Modern inventions make our life easier and more interesting than before. Let’s take a look at some inventions.

A new kind of enzyme(酶)

Scientists in Britain and the United States have found a new kind of enzyme that eats plastics. With its help, plastics can be turned into smaller parts and go away quickly. It can stop plastics from being burned everywhere. Scientists believe that it can solve the problem of plastic pollution in the future.

Social robot

Can robots talk to us like humans? Jibo, a robot made in US, can talk with you. The robot has a big, round head and a big body with no eyes or mouth. It uses animated icons (动画图标) to show emotions(情绪). It just seems like a real human. Right now, Jibo can only do some easy things, like taking photos and reading news to you. But it may learn to do new things in the future.

Spark

Spark is a new drone(无人驾驶飞机) made by a Chinese company in Shenzhen. It can help people take photos and videos. Spark might be the smallest drone ever made. When folded, it is as small as a Coke can. The coolest part is that users can control the small drone just by using hand gestures. For example, if you wave your hand from left to right, the drone will fly in the same way. When you want it to land you just put your hand out.

The drone will come to you and land on your hand.
