A gadget (器具) which makes water out of air could become the greatest household invention since the microwave.

Using the same technology as a dehumidifier (除湿器), 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 (过滤器) and over a cooling instrument which changes it into water drops. 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 (粗略地) 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.

49. What does the underlined word “it” refer to?

A. Drinking water. B. Invention. C. Microwave. D. Water Mill.

50. What do we learn about the machine?

A. It works in the same way as microwaves.

B. It is very expensive for families to afford.

C. It absorbs steam and turns it into water.

D. It helps to make the water clean to drink.

51. What does the passage lead us to believe?

A. The cost of water will go up. B. Bottled water will disappear sooner.

C. The machine is energy saving. D. The machine will be popular worldwide.

52. What’s the best title for the passage?

A. A New Way to Solve Water Problem. B. A Machine to Make Water out of Air.

C. A Dehumidifier to Produce Water. D. An Absolutely New Invention
