Pencils weren’t popular,and people continued to write with pens.They used bird feathers as pens. Then,in 1795,someone started making pencils from graphite(石墨),and they became very popular.One pencil can write 50,000 English words or make a line 55 kilometers long. People wrote with feather pens and then used pens with metal points.They had to dip(蘸) the point into ink after every few letters.Next,someone invented a fountain pen that could hold ink inside it.A fountain pen can write several pages before you have to fill it again. Two Hungarian brothers,Ladislao and Georg Biro,invented the ballpoint pen.English pilots liked the pens.They couldn’t write with fountain pens in airplanes because the ink leaked out.Later,a French company called Bic bought the Biros’ company. Some people call ballpoint pens “Bics”.Australians call them “Biros”.Whatever we call them,we use them every day. feather pen and ink fountain pen ballpoint pen The pen is leaking. 26.Who described a pencil in 1565?( ) A.A Canadian.

The image search engine(图像搜索引擎) Some inventions can save lives or explore the universe(宇宙).There are also inventions made by teenagers to improve the quality(质量) of people’s lives.David Liu,for example,developed an image search engine.It is easier and faster to find images online.With this invention,he won second place in a contest. Teach a robot to learn a language Advanced(先进的) robots can solve problems by themselves.In the future,with the help of artificial intelligence technology(人工智能技术),robots will be able to think and express their ideas like humans.How do we tell a robot what we want it to do? Luke Taylor,a South African high school student,has developed an interesting system.It can teach robots to understand voice commands(命令).Taylor’s software allows him to send commands in English to the robot.The robot’s memory translates them into code(代码) and carries out the commands. Space exploration balloons(太空探索气球) Exploring space usually costs a lot,but Spanish students have proved that weather balloons made of latex(胶乳) can also be used for space exploration.Some students attached(系) special protective devices(防护装置),sensors(传感器) and cameras to the balloons.The balloons could reach a height of 30,000 meters and took many amazing photos.
