Usually people with better education are able to get better jobs,In other words,they have more chances to choose a good job while people with little or no education don’t.It seems that the purpose of education is to make people get jobs.But it isn’t true.

Some people may think that a person spends the best years of his life to get education only to make a living.This was probably one of reasons of education.In fact,if education is just a way of making a living,people don’t need to spend so much time in school. If people just want to make a living,they can get a short-time education.Subjects like history and geography need not be taught to everyone.Even language and math need not be taught in detail(详细地),either.It is clear that education is much more than teaching a man to get a way of living.

Education is mainly for improving a man. It is not only to teach him to speak, read and write,but also to develop his other abilities.It can make him a wise man and enjoy the achievements of humans.Education is to make a man lead to a better life.Educated people are expected to be able to listen to good music,read good books,watch plays and,most of all,take an interest in the world.

I would agree that making a good living is an important reason for education,but certainly not the most important one.

Have you ever had dreams about building a robot? Or putting together a spaceship? Or even seeing your face made out of chocolate? Done. All you need is a 3-D printer!

The possibilities of 3-D printing seem endless. All the user has to do is to design an object on the computer and choose a material to print in. The printers print in hundreds of different materials including glass, sugar and even skin! When the user presses “print”, the 3-D printer spreads the material layer by layer and like magic the object is produced.

The first 3-D printer was invented in 1986 by an American, Charles Hull. But 3-D printing has only become cheap enough recently for most people to use. Designers now use 3-D printing to create unusual things. The Dutch artist Dirk Vander Kooj prints furniture made from old fridges. And doctors have used 3-D printing to print human body parts! The Telegraph reported in February that scientists from Cornell Medical College even printed a man-made ear.

But like a lot of new technologies, if 3-D printing gets into the wrong hands, it can be dangerous. In 2011 a group of four men in the US used 3-D printing to produce ATM skimmers. These were placed on an ATM and stole over $400,000 from users of the ATM. It is terrible to think that criminals* like them might one day use a 3-D printer to print a gun.

But for better or for worse, 3-D printing has been put into use. In a few years, you’ll probably be wondering how you could ever live without your 3-D printer!
