Astronauts on the International Space Station (ISS) may soon be able to turn their used forks and knives into tools and satellite parts.
Tethers Unlimited Inc. , an aerospace technology company, has developed a system that combines a waste recycling machine with a 3D printer.
Astronauts will put waste items made of plastic into the recycling machine, called the Poistrusion Recycler. When they press a button, the Recycler will melt down the plastic and turn it into 3D filament (长丝).
The filament will be used in a 3D printer on the ISS—called the Refabricator—to make tools, spare parts and satellite components.
The waste will come from packaging materials, food containers, trays and eating utensils (器具) used on the ISS. Astronaut currently use disposable wet wipes to clean their food containers and utensils. The used wipes are stored as trash (垃圾), and replacement wipes must be sent up to the ISS on cargo missions.
By recycling old food containers and utensils, astronauts will reduce the amount of trash they produce. To get rid of trash from the ISS, astronauts load it into empty cargo capsules (航天舱) and release it into space. The capsules burn up when they enter Earth’s atmosphere.
Turning trash into useful new items will also help NASA save money because astronauts will need fewer supplies. It costs about $ 6,000 for every kilogram launched into orbit. These benefits will be even more important for longer missions in the future—such as the twoyear journey to Mars. Astronauts will be able to recycle old waste materials into new tools and parts as they need them.
Tethers have successfully tested the systems in its laboratory. They will test it on the ISS in late 2018. The company is also developing a version of the system for use here on Earth.
[语篇解读] 本文讲述一家航天科技公司Tethers Unlimited Inc. ，开发了一种将废物回收机和3D打印机结合起来的系统。这种新技术可把塑料废物回收并转化为新的工具和部件，这不仅减少了宇航员们在空间站的垃圾量，节省了资金，还为探索空间提供更多的条件。
1.What material are the forks and knives for astronauts made of?
A.Gold. B.Iron.
C.Plastic. D.Wood.
答案：C [推理判断题。根据文章前四段可知，在国际空间站的宇航员把他们用过的刀叉回收变成工具和卫星部件，这种技术就是利用一种叫3D打印机和废物回收机相结合的系统，把塑料废弃品放入机中，回收后制成新的工具和部件。由此可知这些东西就是用塑料废物制成的。A.Gold. 黄金;B.Iron. 铁;C.Plastic. 塑料;D.Wood. 木头。]
2.At present, the astronauts mainly get supplies by ______.
A.D printers B.reusing the old ones
C.collecting from the space D.the capsules launched from the earth
答案：D [推理判断题。根据第六段To get rid of trash from the ISS，astronauts load it into empty cargo capsules(航天舱)and release it into space. 内容可知，空间站的货物航天舱(capsules)是用于与地球交流物质的。第七段Turning trash into useful new items will also help NASA save money because astronauts will need fewer supplies. It costs about $6,000 for every kilogram launched into orbit.... 可知将垃圾循环为有用的新物品，这有助于NASA节省资金，因为宇航员将需要更少的补给。由此可知宇航员所用的东西来源于地球，由于这项技术，可以少从地球带东西。由这两处可知只有D项正确。]
3.What can the new technology help the astronauts do?
A.Reuse the trash.
B.Send the trash to Mars.
C.Take the trash to the earth.
D.Load the trash into empty capsules and throw it away.
答案：D [根据第六段中的最后To get rid of trash from the ISS, astronauts load it into empty cargo capsules (航天舱) and release it into space. The capsules burn up when they enter Earth’s atmosphere. 可知，这段技术可帮助宇航员把垃圾倒进航天舱并扔掉。 ]
4.What is the biggest benefit of the new technology mentioned in the text?
A.It can save some space for the ISS.
B.It can gave more time for the astronauts.
C.It can provide more conditions to explore space.
D.It can help to reduce the journey from Earth to Mars.
答案：C [推理判断题。根据文章第六段可知这种新技术可把塑料废物回收并利用。减少了宇航员们在空间站的垃圾量。第七段可知，同时也有助于NASA节省资金，因为宇航员将需要更少的补给，让他们可进行更长久更远的宇宙旅行等。由这两处可知它可以为探索空间提供更多的条件。]
