Ⅰ. 閱讀理解

• 1．There are robot cleaners and robot mops to help us around the house，so why not a robot to build our houses？Wait no longer.Now there is a set of electronics to do just that，build a house from scratch，and fast.
     Forget weeks to find a builder and months for house construction；a machine developed in the United States can build a 232 sqm house layer by layer in a single day.University of Southern California's Professor Behrokh Khoshnevis has designed the giant robot that replaces construction workers with a mouth on an arm of crane，which spits out concrete and can quickly build a house according to a computer pattern.The technology，known as Contour（輪廓）Crafting，could revolutionise the construction industry.
     Contour Crafting could greatly decrease the cost of homeowning，making it possible for millions of displaced people to get on the property ladder.It could even be used in disaster relief areas to build emergency and replacement housing.As Prof.Khoshnevis points out，if we look around almost everything is made automatically these days - shoes，clothes，home appliances，cars.The only thing that is still built by hand are buildings.
     The Contour Crafting system is a robot that automates age-old tools normally used by hand.These are applied by a robotic crane that builds a three-dimensional object.The nature of the technology means it will also be possible to create curved walls and architecture that is both "exotic（異國(guó)情調(diào)的）and beautiful" according to Prof.Khoshnevis.As a result，it could be ideal to print out expensive houses according to customers' demands.
     Furthermore，Prof.Khoshnevis believes that the technology could be applied beyond our planet."Contour Crafting technology has the potential to build safe，reliable，and affordable structures，habitats，laboratories，and other facilities on the moon and Mars before the arrival of human beings，" his website reads.
     According to the International Labour Organisation，construction employs nearly 110 million people worldwide and "plays a major role in fighting the high levels of unemployment and in absorbing extra labour from the rural areas".What the implications are for builders is，of course，a major concern.But Khoshnevis says "the reality is that a lot of new jobs can be created in this field as well".Instead of building the house，workmen are used to maintain the machine.
