for nearly 150 years. Mendelssohn wrote this song in 1842. It was a private commission and the manu was never published. And it's been played first by the pianist Christopher Glin and the singer Amy Williamson from the Royal College of Music.
What's your reaction to hearing this for the first time？
Well， it's lovely to hear it and beauti-fully sung. It's a very short song， very simple， not at all elaborate yet， very effective. And Mendelssohn like all great composers， in addition to writing intricate works， could also write very straightforward masterpieces， which are nevertheless very expressive. I mean， all composers have their better days and off days， but this is certainly not one of Mendelssohn's off days.
What do we know about how the song came to be written？
We know quite a lot about its history in that it was written at the specific request of an acquaintance of his in Berlin in 1842.
We are having a look at the manu- now.
It's just a single page manu， but at the end， it has this inion by Mendelssohn with his customary wonderful signature. And Mendelssohn's signatures are work of art in themselves.
So that's how we can be sure that this is genuinely by him.
It is in fact genuine. That's right. And there is also with the manu a little letter that Mendelssohn wrote a few days later. And the letter is significant because it make.
