“universal machine” to solve any mathematical ter，people discovered the computer had “artificial intelligence”.in the 1960s，the computer got his new transistors.its size was totally changes at that time.and in the early 1960s，the first family of computers were connected to each other.in 1970s，computers have brought into people’s homes.now computers have been used by billions of people to deal with information and communicate with each other around the world by the internet.t：congratulations!you’ve done very well.now try to do the same to your partners，ok! step 2 words and expressionstask
