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.

A. in; on B. on; in C. on; on D. in; in

C 【解析】句意：他于1991年9月3日去了上海，去年一个寒冷的早晨回来了。考查介词辨析题。in泛指一般意义的上午、下午或晚上以及月或年等较长的时间；on表示星期几或某一特定的日期。本句September 3, 1991是具体的某年某月某日，不是泛指；a cold morning（一个寒冷的早晨），表示某个季节的上午下午晚上，都需用介词on。根据句意语境，可知选C。
