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.

Ottawa is the capital of Canada. It is the second largest city in Ontario and the fourth largest city in the country.
The Centre Block is the main building on Parliament Hill (国会山). It is also the location of several ceremonial spaces, such as the Hall of Honor and the Memorial Chamber. The present Centre Block is the second iteration of the building, after the first was destroyed by fire in 1916, and it is one of the most recognizable buildings in Canada.
Downtown Ottawa is the commercial and economic centre of the city. Most of the buildings are office towers. While most of Ottawa’s high tech industry is based elsewhere, it has a significant presence in the downtown core (中心部分). The downtown also contains a number of apartments, hotels, and the older single family homes and townhouses along its edges.
The National Gallery of Canada is one of Canada’s premier (首位的) art galleries. The Gallery has a large and varied collection of paintings, drawings, sculpture and photographs. Although its focus is on Canadian art, it also holds works by some noted American and European artists.
The Rideau Canal is the oldest continuously operated canal system in North America. At the very beginning, the purpose of the Rideau Canal was military, as it was intended to provide a secure supply and communication route between Montreal and the British naval (海军的) base in Kingston.

Across the United States, universities and colleges have been looking to become more sustainable (可持续发展的) and more than 600 schools have already planned to become eco-friendly. The EcoDorm, home to 36 students at Warren Wilson College in Swannanoa, was designed to be sustainable from top to bottom, or in this case, from its rainwater-collection system to its garden. The dormitory is bringing new meaning to the concept of living “green” at college.
At Warren Wilson College, a biological science school with fewer than 1,000 students, the sustainability drive came from the student body. The EcoDorm concept was presented ten years ago by two students; a planning committee firstly suggested using building materials like corncob. Although the architects disagreed with the idea, they came up with other creative solutions: Wood siding was taken from the trees grown in the school yard that were suffering from a disease, and rainwater was collected in an old railway car and pumped back into the house to clean the toilets.
All in all, the dorm uses nearly two-thirds less electricity than a similar-sized traditional building world. But even the most sustainable homes need continued efforts from its livers. And in the case of EcoDorm, students live by their words. Most also take advantage of the dorm’s bio-garden, planting and harvesting fruits and vegetables. “I didn’t have to worry about paper towels being wasted or feel bad about drying my clothes outside,” Jeremy Lekich, the dorm’s gardener, said. “Basically, it has made my life easier.”We can learn from the text that the EcoDorm in the US .
| A．offers students the chances to have a natural living at college |
| B．was firstly built by two college students |

In Eastern Europe, blue jeans symbolize (象征) American culture and “the good life”. In Spain they are known as “cowboys”. In China, jeans are known as “niuzaiku”, also, “cowboy trousers”, which means they are connected with the American West cowboy culture and outdoor work.
Jeans are usually made from denim (粗布), but may also be made from other materials. The earliest known cloth for jeans was a thick cotton cloth from the Indians. At first they were working clothes. They became popular among teenagers in the 1950s. Today jeans are a very popular form of casual wear around the world and come in many styles and colors.
Jeans were first made in Genoa in Italy. The trousers were made for the Genoese navy (海军) because they needed trousers which could be worn wet or dry, and whose legs could be easily rolled up while the men were cleaning the ships. These jeans would be washed by pulling them in large fishing nets behind the ship, and the sea water would make them white.
In the 1850s Levi Strauss, a business man living in San Francisco, was selling blue jeans under the “Levi’s” name to the coal workers of California.
During World War II, the coal workers liked jeans very much because they were strong and did not tear easily. In the 1950s, jeans became popular with young people in the United States. Wearing of blue jeans by teenagers was the symbol of rebels (反叛者) in TV programmes and movies. Some cinemas and restaurants refused to let people in if they wore blue jeans. In the 1980s, jeans finally became high fashion clothing, when famous designers started making their own styles of jeans, with their own labels on them. Sales of jeans went up and up.From the first paragraph we know that ________.
| A．cowboys wear jeans only |
| B．cowboys live a good life |
| C．American culture is cowboy culture |
| D．cowboy culture is usually related to the West of America |
Jeans were first made in ______.
| A．Italy | B．America | C．Spain | D．China |

| A．the name of a worker |
| B．the brand (名牌) of a kind of jeans |
| C．the name of a kind of cloth |
| D．the nickname of a businessman |

| A．Because jeans were made for workers. |
| B．Because jeans were made of denim. |
| C．Because it was during the time of war. |
| D．Because wearing jeans was the symbol of rebels. |
I went over my grandmother’s house today and she didn’t have time for me. You see, the lady’s husband downstairs died and my Grandmother wanted to make some cookies for her. My grandmother did not analyze (分析) how the lady treated her, or if the lady needed any cookies, or even if the lady would like the cookies. She didn’t think how much the lady has done for her. She simply began baking.
My Grandmother turned 94 last week and this I believe is her secret to life. My grandmother is generous and hard-working in a way that is rare for our time. She lives by a simple belief: if someone needs your help, you help. Never mind all the analyzing and thinking whether the person deserves or appreciates the help. My grandmother doesn’t sit around thinking about who might be making use of her: she simply does what is needed.
At 94, she is busy in life. She is making a blanket for a new great grandchild, and worried that I don’t have enough kitchen towels for my home. She is bringing soup to a sick neighbor, and teaching the new wife of her cousin (who is 88) how to cook Italian food.
My grandmother had every right to give up, but she didn’t — and amazingly life did bring her good things, like a husband with twinkling blue eyes who was much ahead of his time and believed that men should do an equal amount of cooking and cleaning in the home, three beautiful children (my father and two aunts), 22 grandchildren, and five great grandchildren. My grandmother is not afraid to give someone she barely knows a bowl of soup. She never keeps herself out of the world.The reason why my grandmother made cookies for the lady downstairs is that ________.
| A．she thought the lady was too busy |
| B．she would make them as thanks to her |
