从中找出被动语态的句子,一共7个
Over time I have been changed quite a lot.I began as a calculating machine in France in 1642.Although I was young I could simplify difficult sums.I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage.After I was programmed by an operator who used cards with holes,I could “think” logically and produce an answer quicker than any person.At that time it was considered a technological revolution and the start of my “artificial intelligence”.In 1936 my real father,Alan Turing,wrote a book about how I could be made to work as a “universal machine” to solve any difficult mathematical problem.From then on,I grew rapidly both in size and in brainpower.By the 1949s I had grown as large as a room,and I wondered if I would grow any larger.However,this reality also worried my designers.As time went by,as was make smaller.First as a PC(personal computer) and then as a laptop,I have been used in offices and homes since the 1970s.
