Human beings are never satisfied.They have always wanted things to be easier,faster,more comfortable or more convenient.Human history is the history of inventions.(1)________________________.It may be something physical,like a new machine,or it may be a new way of doing something,like the reorganization of production methods in a factory.The earliset inventions,like boats and weapons,were simple but effective ways of meeting basic need and were developed independently by people in different parts of the world who needed to travel or to hunt.Modern inventions are more technical and more specialised.If you come up with an original idea,the first thing to do is to register your invention at the Patent Office.(2)_________________________.
