A scientist who developed a way to calculate how much water is used in the production of anything from a cup of coffee to a hamburger was awarded the 2008 Stockholm.Water Prize.
Professor John Anthony Allan of the University of London in Britain won the award for introducing the idea of “virtual water(虚拟水)”,a calculation method that has changed the nature of trade policy and research.
Allan has written seven books and published more than 100 papers.
The Stockholm International Water Institute said this idea is now embedded(埋藏)in the production of foods and industrial products.The institute said Allan's work had made a big effect on global trade policy and research, especially in water-scarce(缺水的)regions.
“The improved understanding of trade and water management issues on local,regional and global scales are of the highest value for the successful and sustainable(可持续的)use of water resources,”it said.
“People do not only use water when they drink it or take a shower,”the institute said.“Behind the morning cup of coffee,there are 140 liters of water that was used to grow,produce,package and ship the beans.”That is about as much water as a person in England uses on average for all daily drinking and household needs.
"For a single hamburger,about 2,400 liters of water are needed.In the USA,the average person uses nearly 7,000 liters of virtual water every day."It said that was more than three times the average use of a Chinese person.
1.Allan was awarded the prize because______.
A. he wrote seven books on trade policy
B. he published more than 100 papers on water management
C. lie found a new kind of water in water-scarce areas
D. he came up with the idea of virtual water

Our brains work in complex and strange ways.There are some people who can calculate the day of the week for any given date in 40,000 years,but who cannot add two plus two.Others can perform complex classical piano pieces after hearing them once,but they cannot read or write.
Dr.J.Langdon Down first described this condition in 1887.He called these people idiot savants.An idiot savant is a person who has significant mental impairment(损伤),such as in autism(孤独症,自闭症)or retardation.At the same time,the person also exhibits some extraordinary skills,which are unusual for most people.The skills of the savant may vary from being exceptionally gifted in music or in mathematics,or having a photographic memory.
One of the first descriptions of a human who could calculate quickly was written in 1789 by Dr.Benjamin Rush, an American doctor.His patient,Thomas Fuller,was brought to Virginia as a slave in 1724.It took Thomas only 90 seconds to work out that a man who has lived 70 years,17 days,and 12 hours has lived 2,210,500,800 seconds. Despite this ability,he died in 1790 without ever learning to read or write.
Another idiot savant slave became famous as a pianist in the 1860s.Blind Tom had a vocabulary of only 100 words,but he played 5,000 musical pieces beautifully.
In the excellent movie Rain Man,made in 1988 and available on video cassette,Dustin Hoffman plays an idiot savant who amazes his brother played by Tom Cruise,with his ability to perform complex calculations very rapidly.
Today we more clearly recognize that the idiot savant is special because of brain impairment.Yet not all brain impairment leads to savant skills.Some studies have shown that people who have purposeful interruption of the left side of the brain can develop idiot savant skills.However few people wish to participate in such experiments.There are many excellent reasons for not undergoing unnecessary experimentation on one's brain.The term idiot savant is outdated and inappropriate.Virtually all savants have a high degree of intelligence and are thus not idiots.
1.What does the passage mainly talk about?
A. Idiot savants have areas of outstanding abilities.
B. Human Beings have complicated thinking process.
C. The brains of the idiot savants are partly impaired.
D. The reasons why people have wonderful skills vary.
2.Which of the following can be done by Rain Man?
A. He can play wonderful pieces of classical music.
B. He can guess out exactly the length of a mads life.
C. He can memorize the contents of the pictures fast.
D. He can count matches dropped on the floor quickly.
3.What can you infer from the passage?
A. Idiot savants have real talents for art and math.
B. Dr.Down is the first person who found idiot savants.
C. Few people wish to risk becoming savants by brain operations.
D. Intentional left brain impairments will surely lead to idiot savants.

高二英语单项填空中等难度题查看答案及解析
There is a man who is dying to find the way to success, but he doesn’t have an idea how to do it. One day, he meets a guru, a religious teacher, on the road. The man asks the guru, “Which way is to success?” The gum doesn’t speak, but points to a place off in the distance.
The man, thrilled by the prospect of quick and easy success, rushes off in that direction. Along the way, he is occupied in inking up something special but there is nothing. Suddenly there comes a loud splat(溅泼声). Eventually, the man limps back in rags, assuming he must have misinterpreted the message. Therefore, he returns to the guru for a reason. He repeats his question to the gum, who again points silently in the same direction.
The man was obedient to walk off once more. This time the splat is deafening, and when the man crawls back, he is bloody, broken and angry, “I asked you which way was to success,” he screams at the guru,” I followed the direction you pointed to. And all I got was being knocked down! No more of this pointing! Tell me why? Talk!”
Only then does the guru speak, and what he says is that “Success is that way. Just a little past the splat.”
1.Why does the man fail once more?
A. He is so stupid that he cannot find it.
B. The way to success does not exist in life.
C. The guru gave the wrong direction to him.
D. He does not make sense of the guru’s words.

Homework is a major part of going to school: It's your teachers' way of evaluating(评价) how much you understand of what's going on in class. 1. Luckily, you can do a few things to make homework less work.
Be sure you understand the homework.
Write your homework down in your notebook or day planner if you need to. 2. It's much easier to take a minute to ask the teacher during or after class than to struggle to remember later that night!
Use any extra time in school.
Many schools have study halls that are specifically designed to allow students to study. It's tempting (诱惑) to hang out with friends during study periods or unstructured (松散的) time. 3.____
Take a break.
4. So take some breaks while doing your homework. Sitting for too long without stretching or relaxing will make you less productive than if you stop every so often. Taking a 15-minute break every hour is a good idea for most people.
5.
If you don't finish your homework during school, think about how much you have left and what else is going on that day, and then budget your time. Most high-school students have between 1 and 3 hours of homework a night. If it's a heavy homework day and it seems like you've got an assignment in every subject but gym and lunch, you'll need to devote more time to homework. It's a good idea to come up with some kind of homework schedule, especially if you are involved in sports or activities or have an after-school job.
A.Pace yourself.
B.Settle down to do homework.
C.And it helps digest important concepts (概念).
D.Most people's attention spans (注意力持续时间) aren't very long.
E.Don't be afraid to ask questions about what's expected.
F.Once your homework is done, you can check over it if you have extra time.
G.But the more work you can get done in school, the less you'll have to do that night.

As technology develops, school students who are off class may have no fear of too much absence from class. A small robot may help those children recovering from a long-term illnesses in the hospital or at home. These children may feel isolated from their friends and classmates. The robot takes their place at school. Through the robot, the children can hear their teachers and friends. They also can take part in class from wherever they are recovering.
Anyone who has had a long term illness knows that recovering at home can be lonely. This can be especially true of children. They may feel left out. Now these children may have a high-tech friend to feel less alone. And that friend is a robot. The robot is called AV1. AV1 goes to school for a child who is at home while recovering from a long-term illness. And the child’s school friends must help. They carry the robot between classes and place the robot on the child’s desk.
A Norwegian company called No isolation created the robot. The co-founders of No Isolation are Karen Dolva and Marius Aabel. Dolva explains how the robot AV1 works. She says, from home, the child uses a tablet or phone to start the robot. Then they use the same device(设备)to control the robot’s movements. At school, the robot becomes the eyes, ears and voice of the child. The child can take part in classroom activities from wherever she/he is recovering-whether at home or from a hospital bed. The robot is equipped with speakers, microphones and cameras make communicating easy.

Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers.It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.
Human activity is not responsible for all water shortages. Drier climates are of course more likely to have droughts than areas with more rainfall,but in any case, good management can help to make sure there is enough water to meet our basic needs.
Thinking about the way we use water every day can make a big difference, too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live,but there's a lot we can do to lower the number.
You can take steps to save water in your home.To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.
1.Which of the following is most likely to lead to less groundwater?
A. Using river water. B. Throwing batteries away.
C. Paving parking lots. D. Throwing rubbish into lakes.
2.What can be inferred from the text?
A. All water shortages are due to human behavior.
B. It takes a lot of effort to meet our water needs.
C. There is much we can do to reduce family size.
D. The average family in America makes proper use of water.
3.The last paragraph is intended to________.
A. show us how to fix leaks at home
B. tell us how to run a dishwasher
C. prove what drinking glass is best for us
D. suggest what we do to save water at home
4.The text is mainly about________.
A. why paving roads reduces our water
B. how much we depend on water to live
C. why droughts occur more in dry climates
D. how human activity affects our water supply

Scientists at the University of Oxford have developed new artificial intelligence software to recognize the faces of chimpanzees in the wild. The new software will allow researchers to significantly cut back on time and resources spent analyzing video footage.
“For species like chimpanzees, which have complex social lives and live for many years, recording their behavior from short-term field research can only tell us so much.” says Dan Schofield, researcher and DPhil student at Oxford University’s Primate Models Lab. “By using the power of machine learning to unlock large video footage, it makes it feasible to measure behavior over the long term. Observing how the social lives of a group change over several generations become possible as well.”
The computer model was trained using over 10 million images from Kyoto University’s Primate Research Institute (PRI) video footage of wild chimpanzees in West Africa. The new software is the first to recognize individuals in a wide range of poses, performing with high accuracy in difficult conditions such as low lighting, poor image quality and movement blur (模糊).
“Access to this large video footage has allowed us to use cutting edge deep neural networks to train models at a scale that was previously not possible.” says Arsha Nagrani, co-author of the study and DPhil student in University of Oxford. “Additionally, our method differs from previous primate face recognition software in that it can be applied to raw video footage with limited manual intervention (人工干预) or pre-processing, saving hours of time and resources.”
The technology has potential for many uses, such as monitoring species for protection. Although the current application focused on chimpanzees, the software provided could be applied to other species, and help drive the adoption of artificial intelligence systems to solve a range of problems in the wildlife sciences.
“All our software is available open-source for the research community.” says Nagrani. “We hope that this will help researchers across other parts of the world apply the same cutting-edge techniques to their unique animal data sets. As a computer vision researcher, it is extremely satisfying to see these methods applied to solve real, challenging biodiversity (生物多样性) problems.”
“With an increasing biodiversity crisis and many of the world’s ecosystems under threat, the ability to closely monitor different species and populations using systems will be important for protection efforts, as well as animal behavior research.” adds Schofield. “Interdisciplinary cooperation like this have huge potential to make an impact, by finding solutions for old problems, and asking biological questions which were previously not available on a large scale.”
1.What’s the function of the new artificial intelligence software?
A.Analyzing video footage in difficult conditions.
B.Recognizing the faces of chimpanzees in the wild.
C.Cutting edge deep neural networks to train models at a scale.
D.Saving hours of time and resources without manual intervention.
2.What does the underlined word “feasible” in Paragraph 2 probably mean?
A.possible B.important
C.natural D.official
3.From the passage, we know that the artificial intelligence software could ________.
A.recognize individuals but not clearly
B.save time and resources only
C.help to protect different species
D.hardly solve biodiversity problems
4.What is the main purpose of the passage?
A.To introduce a new software.
B.To explain a measure.
C.To assess a project.
D.To describe a procedure.
