In the near future, we     1     (live) in smart homes with intelligent controls and regular health checks. We will no longer worry about lights on or not when we leave home.     2     instant we enter the door, the lights will come on. If there is something     3     (normal), we can be warned on the phone to prevent more disasters. There’s no doubt that smart homes make life     4     (easy). Nevertheless, it will take some years     5     most new homes begin to use this new technology.
