A gadget which makes water out of air could become the greatest household invention since the microwave.Using the same technology as a dehumidifier，the Water Mill is able to create a ready supply of drinking water because it can always get it from an unlimited source—the air.
The company behind the machine says not only does it offer an alternative to bottled water in developed countries，but it is a solution for the millions who face a daily water shortage.
The machine works by drawing in wet air through a filter and over a cooling instrument which changes it into water droplets.It can produce up to 12 liters a day.The Water Mill will also produce more water when storms pass over，as the amount of water which is contained in the air increases.In keeping with its eco-development，the machine uses the same amount of electricity as three lights.
Inventor Jonathan Ritchey said：“The demand for water is off the chart.So people
are looking for freedom from water distribution systems that are shaky and unreliable.”
The machine，which is about 3 feet wide，is likely to cost ￡800 when it goes on sale here in the spring.Its maker，Canadian Firm Element Four，roughly calculates that a litre of water cost around 20p to produce.
Environmentalists state that half the world's population will face water shortage because of climate change by 2080.One in five is said to lack access to safe drinking.
The Water Mill is not effective in areas where the amount of water contained in the air is below about 30 percent，but in Britain that won't be much of a problem.

TOKYO（Reuters）—Bend it，write on it，read it—just don't try to fold it into a paper plane.Electronic paper is Japan's answer to rising raw material cost，limited resources and booming demand for printed matter from markets such as China and India.
At a high-tech fair in Tokyo this week，Japanese firms showed the latest versions of various products，ranging from thick readers to thin displays that look like
plastic sheets and can be bent.
E-Ink，which produces Sony's Reader tablet，says consumers will eventually embrace the energy-saving technology as the cost of paper and fuel goes up.
“The BRIC nations like India and China are consuming so much paper as their economies expand that the cost of A4-size paper is up by 20 to 30 percent，” said Ryosuke Kuwada，vice president for E-Ink corporation's Asia Pacific Region，referring to an abbreviation that groups Brazil，Russia，India and China.
“As people try to wean_themselves_off pulp paper，the push for electronic paper is going to strengthen，” he added.
Japan，known for its beautiful hand-made paper as well as its advanced technology，has already been trying to combine two.
Companies such as Fujitsu and Sony use electrophoretic displays，or EPD，for everything from watches and mobile phones to electronic readers.This display sends electronic charges along a grid existed in the e-paper which cause tiny black and white particles to move，creating text and images.
“This is going to be a new kind of personal tool that businessmen would carry in their bags.It will be yet another powerful tool after the cellphone，” said Yoshiaki Kageyama，director of Fujitsu's e-paper division.
Fujitsu recently developed flexible e-paper that can display different colors，a further step towards publishing e-magazines and newspapers.
5．Why does Japan invent e-paper?

c．Because the demand for printed matter is high. d．Because the cost of e-paper is low. A．a，b，c

C．a，c，d
D．b，c，d
6．The underlined phrase “wean themselves off” in Paragraph 5 probably means ______.
A．devote themselves to B．gradually stop using C．make full use of D．recycle effectively 7．What can we learn from the passage?
A．The production of e-paper will bring down the cost of paper. B．Japan's paper is mostly exported. C．India and China are in need of paper.
