Since 2000 , we ’ ve gotten many wonderful things like smartphones and driverless cars.But what about what we ’ ve lost ? Let ’ s look at the following things. Calculators They are like tiny computers whose only job is to do math.That is literally all they do.Sure , they could make some amusing swear words.8008 looks like BOOB.And type in 7734 and then turn the calculator upside down and it looks like HELL.But you definitely couldn ’ t get the weather or your email. The busy signal Back in the days of landlines , calling somebody and getting a busy signal used to be annoying.But today , in an age of digital phones , we ’ d give anything to hear a busy signal , because if you hear one , you have some solid information.The person you are trying to reach is home , just on another call.Going straight to voicemail can mean anything.But that beep­beep­beep is a reason for hope! Computer labs In high schools and colleges in the past , there was a specific room where they kept all the computers.Nobody had his or her own computer.Back then that was as absurd as saying “ I could fly commercial , but I prefer to fly my own plane. ” So you went to these rooms and used one of the computers , and then you left and you didn ’ t have access to a computer again until you went back to that room ! Nowadays everyone has his or her own computer. 阅读理解1
