1 . Think about things around you when you get up in the morning: the alarm clock, toothbrush, toile, coffee maker, and shower heads… What do these things have in common? They are all inventions. They come in all shapes, sizes and varieties. And their inventors were from diverse backgrounds. Sure, many scientists have made discoveries and turned those discoveries into inventions. However, that doesn’t mean you must be a scientist to be an inventor.
We often hear that necessity is the mother of invention, and it means that people often identify one of their needs and then try to meet that need. Sometimes the only way to meet that need is to invent a new product!
Think about all of the musical instruments in the world. Now think of all the products that go along with those instruments. Instead of scientists, many of those products were invented by musicians. They discovered a need and then invented a product to satisfy it. They may have thought scientifically about the product. They may have had help from a scientist, but many people have shown that inventors can come from any background.
Non-scientific approaches can help develop new inventions. Although thinking scientifically is often a necessity, it can also be helpful to think out of the box. We often get used to doing things the same way and thinking that some ideas won’t work, which makes us stop thinking about new things. But if we keep thinking, we might discover something amazing. That is why some inventors can come from a variety of non-scientific backgrounds. For example a poet and an astronomer both look at the sky, but they see it differently. The poet might have ideas about a problem the astronomer would never consider.
See? You don’t have to be a scientist to be an inventor. Somehow, everyone can invent something.

4 . Thomas, 13, and his friends Mark and Josh had a fantastic idea. Why not play a game of football ... on a trampoline(蹦床)?
At first, it was great fun. Then Mark stumbled(绊倒), landing directly on Thomas’s leg. Thomas howled in pain.
Even if you’ve never been injured on a trampoline, chances are you know someone who has. There were nearly 95,000 trampoline-related injuries, in 2012 alone.
These injuries are such an enormous problem that the American Academy of Pediatrics (AAP), a group of doctors who specialize in treating children and adolescents, said in a 2012 study that trampolines should never be used at home or on playgrounds. Never.
“This is not a toy. It’s a piece of equipment,” says Dr. Michele LaBotz, an author of the AAPstudy.
Indeed, when trampolines were invented in the 1930s, they were intended for use by professional acrobats(杂技演员). Over time, trampolines caught on with the public, and now 900,000 are sold each year, most of them for recreational use.
Part of trampolines’ appeal is that despite the risks, they provide good exercise. You get a heart-pumping aerobic(有氧的) workout, like you do when running or dancing. And young people need all the exercise they can get.
Still, trampolines can be dangerous — and not just for kids who fall off. Kids are also getting hurt on the springs and when they strike against each other. Serious injuries to the head and neck have been reported. One out of every 200 trampoline injuries leads to permanent brain damage.
Bouncing on a trampoline is clearly risky. But then, every athletic activity involves risk. Kids fall off bikes and skateboards all the time. As with any sport, kids on a trampoline can protect themselves. For instance: Never allow more than one person on a trampoline at a time. (About 75 percent of injuries result from having multiple jumpers at once.) And always have adult supervision.
