The name sounds funny but the idea is no joke: it’s a personal toilet called the pee-pool, Anders Wilhelmson, a Swedish architect, is the inventor of the pee-pool.
He became interested in the idea of sanitation(衛(wèi)生設(shè)施) after taking part in a research project on the social and political development of cities, One of the most common problems he found in developing countries was the lack of toilets, He wanted to do something to help, So working with others, he started the project in 2005, and the next year started a company called Peepoolple.
The toilet is a single—use bag made of environmentally friendly plastics, The inside is treated with urea （尿素）, a chemical commonly used as fertilizer, The hotter the weather, the more quickly the waste turns into what is needed by plants The sanitation process can be as soon as a couple of hours or as long as two to four weeks ,You can just bury it in a pot and grow whatever you like.
The company expects to start selling the bags in August in Kenya and Bangladesh, But it is just beginning production and sales in Nairobi now , Full production could reach about half a million bags a day and people may be able to buy the pee-pool in countries Vietnam, Bangladesh, etc.
The United Nations says more than two and a half billion people around the world do not have good sanitation ,Many have no choice but to use the outdoors, which is not only bad for the environment ,but also harmful to people’s health, Each year, poor sanitation leads to three fifths of those people getting an infectious disease which on average causes one out of 1,000 patients to die.
Jack Smith ,the founder of the World Toilet Organization ,says “This is quite an unacceptable situation given the fact that we are living in the modem world , And strangely, many of them own televisions ,phones but have no toilet.”

In the near future, we may be using our eyes to operate our smart-phones and tablets, even when it comes to playing popular games like Fruit Ninja.
The Gaze Group has been developing eye-controlled computer technology for nearly 20 years. But those devices have been firstly designed to help those with disabilities, and are very expensive.
“After a while, we figured out that probably the best way is to go for a mass-market way,” says Gaze’s Sune Alstrup Johansen. “where everybody would have this available."
Johansen and some of his colleagues have formed a new company, the Eye Tribe, which is hoping to develop the technology on a mass commercial level.
The technology works with the help of the computing device toward the user’s face. After making sure of the user’s eye movements, the technology is then able to easily find where a person’s eyes are moving, and then allow the eyes to control a cursor(光標(biāo)).
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at, ” reads an explanation on the Eye Tribe site.
There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world. Recently Xbox released the Kinect device, which lets users control their Xbox and play certain games using only their hands, legs and voices. But still, most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device. Johansen said a replaceable filter(濾光器)would be a cheap, convenient way for most consumers.
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

How would you like to sleep with one half your brain asleep and the other half awake? Dolphins sleep this way. Recently, scientists at Indiana State University have discovered that ducks sleep this way too. They found that ducks sleep half awake so they can rest and watch for danger at the same time.
After putting their ducks in a row and videotaping them, some researchers found ducks on the end of each row spent more time asleep with one eye open, apparently looking for predators.
“The more the ducks felt threatened, the more they slept with one eye open,” said lead author Niels C. Rattenborg, a graduate student at Indiana State University, Terre Haute. “The unique aspect is not that they do it, but that they control it. When they sleep at the edge of a group, they tend to realize greater danger, so they spend more time sleeping with one half of their brain.” Ducks with one eye open were still awake enough to detect predators, said the authors of the study, which appears today in the journal Nature.
The researchers studied four groups of four ducks held in plastic boxes, which were arranged in a row. Ducks on the end were found to sleep with one eye open 31.8 per cent of the time, compared to 12.4 percent of the time for ducks in the central position.
Also, ducks in the central position did not open one eye more than the others, while ducks on each end kept the eye facing away from the group open 86.2 per cent of the time. Brain wave readings of the ducks showed that the half of the brain receiving signals from the closed eye indicated that half of the brain was sleeping. Signals from the half of the brain receiving signals from the open eye showed a state between fully awake and asleep.
小題1:The under lined word “predator” is most likely to mean      .
A．a(chǎn)n animal that is likely to be friends with ducks
B．a(chǎn) human being who looks after and feeds ducks
C．a(chǎn) scientist who does research work on animals
D．a(chǎn)n animal that hunts, kills and eats other animals
小題2:Ducks at the end of each row sleep with one eye open because      .
A．they are looking for food
B．they are watching out for danger
C．they want to enjoy the scenery
D．they are unique in their sleeping habit
小題3:Which of the following is true according to the passage?
A．Ducks with one eye open at the edge can still enjoy a certain degree of sleep.
B．Ducks with less sense of duty usually choose to stay in the center of a row.
C．Ducks on the northern end of a row would keep their eye facing the south open.
D．A video tape recorder was the only electronic device used in the experiment.

Downing the last drop of an expensive famous brand H2O as well as remembering to throw the empty bottle in the recycling bin, makes you feel pretty good about yourself, right? It shouldn’t. Even when the bottles are recycled, there are all kinds of other consequences of swallowing bottled water, says Melissa Peffers, the air-quality program manager for Environmental Defense.
The containers are often filled in faraway lands, then shipped from abroad, and stored in refrigerators at your local store. Compare that with the influence on environment of turning on your tap, filling a glass, and drinking up!
Anyone who is choosing bottled water for health reasons is misguided, says Peffers, “Most bottled water is just tap water.” And what comes out of your tap is carefully monitored to follow the strict rules. Consider another fact that bottled water is surprisingly expensive, especially when compared with the alternative, which is almost free, and it is astonishing that America’s desire for bottled water seems impossible to satisfy, reaching nearly 30 billion bottles a year.
“My parents’ generation never had bottled water,” says Isabelle Silverman, an Environmental Defense legal adviser. She has made a commitment to going bottle free. “You don’t need to fetch it home from the store, and it’s cheaper,” she adds.
Bottled water’s role as a status symbol needs to change, Peffers points out. So when a waiter at an expensive restaurant offers  “And what’s your drink?” that’s no reason to forget your conviction(信念). “Don’t be afraid to say, ‘I’ll have tap.’ Say it loud enough that the other tables nearby can hear you,” Peffers says. “And then spend that money on a dessert.”
小題1:In the first paragraph, the underlined sentence “It shouldn’t.” suggest that people _______.
A．shouldn’t feel pleased with finishing the water in the bottle.
B．shouldn’t feel good about drinking an expensive brand H2O.
C．shouldn’t be pleased with just recycling empty bottles.
D．shouldn’t be satisfied with drinking only bottled water.
小題2:According to the author, tap water is _______.
A．a(chǎn)s safe as bottled waterB．morel likely to be polluted
C．healthier than bottle waterD．less convenient than bottled water
小題3:The underlined part “going bottle free” (in Para. 4) means “_______”.
A．making bottled water freeB．giving up bottled water
C．recycling use water bottlesD．providing free water containers
小題4:Why does Peffers ask people to say “I’ll have tap.” Loudly?
A．To encourage them to set an example for others to follow.
B．To advise them to save the money for one more dessert.
C．To remind them to be aware of their social status.
D．To persuade them to speak confidently in public.

Many of us believe that a person’s mind becomes less active as he grows older. But this is not true, according to Dr Jarvik, professor of psychiatry at the University of California. She has studied the mental functioning of aging persons for several years. For example, one of her studies concerns 136 pairs of twins (雙胞胎), who were first examined when they were already 60 years old. As Dr Jarvik continued the study of the twins into their 70s and 80s, their minds did not generally decline (衰弱) as was expected.
　　However, there was some decline in their psycho-motor speed. This means that it took them longer to finish mental tasks than it used to. But when speed was not a factor, they lost very little intellectual (智力的) ability over the years. In general, Dr Jarvik’s studies have shown that there is no decline in knowledge or reasoning ability. This is true not only with those in their 30s and 40s, but with those in their 60s and 70s as well.
　　It is true that older people themselves often complain that their memory is not as good as it once was. However, much of what we call “l(fā)oss of memory” is not that at all. There usually was incomplete learning in the first place. For example, the older person perhaps had trouble hearing, or poor vision, or was trying to learn the new thing at too fast a speed. In the cases where the older person’s mind really seems to get worse, it is not necessarily a sign of decline due to old age. Often it is simply a sign of a sad emotional state. 
小題1: This passage is mainly about _______.
A．what caused mental decline
B．a(chǎn) new discovery about mental decline
C．the difference between middle-aged and older persons
D．how Dr Jarvik studied mental functioning of the twins
小題2:The word “psychiatry” in paragraph 1 most probably means _______.
A．the study of diseases of the mind
B．the study of physical diseases
C．the study of twins’ growth
D．the study of human behavior
小題3:More often than not, what we call mental decline is actually a sign of _______.
A．a(chǎn) worsening state of healthB．old age
C．nervous tensionD．a(chǎn) state of unhappiness

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.
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.
小題1: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
小題2: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
小題3:When the program was over, the students  ________.
A．entered that collegeB．wrote research reports
C．paid for their researchD．found way to make money
小題4:The underlined expression “on the cutting edge” in paragraph 5 means “on the most  ___ position”.
A．importantB．favorable
C．a(chǎn)stonishingD．a(chǎn)dvanced

Scientists say they now have proof to support the old-fashioned advice that it's best to sleep on a problem. They say sleep strengthens the memory and helps the brain organize the masses of information we receive each day.
Lead researcher Bob Stickgold at the Harvard Medical School said, "Sleep helps us draw rules from our experiences. It's like knowing the difference between dogs and cats even if it's hard to explain."
The US research team studied how well students remembered connections between words and symbols (象征) , reports New Scientist. They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept. They found that people were better able to remember lists of related words after a night's sleep than after the same time spent awake during the day. They also found it easier to remember themes (主題) that the words had in common. But they forgot around one in four more themes if they had been awake. Prof. John Groeger, of Surrey University's Sleep Research Centre, said, "People have been trying for years to find out what the purpose of sleep is, as we know that only certain parts of it have a restorative (有助恢復(fù)的) value. " "We form and store huge numbers of experiences in the head every day, and sleep seems to be the way the brain deals with it all."
小題1:The phrase" to sleep on a problem" in Paragraph 1 most likely means to______.
A．pay full attention to a problemB．wait until later for a decision
C．sleep to forget a problemD．have difficulty sleeping
小題2:In the study by the US research team, students were asked to______.
A．put together words of similar meanings
B．remember words and their meanings
C．show their knowledge of words
D．make up lists of related words
小題3:Which of the following may be easier to remember?
A．Themes learned right before the test
B．Rules from personal experience
C．Words learnt before a good sleep
D．Ideas stored together in the brain
小題4:What may be the importance of the research?
A．It shows sleep may help us manage information
B．It helps find out the common themes of word
C．It tells us that more sleep can improve health
D．It proves the value of old-fashioned advice

Scientists are developing a new kind of machine to take the place of humans. These machines can do jobs in places that are too dangerous for humans. For example, they are being developed to work in nuclear power center, deep under the oceans and in outer space.
John Marrit, a psychologist(心理學(xué)家) in Williamsburg Massachusetts, helped develop the new machine. This is how they work. A machine is placed in an area far away from the person who operates it. The person wears special hard hat with television screens and sound equipment. The screens and sound equipment let the person see and hear exactly what the machine is seeing and hearing. Mr. Marrit says this gives the person the feeling of being in the same place as the machine. The idea, he says, is being there without going there. The person uses an electronic control to make the machine move. The machine copies the person’s movements exactly. If the person raises his right arm, the machine raises the right arm, too. This means an expert can do a dangerous job while staying in the safe place. For example, a person can direct the machine to destroy a bomb without going near the bomb himself.
小題1:The new kind of machine being introduced in the passage is _______.
A．in existenceB．only an idea
C．being tried outD．being researched and developed
小題2:The machine _______.
A．follows the person’s order
B．is controlled by a computer
C．does exactly what the person does
D．is controlled by a television on the person’s head
小題3:The difference between such a new machine and a robot is that _______.
A．the new machine is more difficult to make than a robot
B．the new machine is more difficult to be controlled
C．a(chǎn) robot is controlled by man indirectly
D．a(chǎn) robot can’t be used in places too dangerous or faraway
