He has a constant urge___1___(check) for text messages; he checks his phone every five minutes! He's so addicted to it that he just can't stand the idea___2___there may be an important text. He can't help checking even at inappropriate times like when we are eating in a restaurant and I am talking to him! He behaves___3___any small amount of boredom can make him feel the need to check his phone even when he knows he shouldn't. The temptation to see___4___is contacting him is just too great.when I ask him to please put down the phone and stop___5___(ignore) me, he says, "In a minute," but still checks to see if___6___has posted something new on the Internet.
