Some cool inventions are listed in Science Magazine's 25 best inventions of 2018. They are "making the world better, smarter and -- in some cases -- a little more fun", according to the magazine's website. Do you want to lean more about some of the inventions? Let's find out. ● Spark Spark is a new type of drones (飞行器) made by a Chinese company (公司) in Shenzhen called DJI. It can help people take photos and videos. Spark might be the smallest drone ever made. When folded, it is as small as a can of cola (可乐罐). The coolest part is that users can control the small drone just by using hand gestures(手势). For example, if you wave (挥动) your hand from left to right, the drone will fly in the same direction. When you want it to land, you just put your hand out. The drone will come to you and land on your hand. ● Social Robot Robots may not be good communicators. But Jibo, made by US company Jibo Inc, may be different. With a big, round head and round, fat body, Jibo looks like a cartoon character. As soon as you say, "Hey, Jibo." It will giggle(咯咯地笑), dance and turn to face you. When it talks to you, it moves its head and body naturally to communicate with you. Although it has no eyes or mouth, Jibo uses animated icons (生动的表情), such as a smile icon, to show emotions. Right now Jibo can only do some basic things, like taking photos or reading the news to you. But it may learn to do more in the future. 32. According to the passage, we know _______. A.
