【分析】
这是一篇说明文。有房子住是人类的基本需求,但是世界上还有 12 亿人没有足够的住房,而一种革命性的、低成本的 3D 打印机可能可以改变这种情况。文章主要介绍了这种 3D 打印房屋的技术和未来发展情况。
1. 考查连词。句意:有房子住是人类的基本需求,但是世界上还有 12 亿人没有足够的住房。上文提到 “ 有房子住是人类的基本需求 ” ,后文则说 “ 世界上还有 12 亿人没有足够的住房 ” ,前后为转折关系,应用连词 but 。故填 but 。
2. 考查介词。句意:这种情况可能会改变,这多亏了一种革命性的、低成本的用来建造公寓的 3D 打印机。结合句意表示 “ 多亏了 ” 可知短语为 thanks to 。故填 to 。
3. 考查名词的数。句意:这种情况可能会改变,这多亏了一种革命性的、低成本的用来建造公寓的 3D 打印机。 apartment 为可数名词,此处前文没有冠词,表示数量大于一应用复数形式。故填 apartments 。
4. 考查固定短语和时态。句意:这些房子完全以新技术为基础。结合句意表示 “ 以 …… 为基础 ” 可知短语为 be based on ,句子陈述客观事实用一般现在时,主语为 houses ,谓语动词用复数。故填 are based 。
5. 考查副词。句意:两家官方公司已经加入进来,试图通过 3D 打印来逐步帮助世界各地的无家可归者。修饰动词 help 应用副词 gradually ,作状语。故填 gradually 。
6. 考查动词时态。句意:到目前为止,科技公司 ICON 已经开发出一种每天打印 60 平方米一层房子的方法,只需 1 万美元。根据上文 “Up to now” 可知用现在完成时,主语为 tech company ICON ,助动词用 has 。故填 has developed 。
7. 考查定语从句。句意:希望它能形成一些这样的房子,这对非洲国家或东方国家特别有用。此处为非限制性定语从句修饰先行词 this kind of house ,先行词在从句中作主语,指物,故应用关系代词 which 引导, that 不能引导非限制性定语从句。故填 which 。
8. 考查形容词。句意:希望它能形成一些这样的房子,这对非洲国家或东方国家特别有用。根据上文 is 可知应用形容词 useful ,作表语。故填 useful 。
9. 考查非谓语动词。句意:他们的合资企业明年将建成 100 套新房。此处为 “see+ 宾语 + 宾补 ” 结构, homes 与 construct 构成被动关系,故用过去分词作宾补。故填 constructed 。
10. 考查非谓语动词。句意:有超过 1 亿生活在贫困条件下的人。分析句子结构可知 live 在句中应用非谓语动词形式,与逻辑主语 people 构成主动关系,故用现在分词作定语。故填 living 。
