在这个单元,同学们结识了三位了不起的人物:张衡、怀丙和英国人布斯。他们都是用自己的发明解决实际问题的人。其实,我们每个人都可以是发明家。如果你发现周围有什么东西用起来不太方便,就可以像布斯那样开动脑筋,对现有的东西进行改造,进而形成自己的发明。没准儿,你还可以带着你的新发明,上中央电视台科教频道的《我爱发明》呢! In this module, the classmates met three great people: Zhang Heng, Huai Bing and British Booth. They are all people who use their inventions to solve practical problems. In fact, each of us can be an inventor. If you find something around you is less convenient to use, you can start thinking like Booth, to transform the existing things, and thus form their own inventions. Maybe, you can also bring your new invention, on the CCTV science and education channel “I love to invent” it!
