1 A US company， Mighty Buildings， can 3D - print a house and stick it in your back- yard for just￡ 75， 000. Mighty Buildings uses a 20ft - high printer stored in a California warehouse to make you a small cottage （小屋） and ships it to your property on a truck.

2“All you need to do is sit back and relax as we deliver and install your unit for you ， ” Mighty Buildings says on its website.

3Compared to new houses of a similar size in California， Mighty Buildings says its 3D- printed sheds cost 45 per cent less to build. The firm apparently takes just 24 hours to con- struct a 350-square-foot house， using 95 per cent less labour than traditional methods. The technique is also said to be more eco-friendly， producing 90 per cent less waste than a typi- cal build.

4It，s not the first company to offer 3D-printed buildings： An entire street of the high - tech houses is being built in Mexico. However， Mighty Buildings， technology is different as it prints more elements of the house—the dwellings in Mexico， for instance， only feature 3D-printed walls and floors.

5As much as 80 per cent of Mighty Buildings， construction process is now automated （自動(dòng)化的） ， according to the company. The rest， including the windows， plumbing and electrics， is done separately on site.

6 According to the firm ，s website， prices start around $100， 000 （￡ 75， 000） for an environmentally friendly， studio - sized apartment. Mighty Buildings has already delivered two fully-functioning units in San Ramon and San Diego and is currently fulfilling multiple （多個(gè)的） other orders.

7 3D printing is a process of layering up a material to build complicated structures. It works just like regular house printers—but instead of ink， a 3D printer will use materials like plastic or metal. Using giant 3D printers， it ， s been proven possible to quickly and cheaplybuildhouses.Sadlythetechis far frommainstream fornow. Arecentreport suggested 3D-printed houses built in less than 24 hours will form a key part of the UK ，s housing market by 2025.

語(yǔ)篇研讀

本文是一篇科技成果介紹類說(shuō)明文，其主題語(yǔ)境為“人與社會(huì)”范疇中的“技術(shù)創(chuàng) 新”。文章介紹了一家美國(guó)公司 Mighty Buildings 以 3D 打印技術(shù)建造房屋的情況。文 章特別指出：盡管使用巨型 3D 打印機(jī)可以快速、廉價(jià)地建造房屋，但目前該技術(shù)還遠(yuǎn) 未成為主流。不過，到 2025 年，在 24 小時(shí)內(nèi)建造的 3D 打印房屋將成為英國(guó)住房市場(chǎng) 的重要組成部分。全文結(jié)構(gòu)如下：

【點(diǎn)石成金】本句是一個(gè)主從復(fù)合句。All is sit back and relax 是主句，其中 and 連接的 sit back 和 relax 是兩個(gè)并列的省略了to 的不定式（短語(yǔ)），在句中作表語(yǔ);you need to do 是省略了關(guān)系代詞 that 的限制性定語(yǔ)從句，修飾先行詞 all;as we deliver and install your unit for you 是 as引導(dǎo)的時(shí)間狀語(yǔ)從句。
