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.

Instead of hitting the beach, fourteen high school students traded swimming suits for lab coats last summer and turned their attention to scientific experiments.
The High School Research Program offers high school students guidance with researchers in Texas A&M’s College of Agriculture and Life Sciences. Jennifer Funkhouser, academic adviser for the Department of Rangeland Ecology and Management, directs this four-week summer program designed to increase understanding of research and its career potential(潜能)。
Several considerations go into selecting students, including grades, school involvement and interest in science and agriculture. And many students come from poorer school districts, Funkhouser says, “This is their chance to learn techniques and do experiments they never would have a chance to do in high school.”
Warner Ervin of Houston is interested in animal science and learned how to tell male from female mosquitoes(蚊子).His adviser, Craig Coates, studies the genes of mosquitoes that allow them to fight against malaria and yellow fever. Coates thought this experience would be fun and helpful to the high school students.
The agricultural research at A&M differs from stereotypes. It’s “molecular(分子)science on the cutting edge,” Funkhouser says. The program broadened students’ knowledge. Victor Garcia of Rio Grande City hopes to become a biology teacher and says he learned a lot about chemistry from the program.
At the end of the program, the students presented papers on their research. They’re also paid $600 for their work----another way this program differs from others, which often charge a fee.
Fourteen students got paid to learn that science is fun, that agriculture is a lot more than milking and plowing and that research can open many doors.
63.The research program is chiefly designed for .
A. high school advisers from Houston
B. college students majoring in agriculture
C. high school students from different places
D. researchers at the College of Agriculture and Life Sciences
64.It can be inferred from the text that the students in poorer areas .
A. had little chance to go to college
B. could often take part in the program
C. found the program useful to their future
D. showed much interest in their high school experiments
65.When the program was over, the students .
A. entered that college B. wrote research reports
C. paid for their research D. found way to make money
66.The underlined expression “on the cutting edge” in paragraph 5 means “on the most________
position”.
A. important B. favourable C. astonishing D. advanced
67.What would be the best title for the text?
A.A Program for Agricultural Science Students
B. A Program for Animal Science Students
C. A Program for Medical Science Lovers
D. A Program for Future Science Lovers

When a Swedish ship that sank in 1628 was recovered from the port of Stockholm, historians and scientists were overjoyed with the chance to examine the remains of the past. The ship construction showed how ships were built and operated during the seventeenth century. In this way, artifacts, objects made by human beings, provided a picture of daily life almost 400 years ago.
Underwater archaeology –the study of ships, aircraft and human settlements that have sunk under large bodies of water—is really a product of the last 50 years. The rapid growth of this new area of study has occurred because of the invention of better diving equipment. Besides the Swedish ship
wreck(残骸), underwater archaeologists have made more exciting discoveries such as the 5,000-year-old boats in the Mediterranean Sea.
Underwater archaeology can provide facts about the past. In ancient ports all over the world are ships sunken in the past 6,000 years. There are also sunken settlements in seas and lakes telling of people’s way of life and their systems of trade in ancient times. Underwater archaeologists want to study these objects to add to the world’s knowledge of history , but they have to fight two enemies. One enemy is treasure hunters who dive for ancient artifacts that they can sell to collectors. Once sold, these objects are lost to experts. The second enemy is dredging machines (挖掘机)often used to repair ports. These machines destroy wrecks and artifacts or bury them deeper under sand and mud. By teaching the public about the importance of underwater “museums” of the past, archaeologists are hoping to get support for laws to protect underwater treasures.
59．What purpose does Paragraph 1 serve in the passage?
A．To provide background information of the topic.
B．To attract readers’ attention to the topic.
C．To use an example to support the topic.
D．To offer basic knowledge of the topic.
60．The aim of underwater archaeology is to___________.
A．exploit water bodies
B．search for underwater life
C．study underwater artifacts
D．examine underwater environment
61．Underwater archaeologists are worried because___________.
A．sea hunters have better diving equipment
B．their knowledge of world history is limited
C．dredging machines cause damage to the ports
D．sold artifacts can hardly be regained for research
62．What is the main purpose of the passage?
A．to introduce a young branch of learning.
B．To discuss the scientists ’ problems.
C．To explain people’s way of life in the past.
D．To describe the sunken ships.

Americans can travel almost anywhere they choose. But to protect its people, the government lists a few dangerous places where Americans cannot go. These places are unfriendly countries or countries at war. There, the traveller might not be safe. These countries are listed in a small book called a passport（护照）.
This passport is a government request for the safety of its travelling people. It is also a government’s pledge（保证） that the people will obey the rules of the host country（东道国）.
To receive a passport from the government, a traveller must prove that he is an American citizen （公民）. An American can not go overseas（外国） without a passport. Only certain close countries such as Canada and Mexico do not ask for passports.
Pasted （粘贴）inside the passport is the traveller’s picture. Children travelling with their parents are included in one parent’s book.
Thousands of people from the United States visit other countries every year. An American traveller might carry plane tickets, money, clothing and many other things. But the most important that he carries in another country is his passport.

The clock struck eleven at night. The whole house was quiet. Everyone was in bed except me. Under the strong light, I looked sadly before me at a huge pile of that troublesome stuff(东西) they call “books”.

myself. I didn’t answer, In fact I dared not.
