In a time when ivory poaching(偷猎)has gotten so bad that it threatens to wipe out several animal species,a young Dutch designer is creating "egalitarian(平等主义)jewelry" made of our very own ivory—teeth.

Lucie Majerus got the idea for her "human ivory" collection after having her wisdom teeth removed.She kept them and soon realized they would make great material for a jewelry collection."Why wouldn't we value our own material instead of the precious material from other species?And what if we mine our own ivory and turn it into pearls?"she asks.

Her own teeth became a ring,but in order to create a whole collection,she needed more material,and since having more of her teeth removed wasn't a very pleasant choice,she asked her dentist to save his patient's unwanted teeth.Most people choose not to keep their pulled teeth,so they are usually donated to dentistry schools.Majerus also received the lost teeth of two of-her teachers at Design Academy Eindhoven,so she had a nice supply of human ivory to experiment with.

To turn human teeth into attractive pieces of jewelry,Lucie Majerus first bleaches(漂白)them,and then uses a stone polishing machine to shape the teeth into various shapes.

Majerus displayed her human ivory jewelry collection at this year's Dutch Design Week,and claims that people's reaction was mostly positive."Surprisingly,most people aren't frightened at the sight of the jewelry,but really like the idea,"Majerus told Fast Co Design."Some regret that they didn't keep their tooth at the dentist and some,who will have teeth taken out soon,are now looking forward to it."

Spring soccer season is under way,and many youth leagues are playing under new safety rules.In November,the US Soccer Federation said that players on its teams who are 10 or younger are no longer allowed to head the ball. Players ages 11 to 13 have limits on how often they can practice heading.The new rules are made to prevent kids from getting concussions(脑震荡)—injuries caused by a blow to the head that shakes the brain.Common problems include headaches and dizziness.Severe concussions can lead to long brain damage.

Heading the ball can be one of the riskiest parts of soccer.Sometimes the force of hitting the ball with their heads gives players concussions.But more often,players receive concussions when they accidentally knock heads with other players and hit their heads on the grass."More concussions happen during the act of heading than any other action in soccer,"explains Dr.Robert Cantu,an expert on brain injuries.

So far,the new rules are made only to teams that are part of the US Soccer Federation.But the group says it hopes other leagues will soon follow its example.

Former US soccer star Brandi Chastain is one of the leaders of the activity to ban heading in Youth soccer.She applauds the rule change.Last month,Chastain showed her determination of learning more about the effects of heading when she promised to donate her brain to science after she dies.

"If there's any information to be gathered on the study of someone like me,who has played soccer for 40 years,it feels like my responsibility,"Chastain told The New York Times.

Smartphones,tablets and laptops make it easy for people to work on the go,.but traditionally,printers have been cumbersome to move out of the office.However,the new Zuta Pocket Printer will enable people to print anywhere.

A few changes about how a teacher runs a classroom can make a huge effect on how concentrated students will be in that classroom.It's an issue every teacher has to face,1.Here are just a few of my strategies.

●Rearrange(重新安排)Seats.

I did the seat rearrangement because class conversation had become dull,and students just seemed to be there but not actually there.2.I had all of my students pick new seats at the tables.The rules were simple.They could not sit with more than one other person they'd already sat with,and it had to be at a different table.

●Take over A Lesson.

Once in a while,it can be fun to let the students take over a lesson in a unit.Let them become the teachers,and the teacher becomes the student.You can provide the topic they need to cover.3.

●Have Open Projects.

Open projects have been very successful in my class.4.I used to dictate every part of my project assignments.Students would ask to do things a little differently.And I'd give in,surprised that their ideas were better than mine.

5.

Sometimes teachers forget to bring the fun to the classroom.We try so hard to cover the courses for our students until they break down.Sometimes it's good to just set things aside for a day or two and have some fun.

A.Have fun.

B.Listen carefully.

C.But it can be solved in some very simple ways.

D.Let the students choose the topic and teach whatever they want.

E.It's one of the simplest ways to rearrange a class and get things going again.

F.They get to deal with the material in a way that is refreshing and new to them.

G.I've found that the more choices I gave my students, the better the projects have been
