At the end of every year, Time picks the best 25 inventions that are “making the world better and smarter”. Here we have picked three of this year’s inventions that could be a part of your life in the near future.
The levitating(悬浮的) lightbulb
This special lightbulb was invented by US artist and scientist Simon Morris. He got the idea of making a lightbulb float from hoverboards(悬浮滑板)，which he used to dream of having as a kid.
But the floating is not the most amazing part. The rejection force between the opposite ends of the magnets(磁铁)，which were put in the bottom of the bulb and in the wooden base, does the job. What’s new here is a technology called induction (电磁感应). It allows the lightbulb to get power from the base even they are not in contact.
Shoes that tie themselves
They’re not what you think-shoelaces that tie themselves in the way we tie them. Instead, the new shoes have small motors that control their laces. When you step in them, your feet will hit a sensor（传感器）in the shoes and the motor will automatically tighten the laces.
But the shoes weren’t just designed for lazy people’s needs. They could actually give athletes an advantage during competition. They are also useful for people who cannot move their arms or fingers easily.
The no-touch thermometer
Taking your body temperature usually means putting a thermometer (体温计) in your armpits (腋窝) and staying still for minutes. It may be easy for you, but it’s an impossible task for little kids.
Now, with the new thermometer, users can simply put it 2.5 centimeters from a patient’s forechead and press the button, and it can get the reading in two seconds.

In the past, teachers always kept on to explaining the points in class. Our students just listened and take notes. But now we often discuss and try to solve the problems raising by the teachers or ourselves. After class, we enjoy different kind of activities instead of doing endless homework. For example, we can read that we are interested. We can go to the library and surf the Internet for variously kinds of information. In my opinion, exploring study does not only help us learn much, but also make us to enjoy study and become masters of study.
