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.”
小题1: The software mentioned in the passage is based on ________.

A．the latest development of smart phones

B．a traditional Chinese medical principle

C．the changes in one’s flow and energy

D．symptoms related with the state of the body

小题2:According to Chinese medicine, zheng refers to ________.

The library is one of the most popular places at a western university.Students turn to it for research，conversations about class，and many other services.
Compared with Chinese libraries，college libraries in the US and UK tend to offer more resources.A postgraduate at Yale University can borrow as many as 225 books at a time.
In addition to borrowing books，there are online and electronic resources.These include a database search of popular and academic material，such as LexisNexis Academic，which offers items from newspapers and magazines.
Although books and articles are the items that students ask for most frequently，some libraries provide audio and video recordings，maps and sheet music(活页乐谱)．At some schools，teachers and tutors put electronic copies of their teaching PPTs on the library web to give easier access for students.
Another useful service in western college libraries is the Interlibrary Loan.This allows a student at one school to borrow books from another school.The loan request is made through the student’s college library，which gets the book，gives it to the user，and arranges for its return.
Technology has brought more services to students and has made libraries attractive.Some universities have services for students to send messages through the computer or mobile texts to ask the library staff for information.
Earlier this year，Harvard University introduced a new Scan and Deliver service，allowing students to make requests for parts of books and articles.Requests made through the system are handled by library staff.The student receives an email with an Internet link to the scanned pages.The service is free and all material comes within four days.
It used to be that libraries didn’t allow food or drinks.But that rule is changing and many of them now contain a café so students can spend as much time as they want in the library.
Actually，some US university libraries are now allnight affairs，or have at least one study room open all night.
小题1:In western college libraries a postgraduate can ________.

A．have a free drink or a meal

B．borrow as many books as they want

C．ask questions and get answers from their tutors

D．access not only books but other study resources

小题2:LexisNexis Academic is the name of a ________.

A huge cloud of dust rose and an overpass disappeared. This was the scene in Zhuzhou，Hunan Province on May 17.Nine people were killed and 16 injured.
Things were similar last year in the Sichuan earthquake. Thousands of people were buried in the ruins and lost their lives. What if we could have warned them?
People are always racking their brains to find a way of preventing buildings’ collapse. Better materials and technology help，but they are not a solution.
Just like humans，a building has its own life cycle from “birth” to “death”．If we know when a building is going to collapse，we can repair it in advance or get out of it before it falls.
Now，scientists at the University of Illinois have developed a material that turns red before it breaks. The invention could be used in things like climbing ropes or bridge supports.
The research was led by Nancy Sottos，a professor at the university’s Beckman Institute，and Douglas Davis，a graduate research assistant.
The secret behind the colorchanging material is a type of molecule (分子)．A molecule is a group of atoms held together by chemical bonds. Imagine you and your friends standing in a circle，holding hands. Each person stands for one atom，your hands represent the bonds，and the entire circle represents a molecule. If one person lets go of his or her hands，the molecule changes color.
The research team put the molecule into a soft material. When the researchers stretched the material，it turned bright red for a few seconds before it broke into two pieces. When they repeatedly stretched and relaxed the material，without breaking it，it only turned a little red.
The major problem is that light can get rid of the red color. When the team shone bright light on the molecule，the broken bond was fixed，and the color disappeared.
If the bright light keeps the red color from appearing，the material’s warning system will be useless. Scientists still have a lot of work to do before the colorchanging molecules can be used outside the lab.
小题1:What does the passage mainly introduce?

A．The collapse of an overpass in Zhuzhou，Hunan Province.

B．The Sichuan earthquake

C．A material that turns red before it breaks.

D．A way of preventing building from collapsing.

小题2:The underlined words “racking their brains” in the third paragraph mean ________.

A．suffering a lot	B．collecting beyond imagination
C．losing a lot	D．thinking very hard

小题3:Which of the following is a WRONG statement?

A．Thousands of people died from the collapse of buildings in the Sichuan earthquake because they hadn’t been warned.

B．There is no building that will never collapse.

C．A new material has been applied to buildings to warn people of collapse.

D．A colorchanging material can turn red before it breaks.

小题4:What can we infer from the passage?

A．The colorchanging molecules are certain to be used outside the lab.

B．There will be no collapse with the help of the colorchanging material.

C．There is a long way to go before the material can be applied.

D．The problem caused by bright light will be solved by scientists.

It’s five minutes before the exam and you are in a state of panic. You just have to pass it, but how? You didn’t even open the book the night before and you hear a voice in your head saying “Cheat, cheat ...” So what are you going to do, ignore it and fail or go for it? It’s a tough decision many students must make.
Most young people believe that cheating is wrong. However, they have cheated at least once in their high school years. So, why do they do it? Are they too lazy to study? Perhaps, it’s not as simple as that. According to some experts, one main reason why students cheat is that they see their friends get away with it. It’s an easy way out. They avoid embarrassment and their parents’ anger for not doing well in an exam. Another reason is that students think it’s OK to cheat if the subject isn’t important for their future career. What’s more, most students have to put up with the pressure of getting into university. They need to get good marks to carry on with their studies. This means that there will always be students who will do anything for a better mark.
It has never been easier to cheat than it is today. With all the technology available, students needn’t cheat by looking over their shoulders anymore. They use mobile phones to send answers to each other during a test. There is also the Internet. With hundreds of websites, students don’t have to worry because they can find lots of material which they can copy and use in projects. There are even tips on the art of cheating in exams.
Obviously, if you get caught cheating, you fail the exam or the subject. But it doesn’t really matter whether you get caught or not. What’s important is that it’s wrong. You mustn’t cheat because cheating is a lie. It deceives (欺骗) people into thinking you know more than you actually do. How can you be proud of something you have achieved through cheating? In the end, it’s not about deceiving your teachers and your parents, but about fooling yourself that you can do something you really can’t.
小题1:The tough decision that many students have to make before an exam is .

A．whether to cheat or not	B．what to do if they fail
C．how to cheat	D．how to keep calm

小题2:According to the experts, why do some students cheat?

A．The subjects are important for their future.	B．They are too lazy to study.
C．Cheating can help them please their parents.	D．Their friends ask them to cheat.

小题3:The worst thing about cheating is that .

A．you cheat others and yourself

B．you can get caught and fail

C．you give others a bad impression

D．your teacher will inform your parents

小题4:Which sentence best summarizes the whole text?

A．Cheating can be explained but not excused.

B．Technology has made cheating easier.

C．Students cheat to get into university.

D．Cheating is a social and psychological problem.

Coffee is a powerful beverage．On a personal level，it helps keep US awake and active．On a much broader level，it has helped shape our history and continues to shape our culture．
Coffee didn’t take off until the l400s when people figured out they could roast its seeds．By the l500s，the drink had spread to coffeehouses across the Arab world．Within another l50 years，it took Europe by storm．
“It actually had a major impact on the rise of business，” historian Mark Pendergrast says．Coffeehouses became a spot not just to enjoy a cup but to exchange ideas．The insurer Lloyd’s of London was founded hundreds of years ago in one of London’s 2,000 coffeehouses．Literature，newspapers and even the works of great composers like Bach and Beethoven were also spawned(涌现)in coffeehouses．
It is often said that after the Boston Tea Party of l773，when American colonists attacked British tea ships and threw boxes of tea into the harbor，Americans universally switched over to drinking coffee．In a letter John Adams wrote to his wife，Abigail，the Founding Father claims his love of tea but says he will have to learn to embrace coffee instead，because drinking tea had become a symbol of not loving the country．
For all the upsides coffee has brought the modern world，it also led to its fair share of downsides，too．Europeans carried coffee with them as they colonized various parts of the world，and this frequently meant they enslaved people in order to grow it．In Brazil — where slavery was legal until l888 — coffee plantations would use slash-and-burn agriculture，tearing down rain forests and planting coffee trees．Once the soil had been exhausted，growers would move on to another place．
And yet，coffee，as Pendergrast says，”had a very good impact in many ways on our civilization，even though it was，for a long time，grown by slaves．”
小题1:Why did people enjoy going to coffeehouses?

A．Because it was a fashion to drink coffee．

B．Because coffeehouses provided a better flavor．

C．Because they could stay awake and active there．

D．Because they could exchange ideas there．

小题2:What can we learn from the fourth paragraph?

A．American colonists made great profits by trading in coffee．

B．Tea was regarded as a symbol of loving one’s country．

C．Coffee became very popular after the incident in Boston．

D．John Adams was the Founding Father of the Tea Party．

小题3:In the fifth paragraph．the writer points out that __________ .

A．Coffee plantation was closely connected with slavery

B．coffee plantation led to outdated agriculture in Brazil

C．slavery in Brazil had been against the law until l888

D．slavery was responsible for the damage to rainforests

小题4:What is mainly talked about in this passage?

B．Important Roles that coffee played in history．

C．How coffee became the most popular beverage．

D．How coffee affected America’s independence．

The color red often means danger --- and by paying attention, accidents can be prevented. At railroad crossings, flashing red fights warn cars to stay back. A red light at a traffic crossing tells cars to stop, so they don't run into other cars.
In the future, the color red also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports --- or other kinds of materials --- could one day contain a color-changing material. It will turn red before a structure collapses(倒塌) or falls apart.
The secret behind the color-changing material is a particular type of molecule(分子). Molecules come in all shapes and sizes, and make up everything you can see, touch or feel. How a molecule behaves depends on what kinds of atoms(原子) it contains, and how they're held together.
To get a rough picture of one way atoms are held together in a molecule, imagine you and your friends standing in a large circle, holding hands. Each person represents one atom, your clasped hands represent the bond, and the entire circle represents a molecule.
The molecule being used to turn the material red is called mechanophore(机械响应性聚合物). When one chemical bond in the mechanophore molecule breaks, the rest of the molecule turns red.
There is a way to get rid of~ the red color: light. When a bright light is shone on the mechanophore, the broken bond is fixed and the red color disappears. This "self-healing" may be a problem for engineers who want to use the color-changer in big construction projects that will be outside, in the sunlight. And if bright light keeps the red color from appearing, then the mechanophore's warning system will be useless.
Scientists still have a lot of work to do before the color-changing molecules can be used outside the lab. If mechanophore can be used in the real world, they are suggested to be employed in a new kind of paint.
小题1:The first paragraph mainly tells us __________.

A．the color red is widely used in our life

B．how to prevent car accidents

C．the color is an important signal of warning

D．how to use color red

小题2:The color red will be used at construction sites to _________.

A．tell different materials used in the building

B．warn people that the building is dangerous

C．make the building more beautiful

D．tell people the building is under construction

小题3:The example given in the fourth paragraph is to show _________.

A．the way atoms are held together in a molecule

B．how a molecule behaves in an object

C．how to play an old game

D．how people get along with each other

小题4:What can make the mechanophore’s warning system ineffective?

A．Paints

B．Water

C．Poor building materials

Students who date in middle school have significantly worse study skills. They are four times more likely to drop out of school and report twice as much alcohol and tobacco use as their single classmates, according to new research from the University of Georgia.
"Romantic relationships are a trademark of adolescence, but very few studies have examined how adolescents differ in the development of these relationships," said Pamela Orpinas, study author and professor in the College of Public Health and head of the Department of Health Promotion and Behavior.
Orpinas followed a group of 624 students over a seven-year period from 6th to 12th grade.
Each year, the group of students completed a survey indicating whether they had dated and reported the frequency of different behaviors, including the use of drugs and alcohol. Their teachers completed questionnaires about the students’ academic efforts. He found some students never or hardly ever reported dating from middle to high school, and these students had consistently the best study skills according to their teachers. Other students dated infrequently in middle school but increased the frequency of dating in high school.
"At all points in time, teachers rated the students who reported the lowest frequency of dating as having the best study skills and the students with the highest dating as having the worst study skills,” according to the journal article. Study skills refer to behaviors that lead to academic success such as doing work for extra credit being well organized, finishing homework, working hard and reading assigned chapters.
"Dating a classmate may have the same emotional complications of dating a co-worker," Orpinas said, "When the couple break up, they have to continue to see each other in class and perhaps witness the ex-partner dating someone else. It is reasonable to think this could be linked to depression and divert attention from studying.”
“Dating should not be considered a ceremony of growth in middle school,” Orpinas concluded.
小题1:According to the passage, students who date in middle school may_____

A．have poorer academic performances

B．be more likely to hurl others

C．enjoy better school lives

D．are less likely to use alcohol and tobacco

小题2:When doing his study, Orpinas_____.

A．followed a group of students of 6th and 12th grade

B．completed a survey and a report each year

C．completed questionnaires about the students’ academic efforts

D．found that the students’ study skills have connection with their frequency of dating

小题3:Study skills may include the following behaviors and qualities Except_____

A．being diligent	B．being well organized
C． being kind and helpful	D．finishing assigned schoolwork

小题4:What can possibly happen to the school couples after they break up?

A．They don’t want to see each other any longer.

B．Their attention to studying will be affected.

C．They will miss their ex-partners sometimes

D．They will think it reasonable to get depressed.

小题5:Orpinas’ attitude towards dating in middle school is_____

A．supportive

B．positive

C．negative

D．indifferent
