Task 2:Cell

After i listen the audio and read tapescript again i can understand what prof try to tell it is about the cell When mobile phone technology came in a few years ago, the term was immediately shortened.
Mobile phones became 'mobiles'.
Now, cell phone was tricky because some people spelled it as one word and some people spelled it as two.
So it seems you can use both spellings at the moment.
But either way, people shortened the phrase to 'cell'.
nowadays,cell phone is very important to contact everybody and it also waste the time because we no need to wait for a lOng time to speak with somebody...
