1A US company, Mighty Buildings, can 3D-print a house and stick it in your backyard 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 3Dprinted sheds cost 45 per cent less to build.The firm apparently takes just 24 hours to construct 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 typical build.

4It's not the first company to offer 3D-printed buildings: An entire street of the hightech 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（自動化的）, according to the company. The rest, including the windows, plumbing and electrics,is done separately on site.

6According 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（多個的）other orders.

73D 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 cheaply build houses. Sadly the tech is far from mainstream for now. A recent report suggested 3D-printed houses built in less than 24 hours will form a key part of the UK's housing market by 2025.

語篇研讀

本文是一篇科技成果介紹類說明文，其主題語境為“人與社會”范疇中的“技術(shù)創(chuàng)新”。文章介紹了一家美國公司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打印機可以快速、廉價地建造房屋，但目前該技術(shù)還遠(yuǎn)未成為主流。不過，到2025年，在24小時內(nèi)建造的3D打印房屋將成為英國住房市場的重要組成部分。全文結(jié)構(gòu)如下：

Ⅱ.語句分析

All you need to do is sit back and relax as we deliver and install your unit for you. 您需要做的就是在我們?yōu)槟桓逗桶惭b您的房屋時，坐下來休息。

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