all of a sudden突然
It is often difficult to decide on the inventor of certain inventions. This is because sometimes a few people may invent things which are nearly the same. It's hard to tell who came up with the idea first. Some inventions can also lead to other inventions all of a sudden. So some people doubt whether the inventor came up with the idea himself or herself. They think that the inventor used someone else's idea to create his or her invention That is why books or websites usually mention more than one inventor when giving information about inventions.
通常很难判断具体发明的发明者。这是因为有时候一些人可能发明几乎相同的东西。很难说谁是第一个提出想法的人。有些发明也能突然导致其他的发明。因此一些人怀疑是否是发明者他或她自己提出的想法。他们认为发明者用别人的想法创造了他或她的发明。那就是为什么书本或网站在给出有关发明信息的时候通常提到不止一位发明者。
