Taking a picture of your tongue with a mobile phone could soon instantly tell you how healthy you are. Researchers believe the images can reveal important information about a patient’s health and even give them early warning of serious illness.
A team at the University of Missouri is developing a system that can analyze pictures using a 5,000-year-old Chinese principle, which is based on the flow and balance of positive and negative energies in the body, and uses the tongue as a key to learning about a person’s physical health, or “zheng” according to Chinese medicine.
“Within a year, our goal is to create an application for smart phones that will allow anyone to take a photo of their tongue and learn the status of their zheng,” said Dong Xu, chair of MU’s Computer Science Department in the College of Engineering and the co-author of the latest study.
The software analyzes images based on the tongue’s color and coating to distinguish between tongues showing signs of “hot” or “cold” zheng. Shades of red and yellow are associated with hot zheng, whereas a white coating on the tongue is a sign of cold zheng.
“Hot and cold zheng doesn’t refer directly to body temperature,” said Xu, “Rather, it refers to a series of symptoms associated with the state of the body as a whole.”
For the study, 263 gastritis(胃炎) patients and 48 healthy volunteers had their tongues analyzed. The gastritis patients were classified by whether they showed infection by a certain bacteria as well as the intensity of their gastritis symptoms. In addition, most of the gastritis patients had been previously classified with either hot or cold zheng. This allowed the researchers to test the accuracy of the software’s analysis.
“Our software is able to classify people based on their zheng status. And as we continue to work on the software we hope to improve its ability,” said another co-author Ye Duan, “Eventually everyone will be able to use this tool at home using webcams or smart phone applications, which will allow them to monitor their zheng and get an early warning about possible ailments.”

[详细]举一反三
Parents should stop blaming themselves because there"s not a lot they can do about it. I mean the teenager problem. Whatever you do or however you choose to deal with it, at certain times a wonderful, reasonable and helpful child will turn into a terrible animal.
I"ve seen friends deal with it in all kinds of different ways. One strict mother insisted that her son, right from a child, should stand up whenever anyone entered the room, open doors and shake hands like a gentleman. I saw him last week when I called round. Sprawling himself on the sofa in full length, he made no attempt to turn off the loud TV he was watching as I walked in, and his greeting was no more than a quick glance at me. His mother was ashamed. "I don"t know what to do with him these days," she said. "He"s forgotten all the manners we taught him."
He hasn"t forgotten them. He" s just decided that he" s not going to use them. She confessed that she would like to come up behind him and throw him down from the sofa onto the floor.
Another good friend of mine let her two daughters climb all over the furniture, reach across the table, stare at me and say, "I don"t like your dress; it"s ugly." One of the daughters has recently been driven out of school. The other has left home.
"Where did we go wrong?" her parents are now very sad. Probably nowhere much. At least, no more than the rest of that unfortunate race, parents.

All parents know that one of their most important tasks is to prepare their children for an independent life，but any parent can tell you that it’s hard to let go of your children．That balance between keeping your children safe and allowing them to learn from their own mistakes can be heartbreaking．Years of experience means that parents often do know best，but on the other hand，the young，being less bound by tradition，are often more creative，more able to find new solutions to old problems．Revolutions are led by the young．
Good teachers make the growth of critical （批判性的） thinking easier in their students，only to find that this can lead to a questioning of the teachers’ basic beliefs．Schools encourage parents to become involved，but are often embarrassed when parents have reservations about some of the educational methods being used．Governments encourage unimportant groups to empower themselves in order to participate fully in the development process．And they are often surprised when the new leaders of these groups turn around and attack the policies of that same government．The rebellions （叛逆的）young and the newly unimportant groups are important in social development．They are not necessarily representatives of those they want to represent or not realistic in their demands，but their voices must be heard．
Good parents know that just forbidding particular behaviors does not prevent their children from finding ways to engage in these forbidden activities．Indeed，sometimes the forbidden fruit is more inviting，just because it is not accepted by authority．Parents must work with their children to educate them on the facts，know as much as possible about he lives of their children，provide a good example，encourage more wholesome activities but also support their children when they don’t follow what is expected of them．But the most important point is that they also need to learn how to let go．
小题1:By saying “Revolutions are led by the young”，the author indicates that young people are more___________________．| A．conventional | B．creative | | C．realistic | D．heartbreaking |

小题3:In order to educate children well，parents should_________________．| A．forbid particular behaviors in their daily life | | B．know as much as possible as their children | | C．educate them with facts and expect much of them | | D．know them well and set a good example to them |
小题4:From the passage we can learn that the author prefers ___________________．| A．free parenting | B．traditional parenting | | C．smart parenting | D．critical parenting |

Our body clock，or natural body rhythm，influences our energy and alertness．Paying attention to it can help us choose the suitable time of day when we best perform specific tasks．
The reality，however，is that most of us organize their time around work demands，school deadlines，commuting or social events．Doing whatever your body feels like doing is a luxury in today"s fast-paced modem society．
But that doesn"t mean it isn"t worth trying．Obeying our body clock has significant health benefits．Disrupting our natural body rhythm，on the other hand，has been linked to problems such as depression，obesity，or headache，says Steve Key，a biology professor．
When the body clock can synchronize（使……同步）the rhythms of its natural processes，it “gives us an advantage in daily life”，says Key．
According to him，when it comes to cognitive（认知的）work，most adults perform best in the late morning．As our body temperature starts to rise just before awakening in the morning and continues to increase until midday，our memory，alertness and concentration gradually improve．
However，he adds，our ability to concentrate typically starts to decrease soon thereafter．Most of us are more easily distracted（分心）between noon and 4 pm．
Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm，making that a good time for a nap．
Surprisingly, tiredness may increase our creative powers．For most adults，problems that require open ended thinking are often best dealt with in the evening when they are tired， according to a study in the journal Thinking & Reasoning．
When choosing a time of day to exercise，paying attention to your body clock can improve results．Physical performance is usually best from about 3 to 6 pm，says Michael Smolensky，a professor of biomedical engineering．
Of course, not everyone"s body clock is the same，making it even harder to synchronize natural rhythms with daily plans．
小题1:If we know our natural body rhythm well, we can ．| A．find out the suitable time to do specific tasks | | B．organize our time around work demands | | C．do whatever our body feels like doing | | D．be sure to be healthy |
小题2:Which of the following is NOT true?| A．Our alertness is influenced by our natural body rhythm | | B．Doing whatever your body feels like is very difficult in our modem society． | | C．Obeying our body clock is good for our health． | | D．Disrupting our natural body rhythm can lead to obesity． |
小题3:According to Steve Key，which of the following is NOT true?| A．When our body clock synchronizes the rhythms of its natural processes，we can do better． | | B．When it comes to cognitive（认知的）work，most people perform best in the late morning． | | C．As body temperature rises before awakening in the morning，our concentration gradually improves． | | D．We concentrate better in the late morning than between noon and 4 pm． |
小题4:Inspiration（灵感）to solve a difficult problem will most probably come to us ．| A．when we get up in the morning | | B．when we are tired in the evening | | C．when we are full of energy in the late morning | | D．when we are asleep at night |
小题5:Which of the following can be the suitable title for the passage?| A．What is natural body rhythm? | | B．Natural body rhythm is good for us． | | C．Something about natural body rhythm． | | D．The latest research about natural body rhythm． |

A noted American psychologist once remarked that childhood is a magical period in one’s life．Indeed it is, for during one undergoes a step-by-step transformation not only in mental capacity, but also in physical and verbal skills．Each step an increase in the difficulty of a child’s conceptual and learning abilities．During the early stages of childhood, from infancy to about five, the child learns skills including using the toilet, bathing and dressing himself independently．At this stage, he also learns to be very observant, curious, imaginative and creative．His ability to remember things also at this stage． He remembers details that an adult may have difficulty in remembering．Gradually , he learns elementary skills in problem-solving．At school, particular in classes, the child is especially creative．Given a piece of paper and some colored pencils, he draws a variety of from his surroundings as well as from his circle．It is not surprising to see a child draw a monster to represent an abusive father, and an angel to represent a loving and caring mother．
As he graduates to the later stages of childhood bordering on the teenage years, the child learns the of human relations and socialization by interacting with his peers—his friends and schoolmates． He also learns to with new life situations, including dates and part-time work． Given a tight schedule of schoolwork, the child learns to prepare his own schedules of work and play; the more________ and less serious ones manage to take time out of their busy schedules of assignments, reports and tests and examinations to go with their friends on relaxation entertainment．
