Two companies, ICON and the non-profit group New Story, announced on their websites this week that they will start building affordable homes using 3D printing. 3D printers join materials together via a computerized device that creates 3Dobjects.Tech company ICON can make a one-floor house out of cement in a day for just 10,000. This is a fraction of the time and cost to build a house.Both the two companies will build homes in developing countries. They will build 100 in El Salvador next year. New Story’s co-founder said this was just a drop in the ocean. She said,“There are over 100 million people living in slum conditions, in what we call survival mode.”She added,“The tech is ready now to print very high-quality, safe homes in the places we’re building.”She also said 3D-printed houses could be built in richer countries.1.What is the news report mainly about?A) 3D printing for building becomes cheaper using new materials.B) 3D printing for building is made affordable for the first time.C) Two companies announce their new 3D printing technologies.D) Two companies start their businesses of building homes using 3D printing.2.What do we learn about the 3D-printed house of ICON company?A) It costs about 10,000 dollars a day.B) It takes one week to make a house.C) It costs less money than regular houses.D) It takes long time to make the first floor.3.What do we learn about New Story company?A) It is going to build houses in developing countries.B) It is requested to make houses for 100 million people.C) It is requested to make better houses for rich countries.D) It studies the possibility of making houses in the ocean.

题目解答

答案

1、答案：D2、答案：C3、答案：A

解析

整体考察内容

本文是一篇关于两家公司（ICON和New Story）使用3D打印打印技术建造经济适用房的新闻报道，题目主要考察对文章细节和主旨的理解。

题目1解析解析（主旨题）

问题：新闻报道主要讲什么？
解题思路：需概括全文核心内容。文章开头明确提到“Two companies... announced... they will start building affordable homes using 3D printing”（两家公司宣布将开始用3D打印建造经济适用房），随后具体介绍两家公司的计划（如ICON的建房速度和成本、New Story在萨尔瓦多的建房计划等）。
选项分析：

  • A：“3D打印建房因新材料更便宜”——文中未提“新材料”，仅说成本是传统的一小部分，非主旨；
  • B：“3D打印建房首次变得经济实惠”——“首次”未提及，文中强调“开始建造”而非“首次实惠”；
  • C：“两家公司宣布新的3D打印技术”——文中是“用3D打印建房的建房业务”，非“新技术”本身；
  • D：“两家公司开始用3D打印建造房屋的业务”——完全符合开头主旨（开头明确“start building”，全文围绕此展开）。

题目2解析（细节题）

问题：关于ICON公司的3D打印房屋我们了解到什么？
解题思路：定位到文中“Tech company ICON can make a one-floor house out of cement in a day for just $10,000. This is a fraction of the time and cost to build a house”（ICON公司一天用水泥造一层房屋，仅需1万美元，这是普通建房时间和成本的一小部分。选项分析：

  • A：“一天花费约1万美元”——原文是“一栋房屋1万美元”，非“每天1万美元”，偷换概念；
    租赁炒股配资
  • B：“造一栋房需一周”——原文是“一天”，错误；
  • C：“比普通房屋成本低”——“a fraction of the cost”（成本的一小部分）即成本更低，正确；
  • D：“造第一层需要很长时间”——原文是“一天”，错误。

题目3解析（细节题）

问题：关于New Story公司我们了解到什么？
解题思路：定位到文中“Both the two companies will build homes in developing countries. They will build 100 in El Salvador next year”（两家公司都将在发展中国家建房，明年在萨尔瓦多建100栋）。选项分析：

  • A：“将在发展中国家建房”——完全符合原文“build homes in developing countries”，正确；
  • B：“被要求为1亿人建房”——原文是“100 million people living in slums”（1亿人住贫民窟），未说“被要求为他们建房，错误；
  • C：“要求为富裕国家建更好的房”——原文New Story说“could be built in richer countries”（可能在富裕国家建），非“被要求”，错误；
  • D：“研究在海洋建房的可能性”——“drop in the ocean”是比喻“沧海一粟”，非字面“海洋建房”，错误。
