Most people know precious gemstones (寶石) by their appearances. An emerald flashes deep green, a ruby seems to hold a red fire inside, and a diamond shines like a star. It’s more difficult to tell where the gem was mined, since a diamond from Australia or Arkansas may appear the same to one from the Democratic Republic of the Congo. However, recently, a team of scientists has found a way to identify a gemstone’s origin.
Beneath the surface of a gemstone, on the tiny level of atoms and molecules, lie clues to its origin. At this year’s meeting of the Geological Society of America in Minneapolis, Catherine McManus reported on a technique that uses lasers to clarify these clues and identify a stone’s homeland. McManus directs scientific research at Materialytics, in Killeen, Texas. The company is developing the technique. “With enough data, we could identify which country, which mining place, even the individual mine a gemstone comes from,” McManus told Science News.
Some gemstones, including many diamonds, come from war-torn countries. Sales of those “blood minerals” may encourage violent civil wars where innocent people are injured or killed. In an effort to reduce the trade in blood minerals, the U.S. government passed law in July 2010 that requires companies that sell gemstones to determine the origins of their stones.
To figure out where gemstones come from, McManus and her team focus a powerful laser on a small sample of the gemstone. The technique is called laser-induced breakdown spectroscopy. Just as heat can turn ice into water or water into steam, energy from the laser changes the state of matter of the stone. The laser changes a miniscule part of the gemstone into plasma, a gas state of matter in which tiny particles called electrons separate from atoms.
The plasma, which is superhot, produces a light pattern. (The science of analyzing this kind of light pattern is called spectroscopy.) Different elements produce different patterns, but McManus and her team say that gemstones from the same area produce similar patterns. Materialytics has already collected patterns from thousands of gemstones, including more than 200 from diamonds. They can compare the light pattern from an unknown gemstone to patterns they do know and look for a match. The light pattern acts like a signature, telling the researchers the origin of the gemstone.
In a small test, the laser technique correctly identified the origins of 95 out of every 100 diamonds. For gemstones like emeralds and rubies, the technique proved successful for 98 out of every 100 stones. The scientists need to collect and analyze more samples, including those from war-torn countries, before the tool is ready for commercial use.
Scientists like Barbara Dutrow, a mineralogist from Louisiana State University in Baton Rouge, find the technique exciting. “This is a basic new tool that could provide a better fingerprint of a material from a particular locality,” she told Science News.

EVERYBODY in this world is different from one another. But do you know that understanding differences can help you better manage your money?
As we grow up, we gradually develop a set of our own values or beliefs. These are influenced by society, our family, the education we receive and so on. Once this value system is set up, it’s not easy to change later in life.
Financial experts say that everyone also has their own belief of how to manage their finances. This is part of our value system and it has a great impact on the way we look after our money.
According to our different values, experts put us in three categories. They are: the ant, the cricket and the snail.
The ant—works first
Just like ants who work heart and soul in summer in order to store food for winter, these people don’t care about enjoying the moment. They work very hard and save money they earn so that they can enjoy life when they get old and retire. The ant loves to save but they could make more out of their money if they were willing to invest in some funds and stocks with low risk.
The cricket—fun first
The cricket wants to enjoy everything now and doesn’t think too much about the future. They even borrow money when they really want something. Many young people now belong to this group. These people have little savings. When they get old, they might have problems. They should learn to save and buy insurance.
The snail—lives under pressure
The snail refers to people who make life difficult for themselves. They take big long-term loans from the bank in order to buy things such as luxury houses. They are happy to take big loans even though they are not sure they can afford it. This can cause problems in the future. They should plan more carefully.
1.We can learn from the text that _____.
A. spending money is a wiser way
B. your way of managing money is a reflection of your value or belief
C. saving money is a good way to manage money
D. we spend money because we have earned it
2. Of the three types of people, the one that has no weakness is _____.
A. the cricket B. none of them
C. the snail D. the ant
3.If you had three dollars, you would spend all of it. Which type do you belong to?
A. None of them B. The snail
C. The ant D. The cricket
4. The text tells us mainly about _____.
A. spending nature
B. living behaviors of small animal
C. our own values and beliefs
D. understanding differences

The displays of bad temper are nothing new in kindergarten and first grade, but the behavior of a 6-year-old girl this fall at a school in Fort Worth, Texas, had even the most experienced staff members wanting to run for cover. Asked to put a toy away, the youngster began to scream. Told to calm down, she knocked over her desk and crawled(爬行) under the teacher’s desk, kicking it and throwing out the contents of the drawers. Then things really began to worsen. Still screaming, the child stood up and began casting books at her terrified classmates, who had to be accompanied to safety.
Just a bad day at school? More like a bad season. The desk-throwing incident followed scores of other crazy acts by some of the youngest Fort Worth students at schools across the district, and even the country. There have been an increasing number of kindergartners and first-graders with violent behavior and it has become an alarming trend.
The youngest school kids are acting out in really ridiculous ways and violence is getting younger and younger. Why? Educators and psychologist argue that they are witnessing the result of a number of social trends that have come together in a most unfortunate way. Many mention economic stress, which has parents working longer hours than ever before, kids spending more time in day care and everyone coming home too tired to engage in the kind of relationships that build social skills. In addition, many educators worry about rising academic pressure in kindergarten and first grade as the students have to take the yearly tests demanded by the No Child Left Behind Act. They believe that even more important than early reading is the learning of play skills. Other experts also point out that violent behavior in children has been closely linked to exposure to violence on TV and in movies, video games and other media. They insist schools try to teach kids what they have failed to learn at home, for example, having varieties of anti-violence and character-education programs, instructing children to interact with people who love them and teaching them how to behave.
1.The author leads in the topic of the passage with .
A. detailed examples B. scientific analysis
C. satisfactory evidence D. rich imagination
2.The second paragraph tells us that .
A. autumn is considered as a bad season for the youngest school kids
B. Fort Worth students set good example to their peers in the district
C. the problem of kids’ violent behaviors is too serious to be ignored

a. economic stress
b. academic pressure
c. lack of interaction with parents
d. ill personality
e. exposure to media violence
A. a, b, d B. a, c, d
C. b, c, e D. b, d, e
4.The passage mainly discusses about .
A. causes and solutions of school violent behaviors
B. student behavior management in the digital age
C. kids’ exposure to violence on TV and in movies
D. functions of character-education programs
