文章大意：本文是A、B两个人的对话，他们在谈论一种叫做3D打印的新技术。如果有可能B说他想发明一辆会飞的自行车，以改善路上的交通压力。而A因为他妈妈长期坐在椅子上，总是背疼，所以他希望发明一把能帮助他妈妈的椅子。

【1】考查动词。根据上文 It wasn't here last weekend.它上个周末不在这里，结合How could anybody___1___ a toilet in a short time?可知句意为“怎么可能有人在这么短的时间内完成建造一个厕所的？”build建造，情态动词could后接动词原形，故答案填build。

【2】考查名词。根据下文That's why the cellphone prices are dropping so fast.这就是手机价格下跌如此之快的原因。结合It was printed by the 3D printer whose___2___has risen worldwide recently.可知句意为“它是由3D打印机打印出来的，它的价格最近在全球范围内都已经上涨。”price价格，这里是whose引导的定语从句，故答案填price。

【3】考查动词。根据It's a kind of new technology__3__3D print.可知句意为“它是一种被叫做3D打印的新技术。”call/name叫，动词，由句意可知这里指的是“被叫做”，所以应用过去分词called/named作定语，故答案填called/named。

【4】考查名词。根据You design what you want on the computer and then print it with certain__4__.可知句意为“你在电脑上设计你想要的东西，然后用某些材料打印出来。”material材料，certain material某种材料，故答案填material。

【5】考查副词。根据上文提到“当然可以打印手机。”结合__5__, many parts in the cellphone are printed.可知句意为“事实上，手机的很多部分都是打印出来的。”actually事实上，副词，修饰后面的整个句子，而且位于句首，首字母要大写，故答案填Actually。

【6】考查名词。联系上文I've heard of printing papers, printing shirts but I have never heard of printing a building. 我听说过印刷纸张，印刷衬衫，但我从未听说过印刷建筑物。以及It's a kind of new technology___3___3D print. 它是一种被叫做3D打印的新技术。结合I really admire the__6__. 可知句意为“我真的很钦佩这项技术（发明）。” technology/invention技术/发明，这里是特指，故答案填technology/invention。

【7】考查动词。根据下文On the other hand, it can prevent the environment being polluted, too.另一方面，它也可以防止环境被污染。结合I would like to invent a flying bike that can travel in the sky to__7__the heavy traffic on the road.可知句意为“我想发明一辆会飞的自行车，可以在空中旅行，改善路上的交通状况。”improve改善，动词，前面有动词不定式符号to，所以这里用动词原形，故答案填improve。

【8】考查形容词。根据That will surely become one of the most creative inventions in the__8__future. 可知句意为“在不久的将来，这肯定会成为最具创造性的发明之一。” in the near future在不久的将来，固定词组，故答案填near。

【9】考查动词。根据My mother sits in a chair for too long every day, 我妈妈每天坐在椅子上的时间太长了，结合so her back always__9__,可推知是她总是背疼，hurt疼痛，动词，由always可知句子时态是一般现在时，主语her back为第三人称单数，所以谓语动词也要用第三人称单数形式，故答案填hurts。

【10】考查短语。根据It can play some music to remind her when she needs to stand up and do exercise____10____in a while.可知句意为“当她时不时需要站起来做运动时，它可以播放一些音乐来提醒她。”once in a while时不时、间或、偶尔，故答案填once。
