A gadget 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 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 liter of water costs around 20 pence 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.
68.What does the underlined word “it” refer to?
A.Drinking water.  B.Invention.    C.Microwave.      D.Water Mill.
69.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 wet air and turns it into water.
D.It helps to make the water clean to drink.
70.What does the passage lead us to believe?
A.The cost of water will go up.  B.Bottled water will disappear soon.
C.The machine is energy saving. D.The machine will be popular worldwide.
71.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

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes(酶)that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic (酸性的). To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat . Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism(新陈代谢) becomes inactive, and then result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的) circle in its tracks, people need to consume food and supplements that will neutralize (使…中和)the acid already accumulated in body. Eating the right types of raw and whole foods can help. it’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself , you need to take an active approach..

Looking back on my childhood, I am convinced that naturalists are born and not made. Although we were brought up in the same way, my brothers and sisters soon abandoned their pressed flowers and insects. Unlike them, I had no ear for music and languages. I was not an early reader and I could not do mental math.
Before World War I we spent out summer holidays in Hungary. I have only the dim(模糊的)memory of the house we lived in, of my room and my toys, Nor do I recall clearly the large family of grandparents, aunts, uncles and cousins who gathered next door. But I do have a crystal clear memory of dogs, the farm animals, the local birds and above all, the insects.
I am a naturalist, not a scientist. I have a strong love of the natural world, and my enthusiasm has led me into various investigations. I love discussing my favorite topics and enjoy burning the midnight oil reading about other people’s observations and discoveries.Then something happens that brings these observations together in my conscious mind. Suddenly you fancy you see the answer to the riddle. Because it all seems to fit together. This has resulted in my publishing 300 papers and books, which some may light honor, with the title of scientific research.
But curiosity, a keen eye ,a good memory and enjoyment of the animal and plant world do not make a scientist: one of the outstanding and essential qualities required is self-discipline, a quality I lack, A scientist can be made a naturalist. If you can combine the two, you get the best of both worlds.

Linda Evans was my best friend-like the sister I never had, We did everything together:piano lessons, movies, swimming , horseback riding.
When I was 13, my family moved away, Linda and I kept in touch through letters, and we saw each other on special times- like my wedding and Linda’s. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back, stamped “Address Unknown”. I had no idea about how to find Linda.
Over the years, I missed Linda very much, I wanted to share happiness of my children and then grandchildren, And I needed to share my sadness when my brother and then mother died, There was an empty place in my heart that only a friend like Linda could fill.
One day, I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman—Linda’s married name. “There must be thousands of Wagmans . ”I thought, but I still wrote to her.
She called as soon as she got my letter, “Mrs, Tobin!” she said excitedly, “Linda Evans Wagman is my mother.”Minutes later I heard a voice that I recognized at once, even after 40 years. We laughed and cried and caught up on each other’s lives, Now the empty place in my heart is filled, And there’s one thing that Linda and I know for sure: we won’t lose each other again!

New technology links the world as never before. Our planet has shrunk. It’s now a “global village” where countries are only seconds away by fax or phone or satellite link. And, of course, our ability to benefit from this high-tech communications equipment is greatly increased by foreign language skills.
Deeply involved with this new technology is a kind of modern businesspeople who have a growing respect for the economic value of doing business abroad. In modern markets, success overseas often helps support domestic business efforts.
Overseas assignments (指派) are becoming increasingly important to advancement within executive (行政) ranks. The executive stationed in another country no longer need fear being “out of sight and out of mind.” He or she can be sure that the overseas effort is central to the company’s plan for success, and that promotions often follow or accompany an assignment abroad. If an employee can succeed in a difficult assignment overseas, superiors will have greater confidence in his or her ability to manage back in the United States where cross-cultural considerations and foreign language issues are becoming more and more common.
Thanks to a variety of relatively inexpensive communications devices (装置) with business applications, even small businesses in the United States are able to get into international markets.
English is still the international language of business. But there is an ever-growing need for people who can speak another language. A second language isn’t generally required to get a job in business, but having language skills gives a candidate the edge when other qualifications appear to be equal.
The employee posted abroad who speaks the country’s language has an opportunity to fast-forward certain negotiations, and can have the cultural insight (洞察力) to know when it is better to move more slowly. The employee at the home office who can communicate well with foreign customers over the telephone or by fax machine is an obvious asset (有价值的人或物) to the firm.
With the increased use of high-tech communications equipment, businesspeople ________.

A.are eager to work overseas
B.have to get familiar with modern technology
C.are gaining more economic benefits from domestic operations
D.are attaching more importance to their overseas business

B.better control the whole negotiation process
C.easily make friends with businesspeople abroad
