W: Bob, will you tell me something about the new intelligent house your company has just built? I heard that it promises to be a model for houses of the future.

W: OK. So tell me how this house will make my life easier.  
M: When you arrive at the front door, you won’t need a key. [13]The door will open automatically with a touch of your finger; the system can recognize your fingerprint.
