C

A gadget which makes water out of air could become the greatest househo1d invention since the microwave.

Using the same technology as a dehumidifier(除濕器),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(過(guò)濾器)and over a cooling instrument which changes it into water droplets.It can produce up to 1 2 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.

63.What does the underlined word “it” refer do?

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

       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.

65.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.

66.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

My dentist had just pulled out one of my tooth and had told me to rest for

while. My mouth was full with cotton wool. He knew I collected bird eggs and asks

me whether my collection was growing. He then asked me a lot of other question.

In answer to these questions, I could neither nod or make strange noises.

Meanwhile, my tongue was busy search out the hole where the tooth had been. I

suddenly felt very worried, so couldn’t say everything. When the dentist at last

removed the cotton wool, I was able to tell him of that he had pulled out the wrong

tooth.
